1978 OATS SURVEY REPORT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Welsch,   Delane E.; Stuthman,   Deon; Showman,   Alan.
A mail survey was conducted in 1977 of farmers who were thought to be oats producers, using names obtained from several lists. The purpose of the 1977 mail survey was to obtain answers to the following questions: (1) What kind of farmer grows oats, (2) Where does he grow them, (3)Why does he grow them, (4) How does he produce them? Answers to these questions should enable the breeding program and the Extension Program at the University of Minnesota to better address the problems of oat production and thus maintain, or hopefully improve the relative competitive ability of oats as a crop in Minnesota.

1998 MICHIGAN PRELIMINARY CASH GRAIN BUSINESS ANALYSIS FOR FARMS SOUTH OF I-96
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nott,   Sherrill B.
A common observation during the autumn of 1998 was that the growing season had been more favorable south of I-96 than it was to the north.  This highway bisects Michigan from roughly Detroit to Muskegon. The following tables are presented for this southern portion of Michigan indicating what farmers in the Telfarm accounting system achieved in terms of crop yields and financial returns during 1998.  It is hoped later reports will show what cash grain farms in the area north of I-96 achieved.

1999 BUSINESS ANALYSIS SUMMARY FOR CASH GRAIN FARMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nott,   Sherrill B.
The sources of the 51 cash grain farms analyzed in this report were Telfarm/MicroTel at Michigan State University, plus the AgriSolutions offices in East Lansing, Adrian, Mt. Pleasant, and Alpena. Farm types were assigned using the 1992 Census of Agriculture's Standard Industrial Classification (SIC) definitions.  Basically, any farm with 50 percent or more of value of farm sales from one item becomes a farm of that type. Cash grain farms have 50 percent or more of value of combined sales from corn, soybeans, wheat, all varieties of navy beans, oats, and other small grains. This report is a summary of the financial and production records kept by cash grain farmers enrolled in the Telfarm/MicroTel record program through Michigan State University Extension.,...

2001 OUTLOOK OF THE U.S. AND WORLD SUGAR MARKETS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2000-2010 by using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes.  Both the U.S. and world sugar economies are predicted to improve over the next ten years after the current over supply is reduced. World demand for sugar is expected to grow faster than world supply, resulting in gradually increasing Caribbean sugar prices from 8.51 cents/lb in 2000 to 12.67 cents/lb in 2010. The U.S. wholesale price of sugar is projected to increase from 22.5 cents/lb in 2000 to 26.6 cents/lb in 2010, if the United States maintains its sugar programs. World...

This report evaluates the U.S. and world wheat markets for the 2000-2010 period by using the Global Wheat Policy Simulation Model.  This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change.  Both the U.S. and world wheat economies are predicted to be improving for the next ten years.  World demands for both common and durum wheat are expected to grow faster than world production of the two wheat classes, resulting in gradual increases in prices of the wheats, which are predicted to increase 5.3% for durum wheat and 1.1% for common wheat for the 2000-2010 period.  World trade volumes of both classes of wheat are expected to expand, but trade volume of durum wheat...

Both the U.S. and world wheat economies are predicted to improve for the next 10 years.  World demand for both common and durum wheat are expected to grow faster than world production, resulting in gradual increases in prices of the wheat varieties.  However, the higher price levels experienced in 2002 and 2003 due to weather conditions will not be maintained in the short-term.  World trade volumes of both classes of wheat are expected to expand, but trade volume of durum wheat...

2005 OUTLOOK OF THE U.S. AND WORLD SUGAR MARKETS, 2004-2013
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2004-2013 using the Global Sugar Policy Simulation Model.  This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to improve slightly over the next nine years after the current over-supply is reduced.  World demand for sugar is expected to grow faster than world supply, resulting in Caribbean sugar prices gradually increasing from 8.40 cents/lb in 2004 to 8.70 cents/lb in 2013.  The U.S. wholesale price of sugar is projected to decrease from 26.15 cents/lb in 2004 to 24.89 cents/lb in 2013, if the United States maintains its sugar programs....

2008 PRECISION AGRICULTURAL SERVICES DEALERSHIP SURVEY RESULTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Whipker,   Linda D.; Akridge,   Jay T.
Precision technologies are now well-integrated into the agricultural industry – both at the farm level and at the crop input dealer level.  No longer are crop input dealers only using the technologies to bring new services to their customers, they are also utilizing the technology in their own businesses to improve the efficiency and effectiveness of their operations.  In early 2008, Crop Life magazine and Purdue University’s Center for Food and Agricultural Business conducted a survey for the 13th consecutive year to assess the adoption of precision agriculture practices in the U.S. from the perspective of the retail crop input dealer.  The questionnaire was mailed to 2500 retail crop input dealerships across the U.S.  A total of 298 questionnaires were...

Autores: Nordquist,   Dale W.; Kurtz,   James N.; Nitchie,   Donald L.; Paulson,   Garen J.; Froslan,   Janet M.; Christensen,   James L.
Average net farm income was $69,787 in 2009 for the 95 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association.  Average earnings decreased by 63%  from $190,901 in 2008.   This continues the downward trend that began in 2008 after six years of steady increases.  As expected, low incomes for virtually all types of livestock operations pulled the average down, and some livestock farms sustained large losses.  Crop farms, on average, were profitable but also earned much lower incomes compared to recent years. Median net farm income, or the income earned by the middle farm, was $96,130, substantially higher than the average.  This indicates that the average was pulled down or skewed by large losses sustained by...

This report evaluates the U.S. and world sugar markets for 2008-2018 using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to remain stable over the next ten years in spite of the 2007-08 surge in world oil prices. That increase in price caused an increase in the conversion of sugar into ethanol in Brazil, while other exporting countries increased their production in response to those higher prices. Sugar prices returned to normal levels in 2008. World demand for sugar is expected to grow at a similar rate to world supply, resulting in Carribean...

This report evaluates the United States and world corn and soybean markets for the 2010-2020 period using the Global Corn and Soybean Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Corn-based ethanol production has influenced United States corn industry. As long as the production of corn-based ethanol remains strong, corn prices will likely remain at a level higher than the long term average. However, changes in the U.S. Federal government subsidies or mandates could significantly impact the world corn market. Under the current assumptions in the model, corn price is expected to remain in a range between $4.68 and $5.35 per...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rahman,   Shaikh Mahfuzur; Dorfman,   Jeffrey H.; Turner,   Steven C.
Cottonseed crushers face substantial risk in terms of input and output price variability and they are limited in their planning by the lack of a viable futures contract for cottonseed or cottonseed products. This study examines the feasibility of cross-hedging cottonseed products using the soybean complex futures. Different cross-hedging strategies are evaluated for eight time horizons relative to the expected profit and utility of the crusher. A Bayesian approach is employed to estimate both model parameters and optimal hedge ratios, allowing consistency with expected utility maximization in the presence of estimation risk. The results reveal that both whole cottonseed and cottonseed products can be successfully cross-hedged using soybean complex futures....

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Banerjee,   Swagata (Ban); Martin,   Steven W.
Agricultural Resource Management Survey (ARMS) data for 2003 were used to estimate two binary logit models for two definitions of genetically modified (GM) cottonseed adoption. Results indicate conservation tillage did not positively affect adoption of GM cotton with either of these definitions, while adoption of GM cotton in the previous year did. Refuge cotton also did not affect these adoption decisions for the study year.

Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

A Binomial Tree Approach to Valuing Fixed Rotation Forests and Flexible Rotation Forests Under a Mean Reverting Timber Price Process
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tee,   James; Scarpa,   Riccardo; Marsh,   Dan; Guthrie,   Graeme.
NPV and LEV are established and common approaches to valuing single rotation and infinite rotation forests respectively, when the rotation age is fixed in advanced. More recently, Real Options approaches have been employed to value single and infinite rotation forests with a flexible harvest age. Under a stochastic timber price process, it has been shown that the valuation of a flexible rotation forest is equal or higher than that of a fixed rotation forest, because a flexible harvest regime delays the harvest if the timber price is not favourable, whereas a fixed harvest regime would proceed to harvest regardless of the price. Often, valuation of fixed and flexible rotation ages are compared using 2 different methods – NPV (or LEV) and Real Options. The...

A bioeconomic model for determining the optimal response to a new weed incursion in Australian cropping systems
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jayasuriya,   Rohan T.; Jones,   Randall E.
Invasions by non-indigenous plant species pose serious economic threats to Australian agricultural industries. When an invasion is discovered a decision has to be made as to whether to attempt to eradicate it, contain it or do nothing. These decisions should be based on long term benefits and costs. This paper describes a bioeconomic simulation framework with a mathematical model representing weed spread linked to a dynamic programming model to provide a means of determining the economically optimal weed management strategies over time. The modelling framework is used to evaluate case study invasive weed control problems in the Australian grains industry.

A BIOECONOMIC SIMULATION APPROACH TO MULTI-SPECIES INSECT MANAGEMENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Boggess,   William G.; Cardelli,   Dino J.; Barfield,   C.S.
Classical approaches to the economics of pest management have focused almost exclusively on single-species models.  This study develops and implements a methodology with which to evaluate multi-species, non-stochastic, managerial decisions subject to stochastic elements of the plant-insect system.  Multi-species insect management strategies (combinations of scouting interval, threshold value, and choice of pesticide) are analyzed using a physiological mechanistic soybean plant growth model coupled to three insect population dynamics models.  Preliminary results indicate that net returns are maximized and variance is reduced with lower thresholds and more frequent scouting than current recommendations.

A BIOTIC CONTROL PERSPECTIVE ON NITRATE CONTAMINATION OF GROUNDWATER FROM AGRICULTURAL PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Erickson,   Jon D.; Schlapfer,   Felix.
Agronomists consider the continuity and nutrient capturing properties of cover crops as important determinants of nutrient cycling in agricultural systems.  Managing for these biotic control functions can help limit nutrient loss and groundwater contamination between main crop harvests.  This simulation study highlights the potential role of cover crop management in a welfare economics framework.  The objective is to find the optimal combination of nutrient input to the main crop, the extent of off-season cover crops, and crop functional diversity to maximize the sum of benefits from agricultural production and groundwater protection.

The development of grain-based ethanol production in Kansas has had a marked impact upon the feedgrain and livestock industries of the state.  The increased focus on feedgrain production stemming from ethanol development impacts the use and sustainability of Kansas water resources, and has changed the proportional mix of crops grown in the state.  The need to handle increased amounts of feedgrains and to transport them to ethanol plants has affected the functional role of local grain elevators as well as the directional flow of grain within the state.  The grain trucking industry has been dramatically affected by the increase in demand for moving both feedstock inputs and co-product outputs to and from ethanol plants in the state.

A closer look at the role of the fruit and vegetable planting restriction provision on land use in the United States
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lei,   Lei; Rickard,   Bradley J.; Balagtas,   Joseph Valdes; Krissoff,   Barry.
Current U.S. farm programs make payments to farmers based in part on historical base acres planted in particular program crops such as corn, soybeans, cotton, wheat and soybeans. Eligibility for payments includes regulations on the crops allowed to be grown on base acres, and there are restrictions on planting horticultural crops on such base acres. The fruits and planting restriction on base acres has potentially influenced the number of acres planted to fruits and vegetables over the past two decades. This research carefully examines the effects of planting restrictions applied to vegetables and program crops, using county-level data in the United States in 1982, 1987, 1992 and 1997.

Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

The impact of hypothetical changes in yields, costs, and demand that might result from the organization of Oklahoma vegetable growers into cooperatives or other multifarmer marketing associations is estimated using a sector programming model. A comparative static analysis is used to evaluate the impact of these changes on planted acreage, growers' revenues, and consumers' and producers' surplus. The results of this analysis indicate that changes in demand are most effective in increasing revenues for Oklahoma growers.

After providing information about the global importance of cotton as a textile and China’s and Australia’s contribution to global cotton production, this paper examines and compares trends in the time-series of cotton production of China and Australia for the period 1980-2007. In doing so, it takes account of changes in the area planted with cotton and its yield. Correlation estimates and decomposition analysis are used to determine the relative contribution to variations in the total output of cotton of changes in the total area planted with cotton and its yield in both countries. These relative contributions are found to be quite different for Australia and China. In addition, there is a comparative analysis of fluctuations in the production of cotton,...

A Comparison of Auction and Choice Experiment: An Application to Consumer Willingness to Pay for Rice with Improved Storage Management
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Su,   Lianfan; Adam,   Brian D.; Lusk,   Jayson L.; Arthur,   Frank.
Experimental auction and discrete choice experiment are two popular value elicitation methods. Theoretically they should yield the same results but empirical results have been mixed (e.g., Lusk and Schroeder 2004, 2006; Corrigan et al. 2010.) This study uses both methods to determine consumers’ willingness to pay (WTP) for rice with improved insect control and for rice stored using Integrated Pest Management (IPM). This study investigates two potential reasons – anchoring and information – for why some studies have found apparent inconsistencies between auction and choice experiment results. Results indicate that consumers’ WTP derived in the auction and choice experiments are significantly different. Consumers’ average bids in the auction are higher than...

A Comparison of Risk and Return Characteristics of Efficient Crop Portfolios for the Brown Soil Zones Saskatchewan and Mecklenburg, Germany
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schoney,   Richard A.; Moeller,   Christof.
Two efficient farms are constructed for the brown soils of Saskatchewan, Canada and for Mecklenburg, Germany based on producer panels. Both farms feature highly integrated cropping systems which take advantage of cropping synergies. However, farm risk is inherently different between the two because differences in 1) climate that gives rise to very different yield risk and cost structure, and 2) EU programs which offer fixed cash payments and stable sugar beet prices. As expected, risk is much higher for the Saskatchewan case farm - it has a chance of a negative cash flow of approximately one year in five. In sharp contrast, the Mecklenburg has very little chance of generating a negative cash flow. Hence, it is easy to understand why crop insurance and...

A COMPARISON OF SUBJECTIVE AND HISTORICAL CROP YIELD PROBABILITY DISTRIBUTIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pease,   James W.
Forecast distributions based on historical yields and subjective expectations for 1987 expected crop yields were compared for 90 Western Kentucky grain farms.  Different subjective probability elicitation techniques were also compared.  In many individual cases, results indicate large differences between subjective and empirical moments.  Overall, farmer expectations for 1987 corn yields were below those predicted from their past yields, while soybean expectations were above the historical forecast.  Geographical location plays a larger role than crop in comparisons of relative variability of yield.  Neither elicitation technique nor manager characteristics have significant effects on the comparisons of the forecasts.

A Comparison of the Great Mississippi River Floods of 1993 and 2011: Implications for Crop Insurance and Reinsurance
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vergara,   Oscar.
The flooding situation in 2011 is similar in nature to the Great Mississippi Flood of 1993, but different in the particulars. First, the timing of the flood within the growing season is different. Second, the two floods occurred in different regions, with the 1993 flood affecting a portion of the Corn Belt and the 2011 flood affecting a region farther south. While floodwaters have inundated several million acres of cropland in 2011, yield losses from delayed planting are expected to be limited. Furthermore, the affected states from the current flood are primarily Group 2 states under the current SRA, which are provided with greater reinsurance protection by the government than the Group 1 states.

This study evaluates all USDA cotton supply and demand estimates for the United States and China (including unpublished price forecasts) from 1985/86 through 2009/10 for accuracy and efficiency. Results reveal that at every stage of the forecasting cycle forecast smoothing was the most widespread and persistent type of inefficiency observed in most U.S. variables. Correlation with past errors indicated the tendency to repeat past errors in most cases. Tendency to overestimate growth was also found. Bias was uncommon and limited to several cases of overestimation of China’s exports and U.S. price and underestimation of China’s domestic use. While forecasts of China’s imports and endings stocks improved, U.S. price and ending stock forecast errors became...

Autores: Marra,   Michele C.; Gould,   Thomas D.; Porter,   Gregory A.
A model is developed to determine the minimum weed population where a decision to apply a postmergence herbicide would be profitable.  The economic threshold model accounts for changing economic conditions, the effect of weeds on crop quality, the effect of multiple weed species on yield and quality, and uncertainty about spraying period length.  The model is uncomplicated enough for microcomputer or programmable calculator applications. An example of weed threshold calculations for round white potatoes is given.

Autores: Gineo,   Wayne M.
Product attributes that determine nursery-stock sales from wholesalers to retail garden centers and landscapers were studied.  Conjoint analysis was used to obtain data on buyer preferences.  The data were analyzed using ordinary least squares and logit procedures to determine the attributes that are preferred by buyers.  It was determined that good- to excellent-quality stock, offerings with a full line of additional plants, taller plants, and cash discounts are desirable attributes.  Quality is the dominant attribute affecting preferences.  Packaging the preferred attributes together significantly increases the probability of a plant being purchased by buyers.

Também, apresenta uma análise da governança citrícola brasileira atual, que está pautada por estratégias diferentes entre citricultores e processadoras: os citricultores e sua principal associação pautam suas principais ações nas utilizações de recursos políticos e algumas grandes processadoras de suco avançam com utilizações de recursos jurídicos. Esse embate revela um novo entrave para a conquista de resultados positivos pelos citricultores na rede de poder atual, pois os mandados judiciais revelam que o contrato de fornecimento de...

A cultura da goiaba encontrou condições favoráveis de clima e solo na região, além do mercado propiciado pela agroindústria local, condições essas necessárias à expansão da atividade. O aumento da área cultivada com goiaba tem sido uma preocupação dos agentes locais ligados ao setor, produtores rurais e agroindustriais, em virtude do alto custo de transporte para importar de outras regiões a goiaba que as agroindústrias locais necessitam para o seu processamento, o que demonstra a importância dessa fruteira para a economia regional. A cultura da goiaba tem sido favorecida na região, também, pela utilização de alguns fatores de produção que se tornaram ociosos nas propriedades agrícolas com o declínio da cacauicultura e que implicam na redução do custo de...

The study presents an analysis of the coordination between the cassava's producers and the cassava's processors industry located in the west of State of Parana (Brazil). In a few years this chain became dynamics because of many factors, such as the institutional that is the most important one. In the last years it was verified a large volatility in cassava's production and price, that compromised the chain performance, mainly the cassava's starch modified production and price, which has high aggregate value. One of this oscillations cause, among other reasons was the lack of coordination between agents. To find evidences and solutions to the studies answers, the new institutional economy approach was studied. Three cassava's starch industries were analyzed...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hebie,   Sekou.
As in almost all sub-Saharan African countries, agriculture plays an important role in the economic life of Burkina Faso. The World Bank's 1983 report indicates that agriculture's contribution to the country's Gross Domestic Product (GDP) was 41 percent in 1981 compared to 16 percent for the industrial sector.  In 1980, exports of agricultural products (basically cotton, groundnuts, and livestock) accounted for 89 percent of total export earnings.  The country is primarily agricultural, with nearly 90 percent of the population dependent on agriculture as a livelihood.  Yet it is well known today that Burkina Faso, going into its third decade as a sovereign nation, is still facing, like its Sahelian counterparts, one of the biggest challenges of economic...

The objective of this research was to provide USAID with a diagnostic-prescriptive  assessment of the mango commodity system that would be useful in the design and management of  USAID’s project portfolio. A secondary objective was to demonstrate how a market-guided food  systems approach could be applied to a particular commodity, thus facilitating coordination of  vertical stages in the agricultural production and marketing system. The food systems approach  begins with identification of consumer requirements in terms of product specifications and volume  flows, examines the production changes necessary to achieve these requirements, then  systematically diagnoses constraints at each stage in the production/marketing chain, and  prescribes realistic...

A diffusion model for the adoption of agricultural innovations in structured adopting populations
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McRoberts,   Neil; Franke,   A.C.
We introduce a new model for examining the dynamics of uptake of technological innovations in agricultural systems, using the adoption of zero-till wheat in the rice-wheat system in Haryana state, India, as a case study. A new equation is derived which describes the dynamics of adoption over time and takes into account the effect of aggregation (e.g. on a spatial and/or cultural basis) in the adopting population on the rate of adoption. The model extends previous phenomenological models by removing the assumption of homogeneity in the non-adopting fraction of the population. We show how factors affecting the per capita rate of adoption can be captured using cognitive mapping and simulate the dynamics of the adoption process.

A Dynamic Adoption Model with Bayesian Learning: Application to the U.S. Soybean Market
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ma,   Xingliang; Shi,   Guanming.
Agricultural technology adoption is often a sequential process. Farmers may adopt a new technology in part of their land first and then adjust in later years based on what they learn from the earlier partial adoption. This paper presents a dynamic adoption model with Bayesian learning, in which forward-looking farmers learn from their own experience and from their neighbors about the new technology. The model is compared to that of a myopic model, in which farmers only maximize their current benefits. We apply the analysis to a sample of U.S. soybean farmers from year 2000 to 2004 to examine their adoption pattern of a newly developed genetically modified (GM) seed technology. We show that the myopic model predicts lower adoption rates in early years than...

A DYNAMIC ANALYSIS OF OPTIMAL WATER USE UNDER SALINE CONDITIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Knapp,   Keith C.; Dinar,   Ariel.
Irrigation with saline waters is a major problem in many parts of the world.  Economic questions have usually been addressed using synthesized production functions and theoretically based soil salinity relations.  The purpose of this paper is to estimate functions relating crop yield and salt accumulation in the soil to initial soil salinity and water quantity and quality.  Crop response functions and dynamic salt balance relations are estimated from experimental data for alfalfa and cotton.  The estimated functions are then used in a dynamic programming model to determine optimal water applications for different levels of initial soil salinity and crop and water prices.

A DYNAMIC ANALYSIS OF THE IMPACT OF WATER QUALITY POLICIES ON IRRIGATION INVESTMENT AND CROP CHOICE DECISIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wu,   JunJie; Mapp,   Harry P., Jr.; Bernardo,   Daniel J.
A dynamic model is developed to analyze farmers' irrigation investment and crop choice decisions under alternative water quality protection policies.  The model is applied to an empirical example in the Oklahoma High Plains.  The choices of crops and irrigation systems and the resulting levels of irrigation, income, and nitrogen runoff and percolation are simulated over a ten-year period.  An effluent tax on nitrogen runoff and percolation is shown to be effective in reducing nitrate pollution.  The efficacy of cost sharing in adopting modern irrigation technologies and restrictions on irrigation water use depends on soil type.  A tax on nitrogen use is shown to be the least effective policy.

A computerized grain sorghum plant growth model is combined with recursive programming to analyze the potential irrigation water savings from adopting irrigation scheduling and low pressure center pivot irrigation technology. Results indicate that irrigation pumping can be reduced with increased yields and net returns by adopting low energy precision application (LEPA) irrigation systems. Variations in input and output prices affect optimal irrigation quantities for low pressure irrigation systems less than for high pressure systems.

A Dynamic Decision Model of Technology Adoption under Uncertainty: Case of Herbicide-Resistant Rice
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Annou,   Mamane Malam; Wailes,   Eric J.; Thomsen,   Michael R.
Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production.  Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty.  The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans.  The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

A DYNAMIC INVESTMENT MODEL FOR TREE CROP AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ajobo,   Owolabi.
The objective of this paper is to develop a dynamic model that may be useful in the analysis of investment in long term tree crop agriculture.  The model is based on linear programming as modified by fixed assets theory.  The starting point is the Heady-Loftsgard dynamic linear programming model restated in a stochastic form and imbedded in a decision theoretic construct to give a stochastic mixed integer programming model.  The paper goes into a discussion of problems associated with agricultural data collection in Nigeria-on the conviction that specific use of any model can only come after the data problem has been reasonably solved.

Autores: Karp,   Larry S.; Perloff,   Jeffrey M.
A linear-quadratic, dynamic feedback oligopoly model that nests various market structures is used to estimate the degree of competitiveness and the adjustment paths of the two largest coffee exporters, Brazil and Colombia. Their estimated behavior is relatively competitive. This subgame perfect dynamic model is-compared to a standard static oligopoly model and the open-loop model (the dynamic generalization of the standard static model). Both classical and Bayesian tests of open-loop and feedback dynamic models are reported.

A Dynamic Nutrient Carryover Model for Pastoral Soils and its Application to Optimising Fertiliser Allocation to Several Blocks with a Cost Constraint
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Woodward,   Simon J.R.
A dynamical model of soil phosphorus carryover in grazed pasture provides the basis for bioeconomic optimization of fertiliser rates. A linear constraint is introduced to optimise the allocation of limited funds to fertiliser on several farm blocks, each of which represents a different land and/or stock class. The optimal constrained maintenance application of fertiliser to each block is calculated, and an heuristic approach to this equilibrium is suggested. In some cases this involves withholding of fertiliser from unresponsive blocks. The dynamical model and economic optimisation method have been implemented in a commercial fertiliser planning decision support tool Outlook.

A Dynamic Optimal Crop Rotation Model in Acreage Response
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cai,   Ruohong; Bergstrom,   John C.; Mullen,   Jeffrey D.; Wetzstein,   Michael E.
This paper presents a dynamic crop rotation model that shows how crop yield and price volatility could impact crop mix and acreage response under crop rotation considerations. Specifically, a discrete Markov decision model is utilized to optimize producers’ crop rotation decision within a finite horizon. By maximizing net present value of expected current and future profits, a modified Bellman equation helps develop optimum planting decisions. This model is capable of simulating crop rotations with different lengths and structures. Specifically, the corn-soybeans rotations were simulated using the crop rotation model.

A Dynamic Optimisation Model of Weed Control
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jones,   Randall E.; Cacho,   Oscar J.
It is argued in this paper that static approaches to weed management, where the benefits and costs are only considered within a single season, are inappropriate for assessing the economic benefits of weed control technologies. There are carryover effects from weed management as weeds that escape control in one season may reproduce and replenish weed populations in following seasons. Consequently, it is appropriate to view weed control in the context of a resource management problem where the goal is to determine the optimal inter-temporal level of weed control that maximises economic benefits over some pre-determined period of time. A dynamic optimisation model for weed control is presented. Using the tools of comparative static analysis and Pontryagin's...

A Dynamic Programming Approach to the Economic Control of Weed and Disease Infestations in Wheat
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fisher,   Brian S.; Lee,   R.R.
Weeds and fungal diseases cause significant losses to grain crops in Australia. In many cases cultural methods of control are effective. However, it is often difficult for farm decision-makers to select the optimum crop rotation, from an economic point of view, given the technical constraints they face. A decision to plant a particular crop will have implications for both current and future profitability because the current decision will alter the constraints faced by the decision-maker in subsequent periods. Dynamic programming is used to solve the rotation problem faced by grain growers in north-western New South Wales in areas where the weed, wild oats (A vena falua or A vena ludoviciana), and the disease, crown rot (Fusarium graminearum Group I), have...

Tedera (Bituminaria bituminosa C.H.Stirt var. albomarginata) is a drought tolerant perennial legume originating in the Canary Islands. This study evaluates the potential role and value of tedera in dryland mixed crop and sheep production systems in southern Australia. Regional variants of the bio-economic model MIDAS are used to assess tedera in farming systems at two locations. The analysis considers the quantity and quality of feed produced by tedera, the ability of other forages to complement or substitute for tedera and its impact on meat versus wool-producing sheep flocks. The results indicate that tedera offers the potential to increase farm profits by up to 26% and be grown on ~28% of a low rainfall mixed enterprise farm. On a high rainfall mixed...

A Flexible Parametric Family for the Modeling and Simulation of Yield Distributions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ramirez,   Octavio A.; McDonald,   Tanya U.; Carpio,   Carlos E.
The distributions currently used to model and simulate crop yields are unable to accommodate a substantial subset of the theoretically feasible mean-variance-skewness-kurtosis (MVSK) hyperspace. Because these first four central moments are key determinants of shape, the available distributions might not be capable of adequately modeling all yield distributions that could be encountered in practice. This study introduces a system of distributions that can span the entire MVSK space and assesses its potential to serve as a more comprehensive parametric crop yield model, improving the breadth of distributional choices available to researchers and the likelihood of formulating proper parametric models.

Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.

A fruticultura irrigada foi introduzida no Rio Grande do Norte, no final dos anos 70, pela empresa Maisa Agroindustrial S/A – MAISA, através do cultivo de melão. A partir da década de 80 outras empresas, como por exemplo, a FRUNORTE passaram a produzir melão e outras frutas na região. Porém, a partir de meados da década de 90, o melão passou a ser produzido também por médios e pequenos produtores da região, inclusive por produtores de áreas de assentamentos de Reforma Agrária, os quais se tornaram fornecedores do produto para a agroindústria – que se encarregava da venda do melão junto aos mercados externo e interno (COSTA, 2002).

A Fully Calibrated Generalized CES Programming Model of Agricultural Supply
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Merel,   Pierre R.; Simon,   Leo K.; Yi,   Fujin.
The use of prior information on supply elasticities to calibrate programming models of agricultural supply has been advocated repeatedly in the recent literature (Heckelei and Britz 2005). Yet, Mérel and Bucaram (2009) have shown that the dual goal of calibrating such models to a reference allocation while replicating an exogenous set of supply elasticities is not always feasible. This article lays out the methodological foundation to exactly calibrate programming models of agricultural supply using generalized CES production functions. We formally derive the necessary and sufficient conditions under which such models can be calibrated to replicate the reference allocation while displaying crop-specific supply responses that are consistent with prior...

A termésmennyiségek prognózisa azt mutatta, hogy a búza, a kukorica és a napraforgó esetében emelkedés várható, amit a hosszú távú ciklusok jövőben várható konjunktúrája még jobban fel fog erősíteni. Az állatállomány trendjének öt éves előrejelzése alapján kirajzolódott az a korántsem pozitív kép, hogy ha a múltbeli tendenciák tovább folytatódnak a sertés- és a...

A GABONAPIACI KERESLET SZEREPLŐINEK ÁTALAKULÁSA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kemenyne Horvath,   Zsuzsanna.
A tanulmány bemutatja a hazai gabona keresletében bekövetkezett vertikális és horizontális átrendeződést és annak hatásait. A kérdőíves megkeresés és a mélyinterjúkból született válaszokat felhasználva, klaszteranalízis segítségével lehetővé vált a felvásárlói oldalon álló szereplők tipizálása, továbbá az áralku döntéseik modellezése. Megállapítható, hogy a gabonapiacon elsősorban a nagy kereskedelmi cégek és holdingok az árvezetők, ami méretükkel, tároló kapacitá-saikkal, logisztikai adottságaikkal és stratégiájukkal magyarázható. A feldolgo-zók (malom, takarmánykeverő, vetőmagos cégek), az integrátorok, kiskereskedők és egyéb cégek árelfogadók a gabonapiacon. Az intervenciós árszint a keresleti oldalon álló szereplők áralkuit, gabonapiaci stratégiáját...

A gap analysis of confined field trial application forms for genetically modified crops in East Africa: evaluating the potential for harmonization
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Linacre,   Nicholas A.; Cohen,   Joel I.
The regulatory approval of genetically modified crops in the field initially requires small, restricted experimental trials known as confined field trials. These small scale experiments provide researchers with important information on environmental interactions and agronomic performance of the crop in a safe and contained manner. To authorize confined field trials regulatory review is required, with formats for obtaining relevant information differing from country to country. In this paper, a Gap Analysis is used to identify informational gaps and potential for harmonization of confined field trial application processes in three East African countries - Tanzania, Kenya, and Uganda. The basic principle behind gap analysis is a comparison of the status quo...

A gender performance indicator for irrigation:  Concepts, tools and applications
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: van Koppen,   Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

Autores: Cervantes,   Carlos F.
Among the different institutions through which the Costa Rican government influences production and internal marketing of agricultural commodities, the Consejo Nacional de Produccion (CNP) is the most important one.   The Consejo is given by law a great deal of authority in fomenting production and stabilizing prices of food products.  It is also entitled to perform a wide range of activities and marketing functions affecting the food system (buying and selling, assembling, transporting, storing and processing, importing and exporting, price fixing, input distribution, etc.).  Because of the strategic role of agriculture in the country, and due to very significant influence of the Consejo's intervention upon production, marketing and consumption in...

Autores: Sivaraman,   Eswar; Lyford,   Conrad P.; Brorsen,   B. Wade.
The Hennessy and Wahl model of optimal grain blending and segregation (GBS) is extended to the case where it is not possible to separate components within a load. Analytical solutions are not available when segregation is the optimal strategy, and so solutions are obtained with nonlinear optimization. The model is then used to determine the optimal sorting of hard red winter wheat by protein content.  Most of the benefits from sorting can be obtained with only two bins.

A Genetically Engineered Crop's Impact on Pesticide Use: A Revealed-Preference Index Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sydorovych,   Olha; Marra,   Michele C.
A revealed-preference-based method is proposed for assessment of the environmental and human health impact of genetically engineered (GE) crops.  This method employs the relative pesticide toxicity information from farmers' pesticide choices combined with volume of pesticides as an alternative to previous methods which are based on volume only, on number of pesticide applications, or on stated preferences.  The method is applied to estimate the changes in the impact of herbicides after environmental and health perspective.  The results indicate that, on average, a reduction in herbicide human heath and environmental impacts occurs when farmers adopt RR soybean varieties.

A Globally Flexible Model for Crop Yields Under Weather Risk
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cooper,   Joseph C.; Wallander,   Steven.
The literature on climate change and crop yields recognizes the need to allow for highly non-linear marginal effects.  This study combines these two areas of the literature by using Flexible Fourier Transforms (FFT’s) to ensure flexibility for both the time trend and the weather effects.  This study also illustrates how FFT’s can be combined with quantile regression (QR) to provide both robustness to outliers and information on the scale effects of time and weather variables. For U.S. county level data on corn, soybeans, and winter wheat, we estimate the relationship between yield and temperature and precipitation using a traditional parametric expected-yield estimator, our quantile-FFT regression evaluated at the median, and our QR-FFT regression that...

A GROSS MARGIN COMPARISON OF RETURNS TO NEMATICIDE TREATMENT IN CONTINUOUS AND ROTATION TRITICALE-SOYBEAN PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Stark,   C. Robert, Jr.; Dowler,   C.C.; Johnson,   A.W.; Baker,   S.H.
A study of irrigated strip-till soybean production compared gross margins over nematicide expense for a continuous triticale-soybean system versus a two-year rotation system alternating triticale-soybean with triticale-cotton. Half of the replicated plots under each system received nematicide treatment. Gross margins were calculated using recorded yields and Georgia average market prices by marketing years. Mean gross margins for untreated plots were not significantly different between crop-sequence systems. Within each system, however, mean gross margins were significantly higher for plots not receiving nematicide treatment versus treated plots, even when treated plots produced greater yields.

A GSD ESTIMATION OF THE RELATIVE WORTH OF COVER CROPS IN COTTON PRODUCTION SYSTEMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Giesler,   G. Grant; Paxton,   Kenneth W.; Millhollon,   E.P.
Cover crops can help reduce the negative environmental impacts of cotton production. Using time series yield data, this study utilizes generalized stochastic dominance to evaluate the relative worth, via risk premiums, of three cover crop and two conventional production systems based on expected net returns of each system and decision maker risk attitude. Results indicate, within the limitation of the study, two cover crop regimes possess a high degree of dominance over conventional systems. Determination of the dominant regime depends upon the risk attitude of a specific decision maker. This research suggests cover crop production systems may be feasible alternatives to conventional practices.

A magyarországi zöldség- és gyümölcságazat felkészülése az uniós csatlakozásra nem volt igazán eredményes, uniós tagságunk eddigi tapasztalatai, eredményei is felemásak. A csatlakozásnak eddig több a negatív, az ágazat jövőjét veszélyeztető következménye, mint a pozitív hozadéka. A korábbi gyengeségek – alacsony szervezettség, elavult műszaki színvonal, hiányos logisztikai rendszerek, elaprózott birtokstruktúra, szélsőségesen differenciált termelési (gazdálkodási) színvonal – következtében itthon piacvesztés, strukturális feszültségek jöttek létre.

Autores: Huang,   Chung L.; Lin,   Biing-Hwan.
The food habits and dietary patterns of American consumers are changing and they are increasingly demanding food products that possess certain attributes relating to how the food was produced or processed. The objectives of the study are to analyze household purchase of fresh tomatoes and to determine the magnitudes of the price premium paid for the organic tomatoes by estimating a hedonic price model. The study uses the 2003 ACNielsen Homescan panel data. The data set represents a nationally representative panel of U.S. households, which provide food purchase data for at-home consumption. For empirical implementation, parameters of the hedonic model were estimated using the Box-Cox transformation procedure. The results indicated that consumers value the...

A hedonic approach to estimating the supply of variety attributes of a subsistence crop
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Edmeades,   Svetlana.
The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of...

A HEDONIC MODEL OF RICE TRAITS: ECONOMIC VALUES FROM FARMERS IN WEST AFRICA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dalton,   Timothy J.
New crop varieties often have been promoted in developing countries based upon superior yield vis-a-vis locally available varieties.  This research presents a hedonic model for upland rice by drawing upon the input characteristics and consumer good characteristics model literature.  Model specification tests determine that a combination of production and consumption characteristics best explains the willingness to pay for new upland rice varieties.  This non-separable household model specification determined that four traits explain the willingness to pay for new rice varieties: plant cycle length, plant height, grain elongation/swelling and tenderness.  Yield was not significant explanatory variable for the willingness to pay for seed.  The implications...

Autores: Vassalos,   Michael; Dillon,   Carl R.
Herbicides account for approximately 2.2% of total farm expenses and are applied to more than 80% of farmland in the USA. The widespread adoption of herbicides contributed to the increased and relatively cheaper productivity of modern intensively managed agricultural systems in developed countries. The present study uses a hedonic framework to analyze the effect of selected attributes on the price of corn and soybean herbicides. Two different empirical models were estimated separately for the two crops. The data include information on 51 herbicides, 27 for corn and 24 for soybean crops used in Kentucky. Findings indicate that efficacy against weeds and crop response (illustrates the potential of an herbicide to injure a crop) of herbicides are significant...

This study estimates a hedonic price equation to assess consumers' willingness-to-pay for reduction in pesticide residues in fifteen fruits and vegetables.  A unique feature of the study is its employment of the FDA's Total Diet Study  data which attempts to measure actual pesticide ingestion by the American public in table-ready or prepared foods.  The results indicate that consumers would be willing to pay approximately $.08 per pound to reduce pesticeds by one part per million in the prepared fruits and vegetables that they consume.

A LINEAR APPROXIMATE ACREAGE ALLOCATION MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Holt,   Matthew T.
It is shown that the first-order differential acreage allocation model developed by Bettendorf an Bloome and by Barten and Vanloot, and based on certainty equivalent profit maximization, may be extended to a levels version. The levels model, referred to as a linear approximate acreage allocation model, is potentially useful when panel or cross-sectional data are employed. An empirical application with U.S. state-level corn flex acreage data for the period 1991-95 indicates the feasibility of the approach. Estimated price and scale elasticities are generally larger than previous estimates, and are perhaps indicative of acreage response under the provisions of the 1996 Farm Act.

Agriculture is the largest sector in the economy of Sierra Leone, employing approximately 75 percent of the population in 1972 and accounting for over 30 percent of the gross domestic product.  But though the national economy has grown at an estimated 4.3  percent rate in the last decade, the agricultural sector is estimated to have grown only 1.6 percent per year.  The government of Sierra Leone, recognizing the importance of the agricultural sector and the need to develop policies to encourage its growth, has set a goal of increasing the growth rate of the sector to 4.6 percent per annum.  Central to the overall agricultural development plan is the emphasis on increased rice production.  Rice is the staple food in Sierra Leone, grown by over 80 percent...

Autores: Jin,   Hyun Joung.
The study explores a long memory conditional volatility model on international grain markets, demonstrating importance of modeling both temporal effects of volatility and long memory process. This study adopts six different volatility models, nested in an ARMA(p,q)- FIGARCH(P,D,Q), to capture dependence of grain cash price volatility and compares the performance of the six models. It also visits a related question about non-normal behaviors of grain prices and adopts the student-t density intended to account for fat-tailed properties of the data. We find suitability of the FIGARCH type models under the student-t distribution and competitiveness of the parsimonious FIGARCH(1,d,0) for modeling long memory volatility.

Igaz, hogy a szélsőséges időjárás Magyarországon rendkívül nagy hozamingadozásokat okozhat, az agrárpolitika és a piaci szereplők pedig hajlamosak a túlzott reakciókra, mégis a gabonaágazat az, ahol a magyar mezőgazdaság a természeti adottságok, a termelés vonatkozásában még bizonyíthatóan komparatív előnyökkel rendelkezik az Európai Unióban. A szántóföldi növények nemzeti kiegészítő támogatása ugyan 2008-tól a termeléstől függetlenedik, de a gazdálkodók a rendelkezésre álló szántóterületet a jövőben is hasznosítják, mert a gabonafélék magas ára ösztönzi a termelést.

A MAGYAR ÖKOTERMELÉS ÁTTEKINTÉSE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gyarmati,   Gabor.
A hazai ökológiai gazdálkodás növekedési pályára állt az ezredforduló táján, de 2004-től a vállalkozások számának és az ökológiai művelés alá vont területek nagyságának növekedési mértéke csökkent, majd visszaesés következett be. Az ökológiai termelést végző vállalkozások nagy része jó adottságokkal rendelkező nagygazdaság, amelyek párhuzamos termelést folytatnak, és olyan elkötelezett kisvállalkozás, amelyek gazdasági súlya nem jelentős. Egyes rossz adottságú gazdaságok földjeiket átállítják ökológiai státuszra, a támogatás végett. A műve-lési ágak között nagyobb a gyep (rét, legelő, 53,6%) és alacsonyabb a szántó (26,4%) aránya. A gyepterületek könnyen átminősíthetők ökológiai területté, vi-szont gazdasági értékük nem jelentős. A vetésszerkezetben a...

A magyar zöldség- és gyümölcságazatok külkereskedelmi versenyképességének alakulása
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Medina,   Viktor.
A vizsgálatok eredményei alapján megállapítható, hogy a zöldség- és gyümölcságazatok versenyképesek, de a versenyképesség évről évre csökken. A versenyképesség romlása az uniós csatlakozással nem szűnt meg, sőt erősödött, ami részben az ágazat felkészületlenségének, részben a 2004. évi bő termésnek és a 2005. év kedvezőtlen időjárásának köszönhető. Kedvezőtlen eredmény az is, hogy a pozícióromlás legnagyobb mértékben a célpiacokon észlelhető. A termékköröket külön elemezve látható, hogy a versenyképességi mutatók a legkedvezőbbek a feldolgozott termékeknél. Ezt követik a friss zöldségek. A friss gyümölcsnél már nem is beszélhetünk versenyelőnyről. Ennek a magyarázatát elsősorban a jelentős mértékben megnőtt déligyümölcsimport adja. A kedvezőtlen...

A MATHEMATICAL PROGRAMMING MODEL FOR VEGETABLE ROTATIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Musser,   Wesley N.; Alexander,   Vickie J.; Tew,   Bernard V.; Smittle,   Doyle A.
Rotations have historically been used to alleviate pest problems in crop production.  This paper considers methods of modeling rotations in linear programming models for Southeastern vegetable production.  In such models, entering each possible crop rotation as a separate activity can be burdensome because of the large numbers of possible rotational alternatives.  Conventional methodology for double crop rotations reduces the number of activities but must be adapted to accommodate triple crop rotational requirements in vegetable production.  This paper demonstrates these methods both for a simple example and an empirical problem with numerous rotation alternatives.  While the methods presented in this paper may have computational disadvantages compared to...

A Methodology for Measuring Potential Benefits from Drought-Oriented Research in Nebraska

The growth in agricultural productivity and significance of science and technology in contributing to this growth has been well documented by Bredahl, Cline, Evenson (1967), Griliches (1964), and Peterson. The results of these studies generally indicate that over the past several decades, investment in agricultural research has paid off with relatively high rates of return. Most of this previous work, however, has been directed at estimating returns to aggregate agricultural research in an ex post sense at the national level and does not address the question of potential future returns to research at a state or regional level (Norton). Thus, a particular need exists to develop a methodology for evaluating the potential returns to specific types of...

A Multifunctional Comparison of Conventional versus Alternative Olive Systems in Spain by Using AHP
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parra-Lopez,   Carlos; Calatrava-Requena,   Javier.
Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with...

A Multilevel Economic Analysis of the Wheat Market in Pakistan
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ashfaq,   Muhammad; Parton,   Kevin A.; Griffith,   Garry R.; Piggott,   Roley R.
Government price policy in Pakistan affects both the supply and demand of wheat. The wheat market has been established in a particular idiosyncratic manner in Pakistan, and a thorough appraisal of policy needs to take this into account. Hence, to analyse various policy interventions, this study develops a multi-level wheat market model. After considering the real world aspects of the wheat marketing chain, a conceptual framework is developed involving five market levels. This is then translated into a multi-equation econometric model. The model is based on secondary time series data from 1971 to 1996. It consists of equations representing supply, demand, stock holding, importing and price formation. The model is used to estimate changes in consumer...

This report presents the preliminary results of a statistically valid 2006 survey of small agricultural producers (sales of less than $50,000) in three Western states (Wyoming, Colorado and Arizona). The West has undergone significant change, and the composition of farm managers has changed with it. This report provides information from farm operators in the rural West  on their perceived threats as well as characteristics of themselves and their operations. Topics of interest were demographics, reasons for involvement in agriculture, income, resource management (crops and livestock), and preferences for information delivery. The project was supported by the Western Center for Risk Management Education.

A Nonlinear Offset Program to Reduce Nitrous Oxide Emissions Induced by Excessive Nitrogen Application
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rosas,   Francisco; Babcock,   Bruce A.; Hayes,   Dermot J.
On average, U.S. farmers choose to apply nitrogen fertilizer at a rate that exceeds the ex post agronomically optimal rate. The technology underlying the yield response to nitrogen rewards producers who over apply in years when rainfall is excessive. The overapplication of nutrients has negative environmental consequences because the nitrogen that is not taken up by the plant will typically volatilize causing N2O emissions, or leach causing water pollution. We present a nonlinear offset program that induces farmers to reduce their nitrogen applications to the level that will be consumed by the plant in a typical year and, as a result, reduce N2O emissions from agriculture. The offset program is nonlinear because of the nonlinear relationship between N2O...

A Non-Parametric Analysis of Rice Production Efficiency in Sri Lanka
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Thibbotuwawa,   Manoj; Mugera,   Amin W.; White,   Benedict.
This article investigates the production efficiency of rice farming in Sri Lanka using cross section survey data of 90 farms. Past studies on rice farming have mostly focused on technical efficiency (TE). Here, we examine technical efficiency, allocative efficiency (AE) and cost efficiency (CE) using the data envelopment analysis (DEA) approach. On average, the farms were 87% technically efficient; irrigated farms were more efficient (88%) than rain-fed farms (82%). Average cost, allocative and scale efficiencies were 73%, 84% and 87%. Bias corrected TE estimate suggests an expected output expansion of 25% with a given input combination in order to become fully efficient as opposed to 16% based on the original estimates. In addition, a second stage Tobit...

A Practical Algorithm for Multiple-Phase Control Systems in Agricultural and Natural Resource Economics
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Doole,   Graeme J.
Many important problems in agricultural and natural resource economics concern an intertemporal choice between alternate dynamic systems. This significance has motivated a theoretical literature generalizing the necessary conditions of Optimal Control Theory to multiple-phase problems. However, gaining detailed insight into their practical management is difficult because general numerical solution methods are not available. This paper resolves this deficiency through the development of a flexible and efficient computational algorithm based on a set of necessary conditions derived for finite-time, multiple-phase systems. Its effectiveness is demonstrated in an application to a nontrivial crop rotation problem.

Ahhoz, hogy a vidékfejlesztés, a környezetgazdálkodás az agrárgazdaság integrált részévé váljék, a gazdasági gyakorlatnak szá¬mos területen szükséges változtatni: merőben új módszerek alkalmazása, a koráb¬ban használt vagy meglévő technológiák megújítása, mások által már kipróbált eljá¬rások adaptálása, mind-mind egy-egy lehetőséget kínál a jól működő, többfunkciós mezőgazdasághoz. Mindezen okok mérlegelése után döntött úgy az Agárdi Farm Kft., hogy átáll a ha¬gyományos gazdálkodásról a precíziós növénytermelésre. A precíziós növényterme¬lési technológia nem más, mint a...

A Preliminary Analysis of the Benefits of Introducing Apomixis into Rice
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Frisvold,   George B.; Bicknell,   Kathryn; Bicknell,   Ross.
The objective of this research is to undertake an ex ante economic analysis of basic scientific research that aims to identify the gene(s) that control apomictic reproduction, with the ultimate aim of transferring the characteristic into commercially important crops. This paper reports very preliminary results, using the introduction of apomixis into rice as a case study. Apomixis is a natural, asexual method of plant reproduction resulting in offspring that are genetically identical to the mother plant. Apomixis promises to revolutionize plant breeding by providing a system for crop improvement that allows any desired variety, including hybrids, to breed true. This ability will make both breeding and seed production more efficient. It offers the...

A PRELIMINARY ANALYSIS OF THE EFFECTS OF THE PRICING MECHANISMS USED IN THE SOYBEAN SUBSECTOR IN URUGUAY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ugarte,   Galdos G.
Since 1974, Uruguay has adopted an export-led growth strategy of deployment. Macroeconomic policies implemented toward this general objective have achieved impressive results in improving the general economic situation of the country.  Increases in nontraditional manufactured exports have been largely responsible for the improvement in the overall growth performance and have brought about a substantial diversification of the export structure.  Soybeans have also appeared recently as another nontraditional potentially exportable agricultural product.  However, soybean production in Uruguay has not developed enough to make soybean exports an important and permanent source of foreign exchange.  Given the need to diversify the export structure of the country,...

A PRINCIPAL-AGENT MODEL FOR REGIONAL PEST CONTROL ADOPTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ahouissoussi,   Nicolas B.C.
Investigating the underlying producer characteristics associated with regional pest control adoption revealed an interesting proposition. Early adopting producers of firm-specific techniques with characteristics including higher education, more specialized operations, and larger sized business units are dissatisfied with a regional pest control technique. This study provides an explanation of the proposition based on a principal-agent model. Empirical support for the proposition is also presented by developing a multinomial logit model for predicting producers' dissatisfaction with boll weevil eradication.

A PROPOSAL FOR EFFECTIVE TECHNOLOGY TRANSFER
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   Maurice.
The paper examines the performance of the agricultural sector over the 10 year period 1995-2004. Indicators suggest that investments in Agricultural Research and Development (used as a proxy for the quantum of technology generated) have had little impact on agricultural production.  In this regard, an assumption is made that technology generated has neither been adequately transferred nor adopted. Within the above context a holistic model for effective technology generation has been presented.  It is argued that effective technology generation is market driven technology is more likely to be transferred and adopted by agribusiness entities. To implement this process, strategic alliances should be forged in order to address resource limitations. The entire...

A real-options analysis of wine grape farming in north west Victoria
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Seyoum,   Emayenesh; Chan,   Chris.
This paper reports a use of a real-options valuation methodology to analyse wine grape farm investment under price and yield uncertainty. Revenue levels to incentivise entry and exit were calculated for three different sizes of wine grape farms in North West Victoria. The modelling identified lower exit and higher entry triggers than indicated by conventional net present value calculation. The wide gap of estimated indeterminacy in farm investment highlights the intertwined influence of numerous economic factors — cost structure, economies of scale, market volatility, transaction costs, and sunk and salvaged asset valuation. Drawing on these determinants of farm investment and disinvestment, the paper discusses the role of investment incentives in...

A Reexamination of the U.S. Export Demand for Soybeans and Soybean Products
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Uri,   Noel D.; Hyberg,   Bengt.
This paper addresses the question of whether the export demand for soybeans and soybean products changed structurally over the 1950 to 1992 period as the U.S. agricultural sector became more integrated with the rest of the world economy. The results suggest that export demands were stable for soybeans, soybean meal and soybean oil over the sample period. Moreover, it is possible to infer conclusively that the long-run soybean and soybean product export price elasticities were in the elastic range. The implications include that for each one percent reduction in the price of soybeans, soybean meal and/or soybean oil brought about through a government program, exports increased by more than one percent, leading to a reduction in the variability of soybean and...

Four environments with contrasting potential for agricultural productivity and infrastructure development were identified in Guanajuato State, Mexico, to test hypotheses about the relationship of maize biological diversity to the region's potential for agricultural productivity and infrastructure development. Samples of all types of maize grown by a random sample of farmers were collected from each environment. The maize samples were classified by race, racial mixture, or type of 'creolized' or improved variety. Landraces were the dominant maize class in all four environments; the use of improved varieties was negligible. Several diversity indices were calculated, and no statistically significant differences were apparent between the environments with the...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wu,   Tzongyun Katy.
Since the early 1930's, congress has established a number of programs intended to soften the impact of economic forces upon farmers.  These programs seek to adjust production to utilization on a year-to-year basis by offering incentives to producers to expand or contract their crop planting.  As a result, accurate estimates of producer response to changing market prices and government programs are very important for policy makers as they attempt to adjust programs to balance demand and supply.  Good forecasts of future crop acreages can also help economists provide producers and agribusinesses with better guides for strategies and planning, marketing, and production decisions.  The objective of this study is to forecast acreage planted for a specific...

An econometric model of U.S. apple supply and demand is estimated  using annual data for 1971-1997.  Supply is arranged into four geographical regions, the Northwest, the Southwest, the Central, and the East.  The structural model consists of five components: supply, allocation between fresh and processed utilization, pricing, demand and net imports.  Estimated supply elasticities illustrate regional differences in growers' ability to respond to market changes.

A Return of the Threshing Ring? A Case Study of Machinery and Labor-Sharing in Midwestern Farms
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Artz,   Georgeanne M.; Colson,   Gregory; Ginder,   Roger G.
Machinery-sharing provides an alternative for smaller producers to obtain the efficiencies of large farming operations and remain competitive in an increasingly concentrated agricultural industry. This research uses a multiple case study design to examine the motivations for sharing equipment and labor among farms and to better understand how group members handle the transaction costs of sharing. Our case evidence finds that in addition to cost savings, access to reliable labor is an important motivation for participating in a sharing arrangement. Trust and frequent communication among group members helps to minimize the transaction costs incurred from sharing.

A Revenue-Based Alternative to the Counter-Cyclical Payment Program
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cooper,   Joseph C.
This paper develops a stochastic model for comparing payments to U.S. corn producers of a revenue-based counter-cyclical payment (R-CCP) that is offered as an alternative in the 2007 House "Farm Bill" (H.R. 2419) to the current price-based CCP (P-CCP). We minimize the potential for miss-specification bias in the model by using nonparametric and semi-nonparametric approaches as specification checks in the model. Using this model, the paper examines the sensitivity of the density function for payments to changes in expected price levels. A mean-variance utility function approach is used to assess producer preferences for choice of CCP program alternative. The results show that as risk reduction instruments at the farm level, there appears to be little...

The purpose of this paper is the relatively limited one of reviewing the literature for models which develop specific relationships between climatic variables and crop yields. Following a review of recent weather-crop yield modeling efforts we evaluate these models and suggest some conceptual models and data base improvements if we are to adequately project the impacts on crop production of expected future climatic change. Our review and evaluation centers on weather-crop yield models applicable to the central grain belt of the U.S., mainly the Corn Belt and Great Plains production regions.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mucavele,   Firmino Gabriel.
Agriculture surveys and literature establish that sorghum was of the most important food crops in Mozambique.  A large number of farmers have been shifting production gradually from sorghum to maize production despite its susceptibility to drought.  The general objective of this study is to identify the factors responsible for decline of sorghum production in Mozambique.  Comparative analysis between sorghum and maize are done.  Enterprise budgets and break even analysis for both sorghum and maize are presented and discussed.  Supply functions for sorghum and maize from 1950 to 1985 are estimated.  It is concluded that the major factors responsible for sorghum production decline are the lack of security in the country side, drought during the last ten...

Multi-Agent Simulation (MAS) models are intended to capture emergent properties of complex systems that are not amenable to equilibrium analysis. They are beginning to see some use for analysing agricultural systems. The paper reports on work in progress to create a MAS for specific sectors in New Zealand agriculture. One part of the paper focuses on options for modelling land and other resources such as water, labour and capital in this model, as well as markets for exchanging resources and commodities. A second part considers options for modelling agent heterogeneity, especially risk preferences of farmers, and the impacts on decision-making. The final section outlines the MAS that the authors will be constructing over the next few years and the types of...

The quality of agricultural price data has been a growing concern of producers, researchers, and government officials in recent years.  The major work done on improving agricultural price data has, of course, taken place within the United States Department of Agriculture.  These efforts have not only led to the identification of key problems and issues in price reporting but have also resulted in a deeper investigation into our data and information systems.   While an information system theory as such has not been developed, significant contributions have been made in terms of insights gained into the issues, the definitions and the epistemological nature of data systems and information systems.  This study will be done in the context of these insights...

A REVIEW OF RECENT CHANGES IN MEXICAN AGRICULTURAL POLICY:  IMPLICATIONS FOR SMALL SCALE BEAN PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bryant,   Elizabeth.
Until the early 1980s, Mexican economic policy was characterized by import substitution industrialization. Agriculture's role was to provide a cheap and abundant food supply for the urban sector, and to generate foreign exchange through exports. While Mexico achieved food self-sufficiency by the early 1960s, conflicting policies succeeded in undermining basic grain production and exacerbating an existent dichotomy between traditional and rainfed production. Austerity measures imposed during the 1980s resulting from the collapse of world oil prices further undermined small-scale production.   These effects are viewed in the context of the bean subsector, characterized by a bimodal system of production; while the majority of Mexican bean producers are...

A REVIEW OF SELECTED RESEARCH ON POST-HARVEST LOSSES OF GRAINS AND THE UTILIZATION OF FARM LEVEL STORAGE IN DEVELOPING COUNTRIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vaccaro,   Carlos Ma.
An analysis of food production and population trends reveals that mankind will continue to struggle to feed itself.  From 1970-1976, annual per capita food production increased 1.4% in developed countries and at less than 1% in developing ones.  Population growth rates have been declining in the former, but have remained more or less constant and at much higher levels in the latter.  Therefore increasing food supply is more critical in developing countries.  Three approaches are often mentioned to help cope with the possible world food shortage:  1) increase food supplies by increasing production; 2) reduce future increase in demand by slowing population growth; and 3) increase food availability by reducing post-harvest losses.  All three approaches are...

A Ricardian analysis of the impact of climate change on African cropland
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kurukulasuriya,   Pradeep; Mendelsohn,   Robert.
This study examines the impact of climate change on cropland in Africa, using a Ricardian cross-sectional approach. Relying on farm data from an 11-country survey of over 9500 farmers, annual net revenue is regressed on climate and other variables. The study confirms that current climate affects the net revenues of farms across Africa. Applying these results to possible future climates reveals that dryland farms are especially climate sensitive. Even as early as 2020, climate change could have strong negative impacts on currently dry and hot locations. By 2100, dryland crop net revenues could rise by 51% if future warming is mild and wet but fall by 43% if future climates are hot and dry. The crop net revenues of currently irrigated farms are likely to be...

A Rising Tide of Anti-Animal Consumerism? Issues and Opportunities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rae,   Allan N.
The livestock revolution that has occurred over the last few decades has seen a phenomenal increase in demand for livestock products in much of the developing world. This has largely been matched with growth in supplies, driven by government policies, and increased animal numbers and productivity. But this growth has been accompanied by a number of side-effects which in many cases impose negative externalities on society and suggest that current trends in animal product consumption are unsustainable. As a result there is emerging an anti-animal sentiment among some consumer groups. These people are concerned about livestock issues such as human health effects, biodiversity losses, deforestation, emissions to the air and water, diversion of grains from...

A Risk Analysis of Converting CRP Acres to a Wheat-Sorghum-Fallow Rotation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Williams,   Jeffery R.; Llewelyn,   Richard V.; Pendell,   Dustin L.; Schlegel,   Alan J.; Troy,   Dumler.
This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region.  This research uses stochastic efficiency with respect to a function (SERF) to determine the preferred management strategies under various risk preferences and utility-weighted certainty equivalent risk premiums.  Yields, input rates, and field operations from an experimental field in western Kansas are used to calculate net returns for each tillage strategy.  Although current net returns to crop production using reduced tillage and no-tillage strategies are higher than CRP, risk analysis indicates CRP...

Pine wood nematode, B. xylophilus poses a serious threat for the European forest industry. This study applies a quantitative risk assessment to analyze the risk of pine wood nematode in the EU, by estimating the reduction expected within forestry stock available for wood supply and its downstream roundwood market. Spatial analysis is used to join information on climate suitability, host distribution, pest spread and value of assets. Economic impacts are presented spatially on a NUTS-2 scale based on partial budgeting technique and for the EU as a whole based on partial equilibrium modeling. Results highlight the Southern regions of Europe as high risk areas with a total impact on available forestry stock of 19,000 M € after 20 years of an outbreak and no...

A Rule of Thumb for Controlling Invasive Weeds: An Application to Hawkweed in Australia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kompas,   Tom; Chu,   Long.
We use a bang-bang optimal control model to derive a rule of thumb for an optimal management of invasive weeds, in terms of the marginal benefits and costs of various control actions. Instead of determining the size of infestation under an optimal surveillance measure, the rule specifies the types of land where an invasive weed should be first prevented from establishment, and under what conditions control should be initiated. The types of land are modeled via the heterogeneous vulnerability of land to the weed and likely infestation. This easy-to-use rule is applied to determine how hawkweed should be controlled in Australia, across three potential control strategies: containment, eradication and no action. We investigate this rule-of-thumb in both...

Autores: McClintock,   David N.; Ahmadi-Esfahani,   Fredoun Z.; Johnston,   Jim H.
A simulation model is employed to find the least cost way of dealing with the grain carryover during and after completion of harvesting that is caused by a difference between harvesting and trucking capabilities in the short run. The study may potentially aid the farmer in the face of legislative changes affecting wheat marketing, as well as technological changes in harvesting equipment. Results tend to indicate that temporary paddock storage may be more efficient than contract trucking in managing the carryover.

The Western Balkan countries can be characterised by their shared goal, which is rapid accession to the EU. Agriculture is an important element to achieving this goal. The role of agriculture differs widely among the analysed countries but is more important than the average of the EU. This study gives a comprehensive overview of the most important agricultural indicators. These indicators give a precise picture of the sector’s relevance, production structure, efficiency and international relations. After demonstrating changes in input use, production structure, prices and agricultural policies, the next section identifies some of its reasons. The analysis concentrates on the newest available data. Serbia is the leading producer and the only net exporter of...

A source-differentiated Almost Ideal Demand System model is used to analyze U.S. demand for the major tropical fresh fruit imports from different countries of origin. The tropical fresh fruits chosen for analysis include fresh bananas, fresh pineapples, papayas, and mangoes/guavas. To address endogeneity problem, we utilized an iterative 3SLS estimation method. Results show that consumer incomes are a major determinant of tropical fresh fruit import demand and most of the tropical fresh fruit imports are luxury commodities. U.S. consumers have a preference for Guatemalan and Costa Rican bananas, Costa Rican and Honduras pineapples, and Ecuador and Mexican mangoes. A competitive relationship exists between bananas from Ecuador and Colombia, Ecuador and...

A STOCHASTIC DOMINANCE ANALYSIS OF ALTERNATIVE SUGAR BEET- AND NAVY BEAN- BASED CROP ROTATIONS IN MICHIGAN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gebremedhin,   Berhanu; Schwab,   Gerald; Harwood,   Richard R.; Christenson,   Donald; Bricker,   Calvin.
Sugar beets (Beta vulgaris L.) and navy beans (Phaseoulus vulgaris L.) have been important target crops in the crop rotation systems of many Michigan growers, particularly in the Saginaw Valley and the Thumb region.  The recent decline in sugar beet yields combined with the erratic navy bean yields have led to concern about the optimal crop rotation for the East Central region in Michigan.  Risk is an important consideration in a farmer's choice of cropping systems.  This study uses 20 years of experimental data from the Michigan State University Saginaw Valley Research Farm to determine the risk efficiency of alternative sugar beet- and navy bean- based crop rotations that included corn (Zea mays L.), oats (Avena sativa L.), and alfalfa (Medicago sativa...

A STOCHASTIC MODEL FOR THE OPTIMAL REPLACEMENT OF RUBBER TREES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Etherington,   Dan M.
Recognizing the lack of realism in optimal replacement analyses that assume constant prices and yield patterns over time, a stochastic model appropriate to rubber production is developed. Data drawn from Peninsular Malaysia are used to implement the model. The results suggest that efforts should be directed towards establishing bench mark maximum annuities as guides to more economic replanting decisions rather than emphasizing earlier replanting per se. The significance of price stabilization policies also becomes evident.

Precision agriculture is one of the important agricultural technologies that can assist farmers and managers in promoting long-term success. Precision agriculture can help farm managers increase their management capacity, which is of utmost importance in the highly competitive modern agriculture. Increased yields and/or efficient input use can also be achieved with precision agriculture. Precision agriculture also involve a large capital outlay and requires skills in interpreting the masses of generated data. Modern farmers have to engage in pro-active thinking with regard to suitable agricultural systems that can enhance sustainable success of their farming businesses. Farm managers who are contemplating on getting involved in precision agriculture need...

This case study on the former Rice Growers Association (RGA) analyzes the effects of a variety of business decisions and market changes, relative to the ongoing Farmers’ Rice Cooperative (FRC). Interview and survey findings reveal that many respondents felt RGA’s Board of Directors was passive and, despite its large size, lacked the necessary expertise to direct management and represent the best interest of the broader cooperative membership. In the midst of challenging market conditions, RGA’s management teams were accused of making a number of poor business decisions that led to significant financial stress and the eventual dissolution of the firm.

A STUDY OF CEREAL PRICE INTERRELATIONSHIPS ACROSS MARKETS AND COMMODITIES AT THE WHOLESALE AND RETAIL LEVELS IN MALI
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Barry,   Abdoul Wahab.
Beginning in 1981, the government of Mali undertook several policy reforms to allow participation of private traders in cereal marketing, which up to that date was officially controlled by a parastatal.  These reforms can be expected to have an impact on the working of the cereals market.  One of the main objectives of this study is to assess the performance of the cereal marketing system.  The task is to study how different markets are interrelated in terms of price formation, by using wholesale and retail price data and different techniques of analysis.  These methods of analysis include bivariate correlations, calculation of margins, and multiple regression techniques.  Not only is the research aimed at showing the differences and similarities of the...

A STUDY OF RICE PRICES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kiet,   Nguyen Tang.
This paper tries to study rice price movements and relationships that might exist between rice prices of different selected countries; furthermore, some demand relations for rice will be constructed.  Factors influencing consumption such as changes in population and incomes will also be discussed.  The period under study will be from after the Second World War to 1960.  Rice price fluctuations can be observed from year to year both in local markets and in international trade.  This is due to differing demand and supply conditions.  On the one hand, production has greatly fluctuated, because of acreage and yield variations; on the other, rice consumption has changed patterns in many countries.

Burkina Faso is a landlocked country of the Sahel, bordered on the south by the Ivory Coast, Ghana, Togo and Benin, on the east by Niger, and on the northwest by Mali.  The climate of Burkina is primarily sudanian.  The country lacks mineral resources that can be exploited profitably with present technology.  Burkina economic progress depends primarily on the performance of its agricultural sector, which employs 80-90 percent of the population.  Crop cultivation is still the dominant activity in agriculture.    Cotton is the main export crop and a growing source of farmer income.  In Burkina Faso, cotton represented some 40 percent of the total recorded exports in recent years.  In view of the prominent position of cotton in the Burkina economy, the...

A Study on Technical Efficiency of Wheat Cultivation in Haryana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Singh,   Surender.
The farm-specific technical efficiency of wheat cultivation in Haryana at the aggregate and disaggregate levels has been studied using stochastic frontier approach. A high degree of technical inefficiency in wheat farming has been reported, which is due to factors under farm’s control. It has been argued that wheat-cultivating farms in the state can increase their production by 27 per cent without increasing the quantity of inputs, i.e. just by way of realizing efficiency. The estimates of technical efficiency have indicated that small-size farms are more efficient than medium- and large-size farms, negating thereby the myth that large-size farming is more profit/business-oriented.

Autores: White,   R. McKay; Veeman,   Michele M.
This paper reports on a review of literature in the form of academic papers and published research on ethical and consumer issues for GM crops in North America, with particular emphasis on GM wheat. The issues raised in these papers and the findings and arguments posed by the authors are outlined. A general conclusion that can be drawn from this overview is that public attitudes toward GM foods are diverse and sometimes quite strongly held. The strong negative views of GM food held by some appear to be mainly grounded in individuals’ ethical or moral values. Ethical and risk assessment issues have not been fully explored in the existing literature. There is a general consensus in the applied economics literature that GM crops result in economic benefits,...

Many florist crop producers have reported difficulty with attracting qualified employees to positions within their businesses. The purpose of this study was to define the difficulties florist crop producers face in attracting qualified workers. Managers of 72 florist crop production firms in Michigan, New York, Ohio, and Pennsylvania participated in a telephone survey designed to gather information on recruitment and selection issues for florist crop producers. The survey results revealed that recruitment practices were not used as frequently as they could be. It also appeared that managers were doing a better job with the selection process than they were with the recruitment process. In addition, compensation appeared to be closely linked to the ability...

Autores: Hlaszny,   Edit; Ladanyi,   Marta.
Aszőlő rügyfakadási időpontjának modellezése és előrejelzése növényvédelmi és gazdasági szempontból nélkülözhetetlen lépés a szőlőtermelésben. Tanulmányunkat öt fehérborszőlő-fajta (Chardonnay, Rajnai rizling, Hárslevelű, Pinot blanc és Szürkebarát), valamint ezek klónfajtáinak 2000 és 2004 között felvételezett adataival végeztük. Az ültetvények a Duna borrégión belül, a Kunsági borvidékhez tartozó Helvécián találhatóak. Számításainkhoz egy olyan matematikai modellt állítottunk fel, mely kis hibával megbecsüli a várható rügyfakadás napját. Amodell az általánosan használt kumulált hőösszegszámításon alapul, az optimalizálást pedig a becsült időpontok napokban számított hibájára végeztük. Az optimális bázishőmérsékletet 6 °C-ban állapítottuk meg. Amodell...

A Tale of Two Countries: Spatial and Temporal Patterns of Rice Productivity in China and Brazil
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: You,   Liangzhi.
This paper examines differences in the spatial and temporal variations of rice yields in China and Brazil. Our analysis indicates that, in China, rice yields have converged over time and rice production has become increasingly homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypothetical explanations may account for the different behaviors of rice yields in Brazil and China, namely: 1) differences in production systems (i.e. irrigated in China vs. upland in Brazil); 2) changes in rainfall patterns; and 3) bias in agricultural research and development (R&amp;D) towards irrigated rice. Our empirical analysis supports the first two hypotheses by establishing that: 1) upland rice...

Autores: Lencses,   Eniko.
A Szent István Egyetem Józsefmajori tangazdaságának relatív jó talajadottságokkal rendelkező tábláiban a precíziós tápanyagpótlás alkalmazásával akár hektáronként 60 kg nitrogénhatóanyag-megtakarítás is elvárható a konvencionális technológiához képest. A precíziós tápanyagpótlási technológiával, a vizsgált táblák 50%-ánál tapasztalható anyagköltség-megtakarítás. Az anyagmegtakarítás mellett célszerű számolni a működési költségek növekedésével. A Szegedi Gabonakutató Kft. segítségével végzett szántóföldi kísérletek adatai alapján megállapítható, hogy kukoricatermelésnél 48,85% őszi gyomborítottság felett ökonómiailag indokolt a precíziós gyomirtás.   -----------------------------------   By applying precision nutrient supplementation rather instead of...

Autores: Krewer,   Gerard; Fonsah,   Esendugue Greg; Boyhan,   George.
Tissue-culture propagated "Chicksaw" blackberry plants were set four feet apart in April of 2000 as part of a five-year trellising trial near Reidsville, Georgia. There were five treatments: an untrellised control, posts with plastic baling string on both sides, posts and three vertical wires, "raspberry" V trellis, and Limited Arm-Rotation Shift-Trellis (eliminated in 2003). There were four replications with twenty feet for each treatment per replication, for a total of 80 feet per treatment. Primocanes were tipped at 3.5 to four feet and re-tipped several times during the summer when new growth exceeded about 12 inches. Mature plant height at the end of the growing season was about five feet. Starting in the third growing season, yield data was collected...

A Unified Approach to the Estimation of Demand for Improved Seed in Developing Agriculture

Autores: Langyintuo,   Augustine S.; Hamazakaza,   Petan; Nawale,   Edah; Mekuria,   Mulugetta.
This paper proposes a new approach for estimating the demand for seed within a developing country context where only improved seeds are sold but adoption rates for improved varieties low. A farmer views an improved seed firstly as a derived input embodying production attributes and secondly, as a technology embodying consumption characteristics. He therefore jointly decides on its adoption and the quantity of seed required to plant a predetermined area. Drawing on the theory of demand for consumption goods characteristics and production input attributes, this paper specified and estimated non-separable household demand and consumption models using data collected from 300 farm households in Zambia during the 2003/04 crop season. The estimated results...

A Value Chain Task Force Approach for Managing Private-Public Partnerships:  Zamiba’s Task Force on Acceleration of Cassava Utilization.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chitundu,   Maureen; Droppelmann,   Klaus; Haggblade,   Steven.
Smallholder farmers operate in vertical supply chains. Therefore, an understanding of key opportunities and constraints up through the value chain becomes necessary for sustaining smallholder growth. Yet market analysis is of little value unless key private and public sector stakeholders agree to implement necessary reforms. This paper advocates an approach which marries together value chain analysis with a stakeholder taskforce to ensure that analysis of opportunities and constraints gets translated into actions that will facilitate commercial growth. Using Zambia’s cassava task force as an example, the paper describes the value chain task force method and identifies elements critical to its effective implementation.

Autores: Grimm,   Sadi S.; Paris,   Quirino; Williams,   William A.
The century-old “law of the minimum” proposed by von Liebig was tested using five independent sets of crop response data on wheat, corn, cotton, silage, and sugar beets. The rival models were polynomial functions reported in the literature as the most suitable models for interpreting those data. Overall, the von Liebig model performed very well. While the nonnested hypothesis test was inconclusive with regard to silage and sugar beets, the von Liebig model rejected the polynomial specifications for wheat, corn and cotton.

Access Issues for Plant Breeders in an Increasingly Privatized World
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lindner,   Robert K.
There is a growing trend to widespread privatisation of crop breeding, and there are grounds for expecting this trend to continue and even to accelerate. Possible consequences for Australian grain growers and the national interest of much greater private sector involvement in plant breeding are explored. Growing privatisation and commercialisation of plant breeding will lead to increased competition between plant breeders. While this increased competition has been at least partly driven by the potential for value creation, it also is likely to enhance value creation from plant breeding so long as there is adequate continuing investment in the capacity for plant breeding, and more particularly in productivity enhancing enabling technology. In the event of...

Access to Dynamic Markets for Small Commercial Farmers: The Case of Potato Production in the Peruvian Andes
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Escobal D'Angelo,   Javier; Torero,   Maximo.
The study has evaluated which are the most relevant factors that determine that a small farmer switch marketing channels in order to enter into a "dynamic" market; that is, into a market signed by more complex contractual relationships that can absorb increasing amounts of its output. The results show that there are a number of producers that currently are not selling to those markets but they may well do so. Restrictions associated to the degree of organization of the producers, their perception of risk and credit market restrictions may prevent these farmers to gain access to the additional benefits that these new market opportunities have to offer.

Access to Microfinance: Does it Matter for Profit Efficiency Among Small Scale Rice Farmers in Bangladesh?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sumelius,   John; Islam,   K.M. Zahidul; Sipilainen,   Timo.
This paper measures profit efficiency and examines the effect of access to microfinance on the performance of rice firms in Bangladesh. An extended Cobb-Douglas stochastic frontier profit function was used to assess profit efficiency and profit loss of rice farmers in Bangladesh in a survey data of 360 farms throughout the 2008-2009 growing seasons. Model diagnostics reveal that serious selection bias exists that justifies the uses of sample selection model in stochastic frontier models. After effectively correcting for selectivity bias, the mean profit efficiency of the microfinance borrowers and non-borrowers were estimated at 68% and 52% respectively, thereby suggesting that a considerable share of profits were lost due to profit inefficiencies in rice...

ACCESSING SEED THROUGH SHARECROPPING:  A RISK-SHARING STRATEGY FOR ANDEAN FARMERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Godtland,   Erin; Sadoulet,   Elisabeth; de Janvry,   Alain; Murgai,   Rinku.
In the Northern Andes, one of the riskiest agriculture climates in the world, farmers use sharecropping to obtain seed, their most costly input.  With survey data from Peru, this paper calculates that the cost of seed, when it is provided though sharecropping, is two times higher than the market price.  We test the hypothesis that risk-averse farmers are willing to pay more to receive seed through sharecropping because the contract provides implicit crop insurance.

Accounting for agronomic rotations in crop production: A theoretical investigation and an empirical modeling framework
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carpentier,   Alain; Gohin,   Alexandre; Letort,   Elodie.
As far as crop acreage choices are concerned, a consensus seems to exist among agricultural scientists and extension agents: crop rotation effects and the related constraints are major determinants of farmers’ crop choices. Crop rotation effects are inherently dynamic. They are generally ignored in multicrop models with land as an allocable input found in the literature since most of these models are developed within a static framework. The aim of this paper is twofold (i) to propose a new approach and tools for investigating dynamic crop acreage choices accounting for crop rotation benefits and constraints and (ii) to illustrate the impacts of crop rotation effects and constraints on farmers’ acreage choices through simulation examples. The models...

Autores: Molden,   David J.
This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and  increasing water...

Accuracy and Asymmetry of Corn, Soybean and Wheat Interval Forecasts
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Isengildina-Massa,   Olga; Sharp,   Julia L.; Zhang,   Jing; Campbell,   Wallace A.
This study evaluates the accuracy of USDA interval forecasts for corn, soybean, and wheat prices using Christoffersen’s (1998) tests for unconditional coverage, independence and conditional coverage adjusted for asymmetries in tail probabilities. The findings of this study demonstrate that due to uneven distribution of forecast misses around the interval, calibration of soybean price forecasts in several cases was rejected by basic coverage tests (suitable for symmetric intervals) but not rejected by the tests adjusted for asymmetry. Thus these forecasts were asymmetric but accurate. Symmetry was not a limiting assumption for corn and wheat interval forecast accuracy.

ACIAR’s 25 year investment in fruit-fly research
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lindner,   Robert K.; McLeod,   Paul.
Fruit flies are recognised as one of the major pests of fruit and vegetable crops worldwide. Potential benefits from fruit fly research include biosecurity benefits from better quarantine surveillance that reduces the costs of an incursion by a damaging exotic pest fruit fly; market access benefits by enabling new fruit exports; and field control benefits from better crop management. The Australian Centre for International Agricultural Research (ACIAR)’s investment in fruitfly research goes back some 25 years to an initial project in Malaysia. Since that time, ACIAR’s continued investment has funded a total of 18 projects ranging across several areas of fruit-fly research, and covering Malaysia, Thailand, Philippines, Fiji Islands, Samoa, Tonga, Cook...

Acreage Allocation Model Estimation and Policy Evaluations for Major Crops in Turkey
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Koc,   A. Ali.
This study estimates a system of supply equations for major field crops in Turkey and evaluates alternative agricultural policies for crop supply control. The supply of major field crops in Turkey responds significantly to both own-price and substitute price changes. The Turkish wheat price or gross return is the most important factor determining area allocation in Turkish field crops. Moreover, adopting measures that improve the growth of wheat yields also affect the substitute crops supply unless the price or gross return ratio is readjusted between substitute crops.

ACREAGE EFFECTS OF DECOUPLED PROGRAMS AT THE EXTENSIVE MARGIN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Goodwin,   Barry K.; Mishra,   Ashok K.
This analysis utilizes farm-level data to evaluate the extent to which U.S. farm program benefits, particularly the Agricultural Market Transition Act (AMTA) and market loss assistance payments, bring about distortions in production for wheat and barley production in the Northern Great Plains. The issue is important in light of the upcoming WTO negotiations and debate over the distortionary effects of such decoupled ("green-box") payments. Our results suggest that a modest, though statistically significant effect on acreage may have been evoked by AMTA payments. In particular,if the over $45 billion allocated to AMTA payments and market loss assistance had been doubled, wheat acreage may have been 7% greater and barley acreage may have been 12.8% higher....

ACREAGE PLANTING DECISION ANALYSIS OF SOUTH CAROLINA TOMATOES: NERLOVIAN VERSUS JUST RISK MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fu,   Tsu-Tan; Fletcher,   Stanley M.; Epperson,   James E.
Factors which explain supply response behavior of South Carolina tomato growers were determined. Two well known supply response models were used for comparison: the Nerlovian structural model and the Just risk model. The Just risk model reflected the significance of the risk effect in both stable and unstable periods. An evaluation of forecasting power between the two models was indeterminate. Growers are apparently willing to invest in more information with increased market instability because growers were influenced by the Florida winter price of tomatoes in planting decisions during the period of instability.

ACREAGE RESPONSE, EXPECTED PRICE FUNCTIONS, AND ENDOGENOUS PRICE EXPECTATIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Choi,   Jung-Sup; Helmberger,   Peter G.
Taking the price of futures as a proxy for expected price, this article treats acreage planted to soybean, the price of futures, and other variables as jointly dependent. A futures price equation is embedded in a simultaneous equations model along with the consumption demand and acreage response. The model is estimated using both ordinary and three-stage least squares. Estimated price elasticities for consumption demand, demand for stocks, and acreage response equal, respectively, -.5, -1.8, and +.2 (short run) and +.59 (long run).

ACREAGE RESPONSE UNDER FARM PROGRAMS FOR MAJOR SOUTHEASTERN FIELD CROPS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Duffy,   Patricia A.; Shalishali,   Kasazi; Kinnucan,   Henry W.
An expected utility model that includes output price and yield uncertainty was used to estimate cotton, corn, and soybean acreage response equations for the Southeast.  The model appeared to fit the soybean and corn data well, resulting in own-price elasticity estimates of 0.317 for corn and 0.727 for soybeans.  When applied to cotton acreage, however, the model did not yield satisfactory results. When elasticity was allowed to change over time, however, statistical results for the cotton equation improved, yielding an own-price elasticity of 0.915 at data means.

ACREAGE RESPONSES TO EXPECTED REVENUES AND PRICE RISK FOR MINOR OILSEEDS AND PROGRAM CROPS IN THE NORTHERN PLAINS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Krause,   Mark A.; Koo,   Won W.
Wheat, barely, flaxseed, and oilseed sunflower acreage respond to different economic variables. Wheat and barely acreage must be divided among program-complying, program-planted, and nonprogram-planted acreage because these categories respond to different variables and respond to own expected-revenue and price-risk variables in opposite ways. Flaxseed, sunflower, and nonprogram-planted acreage of wheat and barley have highly significant, positive responses to their own expected revenue and negative responses to their own-price risk. Flaxseed and sunflower acreage have been more responsive to their lagged values than to expected revenues for wheat.

Actuarial Impacts of Loss Cost Ratio Ratemaking in U.S. Crop Insurance Programs
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Woodard,   Joshua D.; Sherrick,   Bruce J.; Schnitkey,   Gary D.
This study examines the actuarial implications of the loss cost ratio (LCR) ratemaking methodology employed by the Risk Management Agency as a component of base rates for U.S. crop insurance programs, and identifies specific conditions required for the LCR methodology to result in unbiased rates when liabilities trend. Specifically, constant relative yield risk resulting in growing absolute variance through time and other restrictive requirements are required for the LCR to result in unbiased rates. These requirements are tested against a large farm-level data set for Illinois corn. Our findings indicate that the conditions required for appropriate use of the LCR methodology are violated for this high premium volume market, resulting in large implied rate...

ADAPTATION OF MEDITERRANEAN CROPS TO WATER PRESSURE IN THE EBRO BASIN: A WATER EFFICIENCY INDEX
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fernandez-Haddad,   Zaira; Quiroga,   Sonia.
In this paper, we assess the output-oriented technical efficiency of agricultural production functions in order to compare, over time, economic and environmental production processes in the different regions of the Spanish Ebro basin, in a climate change context. The measurement of technical efficiency in agriculture can provide useful information about the competitiveness of farms and their potential to increase its productivity moreover can help in the crops adaptation to water pressure by improving the management of scarce resources. Here, we generate an agricultural water efficiency index to evaluate the adaptation of some Mediterranean crops to the water pressures in this area. We estimate frontier production functions and technical efficiency...

Adapting agriculture to climate change
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Iglesias,   Ana; Quiroga,   Sonia; Diz,   Agustin; Garrote,   Luis.
We evaluate the potential impacts and measure the potential limits of adaptation of agriculture to climate change. Pressures on land and water resources are expected to intensify existing risks in low latitude areas – e.g., South-East Asia deltas – and in regions with current water scarcity – e.g. Mediterranean, and create new opportunities in some northern temperate areas – e.g., Northern Russia, Northern Europe. The need to respond to these risks and opportunities is addressed by evaluating the costs and benefits of a number of technical and policy actions. The discussion aims to assist stakeholders facing the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.

ADDITIVE VERSUS PROPORTIONAL PEST DAMAGE FUNCTIONS: WHY ECOLOGY MATTERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mitchell,   Paul D.
Economic analyses of pests typically assume damage is either additively separable from pest free yield or proportional to it.  This paper describes the ecological assumptions required for additive and proportional damage functions to demonstrate that both specifications are reasonable.  Ecological research supports a proportional damage function for competitive pests such as weeds, while for insect pests the appropriate damage function depends on the level of pest free yield.  Theoretical analysis identifies differences between additive and proportional damage functions in terms of the impact of pest control on output variance and the concavity of output in the pest control input.

Adjustment in Mexico's Crop Sector to Some Policy Changes Implemented in the 1990's
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dewbre,   Joe.
This paper contains analysis of potential effects of changes in the structure of farm support resulting from policy change in Mexico undertaken over the period 1989 to 2002. The analysis is based on observed changes in the level and composition of support as measured for the PSE. This information is used together with a model of Mexico’'s crop sector, the PEM, to derive predictions of policy effects and their implications for adjustment. These predictions are then compared with data revealing trends in crop production, yields, farm employment and purchased input use. The paper concludes that policy changes were a significant contributory factor to crop sector adjustment, but that other factors must have been at play as well.

Adjustment of Wheat Production to Market Reform in Egypt
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kherallah,   Mylene; Minot,   Nicholas; Gruhn,   Peter.
In response to slow growth in the agricultural sector and as part of a general shift towards a more market-oriented economy, the Government of Egypt started liberalizing the agricultural sector in 1987. Controls over wheat production and marketing were eliminated and wheat producer prices were brought closer to international levels. As a result, there has been remarkable increases in wheat crop area and yields, causing wheat production to triple from 1986 to 1998. This study analyzes the results of a survey of 800 Egyptian wheat farmers in order to address three issues that are of interest to agricultural reform policy in Egypt. First, what are the patterns in wheat production and marketing that have emerged following the economic reforms? Second, why is...

Technology adoption in precision agriculture has received considerable attention, while abandonment has received little. Our objective was to identify factors motivating adoption and abandonment of precision soil sampling in cotton. Results indicate younger producers who farmed more cotton area, owned more of their cropland, planted more non-cotton area, used a computer, or used a Personal Digital Assistant (PDA) were more likely to adopt precision soil sampling. Those with more cotton area or who owned livestock were more likely to abandon, while those who used precision soil sampling longer, used a PDA, or used variable-rate fertilizer application were less likely to abandon.

Adoption and diffusion of no tillage practices in Southern Spain olive groves
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Franco,   Juan Agustin; Calatrava-Requena,   Javier.
This paper analyses the process of adoption of no tillage in South-eastern Spain’s olive groves. Olive tree groves in South-eastern Spain’s mountainous areas are subject to a high risk of soil erosion, which is the main environmental problem for this crop, and have to incur in high costs of soil conservation. This results in a greater difficulty to comply with the practices required to benefit from both the single payment and agri-environmental schemes. In many high-steeped areas, farmers have opted for non-tillage practices as an alternative to other conservation practices. Using our own data from a survey carried out in 2006 among 215 olive tree farmers from the Granada Province in Southern Spain regarding the adoption of soil conservation and management...

Adoption and Impact of Hybrid Wheat in India
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Matuschke,   Ira; Qaim,   Matin.
In the light of ongoing debates about the suitability of hybrid seeds for smallholder farmers, this paper analyzes the adoption and impact of hybrid wheat in India. Based on survey data we show that farmers can benefit significantly from the proprietary technology. Neither farm size nor the subsistence level influence the adoption decision, but access to information and credit matters. Moreover, willingness-to-pay analysis reveals that adoption levels would be higher if seed prices were reduced. Given decreasing public support to agricultural research, policies should be targeted at reducing institutional constraints, to ensure that resource-poor farmers are not bypassed by private sector innovations.

Adoption and impacts of zero tillage as a resource conserving technology in the irrigated plains of South Asia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Erenstein,   Olaf; Farooq,   Umar; Malik,   R.K.; Sharif,   Muhammad.
The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource-conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State (34.5% of surveyed households) and Pakistan’s Punjab province (19%). The combination of a significant “yield effect” and “cost-saving effect” makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat...

This study documents the adoption and impacts of zero-tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State primarily drawing on a detailed empirical survey of 400 rice-wheat farmers. Our random stratified sample revealed 34.5% to be ZT wheat adopters and a quarter of the wheat area in the surveyed communities to be under ZT. The study suggests the potential for further diffusion but also flags the issue of disadoption (10%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values. ZT drastically reduces tractor operations in farmers’ ZT wheat fields from an average of 8 passes to a single pass, implying a saving of 6 tractor hours and 36...

Adoption and Use of Improved Maize by Small-Scale Farmers in Southeast Guatemala
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sain,   Gustavo; Martinez,   Julio.
This report is based on a study of the adoption and use of improved open-pollinated varieties and hybrids by small-scale farmers in the Department of Jutiapa, Guatemala. The majority of maize producers in Guatemala are small-scale subsistence farmers. Approximately 60% of the basic grains produced in the country are grown on farms that are too small to satisfy the basic nutritional needs of a typical family (5-6 persons). Increasing yields through the use of new technologies is seen as a critical step to ensuring adequate nutrition and increasing farmer income in the area. The study, conducted in June and July 1991, randomly surveyed 208 farmers in 18 municipalities of Jutiapa, apportioned according to the number of farms in each municipality. There was...

Autores: Mignouna,   D.B.; Mutabazi,   K.D.S.; Senkondo,   E.M.; Manyong,   Victor M.
Declining yields of maize as a result of Striga infestation has necessitated a new technology known as Imazapyr-resistant maize (IRM) to contain the problem. As a result, research and development initiatives with substantial participation of the private sector to transfer this new technology to farmers have been made in western Kenya. This study therefore assesses the adoption of IRM variety and efficiency levels of farmers in western Kenya. A multi-stage sampling technique was used to select a total of 600 households from Nyanza and Western provinces for this study. Tobit model and stochastic production frontier analysis were the analytical methods. Results show that age, education, maize production gap, risk, contact with extension agents, lack of seeds,...

This study examined adoption of ten best management practices (BMPs) to control weed resistance to herbicides. Using data from a survey of 1,205 U.S. cotton, corn, and soybean growers, count data models were estimated to explain the total number of practices frequently adopted. Ordered probit regressions were used to explain the frequency of individual BMP adoption. Growers practicing a greater number of BMPs frequently (a) had more education, but less farming experience; (b) grew cotton, (c) expected higher yields relative to the county average; and (d) farmed in counties with a lower coefficient of variation (CV) for yield of their primary crop. Yield expectations and variability were significant predictors of the frequency of adoption of individual...

Autores: Fernandez-Cornejo,   Jorge; McBride,   William D.
Use of crop biotechnology products, such as genetically engineered (GE) crops with input traits for pest management, has risen dramatically since commercial approval in the mid-1990s. This report addresses several of the economic dimensions regarding farmer adoption of bioengineered crops, including herbicidetolerant and insect-resistant varieties. In particular, the report examines: (1) the extent of adoption of bioengineered crops, their diffusion path, and expected adoption rates over the next few years; (2) factors affecting the adoption of bioengineered crops; and (3) farm-level impacts of the adoption of bioengineered crops. Data used in the analysis are mostly from USDA surveys.

With increasing environmental concerns, increasing population, changing tastes and preferences of consumers towards healthier foods, and with more food safety requirements, agronomic practices have changed gradually to provide not only food and fiber but also public goods and other beneficial services from agriculture. Cover cropping is one type of technology increasingly being adopted by producers of multifunctional agriculture. Cover crops provide a range of benefits, both private and public. In this paper we identify factors affecting farmers’ choice to adopt cover crops. We examine the impact on nitrogen use from adopting cover crops and the resultant decrease in input costs.

ADOPTION OF DOUBLE-CROPPING SOYBEANS AND WHEAT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shapiro,   Barry Ira; Brorsen,   B. Wade; Doster,   D. Howard.
Double-cropping of soybeans and wheat is often promoted by extension personnel.  This paper seeks to explain how the decision to adopt double-cropping is made, using a Tobit regression model.  Tobit makes use of more of the information in the data set than do logit or probit and explains not only the decision to double-crop but also the rate of adoption.  The paper considers factors such as profit and risk perceptions and risk which have not been included in the past models used to explain adoption of technology.  The results show that risk perception is important.  Contrary to the findings of some other adoption studies, this decision is not influenced by human capital factors.  The farmers who double-crop are more highly leveraged and appear to do so...

The adoption of environmental management practices is addressed in this paper. The use of consumer behaviour theory and a market research approach is discussed by describing how it was used in the study. Qualitative methods were used to gather data from dairy farmers in four New Zealand catchments. The environmental practices explored were; excluding stock from waterways, reducing phosphorus use, improving soil macroporosity, managing effluent and improving the efficiency of border-dyke irrigation. The findings are discussed, highlighting that farm contextual factors influenced farmers’ decision making in terms of adopting environmental management practices. The results suggest that environmental practices need to be linked to farm context. This should...

Enhanced agriculture productivity in sub-Saharan Africa is critical to promote economic growth and poverty alleviation and to avoid increasing food scarcities in the region. The impact of commercialization and intensification of agriculture on the well- being of the rural poor depends on how they are carried out. Past research by IFPRI and collaborating institutions on commercialization of small- scale farming in about a dozen countries provided new knowledge about the relationships between commercialization and rural well- being as measured by incomes, consumption, and nutrition. These links were shown to depend greatly on household behavior, which in turn is influenced by intrahousehold processes. A better understanding of these processes is likely to...

Adoption of Integrated Pest Management Practices in Paddy and Cotton: A Case Study in Haryana and Punjab
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Singh,   Alka; Vasisht,   A.K.; Kumar,   Ranjit; Das,   D.K.
The study has examined the adoption of IPM practices on cotton in Punjab and on paddy in Haryana and has assessed the impact of key socio-economic and institutional factors on IPM adoption. The Poisson count regression models have been used to analyze technology adoption. The awareness generation about technology through formal crop-specific IPM training provided by the farmers’ field schools has been found extremely effective in wider adoption of IPM in the study areas. Hence, investment in IPM education through these programmes will have long-term beneficial impact. Regarding effectiveness of extension services, the study has not shown (frequency of meeting extension personnel) any statistically significant impact on IPM adoption rates. Mixed evidence...

Adoption of Maize Conservation Tillage in Azuero, Panama
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: de Herrera,   Adys Pereira; Sain,   Gustavo.
An aggressive research and validation program launched in 1984 in Azuero, Panama, yielded a recommendation advocating zero tillage for maize production. Ten years later, maize farmers in Azuero used three land preparation methods: conventional tillage, zero tillage, and minimum tillage (an adaptation of the zero tillage technology). This study aimed to quantify the adoption of zero and minimum tillage for maize in Azuero; identify factors influencing adoption of the different land preparation practices; and analyze the implications of the findings for future maize research and extension. Between 1985 and 1994, farmers in Region I of Azuero changed from conventional tillage to zero (33%) and minimum tillage (43%). In Regions II and III, most farmers still...

Autores: Wekesa,   E.; Mwangi,   Wilfred; Verkuijl,   Hugo; Danda,   Milton Kengo; De Groote,   Hugo.
Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers...

Adoption of New Seed Varieties Under Production Risk: An Application to Rice in Iran
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bakhshoodeh,   Mohamad; Shajari,   S.
This paper focuses on linkage between new rice seed varieties and production risk and also factors affecting adoption of these varieties in Iran. Farm-level data were collected from a sample of 154 rice farms located in two major districts of Fars province in Southern Iran for 2001-02. The risk-premium associated with the use of seed is estimated following by analyzing a moment-based production risk approach. The results show that the risk premium increases with new seed varieties in the lack of appropriate production conditions implying that new seed varieties is a riskincreasing input and involves a higher cost of risk. However, under suitable production conditions, the cultivation of new rice varieties on average ensures greater yield and at the same...

Adoption of Soil Erosion Control Practices in Southern Spain Olive Groves
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Franco,   Juan Agustin; Calatrava-Leyva,   Javier.
This paper presents results from a survey carried out in 2005 among 147 olive tree farmers from the Alto Genil River Basin in Southern Spain regarding the adoption of soil conservation and management practices. Olive tree groves in South-eastern Spain's mountainous areas are subject to a high risk of soil erosion and have to incur in high costs of soil conservation. This results in great difficulties to comply with cross-compliance and to benefit from agri-environmental schemes. Our main objectives are to analyse the current level of adoption of soil conservation practices and to analyse which socio-economic and institutional factors determine such adoption. Three Probit models are estimated. Dependant variables are three different soil conservation...

A nested logit model was used to analyze the 2009 Southern Cotton Precision Farming Survey to study the impact of farmer and farm characteristics on the adoption of Variability Detection Technologies (VDT) and the adoption of Variability Rate application Technology (VRT) conditioned on the type of the VDT chosen.  The results showed that the farm size and exposure to extension activities are important factors affecting the choice of VDTs.  The farmers adopting both soil and plant based VDTs are more likely to adopt VRT.  The probability of adoption of VRTs was lower for Texas cotton farmers irrespective of the type of VDT adopted.  In general, younger, more educated farmers who use computers for farming operations are more likely to adopt VRT when they...

We analyze the presence and potential impact of low quality fertilizers, inadequate access to credit and market information on fertilizer market participation and application rates. We explain in theory and show empirically that farmers chose to abstain from the fertilizer market altogether or decrease their application rates below recommended levels because bad quality deters all buyers not willing to pay the market price for the average quality fertilizer available.

Aerobic Rice: Benefits without going to the Gym?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bayot,   Ruvicyn; Templeton,   Deborah J.
Rice, a staple food for over 70% of Asians, is also the single biggest user of water, requiring 2‐3 times more water per unit of grain produced than crops such as wheat and maize. With growing populations, increased urbanisation and environmental degradation, the supply of fresh water is depleting. Recognising the water constraints to rice yield, the aim of the project entitled ‘Developing a System of Temperate and Tropical Aerobic Rice (STAR) in Asia’ was to develop water‐efficient aerobic rice technologies. This paper highlights the success of that project.

The Agricultural &amp; Food Policy Center (AFPC) updated the comparison of corn and sorghum county loan rates following the general methodology outlined in the October 2002 Food and Agricultural Policy Research Institute (FAPRI) study on corn and sorghum loan rates. The study answers two questions: 1. Are the 2006 county loan rates established by USDA consistent with the Congressional mandate that national average loan rates for both commodities be $1.95 per bushel? 2. What would be the impact if USDA were to adopt a different weighting scheme in setting county loan rates while continuing to maintain the mandated national average loan rate? Specifically, what would be the impact on sorghum loan rates if each county’s loan rate were weighted by the county’s...

Aggregate and Farm-level Productivity Growth in Tobacco: Before and After the Quota Buyout
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kirwan,   Barrett E.; White,   T. Kirk; Uchida,   Shinsuke.
We examine the distortionary effects of agricultural policy on farm productivity by examining the response of U.S. tobacco farmers' productivity to the quota buyout of 2004. We isolate the impact of distortionary policy, i.e., the tobacco quota, by decomposing aggregate productivity growth into the contribution of farm-level productivity growth and the contribution of reallocation of resources among tobacco growers. Reallocation of resources includes entry into and exit from tobacco farming, as well as growth or decline of the resources allocated to existing tobacco farms. We find that aggregate productivity of Kentucky tobacco farms grew 37% between 2002 and 2007.  Reallocation of resources among continuing tobacco farms contributed 22 percentage points...

Aggregate eco-efficiency indices for New Zealand – a Principal Components Analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jollands,   Nigel; Lermit,   Jonathan; Patterson,   Murray.
Eco-efficiency has emerged as a management response to waste issues associated with current production processes. Despite the popularity of the term in both business and government circles, limited attention has been paid to measuring and reporting eco-efficiency to government policy makers. Aggregate measures of eco-efficiency are needed, to complement existing measures and to help highlight important patterns in eco-efficiency data. This paper aims to develop aggregate measures of eco-efficiency for use by policy makers. Specifically, this paper provides a unique analysis by applying principal components analysis (PCA) to eco-efficiency indicators in New Zealand. This study reveals that New Zealand's overall eco-efficiency improved for two out of the...

AGGREGATION ISSUES IN PEST CONTROL ECONOMICS: A BIOECONOMIC APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Young,   Douglas L.; Smith,   Elwin G.; Kwon,   Tae-Jin.
Previous research has defined “aggregate pesticide expenditures” as the control variable; however, virtually all managerial recommendations and environmental restrictions target specific pesticides, rates, and crops. A bioeconomic approach considering particular pesticides on specific pests and crops is recommended for managerial-policy applications and testing for increasing returns. Exponential weed control and seven popular yield damage functional forms were estimated for a bioeconomic weed control model for winter wheat in Washington. Concavity with respect to herbicide rate was observed for most popular damage functions at normal weed densities and manufacturers’ label rates, but convexity existed outside these ranges and should be checked.

Agricultural Arbitrage, Adjustment Costs, and the Intensive Margin
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tack,   Jesse B.; LaFrance,   Jeffrey T.
Farmland and capital are an important and rapidly expanding component of the agricultural economy, and empirical evidence suggests that these assets are quasi-fixed in that adjustment costs are incurred when holdings are altered. Increased interest in the rate of return for investing in farmland suggests that an important consideration is the effect of adjustment costs on this return. A novel theoretical model is developed that ties together contributions from the farmland pricing and adjustment cost literatures, and the first order conditions for a utility maximizing decision maker are rearranged into intertemporal arbitrage equations that are similar in spirit to traditional finance models. The common assumptions that land and capital are quasi-fixed...

Agriculture is to a large part responsible for nitrate leaching into groundwater and rivers in Germany, especially in highly intensive agricultural regions. To evaluate the link between nitrogen surpluses from agriculture and nutrient leaching into ground- and surface waters, a model network to analyse current and future nitrogen surplus developments and water quality is set up by connecting hydrological and hydrogeological models with the German agricultural sector model RAUMIS. A set of different environmental measures and their costs is selected to fulfil surface and groundwater targets of the European water framework directive (WFD) for the case of the Weser River basin. Results show that with additional agri-environmental measures covering around 1...

AGRICULTURAL DIVERSIFICATION IN INDIA AND ROLE OF URBANIZATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rao,   P. Parthasarathy; Birthal,   Pratap Singh; Joshi,   P.K.; Kar,   D.
Indian agriculture is diversifying during the last two decades towards High-Value Commodities (HVCs) i.e., fruits, vegetables, milk, meat, and fish products. The pace has been accelerated during the decade of 1990s. HVCs account for a large share in the total value of agricultural production. Supply and demand side factors coupled with infrastructural development and innovative institutions drive these changes. In this paper, the focus is on diversification towards HVCs in the context of urbanization. Group of urban districts (districts with &gt;1.5 million urban population) have a higher share of HVCs compared to the urban-surrounded (near urban districts) and other districts (districts in the hinterland). Among the HVCs, vegetables and meat products have...

Agricultural Efficiency Gains and Trade Liberalization in Sudan
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Siddig,   Khalid H.A.; Babiker,   Babiker Idris.
The traditional agriculture in Sudan occupies 60% of the total cultivated land and employs 65% of the agricultural population. Nevertheless, it is characterized by its low crop productivity, which is mainly driven by low technical efficiency, while drought and civil conflicts threaten most of its areas countrywide.  Therefore, it has contributed only an average of 16% to the total agricultural GDP during the last decade. This paper addresses from an empirical point of view the sectoral and macroeconomic implications of agricultural efficiency improvement in Sudan and assesses the efficiency gains under the assumption of trade liberalization. Efficiency improvement experiments are implemented by augmenting the efficiency parameters of labor, capital, and...

Autores: Saunders,   Caroline M.; Kaye-Blake,   William; Campbell,   Rachel; Benge,   J.
Agri-environmental indicators (AEIs) developed by the OECD have been used to assess the environmental performance of the agricultural sector in developed countries. The Agricultural Research Group on Sustainability (ARGOS) in New Zealand has investigated using these AEIs to assess the performance of individual kiwifruit orchards. ARGOS is following panels of orchards to investigate the impacts of organic and conventional management systems on economic, sociological, and environmental dimensions of farming. The environmental monitoring of these orchards has provided data for calculating AEIs. The paper discusses the performance of ARGOS orchards, the impact of management systems, and the implications for future research.

This paper examines how the fertilizer sector in general, and farmers’ demand for  fertilizer in particular, has evolved since the introduction of fertilizer sector reforms in  Ethiopia. There is much debate in the agricultural development literature about whether fertilizer  use in Africa is constrained primarily by poor input distribution systems, by farmers’ lack of  knowledge concerning the benefits and correct use of fertilizer, or by lack of effective demand  because the product is simply not profitable enough. This paper looks at each of these issues in  an effort to understand the relative importance of the different constraints and how well current  policies are addressing the problems. It attempts to identify additional policy measures needed  to...

Agricultural Policy Adjustments in East Asia: The Korean Rice Economy
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kwon,   Yong Dae; Yamauchi,   Hiroshi.
The processes of agricultural policy decision-making in the East Asian economies of Japan, Taiwan, and Korea are characterized by the complex interactions of competing special interest groups in their respective political arenas. An analytical model is designed to investigate how adjustments in rice price policies are endogenously related to the political economic forces associated with macroeconomic changes. The model is tested against the case of Korean rice price policy, which has not been satisfactorily explained in earlier modeling efforts. A political preference function is used to estimate the relative political weights of producers, consumers, and government over a 25-year period (1961-1985) during which major macroeconomic changes occurred.

Autores: Heikkila,   Jaakko; Peltola,   Jukka.
Changes in climatic and policy environments combined with uncertainty related to stochastic environmental fluctuations make design of invasive pest policy challenging. These external changes are often exacerbated by changes in the species characteristics. We discuss facing local change and uncertainty when deciding ex ante on a specific policy strategy. Our empirical case deals with an invasive agricultural pest, Colorado potato beetle, and agricultural production in Finland. Invasions are modelled as temporally random events and stochasticity in key variables is built into the analysis. The viability of two specific policy options is evaluated given uncertainty and local change.

Agricultural Research Impact Assessment: The Case of Maize Technology Adoption in Southern Mali
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Boughton,   Duncan; Frahan,   Bruno Henry de.
Adoption of the improved maize package was particularly rapid during the period 1980-86 when an attractive guaranteed price was offered and extension activities were reinforced by a maize project that included the establishment of a seed multiplication program. Following cereal market price liberalization in 1986, maize prices fell and have been subject to considerable variability. Area has continued to expand, but farmers have greatly reduced fertilizer use, switched back to maize-late millet intercropping, and substituted early maturing varieties better suited to their own food security needs. The estimated internal rate of return (IRR) to investment in maize research and extension in southern Mali over the period 1969-90 is 135%. This high rate can be...

Agricultural response analysis in a longer term framework
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Farquharson,   Robert J.; Cacho,   Oscar J.; Turpin,   J.E.
Issues of long term soil fertility decline and sustainability are becoming more important for cropping industries in Australia. Helping to manage the level of soil fertility in this context is an aim of economic response analysis. This paper reviews the theory and methods used by economists to derive the optimal level of an input to be used in a production process. In particular, response functions generated by a crop simulation model are used as a basis for the analysis. The use of such models is becoming widespread in the research and extension community. A variety of methods are presented, in increasing order of complexity, to account for the real world characteristics of the production environment in this context.

Agricultural Trade and Freshwater Resources
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Reimer,   Jeffrey J.
Approximately 75% of all water used by humans goes towards food production, much of which is traded internationally.  This study formally models how this works in the case of crop agriculture, making use of recent advances in international trade theory and new data on the productivity by which countries use water for crop agriculture.  The strength of the model lies in its ability to predict, when there is a shock to the system, how trade between pairs of specific countries changes for products that use water intensively.  In one application of the model, international trade in final products is shown to be a means for countries to deal with short- and long-run shocks to water resources that are too big for one country to handle by itself in isolation.  In...

Agricultural Trade Liberalisation and Economic Growth in Developing Countries: Analysis of Distributional Consequences
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ali,   Ershad; Talukder,   Dayal.
The article analyses the impact of agricultural trade liberalisation on economic growth as well as on the welfare of rural livelihoods in developing countries through technological transformation in the agricultural sector. The article, based on existing literature, considers the background and reasons for the policy shift in developing economies away from agricultural protection and toward trade liberalisation. It attempts to shed light on the debate over the distributional consequences resulting from trade liberalisation. It also analyses how agricultural trade policy reforms affect poverty and inequality, since the majority of the population of developing countries is involved with agriculture, and these households are predominantly rural poor and...

Agricultural Value Chain Development in West Africa – Methodological framework and case study of mango in Benin
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: van Melle,   Cathelijne; Coulibaly,   Ousmane; Hell,   Kerstin.
Globalization and competitiveness of agricultural commodities could have significant potential benefits for food security and poverty reduction in West Africa. Participation in global trade and economy is potentially important but not enough to ensure benefits at all levels of the chains and equitable distribution of income for each participant. Efficiency is key in the commodity value chain, but effective support functions and services, infrastructure, legal and policy environment are important. This paper presents the framework of value chain concept and analysis, as a guide to enhance competitiveness of commodities at national, regional or global level. The paper applies the value chain framework to a case study on mango in Benin, West Africa. The...

Agricultural yield expectations under climate change - a Bayesian approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Krause,   Jette.
In the years to come, German wheat, corn and aggregated cereal yields can be expected to show growing deviations from a linearly increasing trend. This results from the Bayesian Updating approach I apply to agricultural yield data. The updating procedure is carried out on a set of hypotheses on yield development, which are weighted in the light of yield data from 1950 through 2006. All hypotheses share the assumption of a linear yield trend with normally distributed variance of actual data from this trend, but differ in regard to possible future developments. The set of hypotheses allows for both the trend and the variance of data to stay unchanged, increase or decrease by 20 per cent from one period to the next. As a result, yield expectations converge to...

AGRI-ENVIRONMENTAL POLICIES IN A TRANSITIONAL ECONOMY: THE VALUE OF AGRICULTURAL BIODIVERSITY IN HUNGARIAN HOME GARDENS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Birol,   Ekin; Smale,   Melinda; Gyovai,   Agnes.
Agricultural biodiversity is an environmental resource. Much of the agricultural biodiversity remaining in situ today is found on the semi-subsistence farms of poorer countries and the small-scale farms or home gardens of more industrialized nations. The traditional small farms of Hungary are labelled "home gardens" as a reflection of their institutional identity during the collectivisation period. Homesteads managed with family labor, they continue to serve essential food security and diet quality functions during economic transition. Home gardens contribute to the preservation of rural settlements and cultural heritage, and they contain relatively high levels of several components of agricultural biodiversity. The role of home gardens in the...

Agro-well and pump diffusion in the dry zone of Sri Lanka:  Past trends, present status and future prospects
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kikuchi,   Masao; Weligamage,   Parakrama; Barker,   Randolph; Samad,   Madar; Kono,   Hiroichi; Somaratne,   H.M.
The use of shallow wells, equipped with small pumps, to lift groundwater has spread rapidly in many agricultural regions of tropical monsoonal Asia. In Sri Lanka, the rapid and pervasive invasion of agro-wells and pumps drew the attention of policymakers and researchers, but many questions were left unanswered due to lack of research in the area. This study aims to fill this gap in knowledge, based on observations and data obtained in field surveys conducted in major and minor irrigation schemes in the dry zone of Sri Lanka. This report gives the key findings of this study into the pattern, extent and causes of the spread and use of agro-wells and pumps in traditional villages and irrigated settlement schemes. It investigates farmer investments in...

AIR POLLUTION AND FARM-LEVEL CROP YIELDS: AN EMPIRICAL ANALYSIS OF CORN AND SOYBEANS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Westenbarger,   David A.; Frisvold,   George B.
While many studies have estimated the impacts of air pollution on crop yields on experimental plots, few have estimated these impacts under actual farm production conditions.  This study econometrically estimates the impact of air pollution on corn and soybean yields, controlling for weather, soil quality and management practices, using farm-level data for the eastern United States.  Ozone pollution was found to reduce yields for both crops.  The mean elasticity of yield with respect to ozone exposure was -0.19 for corn and -0.54 for soybeans.  The benefits of ozone standards to protect crops, measured in terms of crop revenues, range from $17 to $82 million depending on the stringency of the standard.  Over 85 percent of the revenue gains are captured by...

ALBERTA AGRICULTURE AND FOOD TRADE: RECENT TRENDS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rosario,   Joe A.
Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

ALERT:  FARMERS NEED TO SIGN UP FOR ACRE!
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hilker,   James H.; Betz,   Roger; Black,   J. Roy.
Corn, soybean and wheat producers are facing serious financial challenges. And it is even worse for livestock producers, most of who are also crop producers and are therefore eligible for ACRE.  Crops are behind in maturity, some areas of the state need rain, product prices have fallen substantially, and USDA Counter Cyclical payments do not start until $2.35 on corn, $5.36 soybeans and $3.40 on wheat. Chances of prices that low are around 10-15%, but at that point ACRE payments would be much, much bigger.  Many producers do not understand ACRE and the benefits available; most of the reasons given for not participating are invalid.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lal,   Padma; Lim-Applegate,   Hazel; Reddy,   Mahendra.
Since 1997, the agricultural leases on Native land, issued under the 1976 Agricultural and Landlord Tenants Act (ALTA), began to expire. The sugar industry is the main commodity export earner for Fiji, directly contributing about 22% of the national GDP and supporting over 25% of the country's active labor force. Fiji exports 80% of its sugar production, earning on average of $250-300 million in foreign exchange annually. Several options have been suggested, including: non-renewal of leases, with the land reverting to Fijian owners; renewal of ALTA but with land rents pegged to the gross value of production instead of the unimproved capital value; sharecropping and contract wage arrangements; and abolishment of lease arrangement under ALTA with leases to...

Three index-based crop insurance contracts are evaluated for representative south Georgia corn farms. The insurance contracts considered are based on indexes of historical county yields, yields predicted from a cooling degree-day production model, and yields predicted from a crop-simulation model. For some of the representative farms, the predicted yield index contracts provide yield risk protection comparable to the contract based on historical county yields, especially at lower levels of risk aversion. The impact of constraints on index insurance choice variables is considered and important interactions among constrained, conditionally optimized, choice variables are analyzed.

Coffee is the most important export crop in Uganda and an important source of income among smallholder farmers in large parts of the country. The Robusta type dominates coffee production and Ugandan Robusta is demanded by roasters as a component in certain blends due to its special taste qualities. However, a combination of events outside and within Uganda, especially the collapse of world coffee prices in the late 1990s, are eroding farmer incomes and export revenues and threaten the long-term viability of the industry. In this context, the paper first investigates the challenges faced by the Ugandan coffee industry, namely the decline in the world coffee market, changes in procurement strategies among coffee importers, the rapidly expanding market for...

Alternative Hedging Strategies in Maize Production to Cope with Climate Variability and Change
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fuhrer,   Jurg; Beniston,   Martin; Calanca,   Pierluigi; Torriani,   Daniele Simone.
Climate change with increasing climate variability is likely to alter risks in agricultural production. The effectiveness of using weather derivatives to hedge against drought risks for rain-fed grain maize production was investigated for current (1981-2003) and future (2070- 2100) climates in Switzerland. The climate change scenario was extrapolated from results of a regional climate model (HIRHAM4) based on the IPCC A2 emission scenario. In addition, a sensitivity analysis was performed by varying the mean and variance of the initial probability space for the seasonal precipitation sum. Profits and risks with and without hedging were compared using the analogy of the value-at-risk measure (VaR), i.e., a quantile-based measure of risk. A Monte Carlo chain...

Alternative Instruments for Ensuring Food Security and Price Stability in Zambia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dorosh,   Paul A.; Dradri,   Simon; Haggblade,   Steven.
Given heavy dependence on rainfed maize production, Zambia must routinely cope with pronounced production and consumption volatility in their primary food staple. Typical policy responses include increased food aid flows, government commercial imports and stock releases, and tight controls on private sector trade. This paper examines recent experience in Zambia, using a simple economic model to assess the likely impact of maize production shocks on the domestic maize price and on staple food consumption under alternative policy regimes. In addition to an array of public policy instruments, the analysis evaluates the quantitative impact of two key private sector responses in moderating food consumption volatility— private cross-border maize trade and...

America’s Organic Farmers Face Issues and Opportunities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Greene,   Catherine R.; Slattery,   Edward; McBride,   William D.
Organic agriculture has established a foothold in many U.S. farm sectors, particularly among horticultural specialties, but the overall use of organic practices lags behind that of many other countries. Recent data from several producer surveys illustrate notable differences and similarities between organic and conventional farmers. Emerging issues in the organic sector include dampened consumer demand resulting from the weaker U.S. economy and potential competition from new labels like the “locally grown” label.

An Agricultural Statistical Profile of Bangladesh, 1947-1999
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chowdhury,   Mohammad A.T.; Zulfikar,   Harry.
This is the seventh in the series of the Centre's publications providing specific and wide-ranging data on coarse grains, pulses, roots and tuber (CGPRT) crops in the humid tropics of Asia and the Pacific. The crop sub-sector dominates the agricultural scenario in Bangladesh. The greater uniformity of the landmass, the fertile alluvial soil and the tropical monsoon climate provide excellent conditions for crop production. If other things remain unchanged, agriculture will continue to play the main role in the growth and stability of the economy of Bangladesh for many years to come. This volume covers time-series statistics of Bangladesh on seventeen CGPRT crops plus two major cereals (rice and wheat) reporting area, production and yield at both national...

AN ANALYSIS AS TO THE CAUSAL RELATIONSHIP BETWEEN BIOETHANOL EXPANSION AND AGRICULTURAL CROP ACREAGE ALLOCATION IN THE UNITED STATES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lee,   Young-Jae; Kennedy,   P. Lynn.
This study analyzes the historical price response of individual crop acreage in order to determine the impacts of an expansionist policy in bioethanol production on the U.S. agricultural industry. In doing this, this study provides an economic foundation by using a traditional Rotterdam model to simulate a cropland demand system. Within the developed framework,  this study estimates own and cross acreage elasticities and scale elasticities to show the impacts of acreage values on crop production and the relationship between total cropland and individual crop acreage. This study found that rice farming is most inelastic to own acreage value. Soybeans, hay, and wheat are shown to be good substitute crops for corn. Corn, soybeans, hay, wheat, cotton, barley,...

An Analysis of Alternative Maize Marketing Policies in South Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jayne,   Thomas S.; Hajek,   Milan; van Zyl,   Johan.
The maize-oriented agricultural economies throughout Southern Africa are in fundamental transition. Increased recognition of the costs of historical controls on pricing and marketing already has led to partial maize market liberalization in several countries in the region. However, there is still intense debate over the appropriate scope and implementation of future food market reform. Much of the debate derives from uncertainty over the consequences of comprehensive and politically risky changes to domestic markets, especially at a time when regional market conditions are also in flux due to agricultural restructuring in neighboring countries. There is currently little information on the direction and magnitude of grain trade between South Africa,...

AN ANALYSIS OF CONSTRAINTS ON EXPANDING RICE OUTPUT IN THE CASAMANCE REGION OF SENEGAL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rigoulot,   Jean Pierre.
Senegal imports about 200,000 tons of rice annually.  These import consume a large share of the national budget and represent a heavy outflow of foreign exchange.  Despite the implementation of various agricultural projects aimed at increasing domestic rice production, Senegal still relies on imports to fill its deficit and there is no evidence that the situation will change in the near future. The purpose of this paper is to identify and analyze selected factors which are believed to impede expansion of rice production in the Casamance (southern) region of Senegal.  The following factors are studied:  1)  climatic uncertainties (effects of the drought); 2)  the competition between groundnuts and rice for the allocation of family labor; 3)  the...

Expansion of the cotton industry depends on economic growth. Models were specified to estimate U.S. domestic and export demand with and without structural change. The results indicate that domestic demand increases with per capita GDP and decreases with rising oil prices. U.S. export demand for cotton expands with lower beginning stocks in the rest of the world and rising per capita income.

An Analysis of Food Grain Consumption in Urban Jiangsu Province of China
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zheng,   Zhihao; Henneberry,   Shida Rastegari.
The impacts of economic and demographic variables on the demand for food grain commodities in urban Jiangsu province of China are estimated, using both the QUAIDS and the AIDS models. Results show that the demands for wheat flour and coarse grains are price-elastic while the demands for rice and grain products are price-inelastic. Certain demographic variables show as having a significant impact on food grain demand. Finally, a decomposition of causes of changes in rice consumption over the period of 1995–2007 is performed.

Autores: Jiao,   Hui.
This paper presents a quantitative analysis of the Chinese wheat and rice industries.  The specific purpose is to analyze government policies for wheat and rice, and their impacts on industry performance.  Dynamic relationships among prices, quantities and total GNP are investigated with a vector autoregression using Chinese data. Government intervention in domestic commodity markets is quite common in China.  The Chinese government is not only heavily involved in production, but also in marketing and distribution of most commodities, especially agricultural products.  Production planning and collection rationing are used to reduce the need for food imports.  Grain price policy is used as an economic tool to promote the government's objectives of...

AN ANALYSIS OF RICE SUPPLY AND DEMAND IN THE IVORY COAST
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Coulibaly,   Dramane.
Despite the importance of rice in Ivorians's diet, and thus in the economy of the Ivory Coast, self-sufficiency in rice production, until recently, has received little attention from economists and statisticians.  Agronomists, sociologists and anthropologists have examined in some detail the cultural practices, soils, land barriers, tools and basic techniques used by the Ivorian farmers.  But they have failed to produce much needed basic information related to crop acreage, yields, prices and other areas which are most relevant for policy formulation.  This paper analyzes the rice demand and supply in the Ivory Coast, and attempts to estimate both price and income elasticities of demand, and price elasticity of supply.

An Analysis of Scope Economies and Specialisation Efficiencies Among Thai Shrimp and Rice Smallholders
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mekhora,   Thamrong; Fleming,   Euan M.
Smallholders increasingly combine shrimp culture with the more traditional rice enterprise in regions of Thailand suitable for raising shrimps. They can exploit cost complementarities in production by combining activities in these enterprises within their farming systems. At the same time, it makes them more susceptible to on-farm negative externalities between rice and shrimp production, in both directions, causing scope diseconomies. A stochastic input distance model is estimated using data on shrimp and rice production by 52 smallholder households. Results from the estimated model are used to establish whether scope economies or diseconomies exist and whether specialisation in either shrimp or rice production significantly influences technical...

AN ANALYSIS OF THE COMPARATIVE ADVANTAGE AND POLICY INCENTIVES OF COMMERCIAL WHEAT PRODUCTION IN SOUTH AFRICA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kirsten,   Johann F.; Ohene-Anyang,   E.; van Rooyen,   Johan.
Despite the fact that all direct and indirect measures of subsidisation and protection have been removed, commercial agriculture is still widely considered to be subsidised, privileged and uncompetitive. This paper shows how the process of deregulation has in fact changed the situation. The paper reports on the comparative advantage in the production of wheat in South Africa and reveals the various distortionary effects, if any, of the policy environment on the production of wheat in the country prior to 1997. The paper concludes that South Africa has a strong comparative advantage in the production of wheat, especially, in the inland areas. Favourable climatic and soil factors as well as abundant and relatively cheaper domestic factors of production may...

AN ANALYSIS OF THE COMPETITIVENESS OF SOUTHEASTERN FRESH VEGETABLE CROPS USING QUADRATIC PROGRAMMING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chien,   Ming-Che; Epperson,   James E.
This study determined the competitive potential of the temperate southeastern U.S. region to produce selected fresh vegetables for the national market. Results indicated that the region may be competitive in the production and marketing of snap beans, cucumbers, bell peppers, and spring tomatoes. The region would also be competitive in the production and marketing of broccoli, summer and fall tomatoes, and spinach, given cost reductions of 10 to 15 percent. Major cost reductions were required for the region to be competitive in the production and interregional marketing of sweet onions in the absence of effective product differentiation.

AN ANALYSIS OF THE IMPACT OF A BAN OF METHYL BROMIDE ON THE U.S. WINTER FRESH VEGETABLE MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Deepak,   M.S.; Spreen,   Thomas H.; VanSickle,   John J.
This study evaluates the economic impact of a ban on methyl bromide on the U.S. winter fresh vegetable market for six major crops: tomatoes, green peppers, cucumbers, squash, eggplant, and watermelons. Florida is the primary domestic supplier of these products. Mexico and Texas are the competing suppliers of the five vegetable crops and peppers, respectively. Leontief technologies represent both monocrop and double-crop production systems; linear inverse demand functions represent four demand regions in the U.S. and Canada. By increasing production costs and reducing yields, a ban on methyl bromide decreases Florida's FOB revenues by 54% and increases those of Mexico by 65%. Price increases to U.S. fresh vegetable consumers range from near zero to over...

AN ANALYSIS OF THE IMPACTS RESULTING FROM THE 2002 FARM BILL ON INDIANA FRUIT AND VEGETABLE GROWERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Althoff,   Kyle; Gray,   Allan W.
The 2002 Farm Bill has negatively impacted the finances of new/expanding fruit and vegetable (FAV) growers interested in diversifying their operations. Producers wishing to grow FAV on farms that do not have a historical record of such production must either remove their farm from government program payments or face penalties for planting FAV on subsidized acres.  If a grower removes a farm from the program, he/she will lose the government payments for the entire farm, not just the acres that are planted to FAV production. Combined with penalties for producing on any land without historical production in FAV, the addition of soybeans as a base eligible crop has unintentionally removed thousands of Midwestern acres previously available for FAV production....

AN ANALYSIS OF THE LOAN DELINQUENCY OF MICHIGAN CASH GRAIN FARM BORROWERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Grabemeyer,   June C.
The 1970's were characterized by growth in agriculture.  There were increases in agricultural exports and prices received by farmers.  Cash and feed grain production expanded in response to these price signals.  Gross farm income rose from $58.8 billion in 1970 to $167.9 billion in 1981.  In Michigan, the value of farmland and buildings grew from $326 per acre in 1970 to a peak of $1,289 per acre in 1981.  Increasing asset values enabled farmers to use unrealized capital gains on assets as collateral for loans.  Farm real estate debt in Michigan increased from $667 million in 1970 to $2,058 million in 1981.  Total U.S. farm debt increased from $48,928 million in 1970 to $170,030 million in 1981.  The rationale for the increased use of debt financing in the...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chavas,   Jean-Paul; Pope,   Rulon D.; Kao,   Robert S.
An integrated investigation of futures price, cash price, and government programs is presented in the context of an econometric model of acreage supply response for U.S. corn and soybeans.  The analysis refines the role of different sources of price information in the farmers' acreage decision.  It is found that the government corn support price program plays a major role in corn and soybean production decisions.  Also, the results indicate that futures prices are not good proxies for expected future cash prices in the presence of government programs.  This raises questions about the information efficiency of futures prices when government intervenes in the market place.

An Analysis of the Role of Tile-Drained Farmland Under Alternative Nitrogen Abatement Policies
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Petrolia,   Daniel R.; Gowda,   Prasanna H.
Agricultural nitrogen is a major contributor to Gulf of Mexico hypoxia, and research has shown that agricultural subsurface tile drainage is a major carrier of nitrogen from croplands to streams and rivers. This study compares the results of abating nitrogen under a retired-land minimization policy with those of a new revenue-maximizing policy, paying particular attention to the role of tile-drained land. Findings reveal the retirement-minimizing policy resulted in more tile-drained land being retired and less being fertilizer-managed than was optimal under the net-return maximizing policy. Also, it led to a greater economic burden being shouldered by tile-drained land. Under both cases, tile drainage dominated the abatement process.

In this paper we analyse the technical efficiency of cotton farmers in the Punjab Province in Pakistan. Technical efficiency is measured relative to a stochastic frontier production function (SFPF). The estimated model includes a function in which technical efficiency is made an explicit function of firm specific factors (involving the levels of education and experience of farmers and other factors). For the purpose of analysis, survey data was collected for the 1996-97 season. Analysis is done on a district basis and the mean technical efficiencies obtained are 76, 78, 77 and 83 per cent for the districts of Arifwala, Bahawalpur, Multan and Rahim Yar Khan respectively. This study suggests that there is considerable room for productivity gains for the...

Specialty crops have been cited as means to diversify crop portfolios on the prairies.  Lentils, a specialty crop, have high variability in yields and prices but are relatively uncorrelated with the yields and prices of other traditional Saskatchewan crops.  In addition, yields and prices of lentils may be negatively correlated.  These attributes have important but offsetting effects in crop portfolio selection.  The objective of this article is to assess the relative profitability and riskiness of wheat and lentil rotations for a representative Saskatchewan farm and to select appropriate farmers who should consider production of lentils.  The cumulative density function of net returns are simulated for both rotations assuming stochastic prices and yields....

Marketing direct to consumers takes special skills and abilities on the part of marketers, and also requires a favorable location with respect to land resources and local markets. Since many farmers and direct market managers lack the resources and experience to compete with supermarkets, it is important for direct marketing operators to differentiate themselves from the mass marketers. The goal of this study was to analyze the effectiveness of direct marketing activities and marketing strategies used by New York vegetable farms. A survey designed to collect information on farm retail marketing practices from New York vegetable farms...

An Application of Mixed Logit Estimation in the Analysis of Producers’ Stated Preferences
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kipperberg,   Gorm; Bond,   Craig A.; Hoag,   Dana L.
This paper analyzes Colorado Corn producers’ preferences over both private- and environmental public-good production system attributes. Current production practices are characterized by intensive water and chemical use, resulting in non-point source pollution to water bodies as well as soil erosion problems. Data from a stated preference survey are employed to analyze key attributes of experimentally configured irrigation systems, proposed as alternatives to current practices. Panel mixed logit estimations find positive preferences for profit, risk reduction, and, importantly, systems with less environmental impact in terms of nitrate leaching and soil erosion. The results also find presence of significant preference heterogeneity and a complementary...

An Assessment of Future Markets for Crops Grown Along the Columbia River: Economic Implications of Increases in Production Resulting from New Agricultural Water Rights Under the Columbia River Initiative
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Capps,   Oral, Jr.; Williams,   Gary W.
This report examines the likely effects of additional agricultural water rights under the Columbia River Initiative (CRI) on net crop revenues (hay, orchards, vegetables, potatoes, wheat, and other crops) in the state of Washington over the next 20 years. This study corrects for four potentially serious methodological flaws made in two previous studies associated with the CRI and concludes that those studies substantially overestimated the net revenues accruing to producers in the Columbia River area from new irrigated acreage under the CRI. In fact, the net revenues are more likely to be negative than positive. Methodological errors made in the two previous studies lead to results that support a policy prescription that is just the opposite of what would...

Autores: Singh,   Rajinder Pal; Brennan,   John P.; Lacy,   John; Steel,   Felicity.
Ricecheck, a best management practices extension program for rice production in Australia, was developed by the NSW Department of Primary Industries advisory staff, Finley, in 1986. The program is based on eight best management practice recommendations called ‘Key Checks’ that are considered essential for achieving high yields. Economic analysis of the program reveals that there are significant financial, social and environment benefits from the adoption of the program. The results further reveal that the funds invested since 1986 by both NSW Department of Primary Industries and the Rural Industries Research and Development Corporation have been sound investments.

AN AUTOMATED ECONOMETRIC APPROACH FOR ESTIMATING AND REPORTING DAILY COTTON MARKET PRICES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brown,   Jeff E.; Ethridge,   Don E.; Hudson,   Darren; Engels,   Carlos.
An automated price reporting system developed through computer technology and hedonic price theory is used to estimate daily cotton market prices, premiums, and discounts. This objective approach for reporting cotton market prices was developed to complement the objective measures of high volume instrument grading of cotton. The computerized, econometric system is limited to the Texas and Oklahoma marketing regions where sales are readily available from electronic markets. The econometric based system has shown all the characteristics of an efficient price reporting system; it is accurate, reliable, consistent, and repeatable in its working process and price estimates.

An econometric analysis of the competitive position of Australian cotton in the Japanese market
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chang,   Hui-Shung (Christie).
Although a relatively small producer, Australia exports but about 90% of its cotton production, making it the third largest cotton exporter. This means that export performance plays a major role in determining the profitability of the Australian cotton industry. The primary aim was to determine the competitive position of Australian cotton in the Japanese market, based on the AIDS model using data from 1972 to 1998. The main findings were that the United States had a relatively strong market position and that to improve its market position, Australia should become more cost competitive and/or improve its quality image through promotion.

AN ECONOMETRIC ANALYSIS OF THE SUPPLY OF MAIZE IN LESOTHO
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Phoofolo,   Marabe.
Lesotho is largely agrarian.  More than 90 percent of the Basotho population lives in rural areas.  Agriculture provides an important source of income for over 50 percent of the rural population and is the largest contributor to GDP.  Apart from migrant labour in the Republic of South Africa (RSA) and limited work in administration and commerce in the few urban centers, there are few employment opportunities other then agriculture. Under production of maize coupled with a growing population has lead to great shortages of maize in Lesotho.  The hunger and nutritional problems associated with the maize shortage problem prompted the Government of Lesotho to set out self-sufficiency goals, which if met would help solve the maize shortage problem.   In view of...

AN ECONOMETRIC EVALUATION OF STABILIZATION POLICIES FOR THE U.S. GRAIN MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Arzac,   Enrique R.
This paper evaluates stabilization policies by applying methods of stochastic control and dynamic analysis to an econometric model of the U.S. grain market. Its main results are: (1) the aggregate consumer and producer surplus generated by the model is insensitive to the choice of the market regime; (2) policies directed to stabilize prices at levels compatible with nondecreasing farm revenue require the management of both grain inventories and domestic supply; (3) price fluctuations are significantly less under optimal stabilization than in the unregulated version of the model; and (4) historical policies have destabilizing effects on the market model.

AN ECONOMIC ANALYSIS OF A CORN-SOYBEAN CROP ROTATION UNDER VARIOUS INPUT COMBINATIONS IN SOUTH CENTRAL TEXAS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Funk,   Robert D.; Mjelde,   James W.; Hons,   Frank M.; Saladino,   Vince A.
Eight input combinations of commercial fertilizer, insecticides, and herbicides on a corn-soybean crop rotation in the Brazos River Bottom of Texas are evaluated.  Input combinations which do not fully utilize all three inputs are consistently ranked higher by all criteria as the preferred input strategy for the corn-soybean rotation system.  These results, which indicate limited input crop rotations that fall somewhere between the extremes of conventional agricultural production and organic agriculture, deserve further attention as a possible production alternative.

This study examined the economic potential with and without carbon credit payments of two crop and tillage systems in South Central Kansas that could reduce carbon dioxide emissions and sequester carbon in the soil. Experiment station cropping practices, yield data, and soil carbon data for continuously cropped wheat and grain sorghum produced with conventional tillage and no-tillage from1986 to 1995 were used to determine soil carbon changes and to develop enterprise budgets to determine expected net returns for a typical dryland farm in South Central Kansas. No-till had lower net returns because of lower yields and higher overall costs. Both crops produced under no-till had higher annual soil C gains than under conventional tillage. Carbon credit...

An Economic Analysis of Control of the Western Corn Rootworm Variant across Indiana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: van Mellor,   Thuy; Alexander,   Corinne E.; Bledsoe,   Larry; Krupke,   Christian.
A variant of the western corn rootworm (CRW) has adapted to the widely used cultural practice of crop rotation. This study analyzed the economic value of control options controlling the western CRW variant across Indiana. The options analyzed are soil insecticides, seed-applied insecticides, the recently commercialized genetically modified corn to resist CRW (CRW corn), or not controlling the western CRW variant. The results suggest that the economic value of CRW corn may exceed that of the alternative options for corn producers with high western CRW variant pressure, irrespective of producers'’ risk aversion levels and have the highest economic value for risk-averse producers in the moderate western CRW variant pressure region of Indiana.

Autores: Chavas,   Jean-Paul; Kim,   Kwansoo; Lauer,   Joseph G.; Klemme,   Richard M.; Bland,   William L.
This study investigates the recent evolution of corn yield, with a special focus on the tradeoff between corn profitability and risk.  The analysis relies on time-series data from Wisconsin experimental farms at the edge of the Corn Belt.  An econometric model of corn yield, corn grain moisture, and corn profitability is specified.  Both conditional means and conditional variances are estimated for different sites in Wisconsin. The empirical analysis shows the changes in corn yield and profit over time and across space.  The evidence suggests that yield trends are due mostly to technical progress, with smaller effects generated by climate change.  On average, corn yield and profitability have improved faster in northern Wisconsin than in the Corn Belt....

Autores: Lacy,   R. Curt; Hill,   Gary M.
Comparisons of simulated NPV for Coastal and Tifton 85 bermuda-grass using experimental data, current input prices and historical hay and feeder cattle prices indicates that many producers would benefit by adopting this new cultivar. Cow-calf producers would benefit the most followed by stocker/replacement heifer producers and finally hay producers. When risk-aversion is introduced into the model, all cow-calf and stocker producers regardless of the level of risk-aversion should consider adopting T85. Moderately or extremely risk-averse hay producers would consider adopting T85, while those that are slightly risk-averse would be indifferent.

AN ECONOMIC ANALYSIS OF RESTRUCTURING THE SOUTH AFRICAN HAKE QUOTA MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)

Hake is the most valuable fisheries species in South Africa, with an estimated landed value of R658 million in 1997. The fishery is presently managed under an individual quota system, where total allowable catch (TAC) is set annually and divided up amongst quota holders according to past performance, without quota holders having to pay for it. Fundamental restructuring of the South African hake quota market is however due to take place in the near future as recommended by the White Paper on Marine Fisheries Policy (1997). Factor analysis of data collected from a postal survey of existing South African hake quota holders and rejected hake quota applicants suggests that distinct differences in attitudes towards restructuring exist amongst respondents.

This paper compares the economics of the abonera maize production system, in which maize is grown in rotation with a green manure crop (velvetbean, Mucuna deeringiana), with traditional bush-fallow cultivation of maize in the Atlantic Coast area of Honduras. A probabilistic cost-benefit analysis of introducing velvetbean into the existing maize cropping pattern is carried out for the field, farm, and regional level. The probabilistic approach allows for a more comprehensive assessment of economic profitability, one which recognizes that farmers are interested in reducing production risk as well as obtaining increases in average net benefits. The analysis reveals that the abonera system provides significant returns to land and family labor over the six-year...

Autores: Jacquet,   Florence; Butault,   Jean-Pierre; Guichard,   Laurence.
The paper aims to study the effects of reducing pesticide use by farmers in the arable sector in France and the feasibility of a policy target of reducing pesticide use by half. The originality of the approach is to combine statistical data and expert knowledge to describe low-input alternative techniques at the national level. These data are used in a mathematical programming model to simulate the effect on land use, production and farmers’ income of achieving different levels of pesticide reduction. The results show that reducing pesticide use by 30% could be possible without reducing farmers’ income. We also estimate the levels of tax on pesticides necessary to achieve different levels of reduction of pesticide use and the effect of an incentive...

An Economic and Institutional Analysis of Maize Research in Kenya
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Karanja,   Daniel David.
Maize, the most important food crop in Kenya, contributes 44 percent of the per-capita, calorie intake. Increases in maize production over the past three decades have been attributed to the availability and adoption of modern maize techniques, especially fertilizer and hybrid seed. This paper estimates the rate of return to maize research to be 53 to 61 percent, and reveals that his impact was aided by complementary agricultural extension and seed multiplication and distribution programs. The paper describes the institutional framework that may have led to one of Kenya’s agricultural research success stories. It also poses challenges to the future of maize production in Kenya.

An economic assessment of Insecticide Resistance Management strategies in the Australian Cotton Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hoque,   Ziaul; Farquharson,   Robert J.; Dillon,   Martin; Kauter,   Greg.
Cotton production in Australia is a high-value industry with about 90% of fibre produced being exported to Asia, primarily to Indonesia. One aspect of modern cotton production is the heavy usage of insecticide sprays to combat Helicoverpa insects. The high cost of sprays and the public view of the industry regarding its perceived impact on the environment have led to the development of integrated pest management strategies. The measurement of insecticide resistance within insect populations has also prompted the development of insecticide resistance management (IRM) strategies. The aim of the work reported here is to improve the understanding and adoption of IRM strategies by cotton growers. This is pursued by conducting an economic assessment of...

Autores: Berends,   Patrick T.; Diebel,   Penelope L.; Williams,   Jeffery R.; Schlegel,   Alan J.
The economic feasibility of fertilizing irrigated grain sorghum with compos ted manure is evaluated using net return budgeting and production function analysis. Although the use of compost is technically feasible, the economic analysis indicates that compost does not comprise a large percentage of the nitrogen source in the profit-maximizing combination with commercial fertilizer.

An Economic Evaluation of Beneficial Management Practices for Crop Nutrients in Canadian Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sparling,   Beth; Brethour,   Cher.
Environmental risk management is the process of measuring and/or assessing environmental risk and developing strategies to manage it. One strategy used in Canadian agriculture to manage environmental risk is the implementation of beneficial management practices (BMPs).     This paper provides a summary of a larger research project which explored farm profitability before and after participation in beneficial management practices, specifically those related to crop nutrients.  Based on producer perceptions and the assumptions used in this analysis, the results of this study indicate that the majority of the selected BMPs, including soil testing, minimum tillage, no-till and nutrient management planning, improved profitability for the representative farms....

Autores: Gondalia,   V.K.; Patel,   G.N.
The economic viability of aonla plantation in Gujarat has been studied through a sample of 120 aonla growers spread over 12 selected villages of the Kheda and Anand districts for the agricultural year 2003-04. It has been found that establishment of aonla orchard involves high investment, but the annual net returns are also quite high, after the third year of plantation. The values of economic parameters, viz. NPV, BCR, IRR and PBP have been found to be Rs 652652, 5.25, 65.03 per cent and 55 months, respectively at 10 per cent discount rate. Under varying cost and return situations, values of all these feasibility parameters have satisfied the acceptance rules for the investment proposition.

AN ECONOMIC EVALUATION OF SOYBEAN STINK BUG CONTROL ALTERNATIVES FOR THE SOUTHEASTERN UNITED STATES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chyen,   David; Wetzstein,   Michael E.; McPherson,   Robert M.; Givan,   William D.
Methyl parathion or Penncap M (an encapsulated methyl parathion) are used extensively throughout the United States for controlling stink bug pests in soybeans, Glycine Max (L.) Merrill.  However, this insecticide is highly toxic to mammals, birds, and non-target arthropods, and thus is less environmentally sound than other insecticides.  For environmental and human health considerations, investigating alternative insecticides for control is desired.  For this investigation, research based on field experimental data from Florida, Georgia, and Louisiana during the 1988 and 1989 growing seasons were employed.  Results indicate that alternative, currently available, and less toxic insecticides may reduce producer costs, increase yield, and improve soybean...

An Economic Evaluation of Soybean-Based Biodiesel Production on Commercial Farms in the Soybean-Producing Regions of KwaZulu-Natal: Some Preliminary Results
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sparks,   G.D.; Ortmann,   Gerald F.; Lagrange,   L.
Global biofuel production has risen substantially in recent years, driven primarily by government support for biofuel industries. The stated motivations for these initiatives are numerous and have varied over time. Soybeans are the only field crop produced in sufficient quantities in KwaZulu-Natal (KZN) that the South African (SA) industrial biofuel strategy identifies as a potential biodiesel feedstock. Preliminary results from a mixed integer linear programming model support the notion of Funke et al. (2009), who contend that the incentives and commitments outlined by the industrial biofuel strategy are inadequate to both establish and sustain a domestic biodiesel industry.

An Economic Evaluation of the Hass Avocado Promotion Order’s First Five Years
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carman,   Hoy F.; Li,   Lan; Sexton,   Richard J.
The U.S. avocado industry has evolved from an emphasis on seasonal domestic production of a mix of avocado varieties to year-round availability of domestic and imported Hass avocados. California avocado producers, who account for approximately 90% of U.S. avocado production and essentially all U.S. Hass avocado production, have funded promotional programs for avocados since 1961. With few imports of avocados prior to the early 1990s, the benefits from these demand-enhancing programs flowed directly to California producers.   Imports of avocados into the United States have increased steadily since then, resulting in a free-rider problem that led ultimately to creation of the Hass Avocado Promotion, Research, and Information Act of 2000. This act established...

An economic evaluation of the osmoregulation gene technology to the Australian wheat industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Farquharson,   Robert J.; Morgan,   J.M.; Brennan,   John P.
Episodes of rainfall irregularity and soil moisture deficit have focused attention on the widespread limitation of water supply on winter cereal crop production in Australia. This has motivated a number of efforts at breeding for improved drought tolerance. A recent example involves a cellular adaptation which mitigates water loss through solute accumulation (osmoregulation or osmotic adjustment). An assessment of the performance of osmoregulation yield response in the presence of climate change found that wheat cultivars with this gene are unlikely to be adversely affected by hotter and drier conditions across the wheat belt. The results of an economic evaluation of potential future innovations (wheat cultivars) from the osmoregulation gene technology are...

An Economic Framework for Evaluating New Wheat Varieties
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brennan,   John P.; Godyn,   Dirk L.; Johnston,   Brian G.
Estimation of the benefits of research using changes in producer and consumer surplus following a research-induced shift in the supply curve provides a useful framework for the analysis of new wheat varieties. However, the framework assumes an homogeneous product, which is not the case for wheat where there are changes in quality as a result of research. This aspect is particularly important where there is a trade-off between quality and yield, as in the case of a higher-yielding, but lower-quality wheat variety. The aim of this paper is to incorporate these quality aspects into an analysis based on a partial equilibrium framework by separating the wheat market into segments based on wheat quality. A change in the type of wheat produced can then be...

An economic production function was derived in an analysis of water application to corn by phonological time periods. The quantities of use of water by growth periods as delineated by physical stages were tested for influence on final output of dry matter and grain. Several years’ data for three locations were utilized. The results tend to confirm the conceptual models and previous work in this type of analysis. Certain periods of growth were more critical than others.

An Economic Risk Analysis of Tillage and Cropping Systems on the Arkansas Grand Prairie
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hignight,   Jeffrey A.; Watkins,   K. Bradley; Anders,   Merle M.
No-till (NT) has been shown to reduce fuel, labor, and machinery costs compared to conventional-till (CT) but very few rice producers in Arkansas practice NT.  The low adoption rate is most likely due to difficulties in management but also limited information on the profitability and risk of NT.  Most rice producers are knowledgeable on NT costs savings but consider it less profitable due to yield reductions offsetting costs savings.  This study evaluates production costs, crop yields, and economic risk of both NT and CT in five rice-based cropping systems (continuous rice, rice-soybean, rice-corn, rice-wheat, and rice-wheat-soybean-wheat).  Yields, crop prices, and key input prices are simulated to create net return distributions.  Stochastic efficiency...

Specialty crop producers’ marketing problem, associated with lack of quality standards and advertising revenues, may detract from profitability. Although marketing orders, approved by producer referenda, offer a means to address these problems, institutional rules can make ratification difficult. In this study, economic structure was found to be more important than producer characteristics in explaining voter behavior in a Georgia Vidalia onions marketing order referendum.

Autores: Srinivasan,   Chittur S.; Shankar,   Bhavani; Holloway,   Garth J.
Under the TRIPs Agreement, all member-countries of the World Trade Organization are required to provide an "effective" system of plant variety protection within a specific time frame. In many developing countries this has led to a divisive debate about the fundamental desirability of extending intellectual property rights to agriculture. But empirical studies on the economic impacts of PVP, especially its ability to generate large private sector investments in plant breeding and facilitate the transfer of technology, have been very limited. This paper examines two aspects of the international experience of PVP legislation thus far (i) The relationship between legislation, R&amp;D expenditures and PVP grants, i.e., the innovation effect, and (ii) The role...

AN EMPIRICAL BARGAINING MODEL OF PRICE DISCOVERY: AN APPLICATION TO THE WASHINGTON/OREGON ASPARAGUS INDUSTRY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Folwell,   Raymond J.; Mittelhammer,   Ronald C.; Wang,   Q.
The bargaining process and its role in price discovery within the Pacific Northwest asparagus industry is analyzed using a general empirical bargaining model.  Growers' and processors' inverse supply and demand functions define boundaries for the negotiated prices.  OLS and Heckman's two-stage estimation procedures are used to estimate a stochastic bargaining model of price determination.  The results indicate that basic supply and demand forces exert substantial influences on the bargaining process.  In particular, expected levels of supply play a paramount role in the level of prices offered, while past prices also influence current offers.  The general framework of analysis used in relation to asparagus can be generalized to other commodities where...

AN EMPIRICAL EVALUATION OF YIELD PERFORMANCE AND CROSS-CROP YIELD CORRELATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Goodwin,   Barry K.; Mishra,   Ashok K.
This analysis considers two aspects of yield performance using a large sample of data collected from individual U.S. farms. In the first, observable farm and operator characteristics are related to relative yield perofmance. In general, larger, more diversified farms have higher relative yields. In addition, more intensive use of productive inputs tends to be associated with higher yields. In a second segment of the analysis, we focus on the extent to which yield performance for different crops on a single farm tend to be correlated. Our results suggest that farms in major growing regions tend to have greater correlation of crop yields. In addition, larger, more specialized farms tended to have more consistent yield performance across crops. Implications...

An empirical examination of import demand for pulses in India
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Agbola,   Frank W.; Damoense,   Maylene Y.
India is the largest producer and importer of pulses in the world. Since 1970, the Indian food economy has undergone major policy reforms, including trade liberalisation, that had the effect of opening up its domestic pulse market to international trade. This market is very lucrative and of major significance to the world pulse economy. Therefore, given the increasing evidence linking import demand and economic variables, an understanding of the impact of these variables on import demand for pulses in India is warranted. The import demand functions for total pulses, chickpea and lentils were estimated by autocorrelation regression procedure using time-series data for the period 1970 through to 2000. Empirical results indicate that real GDP, population,...

A simple model of the cereal harvest operation was constructed for the Wimmera region of Victoria. The model was used to investigate factors influential in determining the harvesting costs of a machinery system over a period of years. An evaluation of alternative machinery systems was also conducted using the model. The superiority of systems simulation over static analysis was demonstrated by using the model to incorporate stochastic variables and to handle the dynamic nature of the harvest operation. In addition, the model output was shown to provide more information for decision makers than had resulted from previous Australian studies. It was concluded that systems simulation is an appropriate technique for investigating farm management machinery...

An Empirically-Grounded Comparison of the Johnson System versus the Beta as Crop Yield Distribution Models
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ramirez,   Octavio A.; McDonald,   Tanya U.
Previous research established that the expanded Johnson system can accommodate any theoretically possible mean-variance-skewness-kurtosis combination. Therefore, it has been hypothesized that this system can provide for a reasonably accurate modeling approximation of any probability distribution that might be encountered in practice. In order to test that hypothesis, this manuscript develops a more flexible expanded form of the Beta distribution which, in its original form, has been widely used to model and simulate crop yields for risk analysis. Empirically grounded evaluations suggest that the Johnson system can model a variety of typical yield data-generating processes that are based on the Beta distribution much more precisely than the Beta can model...

Antibiotics are used in fruit production to control fire blight, a bacterial disease of fruit trees that causes yield losses and eventually tree death.  Fearing the development of widespread antibiotic resistance, scientists and public health officials are becoming increasingly concerned about antibiotics use in agriculture.  A framework is developed for assessing the impacts of changes in tree damage risk following a ban on antibiotics use in the apple industry.  Allowing for entry and exit, a long-run analysis of replanting dates and equilibrium prices is provided, as well as an estimate of the welfare impacts of a ban on antibiotics.

Using 1971-2000 data, we examine the accuracy of corn and soybean production forecasts provided by the USDA and two private services. All agencies improved their forecasts as the harvest progressed, and forecast errors across the agencies were highly correlated. Relative accuracy varied by crop and month. In corn, USDA 's forecasts ranked as most accurate in all periods except in August during recent times, and improved more markedly as harvest progressed. In soybeans, forecast errors were very similar with the private agencies ranking as most accurate in August and September and making largest relative improvements in August during recent times. The USDA provided the most accurate October and November forecasts.

AN EVALUATION OF EXPECTED VALUE AND EXPECTED VALUE-VARIANCE CRITERIA IN ACHIEVING RISK EFFICIENCY IN CROP SELECTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Reid,   Donald W.; Tew,   Bernard V.
This article evaluates the performance of expected value and expected value-variance criteria in achieving risk efficiency in crop selection.  Results indicate that the expected returns criterion achieves risk efficiency in many situations because of constraints.  However, in the absence of many constraints the expected returns criterion performs poorly except when highly mean-dominant activities are present.  The expected value-variance criterion achieves a high degree of risk efficiency for all situations examined.  This result implies that criteria more complex than expected value-variance are not necessary for crop selection analysis, given empirical returns distributions.

Agriculture development efforts in the past have focused heavily on increasing aggregate output in less developed countries (LDC).  In the last 2-3 decades, technology served as a key policy instrument used by developed countries to aid the less developed ones.  However, such a policy had led to the neglect of certain farming groups, particularly small farmers.  Recent trends in agriculture development tend to pay special attention to the needs of small farmers.  It is the small farmers who form the backbone of agriculture in many LDC's.  As their development receives priority, so does the need to gain a better understanding of their farming needs.  Small farmer response to technology has been unevenly distributed.

This research examines the predictability of a profit maximization model, an expected value-variance utility maximization (E-V) model, and two versions of the target-MOTAD model for modeling risky agricultural production decisions. Model solutions were translated into expected value and variance of farm income for analysis. Direct comparison and chi-square analysis of actual and predicted expected income distributions were used in the analyses. It was concluded that the utility maximization and cash-cost target-MOTAD models predicted distributions of farm income better than the variable-cost target-MOTAD and profit maximization models.

Autores: Brennan,   Lisa E.; Wegener,   Malcolm K.
Australian sugar-producing regions have differed in terms of the extent and rate of incorporation of new technology into harvesting systems. The Mackay sugar industry has lagged behind most other sugar-producing regions in this regard. The reasons for this are addressed by invoking an evolutionary economics perspective. The development of harvesting systems, and the role of technology in shaping them, is mapped and interpreted using the concept of path dependency. Key events in the evolution of harvesting systems are identified, which show how the past has shaped the regional development of harvesting systems. From an evolutionary economics perspective, the outcomes observed are the end result of a specific history.

An Ex Ante Analysis of the Benefits from the Adoption of Corn Rootworm Resistant, Transgenic Corn Technology
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Alston,   Julian M.; Hyde,   Jeffrey; Marra,   Michele C.; Mitchell,   Paul D.
This study examined the potential economic impacts in the United States of the commercial adoption of a corn rootworm (CRW) resistant transgenic corn. Using a counterfactual approach, we estimated that if the technology had been made available in the year 2000 at a price that would equate per acre costs to those for insecticide-based corn rootworm control, and adopted on all of the acres treated for corn rootworm in that year, the total benefits would have been $460 million. This benefit includes $171 million to the technology developer and seed companies, $231 million to farmers from yield gains, and a further $58 million to farmers from reduced risk, time savings, and other nonpecuniary benefits associated with reduced use of insecticides. This is a...

AN EX ANTE ASSESSMENT OF INVESTMENTS IN TEXAS GRAPEFRUIT UNDER UNCERTAINTY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Elmer,   Nicole A.; Thurow,   Amy Purvis; Johnson,   Jason L.; Rosson,   C. Parr, III.
The Dixit-Pindyck model was applied to examine the hypothesis that uncertainty associated with grapefruit production costs and returns is an important determinant of Texas grapefruit growers' investment behavior.  Freezes, price variability, and the effects of expanded trade were analyzed as risk factors.  An investment decision rule based on a net-present value calculation would approve a 25-year commitment to a 20-acre grapefruit grove, given a 6-percent discount rate.  The modified hurdle rate, calculated using an ex ante version of the Dixit-Pindyck model, is 24 percent.  The major source of the risk borne by Texas grapefruit investors is from freezes, rather than from expanded trade.

AN EXAMINATION OF ECONOMIC EFFICIENCY OF RUSSIAN CROP OUTPUT IN THE REFORM PERIOD
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Osborne,   Stefan; Trueblood,   Michael A.
This paper examines economic efficiency of Russian corporate farms for 1995-98.  Economic efficiency declined over the period, due to declines in both technical and allocative inefficiency.  According to the average technical efficiency scores, Russian agricultural production could improve from 17 to 43 percent according to DEA and SFA analysis, respectively.  The efficiency scores show that Russian agriculture presently uses relatively too much fertilizer and fuel and too little land and labor.   Russian agriculture inherited machinery-intensive technology from the Soviet era, which may be inappropriate given the relative abundance of labor in the post-reform environment.  Investment constraints have prevented the replacement of old machinery-intensive...

An Examination of Factors Influencing Fertilizer Price Adjustment
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Galbraith,   Craig.
This paper utilizes an error correction model to examine how anhydrous ammonia (AA) and urea prices at different locations in North America adjusted to changes in crop and input prices during two time periods: 2002 to 2005 and 2006 to 2009. The empirical results suggest that natural gas futures prices had relatively more of an impact on nitrogen fertilizer prices during the 2002-2005 period. Nitrogen prices tended to adjust more rapidly to increases in natural gas futures prices than decreases. In the 2006 to 2009 period, corn futures prices had more of an impact on nitrogen prices. Nitrogen prices tended to respond immediately to decreases in corn futures prices. The nitrogen price responses to increasing corn futures prices were mixed.

An examination of issues in the fisheries sector in a small island economy: The case of Tonga
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rohorua,   Halahingano.
Tonga as a small island economy faces continuos trade deficits. The Government has identified the fisheries sector as having great potential. This paper explores current issues in the fisheries sector in Tonga. The emphasis in this paper will be on issues in fish exports from Tonga. It is perceived that barriers to trade have been a major contributing factor to the sector’s poor performance. The focus here is on the financial returns that fishermen receive and the influences that the sizes of operators and types of fish exported have on the return to the exporters/fishermen in Tonga.

AN EXAMINATION OF PROFIT INEFFICIENCY OF RICE FARMERS IN NORTHERN GHANA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Abdulai,   Awudu; Huffman,   Wallace E.
This paper employs a stochastic frontier model to examine profit inefficiency of rice farmers in the Northern Region of Ghana using farm-level survey data. The efficiency index, based on a half-normal distribution of the stochastic error term is related to farm and household characteristics. The empirical results show that farmers' human capital represented by the level of schooling contributes positively to production efficiency, suggesting that investment in farmers' education improves their allocative performance. Access to credit and greater specialization in rice production, are found to be positively related to production efficiency. A farmer's participation in nonfarm employment and being older, however, reduce production efficiency.  Farmers...

An Examination of the Relationship Between Subsidies on Production and Technical Efficiency in Agriculture: The Case of Cotton Producers in Greece
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Emvalomatis,   Grigorios; Oude Lansink,   Alfons G.J.M.; Stefanou,   Spiro E.
Subsidies on production have long been criticized for protecting producers from competition, and thus removing an incentive for efficient use of the resources. This study undertakes the examination of the impact of partially decoupled subsidies on the technical efficiency scores of cotton producers in Greece. The results indicate that compensatory area payments reduce the efficiency scores of the producers by diverting resources from products for which the subsidy is based on the area planted to the production of cotton, for which the aid is related to the volume of output.

CORPOICA and IFPRI implemented a research project in Ventaquemada, Colombia. The project’s goal was to asses the benefits of Integrated Pest Management (IPM) practices and the potential of Genetically Modified insect resistant (Bt) potatoes to manage damage caused by the Guatemalan Tuber Moth (Tecia solanivora Povolny). The Guatemalan Tuber Moth is particularly destructive because field spraying on the adult stage is ineffective and there exists damage specificity to the tubers. Excessive pesticide sprays have resulted in resistance to several insecticides. Insect resistant (Bt) potatoes has been shown an effective means to control other members of the Tuber Moth complex. Thus a Bt potato may play a role in managing Tecia in Colombia. This is an ex ante...

Autores: Franco-Dixon,   Mary Ann.
The $2.1 million invested for the sweet corn research breeding program resulted in the release of Hybrix5 in 1995 which is a new sweet corn variety with improved insect and disease resistance. Based on the ex-post evaluation of this research program, it was estimated that the net benefits of the program up to 2006 (in 2006 dollars) is around $3 million. The producer benefits are 4.5 times the costs of R&amp;D. Extending the period up to 2012 (20 years) resulted in estimated net benefits of around $6 million in 2006 dollars. The producer benefits are 7.2 times the costs of the R&amp;D.

This book contains a sampling of recent ERS research illustrating the breadth of the Agency’s research on current policy issues: from biofuels to food consumption to land conservation to patterns of trade for agricultural products. What you won’t find in this collection is any mention of economists’ favorite analytic tools (regression analyses, for example, and coefficients of variation). We wanted this guide to highlight results, not process. Even so, the findings on display here are all based on rigorous and robust application of such tools as well as use of the latest econometric techniques.

An Innovative Approach for Modeling Crop Yield Response to Fertilizer Nutrients
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Upadhyay,   Bharat Mani; Smith,   Elwin G.; Favret,   M. Lucila.
Fertilizer recommendations seldom account for agro-climatic conditions, which are important factors that determine the response to fertilizer and the optimal rate of fertilizer. The nitrogen fertilizer response to open pollinated and hybrid canola types will also impact optimal nitrogen rates. This study used quantile regression to model canola yield response to nitrogen fertilizer. Quantile regression can apply different weights to the residuals, facilitating a response estimation where the agro-climatic conditions are not limiting and the yield response is due to the variable of interest. The economically optimal levels of fertilizers were calculated using the proposed and the conventional least squares procedures of the two canola types in western...

AN INTEGRATED ON-FARM EXPERIMENT AND SURVEY APPROACH TO MAIZE AND GROUNDNUT CONSTRAINT ANALYSIS IN ZIMBABWE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shumba,   Enos Mutambu.
On-farm trials conducted in Zimbabwe communal areas (peasant sector) have demonstrated the existence of a yield gap between potential farm yields and those achieved by farmers.  This study utilizes the experimental and survey approach to quantify the size of the maize and groundnut yield gaps at the farm level and evaluates the economic returns associated with the yield increasing technologies.  Three major conclusions drawn from the study are:  First, the diagnostic survey and the yield gap package approach substituted for each other in identifying technical constraints for designing on-farm trails.  Second, the magnitude of the yield gap alone could not be used to justify the initiation of a groundnut trial program versus maize, since costs of recovering...

Autores: Bernardo,   Daniel J.; Whittlesey,   Norman K.; Saxton,   Keith E.; Bassett,   Day L.
A two-stage simulation/mathematical programming model is presented for determining the optimal intraseasonal allocation of irrigation water under conditions of limited water supply. The model is applied to a series of water shortage scenarios under both surface and center pivot irrigation. Economically efficient irrigation management is shown to involve the coordination of a number of managerial decisions, including irrigation scheduling, crop substitution, the adoption of improved irrigation labor practices, and idling land. The results indicate that significant opportunities exist for conserving water in the study area under both surface and center pivot irrigation.

An Unbalanced Nested Error Component Model for Estimating  Pest Damage Functions and the Value of Rootworm Bt Corn
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dun,   Zhe; Mitchell,   Paul D.
We apply Antweiler’s (2001) double-nested unbalanced panel data model to estimate a western corn rootworm damage function using data from field trials in Illinois and Nebraska.  Results imply that expected yield losses for a one unit difference in the node injury scale are 16.4%.  Estimated random year and state effects are statistically significant, as is the estimated random experimental effect.  The experimental effect is relatively large indicating the tremendous variability in yield losses at the small scale for plots with the same node injury scale measure of root damage.  Using the estimated pest damage function to assess the value of Bt corn for farmers in Nebraska and Illinois, we find that, with a mean yield of 200 bu/ac, a yield CV of 25%, a...

This study aimed at the technical-economical evaluation of implanting some vegetal-oil extraction units in order to insert the family agriculture into bio-diesel production chain. Three project models (arrangements) for vegetal-oil extraction units at different sizes were proposed, using extraction by pressing and mixed extraction (extracting by either pressing or solvent) and different raw materials (castor-oil and soybean). For the size analysis, the oil production scales between 50/60 tons/day were used with real market data concerning investments, inputs prices of the process, raw materials and vegetal oil. For the economic analyses, the software BioSoft was used. The BioSoft is a program for supporting the decision-making process, which was developed...

Analysing Linkages between Strategy, Performance, Management Structure and Culture in the Spanish Fresh Produce Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Martinez,   Marian Garcia; Poole,   Nigel D.
This article reports the results of an industry-level study that seeks to identify empirical regularities between firm strategy, management style, organisational structure and performance in the Spanish fresh fruit and vegetable (fresh produce) industry using strategic group analysis. Groups were formed from key dimensions reflecting firms' strategic orientations. Performance levels did not differ systematically between strategic groups, but performance was found to be influenced by the alignment between entrepreneurial culture and organisational structure. A move towards greater flexibility and/or adopting an entrepreneurial style are both likely to contribute to an improvement in the overall performance of the firm.

Analysing Profits and Economic Behaviour of Organic and Conventional Dutch Arable Farms
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Oude Lansink,   Alfons G.J.M.; Jensma,   Klaske.
This paper uses a micro-econometric model to analyse differences in variable profits and economic behaviour between organic and conventional arable farms. Insight in factors underlying these differences is essential in designing policy measures that aim at encouraging the transition to a more sustainable farming practice. The framework is applied to a rotating panel of Dutch conventional and organic arable farms over the period 1990-1999. The results show that the, on average larger variable profit of organic farms is mainly associated with the use of land and technological changes. The shadow price of labour suggests over-use of labour on organic arable farms. Demand for pesticides and supply of output are generally more elastic on organic farms....

Potential adjustments in U.S. commodity program for rice are evaluated in this paper using stochastic analysis in a global modeling framework. Corresponding threshold and loss-compensatory increases in target price and loan rates are determined with assumed outright and gradual elimination of direct payments. Results show that if direct payments (DP) are eliminated in 2012, a 23% increase in both the target price (TP) and loan rate (LR) triggers counter-cyclical payments (CCP) 80% of the time; and it will take an increase of 48% in TP and LR to generate CCP enough to compensate for the loss in total DP. If DP is gradually removed over 5 years, the trigger and compensatory increases in TP and LR are 41% and 46%, respectively. Furthermore, if DP is...

ANALYSIS OF DRY BEAN PRICE BEHAVIOR IN BURUNDI
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ndarusigiye,   Mevin.
Dry bean production and price statistics for Burundi from 1972 to 1987 indicate significant year-to-year (bean production) and monthly (bean prices) fluctuations.  These fluctuations are influenced by, among other things, climatic conditions, unpredictable markets, government policy, and phytopathological factors.  The objective of the study is to analyze the behavior of dry bean production in Burundi under uncertain prices and assess the degree of uncertainty for the period 1972-1987.  The hypotheses are that dry bean prices in Burundi are uncertain, and that annual dry bean production per capita has been falling because of dry bean price uncertainty.  Two types of regressions models, one with average annual data and another with monthly real price data,...

New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development. However this is a challenging process since conventional environmental efficiency measures are usually based on simple input and output flows but nitrogen discharge is a...

In the United States, biomass is the largest source of renewable energy accounting for over 3 percent of the energy consumed domestically and is currently the only source for liquid, renewable, transportation fuels. Continued development of biomass as a renewable energy source is being driven in large part by the Energy Independence and Security Act of 2007, which mandates that by 2022 at least 36 billion gallons of fuel ethanol be produced, with at least 16 billion gallons being derived from cellulose, hemi-cellulose, or lignin. However, the market for cellulosic biofuels is still under development. As such, little is known about producer response to feedstock prices paid for dedicated energy crops. While there have been some studies done on factors that...

Analysis of Farm Household Preferences in the Management of Invasive Species: The Case of Miconia in Hawaii
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chan-Halbrendt,   Catherine; Yang,   Fang; Thomas,   Lynna; Pant,   Archana.
A major threat to Hawaii's ecosystem is the spread of invasive plant species. One such species is Miconia calvescens. Given that this plant was originally introduced to Hawaii by the horticulture industry and has negative effects on agricultural productivity, it is logical to find the farm households' preference for the control of Miconia. Using Conjoint Choice Experiment methodology, this study designed a survey to measure farm households' preferences for Miconia calvescens control program attributes. Results of the surveys indicate that the farm households are willing to support Miconia control programs if they prevent severe soil erosion and loss of biodiversity.

Autores: Weatherspoon,   Dave D.; Davis,   Christopher G.; Olorunnipa,   Zacch.
The Rotterdam model was used to determine the demand for fresh table grapes in Canada, Japan, and Sweden from 1971-1990.  Results of elastic expenditure elasticities and cross price elasticities indicating that U.S. grapes are considered substitutes for grapes from other countries, suggest that the U.S. grape producers have a competitive edge in these countries.  The trade agreements and trade negotiations with Canada and Japan will assist in making relative prices lower for U.S. grapes, encouraging their consumption.  Lastly, Canada, Japan, and Sweden are all expected to grow in wealth, as well as their demand for fruit, especially grapes.

Autores: Nhundu,   K.; Mushunje,   Abbyssinia.
Irrigation development is a gateway to increased agricultural, water and land productivity, increased household and national food security. However, irrigation development has been a major challenge in many developing countries, including Zimbabwe. The launch of the Fast Track Land Reform Programme (FTLRP) in 2003 ushered in new unskilled cadres and this was followed by a reduction in area developed for irrigation from 200,000ha to approximately 120,000ha. This was due to thefts, dilapidation, and vandalism of irrigation infrastructure. The government made efforts to develop and bring back the 200,000ha into operational, but little has been achieved. To assess irrigation development post FTLRP, a case study was done in Goromonzi District. Using a Trend...

Multifunctional agriculture is particularly fundamental to some working lands conservation policies and programs, such as the Environmental Quality Incentive Program (EQIP), Conservation Security Program (CSP) and Wildlife Habitat Incentive Program (WHIP). Farmers can also be engaged in providing recreational and agri-tourism services such as hunting, fishing, bird-watching, farm tours, petting zoos and hospitality services. Using the Agricultural Resource Management Survey (ARMS) we analyze factors associated with participation in conservation, recreation and agri-tourism activities as a function of farm structure, farm financial measures, production practices, and socio-demographic characteristics of the farm operator.

Results for 19 CIMMYT projects suggest among other things that participatory approaches at the center were largely “functional”—that is, aimed at improving the efficiency and relevance of research—and had in fact added value to the research efforts. The authors suggest that CIMMYT should (1) create a more conducive environment for scientists to share experiences on such approaches and (2) better document their impacts on farmers’...

Autores: Cardenas,   Gabriela; Vedenov,   Dmitry V.; Houston,   Jack E.
Despite the decline of coffee prices during the 1990s, coffee production remains a main economic activity for producers in Southeastern Mexico. This paper analyzes the coffee production system for 24 municipios, or districts, in Veracruz, Mexico during a five-year cropping period (1997-–2002). A stochastic frontier approach is used in order to estimate an input distance function and evaluate production efficiency during the period. Factors such as coffee quality and access to markets are tested in terms of their effect on efficiency. The results show the production process in these municipios, as measured by technical efficiency, seems to be stable over time despite of price fluctuations in the global market. Production of staple crops (corn) along with...

Analysis of profitability and risk in new agriculture in a Himalayan watershed by using dynamic non-linear programming model
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sharma,   Rakesh Kumar; Sankhayan,   Prem Lall; Singh,   Ranveer.
Cropping pattern in the Himalayan region of India has undergone a significant change in the recent past. Introduction of horticultural crops of vegetables, fruits and flowers have led to more intensive agriculture. Such a change, resulting in higher incomes and improvements of the overall living conditions has, however, been accompanied with increased income risk. This emphasises a need for proper analysis of the cropping pattern, at an appropriate scale, such as, a micro watershed. This was achieved by constructing a dynamic non-linear programming model incorporating appropriate objective function, constraints and crop and livestock activity budgets along with risk component present in the gross returns. The model was then solved under alternate policy...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Villano,   Renato A.; Fleming,   Euan M.
There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level.  In this study, we analyse technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure.

ANALYSIS OF THE DEMAND AND SUPPLY FUNCTION OF WHEAT IN SAUDI ARABIA PROJECTION OF SUPPLY AND CONSUMPTION THROUGH 1985
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Khalid,   Al-Hamoudi.
With the recent rapid increase in urbanization, wealth, and foreign technicians and labor in Saudi Arabia, wheat is becoming an important diet staple.  A sufficient wheat supply and stabilization of its price are vital to the society.  Yet because of industrial development and economic growth, the total area used for wheat production in Saudi Arabia dropped from 125,000 hectares in 1972 to 45,000 hectares in 1973.  Consequently, the Kingdom has become increasingly dependent on imported wheat.  The objectives of this study are to:  1)  select appropriate variables to establish an estimated supply equation; 2) select appropriate variables to establish an estimated demand equation and 3) apply these two estimated equations to make demand and supply projections.

Analysis of the Governance Structure used by Eksteenskull Raisin Producers: Is there a need for more Vertical Coordination?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jordaan,   Henry; Grove,   Bennie.
Eksteenskuil raisin producers are a group of emerging raisin producers who are successfully participating in a sophisticated value chain. They collectively export their raisins through the fairtrade initiative. Emerging farmers typically face high levels of transaction cost. The high levels of transaction cost in combination with the changing nature of the marketing environment, suggest that the different modes with which transactions can be coordinated need to be assessed in order to identify that mode that would minimise the transaction cost. The aim of this paper is to investigate the governance structures that are employed by Eksteenskuil raisin producers in order to determine whether an alternative may not contribute to reducing transaction costs...

Analysis of the Impact of CIMMYT Research on the Australian Wheat Industry

Autores: Brennan,   John P.; Quade,   Kathryn J.
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers have provided benefits to Australia averaging A$30 million per year since 1973. If these benefits are to continue in the future, Australia must continue its close relationship with CIMMYT.

Autores: Renwick,   Alan W.; Revoredo-Giha,   Cesar.
The purpose of the paper is examining the potential implications for the UK sugar beet sector of the EU sugar regime reform. Although the reform has yet to be formalised, the initial proposals centre on price and quota cuts. Using panel data from the Farm Business Survey for England, the paper estimates two cost functions: one for the sugar enterprise and another for the cropping part of the farm (i.e., excludes any livestock enterprise) and use them to analyse the impacts on profitability and costs of three possible reform scenarios: a 25 per cent cut in UK quota, a 25 per cent cut in price, a 40 per cent cut in price. The results show that the largest gains in terms of economic efficiency would be achieved under the 40 per cent price cut; however, the...

Analysis of the Soybean-to-Corn Price Ratio and its Impact on Farmers' Planting Decision-Making in Indiana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ubilava,   David.
In Indiana agricultural land is used mostly for corn and soybean harvesting. Rotated corn is a common practice, but in recent years, essentially due to the "ethanol boom" and increased profitability of corn production, many farmers have switched to continuous corn. Corn price increase affects the soybean-to-corn (STC) ratio, however, it is hypothesized that over time market effects will be felt, and return the ratio to its stable range. The threshold autoregressive model is used to analyze the monthly time series of STC ratio in Indiana. Results suggest that exogenous shocks will not have permanent effect on the STC price ratio, but will require, however, a reasonably long time to die out.

Beans are widely grown as a major food crop in Eastern and Southern Africa. It is the most important staple food crop after maize in Kenya (ECABREN, 2000). The beans industry in Kenya is faced with problems of shortages, seasonal supply and price fluctuations and inadequate information on production, marketing and consumption. These problems are more acute in urban areas. This paper analyzes the structure and performance of the beans marketing system in Nairobi metropolitan area, the single most important beans market in Kenya. Data from a sample of 102 traders augmented by secondary data were used to analyze the marketing system by applying descriptive statistics, concentration ratios and co-integration models. The results showed that the beans marketing...

Analysis of the technical efficiency of rice farms in Ijesha Land of Osun State, Nigeria
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tijani,   A.A.
This study estimated technical efficiencies on rice farms in Osun State, Nigeria, and identified some socioeconomic factors, which influence productive efficiency. These technical efficiencies were estimated using the stochastic frontier production function approach applied to primary data. A translog production function was used to represent the production frontier of the rice farms. The study showed that the levels of technical efficiency ranged from 29.4% to 98.2% with a mean of 86.6%, which suggests that average rice output falls 13.4% short of the maximum possible level. Therefore in the short run there is scope to increase technical efficiencies on rice farms in the study area. The study also showed that these efficiencies are positively and...

The world of oilseeds, meals, and oils has been evolving.  New issues have emerged for researchers and policymakers.  The United States is still the largest player, mainly due to its dominant position in soybeans and soybean meals.  Nevertheless, the position of the United States has been challenged by several countries.  The growth by Brazil and Argentina in the production of soybeans and soybean meal has especially eroded the market share of the United States in recent years.  Malaysia and Indonesia have been aggressively marketing their palm oil, intensifying the competition for U.S. soybean oil exports.  Other issues include changing trade policies and demand in major importing countries, trade liberalization, and genetically modified crops.

The effects of U.S. wheat prices, dollar values, and their volatilities on U.S. wheat market shares in 10 Asian countries are analyzed.  The variables are converted to a relative form comparing the U.S. against Australian and Canadian variables in order to incorporate the effects of competition among these countries.  The effects of the increased loan rates and target prices in the early 1980s and the U.S. export enhancement program (EEP) are also analyzed.  Estimation results show that higher U.S. wheat prices and U.S. dollar appreciation have detrimental effects, while increases in competitors? wheat prices and currency values have cross positive effects on U.S. market shares.  The importers are not sensitive to volatility in annual price and exchange...

Analyzing Effects of the U.S. Duties on Canadian Hard Red Spring Wheat
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Baek,   Jungho; Mattson,   Jeremy W.; Koo,   Won W.
Since the United States imposed antidumping and countervailing duties totaling 14.16 percent on imports of Canadian hard red spring (HRS) wheat, Canadian exports to the United States have nearly stopped. This study examines the impact of the decreased HRS wheat imports from Canada on U.S. wheat prices and producer income. To measure the impacts of the U.S. duties accurately, special attention is paid to issues related to substitutability between HRS and hard red winter (HRW) wheat and third-country effects. Results suggest that the substantial decline in Canadian HRS wheat exports to the United States has increased U.S. HRS and HRW wheat prices and thus farm income.

Autores: Perry,   Gregory M.; Rister,   M. Edward; Richardson,   James W.; Grant,   Warren R.
Whole farm simulation analysis and econometric techniques are employed in an analysis of crop rotations and tenure arrangement strategies. The FLIPSIM model is used to analyze a representative Texas Upper Gulf Coast rice and soybean farm. Probit analysis is then used to determine the impact of net cash farm income, land tenure, and crop rotation on probability of survival. Results suggest that, although the simulation model is useful in providing information on the effect at the farm level of following the different strategies, probit results provide greater understanding into the returns and risk inherent to each strategy.

Autores: Yu,   Tun-Hsiang (Edward); Larson,   James A.; Gao,   Yuan; English,   Burton C.
It is generally believed that preprocessing procedure can reduce the transportation and storage costs of biomass feedstock for biofuel production by condensing the feedstock’s size. However, the capital costs of preprocessing facilities could be significant in the feedstock logistics system. Applying a GIS and mixed-integer mathematical programming model, this study evaluates the economic values of a preprocessing technology, stretch‐wrap baling, in the biomass feedstock supply chain for a potential commercial-scale switchgrass biorefinery in East Tennessee. Preliminary results suggest that the stretch-wrap baling equipment outperforms the conventional hay harvest methods in terms of total delivered costs. Although the densification process involves...

Analyzing the Effects of Weather and Biotechnology Adoption on Corn Yields and Crop Insurance Performance in the U.S. Corn Belt
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vado,   Ligia; Goodwin,   Barry K.
Favorable weather and the adoption of Genetically Modified (GM) corn hybrids are often argued to be factors that explain recent corn yield increases and risk reduction in the U.S. Corn Belt. The focus of this analysis is to determine whether favorable weather is the main factor explaining increased and more stable yields or if biotechnology adoption is the more relevant driving force. The hypothesis that recent biotechnology advances have increased yields and reduced risks by making corn more resistant to pests, pesticides, and/or drought is tested. Fixed effects models of yields and crop insurance losses as functions of weather variables and genetically modified corn adoption rates are estimated taking into account the non-linear agronomic response of...

We analyse the impacts of the CAP reforms on technical efficiency of Greek olive farms. We use a production frontier function and a non-monotonic inefficiency effects model which incorporates the influences of exogenous variables on the mean and the variances of farm efficiency. We formulate policy variables (e.g. the direct subsidies) and farm characteristics as explanatory variables in the inefficiency effects model. We use the 1995-2004 FADN data to estimate the production frontier, to derive technical efficiency, and to determine the effects of the explanatory variables. The study shows that the 10-year average technical efficiency of olive farms is 69%. Direct transfers have a negative and monotonic effect on technical efficiency, while the degree of...

Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of mountain olive groves in Andalusia (Southern Spain) at risk of abandonment after the decoupling of the EU subsidies as a case study. The economic valuation technique used is the Choice Experiment. According to the results, there is a different contribution of each attribute to the improvement of the Society level of utility.

Anticipated Impacts of GMO Introduction on Production Pattern In Poland
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Maciejczak,   Mariusz; Was,   Adam.
The paper takes one significant element of the agriculture production – use of genetically modified organisms (GMO) – and considers it in relation to the production pattern in Polish farms. It asks if under the ceteris paribus conditions the use of GMO plants in Polish farms will have influence on the cropping structure. To answer this question only a scientific and theoretical assumption has been applied that GMO cultivation is permitted without restrictions in Poland. The approach combines both the very short experience of the new biotech based system of agricultural production and a modeling, which builds up and aggregates the impacts of individual farm responses under assumed situations.

Antidumping and Market Power in the Agriculture Sector, with a Special Case Study of the Fresh Tomato Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Baylis,   Katherine R.
In this article we highlight the anticompetitive nature of antidumping (AD) legislation. Antidumping legislation was set up to protect domestic firms from predatory pricing by foreign firms. We argue that protecting highly concentrated industries drastically reduces competition at home. In cases where the industry consists only of one or two firms, import restriction may breed monopolies at the expense of domestic consumers. This article looks at cases filed by the agriculture sector, and at the market concentration of industries in this sector, to illustrate the above possibility. We study the case of fresh tomatoes in detail to further demonstrate the anticompetitive nature of AD legislation. We show the effect of AD legislation on imports, as well as...

Autores: Costa Ferreira,   Pedro Guilherme; Almeida,   Eduardo Simões de; Da Silva Alvim,   Maria Isabel.
De modo geral, assume-se, com freqüência, que na agricultura operam-se retornos constantes de escala. É interessante verificar essa hipótese para o caso da fruticultura, um setor dinâmico, ou seja, com elasticidade-preço da demanda maior do que um. Para ver isso, adotou-se uma abordagem da lei de Verdoorn, estimando-a pelo método das regressões ponderadas geograficamente (RPG). Os resultados mostraram que o melhor modelo para a agricultura no período de 1990 a 2004 foi o modelo de defasagem espacial local. O termo da defasagem espacial no modelo fornece evidências em favor da hipótese da existência de um efeito de transbordamento da pesquisa agrícola no Brasil. Houve, ainda, evidências de ocorrência de retornos crescentes de escala para a fruticultura...

The copula approach provides a powerful and flexible method to model multivariate distributions and thus go beyond joint normality, regressibility, and mean-variance criterion. Accurate estimation of joint distributions may help to improve the results in the area of risk management and insurance obtained under more limiting assumptions.

Autores: Sedlak,   Otilija; Kocic Vugdelija,   Vesna.
The aim of this paper is to set-up the algorithm for determining the degree of workability of the soil, to help the owners of family farms to plan working hours of agricultural machines, i.e. with the machine park management. The plans, which would be made by use of these algorithms and based on the accurate information of the cultivation conditions, would result in the appropriate use of time and capacity of the agricultural machines. In some sectors, such as agriculture or certain industries, chance that certain event occurs plays a very important role. The influence of random events, however, can be significantly reduced if decision makers are counting on them, reveal their nature and gather as much information about them as possible. Justification of...

A vizsgálatokból megállapítható, hogy a precíziós gazdálkodás bevezetésére irányuló beruházások megtérülése és az üzemi méretek között szoros az összefüggés. A feltételezett öt- és hatéves megtérülés mellett a hozam- vagy az elvárt kamatszint-változást a nagyobb területű üzemek képesek ellensúlyozni.    --Return on investment in projects for implementing precision farming is closely related to farm size. In the event of the envisaged repayment over five or six years, farms with a larger area can balance changes in yield or interest rate.

Are Corn and Soybean Options Too Expensive?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Urcola,   Hernan A.; Irwin,   Scott H.
A growing body of recent evidence suggests that premiums for financial options might be too high. For agricultural options, market participants often make similar claims, however there is very limited scientific literature to prove or disprove such claims. This research investigates the efficiency of corn and soybean options markets by directly computing trading returns. Time effects on market efficiency are also investigated. When the sample period is considered as a whole, risk adjusted returns indicate that no profits can be made by taking either side of the corn or soybean options markets. However, when time effects are analyzed, corn calls appear to have provided excess returns during the 1998--2005 period. This result do not appear to be driven by...

Are Corn and Soybean Trend Yields Changing in Illinois?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sheppard,   Jessica.
Crop yields are influenced by a complex combination of factors, including weather, seed genetics, soil quality, and production management. Regardless, yields still tend to show a general trend over time, which is referred to as the “trend yield.” There has been much debate over whether improved technology has caused trend yields to change in recent years. Many experts believe recent corn yield increases were caused by advancements in biotechnology for seed genetics. It has been suggested that a lack of research on soybean genetics has led to a plateau in the soybean trend yield. It has been widely accepted that these new trends began in the mid-1990s and that they should be used for estimating future yields. However, weather should be taken into...

ARE CROP YIELDS NORMALLY DISTRIBUTED?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ramirez,   Octavio A.; Misra,   Sukant K.; Field,   James E.
This paper revisits the issue of crop yield distributions using improved model specifications, estimation and testing procedures that address the methodological concerns raised in recent literature that could have invalidated previous conclusions of yield non-normality. It shows beyond reasonable doubt that some crop yield distributions are non-normal, kurtotic and right or left skewed, depending on the circumstances. A procedure to jointly estimate non-normal farm- and aggregate-level yield distributions with similar means but different variances is illustrated, and the consequences of incorrectly assuming yield normality are explored.

Are EU spatial ex ante coexistence regulations proportional?

Autores: Demont,   Matty; Daems,   W.; Dillen,   Koen; Mathijs,   Erik; Sausse,   C.; Tollens,   Eric.
The EU is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all member states. While it stresses that any approach needs to be “proportionate to the aim of achieving coexistence”, very few studies have actually attempted to assess whether the proposed spatial ex ante coexistence regulations (SEACERs) satisfy this proportionality condition. In this article, we define proportionality as a functional relationship which is weakly increasing in the incentives for coexistence. We propose a spatial framework based on an existing landscape and introduce the new concept of shadow factor as a measure for the opportunity costs induced by SEACERs. This enables comparing the proportionality of (i) rigid...

Are Horticultural Exports a Replicable Success Story? Evidence from Kenya and Côte d'Ivoire
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Minot,   Nicholas; Ngigi,   Margaret.
Kenyan horticultural exports are often cited as a success story in African agriculture. Fruit and vegetable exports from Côte d’Ivoire have received less attention, but the export value is similar to that of Kenya. This paper focuses on three questions. First, do the horticultural sectors of Kenya and Côte d’Ivoire constitute valid success stories? Second, what factors have contributed to the success (or lack thereof)? And third, to what degree can the success be replicated in other African countries? The paper finds that Kenyan horticultural exports are indeed a success story: horticulture has become the third largest earner of foreign exchange, more than half the exports are produced by smallholders, and smallholders gain from producing for the export...

Are Organic Farmers Really Better Off Than Conventional Farmers?

Autores: Hiroki,   Uematsu; Mishra,   Ashok K.
We employed the propensity score matching and estimated the causal effect of being certified organic crop producers on farm household income and its various components in the United States. Contrary to the standard assumption in economic analysis, certified organic farmers do not earn significantly higher household income than conventional farmers. Certified organic crop producers earn higher revenue but they incur higher production expenses. In particular, certified organic producers spend significantly more on labor expenses, insurance payments, and marketing charges than conventional farmers. The results suggest that early adopters of organic farmers have done so for non pecuniary reasons and the lack of economic incentives can be an important barrier...

ARE REVISIONS TO USDA CROP PRODUCTION FORECASTS SMOOTHED?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Isengildina,   Olga; Irwin,   Scott H.; Good,   Darrel L.
This study investigates the nature of the revision process of USDA corn and soybean production forecasts over the 1970/71 through 2002/03 marketing years. Nordhaus' framework for testing the efficiency of fixed-event forecasts is used. In this framework, efficiency is based on independence of forecast revisions. Both parametric and non-parametric tests reject independence of consecutive forecast revisions. Positive correlation and consistency of directional changes in forecast revisions suggest that these forecasts are "smoothed." Estimates of the impact of smoothing on forecast accuracy show that correction for smoothing may result in economically meaningful improvements in accuracy.

Are there customary rights to plants? An inquiry among the Baganda (Uganda), with special attention to gender
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Howard,   Patricia L.; Nabanoga,   Gorettie.
Debates around Common Property Resources and Intellectual Property Rights fail to consider traditional and indigenous rights regimes that regulate plant resource exploitation, establish bundles of powers and obligations for heterogeneous groups of users, and create differential entitlements to benefits that are related to social structures. Such rights regimes are important to maintaining biodiversity and to human welfare; failing to recognize them presents dangers. The case study investigates the gendered nature of informal rights to selected tree and plant species that are distinct from, but related to, customary rights to land and trees, and are embedded in cosmology and social norms.

Are U.S. Corn and Soybeans Becoming More Drought Tolerant?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Yu,   Tian; Babcock,   Bruce A.
An objective drought index that measures the dry and hot conditions adversely affecting crop yields is used in a regression analysis to test whether corn and soybeans have become more drought tolerant. Results indicate that corn yield losses, whether measured in quantity terms or as a percentage of mean yield, have decreased. The null hypothesis that the absolute level of soybean yield losses due to drought has not changed cannot be rejected. But yield losses in percentage terms have decreased over time. Because drought is the primary cause of yield loss in the U.S. crop insurance program and because U.S. crop insurance rates assume that percentage of yield losses are constant over time, these results indicate that U.S. crop insurance rates in the Corn...

Increasing volumes and speed of agricultural trade and the opening of new markets for agricultural products create greater challenges to systems established to protect countries from invasive organisms that can be harmful to human and animal health, crops and natural environments. In reaction to the threat of exotic pests and diseases, the World Trade Organization recognises the right of country members to protect themselves from the risks posed by exotic pests and diseases through the application of Sanitary and Phytosanitary (SPS) measures. One possible response from exporting countries facing SPS trade barriers is to obtain pest-free area (PFA) certification. While large benefits can potentially be achieved from greater access to world markets through...

ARPA Subsidies, Unit Choice, and Reform of the U.S. Crop Insurance Program
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Babcock,   Bruce A.; Hart,   Chad E.
The Agricultural Risk Protection Act (ARPA) has largely met its objectives of inducing farmers to increase their use of the crop insurance program. Both insured acreage and coverage levels have increased dramatically in response to ARPA's large increase in premium subsidies. An unintended consequence of the larger subsidies is a dramatic increase in the incentive for farmers to insure their crops under optional units, that is, insurance at the field level rather than at the farm or crop level. The expected rate of return to farmers who choose to invest additional premium dollars to move to optional unit coverage ranges from a low of 61 percent at the 85 percent coverage level to 144 percent at the 65 percent coverage level. This explains why the majority...

Despite growing attention to crop and property damage caused by the Asian elephant, uncertainty exists about the magnitude of this problem. This paper explores the nature and magnitude of this problem of Sri Lanka. An economic analysis of individual farmers’ decisions to control elephants is provided. Government policies to assist farmers to cope with the elephant pest problem are assessed. Appropriate compensation schemes for farmers are seen as potentially more effective for conserving elephants in Sri Lanka than legal prohibitions on killing of elephants. Issues raised have wider relevance than merely to Sri Lanka or Asian elephants.

A controversa presença da cana nos assentamentos rurais nos últimos anos exige uma cuidadosa reflexão sobre sua interferência no modo de vida dos assentados e na relação dos assentamentos com a dinâmica do desenvolvimento regional. A presença da cana nos assentamentos tem suscitado ao longo desse período conflitos internos, discussões, nada consensuais, sobre o passado/ presente/ futuro dessas experiências. A análise da parceria com as agroindústrias é atravessada, do nosso ponto de vista, pela noção de trama de tensões. Nos termos em que a parceria vem se concretizando, temos discutido a necessidade de desconstrução desse conceito calcado na matriz teórica de capital social e a importância de submeter ao crivo analítico as desigualdades constitutivas...

In general, reported rates of return to agricultural R&amp;D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil. Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output. If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&amp;D spending, the...

Assessing Economic and Environmental Impacts of Ethanol Production on Fertilizer Use in Corn Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nehring,   Richard F.; Vialou,   Alexandre; Erickson,   Kenneth W.; Sandretto,   Carmen L.
The share of corn used in ethanol production has been growing rapidly. USDA predicts that more than 30 percent of the corn crop will be used for ethanol production in 2009/2010. Expanded corn acreage contributes to the application of more fertilizer and is likely to introduce a larger volume of nutrients into the environment. This study found that an increase in ethanol production is consistent with a significant increase in quality-adjusted fertilizer use in selected corn states.

The paper develops a mathematical programming model for assessing the impact of Environmental Policy instruments on French winegrowing farm’s adoption of pesticides-saving technologies. We model choices with regards to investment in precision farming and plant protection practices, in a multi-periodic framework with sequential decision, integrating uncertainty on fungal disease pressure and imperfect information on equipment performance. We focus on recursive models maximizing a Utility function. These models are applied on a representative sample of 534 winegrowers from the French Farm Accountancy Data Network (FADN). As expected, both ecotaxes and green subsidies make precision farming equipment more profitable, but the investment rate remains however...

ASSESSING KOSOVO'S HORTICULTURAL POTENTIAL - THE MARKET FOR FRUIT AND VEGETABLES ON THE BALKANS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fischer,   Christian.
SUMMARY Kosovo had been a net exporter – at least of some – fruit and vegetables in the former Federal Republic of Yugoslavia before the civil war. Current reconstruction efforts therefore focus on restoring the past horticultural potential of the now independent province. This paper analyses the competitiveness of the Kosovar fruit and vegetable sector. By calculating average net trade flows during 1996-2000 for more than 20 individual fruit and vegetables and seven ag-gregates, demand potentials for the Balkan regional market are identified for potatoes, lettuce, garlic, dried beans and pears. In addition, average export unit values are calculated as price proxies in order to assess export price competitiveness in the region. While demand potentials for...

Deficiencies of micronutrients such as vitamin A are widespread, expecially in Africa. Biofortified crops such as maize, bred for high levels of provitamin A might offer a solution, but these crops are often bright orange, and African maize consumers prefer white. To estimate the consumers interest in orange biofortified maize, sensory evaluations were organized in rural Ghana with white, yellow and orange maize. The effect of information on willingness to pay for biofortification was estimated using a simulated radio message. Results indicate that color preferences are highly regional, wide variation exist within regions, and the provision of information is able to change these preferences. The color of biofortified maize should therefore not be seen as...

Assessing the benefits of research expenditures on maize production in South Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Townsend,   Rob F.; van Zyl,   Johan; Thirtle,   Colin G.
This paper focuses on assessing the benefits of research expenditures on maize production in South Africa. Both the production and supply function approaches are used to calculate elasticities of research expenditure on output and yield. Cointegration is used to establish long-run relationships between variables in these models. The lag structure of R&amp;D expenditures on output is examined making use of the unrestricted, polynomial, beta and gamma distributions. The coefficients of these lag distributions were then used to calculate a rate of return to maize research expenditure, which was estimated as being between 28% and 39% per annum. These rates of return are high, mitigating in favour of more research expenditure rather than less.

The main objective of this study is to evaluate the comparative advantage of olive oil production in Albania using Policy Analysis Matrix (PAM) method. The result indicates that olive oil production in Albania is profitable for the producers. Whereas the DRC ratio equals to 2.2, meaning that olive oil production in Albania does not have a comparative advantage for the given situation of production, prices and technology. This means that while it is profitable for private producers to manufacture olive oil for the domestic market, it does not have a comparative advantage with other EU countries. In order for Albania to develop an olive oil industry comparable to neighboring countries with similar climatic and soil conditions, the country will need to...

ASSESSING THE COMPETITIVENESS OF INDIAN COTTON PRODUCTION: A POLICY ANALYSIS MATRIX APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mohanty,   Samarendu; Fang,   Cheng; Chaudhary,   Jagadanand.
This paper uses a modified policy analysis matrix (PAM) approach to assess the efficiency of cotton production in five major producing states in India. The results indicate that cotton is not efficiently produced in the second-largest cotton-producing state in the country. Without government interventions in this state, it is likely that acreage will move away from cotton to more profitable crops such as sugarcane and groundnut. In addition, we conclude that cotton is not the most efficiently produced crop in the other four states; however, there is at least one crop in each state that is less efficiently produced than cotton. These findings suggest that Indian policies directed at maintaining the availability of cheap cotton for the handloom and textile...

Autores: Targetti,   Stefano; Viaggi,   Davide; Cuming,   David; Sarthou,   J.P.; Choisis,   J.P.
Organic and low-input farming practices are considered keystones for the conservation of biodiversity in semi-natural systems. Accordingly, attention to the assessment of the benefits stemming from these activities is increasing in order to provide a solid base for the adoption of agro-environmental incentives and to support their monitoring and evaluation. The evaluation of the positive effects of organic and low-input farming activities on biodiversity is limited mainly by: the difficulty in proposing simple and widely-applicable indicators of biodiversity, and the substantial lack of data concerning the costs of measuring biodiversity - an essential element for a cost-effectiveness analysis. Moreover, the limited scientific literature available is based...

ASSESSING THE ECONOMIC IMPACTS OF INTEGRATED PEST MANAGEMENT: LESSONS FROM THE PAST, DIRECTIONS FOR THE FUTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Swinton,   Scott M.; Williams,   Mollie B.
This paper reviews the literature assessing the economic impacts of integrated pest management (IPM).  Definitions of IPM are categorized as input- or outcome-oriented, and an outcome- oriented definition is recommended for public program assessment.  The literature on economic impact assessment of IPM is divided according to focus on expected profit, profitability risk, environment, and health.  Measuring diverse impacts on the environment and health poses a challenge, as does placing a value on those impacts.  Evaluation of environment and health variables has been accomplished either by comparing individual attributes (multiple criteria approach) or else by constructing a weighted index (index approach), which may be measured in monetary or non-...

Autores: Cai,   Ruohong; Bergstrom,   John C.; Mullen,   Jeffrey D.; Wetzstein,   Michael E.
In this paper, a dynamic optimization model was developed to simulate how farm-level realized price and profitability respond to yield change which was induced by climate change. Producers' acreage response was included in the dynamic model considering crop rotation effect. In the crop rotation model, a modified Bellman equation was used to dynamically optimize the net present value of farm profit for a five-year interval. This simulation process was repeated through the year 2050. Then yield, price, and acreage response were compiled to generate realized profit. Results generally indicated that reduction in crop yields due to climate change results in reduced farm profitability for most of the states studied. Predicted climate change is more likely to...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Aurbacher,   Joachim; Lippert,   Christian; Krimly,   Tatjana.
To assess the impact of climate change on agriculture in German districts, a Ricardian analysis accounting for spatial autocorrelation is used. The analysis relies on land rental prices from agricultural statistics and climate data from the network of German weather observation stations. The results of the cross-sectional analysis show a significant correlation between land rents and increasing mean temperatures, as well as (except for East Germany) a significant increase of land rents along with declining spring precipitation. Next, climate data from the regional climate model REMO are used to calculate local land rent changes under different IPCC scenarios for a time horizon between 2011 and 2040. The overall result is an increase in land rents which...

Assessing the Impact of Cowpea and Sorghum Research and Extension in Northern Cameroon
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sterns,   James A.; Bernsten,   Richard H.
Throughout Africa, per capita food production has been declining since the early 1960s. Cameroon has sought to counter this trend by increasing agricultural productivity through research and extension. In order to establish future investment priorities, policy makers need to know if past agricultural research investments have earned sufficient returns to justify continued funding. Further, national experiences need to be compared to see if returns varied across programs, and in cases where they did, explanations need to be sought to discover why these variations exist. To address these issues, data were collected in Cameroon and analyzed in order to estimate the benefits and costs of investments in sorghum and cowpea research and extension in northern...

This study is part of a larger effort to explore the impact of agricultural research on poverty reduction. It examines the diffusion and impact of hybrid maize in selected resettlement areas of rural Zimbabwe, paying particular attention to varieties made widely available from the mid-1990s onwards. While “Zimbabwe’s Green Revolution” of the early 1980s was characterized by the widespread adoption of hybrid maize varieties and significant increases in yields, the subsequent diffusion of newer varieties occurred more slowly and had a more modest impact. Several factors account for this. Government now plays a much-reduced role and one that increasingly focuses on “better farmers.” Private-sector institutions that have entered the maize sector operate mainly...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Laxmi,   Vijay; Erenstein,   Olaf.
A conservative ex-ante assessment of supply-shift gains alone (excluding social and environmental gains), shows that the investment in zero tillage (ZT) R&amp;D by the Rice-Wheat Consortium and CIMMYT was highly beneficial with a benefit-cost ratio of 39, a net present value of US$ 94 million and an internal rate of return 57%. Sensitivity analysis highlights the influential role of the yield gain, the contribution of reduced tillage (i.e. partial adoption) and the assumed time-lag. Significant positive spillovers of sunk ZT R&amp;D costs – both previous and from elsewhere - also contributed to the high returns. The case thereby highlights the potential gains from successful technology transfer and adaptation. The case however also underscores that...

ASSESSING THE IMPACT OF THE EXCHANGE RATE AND ITS VOLATILITY ON CANADIAN PORK AND LIVE SWINE EXPORTS TO THE UNITED STATES AND JAPAN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fabiosa,   Jacinto F.
A model of a representative Canadian pork exporter is developed to examine the impacts of the exchange rate and its volatility on pork and live swine exports. The pork export supply equation is expressed as a function of the expected level of real exchange rate and a time-varying variance of real exchange rate. An AR(p) model is used to represent the expected real exchange rate, and a GARCH(p, q) model is used to generate the time-varying variance. The same model is used to examine the sensitivity of pork exports to Japan from Canada, the United States, and Denmark. The parameters of all pork and live swine export equations have theoretically consistent signs and many are significant. That is, the domestic price in the exporting country has a negative...

ASSESSING THE IMPACTS OF CLOSING THE RIVER GULF GRAIN COMPANY ON LOCAL PRODUCERS OF CORN AND SOYBEANS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carriquiry,   Miguel A.; Babcock,   Bruce A.
Hotelling's classic model of spatial competition is used to estimate the impacts on price of the closure of one of three grain buyers on the Mississippi River in the vicinity of Scott County, Iowa. The customers of the buyer who is closing (River Gulf Grain Company) in Davenport, Iowa, are assumed to deliver their grain to a buyer in either Buffalo, Iowa, to the south or to a buyer in Clinton, Iowa, to the north. Calibration of Hotelling's framework to this situation leads to an estimated decline in grain bids of 1.5¢ per bushel for the buyer located in Clinton and by 2.5¢ per bushel for the buyer located in Buffalo. These estimates are based on an incremental transportation cost of 0.15¢ per mile between the seller's farm and the buyer. This price decline...

Autores: Pantzios,   Christos J.; Rozakis,   Stelios; Tzouvelekas,   Vangelis.
Utilizing the stochastic frontier approach, this paper estimates output and input-oriented technical and scale efficiency levels for a sample of cotton-growing farms in Thessaly, Greece. The empirical results suggest that Greek cotton farm operations are technically and scale inefficient. There is a considerable scope for improvement in resource use and thereby in farm income of cotton farms; Greek cotton farmers could reduce production costs by 20.4%, making more efficient utilization of the existing production technology. Factors responsible for the technical efficiency differentials observed among cotton-growers include the farmer's age and education as well as the farm's land fragmentation and output specialization.

While agricultural production statistics are reported on a geopolitical – often national - basis we often need to know the status of production or productivity within specific sub-regions, watersheds, or agro-ecological zones. Such re-aggregations are typically made using expert judgments or simple area-weighting rules. We describe a new, entropy-based approach to making spatially disaggregated assessments of the distribution of crop production. Using this approach tabular crop production statistics are blended judiciously with an array of other secondary data to assess the production of specific crops within individual ‘pixels’ – typically 25 to 100 square kilometers in size. The information utilized includes crop production statistics, farming system...

The economic reforms in maize marketing and trade policies implemented during the 1990s have been highly controversial, and there remains a lack of solid empirical investigation on the impacts of these reforms on national food security, price stability and rural income growth. This study aims to provide a detailed evidence-based analysis of the impacts of maize marketing and trade policies on smallholder agricultural production growth, access to food by consumers, and other important national policy objectives. These insights from Zambia can hopefully move forward the continuing debate in the region on how maize marketing and trade policies should be structured in the future.

Market shares are estimated by product for geographic areas supplying Nairobi, and for each important wholesale and retail market in the city. It is found that horticultural production for the domestic market is keeping up with rural population growth but not with the much faster urban population growth. The urban wholesaling and retailing system has decentralized dramatically and with little planning over the past two decades in response to lack of...

Assessment of the effectiveness of maize seed assistance to vulnerable farm households in Zimbabwe
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Langyintuo,   Augustine S.; Setimela,   Peter S.
The publication describes outcomes of a study to assess the effectiveness of a large-scale crop seed relief effort in Zimbabwe during 2003-07. Aims of the effort, which was supported by the British Department for International Development (DfID) and coordinated by the Food and Agricultural Organization (FAO) regional office in Harare, included broader diffusion of open-pollinated maize varieties (OPVs), as opposed to hybrids. Based on the findings of the study, the authors recommend that, to increase benefits to vulnerable groups, participants in such efforts should effectively disseminate information on selecting and recycling seed, supported by training and field demonstrations, and should target relatively well-endowed farmers initially. Recommendations...

Autores: Kabwe,   Stephen; Donovan,   Cynthia; Samazaka,   David.
This research focuses on the performance in the Magoye ripper in maize and cotton production in Eastern and Southern Provinces during the 2004/2005 productions year. Findings include the following: In maize production, the ripper enabled higher yields compared to traditional animal ploughing, by increasing the effectiveness of nitrogen fertilizer applications, resulting in net profits per hectare of ZK575,800 in Eastern Province and ZK93,800 in Southern Province; In cotton, the input applications and size of fields were the most important determinants of yield, and the ripper had no significant individual effect. Farmers using the ripper indicated that it helped conserve water, enabled early land preparation and early planting; and Farmers not using their...

Assessment of the Farm Level Financial Profitability of the Magoye RipperiIn Maize and Cotton Production in Southern and Eastern Provinces
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kabwe,   Stephen; Donovan,   Cynthia; Samazaka,   David.
With the risk of the drought in the agricultural production areas of Zambia, conservation farming (CF) was introduced as a set of technologies that can improve productivity while reducing plant stress due to moisture constraints. Under animal traction, CF involves using the Magoye ripper to minimize soil disturbance in land preparation and to help improve water conservation, thus enhancing farmers’ land and labor productivity. This technology has been promoted by Golden Valley Agricultural Research Trust (GART) and other stakeholders in the agricultural sector in Zambia and shows promise in on-station and on-farm trials.  This research is based on actual farmer use of the ripper in Eastern and Southern Provinces in 2004/2005, a year with erratic rainfall...

Assessment of two alternative switchgrass harvest and transport methods
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Popp,   Michael P.; Hogan,   Robert J., Jr.
As the search for renewable energy sources from agriculture intensifies, many agricultural producers are contemplating production of a native perennial grass species, switchgrass (Panicum Vigratum, L.). While much information on various aspects of switchgrass production exists, this paper discusses implications of two alternative harvesting and transportation methods that may be suitable for Arkansas conditions. Results suggested that module building compared to the simpler round baling technology may be a promising alternative.

ASSESSMENTS OF THE RELATIVE VALUES OF COMPOUND NITROGEN-PHOSPHORUS FERTILIZERS FOR WHEAT PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Colwell,   J.D.
A general procedure is developed for calculating optimal rates of application of compound fertilizers, containing several nutrients in fixed composition. The calculations are based on response surface models that have been obtained with single nutrient fertilizers. The relative values of alternative compounds can be assessed from the increases in profit that result from their use at optimal rates and this is preferable to simply comparing fertilizer compositions with that of an ideal mix of single nutrient fertilizers. The relative values of a range of standard nitrogen-phosphorus fertilizers are assessed for wheat production in southern New South Wales. The results indicate the need for a compound with a low nitrogen/phosphorus ratio of about 0.5. For the...

Assisting decision-making in Queensland barley production through chance constrained programming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gali,   Jyothi; Brown,   Colin G.
A chance constrained programming model is developed to assist Queensland barley growers make varietal and agronomic decisions in the face of changing product demands and volatile production conditions. Unsuitable or overlooked in many risk programming applications, the chance constrained programming approach nonetheless aptly captures the single‐stage decision problem faced by barley growers of whether to plant lower‐yielding but potentially higher‐priced malting varieties, given a particular expectation of meeting malting grade standards. Different expectations greatly affect the optimal mix of malting and feed barley activities. The analysis highlights the suitability of chance constrained programming to this specific class of farm decision problem.

ASYMMETRIC GRADING ERROR AND ADVERSE SELECTION: LEMONS IN THE CALIFORNIA PRUNE INDUSTRY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chalfant,   James A.; James,   Jennifer S.; Lavoie,   Nathalie; Sexton,   Richard J.
Grading systems are often introduced to address the classic adverse selection problem associated with asymmetric information about product quality. However, grades are rarely measured perfectly, and adverse selection outcomes may persist due to grading error. We study the effects of errors in grading, focusing on asymmetric grading errors- namely when low-quality product can erroneously be classified as high quality, but not vice versa. In conceptual model, we show the effects of asymmetric grading errors on returns to producers. Application to the California prune industry shows that grading errors reduce incentives to produce more valuable, larger prunes.

ASYMMETRIC PRICE TRANSMISSION IN THE ISRAELI CITRUS EXPORT SECTOR IN THE AFTERMATH OF LIBERALIZATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Goetz,   Linde; von Cramon-Taubadel,   Stephan.
The Israeli citrus export sector was liberalized in 1991 with the aim to increase citrus growers’ income and to improve overall efficiency of the international citrus marketing channel. However, the former government export monopoly’s activities were mainly taken over by four large companies accounting for over 90% of total Israeli citrus market exports. In addition, citrus exporters maintained the monopoly’s consignment system, substantially limiting transparency on how the grower price is determined. This lead the government to intervene in the newly liberalized market by implementing a minimum price agreement in the 1994/95 season to protect citrus growers against exporters’ abuse of market power. In this paper we analyze whether market power was...

Atrazine: Environmental Characteristics and Economics of Management
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ribaudo,   Marc; Bouzaher,   Aziz.
Restricting or eliminating the use of atrazine in the Midwest would have important economic consequences for farmers and consumers. Atrazine is an important herbicide in the production of corn and other crops in the United States. Since atrazine is such an important herbicide, mandatory changes in application strategies are likely to generate sizable costs for producers and consumers. However, recent findings indicate that elevated amounts of atrazine are running off fields and entering surface water resources. This report presents the costs and benefits of an atrazine ban, a ban on pre-plant and pre-emergent applications, and a targeted ban to achieve a surface water standard. A complete atrazine ban is hypothesized to be the costliest strategy, while the...

The Australian Agricultural Council and its Standing Committee on Agriculture have recently paid considerable attention to methods of increasing rural output in Australia and of expanding wheat production in particular. One of the problems at the forefront of discussion has been that of the provision of adequate incentives, designed to encourage farmers to intensify their production programmes.  It is clear that detailed factual information on the attitudes and expectations of farmers is essential to the satisfactory formulation of suitable incentives and of policy generally. As a contribution to an understanding of the wheat farmers' problems, attitudes and expectations, the Commonwealth Bureau of Agricultural Economics and the Division of Marketing and...

Autores: McKenney,   Daniel W.
The Australian Centre for International Agricultural Research (ACIAR), through collaborative projects with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia, and the Chinese Academy of Forestry (CAF), has been involved in tree species selection trials in southern China since 1984. The trials were aimed at identifying fast-growing species of Eucalyptus, Acacia and Casuarina. The Chinese have been planting Australian tree species for more than 100 years, but before the ACIAR project there had been little progress in determining which species and provenances would be best for the local climate and soils. This paper presents an assessment of the economic impact of research undertaken under two ACIAR-supported projects....

Autores: Gomann,   Horst.
The proposals for reforming the Common Agricultural Policy within the Mid Term Review of the European Commission fueled the discussion about the future of direct payments to farmers. The EU Commission recommends a decoupling of animal and area payments from the production by granting these direct payments as a payment claim per hectare of eligible farm land. However, introducing area tied payments the intended shift of payments “from the produce to the producer” will not take place, but instead an increased transfer of payments to land owners seems likely. This study therefore analyses the impacts of changing the area payments for grand cultures into person-tied payments on the cereals market of the European Union. For the assessment of impacts homogenous...

Those farming alternatives are shown in the paper that are based on different chemical use in plant production. It is investigated how the profitability will change when we make changes in former farming activity, and what should be changed to reach income turning to organic faming or precision farming. In developing countries the main question is to produce the essential food demand, but it is necessary to examine the existence of fundamental important factors, the costs...

A Nyugat-dunántúli Régió gazdálkodói körében vizsgáltuk az energetikai növények ismertségét, a termelés megítélését és az alacsony vállalkozói aktivitás okait. Avezetők csupán 7%-a hallott az összes megjelölt energianövényről, míg 11% még egyikkel sem találkozott. Azok a vezetők, akik bizonyos szintű ismerettel már rendelkeznek a vizsgált energianövényekről, nagyobb érdeklődést mutatnak az átlagnál. Az információk elérhetőségével a válaszadók 29%-a elégedetlen és 53%-a közepesen elégedett. Avárható támogatásoktól és a realizálható árbevételtől függ alapvetően az energianövények termelésére való vállalkozás, de fontos még a felvásárlási szerződés és a feldolgozóüzem távolsága is. Asaját üzemi felhasználás lehetősége csak közepes minősítést kapott. A...

Az ökológiai gazdálkodás költség-jövedelem viszonyait a hagyományos termeléssel összehasonlítva, modellszámítások alapján vizsgáltuk. A modellépítéshez szükséges adatokat Hortobágy térségében működő egyéni gazdálkodók körében gyűjtöttünk. Az egy hektárra jutó költségek összegében a két gazdálkodási mód között jelentőseltérések nem voltak, a költségek szerkezete azonban markáns különbségeket mutatott, amely a technológiák eltéréseivel magyarázható. Az ökológiai növénytermelésben a hozamok jellemzően alacsonyabbak voltak, az önköltség és az értékesítési árak viszont magasabbak. Egyik termelési mód sem bizonyult életképesnek támogatások nélkül, a bruttó jövedelem különbségeit azonban nem a támogatások, hanem elsősorban az eltérő hozamok és értékesítési árak...

The significance of organic farmlands can be evaluated in two ways: based on their ecological and their economic implications. Regarding the former, it does not make a crucial difference how the land is utilised specifically: pasture and meadow; arable land or plantation or certified organic farmland, use not known. For an illustration, let us consider that in 2005, almost half of organic farmlands in the world were located in Australia, amounting to over 31 million hectares. Most of this area is pastoral land for low intensity grazing in Australia. Therefore, one organic hectare in Australia is not directly equivalent to one organic hectare in Denmark, for example, due to its level of productivity. As a result, it is worthwhile to survey the exact extent...

Az öntözés egyik alapvető célja, hogy javítsa az egyre növekvő népesség élel-miszerrel való ellátását. A világon jelenleg a szántóterület 17%-át öntözik, vi-szont ez a felület adja az évenként betakarítható össztermés valamivel több mint 40%-át. Hazánkban a vízjogi engedéllyel rendelkező öntözésre berendezett terü-letünk 210 ezer hektár, ami a szántóterület közel 5%-a, de a ténylegesen öntözött terület évjárattól függően ennek kb. a fele. Az Európai Unióban átlagosan a szántóterület 13,5%-a tekinthető öntözöttnek. Az elkövetkező évek alapvető fejlesztési feladata a már meglévő öntözőrend-szerek felújítása és bővítése.

Az öntözéses gazdálkodásról a Tisza-tó és a nagykunsági öntözőrendszert ellátó főcsatorna átadásának 30. évfordulóján
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lengyel,   Lajos.
Az öntözés mint agrotechnikai tényező a mezőgazdasági termelés intenzifi kálásának egyik eszköze és lehetősége. Bevezetése többletberuházással, nagyobb ráfordításokkal oldható meg. Öntözéssel a természetes csapadékellátás ingadozásai csökkenthetők, a termelés biztonsága és a hozamok növelhetők. Alkalmazását az üzemi feltételek és célok mellett makrogazdasági és klimatikus hatások is indokolják. Az elmúlt fél évszázad hazai öntözésfejlesztésében a Tiszalöki, a Kiskörei Vízlépcső és Öntözőrendszerei tervezése, kivitelezése és működtetése napjainkban is sok hasznosítható tanulsággal és tapasztalattal szolgál, mint például a komplex szemléletű térségi, üzemi vízgazdálkodás és öntözésfejlesztés, az állami beavatkozás a tervek összehangolásától az üzemi...

Az őszi árpa klimatikus igényei és az éghajlatváltozás
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Novak,   Aliz; Erdelyi,   Eva.
Munkánkban összehasonlító vizsgálatokat végeztünk az őszi árpa fejlődési szakasza¬inak klimatikus igényeiről. A becsült meteorológiai jellemzők átlagosan nem mutatnak nagy változást a közeljövőre – jóllehet a század végére már igen –, de eloszlásuk alakulása a mezőgazdaságban komoly következményekkel járhat. A növény szempontjából azonban az éves és havi átlaghőmérséklet, illetve csapadékösszegek elemzése helyett sokkal több információhoz juthatunk, ha a növény fejlődési szakaszait külön-külön vizsgáljuk. Végigkövetve a növény fejlődési szakaszait megállapítható, hogy az őszi árpa klimatikus igényei várhatóan a jövőben is teljesülnek, jóllehet a termésbiztonság ezzel együtt romlani fog.    ----------------------------------------    This paper covers...

Az őszi árpa terméskockázatának növekedése és lehetséges okai
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Erdelyi,   Eva; Novak,   Aliz; Ladanyi,   Marta.
Az éghajlatváltozás folyamata már elkezdődött, ezért a magyar agrárkutatóknak és szakembereknek is jól működő leíró-előrejelző rendszereket szükséges alkotniuk. Munkánk célja a hozamok elemzése, az időbeni változások megfigyelése volt 1951-től napjainkig. Az árpa termésmennyiségi adatait a trendhatások kiszűrésével összehasonlíthatóvá tettük. A vizsgálat helyszíne Hajdú-Bihar megye volt. Az ún. E,V hatásossági kritérium alapján vizsgáltuk az árpa terméskockázatának alakulását az 1951-90-es időszakban, továbbá azóta. A kimutatott terméskockázat-növekedés azt a nézetet támasztja alá, hogy az éghajlat „láthatóan” változik, aminek jeleivel szinte naponta találkozunk. Megfigyelt meteorológiai változókból olyan indikátorokat ké¬pezhetünk, amelyek vélhetően...

Autores: Reder,   Orsolya; Csatai,   Rozsa; Salamon,   Lajos.
Magyarország talajainak jelentős része rézhiányos, így a három legfontosabb makrotápanyag (N, P, K) mellett az esszenciális mikroelemekre, köztük kiemelten a rézre is egyre nagyobb figyelmet szükséges fordítani. Ennek érdekében réz-mikroelem trágyákkal történő kisparcellás őszi búza lombtrágyázási kísérletekben három réztartalmú lombtrágya (réz-amin komplex, réz-szénhidrát komplex és réz-amin ioncserélt szintetizált zeolit) hatását vizsgáltuk az őszi búza hozamára és hasznára. Kisparcellás kísérleteinknél két fenológiai fázisban (bokrosodáskor és virágzáskor) történt a szerek kijuttatása különböző dózisok alkalmazásával, három éven keresztül. Az elvégzett kísérletek alapján a réz-mikroelem trágyás kezelés a minőség javulása mellett a hozamok emelkedésén...

Background Information on the Chinese Fruit Sector
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Thornsbury,   Suzanne; Woods,   Mollie.
The People's Republic of China was established in 1949, ushering in an era of socialism and government centralization. Beginning in 1978, China's economy gradually transitioned from centralization to the transitional and somewhat more privatized society of today. Prior to 1978, government policies aimed at controlling food supplies and prices were common. Food rationing in 1953 was aimed at guaranteeing food for urban dwellers and included price administration by the government (Dong and Fuller, 2006). Agricultural productivity and the availability of food increased dramatically when laws that decentralized agricultural production were enacted in 1981. Food rationing and market centralization were abolished later in urban areas for non-staple food items,...

BANANA CULTIVAR TRIALS FOR FRUIT PRODUCTION, ORNAMENTAL-LANDSCAPE USE, AND ORNAMENTAL-NURSERY PRODUCTION IN SOUTH GEORGIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fonsah,   Esendugue Greg; Krewer,   Gerard; Rieger,   Mark.
North America is the largest net importer of bananas on a regional basis. The United States is still the world’'s number- one importer and consumer of bananas. U.S. companies spend approximately $1.1 billion each year on banana imports, purchasing 31.1% of total world imports (Fonsah 2002; FAO 2001). Bananas and plantains together have been rated the fourth most important crop in the world in terms of food value and food security. This research is aimed at determining the feasibility and suitability of Annual Cropping Production (ACP) for a niche market under Georgia weather conditions and, determining which cultivars have the greatest potential for ornamental-landscape use and ornamental-nursery production. Phenological and pomological sampling and data...

Banana policy: a European perspective
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tangermann,   Stefan.
European Union banana policies do not make economic sense, and hence criticism of these policies is justified. Some facts should, though, be remembered. If the EU had chosen free trade in bananas when the Single Market was established, certain producers both inside and outside the EU would have lost income, and it proved politically impossible to choose direct financial compensation. Also, the quantitative implications of the new EU banana regime may be less than sometimes assumed, as trade has not been reduced very much. The WTO's role is not to judge the economic merits of these policies, but their legal justification.

Banana Supply Chains in Indonesia and Australia: Surviving Isolation from End markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Singgih,   Shinta; Woods,   Elizabeth.
Two banana supply chains (BSC), one in Indonesia (BSC1) and one in Australia (BSC2), are described based on case study research conducted in 2002. BSC1 sources bananas from small farmers for distribution through traditional markets in Jakarta. BSC2 includes farmers supplying to both major and independent retailers in Sydney through a wholesale agency with some farmer ownership. Farmers in both chains live in relative isolation from the main markets for their bananas. Prices for their bananas depend on the market prices in the city, upon which they have little control. This paper focuses on how farmers removed from key markets, deal with buyers to receive fair prices. In both chains, most transactions between farmers and their buyers were completed through...

Banana Value Chains in Central Africa: Constraints and Opportunities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ouma,   Emily Awuor; Jagwe,   John.
Smallholder farmers in developing countries need to improve their position in food value chains in order to improve their margins and as a strategy for coping with agricultural food price volatility through innovations within the chains. Value chain mappings and gross margin analysis were employed to assess constraints and opportunities for existing value chains for bananas in Central Africa using market survey data. The results showed weak linkages within the banana value chains with poor integration of value chain actors and minimal involvement with regional markets and high-value domestic chains such as supermarkets. Value addition in terms of agroprocessing was carried out at small scale levels using rudimentary techniques limiting the final product to...

Bayes Estimates of Time to Organic Certification
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hattam,   Caroline; Holloway,   Garth J.
The adoption of organic production has increased dramatically over recent years, especially in less developed countries. However, little information is available about who adopts, the difficulties they face in converting and how these factors vary over time. Using small-scale avocado producers (&lt;15ha) from Michoacán, Mexico as a case study, this paper explores the factors affecting the time-to-adoption of organic production and certification, drawing from five parametric descriptions of the data. These models are implemented using a Bayesian approach and advances in Markov chain Monte Carlo methods. The results indicate that additional sources of income, together with membership of producers’ associations, higher levels of education and experience of...

Bayesian Estimation of Technical Efficiency of a Single Input
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kurkalova,   Lyubov A.; Carriquiry,   Alicia L.
We propose estimation of a stochastic production frontier model within a Bayesian framework to obtain the posterior distribution of single-input-oriented technical efficiency at the firm level. The proposed method is applicable to the estimation of environmental efficiency of agricultural production when the technology interaction with the environment is modeled via public inputs such as soil quality and environmental conditions. All computations are carried out using Markov chain Monte Carlo methods. We illustrate the approach by applying it to production data from Ukrainian collective farms.

Behavior of subsistence producers in response to technological change- The elasticity of cassava production and home consumption in Benin
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Takeshima,   Hiroyuki.
The welfare effects of GM (genetic modification)-led productivity growth for cassava producers are partly affected by the characteristics of individual cassava producing households. Those household characteristics include the elasticity of production and home consumption of cassava. Some studies assume the inelastic home consumption when conducting ex-ante welfare effects analysis for subsistence crops. This study modifies the estimation methods used in the past literature to estimate both elasticities using the dataset from Benin. Several assumptions are also tested regarding the heterogeneity of cassava producers. On estimation of elasticities, the paper tests the hypothesis that on-farm sellers are characteristically different from off-farm sellers by...

Benefit-Cost Analysis and Socio-Economic Considerations of Trypanosomiasis Control and Treatment in Northern Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wahab,   S.; Asuming-Brempong,   Samuel.
The paper estimates the cost of tsetse control and treatment of trypanosomiasis and the benefits involved, using benefit-cost analysis. It also estimates the extent to which socio-economic characteristics of farmers affect the use of tsetse control techniques, using a maximum Likelihood-Binary Logit model. The results show that farmers will benefit if they invest in control and treatment of the disease. We find that the farmer accepting the challenge that the tsetse fly is a threat to cattle production, the number of dependants the farmer has, and the farmer agreeing that the bite of the tsetse fly causes the nagana disease are significant factors that affect adoption of control practices including the use of prescribed drugs. Our findings suggest that...

Benefit-Cost Analysis of Uganda’s Clonal Coffee Replanting Program: An Ex-Ante Analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Benin,   Samuel; You,   Liangzhi.
The Ugandan coffee industry is facing some serious challenges, including low international prices in the international coffee market, aging coffee trees and declining productivity, and, more recently, the appearance of coffee-wilt disease, which have all contributed to the decline in both the quantity and value of coffee exports. The government of Uganda, through the Uganda Coffee Development Authority (UCDA), in 1993/94 started a coffee-replanting program to both replace coffee trees that were old or affected by coffee-wilt and expand coffee production into other suitable areas in northern and eastern Uganda. This program seems to be helping to both combat the industry’s problems and reverse the declining trends. However, the UCDA announced in 2004 that...

Best fit model selection for spatial differences (regression) in the profitability analysis of precision phosphate (P) application to winter cereals in Precision Agriculture (PA)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hough,   Ella Christina; Nell,   Wilhelm T.; Maine,   Ntsikane; Groenewald,   Jan A.; van der Rijst,   M.
Phosphates (P) are an important nutrient required by every living plant and animal cell, and deficiencies in soils could cause limited crop production, thereby reducing profitability. Phosphates are also a primary nutrient essential for root development and crop production, and are needed in the tissues of a plant where cells rapidly divide and enlarge. Precision agriculture (PA) could assist the farmer in applying the correct amount of P to the part of the field where it is required most. Variable rate technology (VRT) is a potential tool that can help with the development of strategies for phosphate fertilizer management. On-field trials were conducted on a commercial farm in the Western Cape Province; As many as five soil types occur on each field...

Best Management Practices: How Economical is it in Southern Agricultural Systems?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Matekole,   Augustus N.; Westra,   John V.; Appelboom,   Timothy W.
Conventional drainage systems tend to aggravate runoff and nutrient leaching problems on farms especially during the off-season. This study uses a biophysical economic model to identify, evaluate and determine multifunctional benefits of implementing and establishing nitrogen rate fertilizer application and conservation tillage practices as best management practices (BMPs) in the lower Mississippi River Basin (MRB). Simulation results showed that agricultural producers generally preferred no tillage to conventional tillage in reducing nutrient runoffs from fields because of higher net revenue per acre. Finally, given nitrogen runoff restrictions, farmers reduced crop acreage and nitrogen fertilizer application rates to help minimize losses.

Best Management Practices to Enhance Water Quality: Who is Adopting Them?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ghazalian,   Pascal L.; Larue,   Bruno; West,   Gale E.
This study investigates the determinants affecting producers’ adoption of some Best Management Practices (BMPs). Priors about the signs of certain variables are explicitly accounted for by testing for inequality restrictions through importance sampling. Education, gender, age, and on-farm residence are found to have significant effects on the adoption of some BMPs. Farms with larger animal production are more apt to implement manure management practices, crop rotation, and riparian buffer strips. Also, farms with larger cultivated acres are more inclined to implement herbicide control practices, crop rotation, and riparian buffer strips. Belonging to an agro-environment club has a positive impact for most BMPs.

Betting on cotton: Potential payoffs and economic risks of adopting transgenic cotton in West Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Falck-Zepeda,   Jose Benjamin; Horna,   J. Daniela; Smale,   Melinda.
Cotton is the largest source of export receipts in several West African nations where yields are declining and pesticide use is rising. Although there may be payoffs to introducing genetically modified Bt (Bacillus thurigiensis) cotton, limited information is available to predict its potential economic impact and there is uncertainty about its performance. Recognizing these constraints, we use an economic surplus model augmented with stochastic simulation to estimate ex ante the impact and distribution of benefits from Bt cotton. We consider the effects of adoption on both yields and abating crop damage, and offer scenarios depicting the policy options faced by West African stakeholders. The findings indicate that although the total net benefits of...

Beyond semi-dwarf wheat yield increases: impacts on the Australian wheat industry of on-going spillovers from the International Maize and Wheat Improvement Center
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brennan,   John P.
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. While the initial impact came through the introduction of higher-yielding semi-dwarf wheat crops, those impacts have continued in the post-semidwarf period. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers from both the semi-dwarfs and the postsemidwarf phases have provided benefits to Australia averaging A $30 million per...

Biodiversity versus Transgenic Sugar Beet: The One Euro Question
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Demont,   Matty; Wesseler,   Justus; Tollens,   Eric.
The decision of whether to release transgenic crops in the EU is one subject to flexibility, uncertainty, and irreversibility. We analyse the case of herbicide tolerant sugar beet and reassess whether the 1998 de facto moratorium of the EU on transgenic crops for sugar beet was correct from a cost-benefit perspective using a real option approach. We show that the decision was correct, if households value possible annual irreversible costs of herbicide tolerant sugar beet with about 1 € or more on average. On the other hand, the total net private reversible benefits forgone if the de facto moratorium is not lifted are in the order of 169 Mio € per year.

Bio-ethanol Production from Wheat in the Winter Rainfall Region of South Africa: A Quantitative Risk Analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Richardson,   James W.; Lemmer,   Wessel J.; Outlaw,   Joe L.
Contrary to developments in other parts of the world, South Africa has not developed a bio-ethanol industry. The objective was to quantify the risks and economic viability of a wheat based bio-ethanol plant in the winter rainfall region of South Africa. Monte Carlo simulation of a bio-ethanol plant was used to quantify the risk that investors will likely face. Under the Base scenario a 103 million liter bio-ethanol plant would not offer a reasonable chance of being economically viable. Alternative price enhancing policies were analyzed to determine policy changes needed to make a bio-ethanol plant economically viable in the region.

Bioethanol production under endogenous crop prices: Theoretical analysis with an empirical application to barley
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rinne,   J.; Lankoski,   Jussi E.; Ollikainen,   Markku.
The European Union’s Emission Trading Scheme (EUETS) and the current renewable resource program provide strong incentives to use agricultural crops either for combustion in power plants to produce electricity and heat or as a feedstock for transportation fuels. In this paper we examine the social desirability of ethanol production from agricultural crops. To endogenize the competition on land use, we employ a Ricardian model of heterogeneous land quality, where land is allocated to alternative crops on the basis of their relative profitability. The model comprises three land use types: bioenergy crop, conventional feed crop and green setaside. Industry demands crops for both ethanol and feed production. Effects on the GHG balance are explicitly taken into...

Biofuel policies and the environment: the effects of biofuel feedstock production on climate, water quality and biodiversity
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lankoski,   Jussi E.; Ollikainen,   Markku.
In this paper we examine the multiple environmental effects of policies promoting biofuel production from agricultural crops. We develop theoretical and empirical frameworks and provide an integrated economic and ecological modelling approach: an economic model of farmers’ decision making is combined with a biophysical model predicting the effects of farming practices on crop yields and multiple environmental effects. The analysed environmental effects include GHG emissions over the life cycle, nitrogen and phosphorus runoff, herbicide runoff and the quality of wildlife habitats. Model is applied to crop production in Finland. We found that the overall environmental performance of alternative land use types is mainly driven by the value of CO2-eq emissions...

BIOFUELS AND LEAKAGES IN THE FUEL MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Drabik,   Dusan; de Gorter,   Harry.
Leakage in the fuel market differs, depending on whether ethanol production is determined by a tax credit or consumption mandate. Two components of market leakage are distinguished: domestic and international. Leakage with both a tax credit and a consumption mandate depends on market elasticities and consumption/production shares, with the former having a bigger impact. Leakage is also more sensitive to changes in market supply and demand elasticities in the country not introducing biofuels. Although positive with a tax credit, market leakage can be negative with a consumption mandate, meaning that one gallon of ethanol can replace more than a gallon of gasoline. We also show that being a small country biofuels producer does not necessarily mean that...

We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where...

Soybeans, the second highest cash crop following corn in the U.S., have come under attack by invasive species, the soybean aphid from the North and soybean rust from the South.  We estimated the economic losses resulting from soybean aphid infestation by using a dynamic equilibrium model.  Results indicate that, first, the reduction of soybean production resulting from soybean aphid infestation is largely absorbed by reducing soybean exports, due to the higher price elasticity of export demand compared to the domestic demand.  Second, the economic losses to U.S. soybean producers would grow on average annually between $12.8 million and $23.4 million during the first five years of infestation.  In the longer-run, soybean producers would suffer greater...

Autores: Egbendewe-Mondzozo,   Aklesso; Swinton,   Scott M.; Izaurralde,   R. Cesar; Manowitz,   David H.; Zhang,   Xuesong.
This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws upon biophysical crop input-output coefficients, price and cost data, and spatial transportation costs in the context of profit maximization theory. Yields are simulated using temperature, precipitation and soil quality data with various commercial crops and potential new cellulosic biomass crops. Three types of alternative crop management scenarios are simulated by varying crop rotation, fertilization and tillage. The cost of transporting biomass to a specific...

This paper seeks to understand the main sources of uncertainty in assessing the impacts of climate change on agricultural output, international trade, and poverty. We incorporate biophysical uncertainty by sampling from a distribution of productivity shocks reflecting the impacts of climate on agricultural yields in 2030. These shocks, in turn, affect the global economy. The response of economic agents to climate change is the second source of uncertainty in our estimates. We find that, even though it is difficult to predict where in the world agricultural crops will be favorably affected by climate change, we find that the responses of output and exports can be far more robust. This is due to the fact that supply and demand decisions depend on relative...

Biophysical Modelling and Performance Measurement
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Graham,   Mary.
Agricultural production, by its nature, impacts both positively and negatively on the environment. Impacts can be point source or diffuse; however all should be considered in performance measurement. To estimate potential environmental impacts from the use of nitrogen fertilizer, a biophysical model of dairy grazing systems, DairyMod, is used to simulate individual farming practices and determine the likely extent of leaching and run-off from each farm. Although not the only environmental impacts of farming, leaching and run-off are two variables that can be measured and combined with other marketed inputs to determine farm performance.

BIOPHYSICAL SIMULATION IN SUPPORT OF CROP PRODUCTION DECISIONS: A CASE STUDY IN THE BLACKLANDS REGION OF TEXAS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dillon,   Carl R.; Mjelde,   James W.; McCarl,   Bruce A.
Economic feasibility of Texas Blacklands corn production in relation to sorghum, wheat, and cotton is studied. Biophysical simulation generated yield data are integrated with an economic decision model using quadratic programming. Given the various scenarios analyzed, corn is economically feasible for the Blacklands. A crop mix of half corn and half cotton production is selected under risk neutrality with wheat entering if risk aversion is present. Corn and grain sorghum production are highly substitutable. Profit effects attributed to changing corn planting dates are more pronounced than profit changes resulting from altering corn population or maturity class.

BOUNTIES FOR FERTILIZERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mauldon,   Roger G.
Bounty payments on fertilizers have rapidly emerged as a major form of assistance to Australian agriculture. They have been justified as a way of reducing costs and increasing productivity, though economic theory and experience from agricultural production studies suggest that they achieve these objectives inefficiently. The bounties are directed towards making acres more productive, which should in turn make farmers more productive. It is suggested that greater economic welfare would result from tackling the problem the other way round.

Autores: Mekuria,   Mulugetta; Waddington,   Stephen R.; Siziba,   Shephard.
Smallholder farmers in southern Africa face acute food insecurity because the productive capacity of their soils has declined. These resource-poor farmers increasingly cannot afford mineral fertilizers Farmers mentioned the lack of fertilizers for their depleted soils as the most important constraint- "Empty Soils, stomachs and pockets." In response to this challenge, Soil Fert Net researchers in southern Africa have developed and promoted a range of "best-bet" soil fertility management technological (SFMT) options for farmers. This paper presents a review of financial, adoption, institutional and policy analysis undertaken by EPWG members on the use of SFMT by smallholders.

Autores: Brennan,   John P.; Godden,   David P.; Smale,   Melinda; Meng,   Erika C.H.
As part of an ACIAR-funded project on genetic diversity in wheat in Australia and China, Australian wheat breeders were surveyed to assess the importance of genetic diversity to breeders. This paper reports the findings of that survey, and identifies the key issues that concern wheat breeders. The issues addressed include the breeders’ attitude to diversity and the diversity available in their current gene pool. The sources of materials that breeders use to maintain and/or increase diversity in their programs are identified, and ways in which diversity influences breeding decisions are also examined. More importantly from the policy view point, survey responses identify changes over time in the environment in which breeders operate that affect the extent...

Autores: Chudleigh,   Peter D.
This study is an ex-post, economic assessment of two projects supported by ACIAR and concerned with the breeding and quality analysis of rapeseed in Australia and China. These projects were carried out sequentially with the first one commencing on 1 July 1986. The second one was completed on 30 June 1991. The projects were essentially an exchange of knowledge and germplasm of rape (Brassica napus) between plant breeders in Australia and China. The projects resulted in the release of varieties of rape that yielded improved seed in Australia, China and other developed and developing countries.  An economic evaluation of these projects was made in 1991 and the results published in Chudleigh (1991). Assumptions made in the 1991 analysis have now been updated....

Autores: Vandeplas,   I.; Vanlauwe,   Bernard; Merckx,   Roel; Deckers,   Jozef A.
The Tropical Soil Biology and Fertility Institute of the International Centre of Tropical Agriculture (TSBF-CIAT) introduced dual purpose soybean varieties in south-west Kenya both to improve soil fertility by nitrogen fixation and to provide a source of better food and income. Since the start of the project in 2005, the Uriri Farmer Cooperative Society was successful in spreading the seeds over the district. Nevertheless, farmers still had problems with soybean agronomy. We therefore started a Collaborative Experiment (CE) Approach in March 2006 to make soybean production more accessible to farmers. The approach consisted of four stages: 1) information sessions; 2) participatory rural appraisal; 3) collaboration in the whole process of experimentation,...

Following the dissolution of the former Soviet Union and the collapse of existing trade arrangements, the newly independent states of Central Asia were left with the task of developing their own independent market economies. The region has undergone tremendous economic and social changes including significant agricultural reform mainly targeted at privatizing large collective farms that were established during the Soviet era. These reforms include the establishment of smaller private and cooperative farms in order to improve the efficiency and equity of existing production systems. Within Uzbekistan, this move to privatize farms has, in the majority of cases, led to declining productivity and net incomes. However, there have been instances where privatized...

Bt and Ht Corn versus Conventional Pesticide and Herbicide Use. Do Environmental Impacts Differ?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nillesen,   Eleonora; Scatasta,   Sara; Wesseler,   Justus.
In this paper we empirically assess and compare the environmental impact of pesticide programs for Bt, Ht (glufosinate) and conventional corn in Europe, employing the Environmental Impact Quotient. We use field trial data from Narbons, France 2004 as well as secondary data. Our results show that management of Bt corn has a lower environmental impact than conventional corn programs. Herbicide treatment of the Ht variety also has a much lower environmental impact than that of the two conventional programs. Our empirical findings support the argument of lower environmental and health impacts with respect to pesticide use when growing Bt and Ht corn. The outcomes are relevant for environmental benefit-cost analysis of Bt and Ht corn.

BT CORN AND INSECT RESISTANCE:  AN ECONOMIC ASSESSMENT OF REFUGES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hurley,   Terrance M.; Babcock,   Bruce A.; Hellmich,   Richard L.
Genetically engineered crops offer farmers a new option for controlling pests.  The high efficacy of these pesticidal crops, combined with the potential for widespread adoption, has raised concerns that pest resistance may prematurely diminish their value.  In response to these concerns, the Environmental Protection Agency requires resistance management plans.  Current resistance management plans rely on a high-dose refuge strategy.  This analysis extends the current framework for evaluating high-dose refuge strategies to include a measure of agricultural productivity and conventional pesticide use.  The economic tradeoff relative to agricultural productivity, conventional pesticide use, and pest resistance is assessed when Bt corn is planted to control...

Bt Corn Farmer Compliance with Insect Resistance Management Requirements: Results from the 2002 Minnesota and Wisconsin Farm Polls
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Buttel,   Frederick H.; Merrill,   Jeanne; Chen,   Lucy; Goldberger,   Jessica; Hurley,   Terrance M.
The U.S. Environmental Protection Agency (EPA) reregistered Bt corn in 2001 with mandatory Insect Resistance Management (IRM) requirements in order to promote sustainable use by farmers.  Since then studies report IRM compliance rates ranging from 80 to 90 percent.  Using survey data from Minnesota and Wisconsin, we show that previous compliance rate estimates are likely too high because they do not use a comprehensive measure for compliance.  With a more comprehensive measure, we find compliance rates ranging between 60 to 75 percent.

BT COTTON IN ARGENTINA: ANALYZING ADOPTION AND FARMERS' WILLINGNESS TO PAY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Qaim,   Matin; de Janvry,   Alain.
Unlike several other countries, where Bt cotton is being rapidly adopted, in Argentina technology diffusion has been rather slow. Based on recent survey data, it is shown that the technology significantly reduces insecticide applications and increases yields; however, these advantages are curbed by the high price charged for genetically modified seeds. Using the contingent valuation method, it is shown that farmer's’ average willingness to pay for Bt cotton is less than half the actual market price. A lower price would not only increase benefits for cotton growers, but could also multiply the profits of the monopoly seed producer, thus resulting in a Pareto improvement. Implications of the sub-optimal pricing strategy are discussed.

Buyer Market Power and Vertically Differentiated Retailers
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wang,   Shinn-Shyr; Rojas,   Christian; Lavoie,   Nathalie.
We consider a model of vertical competition where downstream firms (retailers) purchase an upstream input from a monopolist and are able to differentiate from each other in terms of quality. Our primary focus is to study the effects of introducing a large retailer, such as a Wal-Mart Supercenter, that is able to lower wholesale prices (i.e. buyer market power). We obtain two main results. First, the store with no buyer market power responds to the presence of the large retailer by increasing its quality, a finding that is consistent with recent efforts by traditional retailers to enhance shoppers’ buying experience (i.e. quality).

BUYER PREFERENCES FOR DURUM WHEAT: A STATED PREFERENCE APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lee,   Mimi; Lerohl,   Mel L.; Unterschultz,   James R.
The central issue addressed in this paper is the attributes preferred by a sample of buyers of durum wheat grown in Canada.  Primary emphasis is the value placed on certain visual and nonvisual attributes by US buyers of durum wheat.  In addition, a source variable in the analysis is used to test preferences of US buyers for US-source compared to Canadian-source durum.  The latter is a method to test whether durum millers in the US believe that Canadian durum is a superior product, a view widely-held in the Canadian grain trade.  Results indicate that higher bushel weight has a positive effect on purchase probability, and appears to be more important to buyers' purchasing decision than protein content, amylase content, or the choice between no. 1 and no. 2...

Búzatermelés – olcsón vagy jól?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fodor-Nemeth,   Barbara.
Az utóbbi időben a mezőgazdasági termelők jó része elfordult az intenzív termeléstől, és költségkímélő módon kezdett gazdálkodni. Nem a körülményekhez képest legnagyobb termés betakarítása a cél, hanem a lehető legnagyobb profi t. Az elmúlt két év eredményeit vizsgálva kiderült, hogy a profi t mindenképpen nőtt a költségcsökkentéssel, ugyanakkor ez a szemlélet és gyakorlat hosszú távon jelentős agronómiai problémákat okozhat.   ----------------------------------------  Recently a sizeable portion of agricultural producers have abandoned intensive production in favour of low-cost farming. Their goal is to make the most profit rather than to achieve the largest harvest possible under the circumstances. We set out to explore the economic consequences of this...

California Strawberry Production and Methyl Bromide
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Baker,   Gregory A.
California strawberry growers were faced with the possibility of losing one of their most important chemicals, methyl bromide. Methyl bromide was believed to be involved in the depletion of the ozone layer and 162 countries had signed the Montreal Protocol, which would lead to an eventual ban of the chemical. The US EPA had scheduled the complete phaseout of methyl bromide by 2001. The case is ideal for teaching the application of stakeholder analysis to both undergraduate and graduate classes.

CAN AGRICULTURAL PRODUCTION IN THE MARGINAL LANDS CONTRIBUTE TO IMPROVING FOOD SECURITY IN THE SAHELIAN AFRICAN COUNTRIES: AN EVIDENCE FROM THE BAS-FOND RICE PRODUCTION IN MALI
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dimithe,   Georges; Bernsten,   Richard H.; Staatz,   John M.; Sanogo,   Ousmane; Coulibaly,   B.S.; Simpara,   M.
To improve national food security, successive Mali governments have always focused on expanding and intensifying production in the government-managed irrigation schemes (Office du Niger), which account for about 50% of domestic rice production.  Because the cost of expanding and  rehabilitating those schemes is high, the government is looking for complementary cost-effective ways to achieve this goal.  The government could increase domestic rice supply by investing in improving the farmer-managed inland valley swamps.  Although the government has paid little attention to those marginal lands, farmers have been growing rice in these areas using traditional technologies.  This paper used data from a survey of 334 bas-fond farmers and secondary data to...

Can Bt Technology Reduce Poverty Among African Cotton Growers?  An Ex Ante Analysis of the Private and Social Profitability of Bt Cotton Seed in Mozambique.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pitoro,   Raul; Walker,   Thomas S.; Tschirley,   David L.; Swinton,   Scott M.; Boughton,   Duncan; de Marrule,   Higino Francisco.
This paper presents an ex ante analysis of the private and social profitability of the introduction of Bt cotton for a major cotton producing area of northern Mozambique.   Cotton is especially relevant to rural poverty reduction because smallholders often have few alternative cash earning activities, and yields are among the lowest in Africa.  Multivariate regression is used to quantify the relationship between pest control and yield loss at farm level as a basis for estimating the expected yield gain from the introduction of Bt cotton.  Partial budget analysis of technical packages with and without Bt cotton seed reveals a strong divergence between private (negative) and social (positive) profitability.  The Mozambique case indicates that effective...

Can Conventional Crop Producers Also Benefit From Bt Technology?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dun,   Zhe; Mitchell,   Paul D.
Transgenic plants producing insecticidal protein derived from Bacillus thuringiensis (Bt) have been widely adopted since their commercial introduction in 1996.  In 2009, 25 countries planted 134 million ha of transgenic crops. The widespread adoption of such plants has reduced use of conventional insecticides while attaining yield gains, thus providing economic, environmental and human health benefits. Because of Bt crops’ high pest control efficacy, there is concern that pests will develop resistance to Bt toxins so that Bt crops are less or no longer effective. To delay the evolution of resistance, the U.S. Environmental Protection Agency (EPA) currently requires Bt crop growers to also plant non-Bt (conventional) crops on a minimum percentage of their...

Autores: Egbendewe-Mondzozo,   Aklesso; Swinton,   Scott M.; Bals,   Bryan D.; Dale,   Bruce E.
This paper compares environmental and profitability outcomes for a centralized biorefinery for cellulosic ethanol that does all processing versus a biorefinery linked to a decentralized array of local depots that pretreat biomass into concentrated briquettes.  The analysis uses a spatial bioeconomic model that maximizes predicted profit from crop and energy products, subject to the requirement that the biorefinery must be operated at full capacity.  The model draws upon biophysical crop input-output coefficients simulated with the EPIC model, as well as input and output prices, spatial transportation costs, ethanol yields from biomass, and biorefinery capital and operational costs. The model was applied to 82 cropping systems simulated across 37...

Analysis of a survey of the 1998-99 and 1999-2000 seasons for the same 100 smallholders in the Makhathini Flats region of KwaZulu-Natal shows that Bt cotton has performed better than other varieties.  Having two years of data for the same farmers allows innate efficiency differences, due to factors such as farm size, to be separated from the effects of the new technology, which is not normally possible. Farmers who adopted Bt cotton in 1999-2000 benefited according to all the measures used.  Higher yields and lower chemical costs outweighed higher seed costs, giving higher gross margins. These measures showed negative benefits in 1998-99, which conflicts with continued adoption, but stochastic efficiency frontier estimation, which takes account of the...

Can virtual water 'trade' reduce water scarcity in semi-arid countries? The case of Spain
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Garrido,   Alberto; Novo,   Paula; Rodriguez Casado,   Roberto; Varela-Ortega,   Consuelo.
Agricultural trade is by far the largest vehicle to ‘move’ water virtually around the world. Observing that most countries import and export water embedded in the exchanged products, the objective of this study is to assess the virtual water ‘trade’ in Spain for the period 1997-2006. We differentiate between the green and blue components of virtual water from a hydrological and economic perspective. The combination of spatial and time dimensions offers a unique empirical setting to determine whether virtual water ‘trade’ can contribute to reduce water scarcity. The study reveals that Spain is a net ‘importer’ of virtual water. By far the largest virtual water ‘imports’ are linked to cereals and animal feed products whilst the virtual water ‘exports’ are...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Park,   Joon J.; Wilson,   William W.; Johnson,   D. Demcey.
The Canadian grain handling and transportation system has undergone substantial change in recent years, particularly since the elimination of rail subsidies in 1995. Competitive pressures and branch line abandonment have forced many primary elevators to close, while scores of new high-throughput elevators have been constructed across the Prairies. Rationalization of the grain handling system and proposals for further deregulation of rail transportation are driven by the need to improve system efficiency. Policy recommendations of the Estey Report (notably, the elimination of rail rate caps, and 'port buying' by the Canadian Wheat Board) would have important consequences for the grain trade and are contentious issues within Canada. Changes in grain...

The objective of this paper is to characterize the production of roses at the region of Barbacena and to identify its transaction attributes, that is, asset specificity, transaction frequency, and uncertainty. The research is based on the theoretical framework of the New Institutions Economy which allows the use of qualitative methods in order to understand in depth the study object. The results have shown that rose producers in the region of Barbacena seek to demand the requirements of their customers, but they perceive the need of improvement in the productive chain through associations and contractual relations, informal ones included, among the agents involved in the agribusiness of roses.

Carbon sequestration through the planting of multi-annual energy crops: A dynamic and spatial assessment
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: de Cara,   Stephane; Rozakis,   Stelios.
In this study, we examine the spatial and dynamic implications of policies aimed at increasing carbon sequestration in agricultural soils. We consider incentive mechanisms designed to encourage the planting of energy multi-annual crops that allow higher carbon sequestration rates for a longer period of time. By using a dynamic micro-economic model, we simulate the sequence of crop plantings over a given time horizon and investigate different payment mechanisms (per-ton or per-hectare). We discuss their implications in terms of regulation policy and efficiency. This model is then applied to the Central Plains of Thessaly, Greece, to assess the marginal costs of carbon sequestration and the optimal timing of switching to multi-annual energy crops. To do so,...

This paper is based on the premise that if CARICOM’s agricultural sector in general, and more specifically the export sub-sector, is to thrive in the rapidly changing trade environment there has to be a continuous systematic assessment of market opportunities and competitiveness status.  Such an assessment however, requires a clear understanding of the multifaceted concept of competitiveness and its major determinants.  This paper seeks to contribute to the regional discussion of competitiveness, through the exploration of the theoretical and empirical dimensions of the concept within the context of CARICOM’s export of specialty crops to the United States.  The paper uses a methodology heavily based on the Module to Analyze the Growth of International...

Case Studies on the Use of Crop Insurance in Managing Risk
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gloy,   Brent A.; Staehr,   A. Edward.
Managing the risk associated with farming is challenging. Fortunately, farmers have a variety of risk management tools at their disposal. This series of case studies examines how crop insurance can be used to manage some of the risks faced by farmers. The examples illustrate how crop insurance purchases would impact the returns generated to a farming enterprise. While the examples cover a variety of commodities and insurance products, they do not consider every possible risk that might arise. Likewise, they do not consider all of the possible financial situations that might be experienced by a farmer. Instead, they focus on highlighting how crop insurance impacts the profitability of the farm. Companion spreadsheets are available for all of the examples so...

Autores: Kelly,   Valerie A.; Diagana,   Bocar N.; Reardon,   Thomas; Gaye,   Matar; Crawford,   Eric W.
Senegal has experienced a number of spurts in agricultural production and productivity growth since independence, yet average trends from 1960 through 1993 have been either stagnant (in terms of aggregate production and yields), or negative (in terms of real value of production). Although use of animal traction is ubiquitous, current crop production in the Peanut Basin must be characterized as low external input farming. Farmers are unanimous in their belief that the most important constraint to improving agricultural output is their inability to obtain desired quantities of peanut seed. Inadequate seed has led to lower peanut income and a diminished capacity to purchase productivity-enhancing inputs: aging animal traction equipment is not being replaced,...

CASH MARKETING STYLES AND PERFORMANCE PERSISTENCE OF WHEAT PRODUCERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cunningham,   Lewis T., III; Brorsen,   B. Wade; Anderson,   Kim B.
Years of research have been dedicated to determining the best time for producers to sell their commodities. Researchers have developed basis models, market efficiency tests, hedging/risk models, price forecasting models, and many other models in an attempt to help producers. There is a vast amount of material on how economists believe that a rational producer should act and react in the market place. However, there is little research on how producers actually sell commodities. This paper first measures the extent to which producers display an active or mechanical marketing style using individual farmer sales. Next, tests of performance persistence are conducted to determine if there is any advantage to an active marketing style. The results show that...

Cash Wheat Marketing: Strategies for Real People
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brorsen,   B. Wade; Anderson,   Kim B.
A new paradigm is needed in extension marketing programs. Attempts to help producers time the market, either through cask sales or futures trading, appear to be of little benefit. Marketing extension programs need to place less emphasis on outlook and futures trading and more emphasis on simple marketing strategies that people really use. An empirical example of strategies for Oklahoma wheat producers shows selling cash wheat at harvest and participating in government programs as the preferred marketing strategy.  Implications for extension programs in other states are that extension programs can help producers decide whether to store their grain and whether to participate in farm programs.

Cassava Commercialization in Malawi
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kambewa,   Emma.
Malawi continues to rely on maize for household food security. Policies to enhance food security continue to target maize production. Traditionally production and use of cassava was localized in lakeshore areas until the past two decades when maize production was increasingly affected by rainfall variability. Cassava as an alternate food crop has rapidly gained popularity and commercialization of the cassava sector is steadily taking off. Policy and institutional support to diversify the food security basket and promote the diversified applications of cassava in non-food sector has propelled cassava production in nontraditional growing areas. Production has more than quadrupled over the last decade with production of sweet cassava rapidly expanding in...

CASSAVA SUPPLY RESPONSE IN MINAS GERAIS STATE, BRAZIL:  AN EMPIRICAL EVALUATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rodrigues,   Lecio Maria.
When the Portuguese and Spanish navigators landed on the American continent in the 15th century, they found cassava being grown by Indians and used to prepare food and alcoholic drinks.  For this reason, cassava can be considered a native American plant which has spread to other regions of the tropics.  Cassava refers to any of several plants which are grown widely in many areas of the tropics for their fresh, starchy, edible root stocks.  It is known as cassava in English speaking regions, as manioc in French speaking areas, as tapioca in English speaking parts of Southeast Asia, as mandioca in Brazil, and as yuca in Spanish speaking regions of South America.  As one of the largest countries in the world, and with the necessity for much greater emphasis...

Catastrophic Drought Insurance based on the Remotely Sensed Normalized Difference Vegetation Index for Smallholder Farmers in Zimbabwe
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Makaudze,   Ephias M.; Miranda,   Mario J.
Index insurance, which indemnifies agricultural producers based on an objectively observable variable that is highly correlated with production losses but which cannot be influenced by the producer, can provide adequate protection against catastrophic droughts without suffering from the moral hazard and adverse selection problems that typically cause conventional agricultural insurance programs to fail. Using historical maize and cotton yield data from nine districts in Zimbabwe, we find that catastrophic drought insurance contracts based on the Normalized Difference Vegetation Index (NDVI) can be constructed whose indemnities exhibit higher correlations with yield losses compared to the conventional rainfall index. In addition the NDVI contracts can be...

CAUSES OF INSTABILITY IN CEREAL PRODUCTION IN ETHIOPIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Alemu,   Zerihun Gudeta.
In Ethiopia, average cereal production between the period 1990 and 2000 did not change significantly compared to the period between 1974 and 1990. However, cereal production between the period 1990 and 2000 was characterized by significant instability. This study reviews literature on factors with potential impact on instability in cereal production in Ethiopia and applies descriptive and variance decomposition procedures to determine the sources of increased instability in cereal production. It was found that production instability was caused more by increased yield instability than instability in an area. Yield instability could be the result of changes in technology, changes in policy and changes in weather conditions. It was concluded by this study...

This paper synthesizes the evidence on cereal crop productivity in developing countries over the past 30 years and looks at future prospects for productivity growth. For more than three decades we have witnessed the phenomenal growth of cereal crop productivity in the developing world. Termed the Green Revolution, the initial phase of this growth resulted from an increase in land productivity and occurred in areas of growing land scarcity and/or areas with high land values. Significant investments in research and infrastructure development, especially irrigation, were the strategic components of this increased productivity. In the post-Green Revolution period, particularly in Asia, productivity growth has been sustained through increased input use and,...

Teff, wheat and rice are becoming important market oriented crops in Ethiopia. This study aims at analyzing the market participation of farm households, market actors, market channels and determinants of household market participation for these crops. Results are based on analysis of data collected from community and household surveys in three districts in three regional states of the country in 2005. Analysis of descriptive information and econometric analysis are used. About 65 - 77% of households produce these market oriented commodities, on about 27 – 44% of the total cultivated area. About 47 – 60% of the produce of these market oriented commodities is sold.  The important market places for producers of these commodities are the district town markets...

Managing food price instability is a long standing policy challenge, which, with mixed experiences of agricultural price policy reforms, has re-emerged as a contemporary policy issue. This is particularly true for Ethiopia, where managing food price stability continues to be a formidable policy challenge. The objective of this paper is to examine the underlying causes of cereal price instabilities and to assess the policy options to manage them. It undertakes three tasks: (a) analyzes the sources and degree of cereal price instability, (b) discusses the viability of various policy options, and (c) critically reviews the country’s past, ongoing, and emerging policies for food price stabilization. The results show that the determinants of price...

This paper presents a methodology to evaluate the impact of different policy scenarios using a farmer's utility function. The analysis shows the impact on farmers and on the environment. The case study is a community of irrigated farms (Bajo Carrión) in Northwestern Spain. The results obtained show how Agenda 2000 has little impact on farm crop distribution, gross margins, employment and environment (use of fertilizers and water). The most radical scenario (a 15 per cent COP price cut and no area payments) produces a 37.3 per cent reduction in farm gross margin, and an increase in fertilizer use of 6 per cent.

This note demonstrates that a certain class of stochastic problems for determination of optimal fertilizer application rates in the presence of fertilizer carry-over can be simplified to static, certainly equivalent problems.  Conditions required for certainty equivalence to hold are:  (1) fertilizer carry-over is agronomically equivalent to applied fertilizer; and (2) some addition of fertilizer is optimal in every decision period.

CERTIFICATION AND SUPPLY RESPONSE IN THE ORGANIC LETTUCE MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lohr,   Luanne; Park,   Timothy A.
The impact of supply relationships and certification programs on the organic lettuce market is examined using an integrated partial adjustment and asymmetric supply response model. Costs associated with organic certification, production, and marketing have not restricted producers’' abilities to respond to price signals. Organic growers allocate output between certified and noncertified markets in response to changing price premiums. Estimates of short-run supply elasticities indicate that organic lettuce growers are more responsive to price changes than producers of nonorganic lettuce. Long-run elasticity has increased since 1988, a change that coincides with the market entry of larger producers.

The current marketing of agricultural products in general, and of bananas in particular, poses special problems for Eritrean farmers. Poor climatic conditions coupled with crude and inefficient agricultural technologies render agricultural output sub-optimal. The major production problems include shortage of capital and scarcity of land; shortage of farming materials; spoilage of bananas during harvesting due to inappropriate harvesting techniques and facilities and lack of technical know how. In addition, the main marketing problems comprise transport problems to stores; general storage problems; lack of information and spoilage during transport.  Taking the above into account it should be noted that current trends towards the increased globalization of...

Changes in cereal land use and production level in the European Union during the period 1999-2009, focusing on New Member States

The decrease in the area of arable land has further continued in the European Union (EU) since the Millennium. Sustainable development is partially based on the sustainable use of natural resources, which is based on the limitation of land use and on the introduction of different incentives. Previous direct subsidies resulted in increased production. The reform of the Common Agricultural Policy (CAP) has aimed to stop the increase in production, possibly even to decrease production. The objective of this research is to show whether such an effect on land use and on the change of production structure in the EU can be observed. Analyses have shown that agricultural and arable areas have further decreased within land use since the Millennium, continuing the...

By applying precision nutrition the yield heterogeneity owing to the different features of soil spots can be taken into consideration. The planned and sprayed fertilizer adjusted to the expected yield rendered to soil spots can reduce the negative effects of artificial chemicals on soil and environment. The aim of this paper is to examine how the quantity and the cost of fertilizer (material and operational) will change on spot level on a certain plot during a five-year period, considering crop rotation, too. The following crops are in the rotation: winter wheat, corn and sunflower. Precision nutrition can be used in all the cultures mentioned above.

Farming systems research for wet-season non-rice upland crops in Cambodia is being conducted with the overall aim of poverty reduction and food security for farmers in the Provinces of Battambang and Kampong Cham. Some of these cash crops exhibit low and variable incomes, especially when grown in the early wet season. Cambodian farmers may borrow money to buy crop inputs and often sell their produce to companies and traders from neighbouring countries, hence they are price takers. Some new crop technologies are evaluated which relate to soil and crop fertility management interacting with climatic factors. The DSSAT crop simulation model is used to predict outcomes from alternative management strategies. Bio-economic analyses are conducted to assess the...

Autores: Walshe,   Kim.
This paper evaluates changes in the fisheries regulation environment in New Zealand’s marine fisheries from 1970 to 2003. The quota management system was heralded as the introduction of a market based reform, with a move away from input controls to output controls. The QMS impacted primarily on the commercial sector but also the recreational sector. It was hypothesized (by policy advisors and policy makers) that the QMS would lead to less government intervention and less regulation for the commercial sector. The paper presents findings that suggest the expectations of policy makers may have been misplaced.

An interregional competition model of the U.S. apple industry is constructed.  This model includes the consumer products of fresh apples, applesauce and apple juice.  The validation of the model showed that it did a good job of estimating consumer's quantity demanded and prices and a reasonable job of estimating utilization.  This model was used to study the effects of transportation cost changes on the industry in the short- and intermediate run.  The total production and consumption levels changed by moderate amounts with changing transport costs while the utilization of a region's crop was quite sensitive to such changes.

Changes in Yield Stability: Wheat and Maize in Developing Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gollin,   Douglas.
This study asks whether the diffusion of modern varieties has affected the yield stability of wheat and maize production in developing countries between 1960 and 2004. The data suggest strongly that, over the past forty-plus years, there has been a striking decline in the relative variability of grain yields in wheat and (to a lesser extent) maize. The declines are strongest when measured as the standard deviation of yield divided by the mean, but there have also been declines in other measures of variability, such as the percentage deviation from trend. Declines in yield variability do not appear to be driven by increases in intensification (e.g., irrigation), nor do they appear to extend to crops, such as oilseeds, in which there has been little...

Autores: Longmire,   James L.; Moldashev,   Altynbeck.
Economic incentives in Kazakhstan have been radically reshaped since the Soviet era ended in 1991. In the first phase of transition, the economy and agricultural sectors declined by 40-50%. Overall economic growth refused in 1996, and agriculture is likely to enter a recovery phase soon. The economy of Kazakhstan is undergoing rapid structural change, and agriculture is experiencing strong inter-sectoral competition. The change to market-oriented and commercially-driven agriculture has altered fundamentally the incentives faced by Kazakhstan's wheat farmers. They have reduced use of inputs sharply because of the need to pay market prices for fertilizer, fuel, and other inputs, while severely curtailing investment in machinery and their farms generally....

The rise of supermarkets, together with large-scale food manufacturers, has deeply transformed agri-food markets in many countries. This expansion has been evident in South Africa as well. Increasing attention has been and is being paid to the growth of supermarkets in countries outside of North America and Europe. Numerous studies have been carried out in developing countries, including South Africa. However, these studies, while identifying the growth of supermarkets and the changes in supply chains, notably downstream, that have been caused by this growth, have made relatively little progress in documenting the impacts at producer level and in identifying issues that need to be addressed. There is a special need for studies on how farmers and supporting...

Changing Incentives to Sow Cotton for African Farmers: Evidence from the Burkina Faso Reform
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kaminski,   Jonathan.
Over the last 10 years, Burkina Faso has experienced a reform of its cotton sector, and is now the largest African cotton producer and exporter. The cotton ”boom” consisted of a rapid expansion of cotton areas through the growth of land shares allocated to cotton (and new producers), together with an overall increase in total cultivated land. In this paper, we present an empirical framework to determine the contribution of total farmland changes in the increase of land dedicated to cotton, where both processes are represented by ordered endogenous variables. We then analyze data that we collected in rural Burkina Faso in March 2006 within this framework. From measurable indicators of farmer behavior and variables that measure farmer statements for the...

In 1995, the Agreement on Textiles and Clothing (ATC) provided for the calculated liberalization of the textiles and apparel sectors over a 10-year period ending in 2005, except for some safeguard measures ending on December 31,    2008.  These safeguard measures allowed for import restrictions by the U.S. on certain categories of cotton apparel from China.  Using a 57-equation, annual econometric, price equilibrium simulation model of the U.S. cotton and cotton apparel markets, results point to lower cotton apparel prices in the U.S. by as much as $ 0.25 per kilogram while cotton prices decline by less than $ 0.01 per kilogram once these safeguards expire.  In the baseline scenario, quotas are removed in 2009-2015 except for the safeguards. In the...

Changing Patterns of Wheat Production and Consumption in China: Trade Implications
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tian,   Wei-Ming; Zhou,   Zhang-Yue; Cao,   Yi-Yang.
In the 1980s and early 1990s, wheat imports accounted for about four-fifths of China's import of cereals, and imported wheat accounts for about 30 percent of wheat supply. As a result of the many recent developments in Chinese government’s policy on wheat production and marketing as well as China’s WTO accession negotiations, how the Chinese wheat market will evolve presents an interesting and important area for policy makers and major wheat trading companies both within and outside China. In this paper, we highlight recent changes in China's wheat production and consumption patterns and marketing arrangements. We then, by taking into account of likely government policy scenarios, analyse implications of such changes on wheat market development in China...

Three representative Tennessee tobacco farms are used to estimate farm-level impacts of (1) program continuation with further quota cuts, and (2) program elimination in 2000.  Results indicate that program elimination has more potential to reduce farm income and that larger and more diversified farms are less affected in both scenarios.

As part of a review of changing patterns of variability in cereal production around the world, the situation in Australia is examined both by major cereal crops and by State in which they are grown. The Australian results are generally consistent with those found in parts of both the industrial and developing world. There has been a tendency for production and especially yields to become both somewhat more variable as assessed by the dimension-free measure, the coefficient of variation, and more covariate between producing regions. The two post-World War II sub-periods examined are dominated, respectively, by tall (traditional) and short (modern) cultivars suggesting that there may be a causal link between cultivar used and relative yield variability.

This study aims to characterise the evolution of vineyard production, to measure the levels of technical efficiency, and to relate these with farmers and farms attributes. The sample used is composed of a panel of vineyard farms, for the period 2000-2005, belonging to Portuguese Alentejo region. The methodology used to estimate technical efficiency, was the stochastic production frontier. The results showed that there are room to improve the levels of technical efficiency in input use and that efficiency is variant with time. It was observed that technical efficiency increases with economic size and net farm income, as well as with family entrepreneurship.

Characteristics and Production Costs of U.S. Corn Farms, 2001
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Foreman,   Linda F.
Corn production costs per bushel vary considerably among U.S. producers, depending on yields, farm location, tillage practices, irrigation, previous field usage, enterprise size, and weather. In 2001, the operating and ownership costs per bushel for corn ranged from an average of $1.08 for the 25 percent of U.S. producers with the lowest costs to an average of $2.98 for the 25 percent with the highest costs. Heartland corn producers had the lowest costs per bushel on average. Corn producers with small corn enterprises had the highest costs due to their lower-than-average corn yields. Operators of part-time and low-sales corn farms have higher production costs per bushel than operators of farms with higher sales. In 2001, 59 percent of corn producers earned...

Organic milk production has been one of the fastest growing segments of organic agriculture in the United States in recent years. Despite the growing number of organic dairy operations, the characteristics of organic dairy operations and the relative costs of organic and conventional milk production have been difficult to analyze. This study, using 2005 ARMS data for U.S. dairy operations, which include a targeted sample of organic milk producers, examines the structure, costs, and challenges of organic milk production. The analysis addresses economies of size, regional differences, and pasture use in organic milk production and compares organic and conventional milk production costs. The findings suggest that economic forces have made organic operations...

Charging for irrigation water:  The issues and options, with a case study from Iran
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Perry,   Christopher J.
Inadequate funding for maintenance of irrigation works and emerging shortages of water are prevalent. The use of water charges to generate resources for maintenance and to reduce demand is widely advocated. Examples from other utilities, and from the domestic/industrial sectors of water supply suggest the approach could be effective. In developing countries, the facilities required for measured and controlled delivery of irrigation are rarely in place, and would require a massive investment in physical, legal and administrative infrastructure. To be effective in curtailing demand, the marginal price of water must be significant. The price levels required to cover operation and maintenance (O&amp;M) costs are too low to have a substantial impact on demand,...

Charging for the use of plant varieties
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kingwell,   Ross S.
Private and many publicly funded plant breeding organisations charge farmers for use of varieties they develop. This article compares four alternative charging mechanisms and outlines responses to these alternatives by farmers and plant breeders. Risk‐averse farmers and breeders are shown to have opposite preferences for charging mechanisms. Results suggest profit‐based or royalties are preferred by farmers whereas breeders prefer area or tonnage‐based royalties. Risk‐sharing arrangements between both parties could lead to an overall preference for profit‐based or royalties. However, this finding is subject to important caveats and practical limitations.

CHEMICAL AND FERTILIZER APPLICATIONS IN RESPONSE TO CROP INSURANCE: EVIDENCE FROM CENSUS MICRO DATA

Autores: Roberts,   Michael J.; O'Donoghue,   Erik J.; Key,   Nigel D.
This paper presents preliminary evidence on the effect of crop insurance on fertilizer and chemical inputs in agriculture.  Our estimates are based on two sources of identification that emerge from a policy change concerning insurance subsidies that approximately doubled total premiums and the share of acres insured.  First, we compare per-acre applications on these inputs from the same farms before and after the policy change.  Second, we compare farm-level changes in input applications to differential changes in coverage growth induced by the policy change.  We are able to make this second comparison because farms in some regions were more heavily insured than others before the policy change so they were not required to increase coverage in order to...

Autores: Fang,   Cheng; Babcock,   Bruce A.
In this paper we provide an analysis of China's cotton policy and develop a framework to quantify the impact of both China's World Trade Organization (WTO) accession and Bt (Bacillus thuringiensis) cotton adoption on Chinese and U.S. cotton sectors. We use a Chinese cotton sector model consisting of supply, demand, price linkages, and textiles output equations. A two-stage framework model provides gross cropping area and total area for cotton and major substitute crops from nine cotton-producing regions in China. Cotton demand, total fiber demand, and cotton share are estimated for each end user. The estimated parameters from the Chinese model are then used with the Food and Agricultural Policy Research Institute (FAPRI) modeling system to simulate various...

The impact of China's new rural income support policy and recent price trends on grain production and rural income inequality is assessed for two villages with different degrees of market access in Northeast Jiangxi Province. Two village-level general equilibrium models are used to analyze household decision making and interactions between households within these villages. Parameter estimation and model calibration is based on data collected during an extensive survey held in these villages in the year 2000. The household classification used in these models allows us to draw conclusions that are relevant for many other villages and regions in China. Simulation results show that the income support policy does not reach its goal of promoting grain...

Irrigation occupies a central position in China’s crop production. However, due to low per capita water resources, much worse, unevenly distributed over regions and time and the rapid increase of water diversions to non-irrigation sectors, irrigation water shortages have become a very serious problem. Without the adoption of effective measures this problem may even threaten China’s food security. Currently, irrigation efficiency is very low in general, irrigation water prices cannot fully recover water supply costs, and irrigation facilities are aging due to the lack of funding for O&amp;M (operation &amp; maintenance). Since water prices are regulated by the government, and not determined by the market, water prices did not work effectively in water...

Autores: Ferrer,   Stuart R.D.; Nieuwoudt,   W. Lieb.
A Principal components analysis and multiple regression techniques are used to analyse heterogeneity in 53 KwaZulu-Natal sugarcane farmers soil conservation decisions. Minimum tillage and construction of water carrying terraces are the most common methods used, whereas trash mulching is least commonly practised. Results indicate that farmers' demands for soil conservation, their demands for other attributes of soil conservation practices and interactions between practices are important to explaining their choices. Intra-farm variation in use of soil conservation methods is small relative to inter-farm variation. Education programmes, provision of information, and improving farmers' technical soil conservation skills have implications for aggregate soil...

An analysis of socio-economic driving forces in crop protection is proposed to improve the implementation of sustainable strategies. The analysis includes: (1) a classification of agricultural systems based on pesticide use intensity and safety, (2) an evaluation of the profitability of farming systems and identification of socio-economic factors that influence pesticide use and (3) formulation of policy recommendations. We find that for cereals and for fruit trees alike, crop yields are much higher for agricultural systems with high doses of pesticides. The safety of applied pesticides does not affect crop protection costs significantly. For cropping systems characterised by low-intensity in pesticide use, the application of safer products has a positive...

This study examines the impact of climate on yield for seven major crops in Taiwan based on a pooled panel data of 15 counties over the period 1977-1996.  Unit-root tests and maximum likelihood methods are explored to obtain reliable estimates. Results suggest that climate has diversified impacts on crop yields and their variability.  A simple crop insurance model by Ahsan, Ali, and Kurian (1982) is shown how crop yield distribution can be the base to calculate the premium and indemnity.

Autores: Li,   Zhuang; Mount,   Timothy D.; Kaiser,   Harry M.
The analysis is based on an integrated climatic, agronomic and economic model of grain production in the midwestern region of the U.S. The model represents a typical farm and the objective is to select an optimum combination of cultivars for four crops (maize, soybean, wheat and sorghum) conditionally on climate, soil characteristics and the prices of the four crops. The first part of the analysis uses a complete two-way factorial design to estimate the effects of five climatic and agronomic variables and the four prices on yields, total production and net return. With this design, variability can be allocated uniquely to individual explanatory variables. As expected, prices have little effect on yields. For total production and net return, temperature and...

Climate Change Impact on Rice Yield and Production Risk
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kim,   Man-Keun; Pang,   Arwin.
The relationship among rice yield and weather variables in Korea is explored using a stochastic production function. The results reveal that average rice yield is positively related to temperature and negatively associated with precipitation. Both temperature and precipitation, which are risk-increasing inputs, are positively related to rice yield variability. The widened yield variability can be transferred to the fluctuation of rice production and rice price instability. Larger market risk is expected in the future since both temperature and precipitation are anticipated to increase. An evaluation of climate change impact on rice yield variability reveals that it may increase by up to 10%~20%. Reducing yield variability and managing market risk would be...

Climate Change is expected to improve crop production conditions significantly in northern Europe. In some studies a significant increase in agricultural production is expected in northern Europe while drought is becoming gradually more severe in Southern Europe and France due to climate change. Our analysis provides one of the first steps in evaluating the possible scale of changes in agricultural production and use of farm land in Finland, so far one of the least favoured agricultural areas in Europe.   Drought in early summer and low temperature sum during growing period are currently the main growth limiting factors in Finland. Even though the early part of the growing period is likely to be dry also in the future, both mean and variance of crop yields...

Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kim,   Ungtae; Kaluarachchi,   Jagath J.; Smakhtin,   Vladimir U.
The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

CLIMATE CHANGE IMPACTS ON US AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Beach,   Robert H.; Thomson,   Allison M.; McCarl,   Bruce A.
There is general consensus in the scientific literature that human-induced climate change has taken place and will continue to do so over the next century. The Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change concludes with “very high confidence” that anthropogenic activities such as fossil fuel burning and deforestation have affected the global climate. The AR4 also indicates that global average temperatures are expected to increase by another 1.1°C to 5.4°C by 2100, depending on the increase in atmospheric concentrations of greenhouse gases that takes place during this time. Increasing atmospheric carbon dioxide levels, temperature increases, altered precipitation patterns and other factors influenced by climate have...

Climate Change, Risk and Grain Production in China
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Holst,   Rainer; Yu,   Xiaohua; Grun,   Carola.
This paper  employs  the production function-based method proposed by  Just and Pope  (1978, 1979) to explicitly analyze production risk in the context of Chinese grain farming  and climate change, and  test for a potential endogeneity of climate factors in Chinese  grain production.  Our results indicate that China might, at least in the short run, become a net beneficiary  of climate change.  In particular, we find that increases in annual average temperature  increase mean output at the margin and at the same time lead to a reduction of production  risk.  Further  calculations suggest that a 1 °C increase in annual average temperature  would entail an economic benefit of $1.1 billion due to the increasing mean output.  Furthermore,  a Hausman test...

Climate's Long-term Impact on New Zealand Infrastructure (CLINZI) - A Case Study of Hamilton City, New Zealand
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jollands,   Nigel; Ruth,   Matthias; Bernier,   C.; Golubiewski,   N.
Infrastructure systems and services (ISS) are vulnerable to changes in climate.  This paper reports on a study of the impact of gradual climate changes on ISS in Hamilton City, New Zealand.  This study is unique in that it is the first of its kind to be applied to New Zealand ISS.  This study also considers a broader range of ISS than most other climate change studies recently conducted.   Using historical climate data and four climate change scenarios, we modelled the impact of climate change on water supply and quality, transport, energy demand, public health and air quality.  Our analysis reveals that many of Hamilton City's infrastructure sectors demonstrated greater responsiveness to population changes than changes in gradual climate change. Any...

COCOA PRODUCTION PROSPECT IN TOGO
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Assiongbon,   Ekoue K.
Cocoa has made an important contribution to economic development in Togo.  Until recently, virtually all of Togo's exports were agriculture, mainly:  cocoa and coffee.  In 1961, phosphate exports began, and by 1965 became the leading export commodity.  Even after the discovery and production of phosphate minerals, agriculture exports, however, continue to provide more than 30 percent of all foreign exchange and to employ about 75 percent of the active population.  Cocoa and coffee represent 70 percent of agricultural exports and cocoa alone provided an average of 27 percent of recorded export earnings between 1966 and 1975.  Since 1965, the agriculture sector has been accorded top priority in the national development plan.  However, this proclamation has...

Autores: Basu,   Jyotish Prakash.
The paper attempts to examine the market integration with the help of cointegration test on the prices of potato of Hooghly district in West Bengal. The analysis has been made at two levels, namely at the level of wholesale markets and at the retail markets. The cointegration test by Johansen and Jeselius (1990) applied to weekly prices of three important potato markets in Hooghly district suggest that the markets are integrated. Our results revealed that price signals and information are transmitted smoothly across the markets. These results have important policy implications. In a situation when potato markets are spatially integrated the government may think of reducing or even withdrawing its efforts to influence the price in the market. The finding of...

This project explored the possible role of collective action among small-scale farmers in managing and maintaining genetic resources in a center of crop diversity. It focused on the local institutions that ensure the supply of seed of diverse maize landraces to small-scale farmers in the Central Valleys of Oaxaca, Mexico. The key hypothesis was that the medium-to-long-term supply of a diverse set of varieties to any individual smallscale maize farmer depends on an agreement among a group of farmers to manage and supply the seed of these landraces to each other, if the need arises, and that this constitutes a form of collective action. Six communities were studied, three of them indepth. Methodologies used included in-depth semi-structured interviews with...

Collective Action in Ant Control
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ravnborg,   Helle Munk; de la Cruz,   Ana Milena; del Pilar Guerrero,   Maria; Westermann,   Olaf.
Leaf-cutting ants (Atta. cephalotes) represents a serious problem to farmers in many parts of Latin America and accounts of ants eating up a whole cassava plot or destroying one or more fruit trees overnight are not uncommon. Ants do not respect farm boundaries. Therefore, farmers who control anthills on their own fields might still face damage on their crops caused by ants coming from neighboring fields where no control measures are taken. In that sense, crop damage caused by leaf-cutting ants constitutes a transboundary natural resource management problem which, in addition to technical interventions, requires organizational interventions to ensure a coordinated effort among farmers to be solved. This paper reports on a research effort initiated by CIAT...

Combating chronic poverty in Uganda: towards a new strategy
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ssewanyana,   Sarah N.
Using a panel of 3,572 households in the Northern Uganda Social Action Fund (NUSAF) region interviewed in 2004 and in 2008, the paper provides new evidence on chronic poverty in Uganda. While progress in reducing poverty rates has been impressive from 64.6 percent to 52.2 percent, the levels remain high with a significant number of persistently poor households. Four in every ten households are chronically poor of which 44.9 percent are living in extreme chronic poverty. About 37.8 percent of the households are living in transient poverty of which 67.4 percent escaped poverty during the panel period. The substantial movements out of poverty can perhaps be explained largely by the relative return of peace in the region that enabled households to engage in...

Combining biophysical and price simulations to assess the economics of long-term crop rotations
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Murray-Prior,   Roy B.; Whish,   J.; Carberry,   Peter S.; Dalgleish,   N.
Long-run rotational gross margins were calculated with yields derived from biophysical simulations in APSIM over a period of 100+ years and prices simulated in @Risk based on subjective triangular price distributions elicited from the Jimbour Plains farmer group. Rotations included chickpeas, cotton, lucerne, sorghum, wheat and different lengths of fallow. Output presented to the farmers included mean annual GMs and distributions of GMs with box and whisker plots found to be suitable. Mean-standard deviation and first and second-degree stochastic dominance efficiency measures were also calculated. Including lucerne in the rotations improved some sustainability indicators but reduced profitability.

Biophysical simulation models (e.g. APSIM) using historical rainfall data are increasingly being used to provide yield and other data on crop rotations in various regions of Australia. However, to analyse the economics of these rotations it is desirable to incorporate the other main driver of profitability, price variation. Because the context was that APSIM was being used to simulate an existing trial site being monitored by a farmer group Gross Margin output was considered most appropriate. Long-run rotational gross margins were calculated for the various rotations with yields (and other physical outputs) derived from APSIM simulations over a period of 100+ years and prices simulated in @Risk based on subjective triangular price distributions elicited...

Duality methods utilizing a profit function framework are employed to estimate the output elasticity of ambient ozone levels on cash grain farms in Illinois.  While duality methods have been recommended as a cure to many of the statistical problems of direct estimation of production functions, multicollinearity may still be a problem.  A method for utilizing stochastic information on parameters of a seemingly unrelated system of equations, which is implied by profit function estimation, is developed and applied to measuring the impact of ozone.  Such an approach may be necessary in measuring other environmental effects because of a lack of regressor variability.

Combining revealed and stated preference methods to assess the private value of agrobiodiversity in Hungarian home gardens
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Birol,   Ekin; Kontoleon,   Andreas; Smale,   Melinda.
Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor. They generate private benefits for farmers by enhancing diet quality and providing food when costs of transacting in local markets are high. Home gardens also generate public benefits for society by supporting long-term productivity advances in agriculture. In this paper, we estimate the private value to farmers of agrobiodiversity in home gardens. Building on the approach presented in EPTD Discussion Paper 117 (2004), we combine a stated preference approach (a choice experiment model) and a revealed preference approach (a discrete-choice, farm household model). Both models are based on random utility theory. To combine the...

The liberalization of foreign trade has positively impacted the production of cereals in Mali. The increase in the production of cereals is due to both price increases and the effectiveness of the marketing system. The liberalization made Mali a cereal exporter in contrast with its former status ten years ago, that of a cereals importer Mali supplies its neighboring countries such as Mauritania, Niger, Burkina Faso, Senegal and Cote d’Ivoire with coarse grains. However, subsidies, rapid urbanization, and changes in the food habits of the urban population threaten Mali’s capacity to remain an exporter. To remain an exporter, Mali should, in the long term, process coarse grains into products conforming to the expectations and food habits of the urban...

Cassava production has grown rapidly in Zambia since the early 1990’s. Available evidence suggests that volumes of traded cassava have been increasing roughly twice as fast as production.  Yet this cassava production boom could stall unless commercial markets for it develop. To help accelerate commercial development of cassava and cassava-based products at the national level, Zambia’s Agricultural Consultative Forum (ACF) initiated an Acceleration of Cassava Utilization (ACU) Task Force, beginning in August 2005. At a regional level, efforts such as the Cassava Transformation in Southern Africa (CATISA) project aim to complement national efforts and help facilitate regional spillovers, so that new products, new technologies or new lessons can help to...

Autores: Kliethermes,   Brandon; Parcell,   Joseph L.; Franken,   Jason R.V.
Little information exists on grain merchandisers, their characteristics, and the skills needed to be successful. This research contributes toward filling this gap. A summary of survey responses from 230 experienced grain merchandisers quantifies personal characteristics, skills perceived as important, and desire for executive education. Parametric analyses identify factors contributing to merchandisers’ salaries and their interest in establishing a certification process. Interestingly, experience but not formal education significantly enhances salaries.

COMMODITY AND CONSERVATION POLICY IMPACTS ON RISK AND RETURNS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hoag,   Dana L.; Young,   Douglas L.
Crop yields, farm income risk and returns, and soil losses were simulated from 1974 to 1984 for southeastern Washington Palouse-region farms in three climatic subregions under alternative conservation and commodity policy scenarios.  Historical commodity programs reinforced preexisting disincentives to retire highly erodible land to perennial grasses, but cropland base protection (CBP) legislation would eliminate such disincentives and increase profitability and decrease risk of land retirement.  Nevertheless, additional incentives would be needed.  Government rental payments can provide necessary incentives, but they are more costly without CBP. CBP was not included in the 1985 farm bill.

Commodity Payments, Farm Business Survival, and Farm Size Growth
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Key,   Nigel D.; Roberts,   Michael J.
In the last 25 years, U.S. crop farms have steadily declined in number and grown in average size, as production has shifted to larger operations. Larger farms tend to receive more commodity program payments because most payments are tied to a farm’s current or historical production, but whether payments have contributed to farm growth is uncertain. This study uses farm-level data from the census of agriculture to determine whether there is a statistical relationship between farm commodity program payments and greater concentration in production. The analysis indicates that, at the regional level, higher commodity program payments per acre are associated with subsequent farm growth. Also, higher payments per acre are associated with higher rates of farm...

COMMODITY PROGRAM SLIPPAGE RATES FOR CORN AND WHEAT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Love,   H. Alan; Foster,   William E.
Slippage rates for corn and wheat are estimated using a simultaneous system explaining per-acre yields, input usage, technical change, and levels of participation in government programs. Soybeans are included due to cross-compliance requirements and because they substitute for corn in production. Slippage rates for wheat are in the range of 29-37% and for corn in the range of 48-58%. The results imply that efficient design of commodity programs must account for the slippage of aggregate yields due to changes in land quality and the use of constrained resources over fewer acres.

Community Action and Pest Control

Several authors have recognised pests as a negative common property resource. As a common property issue, there are often benefits to be gained in regional coordination of pest control activities. Entomologists have also recognised the potential benefits from regional coordination programs and have encouraged areawide Integrated Pest Management (IPM) strategies. However, despite the acknowledgment of differences between individual and regional economic thresholds, studies have not been conducted into the conditions that ensure or prevent collective action in pest control. This is surprising given the vast amount of literature on collective action theory and practice that has accumulated since the work of Mancur Olson. This paper discusses pest control and...

COMPARATIVE ADVANTAGE IN BANGLADESH CROP PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shahabuddin,   Quazi; Dorosh,   Paul A.
This study uses data from 1996/97 through 1998/99 to examine the relative efficiency of production of crops in Bangladesh and their comparative advantage in international trade as measured by net economic profitability (the profitability using economic, rather than financial costs and prices), and the domestic resource cost ratio, (the amount of value of non-tradable domestic resources used in production divided by the value of tradable products). The economic profitability analysis demonstrates that Bangladesh has a comparative advantage in domestic production of rice for import substitution. However, at the export parity price, economic profitability of rice is generally less than economic profitability of many non-rice crops, implying that Bangladesh...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mahlanza,   B.; Mendes,   E.; Vink,   Nick.
In a context in which the framework of agricultural policy and business is changing radically the objective of the government and farmers should be to support the development of systems that look likely to be winners in the future. As a result this paper uses a Policy Analysis Matrix (PAM) to determine whether wheat production would have a comparative advantage if produced under organic practices. The paper starts by analysing the comparative advantage of wheat under conventional  practices, and later contrasts conventional with organic practices. The results of the analyses mainly indicate a comparative advantage for wheat grown under organic practices especially when the social cost benefit ratio (SCB) is incorporated into the analyses. This is because...

Autores: Joubert,   Christo J.; Phahlane,   N.H.; Jooste,   Andre; Dempers,   C.; Kotze,   Louise.
The focus of this research was to investigate the comparative advantage of the potato industry in seven potato production regions in South Africa. Potatoes are the most important vegetable crop produced in South Africa. In 2008 it contributed more than 40% to the total production of vegetables in South Africa and it accounted for more than 20% of the value of all fresh produce sold on all the major national fresh produce markets. This study uses the Resource Cost Ratio (RCR) methodology that provides an explicit indication of the efficiency with which production alternatives uses domestic resources to generate or save foreign exchange. The Nominal Protection Ratio (NPR) and Effective Protection Coefficient (EPC) were also calculated. The results show that...

COMPARATIVE ANALYSIS OF CAPITAL INTENSIVE AND LABOR INTENSIVE RICE IRRIGATED PERIMETERS IN THE SENEGAL RIVER VALLEY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Diallo,   Mamadou Dian.
Senegal is heavily dependent on imported food, particularly rice.  During the late sixties and early seventies the Sahelian drought made the country painfully aware how dependent its agriculture is on rainfall.  Irrigation and full water control systems along the major rivers became the "priority of priorities" in the recent Senegalese national plans.  In the Senegal River Valley two major types of irrigation schemes had been implemented along the river valley since 1973:  large scale and small scale irrigated perimeters.  The objectives are to increase rice production and reduce dependence on foreign imports of rice.  This paper analyzed the two types of irrigation schemes in the Senegal River Valley and compares the financial and economic cost of...

COMPARATIVE ANALYSIS OF RICE PRODUCTION COSTS IN SMALL- AND LARGE-SCALE IRRIGATED PERIMETERS IN THE UPSTREAM ZONE OF THE FLEUVE, MAURITANIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Koita,   Tocka.
Some agricultural project analysts advocate that "small-scale" perimeters are more cost effective and successful than large ones.  Patterson argues that the small scale perimeter if potentially conducive to development because of their smallness and their flexibility in terms of innovations.  Morever a recent survey irrigation in the Sahelian countries by Stryker, Gotsch, McIntire and Roche, suggests that labor intensive schemes generally have better distributional characteristics than those that are more capital intensive.  These advantages attributed to the small schemes have even biased some donors towards funding small scale perimeters. Efforts to expand rice production and therefore to increase self-sufficiency can be analyzed in terms of their...

Comparative Performance of Organic, Conventional, and Integrated Producers in New Zealand
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Greer,   Glen; Kaye-Blake,   William; Hunt,   Lesley.
The Agriculture Research Group on Sustainability (ARGOS) monitors a wide ange of environmental, social, economic and management parameters on matched cohorts of organic, conventional and integrated farms in the sheep/beef and kiwifruit sectors. Over six years significant differences have been found in farm costs and revenues between management systems, but few differences have been identified between management systems in “bottom-line” indicators of profitability, and there is greater variability within cohorts than between them. Regrouping of the properties according to farmer typologies does, however, result in the identification of some significant differences in economic outcomes between different “types” of farmers.

Comparing Accuracy and Costs of Revealed and Stated Preferences: The Case of Consumer Acceptance of Yellow Maize in East Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kimenju,   Simon Chege; De Groote,   Hugo; Morawetz,   Ulrich B.
For quite a while, stated preferences have been a major tool to measure consumer preferences for new products and services. Revealed preference methods, in particular experimental economics, have gained popularity recently because they have been shown to be more incentive compatible, and therefore more accurate. However, this advantage comes at the expense of higher survey costs. In the developing countries with limited funding for research, it is important to determine whether the extra cost can be justified by the extra gain in accuracy. A survey of 100 farmers was carried out in Western Kenya to determine consumer preference for yellow maize using the contingent valuation, choice experiments and experimental auction methods. Experimental auctions...

COMPARING END-USE VALUES FOR NORTH DAKOTA HARD RED SPRING WHEAT VARIETIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lambert,   David K.; Wilson,   William W.
Markets for agricultural products may be inefficient when signals do not adequately reflect product characteristics important to market participants.  Although preferences can be explicitly stated through price premiums or characteristic values can be determined via hedonic methods, the problem is compounded when product quality information is costly to obtain.  Bundling of quality traits by variety can serve to signal product quality.  A procedure is developed in this paper to derive the value of different varieties in meeting buyer demands.  An application to the hard red spring market wheat both validates the ability of the procedure to distinguish among varieties, as well as provides empirical support to the existence of Akerlof's lemon market in the...

Comparing Farm and Village-Level Determinant of Millet Diversity in Marginal Environments of India: The Context of Seed Systems
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nagarajan,   Latha; Smale,   Melinda; Glewwe,   Paul.
The purpose of the research paper is to characterize biological diversity related to millets in the semi-arid regions of India at various spatial scales of analysis (e.g., farm household versus community levels) and place that evidence in a broader seed systems (includes both formal and informal) context. An important finding of this research is that producer access to millet genetic resources is affected by the extent to which seed is traded via formal markets or through other social institutions, along with farm and household characteristics. Findings also underscore the need for an enhanced theoretical understanding of local seed markets in analyzing crop variety choices and the diversity of materials grown in less favored environments.

Comparing the effects of different approaches to liberalising world grains markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hirad,   Hagi; Nelson,   Rohan; Andrews,   Neil; Shaw,   Ian.
The success of the current Doha Round of the WTO negotiations on agriculture will require substantial reform in each of the three areas of market access, export subsidies and domestic support. Substantial improvement in market access for agricultural products will be an essential requirement for achieving a successful outcome. However, the extent of improvement in market access resulting from the current negotiations will largely depend on the form and the approach followed to reduce tariffs and expand tariff rate quotas. In this paper different approaches to expanding market access for grains area analysed using a partial equilibrium model. Simulated scenarios include linear reductions in applied tariffs and expansions in tariff rate quotas, which are...

COMPARING THE PROFITABILITY OF CASSAVA-BASED PRODUCTION SYSTEMS IN THREE WEST AFRICAN COUNTRIES: COTE D'IVOIRE, GHANA AND NIGERIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Camara,   Youssouf; Staatz,   John M.; Crawford,   Eric W.
Sub-Saharan Africa (SSA) cassava-producing countries such as Nigeria, Ghana, and Côte d'Ivoire have developed, in recent years, a renewed interest in cassava as an alternative food crop.  This has led to a major expansion in cassava-based production systems in Nigeria and Ghana, whereas there has been a slower growth in Côte d'Ivoire (Nweke et al., 1998).  This paper is based on the argument that the difference in various factors such as agricultural policies (i.e., trade and price policies, domestic production taxes or subsidies), location and technologies (production and processing) between Nigeria, Ghana and Côte d'Ivoire the difference in the level of growth in cassava-based production systems.  The paper examines, using the Policy Analysis Matrix...

Autores: Browne,   Natalie; Kingwell,   Ross S.; Behrendt,   Ralph; Eckard,   Richard.
Dryland farming is commonplace in Australia so the profitability of dryland farms often depends on the amount and timing of rainfall. With drier weather conditions featuring in climate change projections for southern Australia, it is important to understand the relationships between rainfall, commodity prices and farm profitability. Using correlated farm commodity and input prices from the past nine years, farm profitability was calculated for a range of farm types in southwest Victoria under low, average and high rainfall scenarios. Fourteen representative farms were examined that included production of Merino fine wool, prime lamb, beef cattle, milk, wheat and canola. This paper compares and contrasts the spread of profitability of these farms against...

Comparing Welfare Estimates from Fixed Status Quo Attributes vs People’s Perceived Attributes of Water Quality
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marsh,   Dan; Mkwara,   Lena Asimenye.
Data from a choice experiment on the community’s preferences for water quality improvements in streams was used to assess the effect of using a fixed status quo versus people’s perceived status quo on willingness to pay values. More than 50% of respondents perceived the quality of water in streams to be different to the status quo in the initial experimental design. Study results have shown that respondents who opted for their own perceived status quo alternative had stronger preferences and higher willing to pay for water quality improvements than their counterparts.

The aim of this study was to compare production and policy risk of organic, integrated and conventional cropping systems in Norway. Experimental cropping system data (1991-1999) from eastern Norway were combined with budgeted data. Empirical distributions of total farm income for different cropping systems were estimated with a simulation model that uses a multivariate kernel density function to smooth the limited experimental data. Stochastic efficiency with respect to a function (SERF) was used to rank the cropping systems for farmers with various risk aversion levels. The results show that the organic system had the greatest net farm income variability, but the existing payment system and organic price premiums makes it the most economically viable...

Discounts and premiums for wheat quality factors at a specific location can be affected by the quality of wheat at other locations. We estimate the effects of protein and test weight levels of Kansas hard red winter and North Dakota dark northern spring wheat on the protein and test weight premiums of each other. Additionally, we determine the effect on premiums of protein and test weight and discounts of shrunken/broken and damaged kernels at different locations within each region from changes in wheat qualities at other locations within the same region. Results indicate that spatial competition was important for protein and test weight, both between the two wheat regions and within the same region.

Competitiveness of Kenyan and Ugandan Maize Production: Challenges for the Future
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nyoro,   James K.; Kirimi,   Lilian; Jayne,   Thomas S.
The purpose of this study is to assess the costs of maize production in Kenya and Uganda, starting from the fact that there is no single “cost of production” for maize. Cost of production varies according to region, the type of technology package employed, farmers’ management practices, and the weather. In light of this, the study disaggregates cost of production into seven region/technology categories, five in Kenya and two in eastern Uganda, in order to compare the relative competitiveness of maize among these regions and technology packages. Variations in cost of production within each region/technology category reflect differences in farmer management practices and micro-variability in soils and rainfall.

COMPLIANCE WITH EUREPGAP STANDARDS: DETERMINANTS, COSTS AND IMPLICATIONS ON PROFITABILITY AMONG SMALLHOLDER FRENCH BEANS EXPORTERS IN KIRINYAGA DISTRICT, KENYA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Muriithi,   Beatrice Wambui.
Horticulture provides many developing countries with opportunities for export diversification, poverty alleviation and rural development. However, stringent public and private-sector food-safety standards, for example EurepGap, pose a challenge especially to small export farmers. Compliance with these standards entails costly investments that may be a burden to smallholder farmers, failure to which might lead to their exclusion in the global market. A number of questions which require empirical research arise to confirm or refute these concerns. The study assesses awareness of the EurepGap standards among smallholder farmers and analyzes the critical factors influencing their compliance. It also identifies the costs of complying with these standards and...

Components of Grain Futures Price Volatility
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Karali,   Berna; Thurman,   Walter N.
We analyze the determinants of daily futures price volatility in corn, soybeans, wheat, and oats markets from 1986 to 2007. Combining the information from simultaneously traded contracts, a generalized least squares method is implemented that allows us to clearly distinguish among time-to-delivery effects, seasonality, calendar trend, and volatility persistence. We find strong evidence of time-to-delivery (Samuelson) effects and systematic seasonal components with volatility increasing prior to harvest times— an indirect confirmation of the theory of storage.

Autores: Mitchell,   Paul D.; Gray,   Michael E.; Steffey,   Kevin L.
This paper describes a composed error model for estimating the conditional distribution of yield loss to serve as an insect damage function.  The two-part error separates yield variability due to pest damage from other non-pest factors such as soil heterogeneity, non-uniform application of agronomic practices, and measurement errors.  Various common functional forms (linear, quadratic, Cobb-Douglas, negative exponential, hyperbolic, sigmoid) for the pest damage function are presented and parameter estimation is described. As an empirical illustration, the model is used to estimate a damage function for corn rootworm, the most damaging insect pest of corn in the United States.  The estimated damage function gives expected proportional yield loss as a...

Computing Average Per Acre Indemnity Payments for Corn in Iowa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hart,   Chad E.; Smith,   Darnell B.
This study estimates average per acre indemnity payments for Iowa corn for traditional multiple-peril crop insurance and two new revenue insurance products, Crop Revenue Coverage and Income Protection. Yield and price difference distributions are formed and employed in 1,000 simulation runs.  From these simulations, corn yields for all 99 Iowa countries and futures prices are collected.  These are used to calculate per acre indemnities under the three insurance products.  Income Protection has the smallest per acre indemnities across the state, followed by multiple-peril and Crop Revenue Coverage.  Per acre indemnities are the lowest in northwest Iowa and highest in southeast Iowa.

Computing Opportunity Costs of Growing Local Varieties for On-farm Conservation: Illustrations Using Sorghum Data from Ethiopia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wale,   Edilegnaw; Mburu,   John G.; Estrella,   Jaime.
The recent shift of emphasis to on-farm conservation is driven by its diverse attractive features - participatory nature, dynamic nature, capacity to maintain not only crop diversity but the knowledge that evolves with it, the chance it offers and the challenge it brings to link conservation with farmers' livelihood. To make it operational, placing incentives and removal of perverse incentives are of critical importance. However, before placing sound incentives compatible to farmers' circumstances, the opportunity costs farmers face when using local varieties of public interest should be understood. This paper empirically examines farmers' opportunity costs of maintaining local varieties of sorghum using a household survey data collected from 198 sorghum...

Much water has flowed under the bridge since ministers failed to conclude world trade negotiations in July 2009. The world underwent an historical recession brought about by the U.S. financial toxic asset scandal. Global trade has declined sharply and is forecasted to decline by 9% in real terms in 2009. World economic growth rates have declined dramatically. There have been several cases of covert (and some overt) protectionism by both developed and advanced economies. Despite declarations from world leaders on several occasions for the need to refrain from protectionist measures and the need for the resumption and conclusion of the Doha Round of trade negotiations over the past nine months, no such action has materialized. The two major contestants in...

While agricultural economics literature has become rife with the economics of ethanol production and cellulosic ethanol feedstock production, little has been written about capital investment necessary for the magnitude of industry development mandated by the Energy Security and Independence Act of 2007. Financing the development of the ethanol industry to meet the 36 billion gallon production capacity set for 2022 (with 16 billion gallons from cellulosic ethanol) will require capital investments exceeding $100 billion for production facilities, plus extensive investment in feedstock establishment and transportation/handling infrastructure.

Conservation impediments and incentives – progressing the understanding of linkages between the adoption of conservation practices and the motivational orientation of graziers in the tropical savannas
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gregg,   Daniel; Greiner,   Romy.
The adoption of conservation practices is a complex matter – rural landholders consider a wide variety of factors and characteristics when deciding whether to adopt a conservation practice. To confound the issue, recent research has suggested that the goals of landholders affect the adoption of conservation practices by creating a subjective consideration of the relative importance of impediments and effectiveness of incentives in the adoption decision. In this research we describe an empirical link between graziers’ goals and their perceptions of the relative importance of impediments and the effectiveness of incentives in the adoption of conservation practices. The research was carried out in the tropical savannas region of Australia where pastoral...

CONSERVATION TILLAGE AND PESTICIDE USE IN THE CORNBELT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fuglie,   Keith O.
Adoption of conservation tillage can lead to substantial environmental benefits from reduced soil erosion.  But benefits may be partially offset if adoption increases reliance on agricultural chemicals.  Using area study data from the Cornbelt, this study examines factors affecting adoption of no-till and other conservation tillage systems and their effect on chemical use and corn yield.  The results find no evidence that herbicide or fertilizer application rates are higher on fields with conservation tillage systems compared with conventional tillage.  However, insecticide use may increase somewhat and yield may be lower.  Current demographic trends in U.S. agriculture favor continued diffusion of conservation tillage.

CONSIDERATIONS IN THE INTRODUCTION OF CROP INSURANCE TO RICE SECTOR IN KOREA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lee,   Kwan Yong.
Agricultural production depends much on uncontrollable weather conditions, which often threatens farmers' livelihoods.  Weather risks are especially important for farmers in developing countries where they are still cultivating with conventional methods and less well developed irrigation and drainage systems and equipment.  Moreover, seasonality and cyclicality hinder growth of agricultural sectors and make farm households' incomes unstable. Two measures for dealing with such problems in the agricultural sector include 1)   Governmental price intervention and the expansion of farming bases, and 2)  the establishment of governmentally run agricultural disaster insurance.  As stated later, even though government plays a major role in an agricultural...

Water for irrigation and irrigation infrastructure are both common pool resources, due to their low excludability and high rivalry. The wellknown common pool resource dilemma is often the consequence. Collective action may be a way how societies can overcome this dilemma. First results from a three-month empirical field study in Bulgaria are presented trying to explain how actor groups characteristics, such as lack of trust between community members and effective institutional settings at the local level, such as information asymmetry, limited sanctioning and enforcement mechanisms and almost no monitoring mechanisms provide conditions under which opportunistic behaviour dominates.

Constructing Farm Level Yield Densities from Aggregated Data: Analysis and Comparison of Approaches
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cooper,   Joseph C.; Langemeier,   Michael R.; Schnitkey,   Gary D.; Zulauf,   Carl R.
Yield variability can be significantly higher at the farm level than at more aggregated levels, including the county. However, due to a dearth of available farm level data, much stochastic analysis involving farm yields utilizes more aggregated yield data as a proxy for the farm level.  We empirically evaluate farm-level variability using longitudinal farm level data sets available from the Kansas Farm Management Association and the Illinois Farm Business and Farm Management Association.  For corn, soybeans, and wheat, we compare the farm level yield variability obtained from this data to that inferred from Federal crop insurance premiums.  The farm management data exhibit lower yield variability than are implied by the crop insurance premiums.

Consumer Acceptance of Genetically Modified Food Products in the Developing World
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Curtis,   Kynda R.; Wahl,   Thomas I.; McCluskey,   Jill J.
World-wide consumer response toward food products made from genetically modified ingredients has been largely negative. However, the majority of the previous studies on consumer attitudes towards genetically modified food products were conducted in developed countries in Europe as well as Japan. The small number of studies conducted in developing countries obtained different results from the developed world. This paper considers the motivations for consumer attitudes towards genetically modified foods in developing countries. We conclude that the generally positive perception towards genetically modified foods in developing countries could be the result of a cost-benefit analysis consistent with expected utility theory. Developing countries have more...

Issues concerning consumer demands for genetically modified and organic food remain topical. It is unclear how consumers perceive issues associated with food production such as food safety, environmental impacts or animal welfare. It is also unclear how consumers might value potential changes in those issues in regional and metropolitan centres. This paper reports on research using the choice modelling technique to estimate and compare consumer demand for genetically modified and organic foods in Australia. The case study considers tomatoes, milk and beef commodities. The results draw comparisons between the contribution of associated factors influencing consumer purchasing decisions in a regional and metropolitan city. The results are relevant to the...

Autores: Hinson,   Roger A.; Bruchhaus,   Michael N.
Consumers were surveyed to understand preference in an effort to stabilize acreage and market share in a minor strawberry production area. Preferred attributes were identified using conjoint analysis. Local product was highest in overall relative importance, followed by price, pesticide strategy, and container. Cluster analysis identified groups with similar demographics. For two groups, local product was 77 percent and 67 percent of relative importance; for another group, price was about 75 percent of importance; while the final group was balanced across three attributes. Alignment with consumer preferences and with strategies of local retailers and wholesalers lead to suggested tactics to support local product.

Increase in urban middle income consumers along with consolidation of the retail sector has created changes in olive oil consumption preferences in Albania. The objective of this study is to inform stakeholders in the olive oil industry about consumer preferences. A Conjoint Choice Experiment (CCE) was used to design the survey and latent class approach used to analyze the data. The results show a strong preference for domestic olive oil and small niche markets that cater to specific consumers. The study also shows a gap between preference and reality that needs to be addressed by the stakeholders in the olive oil industry.

Consumer Response to Integrated Pest Management and Organic Agriculture: An Econometric Analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Govindasamy,   Ramu; Italia,   John.
While several studies have presented aggregate, descriptive illustrations of consumer response to IPM, the willingness-to-purchase and willingness-to-pay for IPM produce as a function of demographic characteristics has not received the exhaustive research attention that has focused on organic produce. The objective of this study was to empirically evaluate which demographic characteristics cause consumers to be more likely to purchase IPM grown produce. A hypothetical willingness-to-purchase model for IPM produce as well as willingness-to-pay models for both IPM and organic produce are presented. A non-hypothetical analysis also predicts consumers who strictly purchase only conventional produce. Income was found to be the most significant determinant of...

CONSUMER WILLINGNESS TO PAY FOR MULTIPLE ATTRIBUTES OF ORGANIC RICE: A CASE STUDY IN THE PHILIPPINES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ara,   Shihomi.
Organic rice production in the Philippines has been growing rapidly since 1986. We conducted a conjoint analysis to determine consumers' preferences of multiple attributes of organic rice in Manila and Naga city. Attributes included were price, reduced health risk level, environmental quality, eating quality, type of organic certification and a fair trade factor. In both cities, health risk was the primary concern. Consumers in Manila revealed organic certification to be the second most important factor while improvement of the farm environment was the second highest factor in Naga city. We found that consumers who live further from the production site have a higher demand for certification. On the other hand, consumers who live close to farms care more...

Autores: Kim,   Sounghun; Son,   Eun-Young; Park,   Sungho.
This paper conducts several analyses to discuss about consumers' preference of rice brands and suggest a way to reduce the number that currently stands at about 1,700 in the Korean market. With data collected from 358 survey respondents, a conjoint analysis was conducted to identify consumers' preferences of Korean rice in regard to such aspects as producing area, brand, category, and price. We particularly focused on analyzing the consumers' preference of rice brands, with some scenarios to decrease the number of brands.  The paper also estimated the virtual market shares of rice brands. As results of the analyses, the paper shows that the grouping of individual rice brands in a city or county under one representative brand is the most preferred by Korean...

Consumers responded to the Food and Drug Administration’s September 2006 warnings to avoid eating spinach because of possible contamination with E. coli O157:H7. While spinach expenditures fell, consumers turned to other leafy greens as substitutes. The longer term drop in retail expenditures on fresh spinach products was almost matched by gains in expenditures on other leafy greens.

This article summarizes a study of consumers' willingness to pay (WTP), in urban areas in Tennessee, Mississippi, and Michigan, for a powdery mildew resistant dogwood tree. Powdery mildew is a disease affecting flowering dogwoods that can limit growth, detract from the appearance, and may cause plant decline and death.  Study objectives were to provide information about consumers' WTP and to identify potential marketing strategies for the introduction of the disease-resistant tree. On average, survey respondents indicated they are willing to pay a $13.35 premium for a flowering dogwood tree which is resistant to powdery mildew. Regression results led to inferences that the presence of dogwoods in a respondent's yard, presence of dogwoods infected with...

CONSUMERS' VALUATION OF INSECTICIDE USE RESTRICTIONS: AN APPLICATION TO APPLES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Roosen,   Jutta; Fox,   John A.; Hennessy,   David A.; Schreiber,   Alan.
Economic assessments of pesticide regulations typically focus on producer impacts and generally ignore possible changes in product demand. These changes may be nonnegligible if real and/or perceived product attributes change. We measure consumers’' willingness to pay (WTP) for the elimination of one insecticide and also a whole group of insecticides in apple production using a multiple-round Vickrey auction. The data are analyzed using nonparametric statistical tests and a double-hurdle model. Our findings show that consumer perceptions of product attributes change if pesticides are removed from production, and this is reflected in WTP changes. WTP is shown to be income elastic.

Consumers’ Willingness to Pay for Food Safety in Nairobi: The Case of Fresh Vegetables
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lagerkvist,   Carl Johan; Hess,   Sebastian; Ngigi,   Marther W.; Okello,   Julius Juma.
Large urban areas in developing countries represent currently the most dynamically growing markets for food products. This study investigates the willingness to pay of consumers in Nairobi for safer leafy vegetables. We survey individuals’ perceived food safety across four major market categories, while also considering the explanatory role of trust and behavioral, psychological, and socio-demographic covariates. Results show that willingness to pay is market-specific and multi-faceted, with trust and perceived risks as important drivers, while income plays only a subordinate role. We conclude that policy makers should aim to reduce asymmetric information within the value chain without raising food prices such that safer vegetables would become...

Consumers' Willingness to Pay for Treatment-Induced Quality Attributes in Anjou Pears
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zhang,   Huifang; Gallardo,   Rosa Karina; McCluskey,   Jill J.; Kupferman,   Eugene M.
Ethylene treatments provide an effective method for shortening post-harvest ripening periods for winter Anjou pears and allow market availability throughout the year. However, pear quality may vary under different treatments. A sensory experiment and a consumer survey including questions that address valuation, assessments of sensory characteristics, purchasing habits, and demographics were conducted. Analyses indicate that treatment-induced quality losses significantly affect consumers’ willingness to pay (WTP). Mean WTP for each treatment reveals that consumers prefer pears with a six-day ethylene treatment and are willing to pay a premium of $0.25/pound compared to the market price.

Decades of Soviet rule have left a heritage of environmental and social problems in Central Asia. The demise of an entire ecosystem at unprecedented pace, the "Aral Sea Syndrome", is the most prominent of the undesired outcomes of the focus on agricultural production that has dominated land and resource use and continues till today. The international outcry over this ecological crisis has delegated other – and maybe more urgent – problems to a second pane. Rural livelihoods are rapidly deteriorating, unemployment is high, and rural poverty widespread. Ecological aspects, although strongly affecting everyday life in rural areas – such as water and soil salinity and environmental pollution – are not the fore most concern to the local population, as the...

This study examines incentives for input use under tournament contracts. We analyze implications of contract design for nitrate-based environmental externalities generated by agricultural producers. Outcomes are compared from contracts awarded by tournament to those from fixed-payment contracts. Our findings show contract insecurity can distort input use. The model developed in this analysis is applied to a region of the U.S. where tournament-based production is prevalent and groundwater contamination is a problem. We find contract insecurity increases nitrogen use by about 12%, resulting in a 17% increase in nitrate leaching. Implications for contract modification to reduce environmental externalities while maintaining contract incentives are discussed.

CONTRACT MARKETING IN THE US AFTER THE 2002 FARM ACT: THE CASE OF PEANUTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Revoredo-Giha,   Cesar; Nadolnyak,   Denis A.; Fletcher,   Stanley M.
The elimination of the marketing quota system that regulated the peanut market since the 1930s has been accompanied by the emergence of marketing contracts between farmers and peanut buyers (mainly peanut shellers). Two types of contracts have been observed, forward contracts for delivery at harvest or at a later date and “option to purchase” contracts. We analyze the clauses of contracts used by major shellers in order to infer the motivation behind these contracts (i.e., risk sharing, reduction of transaction costs, improve coordination, exercise of market power, etc.). The analysis points out that the main role of the contracts is to replace the marketing structure existing prior the 2002 Farm Act, where peanut marketing was quite regulated. In this...

Autores: Wilson,   William W.; Dahl,   Bruce L.
Canola has become an important crop in the last decade in the U.S. Production of canola is risky and competes with other crops which have a range of risk reduction mechanisms. Alternative contracting strategies were evaluated by comparing returns to labor and management for growers and gross margins for processors. Alternative contracting strategies included no contract, fixed price with and without act of god provisions, and an oil premium contract. Grower returns and processor gross margins were simulated and resulting distributions were evaluated using stochastic efficiency with respect to a function. We estimated certainty equivalents and ranked contract preferences for both growers and processors by region in North Dakota. Grower and processor risk...

Contracts for Grain Biosecurity and Grain Quality
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Abougamos,   Hoda; White,   Benedict; Sadler,   Rohan.
The export of grain from Western Australia depends upon a grain supply network that takes grain from farm to port through Cooperative Bulk Handling receival and storage sites. The ability of the network to deliver pest free grain to the port and onto ship depends upon the quality of grain delivered by farmers and the efficacy of phosphine based fumigation in controlling stored grain pests. Phosphine fumigation is critical to the grain supply network because it is the cheapest effective fumigant. In addition, it is also residue free. Unfortunately, over time, common stored-grain pests have evolved to develop resistance to phosphine and there is a risk that phosphine will become less effective and may need to be replaced with more expensive alternative...

Cassava production in Benin is still characterized by low productivity compared to those of sub regional countries. Improved cassava varieties have been then developed. They have been promised to raise the productivity and thereby the income of farmers. This study examines the relationship between agricultural technology adoption and productivity improvement with focusing on high yield cassava varieties. The data used were collected from 267 randomly selected cassava producers in Benin. The paper uses the counterfactual outcomes framework of modern evaluation theory to estimate the Average Treatment Effect (ATE) of high yield cassava varieties adoption on farm-level average yield. Results indicate that the adoption of high yield cassava varieties...

The impact of wheat diversity on the productivity of wheat in China is examined using total factor productivity (TFP) and an instrumental variable approach.  TFP in seven key wheat-producing provinces in China shows significant, though variable, growth for all provinces during the period 1982-1995.  Analysis of the causes of TFP growth tests alternative taxonomies of wheat diversity (named varieties and morphological groups) and three measures of diversity.  The analysis shows significant effects of diversity on TFP with results consistent across taxonomies and measures of diversity.  Further decomposition of the estimation results confirms the relative magnitude of impact of wheat diversity on TFP growth.

Contributions of Immigrant Farmworkers to California Vegetable Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Devadoss,   Stephen; Luckstead,   Jeff.
A major concern with immigrants coming into the United States is that they adversely affect domestic workers through job competition and wage depression.We study the displacement and wage reduction effects of immigrants in California vegetable production, which is labor intensive, and 95% of the farmworkers in California are immigrants. Our findings show that this concern is not valid in vegetable production because the addition of one new immigrant displaces only 0.0123 domestic workers, and wage reduction is inconsequential. But one immigrant worker increases the vegetable production by $23,457 and augments the productivity of skilled workers, material inputs, and capital by $11,729.

Contributions of U.S. Crop Subsidies to Biofuel and Related Markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Devadoss,   Stephen; Bayham,   Jude.
The U.S. crop subsidies provide incentives for farmers to expand feedstock production, which benefits the biofuel producers by lowering input costs. This study develops a general equilibrium model to analyze the effects of a reduction in the U.S. crop subsidy on biofuel industries and social welfare. The impacts of feedstock policies on the biofuel market are marginal. In contrast, the biofuel mandate has a larger impact and counteracts the effects of the crop subsidy reduction. The mandate increases the demand for feedstock and causes not only grain ethanol, but also cellulosic ethanol production to rise. The mandate exacerbates the distortion, and government spending increases significantly, leading to greater welfare loss.

The ACIAR-managed project CS1/1996/013, Herbicide-resistant weeds of wheat in India and Australia: integrated management, was designed to find a long-term method of control of Phalaris minor, a problem weed of the rice–wheat cropping system of north-western India. By 1993, the weed had developed resistance to isoproturon, a herbicide which had delivered effective weed control for 15 years. The short-term solution, implemented before the ACIAR project commenced, involved identification and registration of a new set of herbicides. But these new herbicides were expensive. To ensure high adoption they needed to be combined with changes in wheat-growing techniques that would provide cost savings to help farmers pay for them. And to avoid the re-emergence of...

Converting to organic farming in France: Is there a selection problem?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Latruffe,   Laure; Nauges,   Celine.
Using a sample of French crop farms during the 1999-2006 period, we test whether less technically efficient farmers are more likely to engage in organic farming in order to benefit from conversion subsidies. Despite some limitations in our data, we find no evidence of such selection effect. On the contrary, our estimation results indicate that more technically efficient farmers are more likely to convert to organic farming. This finding is found to be robust to the method of calculation of efficiency scores, either parametric or non-parametric. This study also confirms that farm’s characteristics (education, farm size and legal status) and farmers’ practices under conventional farming do impact the probability of conversion to OF.

Drought is a major constraint affecting rice production especially in rainfed areas of Asia. Despite its importance in rice growing areas, the magnitude of economic losses arising from drought, its impact on farm households and farmers' drought coping mechanisms are poorly understood. This paper provides insights into these aspects of drought based on a cross-country comparative analysis of rainfed rice growing areas in China, India and Thailand. The economic cost of drought is found to be substantially higher in eastern India than in the other two countries. Higher probability and greater spatial covariance of drought and less diversified farming systems with rice accounting for a large r share of household income are likely to be the main reasons for...

Coping with ex ante Regulations and ex post Liability Rules for Planting Bt-maize – The Portuguese Experience
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Skevas,   Theodoros; Fevereiro,   P.; Wesseler,   Justus.
This study investigates the attitude and practices of GM and non-GM maize farmers in Portugal. Thirty seven GM maize farmers were interviewed representing 22.5% of the total number of GM maize notifications in the country. Additionally, 66 non-GM maize farmers were surveyed in an attempt to investigate their opinion on the Bt technology, its viability and its future. The most interesting finding is that almost half of all the surveyed maize farmers (GM and non-GM) stated that the ex ante regulations are rigid and difficult to apply. On the contrary, the ex post tort liability rules are very clear and provide the appropriate security for the continuation of the GM maize cultivation.

Coping with the “Coffee Crisis” in Central America: The Role of the Nicaraguan Red de Protección Social
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Maluccio,   John A.
The international and local Nicaraguan media have widely reported on the “coffee crisis” in Latin America and there is substantial evidence that there has been a downturn and that this has been more severe in the coffee-growing regions. Using household panel data from a randomized community-based intervention carried out in both coffee- and noncoffee-growing areas, I examine the role of a conditional cash transfer program, the Red de Protección Social (RPS), during this downturn. While not designed as a traditional safety net program in the sense of reacting or adjusting to crises or shocks, RPS has performed like one, with larger estimated program effects for those who were more severely affected by the downturn. For example, it protected households...

Autores: Rausch,   Kent D.; Belyea,   Ronald L.; Singh,   Vijay; Tumbleson,   M.E.
Increase in demand for ethanol as a fuel additive has resulted in growth in ethanol production. Ethanol is produced from corn by either wet milling or dry grind processing. In wet milling, the corn kernel is fractionated into different components, resulting in several coproducts. Wet mill plants are capital intensive because of equipment requirements and typically are corporate owned. In dry grind processing, the corn kernel is not fractionated and only one coproduct, distillers dried grains with solubles (DDGS), is generated. Dry grind plants require less equipment and capital than wet mills. They typically are producer owned and add direct benefits to rural economies. Most of the increase in ethanol production during the past decade is attributed to...

Cost Efficiency and Scope Economies of Crop and Livestock Farms in Missouri
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wu,   Shunxiang; Prato,   Anthony A.
This study investigates productive efficiency for a sample of Missouri crop-only (specialized) and integrated crop-livestock (diversified) farms using a cost frontier approach. Results suggest that significant cost inefficiency exists among sample farms. Lower cost efficiency in both types of farms was attributed to improper scale of operations and mis-allocation of inputs. On average, diversified farms were as technically and scale efficient as specialized farms. Lower allocative efficiency diluted gains in technical efficiency and resulted in greater cost inefficiency for diversified farms than for specialized farms. Technical efficiency was independent of farm size, whereas allocative, scale, and scope efficiencies were not.

COST OF SEGREGATING NON-TRANSGENIC GRAINS AT COUNTRY ELEVATORS IN SOUTH DAKOTA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Qasmi,   Bashir A.; Van der Sluis,   Evert; Wilhelm,   Clayton J.
Genetically modified grains have rapidly become popular among producers across U.S.  Some consumers, particularly in the EU, South Korea, and Japan, are unwilling to purchase products containing ingredients from genetically modified or transgenic crops.  This paper develops a model to represent costs of segregating non-transgenic grains at country elevators and simulates these costs at representative elevators in South Dakota under alternative scenarios employing a case study approach. The overall cost of segregating non-transgenic grains under a zero rejection rate ranged from 1.5 to 21.7, 1.2 to 11.3, and 1.3 to 16.4 cents per bushel, for corn, soybeans, and wheat, respectively.

Autores: Cooke,   Stephen C.; Sundquist,   W. Burt.
The purpose of this paper is to estimate the cost structures and resource productivities involved in production of four major U.S. field crops and to estimate the distribution among producers of benefits from production related technology. These field crops include corn, soybeans, wheat and cotton grown in selected homogeneous soil and rainfall areas of the U.S. The cost structure of each commodity is estimated relative to a Cobb-Douglas cost function. Productivity is assessed across time, regions and size of enterprise. The distribution of technology benefits is determined by region and enterprise size for each commodity.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McDonald,   Scott; Punt,   Cecilia; Rantho,   Lillian; van Schoor,   Melt.
Low international wheat prices, caused by tariffs and subsidies in developed countries, have been blamed for causing financial difficulty to South African farmers. While indignation at unfair trade practices may be valid, it does not necessarily follow that protection of the local industry is the best response. This study uses a static general equilibrium model to describe and quantify the effects of increased tariffs (by up to 25 percentage points) on the local wheat industry, other affected industries-- particularly downstream industries-- and the economy at large. The effects on factors, households and the government are also analysed. The results show that the benefits to the wheat industry are highly concentrated and smaller than the loss of income...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Babcock,   Bruce A.; Barr,   Kanlaya J.; Carriquiry,   Miguel A.
The U.S. ethanol industry is lobbying hard for an extension of existing ethanol import tariffs and blenders tax credits before they expire at the end of 2010. The purpose of this study is to examine the likely consequences on the U.S. ethanol industry, corn producers, taxpayers, fuel blenders, and fuel consumers if current policy is not extended. Impacts of different ethanol policies in both 2011 and 2014 were estimated.  Estimates were obtained by developing a new stochastic model that calculates market-clearing prices for U.S. ethanol, Brazilian ethanol, and U.S. corn. The model is stochastic because market-clearing prices are calculated for 5,000 random draws of corn yields and wholesale gasoline prices.   Key assumptions in this study are that the...

Truck transportation has become very important to the North Dakota grain industry. Identification of the costs and characteristics of exempt motor carriers allowed evaluation of the performance of the industry. Average mileage per vehicle was about 88,000 per year. Firms larger than four trucks achieved higher annual mileage as well as larger percent of return trip that was loaded (59 percent compared to 25 percent for the smaller firms). Seventy-eight of the firms had been in business five years or more. Costs per operating mile appeared to be about 92 cents for the industry. Larger firms had a four cent per mile advantage over smaller firms. Three conclusions were: The industry has become more mature and stable in the past five years after experiencing a...

COSTS AND RISKS OF CONFORMING TO EU TRACEABILITY REQUIREMENTS: THE CASE OF HARD RED SPRING WHEAT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   William W.; Henry,   Xavier; Dahl,   Bruce L.
Stochastic simulation was used to determine the marginal cost and optimal testing strategy (location and intensity) for an integrator conforming to proposed European Union traceability requirements for imported hard red spring wheat.  Cost, risks and premiums were determined for exports of non-genetically modified (non-GM) wheat from the U.S. to the EU.  Cost components include certified seed, certification and auditing, testing, traceability, quality loss, and a risk premium for the added risk of a dual traceability system over a single non-traceability system.  The optimal strategy is the one that maximizes the integrator's utility (minimizes disutility of integrator's additional costs).  Adventitious commingling is defined stochastically.  Results...

COSTS AND RISKS OF TESTING AND SEGREGATING GM WHEAT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   William W.; Dahl,   Bruce L.
Development of genetically modified crops is challenging the functions of the grain marketing system with many participants arguing for Identity Preservation systems prior to release of GM varieties.  In this study, a stochastic optimization model was developed to determine optimal testing strategies.  The model chooses the optimal testing strategy that maximizes utility (minimizes disutility) of additional system costs due to testing and rejection and allows estimation of the risk premium required for sellers to undertake a dual marketing system with GM/Non-GM segregations over the current Non-GM system.  Elements of costs (testing costs, rejection costs, and risk premium) were estimated for a base model representing a grain export chain.  The model...

COTTON CULTIVAR, PLANTING, IRRIGATING, AND HARVESTING DECISIONS UNDER RISK
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Larson,   James A.; Mapp,   Harry P., Jr.
Producers in southwest Oklahoma lack adequate information about optimal planting decisions for cotton. This study uses a cotton growth simulation model to evaluate alternative cultivar, planting date, irrigation, and harvest choices. Effects of using information about soil moisture at reproduction and revenue loss at harvest in making cultivar and planting data decisions are evaluated. Using soil temperature information to plant at an early date produced high net revenue some years, but reduced mean net revenue and increased risk. Producers maximizing expected net revenue should plant a short-season cultivar in late May and use soil moisture information to schedule irrigation at reproduction.

Cotton Farmers' Technical Efficiency: Stochastic and Nonstochastic Production Function Approaches
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chakraborty,   Kalyan; Misra,   Sukant K.; Johnson,   Phillip N.
Technical efficiency for cotton growers is examined using both stochastic (SFA) and nonstochastic (DEA) production function approaches. The empirical application uses farm-level data from four counties in west Texas. While efficiency scores for the individual farms differed between SFA and DEA, the mean efficiency scores are invariant of the method of estimation under the assumption of constant returns to scale. On average, irrigated farms are 80% and nonirrigated farms are 70% efficient. Findings show that in Texas, the irrigated farms, on average, could reduce their expenditures on other inputs by 10%, and the nonirrigated farms could reduce their expenditures on machinery and labor by 12% and 13%, respectively, while producing the same level of output.

Cotton Futures Dynamics: Structural Change, Index Traders and the Returns to Storage
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Power,   Gabriel J.; Robinson,   John R.C.
The commodity bull cycle of 2006-2008 and subsequent dramatic price decline have been a source of hardship for traditional commodity market participants such as producers and merchant/shippers. The usefulness of futures markets has been called into question, especially given that some market movements did not appear to be justified by economic fundamentals. An emerging research literature examines the possible influence of futures traders, and particularly the non-traditional Index Traders, on the well-functioning of futures markets and underlying commodity markets. Cotton is a relatively under-studied commodity that is of particular importance for producers in the South and Southwest. To this end, this paper asks the following questions: (1) What role...

Cotton in Zambia: 2007 Assessment of its Organization, Performance, Current Policy Initiatives, and Challenges for the Future
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is one unquestioned success of Zambia’s turn towards a market economy. After liberalization in late 1994, production rose from 20,000 mt to over 100,000 mt in the 1998 harvest year. After collapsing to less than 50,000 mt in 2000, it has risen steadily, nearing 200,000 mt in 2005. Over 2002-2005, exports of cotton lint were first among all agricultural exports in value, 30% higher than any other agricultural export (Export Board of Zambia 2006). The closest competitor to cotton during this time –raw cane sugar –is primarily produced on large operations, while cotton is almost entirely a smallholder crop. Its potential role in poverty alleviation and food security is, thus, very large. The success of this sector has been achieved despite persistent...

Autores: Farnsworth,   Richard L.; Moffitt,   L. Joe.
The risk flexible production model developed by Just and Pope is estimated for the case of cotton in California’s San Joaquin Valley and the implications of the model for factor demand are examined.   Results indicate risk-reducing roles for farm machinery, labor, and fertilizers in contrast to restrictions imposed by traditional stochastic production specifications.   Qualitative assessment of estimated risk effects on factor employment under risk aversion are evaluated by comparison to the risk-neutral solution.

Cotton is one of the most important smallholder cash crops in Sub-Saharan Africa (SSA).  How to ensure input supply, credit recovery and competition is a subject of intense policy debate.  This paper examines the performance of cotton sector development policies in Mozambique and Zambia.  Both countries face the challenge of organizing input supply to farmers in the absence of rural credit markets, and competing in international markets distorted by production subsidies in developed countries.  Both countries privatized cotton ginning in the 1990s.  Emerging from civil war, Mozambique established geographical monopolies to interlink input and output markets and facilitate credit recovery.  In Zambia, the government completely liberalized the cotton sector,...

Counterproductive Counternarcotic Strategies?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Andersson,   Camilla I.M.
We model the economic incentives surrounding opium crop production in Afghanistan. Specifically, we examine the impact of eradication policies when opium is used as a means of obtaining credit, and when the crops are produced in sharecropping arrangements. The analysis suggests that when perfect credit markets are available, an increased risk of eradication will lead to less land being allocated to opium poppy. However, when opium is used as a means of obtaining credit, the effects of eradication are no longer clear-cut. Finally, under sharecropping arrangements, increased risk of eradication will make the tenants worse off, while landlords may benefit.

Cow-Calf Producer Perceptions Regarding Individual Animal Traceability
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schulz,   Lee L.; Tonsor,   Glynn T.
This study provides valuable insights into cow-calf producer voluntary participation in the National Animal Identification System and producers’ perceptions of several issues critically impacting the success of voluntary traceability systems. Cow-calf producers believe that the most important issues to the U.S. beef industry in designing a national, individual animal traceability system are monitoring/managing disease, maintaining current foreign markets, accessing foreign markets, and increasing consumer confidence. Furthermore, producers are concerned with cost, liability, reliability of technology, failure of system to meet stated goals, and confidentiality of information associated with these systems.

Creating Carbon Offsets in Agriculture through No-Till Cultivation: A Meta-Analysis of Costs and Carbon Benefits
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Manley,   James G.; van Kooten,   G. Cornelis; Moeltner,   Klaus; Johnson,   Dale W.
Carbon terrestrial sinks are often seen as a low-cost alternative to fuel switching and reduced fossil fuel use for lowering atmospheric CO2. To determine whether this is true for agriculture, one meta-regression analysis (52 studies, 536 observations) examines the costs of switching from conventional tillage to no-till, while another (51 studies, 374 observations) compares carbon accumulation under the two practices. Costs per ton of carbon uptake are determined by combining the two results. The viability of agricultural carbon sinks is found to vary by region and crop, with no-till representing a low-cost option in some regions (costs of less than $10/tC), but a high-cost option in others (costs of $100-$400/tC). A particularly important finding is that...

This study analyzes the effect of the Loan Deficiency Payment (LDP) program, established under the Federal Agriculture Improvement Reform (FAIR) act of 1996, on corn and soybean basis pattern patterns in Missouri.  Additionally, spatial competition is incorporated into the basis models.  Using weekly corn and soybean basis pattern data from 1993 through 2001 for multiple locations in Missouri, and incorporating a variable for when the LDP is in effect, empirical models examining factors affecting corn and soybean basis pattern patterns are estimated.   Results indicate that the presence of the LDP program has a significant economic impact on soybean basis.  Furthermore, spatial competition strengthens corn basis.

Crop biodiversity repercussions of subsidized organic farming in Greece
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nastis,   Stefanos A.; Michailidis,   Anastasios; Mattas,   Konstadinos.
This paper analyzes the impact of CAP financial assistance on crop biodiversity under uncertainty. A stochastic production function is employed and estimated to assess whether risk-averse farmers hedge risk by diversifying their portfolio of crops, thus increasing crop biodiversity. The model is applied to farm-level data of organic crop farms in Greece. Organic farming financial assistance poses a double-edged sword: even though it is considered agrobiodiversity enhancing as a cultivation method, subsidizing it can become agrobiodiversity reducing, since farmers may select to cultivate only the subsidized crops. The study shows that risk aversion leads to crop biodiversity conservation. However, providing CAP financial assistance on certain crops appears...

Agriculturally, South Dakota is a unique state possessing the highest rate of adoption for genetically modified crop varieties.  In 2009 ninety-six percent of corn acres planted in South Dakota were genetically modified compared with eighty-five percent nationally (Economic Research Service).  Additionally, South Dakota has seen a dramatic increase in the number of acres treated with insecticide over the past 20 years.  These two situations taken together seem to be counterintuitive.  Some genetically modified varieties, such as Bt corn, are equipped with genetic defenses so that they can protect the plant from target pests.  Intuitively, one would expect to see a decrease in insecticide use as adoption of genetically modified varieties increase.  Recent...

CROP DIVERSITY AS THE DERIVED OUTCOME OF FARMERS' 'SURVIVAL FIRST' MOTIVES IN ETHIOPIA: WHAT ROLE FOR ON-FARM CONSERVATION OF SORGHUM GENETIC RESOURCES?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wale,   Edilegnaw; Virchow,   Detlef.
Crop genetic resources are the building blocks of sustainable agricultural development due to their relevance not only as inputs for variety development but also as indigenous crop insurance mechanisms through traditional variety portfolio management. Their continuous survival is, however, threatened by natural and human driven factors. This threat has induced the need for designing conservation measures. Among the in situ and ex situ conservation options available to conserve crop genetic resources, on-farm conservation has recently attracted enormous attention. To make this option operational, placing incentives (that link conservation with utilization) and removal of perverse incentives are believed to be crucial so that landraces of no immediate...

Crop genetic resource policy: the role of ex situ genebanks
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wright,   Brian D.
The world-wide capacity of genebanks for ex situ conservation of crop genetic resources has increased greatly since the 1970s, improving the access of crop breeders to landraces and wild and weedy relatives. But utilization of genebank resources has not kept pace. The set of popular cultivars in major crops is typically rather small, and their ancestry encompasses only a fraction of the genetic diversity currently available in other cultivars. Discussions of farmers' rights that focus on compensation for current incorporation of farmers' varieties in new cultivars have diverted attention from the question of why so little of the newly accessible genetic diversity is currently being utilized by public and private breeders. To optimize the future provision...

Crop genetic resources are the basis of agricultural production, and significant economic benefits have resulted from their conservation and use. However, crop genetic resources are largely public goods, so private incentives for genetic resource conservation may fall short of achieving public objectives. Within the U.S. germplasm system, certain crop collections lack sufficient diversity to reduce vulnerability to pests and diseases. Many such genetic resources lie outside the United States. This report examines the role of genetic resources, genetic diversity, and efforts to value genetic resources. The report also evaluates economic and institutional factors influencing the flow of genetic resources, including international agreements, and their...

Crop Insurance Purchase Decisions: A Study of Northern Illinois Farmers
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ginder,   Matthew G.; Spaulding,   Aslihan D.; Winter,   J. Randy; Tudor,   Kerry W.
When selecting crop insurance coverage, farmers must consider multiple factors. The importance associated with factors that are considered when making crop insurance decisions varies among individual farmers. As available crop insurance options increase, selecting the appropriate coverage becomes a more complicated process. The prevalence of crop insurance participation and the existence of multiple selection criteria also makes understanding participant decisions more difficult. This paper provides findings of a mail survey conducted among farmers in northern Illinois. Mainly, this paper examines factors influencing farmers’ crop insurance purchase decisions, types of coverage purchased, and farmers’ risk attitudes.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Talpaz,   Hovav; Mjelde,   James W.
A method for optimizing the irrigation schedule is presented. When the response surface, generated by “experimenting” with the crop simulation models is concave (convex), an optimal solution can be found. The process is iteratively repeated till convergence is achieved. Corn irrigation scheduling is demonstrated, with soil moisture levels as control variables.

Autores: Zbeetnoff,   Darrell M.; Jeffrey,   Scott R.
As part of the project entitled "Management Options for Grain Production in the 1980s and 1990s", a farmer survey was conducted during the fall and winter of 1988-89. A total of 234 Manitoba crop producers were interviewed, and asked questions concerning the information used and required in making specific crop management decisions. The survey respondents were asked questions pertaining to the following management decisions: 1. fertilizer rates, and method/timing of nitrogen application, ii. method/timing of pesticide application, 111. varietal selection for wheat and canola, and iv. canola acreage decisions. In each case, farmers were requested to provide actual practices, information used in making decisions, and perceived information gaps. Producers...

Crop Production Functions for Analysis of Global Change Impacts in Spain
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gomez,   Sonia Quiroga; Iglesias,   Ana.
The goal of this paper is to increase the capacity of the agriculture sector to understand and respond to the climate variability, by reducing the uncertainty of the farmers over decisions that are affected for meteorological conditions. To study the yield responses to meteorological variables in the past is crucial to understand the vulnerability of the agriculture to the climate change in the future. We have estimated regression models where the historical yields have been put in dependence of variables that can represent main drivers of global change, such as climate variables and technological ones. In this context we evaluate its influence over the yields. Among the conclusions we find that the adaptation to climate change requires challenges in which...

Crop Production Using Variable Rate Technology for P&amp;K in the United States Midwest: Evaluation of Profitability
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bolotova,   Yuliya.
This study evaluates profitability of crop production with variable rate technology (VRT) for P&amp;K application relative to profitability of crop production with uniform rate technology (URT) using data from six fields with a corn-soybeans rotation situated in Indiana. The results suggest that crop production using VRT is more profitable than using URT in one of the six fields. In the case of the other five fields profitability of crop production using VRT relative to using URT falls in the range of 85 to 92%. Under the assumption of lower costs for field diagnostic services and variable rate fertilizer application profitability of crop production using VRT increases.

Autores: Shaik,   Saleem; Coble,   Keith H.; Knight,   Thomas O.; Baquet,   Alan E.; Patrick,   George F.
A multinomial logit is utilized to model the choice of whether to purchase yield or revenue insurance using subjectively elicited survey data. Our results indicate that the demand for crop insurance is inelastic (-0.40), consistent with most earlier yield elasticity estimates, but the elasticity for choices between yield and revenue insurance is found to be relatively more elastic (-0.88).

CROP SUBSTITUTION ON UK SUGAR BEET FARMS AND ITS EFFECTS ON THE ENVIRONMENT: A MULTI-PRODUCT COST FUNCTION APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Renwick,   Alan W.; Revoredo-Giha,   Cesar.
This paper analyzes the effect that the imminent reform of the EU sugar beet regime will have on United Kingdom (UK) sugar beet farms. Specifically, we estimate a multi-product cost function to analyze the effect the changes on the sugar beet price support and quota will have on the crop allocation of sugar beet farms and their aggregate use of inputs. Based on these estimates we discuss the implications that changes in the crop patterns may have on farm environmental variables such as soil loss and groundwater pollution.

Crop Supply Response under Risk: Impacts of Emerging Issues on Southeastern U.S. Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Liang,   Yan; Miller,   J. Corey; Harri,   Ardian; Coble,   Keith H.
In this paper we consider factors that affect both crop prices and yields in order to examine supply responses of major crops in the Southeast. Due to the variable nature of crop production in the Southeast, previous studies that ignore price and yield risk may fail to capture one of the salient features of the region’s agriculture. Our results indicate supply elasticity values for corn, cotton, and soybeans of approximately 0.670, 0.506, and 0.195, respectively. Compared with the results of studies in other regions, corn and cotton acres respond more to price changes and soybean acres respond less to price changes.

CROP SUPPLY RESPONSES UNDER UNCERTAINTY IN TWO SENEGALESE REGIONS:  A COMPARATIVE STUDY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sidibe,   Mamadou.
Farm resource allocation decision, particularly in developing countries, is generally a risky process.  The uncertainty related to yields and farm product prices suggests that farmers behave in risk-averse ways.  This research uses linear programming models under a risk framework to investigate about cropping patterns and technologies most profitable to farmers in two Senegalese zones:  The Center of the Peanut Basin and the Upper Casamance.  Normative supply responses are derived for the two agricultural zones investigated under a food security perspective by making assumptions about farm price levels.  In the Central Peanut Basin, acreage under cultivation does not respond to price increases; supply responses have constant slopes.  In the Upper Casamance...

Crop switching as a strategy for adapting to climate change
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kurukulasuriya,   Pradeep; Mendelsohn,   Robert.
This paper examines the impact of climate change on primary crops grown in Africa. An innovative approach is presented that bridges the gap between agro-economic and traditional Ricardian models. We label it a ‘structural Ricardian model’. It first captures the type of crop a farmer will select and then examines the conditional net revenue of that crop. The model is estimated using a sample of over 5000 farmers across 11 countries in Africa. The analysis finds that farmers shift the crops they plant to match the climate they face. Studies that fail to account for crop switching will overestimate the damages from climate change and underestimate the benefits.

Crop Yield Skewness and the Normal Distribution
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hennessy,   David A.
Empirical studies point to negative crop yield skewness, but the literature provides few clear insights as to why. This paper formalizes three points on the matter. Statistical laws on aggregates do not imply a normal distribution. Whenever the weather-conditioned mean yield has diminishing marginal product with respect to a weather-conditioning index, then there is a disposition toward negative yield skewness. This is because high marginal product in bad weather stretches out the yield distribution's left tail relative to that for weather. For disaggregated yields, unconditional skewness is decomposed into weather-conditioned skewness plus two other terms and each is studied in turn.

Crop Yield Skewness under the Law of Minimum Technology
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hennessy,   David A.
A large empirical literature exists seeking to identify crop yield distributions. Consensus has not yet formed. This is in part because of data aggregation problems but also in part because no satisfactory motivation has been forwarded in favor of any distribution, including the normal. This article explores the foundations of crop yield distributions for the Law of the Minimum, or weakest-link, resource constraint technology. It is shown that heterogeneity in resource availabilities can increase expected yield. The role of stochastic dependence is studied for the technology. With independent, identical, uniform resource availability distributions the yield skew is positive, whereas it is negative whenever the distributions are normal. Simulations show how...

A myriad of policy issues and questions revolve around understanding the bioeconomy. To gain insight, we develop a stochastic and dynamic general equilibrium model and capture the uncertain nature of key variables such as crude oil prices and commodity yields. We also incorporate acreage limitations on key feedstocks such as corn, soybeans, and switchgrass. We make standard assumptions that investors are rational and engage in biofuel production only if returns exceed what they can expect to earn from alternative investments. The Energy Independence and Security Act of 2007 mandates the use of 36 billion gallons of biofuels by 2022, with significant requirements for cellulosic biofuel and biodiesel production.

Autores: Skarzynska,   Aldona.
This study shows the impact of cropping intensity on the economic results of plant production in Poland. The real amount of production outlays, which in value terms represents the level of direct costs, was adopted as the intensity measure. The economic results diversification scale is reflected by the level of gross margin and income from management activity, as well as by the production profitability index in the activity types analysed. When using low-intensity, as compared to high-intensity, cropping technologies, the economic results of the activities in question become more favourable. The profitability analysis of various production factors points to a prevalence of agricultural farms with low intensity levels of the activity conducted. Lower...

Cropping Structures Adjustments Under Water Limitations in the Egyptian Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Abdou,   Amin I.
Using programming methods, the two models of cropping structures suggested by the study were remarkably different. The first model considered water availability levels, while the second tried to optimize its use. As such, some cash crops were excluded from the second model as water extensive users, such as some kinds of fruits. Hence, the second type models expected net revenues and benefit-cost ratios dropped to nearly one-third the corresponding estimates of the first type, and about 10-20% higher than those of the actual cropping structures in average. Accordingly, encouraging farmers to adopt cropping patterns of rational water use would be in vain unless fortified by taxation tools and guidance toward efficient methods of cost reduction and/or yields...

Cross-Commodity Analysis of China's Grain Sector: Sources of Growth and Supply Response
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Colby,   Hunter; Diao,   Xinshen; Somwaru,   Agapi.
We investigate sources of output growth and supply response in rice, wheat, corn, and soybeans, the four most important crops in China's grain sector, during 1978-97. Using a growth accounting methodology, we found large total factor productivity (TFP) contributions to growth in grain production immediately following China's rural economic reform (1978-85). In 1995-97, the TFP contribution dropped to only 16 percent of growth in grain production, as greater use of inputs increasingly drove growth. In the supply response analysis, the results of the econometrically estimated restricted profit function confirm a joint and nonseparable multiproduct technology for China's grain sector. Complementarity prevails in the grain sector among different outputs and...

During 2006 the fishmeal price nearly doubled from $500MT to over $900MT. The objective of this research is to determine the optimal cross-hedge ratio between fishmeal and soybean meal and corn, and corresponding hedging weight between corn and soybean. Results indicate all hedging weight should be placed on the corn futures contract. This is an interesting result since prior fishmeal cross-hedging research has not analyzed the corn futures contract as a risk management mechanism.

Global trends nowadays towards long term sustainable crop production is hinged on either supplementing the use of chemical fertilizers with organic materials or a complete use of organic materials. This is more so since substituting chemical fertilizers with organic materials reduces the risks of exposure to ailments that arise on account of synthetic compounds and increases farmers’ gains via reduced soil erosion and carbon emissions and increased bio-diversity. In this vein, the current study investigated organic materials use in Nigeria’s agriculture. Specifically, the study examined availability and use of chemical fertilizer and organic materials substitutes and investigated factors affecting the use of organic materials in the Nigerian food sector....

Sugarcane farmers in many districts are considering on-farm water storages (OFWS’s) as a means of countering ongoing water shortages. OFWS’s are attractive because they can be used to capture runoff and tailwater, and for the temporary storage of surplus water from other irrigation sources (eg allocation, out of allocation, water harvesting etc), thereby providing increased flexibility in managing limited water supplies. The decision to invest in such storages is, however, complex and multi-facetted, requiring assessment of a range of biophysical, economic, legislative and social factors. Computer-based simulation models can potentially capture many of these factors and their interactions, and hence, can play a useful decision support role. In this paper,...

The 2006 – 2007 agricultural campaign was characterized by a good rainfall. As a result, cereal production has increased according to the survey conducted by CPS/DNSI.. The prices of cereals reflect this increase in production. To keep producers from selling their products at lower prices, it is recommended to constitute the national food security stock and cereal banks at commune level in December 2006, lift measures forbidding the exports of cereals, and put in place overdraft facilities for producers and traders for cereals storage.

Decaffeinated? Situation, Trends, and Prospects for Smallholder Coffee Production in Rwanda
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Loveridge,   Scott; Nyarwaya,   Jean Baptiste; Shingiro,   Emmanuel.
Most Rwandan coffee is currently grown and processed the same way it was a decade ago.  Consequently, Rwanda’s coffee production and marketing system has not been able to keep up with  changes in the global market for high quality coffee. Given world market gluts of relatively poor quality coffee, Rwanda is now exporting a product that fetches low prices. Despite the challenges in coffee marketing and production, coffee remains one of Rwanda’s most important official sources of foreign exchange and the drop in production is of major concern to both the public and private sectors. In an effort to assist decision makers in the coffee sector better understand factors affecting farmers’ production decisions and their attitudes about coffee, the FSRP fielded a...

Autores: Dhehibi,   Boubaker; Lachaal,   Lassaad; Karray,   B.; Chebil,   Ali.
The aim of this paper is to investigate the relative contribution of technical efficiency, technological change and increased input use to the output growth of the Tunisian olive oil growing farms using a stochastic frontier production function approach applied to panel data for the period 1995- 1997. The proposed methodology is based on the use of a flexible translog functional form. Results indicate that technical efficiency of production in the sample of olive producing farms investigated ranges from a minimum of 24.8% to a maximum of 84.6% with an average technical efficiency estimate of 48.5%. This suggests that olive producers may increase their production by as much as 51.5% through more efficient use of production inputs. Further, the production is...

Defining and Characterizing Approaches to Farm Management
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McBride,   William D.; Johnson,   James D.
Exploratory factor analysis was used to identify approaches to farm management based on a list of management questions posed to a sample of U.S. cash-grain farmers.  Three approaches were identified by the factor analysis:  price negotiation, long-term cost control, and input adjustment.  Estimated factor scores regressed against farm and operator characteristics indicate a profile of producers using each approach that is closely related to stage-of-life of the farm operator and farm business.  In addition to operator age and planning horizon, operator risk preference and farm organization and location were other important determinants of the approach to management.

Defining the Costs of an Outbreak of Karnal Bunt of Wheat
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brennan,   John P.; Thorne,   Fiona S.; Kelly,   Paul W.; Murray,   Gordon M.
In determining the economic impact of a possible outbreak of the quarantinable wheat disease Karnal Bunt, an examination was made of the detailed components of the costs involved. The costs were classified as: (a) Direct costs (yield and quality losses); (b) Reaction costs (export bans, quality down-grading, seed industry costs); and (c) Control costs (quarantine zones, fungicides, spore destruction). The relative importance of each of these cost components is measured for a hypothetical outbreak of Karnal Bunt in the European Union, as a means of ensuring that the policy responses to such an outbreak are appropriate considering the costs involved.

Delivering Seeds of 'Orphan' Crops: The Case Studies of Potato and Groundnut in India
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pal,   Suresh; Singh,   Harbir; Mathur,   Prasoon.
This paper examines the performance of the Indian seed system in the context of high volume, low value seed, using the case studies of potato and groundnut. In theory, public sector should be able to address seed needs of farmers growing these crops. However, the ability of the public sector is constrained by a number of institutional and technical factors, and farmers largely depend upon traditional sources of seed. The traditional sources meet more than two-thirds of the total seed demand , and the rest is met by the formal seed system, mainly public seed agencies. Most of the farmers buy fresh seed for quality reasons, and only 12-15 percent farmers purchase seed to change variety. In potato, technological innovation provided options to enhance...

DEMAND AND SUPPLY ANALYSIS OF CORN IN INDONESIA FROM 1970-1988
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ali,   Mohamad Rum.
Corn is the second most important food crop in Indonesia.  Harvested area has fluctuated around an average of 2.7 million hectares between 1970-1988.  This is roughly one third of the area devoted to rice and twice that of cassava. Production is almost entirely a smallholder activity, which provides income and staple food for over 10 million farm households who rarely farm more than 2 hectares of land. Corn production in Indonesia is concentrated on Java and Madura, which account for almost 75 percent of production.  On Java and Madura, almost all corn is produced on the eastern half of the land area.  The province of East Java produces 45 percent of the nation's total output. The land types used for corn production are "tegalan" (rain-fed) and "sawah"...

Demand and supply factors in the export of South African fresh oranges to the United Kingdom: 1976-1993
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Khuele,   P.R.S.; Darroch,   Mark A.G.
Two Stage Least Squares and principal component analysis were used to estimate the export demand and supply of South African (SA) fresh oranges in the United Kingdom (UK) during 1976-1993. Export demand was negatively related to the SA fresh orange price relative to the price of fresh oranges from Israel, and positively related to lagged orange exports (consumer brand loyalty proxy). Export supply was positively related to lagged net export realisation price relative to domestic orange price, the SA fresh orange price in the UK relative to the SA fresh orange price in France, lagged exports (export orientation), and supply shocks. The relative price elasticity of export demand was inelastic in both the short- and long-run, indicating that Capespan...

Demand and Supply of Crop Infraspecific Diversity on Farms: Towards a Policy Framework for On-Farm Conservation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bellon,   Mauricio R.
Interest is increasing worldwide in on-farm conservation as a component of a strategy to conserve crop genetic resources. On-farm conservation may require outside support to small-scale farmers in areas of crop domestication and diversity. This paper argues that crop infraspecific diversity maintained by farming households in these areas results from the interplay between demand and supply for this diversity (i.e., its loss may be demand- or supply-related). In the first instance, interventions should be aimed at increasing the value of crop diversity for farmers or decreasing the farm-level opportunity costs of maintaining diversity. In the second instance, interventions should decrease the transaction costs of accessing crop diversity. It may be...

Demand for Drought Tolerance in Africa: Selection of Drought Tolerant Maize Seed using Framed Field Experiments
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dalton,   Timothy J.; Yesuf,   Mahmud; Muhammad,   Lutta.
Recent projections on the impact of climate change argue that eastern and southern Africa will be two regions around the globe that will experience dramatic reductions in maize yields by mid‐century. Absent from these projections is any consideration for farmer adaptation of cropping practices or land reallocation. This research quantifies risk, loss and ambiguity aversion for a sample of smallholder Kenyan farmers using framed field experiments. This behavioral information, directly elicited, is used to condition the selection of maize varieties differentiated by drought tolerance, pest resistance, maturity, and seed price. Overall, the willingness to pay for drought tolerance and other attributes is highly heterogeneous as determined through a Latent...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wohlgenant,   Michael K.; Rezitis,   Anthony N.; Safley,   Charles D.
Analysis of demand for pansies and mums sold in independent garden centers indicates that price and age are important factors influencing demand.  In the fall of 1996, data were collected from a survey of independent garden centers in North Carolina. Statistical analysis was conducted by estimating the relationship between consumer expenditure shares of pansies and mums and prices paid per plants, household income, and various demographic and product characteristic variables.  The models were estimated by the least-squares method with correction for selectivity bias, resulting from zero purchases.  Own-price elasticities of demand for pansies and mums of –0.80 and –0.76, respectively, were estimated.  The results also indicate that older customers who live...

DEMAND FOR HERBICIDE IN CORN: AN ENTROPY APPROACH USING MICRO-LEVEL DATA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Arndt,   Channing.
Price responsiveness of herbicide demand in corn for farmers in Indiana'’s White River Basin using cross-section data from individual farms is estimated. Particular attention is paid to appropriate treatment of binding nonnegativity constraints. Estimation was first attempted using an approach to demand systems estimation suggested by Lee and Pitt. However, analytical and computational difficulties effectively preclude estimation by the Lee and Pitt approach. As an alternative, a maximum entropy (ME) approach is presented and discussed. Results from the ME estimator tentatively indicate limited response of herbicide demand to changes in own prices. The maximum entropy approach to demand systems estimation appears to have merit and warrants further attention.

Demand for High-value Secondary Crops in Developing Countries: The Case of Potatoes in Bangladesh and Pakistan
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bouis,   Howarth E.; Scott,   Gregory.
Secondary crops are of increasing interest to policymakers and planners in developing countries because of a desire to diversify economic activities and because of their proven potential to raise farm incomes and rural employment. To assess this potential, basic information on the demand characteristics for these crops is required. But, given the large number of possible crops to be studied, policy analysts require an estimation procedure that is less data-intensive and time-intensive than standard econometric estimation procedures. In this paper, a relatively new, low-cost procedure, based on demand for food characteristics, is applied, illustrating its usefulness for analysis of demand for potatoes in Bangladesh and Pakistan. In Asia, the potato should...

Demand for Irrigation Water for Pistachio Production from Depleting Groundwater Resources: Spatial Econometric Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jaghdani,   Tinoush Jamali; Brümmer,   Bernhard.
Depletion of groundwater resources is an international problem, and groundwater is probably the world’s most extracted raw material. The agriculture sector is one of the biggest users of groundwater resources for irrigation activities, and it plays an important role in the depletion of these resources. The estimation of demand function for groundwater resources is the first step toward any policy recommendation in this field of research. However, only scarce attention has been given to empirical studies of the demand structure of groundwater resources by the help of econometrics and considering the quality of the resources in the context of a single aquifer. Therefore, an empirical estimation of the demand function for individual users which considers...

When obtaining nitrogen (N), phosphate (P) and potash (K), purchasing decisions concerning the quantity and the form of each plant nutrient must be made.  Logit models are estimated for the choice-of-form decision by considering those variables influencing the probability that plant nutrients will be purchased in Tennessee as part of a mixed fertilizer or as direct application materials.  Parameter and elasticity estimates can be used by fertilizer manufacturers and distributors to anticipate changes in the composition of demand for plant nutrients in Tennessee.

In this paper, we derive estimates for willingness to pay for rainfall-index based insurance contracts. Surveys were undertaken in four regions in Morocco, representing different mean and variability of rainfall conditions. Results indicate that respondents in the high variability regions preferred contracts that paid out more often (had higher rainfall trigger levels), and which were more costly. In fact, a strong majority of respondents indicated they would purchase these contracts at the fair-value price; the estimated median willingness to pay for such contracts was between 12-20 percent above the fair value contract. However, in the lower rainfall variability regions, the cheaper contracts with lower trigger values were the only contracts for which...

Autores: van Schalkwyk,   Hendrik P.
In this study demand relations for primary oilseeds in South Africa is estimated and interpreted with the use of econometric models. Two different models, namely the Linear Approximate Almost Ideal Demand System (LA/AIDS) and the two-step Error Correction Model (ECM), were applied to annual oilseed data for the years 1971-2002.  The F ratio test for separability failed to reject the null hypothesis of weak separability in most cases, indicating that sunflower seed, soybeans, groundnuts and cotton could be included in the same system and modeled together.  The Hausman test for exogeneity was conducted and proved that the expenditure variable included in the estimated equations is indeed exogenous. The exogeneity of the expenditure variable provides...

DEMAND, SUPPLY AND PRICE PREDICTION OF RICE IN TAIWAN FROM 1976 TO 1985
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lee,   Wun-Chi.
Taiwan is located in the subtropical area of the Far East.  With the benefit of suitable weather, average temperature just under 71 F in the north and nearly 76 F in the south, and with the yearly precipitation around 75 inches, rice has been the self sufficient staff crop in Taiwan.  Even in the early eighteenth century, Taiwan exported rice to support the supply in Mainland China.  Rice is a necessity for Taiwanese.  A sufficient supply and stabilization of its price are relevant to the whole economy and society.  Because of the development of industry and economic growth, a lot of cultivated land has been transferred from rice production to industrial or architectural utilization under the principle of comparative advantage since 1958.

Demographic and Management Factors Affecting the Perceived Benefit of Winter Cover Crops in the Southeast
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bergtold,   Jason S.; Duffy,   Patricia A.; Hite,   Diane; Raper,   Randy L.
The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. Farmers will adopt and continue to utilize cover crops in their production systems as long as the perceived benefit of using cover crops (e.g. increased yield, higher profits, and improved soil productivity) is positive.  The perceived benefits, while partially based on actual changes, may be influenced by demographic, economic and management factors. The purpose of this paper is to examine the demographic and management factors affecting the perceived benefit, in terms of improved crop yield, of using winter annual cover crops. A tobit model is estimated using survey data of Alabama farmers examining cover crop use and management. The model examines the...

Deregulation of Lesotho's maize market
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: van Schalkwyk,   Herman D.; van Zyl,   Johan; Botha,   P.W.; Bayley,   B.
During the past year, there have been major policy reforms in Lesotho and South Africa with respect to maize pricing and marketing. In Lesotho the impact of deregulation on producers, consumers and government revenues was substantially lower than it should have been, and as a result Lesotho was not able to reap the full benefits of these changes. This is partly because information on the changes to the maize marketing system did not reach the potential beneficiaries of the new system. Free and easily accessible information is an essential element of a free market system. SACU countries must ensure the availability of information if they want to compete internationally.

Deregulation of the Maize Marketing System of Swaziland and Implications for Food Security
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mashinini,   Nkosazana N.; Obi,   Ajuruchukwu; van Schalkwyk,   Herman D.
Recent shortfalls in the supply of maize in the Kingdom of Swaziland have exacerbated the country's growing food insecurity and led to fresh calls for full deregulation of the maize marketing system. The proponents of deregulation believe that it eliminates inefficient production and service units by transferring resources to their best alternative uses. While the theoretical foundations for that position are not questionable, no studies have to date explicitly investigated the effects of the current arrangements and the potential effects of full deregulation. This paper reports on a study that examined the welfare effects of the regulation of the country's maize industry and considered the likely impacts of full deregulation of the industry. Using a...

DERIVED DEMAND FOR WHEAT BY CLASS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Terry,   Justin J.; Marsh,   Thomas L.
To quantify price responsiveness and economic substitutability among wheat classes, derived demand functions were specified from a normalized quadratic profit function. Own-price and cross-price elasticities were estimated for hard red winter, hard red spring, soft wheat (combined red and white), and durum wheat. In general, soft wheat varieties were less responsive to their own price than were hard wheat varieties. Cross-price elasticities indicate that hard red winter wheat, hard red spring wheat, and soft wheat varieties are economic substitutes. Cross-price elasticities are different from those previously reported, which can have important policy implications.

Desarrollando mercados rurales: el rol de la incertidumbre y la restricción crediticia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Escobal D'Angelo,   Javier.
El estudio evalúa cuáles son los factores más relevantes para que un pequeño productor agrícola demande asistencia técnica con el propósito de incursionar en mercados “dinámicos”; es decir, en mercados que puedan absorber cantidades crecientes de su cultivo. Los resultados muestran que existe un segmento de productores cuya “distancia” a estos mercados no es tan significativa como para que no puedan incursionar en ellos. Sin embargo, restricciones asociadas al grado de organización de los productores, a su percepción del riesgo y a las posibilidades de acceso al mercado de crédito les impiden acceder a los beneficios adicionales que estos mercados ofrecen.

This paper, supported on the theory of the Boarding of the Elasticities, had as objective to show the influence of the exchange rate depreciation in the value of the Brazilian exportations. For this purpose, Structural Vector Autoregressive Models (SVAR Models) where used to calculate the offer of foreign currency elasticities, determining if depreciations in the currency would increase or reduce the exported value of soybean. The results showed that cambial depreciations really raise the value of the Brazilian exportations. The impulse response functions show that the exportation price is the variable that exerted greater influence in the exported value, indicating, perhaps, that politics that degenerate the Brazilian soybean exportations can contribute...

This paper investigates the determinants of farm households‟ participation in export cropping and the impact of export cropping on household welfare, using cross-sectional data obtained from the Ghanaian living standards survey 2005-6. Given the problem of selectivity bias that arise when households self-select into export cropping, we employ the full information maximum likelihood approach to analyze the participation decision, and generalized propensity matching approach to examine the welfare impacts of participation. The empirical results indicate that farmers facing lower transport costs and having better access to credit facilities are more likely to participate in export cropping. Estimates of the welfare impacts of export cropping generally reveal...

Determinants for Use of Certified Maize Seed and the Relative Importance of Transaction Costs
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bernard,   Munyua; Hellin,   Jonathan; Nyikal,   Rose Adhiambo; Mburu,   John G.
The rising world prices for major tradable staples such as maize have been a concern for sub- Saharan countries such as Kenya which are maize deficit countries. Maize is a major staple food for over 80 percent of Kenya’s population. Kenya relies on maize for up to 40 percent of its dietary energy supply and is accordingly searching for ways to increase maize productivity. Maize productivity has been rising in the last decade manly as a result of the use of improved germplasm and fertilizer. However, the proportion of farmers using these technologies is low and the aggregate productivity in maize is low compared to other countries and its potential. Previous studies on input adoption have often assumed the existence of perfect supply and product markets,...

As part of a major effort to address soil fertility decline in West Africa, a project on Balanced Nutrient Management Systems (BNMS) has since 2000 been implemented in the northern Guinea savanna (NGS) of Nigeria. The project has tested and promoted two major technology packages, including a combined application of inorganic fertilizer and manure (BNMS-manure) and a soybean/maize rotation practice referred to as BNMS-rotation.  This study employed Tobit model to examine factors that influence the adoption and intensity of utilization of BNMS technologies in the NGS of Nigeria. Results showed that less than 10% of the sample households adopted at least one of the two components of the technology package by the end of 2002.  However, by 2005 the adoption of...

This study employed a Tobit model to examine factors that influence the adoption and intensity of utilisation of improved maize varieties in the West Shoa Zone in the central highlands of Ethiopia. The estimated results indicate that level of education, household labour, farm size, extension services, farm income, and timely availability of improved maize seeds significantly influence the adoption and intensity of use of improved maize. It also showed that the impact of off-farm income and age of the household head on adoption and intensity of use of improved maize seed was insignificant.

Autores: Simtowe,   Franklin; Asfaw,   Solomon; Diagne,   Aliou; Shiferaw,   Bekele A.
This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the...

Determinants of Anomalous Prevented Planting Claims: Theory and Evidence from Crop Insurance
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rejesus,   Roderick M.; Lovell,   Ashley C.; Little,   Bertis B.; Cross,   Mike H.
This study examines the factors that determine the likelihood of submitting a potentially fraudulent prevented planting claim. A theoretical model is developed and the theoretical predictions are empirically verified by utilizing a binary choice model and crop insurance data from the southern United States. The empirical results show that insured producers with higher prevented planting coverage, lower dollar value of expected yield, and a history of submitting prevented planting claims are more likely to submit an anomalous prevented planting claim. The empirical model also suggests revenue insurance plans may be more vulnerable to prevented planting fraud than the traditional yield-based insurance plan. Results of this study can be valuable to compliance...

On farm conservation of crop diversity poses obvious policy challenges in terms of the design of appropriate incentive mechanisms and possible trade-offs between conservation and productivity. This paper compares factors explaining the inter-specific diversity (diversity among species) and infra-specific diversity (diversity among varieties within a species) of cereal crops grown in communities and on individual farms in the northern Ethiopian highlands.  Using named varieties and ecological indices of spatial diversity (richness, evenness, and inverse dominance), we find that a combination of factors related to the agro-ecology of a community, its access to markets, and the characteristics of its households and farms significantly affect both the inter-...

Determinants of farmers’ compliance with coffee eco-certification standards in Mt. Kenya region
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kirumba,   E.G.; Pinard,   F.
This paper sought to investigate determinants of farmers’ compliance with coffee eco-certification standards in Mt. Kenya region. Socio-economic, institutional and farm factors were analyzed and the binary logistic regression model was used to predict factors enhancing compliance. The findings show that perception of benefits, coffee as the main source of income, annual coffee production, and the number of times a farmer sprayed annually; were the main drivers of compliance. The findings point towards a growing concern that certification projects focus on ‘progressive’ farmers rather than seek to uplift and integrate ‘weak’ farmers. This calls for concerted efforts among all key stakeholders to enhance inclusivity and participation.

Determinants of Household Contributions to Collective Irrigation Management: A Case of the Doho Rice Scheme in Uganda
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nakano,   Yuko; Otsuka,   Keijiro.
In order to explore the conditions of successful irrigation management, this study investigates the determinants of household contributions to the cleaning of irrigation channels and the availability of water. By using primary data collected in an irrigation scheme in Uganda, we find that household contributions to the cleaning of irrigation channels are determined by the scarcity of irrigation water, opportunity cost of labor, and private benefit associated with plot size. We also find that the availability of irrigation water increases in the tertiary irrigation area where the coefficient of variation of plot size is large.

Determinants of Improved Maize Seed and Fertilizer Use in Kenya: Policy Implications
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ouma,   James Okuro; De Groote,   Hugo; Owuor,   George.
Maize is a key food crop in Kenya. While maize yields increased from 1.25 t ha-1 in early 1960s to over 2 tonnes in 1982, they fell below 1.5 t ha-1 in 2000. Given the limited land area, there is no doubt that Kenya will have to rely more on modern technologies for increased yields .Use of improved maize varieties and fertilizers will therefore continue to be critical inputs for improving productivity. To improve production, it is important to understand factors determining adoption and intensity of use of modern technologies. A stratified 2-stage sampling design was used to select 1800 households, subsequently interviewed by means of structured questionnaire. Econometric models were used to explore factors influencing adoption and intensity of use of the...

Determinants of Profit Efficiency Among Small Scale Rice Farmers in Nigeria: A Profit Function Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kolawole,   Ogundari.
This study employs a stochastic frontier approach to examine profit efficiency of small scale rice farmers in Nigeria using farm-level survey data collected from 200 farmers in the study area. Data were analysed using descriptive statistics and standard profit function. The result shows that about 60 percent of potential profit is gain due to production efficiency while the remaining can be attributed to both technical and allocative inefficiencies in the study area. Also, the result further revealed that age, educational level, farming experience and household size positively affected profit efficiency. These variables are thus important in policy formulation by government.

Crop genetic resources are the building block of sustainable agricultural development as these can be used to develop crop varieties adaptable to heterogeneous environmental conditions. Nepal is considered the center of origin and diversity for Asian rice, which still has many landraces. However, there has been continuous loss of genetic diversity and concern over it has grown in recent years. The main objective of this paper is to identify the determinants of variety diversity on-farm in the rainfed ecosystem of Nepal by using two-limit Tobit procedure. The diversity on farm appeared to be quite high evaluated based on the number of named varieties grown by the farmers. Majority of the farmers cultivated both modern varieties and landraces simultaneously...

Determinants of the Speed of Adoption of Soil Fertility-Enhancing Technologies in Western Kenya
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Odendo,   Martins; Obare,   Gideon A.; Salasya,   Beatrice.
Most adoption studies have employed cross-sectional data in a static discrete choice modelling framework to analyze why some farmers adopt at a certain point in time. The static approach does not consider the dynamic environment in which the adoption decision is made and thus does not incorporate the speed of adoption and the effect of time-dependent elements in explaining adoption. The adoption speed of an innovation is important in various aspects. Based on data from a survey of a random sample of 331 smallholder households in western Kenya, this study investigated determinants of time to adoption of mineral fertilizer, animal manure and compost using Duration analysis. Results revealed that factors that influenced timing of the adoption varied by the...

Autores: Jayasinghe,   Sampath; Beghin,   John C.; Moschini,   GianCarlo.
The United States is a large net exporter of corn seeds. Seed trade, including corn, has been expanding but its determinants are not well understood. This paper econometrically investigates the determinants of world demand for U.S. corn seeds with a detailed analysis of trade costs impeding exports flows to various markets. Trade costs include costs associated with distance, tariffs, and sanitary-phytosanitary (SPS) regulations imposed by foreign countries on U.S. corn seed exports. SPS policy information comes from the Excerpt data base of USDA-APHIS. The analysis relies on a gravity-like model based on an explicit specification of derived demand for seed by foreign corn producers. A SPS count variable is incorporated as a shifter in the unit cost of...

This paper econometrically investigates the determinants of world demand for U.S. corn seeds with a detailed analysis of trade costs impeding export flows to various markets, including costs associated with distance, tariffs, and sanitary and phytosanitary (SPS) regulations. The analysis relies on a gravity-like model based on an explicit specification of derived demand for seed by foreign corn producers, estimated based on data from 48 countries and for the years 1989 to 2004. An SPS count variable is incorporated as a shifter in the unit cost of seeds faced by foreign users. A sample selection...

Determination of yield and erosion damage functions using subjectively elicited data: application to smallholder tea in Sri Lanka
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ananda,   Jayanath; Herath,   Gamini; Chisholm,   Anthony H.
Tea has been Sri Lanka’s major export earner for several decades. However, soil erosion on tea‐producing land has had considerable on‐site and off‐site effects. This study quantifies soil erosion impacts for smallholder tea farms in Sri Lanka by estimating a yield damage function and an erosion damage function using a subjective elicitation technique. The Mitscherlich‐Spillman type of function was found to yield acceptable results. The study indicates that high rates of soil erosion require earlier adoption of soil conservation measures than do low rates of erosion. Sensitivity analysis shows the optimum year to change to a conservation practice is very sensitive to the discount rate but less sensitive to the cost of production and price of tea.

DETERMINING OPTIMAL FERTILIZATION RATES UNDER VARIABLE WEATHER CONDITIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Talpaz,   Hovav; Taylor,   C. Robert.
This paper presents a theoretical framework for incorporating the following sources of risk into the determination of optimal fertilization rates: (a) the influence of weather and other stochastic factors on the marginal product of fertilizer, and (b) uncertainty about the coefficients of the response function. The decision criterion considered is the maximization of profit subject to a risk constraint on the probability of not recovering the cost of the fertilizer. The theoretical framework is applied to the fertilization of dryland grain sorghum in the Texas Blacklands. Results indicate that the risk averse producer should substantially lower his fertilization rate if soil moisture at fertilization time is low.

Determining Optimal Levels of Nitrogen Fertilizer Using Random Parameter Models
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tumusiime,   Emmanuel; Brorsen,   B. Wade; Biermacher,   Jon T.; Mosali,   Jagadeesh; Johnson,   Jim; Locke,   James.
The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nonstochastic or ‘limited’ stochastic. In this study, we estimate rye-ryegrass yield functions where all parameters are random. Optimal nitrogen rates are calculated for two yield response functions: linear response plateau and quadratic. Nonstochastic models are rejected in favor of stochastic parameter models. However, the economic benefits of using fully stochastic models are small since optimal nitrogen rates do not differ greatly between stochastic and nonstochastic models.

DETERMINING SOCIALLY OPTIMAL NITROGEN APPLICATION RATES USING A DELAYED RESPONSE MODEL: THE CASE OF IRRIGATED CORN IN WESTERN KANSAS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nkonya,   Ephraim M.; Featherstone,   Allen M.
A delayed response model was used to examine the optimal nitrogen application for irrigated corn in western Kansas. Results show that taking into account the effect of leached nitrate on groundwater pollution reduces the profit-based nitrogen recommendation by 12.5% with a consequent reduction of the static profit of 6.7%.

DETERMINING SOCIALLY OPTIMAL NITROGEN APPLICATION RATES USING A DELAYED RESPONSE MODEL:  THE CASE OF IRRIGATED CORN IN WESTERN KANSAS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nkonya,   Ephraim M.; Featherstone,   Allen M.
Nitrate contamination of groundwater is an important problem. The transport of leached nitrate from the root zone to groundwater takes approximately 30 to 60 years. Many previous studies ignore this time lag by assuming instantaneous contamination. This analysis applies a delayed response model to account for the time lag between nitrogen fertilizer applications to the time the leached nitrate reaches groundwater. Results show that accounting for the leached nitrate externality reduces the nitrogen application rate by 13% and the returns above variable costs by 8% for farmers who apply both nitrogen and phosphorus. For farmers who do not use phosphorus, nitrogen use is reduced by 14% and the returns above variable costs by 22%. The application of...

Deciding how to coordinate activities can be a challenge posed in any marketing chain. This case involves an agricultural cooperative that has focused entirely on marketing raw sugar cane for additional refinement. Recent dramatic shifts in the sector have caused the members of the cooperative to consider building a facility that will process the raw sugar cane. In so doing, the cooperative can consider using the spot market, using contracts, vertically coordinating, or vertically integrating. This case study of Louisiana Sugar Cane Products, Inc. is a unique, real-life case that can be widely used in marketing and cooperatives courses.

The rice stink bug is a major pest of rice in Texas, causing quality related damage.  The previous threshold used for assisting in rice stink bug spray decisions lacked flexibility in economic and production decision variables and neglected the dynamics of the pest population.  Using stochastic dynamic programming, flexible economic thresholds for the rice stink bug were generated.  The new thresholds offer several advantages over the old, static thresholds, including increased net returns, incorporation of pest dynamics, user flexibility, ease of implementation, and a systematic process for updating.

The transition out of extreme poverty and hunger in agrarian economies requires an understanding of how new agricultural technologies are adopted by poor farmers. In Uganda, improved germplasm from the cassava breeding program has generated new varieties that are increasingly being grown by farmers. Although considerable success has been achieved in adoption of these varieties in general, there is increasing pressure on breeding and technology dissemination programs to improve the targeting of their efforts. This paper identifies the specific cassava varieties adopted thus far and their desirable and undesirable attributes. In addition, it determines the adoption rates of these varieties and the factors that have influenced the speed of adoption of the...

Autores: Ludena,   Carlos E.; McNamara,   Kevin T.; Hammer,   P. Allen; Foster,   Kenneth A.
Increased domestic concentration and international competition in the floricultural industry are forcing growers to improve resource management efficiency. Cost management and cost accounting methods are becoming key tools as growers attempt to reduce costs. These tools allow growers to allocate costs for each crop, increasing their greenhouse planning abilities. Growers have a relative high degree of risk due to potential crop and market failure. Individual growers have different tolerance for risk and risk bearing capacity. Growers need a cost accounting system that incorporates production and market risk, a system that allows them to make informed business decisions. The research reported in this paper developed a greenhouse budgeting model that...

The study used programming methods to assess the farm-level impact of incorporating forages, including dual purpose Cajanus cajan (C. cajan), into the crop-livestock system in the Coastal Savannah Zone of Ghana. The system was modeled in GAMS and solved using linear programming. The optimal enterprise mixes and their resultant net revenues with and without the interventions and therefore the change in net revenue were obtained. The intervention was to grow forages as part of the crop-livestock system and feed them to milking cows and their calves for increased milk production and growth. The grain of the forage was used as food by the farmers, and manure from the animals was also used for crop production. The effect of policy options like educating farmers...

The debate about the "quasi" moratorium on the release of GMOs in the European Union is on going. One of the major arguments that were put forward to delay the release of new traits was the one for more information. In this contribution we compare the situation for Bt-maize from the 1995 and 2004 perspective. The 2004 perspective differentiate between two scenarios: one without the CAP reform and one including the CAP reform. For the comparison we use an ex-ante assessment model based on real option theory that explicitly considers the irreversible costs and benefits of the technology. As empirical information about possible irreversible costs is scarce we identify the maximum incremental social tolerable irreversible costs, MISTICs, for Bt-maize, a...

Differences in Canadian and U.S. Farm Structure: What the Canadian Farm Typology Shows
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hoppe,   Robert A.; Niekamp,   Deborah; Banker,   David E.; Nakagawa,   Ken.
Canadian and U.S. farms vary widely in size and other characteristics, ranging from very small retirement and residential farms to firms with sales in the millions. Agriculture and Agri-Food Canada (AAFC) and the United States Department of Agriculture’s (USDA’s) Economic Research Service (ERS) have each developed a farm typology to classify farms into more homogeneous groups. These typologies provide useful insights into farm structure in each country. It is difficult, however, to use the typologies to compare farm structure in Canada and the United States, because the definitions within the two typologies differ. To make direct comparisons of farm structure in the two countries the Canadian typology was applied to the farms in both nations.

Autores: Serra,   Teresa; Zilberman,   David; Gil,   Jose Maria.
The growing importance of economic factors in farmers’ decision to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. Published analyses so far have not considered differential uncertainties and farmers’ risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between Spanish COP organic and conventional farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different abilities to control production risk as well as different risk preferences. Organic price premiums and...

This study estimated a dynamic logistic model to explain the diffusion Bt cotton in the United States. Regional differences in the speed and extent of Bt cotton adoption were explained by differences in availability of Bt seed adapted to local conditions, potential seed supplier profits, and economic variables affecting grower gains from adoption. The study also estimated the impact of Bt cotton on insecticide use, controlling for differences in pest infestations and prices and correcting for the endogeneity of the Bt adoption decision. Bt cotton significantly reduced insecticide applications to control target pests – cotton bollworm, tobacco budworm, and pink bollworm.

Autores: Arora,   Anchal; Bansal,   Sangeeta.
Recent studies in the literature examining impact of government seed price intervention on adoption of Bt cotton get different results depending on the specifics of the situation analyzed. According to one study, reduction in seed prices enables farmers to buy seeds at lower prices and this can result in surge of area sown under Bt cotton. The other view holds that seed price interventions have little impact on the adoption rates rather these interventions may adversely affect firms’ incentives to innovate. Which of the two views characterize adoption of Bt cotton in India? Using three variations of dynamic logistic model, this paper analyzes the impact of certain economic factors like seed prices, technological development, and cotton prices on the...

Dinâmica econômica das flutuações na produção de cana-de-açúcar
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Satolo,   Luiz Fernando; Bacchi,   Mirian Rumenos Piedade.
Desde meados da década de 70, os mercados brasileiros de açúcar e álcool têm passado por importantes transformações que conduziram o país de volta à posição de líder mundial na produção de cana-de-açúcar. O objetivo deste trabalho é avaliar o papel de choques de oferta (área e produtividade), de demanda (renda doméstica e exportação) e de preços (da cana e de açúcar e álcool) na evolução recente da produção de cana-de-açúcar. Durante a maior parte do período analisado, o setor sucroalcooleiro encontrava-se sob forte regulamentação estatal, com a produção de cana, de açúcar e de álcool limitadas por quotas, preços fixados e exportações determinadas pelo Instituto do Açúcar e do Álcool – IAA. Nos anos 80, a expansão da cana pode ser atribuída aos incentivos...

Disconnections in US and EU Agricultural Policy and Trade Negotiations: A Transaction Cost Politics Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Young,   Linda M.; Hansen,   Kathleen C.
This article investigates aspects of the institutions and decision making processes in the United States and the European Union that affect the coordination of domestic farm programs and trade negotiations for agriculture in each entity. We explore how current institutions and processes contribute to a level of incoherence - or lack of coordination - between domestic farm programs and trade negotiations in the United States. Constructs from transaction cost politics with an emphasis on the decision to delegate authority from the principal to an agent are used to understand how institutional processes affect the coordination of domestic legislation.

Discounting Spotted Apples: Investigating Consumers’ Willingness to Accept Cosmetic Damage in an Organic Product
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Yue,   Chengyan; Alfnes,   Frode; Jensen,   Helen H.
The appearance of organic produce is often less than perfect because of limited methods of avoiding plant diseases. We combine hypothetical and real auction mechanisms to investigate how cosmetic damage affects consumers’ willingness to pay for apples. We find that 75% of the participants are willing to pay more for organic than for conventional apples given identical appearance. However, at the first sight of any imperfection in the appearance of the organic apples, this segment is significantly reduced. Furthermore, the cosmetic damage has a larger impact on the willingness to pay for organic apples than for conventional apples.

Discussion: Animal Identification Systems in North America: Achievements and Future Challenges
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Knutson,   Ronald D.
Although Canada has developed an effective animal identification system, and the provinces are progressing toward a system that has full traceback capabilities, the U.S. and Mexico have made little or no progress. Contemporary U.S. proposals for state initiatives will not work. In the meantime, the U.S. livestock industry will continue to lose markets for its products and has little to no basis for complaining about lost sales and the lack of open markets. Also indentified are relevant economic and political principles that both underlie animal identification systems and the failure to make positive steps forward toward establishing a North American animal identification system.

Discussion: The 2007 Farm Bill and Crop Insurance: Implications for Crop Producers in the South
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Worth,   Thomas.
The crop insurance program has grown significantly since passage of the 2002 Farm Bill. Total premiums more than doubled from $2.9 billion in 2002 to $6.6 billion in 2007. This growth in the crop insurance program is due to a combination of greater participation by growers at higher levels of coverage, an increased number of crops with coverage available, and a general rise in commodity prices. Not unexpectedly, there has been a corresponding increase in the cost of program delivery. The total amount of expense subsidy and underwriting gains paid to crop insurance companies increased from around $1 billion in 20011 to over $2.5 billion in 2007.

DISTORTED PRICES AND PRODUCER EFFICIENCY - ROMANIAN MAIZE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Balint,   Borbala; Sauer,   Johannes.
This research aims at shedding empirical light on the relative efficiency of small-scale maize producers in Romania. Farmers in transition countries still face heavily distorted price systems resulting from imperfect market conditions and socioeconomic and institutional constraints. To capture such distortions we formulate a stochastic shadow-cost frontier model to investigate the systematic input-specific allocative inefficiency. We further adjust the underlying cost frontier by incorporating shadow price corrections and subsequently reveal evidence on farm specific technical inefficiency. Different models are estimated due to the imposition of curvature correctness and the effects on the individual efficiency estimates are shown. The empirical results...

Distortions in Incentives for Production of Major Crops in Pakistan: Recent Trends and Emerging Challenges
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Salam,   Abdul.
Domestic production of wheat, rice, cotton and sugarcane has experienced severe implicit taxation, averaging $1.72 billion per year during 2006-08. These distortions to producer incentives, which have resulted in huge resource transfers, must be removed if Pakistan is to address the recurring crises afflicting the crop sector, alleviate poverty, and achieve sustainable development. The institutional capacity to conduct in-depth policy analysis must also be strengthened.

DISTRIBUTED LAGS AND BARLEY ACREAGE RESPONSE ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Anderson,   Kym.
The need to incorporate production response lags in agricultural supply models is established, and two such lags are considered: the familiar adaptive expectations geometric lag, and a more general polynomial lag. These distributed lag supply response models are applied to Australian barley data for the period 1946-47 to 1968-69. A number of statistical problems associated with the adaptive expectations model are discussed, and in particular it is concluded that lags both in the formation of price expectations and in acreage adjustment should be considered when using geometric lag models. While the polynomial lag model does not provide useful results in the present study, its simplicity and flexibility suggest it may be useful in other studies requiring...

Distribution of Benefits and Adoption of Bt Cotton in Pakistan: Ex-ante Analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nazli,   Hina; Sarker,   Rakhal; Meilke,   Karl D.; Orden,   David.
This poster presents the potential impact of Bt cotton adoption in Pakistan. The size and distribution of economic benefits from the commercial adoption of Bt cotton in Pakistan are examined under four hypothetical scenarios. The adjusted economic surplus model is used to measure total benefits and their distribution between producers, consumers and technology innovators. To account for uncertainty in key parameters, the stochastic simulation techniques is applied. The results show that the total net benefits of adopting Bt cotton in Pakistan are large. As a result of increase in production, farmers get considerable benefits despite a decline in price. The share of benefits to innovators is small. The results indicate that the total cost of adopting latest...

DISTRIBUTIONS OF INDEMNITIES FOR CROP-INSURANCE PLANS: WITH APPLICATION TO GRAIN CROPS IN NEW SOUTH WALES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Battese,   George E.; Francisco,   Emilio M.
A review of crop-insurance schemes is followed by a discussion of a guaranteed-yield, crop-insurance plan. General formulae for the distribution function and mathematical expectation of indemnities for the insurance plan are presented in terms of the distribution of crop yields. Three special cases are considered in which the original yields, the square root of yields, and the logarithm of yields are normally distributed.  The insurance plan is applied on a regional basis for wheat and sorghum production in N.S.W. Given distributional information on the crops obtained from a simulation model, expected indemnities are calculated for four different insurance plans.

Diversification in Indian Agriculture towards High-Value Crops: The Role of Smallholders
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Birthal,   Pratap Singh; Joshi,   P.K.; Roy,   Devesh; Thorat,   Amit.
Agricultural diversification towards high-value crops can potentially increase farm incomes, especially in a country like India where demand for high-value food products has been increasing more quickly than that for staple crops. Indian agriculture is overwhelmingly dominated by smallholders, and researchers have long debated the ability of a smallholder-dominated subsistence farm economy to diversify into riskier high-value crops. Here, we present evidence that the gradual diversification of Indian agriculture towards high-value crops exhibits a pro-smallholder bias, with smallholders playing a proportionally larger role in the cultivation of vegetables versus fruits. The observed patterns are consistent with simple comparative advantage-based production...

DO CORN FARMERS HAVE TOO MUCH FAITH IN THE SUGAR PROGRAM?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rendleman,   C. Matthew; Hertel,   Thomas W.
Corn producers frequently have been told that the sugar program provides an important stimulus to corn demand through its positive influence on the high fructose corn syrup sector. In this article we qualify the extent of this support and find it to be very small- not more than 3 cents per bushel, and probably less. Previous studies have overstated this effect due a lack of attention to the interindustry linkages in the sweetener complex.

Do Decoupled Payments Stimulate Production? Estimating the Effect on Program Crop Acreage Using Matching
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Key,   Nigel D.; Roberts,   Robert J.
This study uses matching to evaluate the effect of decoupled payments on the acreage response of Iowa farmers who were in business in 1997 and 2002. Using farm-level panel data from the U.S. Agricultural Census, we examine whether farmers receiving high levels of 1997 agricultural payments per acre had a greater increase in program crop acreage between 1997 and 2002 than farmers receiving low levels of payments. The panel data set allows for conditioning current acreage on past individual acreage and operator characteristics. The large and exhaustive sample allows for comparisons across similar farms. The matching methodology avoids distributional and functional form assumptions about the relationship between the treatment and outcome. Results are...

Do Farmers Internalise External Impacts of Pesticides in Production?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Skevas,   Theodoros; Stefanou,   Spiro E.; Oude Lansink,   Alfons G.J.M.
In modern agriculture, pesticides feature so prominently in growers’ arsenal to reduce crop damage caused by various pests and diseases. But their indiscriminate use can harm human health and the environment and, eventually, impact agricultural productivity negatively. In an era of an increasing public awareness on the external effects of pesticides, the EU is trying to update its pesticide policy by establishing tax and levy schemes. An important question is whether the external impacts of pesticides are also affecting the farmers’ production environment. A damage abatement specification is used consisting of a potential output function and a damage abatement function. The damage abatement function considers both high and low toxicity pesticides, and...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fabiosa,   Jacinto F.; Jensen,   Helen H.; Yan,   Dong.
This study examines the impact of macroeconomic shocks on the efficiency of small farmers. We estimate single- and multiple-factor efficiency measures for Indonesian rice farmers in years before, during, and after the country's macroeconomic crisis. We find that productive efficiency declined by 7 to 22 percent during the crisis, largely because of a decline in technical efficiency and a relatively large volatility in efficiency (the coefficient of variation was larger by a factor of 1.87). Allocative efficiency, on the other hand, increased slightly and offset part of the decrease in technical efficiency. The magnitude of the impact on efficiency depended on farmers' input adjustments. Factors associated with higher levels of technical and allocative...

Do Refuge Requirements for Biotechnology Crops Promote Economic Efficiency? Some Evidence for Bt Cotton
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Livingston,   Michael J.; Storer,   Nicholas P.; Van Duyn,   John W.; Kennedy,   George G.
We examine producer behavior, resistance evolution, and returns under alternative refuge requirements in an eastern North Carolina region with multiple corn, cotton, and soybean fields infested by a mobile pest. Returns are highest, pyrethroid sprays occur least frequently, and pyrethroid resistance evolution is delayed most effectively with no refuge requirement. Complying with the current 20% refuge requirement costs the producer $8.67 per cotton acre, or $34.21 per non-transgenic insecticidal (Bt) cotton acre. Returns are highest under each refuge requirement when one-toxin Bt cotton is not phased out; however, removal of the technology at the earliest phase-out date minimizes regional pyrethroid sprays.

Does a Rising Biofuels Tide Raise All Boats? A Study of Cash Rent Determinants for Iowa Farmland under Hay and Pasture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Du,   Xiaodong; Hennessy,   David A.; Edwards,   William M.
Iowa’s farmland consists of over 16% hay crops and pastureland, a significant portion of which is under cash rental contracts. This study investigates the comparative relationships between cash rental rates for cropped land and non-cropped land, where the latter includes hay and pastureland. We find that higher crop prices resulting from biofuel demand induces land use conversion from non-cropped land to crop production and thus bids up non-cropped land rents. Compared with changes in cropped land cash rents, non-cropped farmland rents could increase by a higher percentage. Non-cropped land cash rental rates are largely determined by crop and feeder cattle prices, population density, soil quality, and proportion of non-cropped land in a specific area. A...

Does Adoption of Improved Maize Varieties Reduce Poverty? Evidence from Kenya
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mwangi,   Wilfred; Mwabu,   Germano; Nyangito,   Hezron Omare.
Adoption of technologies that increase farm yields is a prerequisite for poverty alleviation in agrarian societies. However, the link between adoption of improved agricultural technologies and poverty reduction is not well understood or documented. This relationship is explored with an example of improved maize seed adoption in Laikipia and Suba - two rural districts in Kenya. We show that adopters of improved maize varieties have higher yields per acre and that poverty is negatively correlated with technology adoption. Policies for increasing diffusion of these technologies include improving access roads to market centers to enhance maize profitability and extension of information about improved maize varieties to farmers.

Using data from fieldwork conducted in Nepal, the impact of a project designed to commercialize vegetables and fruits—the Vegetable and Fruit Cash Crop Program (VFC)—on male and female time allocation is examined. Using a rigorous time collection methodology, activity patterns in households that adopt and do not adopt the new technology are profiled. Very few studies examine changing activity patterns of both men and women in response to commercialization of agriculture. Though women’s time is valuable in agriculture, it is also valuable in the production of child nutrition. The recent evolution in thinking as to the causes of child malnutrition—the three pillars being food intake, health, and time to care—warrants further analyses of the time trade-offs...

We use administrative data from the Federal crop insurance program to examine how yield distributions change as farmers cycle into and out of the program.  We are able to do this by linking many years of crop insurance data by individual farm conditioning observed yields on the particular county and year in which they are observed. Armed with millions of observations, we examine many states and five major crops: corn, soybeans, wheat, rice and cotton.  We find little evidence that yield distributions are affected by insurance.  An exception is rice in Arkansas, where insurance shifts the distribution markedly downward.

Does Duality Theory Hold in Practice? A Monte Carlo Analysis for U.S. Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rosas,   Francisco; Lence,   Sergio H.
The Neoclassical theory of production establishes a dual relationship between the profit value function of a competitive firm and its underlying production technology. This relationship, usually referred to as the duality theory, has been widely used in empirical work to estimate production parameters without the requirement of explicitly specifying the technology. We analyze the ability of this approach to recover the underlying production parameters and its effects on estimated elasticities and scale economies measurements, when data available for estimation features typical realistic problems. We design alternative scenarios and compute the data generating process by Monte Carlo simulations, so as to know the true technology parameters as well as to...

DOES IT MATTER WHO SCOUTS?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lichtenberg,   Erik.
Scouting is the most widely used integrated pest management (IPM) technique.  It has been argued that only independent crop consultants provide unbiased scouting information.  In contrast, chemical dealers inflate scouting reports and/or reduce economic thresholds in order to increase pesticide sales while farmers may use excessively low treatment thresholds due to risk aversion and/or overestimation of pest pressure.  Since the majority of scouting is done by farmers and chemical dealer employees, it follows that scouting may not be a very effective means of reducing reliance on chemical pesticides.  This study applies an implicit demand formulation of the Lichtenberg-Zilberman damage abatement model to data from a survey of Maryland field crop growers to...

Autores: Lichtenberg,   Erik; Berlind,   Ayesha Velderman.
Scouting is the most widely used integrated pest management technique adopted by U.S. growers. This study applies an implicit demand formulation of the Lichtenberg-Zilberman damage abatement model to data from a survey of Maryland field crop growers to examine differences in pesticide demand between growers using scouts trained and supervised by extension and those using chemical dealer employees or scouting themselves. The results give partial support to those skeptical of the quality of scouting by farmers themselves and by consultants working for chemical dealers. Soybean growers using extension-trained scouts had significantly lower pesticide demand than those using chemical dealer employees or scouting themselves. However, no significant differences...

Does Land Use Patterns Matter for Bt-Maize: The Case of Maize Farming System in Kenya
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Muhammad,   Lutta; Owuor,   George; De Groote,   Hugo; Kimenju,   Simon Chege.
Population pressures and the need to optimize the use of limited available land has led to increasing cropping affluence levels within the maize agro-ecologies in Kenya, and a shift from large to smallholder intensification and multiple cropping patterns. Using a geographic information system, this study relates cropping patterns, by area share, maize productivity and household incomes across maize agro-ecologies, with the purpose to establish a decision support system for optimizing land allocation and in priority setting for introduction of new technologies such as Bt maize varieties. Results show that land use patterns and maize productivity in maize farming systems differ between agroecological zones. The high potential areas experience high maize...

Does On-Farm Quality Assurance Pay?  A Cost-Benefit Analysis of the Grainsafe Program
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Karaca,   Umit; Maier,   Dirk E.; Alexander,   Corinne E.
Since the introduction of genetically modified (GM) crops, the commodity grain system has been under pressure to segregate GM and non-GM crops.  Starting at the level of the grain handler, members of the grain supply chain have successfully used quality assurance and identity preservation programs to segregate non-GM crops.  Producers delivering high value, identity preserved crops have become interested in implementing these quality management systems at the farm level.  We conduct a cost-benefit analysis that shows that quality assurance program may be profitable for producers, depending on their farm size and equipment management strategy.

Does Price or Income Affect Organic Choice? Analysis of U.S. Fresh Produce Users
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Smith,   Travis A.; Huang,   Chung L.; Lin,   Biing-Hwan.
This study analyzes consumer purchasing behavior of organic fresh fruits and vegetables using the 2006 Nielsen Homescan panel. An ordered logit model was estimated to quantify the impacts of economic and socio-demographic factors on the probability of a household belonging to a specific organic user group—devoted, casual, or nonuser. Results suggest that price and income, to some extent, affect consumer purchases of organic produce. Additionally, the profile of an organic produce user is most likely to consist of an Hispanic household residing in the Western United States with children under 6 years old and a household head older than 54 years with at least a college degree.

Does Scale Matter? Cost Effectiveness of Agricultural Nutrient Abatement When Target Level Varies
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Iho,   Antti.
Agricultural production is facing high requirements on nutrient runoff reduction. Furthermore, the reductions should by done efficiently. For instance, the European Water Framework Directive calls for cost-effectiveness from schemes of measures to fulfill the target of good water quality in European river basins. In this paper we analyse the implications of target level variation on efficiency properties of agricultural phosphorus abatement. We analyse the robustness of cost-effectiveness as the scheme of measures is adopted from another, identical river basin with different target level on total phosphorus abatement. We find that even between homogeneous regions the cost-effective scheme of measures is unique for all target levels of reduction, and that...

Does Subsidizing Fertilizer Increase Yields? Evidence from Malawi
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ricker-Gilbert,   Jacob; Jayne,   Thomas S.; Black,   J. Roy.
Despite their strain on government and donor budgets, fertilizer subsidies have once again become popular policy tools in several Sub-Saharan Africa countries as a potential way to increase yields in staple crops like maize. Policy makers often assume that farmers who receive the subsidy will achieve yield responses that are similar to those obtained by farmers who pay commercial prices for the input. This notion has not been verified empirically. Our study uses panel data from Malawi, a country that recently implemented a fertilizer subsidy program, to compare maize yield response to fertilizer from farmers who received subsidized fertilizer with yield responses from those who paid commercial prices for the input. Descriptive results indicate that maize...

Dominos in the dairy: An analysis of transgenic maize in Dutch dairy farming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Groeneveld,   Rolf A.; Wesseler,   Justus; Berentsen,   Paul B.M.
Isolation distances to limit the risk of cross-pollination from transgenic to nontransgenic crops can severely limit the potential use of transgenic crops through a so-called 'domino effect' where a field of non-transgenic crops limits adoption of transgenic crops not only on plots in its direct vicinity, but also in plots further away as its neighbors are forced to grow the non-transgenic varieties, forcing their neighbors to grow the non-transgenic variety, and so on. The extent to which this effect takes place, however, may depend crucially on the type of farm. For example, dairy farms can use grassland as a buffer between transgenic and conventional maize plots. This article assesses the effects of isolation distances for transgenic maize in dairy...

Double Transplanting: Economic Assessment of an Indigenous Technology for Submergence Avoidance in the Flood-Prone Rice Environment in Bangladesh
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Azad,   Md Abdus Samad; Hossain,   Mahabub.
In the northern part of Bangladesh a large proportion of land is medium and low-lying which are subjected to the risk of flooding from heavy rains during the month of August and September. Consecutive days of heavy rains after the crop establishment causes flash floods leading to death of seedlings and additional costs for re-transplanting. In response to this environmental problem, farmers practice a system of double transplanting of rice, locally known as Bolon to avoid crop failure from submergence. One-month old seedlings are transferred to another field with dense transplanting, and then re-transplanted to the main after the risk of flash flood is over. Scientists argue that the system would have lower yield and higher costs, thereby lower profits...

DOUBLE-HURDLE MODEL WITH BIVARIATE NORMAL ERRORS: AN APPLICATION TO U.S. RICE DEMAND
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gao,   Xiaoming; Wailes,   Eric J.; Cramer,   Gail L.
Per capita rice consumption in the U.S. has doubled over the past decade. The effects of social and demographic variables on the household's rice consumption decisions are analyzed along with income and price variables. A double-hurdle model is used to solve simultaneously the consumer decisions whether to purchase rice and how much. The joint decision hypothesis is tested and accepted. The non-normal distribution of error terms may be responsible for possible bias in the empirical test of the joint decision hypothesis. The hyperbolic sine transformation is used to correct the problem in this study prior to testing the joint decision hypothesis.

Autores: Hsu,   Jane Lu; Su,   Jyh-Luen.
Fruit production and consumption have increased considerably in the past few decades in Taiwan. Market prices of fruits fluctuate in response to seasonality, changes in production costs, imports and exports, and demand. Some factors are more influential to fruit price changes. This research utilizes the Vector Autoregressive Model to analyze effects of exogenous shocks to market prices of fruits. Dynamic models were developed for bananas, grapes, guavas, papayas, pineapples, and watermelons. For the market of bananas, prices of pesticides have delayed positive effects; an increase of watermelon prices raises the prices of bananas; prices of banana exports explain some variations of domestic banana prices. For the market of grapes, income, interest rates,...

Dynamic and Stochastic Structures of U.S. Cotton Exports and Mill Demand
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fadiga,   Mohamadou L.
This study employs a structural time-series method to model and estimate U.S. cotton exports and mill use. The results show that the stochastic process governing cotton export fluctuations is transitory, while the process pertaining to mill use has transitory, seasonal, and secular origins. The estimated structural relationships after accounting for the unobserved components indicate U.S. cotton exports respond directly to higher international price relative to domestic price of cotton, while mill use responds directly to U.S. textile output price and cotton-to-polyester price ratio. Exchange rate volatility and the U.S. Export Enhancement Program have no significant effect on cotton exports.

Dynamic Changes in Market Structure and Competition in the Corn and Soybean Seed Sector

The purpose of this paper is to analyze the dynamics of R&amp;D investments, and the structure of the seed distribution sector using novel data sets that have not been used before to describe competition in these industries. The results describe four sets of issues of particular importance. One is that while all agbiotechology firms have increased their R&amp;D expenditures, there have been sharp differences in the scope of this spending. Most important is that this has spawned the growth in what is now referred as “seeds and traits.” Second, a large number of future traits will be commercialized in the coming years. A third set of results indicates that one firm grew its market share by 14% and a portion of this growth has been through acquisition. The...

Dynamic Diffusion with Disadoption: The Case of Crop Biotechnology in the USA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fernandez-Cornejo,   Jorge; Alexander,   Corinne E.; Goodhue,   Rachael E.
Controversy over the use of genetically engineered (GE) crops may have induced some farmers to disadopt these seeds, making a traditional diffusion model inappropriate. In this study, we develop and estimate a dynamic diffusion model, examine the diffusion paths of GE corn, soybeans, and cotton, predict the adoption of those crops over the next two years, and explore the main determinants of the diffusion rate. Our estimates indicate that future growth of Bt crops will be slower or negative, depending mainly on the infestation levels of the target pests. Adoption of herbicide-tolerant soybeans and cotton will continue to increase, unless consumer sentiment in the United States changes radically.

DYNAMIC ECONOMIC ANALYSIS OF A RESIDUE MANAGEMENT SYSTEM IN COTTON
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Paudel,   Krishna P.; Lohr,   Luanne.
Residue management system (RMS), comprised of no till cultivation, a winter cover crop, and poultry litter, could be an alternative to existing management system in cotton production in the Georgian Piedmont.  We compare the productivity and profitability of RMS with the current system over time, focusing on the role of organic matter.  Using dynamic bioeconomic modelling technique, we show that the net return and land value difference between these two systems increase as the terminal period increases.  We conclude that if financial and capital markets based on organic matter work efficiently, farmers will choose RMS in cotton production.

In this paper, I use a dynamic recursive computable general equilibrium to evaluate, for the economy of Senegal, the dynamic effects of an economic Partnership Agreement between West African countries and the European Union. In the simulation, the liberalization scheme is designed in a way similar to the interim agreement signed by Cote d’Ivoire and Ghana. The effects described are the shifts from the baseline numbers. I found that the production of agricultural goods will decrease, affecting employment negatively, particularly in unskilled labor, since this sector is very labor intensive. In fact, employment drops at around 0.2 percent a year, during the simulation period (2012-2030). GDP grows on average by 1.9 percent a year. The effects of the economic...

Dynamic general equilibrium analysis of improved weed management in Australia's winter cropping systems
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wittwer,   Glyn; Vere,   David T.; Jones,   Randall E.; Griffith,   Garry R.
A recent analysis indicated that the direct financial cost of weeds to Australia’s winter grain sectorwas approximately $A1.2bn in 1998–1999. Costs of thismagnitude represent a large recurring productivity loss in an agricultural sector that is sufficient to impact significantly on regional economies.Using amulti-regional dynamic computable general equilibrium model, we simulate the general equilibrium effects of a hypothetical successful campaign to reduce the economic costs of weeds. We assume that an additional $50m of R&amp;D spread over five years is targeted at reducing the additional costs and reduced yields arising from weeds in various broadacre crops. Following this R&amp;D effort, one-tenth of the losses arising from weeds is temporarily...

Dynamic Optimization of Fertilizer Application with Carryover and Runoff
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zhou,   Xia (Vivian); Clark,   Christopher D.; Lambert,   Dayton M.
The Economics of fertilizer application has been an interesting issue in regard to crop production (Kennedy et al., 1973). Understanding the temporal dynamics complicates the issue along two dimensions: fertilizer carryover and fertilizer runoff. Fertilizer carryover measures the amount of fertilizer applied in the previous period that is available for crops in current growing period (Kennedy et al., 1973). Fertilizer runoff refers to fertilizer leaving the ground and flowing into water bodies. Thus, the optimal quantity of fertilizer to be applied in the current period depends on the amount of previous application, runoff, and carryover. Because fertilizer carryover and runoff makes optimization of application a complicated intertemporal problem, static...

Alfalfa's heavy reliance on irrigation water and its role as an alternate to program crops makes it susceptible to changes in government farm policies. This article presents a dynamic spatial equilibrium model of the California alfalfa market. The model is used to forecast alfalfa acreage, prices paid and received, and transportation flows for the short run and the long run under the base year conditions. The base year results then are compared to a situation of changing demand due to reductions in federal water subsidies and the implementation of a cotton acreage-reduction program.

Dynamic regulation of nonpoint source pollution when the number of emitters is large

Autores: Tsur,   Yacov; de Gorter,   Harry.
When a nonpoint source pollution process involves many polluters, each taking his own contribution to aggregate pollution to be negligible, ambient-based policies become ineffective due to lack of strategic interactions between dischargers. We offer a regulation mechanism for this case. The mechanism consists of inter-period and intra-period components. The first exploits ambient (aggregate) information to derive the optimal pollution and aggregate emission processes and the ensuing social price of emission. The intra-period mechanism takes as given the social price of emission and implements the optimal output-abatement-emission allocation across the heterogenous, privately informed firms in each time period. The mechanism gives rise to the full...

This paper puts forward a model of the role of phosphorus in crop production, soil phosphorus dynamics and phosphorus loading that integrates the salient economic and ecological features of agricultural phosphorus management. The model accounts for the links between phosphorus fertilization, crop yield, accumulation of soil phosphorus reserves, and phosphorus loading. It can be used to guide precision phosphorus management and erosion control as means to mitigate agricultural loading. Using a parameterization for cereal production in southern Finland, the model is solved numerically to analyze the intertemporally optimal combination of fertilization and erosion control and the associated soil phosphorus development. The optimal fertilizer application rate...

Autores: Rashid,   Shahidur.
Like many other Asian countries, the causal relationship between agricultural productivity and the incidence of rural poverty has been a widely debated subject in Bangladesh. A number of studies argued that the real agricultural wage rate was declining during the period when the country had experienced overall agricultural growth. This paper contributes to this debate in two ways: i) it reexamines the methodological aspects of past studies and presents alternative estimates; and ii) analyzes dynamics of agricultural wage and rice price using the most recent data. Multivariate co-integration techniques are used to examine the long and short-run relationships among agricultural wage rate, rice price, urban wage rate, and other prices. The results show that...

Ecological Goods and Services Survey Summary Prepared for: Lower Souris Watershed Committee
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Entem,   Alicia; Unterschultz,   James R.; Jeffrey,   Scott R.
An interview based survey of farm landowners in the south east corner of Saskatchewan was undertaken to evaluate the provision of wildlife habitat by agriculture. Producers were asked to provide management information regarding a piece of their land that was managed as a unit. Within the past ten years there has been a reduction in the conversion of remaining native land to crop land, an increase in conversion of annual crop land to perennial cover crops, an increase in the use of minimum disturbance (no-till) farming, and a decrease in the use of fire on stubble fields and sloughs. Many producers in the area often stated economic reasons for their current land use division. Even ecological reasons (productive capacity of the soil, poor cropping soil,...

Ecological Risks of Novel Environmental Crop Technologies Using Phytoremediation as an Example
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Angle,   J. Scott; Linacre,   Nicholas A.
Phytoremediation is the use of living plants, known as hyperaccumulators which absorb unusually large amounts of metals in comparison to other plants. The use of classical plant breeding and new molecular techniques offers great potential to develop crops with the ability to clean up polluted sites. While these technologies have gained widespread attention, prior to commercial development, there are risks that must be considered – only a few of which have received even modest examination. Therefore, the focus of this working paper is to explore specific risks associated with phytoremediation and suggest ways in which these risks can be managed so that new, novel, and innovative plant technologies may be applied to provide low cost and efficient...

ECONOMETRIC ESTIMATION OF TART CHERRY SUPPLY RESPONSE TO LOSS OF PESTICIDE ALTERNATIVES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rozanski,   Susan G.
Many agricultural producers are faced with the prospect of fewer chemical alternatives to mitigate damage from pests such as disease, weeds, insects, and rodents. Decreased pesticide availability can arise from health and environmental standards stipulated in federal and state regulations. Pesticide alternatives can also be lost due to natural pest resistance and economic considerations. The loss of pesticides due to economic considerations is especially troublesome to specialty crop producers such as fruit, fresh vegetable, and ornamental growers. Although these producers may use pesticides more intensively per acre than the major crop producers, the total acreage devoted to specialty crops is often not enough to warrant the pesticide registration costs...

ECONOMETRIC INVESTIGATION OF THE DYNAMIC EFFECTS OF THE 1983 PAYMENT-IN-KIND PROGRAM ON THE WHEAT ECONOMY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wang,   George C.; Hassler,   James B.
A stochastic, dynamic, and control-system econometric model of the wheat sector is developed to assess the effects of the Payment-in Kind program.  Empirical results the complex dynamics of the responses.  Reduced storage costs and deficiency payments for the U.S. government and increased income for wheat farmers are benefits from the PIK program in the short-run.  Increased direct government transfers from the public to support the program were required.  The long-run economic implications are not clearly desirable.  This is due primarily to the highly sensitive international wheat market.

ECONOMETRIC PRODUCTION MODELS WITH ENDOGENOUS INPUT TIMING: AN APPLICATION TO ECUADORIAN POTATO PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Antle,   John M.; Capalbo,   Susan Marie; Crissman,   Charles C.
In this article, a model was developed in which the quantity and timing of input and harvest decisions are endogenous.  The endogenous timing model allows all of the information about input and harvest behavior to be utilized, and it provides a basis for linking econometric production analysis to the time-specific analyses in other scientific disciplines used to assess the environmental or human health impacts of agricultural production practices. The case study of fungicide use on Ecuadorian potatoes was conducted with a unique data set containing detailed information on both quantity and timing of input use.  The results showed that both quantity and timing of chemical use were responsive to economic variables.

Autores: Labarta,   Ricardo A.; Swinton,   Scott M.; Black,   J. Roy; Snapp,   Siglinde; Leep,   Richard.
In response to stagnating yields and mounting pest problems, Michigan potato growers are investigating ways to bring manure and cover crops back into potato production systems.  The alternative systems bring benefits and costs for monetary net returns, the variability of net returns, and environmental impacts.  This paper reviews the likely yield and biological system effects of alternative potato production systems that incorporate manure and cover crops.  After briefly considering research designs for gathering experimental versus farm field data, it reviews four economic analysis methods for evaluating alternative systems.  All methods are illustrated with examples.  First, for evaluating comparative average profitability, it reviews a) enterprise...

Autores: Antle,   John M.; Capalbo,   Susan Marie; Mooney,   Sian; Elliott,   Edward T.; Paustian,   Keith H.
This study develops an integrated assessment approach for analysis of the economic potential for carbon sequestration in agricultural soils.  By linking a site-specific economic simulation model of agricultural production to a crop ecosystem model, the approach shows the economic efficiency of soil carbon (C) sequestration depends on site-specific opportunity costs of changing production practices and rates of soil C sequestration.  An application is made to the dryland grain production systems of the U.S.  Northern Plains which illustrates the sensitivity of the sequestration costs to policy design.  The marginal cost of soil C ranges from $12 to $500 per metric ton depending upon the type of contract or payment mechanism used, the amount of carbon...

Economic Analysis of Alternative Maize Storage Technologies in Kenya
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kimenju,   Simon Chege; De Groote,   Hugo.
Upcoming technologies for maize storage have sometimes been promoted without being subjected to trials and economic analysis. In the recent past, new storage technologies, actellic super, super grain bag and the metal silo have been developed. In this paper, the results of crop loss trials are combined with measures of project worth to determine the attractiveness of investing in new storage technologies. Determination of the benefit was based on the amount of loss the new technology could abate. A one ton metal silo, with negligible % crop loss abated USD 100 in 12 months. These benefits were found to increase with time meaning that a farmer benefits by storing longer. Measures of project worth, the NPV and BCR were used to analyze the attractiveness of...

ECONOMIC ANALYSIS OF ENVIRONMENTAL BENEFITS OF INTEGRATED PEST MANAGEMENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mullen,   Jeffrey D.; Norton,   George W.; Reaves,   Dixie Watts.
Public support for integrated pest management (IPM) is derived in part from concerns over food safety and the environment, yet few studies have assessed the economic value of health and environmental benefits of IPM.  An approach is suggested for such an assessment and applied to the Virginia peanut IPM program.  Effects of IPM on environmental risks posed by pesticides are assessed and society's willingness to pay to reduce those risks is estimated.  The annual environmental benefits of the peanut IPM program are estimated at $844,000.  The estimates of pesticide risks and willingness to pay can be applied elsewhere in economic assessments of IPM.

Autores: Singh,   Rajinder Pal; Brennan,   John P.; Farrell,   Tim; Williams,   Robert L.; Rienke,   Russell; Lewin,   Laurie; Mullen,   John D.
The occurrence of low night temperatures during reproductive development is one of the factors most limiting rice yields in southern Australia. Yield losses due to cold temperature are the result of incomplete pollen formation and subsequent floret sterility. Researchers have found that in 75% of years, rice farmers suffer losses between 0.5 and 2.5 t/ha. Research is being undertaken to identify overseas rice varieties, that are cold tolerant under the local weather conditions and by using those genotypes as parent material, develop cold tolerance varieties of rice. A yield simulation model was used to measure reduction in losses due to cold at different minimum threshold temperatures, while the SAMBOY Rice model was used to measure the costs and returns...

Autores: Beltran,   Jesusa C.; Pannell,   David J.; Doole,   Graeme J.; White,   Benedict.
This paper describes a dynamic simulation model that has been developed to provide a comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems. The main outputs of the model include weed seed and plant densities and seasonal and annualised profit over the simulated planning horizon. Model output emphasises the substantial economic benefits associated with effective long-term weed management strategies. In addition, a mixture of chemical and non-chemical treatments provides good weed control in rice crops, and maximises long-term profit for systems where the main weed is annual barnyardgrass. However, the performance of this strategy is...

The Department of Agricultural Research (DAR) in Malawi has made a modest contribution to small farmers in supplying them with recommendations they can adopt.  This was largely due to the biological emphasis of the department. In order to introduce social scientists and following in recognition of the poor adoption of recommended technology, Farming System Research (FSR) was introduced in 1979.  That has now changed to Adaptive Research.  This also followed a major reorganization of the department into Commodity and Adaptive Research Teams.

Variable-rate (VR) application of inputs in South African cash crop production is mainly concerned with fertilizer and lime, and this indicates the importance of these inputs in cash crop production. However, the profitability of VR application of inputs has not yet been investigated under South African conditions. This paper studies the maize yield response to variable-rate application of phosphorus (P) and the profitability thereof in South Africa, on the basis of data collected on a 104-hectare experimental field on a farm in the Bothaville district. The strip-plot design of 180 strips was used for this on-farm research experiment. This design involved treatments that run in the same direction across the field as planting and harvesting.

The paper analyzes site-specific and uniform management options for wheat production with respect to grain quality. Besides site-specific fertilization the economic potential of segregation of different grain qualities is the subject of this paper. Yield and quality response to fertilizer were taken from field experiments in Germany to calculate site-specific response functions. The economic optima were calculated for uniform management (UM), complete separate management of the subfields (SM), site-specific fertilization (SSF) and grain segregation (GS) for different price structures according to different grain qualities. The results show that over all price structures, highest economic potential was found with SM or SSF compared to UM. However, these...

This paper addresses the question of summer cover crop adoption by farmers in presence of a risk of yield loss due to take-all disease and climate variability. To analyse the public incentives needed to encourage farmers to adopt summer cover crops as a means of reducing N leaching, we combine outputs from an economic, an epidemiological and an agronomic model. The economic model is a simple model of choice under uncertainty. The farmer is assumed to choose among a range of summer fallow managements and input uses on the basis of the expected utility criterion (HARA assumption) in presence of both climate and take all risks. The epidemiological model proposed by Ennaïfar et al. [1] is used to determine the impact of take all on yields and N-uptake. The...

ECONOMIC ANALYSIS OF TEMIK ON CITRUS IN THE INDIAN RIVER AREA IN SOUTHEASTERN FLORIDA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blakeley,   Lindsey; Weldon,   Richard N.; Fairchild,   Gary F.
Temik [R](aldicarb) is a pesticide labeled for use on several citrus crops to control rust mite, whitefly, nematode and brown citrus aphid pests. Analysis of previous research experiments indicates that this pesticide is beneficial to both orange and grapefruit production and that both cost savings and higher yields can be experienced in many types of groves. Actual grove data shows that net returns for mature grapefruit that receive Temik [R] can be $500 per acre greater than net returns for identical acreage that uses other pest control options. Also, based on grove reset data it is shown that with an application of Temik [R] the resulting increased yields for three-year-old trees more than cover the additional cost of applying the Temik [R].

Recent research shows initial colonization of potato fields by winged green peach aphid is concentrated at field edges.  This suggests that insecticides applied only to field margins during initial colonization would largely eliminate a colonizing aphid population, conserve natural enemies in the field center, and reduce insecticide use.  To better understand the costs and benefits of reducing organophosphate use, the six participating growers were interviewed to ascertain their reason for participating and their satisfaction with the border only treatment method as well as their estimated net economic benefits.  Five of the farms ranked cost reduction as the most important reason for participating.  The sixth farm ranked reducing virus spread as the most...

Mushrooms have been grown commercially on many different substrates for years, usually agricultural by-products such as straw or stover.  Increased popularity for specialty mushrooms with consumers has led to increased production and great demand for economic substrates.  Oyster mushrooms are easier to grow relative to other types of mushrooms and their production has increased dramatically in recent years.  This study examines the economic feasibility of using soybean hulls as a primary substrate for oyster mushrooms, replacing traditional wheat straw.  The study uses a cost-benefit analysis to determine an optimal substrate based on yield and the number of crops harvested per year.   The study shows that soybean hulls, combined with corn gluten or...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ribaudo,   Marc; Hurley,   Terrance M.
Restricting or eliminating the use of atrazine in the Midwest would have important economic consequences for farmers, consumers, and the environment.  These consequences can only be evaluated with cooperation between economists and weed scientists.  The weed control choice set available to farmers cannot be observed through deductive research.  Economists and weed scientists worked together to identify all possible weed control strategies for corn and sorghum in the Midwest and to incorporate them into an economic model.  An atrazine ban was found to be the costliest strategy, and a targeted, water-quality based strategy the most cost effective.

ECONOMIC AND HYDROLOGIC IMPLICATIONS OF SUSPENDING IRRIGATION IN DRY YEARS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Keplinger,   Keith O.; McCarl,   Bruce A.; Chowdhury,   Manzoor E.; Lacewell,   Ronald D.
A dry year irrigation suspension has been proposed as a way of reallocating water when aquifer levels are low for the Texas Edwards Aquifer. Under this program, farmers would be paid to suspend irrigation to allow more spring flow or nonagricultural pumping. When irrigation is suspended in the east, springflow response is markedly larger than when suspended in the western portions of the aquifer. Most acreage participates when a $90 per acre payment is offered before the cropping season. Considerably higher payments are needed and less water saved for a suspension program instituted during the cropping season.

This paper examines the technical and institutional efficiency of the National Agricultural Advisory Services (NAADS) programme implementation in Iganga district. The Cost Effective Analysis (CEA) and stochastic frontier analysis methods were used to examine technical efficiency while expenditure tracking and FGD methods were applied to assess institutional efficiency. The analysis demonstrates that NAADS interventions have not had a significant impact on the output, productivity and income of the farmers in Iganga district. Moreover, NAADS programme faces implementation weaknesses such as nepotism that affects the selection of beneficiaries as well as enterprises, to the extent that some farmers are apathetic about the success or failure of NAADS...

Economic and Marketing Efficiency Among Corn Ethanol Plants
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sesmero,   Juan P.; Perrin,   Richard K.; Fulginiti,   Lilyan E.
We extend data envelopment analysis (DEA) to decompose the economic efficiency of a sample of ethanol plants into internal (technical and allocative) and boundary (marketing) sources. This decomposition allows us to evaluate the channels through which different plant characteristics affect plant performance. Results show that plants are very efficient from a technical point of view. Plants with higher production volumes seem to perform better not because of economies of scale but because they can secure more favorable prices (higher marketing efficiency) and execute production plans accordingly (higher allocative efficiency). This may rationalize the increase in the size of the average plant observed in the industry in recent years despite evidence of...

ECONOMIC AND TECHNICAL ANALYSIS OF ETHANOL DRY MILLING: MODEL DESCRIPTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dale,   Rhys T.; Tyner,   Wallace E.
Ethanol, the common name for ethyl alcohol, is fuel grade alcohol that is predominately produced through the fermentation of simple carbohydrates by yeasts.  In the United States, the carbohydrate feedstock most commonly used in the commercial production of ethanol is yellow dent corn (YDC).  The use of ethanol in combustion engines emits less greenhouse gasses than its petroleum equivalent, and it is widely hoped that the increased substitution of petroleum by ethanol will reduce US dependence on imported oil and decrease greenhouse gas emissions.  Production of ethanol within the United States is expected to double, from 3.4 billion gallons in 2004, to about seven billion gallons in the next five years.    Two processes currently being utilized to...

Economic Aspects of Revenue-Based Commodity Support
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cooper,   Joseph C.
Interest in revenue-based commodity support is evident in the Food, Conservation and Energy Act of 2008 (the 2008 Farm Bill), which gives eligible producers the option of participating in the Average Crop Revenue Election (ACRE) program in return for reductions and eliminations of payments under more traditional programs. This report examines how the uncertainty in U.S. domestic commodity support payments for corn may differ between traditional-style approaches (defined as price-based payments plus yield-based disaster payments) to support and two revenue-based support scenarios. Variability around the total expected annual payment was found to be lower under revenue-based support, as was the probability of high payments. These results suggest potential...

Economic Aspects of the California Nursery and Floral Industry, 2001–2009
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carman,   Hoy F.
California’s nursery and floral industry is the largest in the United States with a farm value for product sales totaling $3.78 billion in 2009. When floral and nursery product sales are combined, the industry ranks second among all California agricultural products, following the dairy industry. Production is in 55 of California’s 58 counties, although 16 counties account for more than 87% of the value of production. San Diego County dominates the industry with annual sales over $1 billion in 2007, 2008, and 2009. Since its 2008 and 2009 sales increased while California’s statewide sales decreased, San Diego County increased its share of California sales from 26% in 2007 to 30.3% in 2009.  California is the largest single retail market for lawn and garden...

ECONOMIC ASPECTS OF THE POTATO ENTERPRISE WITH PARTICULAR REFERENCE TO COSTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kearney,   Brendan.
Although potatoes are grown in most countries of the world, the pattern of production is largely concentrated in Europe where almost three-quarters of the world's acreage is grown. The Americas account for somewhat over 7 percent of total acreage of which over one-half is grown in the southern continent.  In terms of production, this concentration is even more marked with 86 percent of the total coming from the aforementioned areas.  Thus it is noted that it is in European countries and those areas of the world largely populated by the descendants of Europeans that the potato finds favor despite the fact that it originated in Peru and was first used by peoples of Asiatic origin as an item in their diet.

Economic benefits to Papua New Guinea and Australia from the biological control of banana skipper (Erionota thrax)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Waterhouse,   Doug F.; Dillon,   Birribi; Vincent,   David P.
Larvae of the butterfly Erionota thrax, the banana skipper, destroy the leaves of bananas by eating them and forming massive protective rolls of leaf tissue. They were first observed in north-western Papua New Guinea in 1983 and over the next 6 years spread throughout the mainland at the rate of up to 500 km/year.  E. thrax has also spread across the ocean to the east, to invade New Britain, Duke of York and New Ireland islands, and possibly Bougainville.  As the banana skipper spread, it destroyed an average of some 60% of banana leaves, leading to both a serious delay in fruit maturation and reduced weight of banana bunches. Previous successful biological control of E. thrax when it invaded Mauritius, Hawaii, Guam and Saipan encouraged Papua New Guinea...

Environmental concerns about pesticide usage in traditional production systems are prompting vegetable producers to consider alternative systems. Research results from a multi-year study on eggplant in southern Georgia compare two alternative production technologies to the conventional rye cover crop technology. Alternative technologies utilize beneficial insect principles as substitutes for conventional pesticide controls. Using field data, eggplant production budgets are developed to generate net return estimates under each system. Cost reductions achieved by using alternative technologies are not sufficient to offset the reduced yields and returns generated from these technologies. Cash input requirements for alternative systems suggest potential for...

The purpose of this study was to measure the economic contribution of the soybean industry to the North Dakota economy. Expenditures and returns from soybean production, grain handling, and transportation were estimated to calculate the direct economic impacts from soybean activities. Secondary economic impacts were estimated using the North Dakota Input- Output Model. Soybean production in North Dakota has trended upward over the past three decades. Increases in acreage were relatively modest in the 1980s, but by the mid 1990s acreage was beginning to rapidly expand. In 1990, North Dakota had about 500,000 acres of soybeans. By 2000, acreage had increased to 1.9 million acres. By 2009, soybean acreage in the state was approaching 4 million acres. Direct...

Economic Determinants of Invasion and Discovery of Nonindigenous Insects

Introductions of nonindigenous organisms into the United States have been linked to international trade. The individual contributions of imports, immigration, and international travel, however, are poorly understood because introduction dates are unavailable. We examine relationships between economic trends and discoveries of nonindegenous insects and use these relationships to infer the timing and determinants of introductions. We find that a few variables can explain much variation in species introductions and identifications. The most significant contributor to the introduction appears to be agricultural imports. Currently available proxies for academic effort are weak determinants of the probability that introduced species are identified.

Economic evaluation of a weed-activated sprayer for herbicide application to patchy weed populations
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bennett,   Anne L.; Pannell,   David J.
Spatial distribution of weeds in a crop is patchy. Traditional boom sprayers waste herbicide by applying it to areas where weed density is already low. A new technology, Weed Activated Spray Process (WASP), uses sensors to detect the presence of weeds and control spray nozzles accordingly. The economic benefits of this technology to extensive crop farmers in Western Australia are investigated using a model based on the economics of information. Existing technology is likely to reduce profits because the weed density at which it switches off spraying is too high. Even if sensitivity to low densities could be improved, likely benefits of pre‐crop usage would still be very low or negative.

Economic Evaluation of Bt Corn Refuge Insurance
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mitchell,   Paul D.; Hurley,   Terrance M.; Hellmich,   Richard L.
The EPA has imposed mandatory refuge requirements for Bt crops to prolong the efficacy of Bt. Growers have no economic incentive to plant the required refuge because refuge crops are on average less productive and more risky. This paper evaluates refuge insurance—insurance thatpays indemnities for yield losses on refuge due to insect damage—as a tool to increase grower compliance incentives. We determine actuarially fair insurance premiums, then evaluate the feasibility of private provision of refuge insurance and its impact on grower incentives to comply with refuge requirements. A private market for refuge insurance appears unlikely because our analysis suggests that even a 2 percent load on the actuarially fair premium makes growers unwilling to buy...

Structural adjustments programs (SAPs) in the last two decades have eliminated all farm-support programs leading to low usage of fertilizers by Kenyan smallholders. One way of addressing this problem is use of organic nutrient resources. This paper examines their cost-effectiveness as capital investments in replenishment of Nitrogen (N), Phosphorus (P), Potassium (K) and soil organic matter (SOM) in smallholder, Maize-based cropping systems. On-farm trials were established in Maragwa and Kirinyaga Districts in 2003/04. Maize was planted in 3 replicates in randomised complete block design (RCBD) using different levels of organic and inorganic fertilizer resources.

The effect of nine different fungicide seed treatments for soybeans were tested from 2004 to 2007 at Keiser, Stuttgart, and Hope, Arkansas. While seedling emergence was effective across all treatments, only three treatments showed statistically significant differences in partial returns, defined as gross revenue minus seed and seed treatment costs. Comparisons of the regret a producer would experience as a result of non-optimal seed treatment suggested that broad spectrum seed treatment could enhance profitability by an average of $32 per acre with similar treatment recommendations across a range of seeding rates, output prices and study conditions.

Burning of rice stubbles is widely practised in Punjab, India, due to a lack of suitable machinery to direct drill wheat into combine-harvested rice residues. Although burning is a rapid and cheap option, and allows quick turn around between crops, it has serious effects on human and animal health due to air pollution, reduced soil fertility due to loss of nutrients and organic matter, and green house gas (GHG) emissions. The recently developed Happy Seeder (HS) overcomes the technical problems associated with direct drilling into rice residues. The primary aim of the present study was to conduct a preliminary evaluation of the direct financial benefits and costs to farmers of use of the HS in comparison with the current practices of straw burning followed...

Autores: Wu,   Jinzhuo; Sperow,   Mark; Wang,   Jingxin.
A mixed-integer programming model is developed to assess the economic feasibility of siting a woody biomass-based ethanol facility in the central Appalachian hardwood region. The model maximizes the net present value (NPV) of a facility over its economic life. Model inputs include biomass availability, biomass handling system type, plant investment and capacity, transportation logistics, feedstock and product pricing, project financing, and taxes. Four alternative woody biomass handling systems, which include all processes from stand to plant, are considered. Eleven possible plant locations were identified based on site selection requirements. Results showed that the optimal plant location was in Buckhannon, West Virginia. The NPV of the plant with a...

Economic Feasibility of Kenaf Production in Three Tennessee Counties
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bazen,   Ernest F.; Roberts,   Roland K.; English,   Burton C.
Since the 1940s, kenaf has been viewed as a potential source of fiber, mainly for newsprint and high quality paper. Kenaf research has once again risen to the forefront due to the recent USDA tobacco buyout. Many states and farmers dependent upon tobacco revenues have been seeking alternative crops for a number of years. This study seeks to expand the current literature by examining the economic feasibility of growing kenaf within three counties in Tennessee. Nitrogen meta-yield response functions for kenaf and four traditional crops were developed for 30 soils through crop growth simulation modeling and used to compare optimal crop budgets for each soil. Results reveal that kenaf would not compete favorably with traditional crops on any soil at prices...

Declining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand. From an exclusive IWMI perspective, the impact evaluation suggests that the program has a net present value (NPV) of US$0.41 million with a benefit-cost ratio (BCR) of 2.44...

Autores: Rudi,   Nderim; Norton,   George W.; Alwang,   Jeffrey Roger; Asumugha,   Godwin N.
Marker-assisted breeding could have a major impact in relieving productivity constraints that cannot as easily or rapidly be relieved by conventional breeding alone. This paper estimates the benefits of using marker-assisted breeding, as compared to conventional breeding alone, in developing cassava varieties resistant to cassava mosaic disease, green mite, whitefly and post-harvest physiological deterioration in Nigeria, Ghana and Uganda. Marker-assisted breeding is estimated to save at least four years in the breeding cycle for varieties resistant to the pests and to result in incremental net benefits over 25 years in the range of $34 to $800 million depending on the country, the particular constraint and various assumptions. Benefits may reach as high...

The benefits of developing and releasing salinity-tolerant and phosphorous-deficiency-tolerant rice in Bangladesh, India, Indonesia and the Philippines were estimated for marker-assisted breeding as compared to conventional breeding using economic surplus analysis. Marker-assisted breeding is estimated to save at least 2 to 3 years in the breeding cycle and result in incremental benefits over 25 years in the range of $300 to $800 million depending on the country, stress, and time lags. Salinity and phosphorous deficient soils are difficult problems to solve through conventional breeding because of “genetic load” or undesirable traits that accompany desirable ones during backcrossing.

Economic Impact of a Proposed AGI Means Test on Representative Crop Farms
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Richardson,   James W.; Outlaw,   Joe L.; Raulston,   J. Marc.
The Administration has proposed revising the AGI means test for eligibility to farm program payments. The 2002 farm bill excludes producers from farm program payments (CCP, DP, and MLG/LDP) if their average adjusted gross income (AGI) for three preceding years exceeds $2.5 million and less than 75% of their AGI comes from farming, ranching or forestry operations. The revised means test would reduce the AGI cut-off to $200,000 and repeal the 75% exclusion. The purpose of this report is to estimate the impacts of the AGI proposal on average annual government payments and real net worth in 2014 for representative crop farms. The AFPC maintains a data base of 64 representative commercial family farms in major production regions across the United States. The...

This study employed the Ricardian approach to test the relative importance of climate normals (average long-term temperature and precipitation) in explaining net revenue from Nigerian rice agriculture under irrigation and dry land conditions.   A survey was done by interviewing 1200 rice farmers from 20 rice producing states in Nigeria. The states covered all the six geopolitical zones in the country. The results showed that increase in temperature will reduce net revenue for dry land rice farms while net revenue rises with increase in temperature for irrigated rice farms. Precipitation had similar effects on rice net revenue. Increase in precipitation will cause reduction in revenue for dry land rice farms whereas it will cause increase in revenue for...

Autores: Nganje,   William E.; Johnson,   D. Demcey.
FHB and DON present significant challenges to producers, grain elevators, and the brewing industry. Yield reductions and price discounts incurred by producers in North Dakota, Minnesota, and South Dakota averaged about $45.3 million annually during the years 1998 through 2000. Losses are more substantial when secondary economic impacts are considered. For every $1 of scab losses incurred by the producer, $2 in losses are incurred in other areas of rural and state economies. One way of mitigating these losses is to blend barley with DON and barley without DON. Results from the grain blending model show a sharp decline of DON discounts and losses after blending. The average discount fell from $0.57/bu to $0.17/bu in 1998, $0.48/bu to $0.14/bu in 1999, and...

Agricultural areas can be significantly impacted by high-value crops.  Irrigated potato production has significantly affected central North Dakota.  Interested growers in the Jamestown area recognized the need and the potential for irrigated potato production and processing, and eventually convinced a private company to build a processing plant to make frozen potato products from their irrigated potatoes.  Securing a private entity to process their product freed up capital for irrigation development and other potato enterprise purchases.  Economic impacts resulting from the addition of irrigated potatoes and associated processing were analyzed in this study.  This analysis is divided into two parts, construction/start-up (one-time) and operational...

Managing quality risks, especially grain quality, has been a challenge facing farmers, grain merchandisers, and policymakers for many years.  With the advent of genetically modified organisms (GMOs), food safety, and identity preservation, this is even more challenging today.  In this paper, an equilibrium crop insurance model was developed and used to analyze the impact of quality risks on equilibrium coverage levels and risk premiums that suppliers of insurance and barley producers would be willing to provide when yield and revenue insurance instruments explicitly incorporate quality risks.  The asking price concept and sensitivity analysis were used to evaluate farmers' behavior after they purchase crop quality insurance and to provide guidance and...

Public health officials and physicians are concerned about possible development of bacterial resistance and potential effects on human health that may be related to the use of antimicrobial agents in livestock feed. The focus of this research is aimed at determining the economic effects that subtherapeutic bans of antimicrobials would have on both swine producers and consumers. The results show that a ban on growth promotants for swine would be costly, totaling $242.5 million annually with swine producers sharing the larger portion in the short run and consumers sharing about 75% in the long run. If a ban affected poultry as well as pork production, the total costs would expand to $586 million per year with swine producers sharing about the same as in bans...

This paper explores some possible economic impacts of worsening salinity severity and extent in the grains industry across Australia. It also looks at the potential to increase agricultural profits through remediation. The analysis is based on a spatial model of agricultural profits and salinity related crop/pasture yield losses. It is estimated that grains industry farming profits across Australia would rise by an upper limit $138 million per year were salinity costlessly removed from the landscape. It is also estimated that the present value of grains industry profit losses from worsening salinity extent and severity over the next 20 years is $237 million. These amounts can be considered against the costs of repair.

China has made a major investment in biotechnology research.  Genetically modified (GM) cotton is widely adopted and the list of GM technologies in trials is impressive.  At the same time there is an active debate on when China should commercialize its GM food crops.  The overall goal of this paper is to provide an economy-wide assessment of these issues under various scenarios.  Based on a unique data from empirical micro-level study and field trial in China and a modified GTAP model, our results indicate that the development of biotechnology has an important impact on China's production, trade and welfare.  Welfare gains far outweigh the public biotechnology research expenditures.  Most gains occur inside China.  Policy makers should put less weight on...

Implications of increasing labour cost and development of herbicide resistance for profitable weed management in Philippine rice farming systems are investigated. The study employs RIMPhil (Resistance and Integrated Management in the Philippines), a bioeconomic simulation model developed to provide a comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice crops. Results indicate that herbicide application will become increasingly economically attractive, relative to manual weeding, as labour cost increases. This is important since urban migration in the Philippines continues to increase the scarcity of rural labour. Results also show that the onset of herbicide resistance...

A national pesticide-use survey from sorghum producers and a survey of entomologists and weed scientists were used to determine the impacts of pesticide use on sorghum. A market framework was employed to derive the short-run welfare impacts to consumers and producers (users and non-users) of the removal of pesticides currently registered for use on sorghum. It was projected that the loss of atrazine, the most widely used pesticide in sorghum production, would have the largest overall impact, with an estimated total welfare loss between $58 and $65 million.

This paper estimates the direct and indirect impacts of the Pink Hibiscus Mealybug infestation on the economies of Florida and the rest of the United States. The approach involves a Markov chain analysis wherein both short run and long run expected damages from infestation are calculated. Use is made of the CLIMEX model that predicts the potential pest-establishment regions in the US. While predictions based upon the CLIMEX model extend the scope of damages beyond Florida, the damages are dependent upon the rate of arrival and detection of species in those regions. Damages are significantly higher when a longer time horizon is considered. When nursery owners bear the full cost of quarantines in the form of loss of sales and treatment costs of infected...

The spread of Asian Soybean Rust (ASR) represents a real threat to the U.S. soybean sector. We assess the potential impacts of ASR on domestic soybean production and commodity markets as well as the competitive position of the US in the soybean export market. We develop a mathematical stochastic dynamic sector model with endogenous prices to assess the economic impacts of ASR on US agriculture. The model takes into account the disease spread during the cropping season, the inherent uncertainty regarding the risk of infection, and the dichotomous decisions that farmers make (no treatment, preventive treatment, and curative treatment) facing the risk of infection. Our results suggest substantial impacts from potential ASR spread on agricultural output,...

We estimated the economic benefits resulting from controlling soybean aphid infestation by using a multi-regional competitive dynamic equilibrium model. Results indicate that the reduction of soybean production resulting from a soybean aphid infestation is largely absorbed by reducing soybean exports, due to the higher price elasticity of export demand compared to domestic demand. Producer benefits resulting from controlling soybean aphids would increase by between $949 million and $1.623 billion in ten years under various scenarios. Results also suggest that it is economically more efficient to control soybean aphids when the rate of intrinsic growth is relatively lower, the supply price elasticity of soybean acreage is relatively more elastic, and...

While the significant ecosystem damage caused by invasive weeds has been well documented, the economic impacts of specific invasive weed species are poorly understood. Yellow starthistle (Centaurea solstitialis L., hereafter YST) is the most widespread non-crop weed in California, resulting in serious damage to forage on natural range and improved pasture. A survey was administered to California cattle ranchers to investigate YST infestation rates, loss of forage quantity and value, and control or eradication efforts. The results were used to estimate county-wide economic losses for three focus counties, as well as state-wide economic losses, due to YST in California. Total losses of livestock forage value due to YST on private land for the state of...

Autores: Chen,   Changping; Fletcher,   Stanley M.
This study analyzed the potential economic impacts of the FAIR  Act under GATT and NAFTA on the U.S. peanut industry.  Results indicate that the economic impacts of the new program combined with the trade agreements are profound on the peanut industry in both short and long terms.  Changes of the peanut program could decrease peanut producers' farm income substantially, eliminate government financial costs related to excessive quotas, and transfer peanut growers' program benefits back to peanut consumers.  Increasing imports of foreign peanuts due to free/reduced trade barrier agreements would transfer peanut producers' program benefits to domestic peanut importers and foreign exporters who sell peanuts to the U.S.  Note: Tables 3 and 4 not included in...

Economic Implications of the Methyl Bromide Phaseout
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Osteen,   Craig D.
The pesticide methyl bromide is being phased out internationally under the Montreal Protocol. Methyl bromide has been used for over 50 years to control insect, nematodes, pathogens, and weeds. It is used for soil fumigation before planting many fruits, vegetables, ornamentals, and agricultural nurseries; for post-harvest fumigation of commodities in storage and prior to shipment; and for government-required quarantine treatment to prevent the spread of regulated exotic pests. Many U.S. users are concerned that existing alternatives to methyl bromide will be less effective and cause financial losses. To help mitigate the impacts of the phaseout, USDA, the U.S. Environmental Protection Agency (EPA), universities, and private firms are working to develop new...

Recognizing that the green revolution has resulted in considerable success in production of rice and wheat in many Asian countries, which are now self-sufficient or surpluses in these cereals, IFPRI believes that further growth in agriculture will rely on the productivity of these countries to diversify their agricultural production, while improving productivity in cereals through management and human capital-intensive increase in yield levels. Indonesia is an important example of a country where policy successes in rice production combined with other domestic and world developments in the economic environment of agriculture encouraged policymakers to consider agricultural diversification policies. Key developments leading to an increased interest in...

Autores: Rahim,   Afaf H.; van Ierland,   Ekko C.; Wesseler,   Justus.
The gum tree (Acacia senegal) in the Sahel-Sudan zone has many environmental benign functions. An important function is to control desertification. In this paper we analyze farmers' economic incentives to preserve the existing gum trees and their incentives to create new plantations using a real options approach. Results indicate that agricultural crops provide higher economic benefits as compared to gum agroforestry system. However, on the one hand, as gum arabic is produced during the dry period and land is abundant, there are low incentives for deforestation. Instead, farmers' tend to leave the land idle and let the tree growing. On the other hand, our results suggest that an increase in the prices of gum arabic of about 330 per cent is needed to induce...

Economic Issues in Assessing Research Priorities in Feed Grains Nutrition
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brennan,   John P.; Singh,   Rajinder Pal; Singh,   Inder Pal.
Researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, an attempt to address those research resource allocation issues is reported. The approach to use in analysing improvements in the feed quality of grains is discussed. By defining the problem as a cost reduction for the livestock industries, the impact of improvements in grain nutrition can be defined by their impact on the least-cost feed rations for different livestock categories. Using that approach, the benefits of improved feeds can be evaluated, and research priorities can be determined on the basis of which...

Autores: Brennan,   Donna C.
In this paper, the literature on the economics of grain distribution systems is reviewed. The emphasis of this review is on farm to port issues and largely excludes port and shipping issues. In the first part of the paper, the discussion centres on the historical institutional environment in Australia, which was heavily regulated. The second part of the paper highlights some of the issues relating to the pricing of central grain distribution services that continue to exist even in the more competitive environment which has emerged in the 1990's. The scope for future agricultural economics research in this area is discussed.

Autores: Schmidt,   Carmel P; Pannell,   David J.
Herbicide-resistant annual ryegrass (Lolium rigidum) is having a dramatic impact on the management and profitability of continuous cropping systems of southern Australia. In many cases ryegrass populations have exhibited cross resistance. where development of resistance through repeated use of one herbicide also bestows resistance to other groups of herbicides not previously used. Hence use of the major groups of selective herbicides as the predominant means of weed control is often ruled out. In this paper we discuss the development of herbicide resistance in Lolium rigidum, its costs and implications for farm management. Where high levels of resistance have developed, weed control strategies that include a range of control methods (such as increased crop...

The majority of the cotton farms are in poor overall financial condition under the August 2006 Baseline. Drought conditions this year will deplete cash built from more favorable yields in 2004 and 2005 in many cases. In addition, the poor financial performance of the farms is attributed in part to the large increase in input prices. Fuel costs, previously projected to decrease modestly in 2005 and 2006, are now more accurately depicted as significant increases, building further on the large increases experienced in 2003 and 2004. The increase in cost is not limited to fuel expense for trucks, equipment, and irrigation motors, but includes the cost of nitrogen fertilizer and ag-related services which are closely linked to energy prices.

Economic Performance of Bt Cotton Varieties in Pakistan
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nazli,   Hina; Sarker,   Rakhal; Meilke,   Karl D.; Orden,   David.
Farmers in Pakistan have been growing cotton that contains the first generation of Bt gene since 2002. The cultivation of these varieties, although formally unapproved and unregulated, increased rapidly after 2005. In 2007, nearly 60 percent of the cotton area was under BT varieties. This paper examines the economic performance of Bt cotton in Pakistan based on data collected through a structured questionnaire survey in January-February 2009 in two districts (Bahawalpur and Mirpur Khas). The extent of the impact of Bt cotton on costs of production and yield gains are different across the two districts with their diverse agro-climatic conditions and pest pressures. Seed expenditures increase in both districts, but a decline in the number of bollworm sprays...

Economic possibilities in the integrated wheat production through the agri-environment measures in a Hungarian agricultural enterprise
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nemeth,   Barbara; Fodor,   Attila.
The payment amount of the entry level scheme significantly exceeds the additional costs which arise from abiding by the regulations and with this the financial situation and competitiveness of the viable agricultural enterprises may improve. Based on the pre-calculation in relation to the fortuituos entry into the integrated target scheme it can be concluded that the additional cost determined by the target scheme would only use up just about half of the surplus payment allotted through the integrated target scheme. It is well-worth to make use of the opportunities given by these schemes, because through them the enterprise can obtain a regular, secure and significant income.

A comprehensive set of potential new feed grains for Australia was evaluated to help establish the options with the highest priorities for research. The cost-reducing impacts of the different options were analysed using a linear-programming model that determined the least-cost feed rations for the different livestock industries. Economic welfare analysis was then used to estimate the size and distribution of the benefits of research from the feed grains quality-improving research. The analysis revealed that there are only limited opportunities to improve the productivity and competitiveness of Australia’s livestock industries by improving the nutritional characteristics of feed grains.

Stocker cattle grazing warm season perennial grasses is an important economic activity in the southern Great Plains.  Substantial increases in the price of nitrogen fertilizer is negatively affecting forage producers’ profitability.  Two alternative nitrogen management systems that use annual and perennial legumes have been developed for bermudagrass pastures.  The goal of the study is to determine if the legumes systems are more profitable than the conventional practice of applying synthetic sources of nitrogen.  Results of the two-year grazing study show that the legume systems could not compete economically with the common practice.

The economic feasibility of investing in sprinkler irrigation technology for rice production is investigated using linear programming and capital budgeting to identify the net annual benefits and net present value, respectively.  Groundwater and both flat rate and volumetrically priced surface water sources of irrigation water are analyzed.  Under typical practices occurring in rice production operations in the Texas Rice Belt, sprinkler irrigation technology is not profitable at current water costs.  Producers using volumetrically priced surface water have the greatest incentive to consider sprinkler irrigation, but water prices must increase by over 250 percent for the investment in a sprinkler irrigation system to become attractive.

Economic Significance of Peanut Production and Income to Georgia Farms, Rural Communities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shurley,   W. Donald.
Peanuts accounted for 34 percent of Georgia’s crop income and 13 percent of the State’s total farm income in 1992. The total economic impact of peanut production to the Georgia economy is $1.16 billion annually. Per acre, peanuts provide 2.8 times the debt serving capacity of cotton, 6.1 times that of soybeans and 16.4 times that of corn. The peanut price support and quota program adds economic stability to local economies. The value of peanut quota adds an estimated $48 million to Georgia farmland values, which provides collateral for agricultural lenders. A reduction in peanut prices would adversely reduce farm income and cash-flow, quota values, land values, and the real estate tax base of rural communities. Adverse changes may not alter the comparative...

Economic substitution for US wheat food use by class
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marsh,   Thomas L.
Wheat for food use is conceptualised as an input into flour production and demand is derived from an industry profit function to quantify price responsiveness and economic substitutability across wheat classes. Price and substitution elasticities are estimated for hard red winter, hard red spring, soft red wheat, soft white winter and durum wheat. In general, hard red winter and spring wheat varieties are much more responsive to their own price than are soft wheat varieties and durum wheat. Substitution elasticities indicate that hard red winter and hard red spring wheat are economic substitutes for milling purposes.

The objective of this article is to estimate historical economic surpluses for the subsectors involved in the U.S. sugar market.  Annual producer and consumer surpluses were computed based on a five-equation model and 1958-87 data.  In the last decade, the welfare position of cane- and beet-sugar producers has been roughly maintained, the domestic consumer surplus and the export quasi-rents to foreign countries have both declined, and quasi-rents of the corn-sweetener industry now surpass those that accrue to the cane industry and are about the same as those of the beet-sugar industry.  Some policy implications are discussed.

Economic questionnaires were administered in 1997 and 1998 to farmers in the Indiana/Illinois, Kansas, and Iowa sites involved in the Areawide Pest Management (AWPM) program for the control of corn rootworms.  These questionnaires provided information regarding variable and fixed costs of production for fields located within the management site and also the companion acreage.  The economic analysis indicated that yields, variable costs per acre, and machinery costs per acre were not statistically different within a site across the inner core, outer ring, and companion acreage, with relatively few exceptions.  This gives a solid baseline for a Net Present Value comparison between the soil insecticide and AWPM methods for control of corn rootworms, since...

Autores: Salassi,   Michael E.; Eddleman,   Bobby R.; Hamill,   James G.
This study evaluates the economic survivability of rice farms in the Delta area of Mississippi.  A general whole-farm simulation model, FLIPSIM V, is used to simulate the operations of representative rice farms over a 10-year period.  Although farm size did not change for any of the representative farms considered, the financial structure of these farms changed considerably.  Crop mix was found to cause significant differences in the economic growth and financial viability of rice farms in the region.

Economic Value of Information: Wheat Protein Measurement
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Miao,   Ruiqing; Hennessy,   David A.
In this paper we study U.S. wheat farmers’ willingness to pay for near infrared (NIR) sensor that can segregates wheat grains according to their protein concentration. We first develop a microeconomic optimization model of wheat farmers’ segregating and commingling decisions. Then we use U.S. wheat prices and stocks to estimate a wheat protein stock demand system. This allows us to establish the effects of changes in the protein profile of wheat stocks on protein premiums. The paper’s simulation section combines the results from the microeconomic optimization model and from the econometric estimations to simulate wheat farmers’ WTP for the sorting technology. Preliminary findings from the simulation show that a typical hard red winter (hard red spring)...

ECONOMIC VIABILITY OF BT-CORN IN THE U.S.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kim,   Hong Jin; Konyar,   Kazim; Sargent,   Keith.
Bt-corn, a genetically engineered insect resistant variety, has been adopted by almost one-quarter of all corn farmers, resulting in economic impacts on both conventional corn growers and Bt-corn growers.  we estimate changes in profits for both types of farmers with different levels of seed premiums, yield increases and adoption rates.  We find that Bt-corn growers will see their profits decline when the adoption rate and seed premium are high, if they are not offset by higher yields.  Conventional corn growers will always experience a decline in profits because the yield increase from Bt-corn causes corn price to fall.

Autores: Chand,   Khem; Jangid,   B.L.
Henna (Lawsonia sp.) is a rainfed plantation crop commercially cultivated in Rajasthan on 32,084 ha (2001-02) for its leaves, which are important source of a natural dye. The present study has assessed the profitability and economic viability of henna cultivation based on the data collected from a sample of 100 farmers during 2003-04 in the Pali district of Rajasthan. Based on the factors like net present value, internal rate of return, benefitcost ratio, henna cultivation practised by the farmers has been found to be a financially viable proposition. The financial viability parameters have been found to be more sensitive to changes in prices than cost.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Baker,   Dustin; Young,   Douglas L.; Huggins,   David R.; Pan,   William.
This analysis determines profit maximizing N fertilization levels of hard red spring wheat (HRSW) for various wheat prices, N prices, and protein-based HRSW price premium/discount (P/D) structures for south eastern Washington data.  Fertilizer response data consisting of rates of N fertilization (lb/ac), grain yield (bu/ac), and grain protein (%) were used to statistically estimate regression relationships that predicted yield and protein in response to N.  All predicted net return maximizing N, protein, and yield levels were within the data range.  Increasing P/D incentives for protein increased optimal N, the expected economic result.  At the high P/D structures, the P/D structure dominated N and wheat prices in determining optimal N application levels....

Autores: Marothia,   Dinesh K.; Singh,   R.K.; Chandrakar,   M.R.; Jain,   B.C.
In recent years there has been a serious concern among the farmers, scientists, policymakers and environmentalists regarding the continuous erosion of genetic biodiversity of rice cultivars in Chhattisgarh which has traditionally been known as bowl of scented rices in central India. In view of India’s potential competitiveness in aromatic rices in the international market, it is imperative to understand the dynamics of domestic trade in aromatic rice. In this study, marketing and price-spread patterns of aromatic rice in the state of Chhattisgarh have been examined. A few policy interventions have been suggested for promoting aromatic rices in the state.

Economics, Ecology and GMOs: Sustainability, Precaution and Related Issues
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tisdell,   Clement A.
Ecological, evolutionary and economic issues involved in introducing genetically modified organisms (GMOs), mainly in agriculture, are discussed. The ecological and evolutionary impacts identified hamper (economic) valuation of GMOs and their biosafety regulation and creates difficulties for planning for sustainable development. Assessment of the desirability of releasing GMOs is difficult because of lack of communal agreement about the risks involved, about how much precaution should be exercised given collective risks, and disagreement on the appropriate social criterion to apply. Changes in legal liability are not always economic and cannot eliminate the social conflict generated by GMOs. The economics of developing and marketing GMOs is explored,...

Economics in plant breeding: A case focusing on doubled haploid technology
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pluske,   Johanna M.
With increasing choices in technologies, decision makers responsible for allocating resources in plant breeding programs can benefit from using bioeconomic models. This paper illustrates how such a model works when doubled haploid technology is incorporated into a hypothetical lupin breeding program. The results derived from the model are presented in terms of seed prices required to achieve an 8% return on research. Doubled haploid technology will be used in a breeding program providing the price for seed produced using this technology is less than the seed market price and the estimated price for seed produced using alternative technologies.

Autores: Swinton,   Scott M.; Day,   Esther.
During the past twenty years, economics has played a key role in technology assessment and policy analysis related to integrated pest management (IPM) practices.  The paper reviews economic analysis of IPM as applied to evaluating expected profitability, ex ante and ex post adoption, social welfare impacts, returns to research, and policies that affect pest management generally.  In specific cases, economic methods have contributed significantly to the development of threshold-based IPM decision support software.  Two areas that need greater economic input are assessment of biological pest management practices and the measurement of returns to research in IPM.

Autores: Wachenheim,   Cheryl J.; Black,   J. Roy; Schelegal,   M.L.; Rust,   Steven R.
A framework which permits estimation of economically optimal stocking rates for alternative economic parameters and alfalfa forage availability was developed and applied to a controlled grazing experiment conducted with Holstein steers (243 kg) placed on direct seeded alfalfa pastures in Central Michigan. Responses of ADG to alternative levels of forage availability per standard livestock unit (FA) were summarized by a quadratic function and the associated gains/ha were calculated.  The ADG decreased as standard stocking rate (SSR; SLU/ha) increased except for the combination of the lowest observed SSR and highest FA, where ADG was curvilinear as SSR increased.  The trend for gain/ha was curvilinear for all FA.  The SSR which maximized gain/ha increased...

Economics of Drip Irrigation for Apple Orchards in New York State
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cuykendall,   Charles H.; White,   Gerald B.
In an average growing season in the Northeast, rainfall is somewhat less than is required for optimal performance of fruit crops. The shortage of moisture during critical periods of crop growth and fruit development affects both yields and sizing of produce, thus affecting receipts through both volume of production and average price. Seasons in which moisture is a severe limiting factor affecting profitability occur perhaps two or three years in ten for individual growers in the Northeast. Today's apple growers need investment and cost guidelines to determine the economics of getting trees into production as soon as possible and to avoid periods of drought during the productive life of orchards. Research was undertaken to determine drip irrigation...

Economics of Groundwater Irrigation in Nepal:  Some Farm-Level Evidences
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bhandari,   Humnath; Pandey,   Sushil.
This article examines the economics of groundwater irrigation and shallow tubewell (STW) ownership decision making, using farm-level data collected from 324 households in Nepal.  STW irrigation generated a significant positive effect on rice yield and farmers’ incomes.  Based on a probit model, the farm size, land fragmentation, access to electricity, and access to credit were found to significantly influence farmers’ decisions to own STWs.  Although the water market benefited poor farmers, it is too small and monopolistic.  Policy reforms needed to make groundwater accessible to the poor majority include effective credit programs, investments in rural electrification, and public sector support for promoting suitable pumping technologies

ECONOMICS OF HERBICIDE CONTROL OF LEAFY SPURGE (EUPHORBIA ESULA L.)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bangsund,   Dean A.; Leitch,   Jay A.; Leistritz,   F. Larry.
Leafy spurge (Euphorbia esula L.), a widely established exotic, noxious, perennial weed, is a major threat to the viability of commercial grazing and to beneficial outputs of wildlands in the Upper Great Plains. Herbicide treatments are often recommended based upon measures of physical control rather than on economic criteria. A deterministic, bioeconomic model was developed to evaluate the economic viability of current herbicide control strategies for leafy spurge. Control viability is highly site specific but falls into three categories. First, broadcast herbicide treatment may result in positive net returns for some grazing situations, especially small infestations on highly productive land, in the Upper Great Plains. Second, treating the perimeter to...

Maize is the staple food crop and source of income for majority of the Kenyan population and many sub-Saharan African countries.  The increasing Kenyan population demands an increase in maize production if intermittent food deficits have to be averted.  Since the introduction of improved maize varieties in mid-1960, the start of Green Revolution period, maize yields increased drastically up to 1970s and started declining from 1980’s to-date. The key contributory factors are nutrient mining, sub-optimal input use and insect pest damage. Of the insect pests, stalk borer is of economic importance.  Currently, KARI and CIMMYT are developing maize varieties that are tolerant to stalk borer damage. In order to evaluate the potential impact of these interventions...

This paper develops a management zone delineation procedure based on a spatial statistics approach and evaluates its economic impact for the case of Texas cotton production. With the use of an optimization model that utilizes a yield response function estimated through spatial econometric methods, we found that applying variable N rates based on the management zones delineated would result in higher cotton yields and higher net returns, above Nitrogen cost, relative to uniformly applying a single N rate for the whole field. In addition, a variable rate N application using the delineated management zones produced higher net returns, above Nitrogen cost, relative to a variable N rate system where the zones are based solely on landscape position.

Past research about the efficiency of nitrogen application in winter wheat (Triticum aestivum L.) based on source and timing has produced inconsistent results. The majority of the literature used data from few locations over short time periods. This study used a unique data set of yields and nitrogen quantities from 2002-2009 at ten different locations in Oklahoma, USA. The objective of this research was to determine wheat yield response for granular pre-plant, uniform foliar topdress, and variable rate foliar topdress. Topdress liquid nitrogen had a 19% higher NUE than pre-plant urea, and was the most profitable source of nitrogen.

ECONOMICS OF PRODUCING FOR AN IDENTITY-PRESERVED (IP) GRAIN MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gustafson,   Cole R.
Demand for identity-preserved (IP) crops produced by Northern Plains farmers is increasing.  Buyers are willing to pay a premium for grains that can be guaranteed to possess a unique characteristic.  Several general crop management practices apply to crops raised for IP.  These include greater investment in segregated storage facilities, more meticulous production, isolation, added cleaning/sorting, documentation, greater testing, additional marketing, and risks of liability.  To illustrate, the economics of producing certified seed for sale to other farmers is used as an example of IP grain production.  Many of the concepts and specific practices of certified seed production are applicable to most IP crops raised.

Europe is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all EU Member States. We conduct simulations with the software ArcView® on a GIS dataset of a hypothetical case of GM herbicide tolerant oilseed rape cultivation in Central France. Our findings show that rigid coexistence rules, such as large distance requirements, may impose a severe burden on GM crop production in Europe. These rules are not proportional to the farmers’ basic incentives for coexistence and hence not consistent with the objectives of the European Commission. More alarming, we show that in densely planted areas a domino-effect may occur. This effect raises coexistence costs and even adds to the non-proportionality...

Linear programming model is used to investigate the economic feasibility of utilizing stony lands for crop production in South-Western Quebec where stoniness is the major constraint.  Results for the representative farms indicate that income variations are due to economies of size, differences in crop yields (experimental or farm level) and type of reclamation method used.  The market values for stony lands (determined by regression technique) are higher compared with the productive values.  Analysis also indicates that crop production is feasible within the parameters defined and that it is more economical to develop unutilized stony land rather than purchase prime agricultural land at current market prices.

Autores: Govindasamy,   Ramu; Cochran,   Mark J.; Miller,   David M.; Norman,   Richard J.
This paper identifies optimal combinations of nitrogen in the form of urea, fresh litter and composted litter for rice production.  Traditional cost minimization techniques using data from experimental results conducted at three sites in Arkansas during 1991 have been employed.  Comparisons between different scenarios indicate that the trade-off between the use of poultry litter and urea nitrogen depends on such factors as soil fertility, the yield response to litter application and the relative prices of nitrogen and litter.  The use of litter is more economical at high target yields than at low target yields.

ECONOMICS OF VARIABLE RATE PLANTING FOR CORN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lowenberg-DeBoer,   James.
This analysis works out the economic implications for variable rate seeding of the corn population response curves estimated by Pioneer Hi-Bred agronomists. Examples are developed for various mixes of low, medium and high yield potential soil, as well as for a range of seed costs and variable rate equipment costs. The strategies analyzed were: variable rate planting using agronomic recommendations for each yield potential zone, variable rate planting using an economic decision rule for each yield potential zone, an information strategy which sets the uniform planting rate at the highest population indicated by agronomic recommendations for any part of the field and a second information strategy which uses an economic decision rule for the whole field based...

ECONOMICS OF WHEAT-FALLOW CROPPING SYSTEMS IN WESTERN NORTH DAKOTA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Johnson,   Roger G.; Ali,   Mir B.
Income and risk aspects of wheat-fallow cropping systems are analyzed in western North Dakota.  A wheat yield trend estimation model based on county yields (1950-77) is developed using independent variables of year, annual precipitation, acres of nonfallowed wheat and a dummy variable for fallow and nonfallow practices.  The year-to-year change in wheat yields on fallowed and nonfallowed land indicates that summer fallow is becoming less desirable economically.  Based on 1980 costs and yields, summer fallow maximizes returns to land at low yields, low wheat prices, and high nitrogen prices.  Income variability is reduced under summer fallow.

ECONOMIES OF SCOPE AND SCALE OF MULTI-PRODUCT U.S. CASH GRAIN FARMS: A FLEXIBLE FIXED-COST QUADRATIC (FFCQ) MODEL ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mafoua,   Edouard.
The evidence about the magnitude of scope and scale economies in U.S. cash grain farming is revealed from the empirical estimation of the flexible fixed cost quadratic (FFCQ) model. This framework explicitly disaggregates the crop output vector to take the heterogeneity of output and gives insight to farmers to answer interesting questions such as:  Are three-crop farms more cost efficient than two-crop or single-crop farms?  How important are economies of scope (fixed-cost and variable-cost components) in two-crop farms and three-crop farms?  Two-crop farms as well as three-crop farms exhibit overall economies of scale and scope in all four-size categories that increase with the farm size. They are able to lower the cost of producing crops in the same...

Production costs and economies of size for both conventional tillage and no-till wheat production were determined.  The reduction in the price of glyphosate after the patent expired improved the relative economics of no-till for continuous monoculture winter wheat.  Production costs differ across farm size and by production system.

This paper investigates the relationship between the cost of producing wheat and the size of the wheat enterprise on farms in the Boolooroo Shire of New South Wales. The impact of seasonal variation and new technology on the cost/size relationship is also examined. The estimated longrun cost functions suggest that significant cost economies may be achieved as the area sown to wheat on a farm in the region concerned is increased to approximately 1,000 acres.

Autores: Cullen,   Ross; Takatsuka,   Yuki; Wilson,   Matthew; Wratten,   Steve D.
Researchers have estimated the total economic value of global ecosystem goods and services showing that a significant portion of humanity's economic well being is unaccounted for in conventional GNP accounting (Constanza et al., 1997). To demonstrate this point, authors have conventionally used highly aggregated landscape units for analysis (e.g., biomes), and average, not marginal values, of each ecosystem good or service are estimated for each unit using value transfer methodologies (Wilson et al., 2004). For example, Patterson and Cole (1999a, b) replicated the Constanza et al., (1997) approach by estimating economic values for Waikato and New Zealand ecosystem goods and services associated with standard land cover classes including horticulture,...

Effect of contract farming on productivity and income of small holders: The case of tea production in north-western Vietnam
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Saigenji,   Yoshiko; Zeller,   Manfred.
This paper examines potential of contract farming as a rural development tool by revealing its effect on productivity and income of small holders in tea production in north-western Vietnam. In the present research, three economic analyses are applied. First, the technical efficiency of tea production is estimated by using stochastic frontier model. The results show that contract farming achieved significantly higher technical efficiency compared to non-contract farming. Second, logit model is investigated to determine the influential socio-economic characteristics of households for contract participation. The model indicates that social relationship of households, such as the membership in the communist party, play an important role in contract...

Effect of Cover Crop Adoption on Nitrogen Use among Conventional and Organic Corn Farms – An Empirical Analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chintawar,   Sachin; Gabrielyan,   Gnel; Westra,   John V.
Multiple studies have estimated factors influencing cover crop adoption which include control weed population (Ngouajio et al. 2002), increased soil health (Santhi Wicks and Richard Howitt, 2005), and increased productivity (Johannes M. S. Scholberg, Santiago Dogliotti, Lincoln Zotarelli, Corey M. Cherr, Carolina Leoni and Walter A. H. Rossing, 2010, Jason Bergtold, Jason Fewella, and Patricia Duffy, 2010). An externality of adoption of cover crops that has not been explored is its potential impact on the amount of nitrogen use by farmers. Using a 2009 survey of conventional and organic corn farmers in 7 states of the US, we estimate the factors affecting adoption of cover crops and its impact on nitrogen use. While nitrogen used by farmers is considered...

Effect of Farm-Level Constraints, Existing and Prospective Policies on Expansion of Coconut-Based Intercropping in Sri Lanka
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fernando,   Neil; Edwards,   Ian E.; Thomson,   Kenneth J.; Daw,   Mike.
Coconut-based intercropping (CBI) in Sri Lanka was introduced some 20 years ago to overcome the two main limitations of traditional coconut monocropping, inefficient land use and low incomes to farmers, but it has not been widely adopted. This study analyses the effect of farm-level resource constraints, and government policies on the intensity of adoption of CBI. A multiperiod linear programming (MLP) model was applied for three farmer groups - resource poor, medium endowed, well endowed - categorised using cluster analysis. Data was collected from a survey of randomly selected 113 intercroppers. Empirical results reveal that expansion of CBI is mainly constrained by seasonal labour shortages for all farmer groups, particularly the well endowed, and by...

Effect of Liberalization on Institutional Agricultural Credit Flow and its Relationship with Average Cost of Cultivation in Indian Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Khan,   A.R.; Tewari,   S.K.; Shukla,   A.N.
This paper has examined (i) the nature and extent of inter-state disparities in per hectare flow of short-term institutional credit to agriculture, and (ii) its relationship with average cost of cultivation across states. It has covered all the six regions of the country comprising seventeen agriculturally most important states having about 96 per cent agricultural land in the country. It has revealed that inter-regional disparities in per hectare flow of institutional credit as measured through coefficient of variation (CV) had increased during the pre-liberalization period between 1980-81 and 1990-91. During the post-liberalization era (1991-92 to 2001-02), the inter-regional disparities have reduced. The per hectare institutional credit flow has shown...

Autores: Tumusiime,   Emmanuel; Brorsen,   B. Wade; Biermacher,   Jon T.; Mosali,   Jagadeesh.
Using ammonium based nitrogen fertilizers in crop production has been shown to acidify soils. Lime used to correct soil pH is an important cost to producers. Recommendations of the optimal level of nitrogen to apply typically ignore the cost of lime created by nitrogen fertilization. This study was aimed to estimate soil pH change in response to nitrogen and lime application, and determine the effect of considering the cost of lime on recommendations about the optimal level of nitrogen. Yield response and pH functions were estimated and used to determine optimal levels of inputs. The effect of the cost of lime on recommendations about the optimal level of nitrogen was found to be marginal. Nitrogen acidification was found to be more severe with nitrogen...

Effect of Prices, Traits and Market Structure on Corn Seeding Density
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mitchell,   Paul D.; Shi,   Guanming; Ma,   Xingliang; Lauer,   Joseph G.
Recent agronomic research finds that economically optimal seeding densities have likely increased for many Midwestern corn farmers as a result of genetic improvements including new GM traits such as Bt corn and herbicide tolerance.  We derive a per acre demand model for hybrid seed corn to examine the determinants of corn seeding densities and estimate the model using a large data set of individual farmer seed corn purchases.  Current results identify factors other than prices affecting farmer corn seeding densities.  Among these factors are the GM trait of the seed corn, measures of the local seed corn market structure, seed purchase source and intended end use.  We interpret these effects in terms of information effects—farmers with more/better access to...

EFFECT OF PROPOSED GRAIN STANDARDS ON MARKETING COSTS OF THE U.S. SORGHUM SECTOR: AN INTERREGIONAL TRANSSHIPMENT-PLANT LOCATION MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ziari,   Houshmand A.; Fuller,   Stephen W.; Grant,   Warren R.; Sutaria,   Vinod.
Recent legislative initiatives call for studies to evaluate costs associated with cleaning U.S. grains to meet more stringent standards. This paper reports on a study which developed a mixed-integer programming model of the U.S. sorghum sector to (1) determine the least-cost geographic location for new cleaning investment at the country, terminal and port elevator stages of the marketing system and (2) measure additional system marketing costs associated with implementing the proposed standards. Results show the least-cost cleaning location to be at country and terminal elevators in excess supply regions. Implementing the proposed standard would increase system costs about 2 percent.

EFFECT OF UNCERTAINTY ON FARMERS DECISION MAKING: CASE OF ANIMAL MANURE USE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bert,   Vermeire; Jacques,   Viaene; Xavier,   Gellynck.
The negative effects of uncertainty and on perceived absorptive capacity indicates that identified problems with respect to the use of animal manures do not motivate farmers to search for external knowledge in order to solve these problems but, in contrary, they will be less inclined to learn about better ways to make use of manure. Furthermore, this will make them also less satisfied about the external knowledge which is offered and particularly will make them less willing to invest in soil analysis techniques which could help them to develop a more reliable nutrient management. These conclusions are problematic for policy makers, counsellors and consultants. First of all, while uncertainty could lead to problem identification and start a learning process...

Perceptions are known to play an important role in the innovation adoption decision. Once influential perceptions have been identified, there is the potential for information to influence adoption by changing these perceptions. In this paper, the influence of an extension workshop targeting grain growers’ perceptions known to be associated with the adoption of integrated weed management and herbicide resistance management has been measured using regression analysis. Consistent with a Bayesian learning framework, the greatest influence on grower perceptions and intended adoption behaviour was observed where information could be delivered with a high degree of certainty and validity.

This paper studies the dynamics between cash cropping and food crop productivity in Gokwe North District in Zimbabwe, a major cotton producing area. The main research issues were: (1) to identify the determinants of commercialized crop production at the household level; and (2) to determine the effect of increasing crop commercialization on household food productivity. The paper derives a household crop commercialization index, defined as the ratio of crop sales to total crop production. Econometric models were developed for identifying the determinants of household-level commercialization and for measuring its effects on food crop productivity.

The objectives of this paper are to determine the effects of NCPB maize trading activity and the maize import tariff on wholesale maize market price levels and volatility. The analysis uses monthly maize price and trade data covering the period January 1990 to September 2004. Results are based on a vector autoregression (VAR) approach that allows estimation of a counterfactual set of maize prices that would have occurred over the 1990-2004 period had the NCPB not existed and trade restrictions been removed. Assessed are the separate impacts of policy on wholesale prices in Kitale, a major surplus-producing area, and Nairobi, the major urban demand center in the country.

A replicated, small plot study on watermelon [Citrullus lanatus (Thunberg) Matsumura and Nakai] in 1997, 1999, and 2000 revealed that production management intensity affected yields and profitability of watermelon, in Oklahoma.  Management intensity was based on a combination of cultural practices and levels of use of production methods.  Low intensity management (LM) consisted of use of soil fertilization and weed control.  High intensity management (HM) included the same weed control and fertilization as LM but also included use of plastic mulch, drip irrigation, insect pest control, and plant disease control.  Cost and return analyses were based on the range of actual prices during the cropping season and the range of yields during the three years....

Effects of Marketing Loans on U.S. Dry Peas and Lentils:  Supply Response and World Trade
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lin,   William W.; Lucier,   Gary.
The 2002 Farm Act required USDA to implement marketing loans for the 2002-07 crops of dry peas, lentils, and small chickpeas. This provision led to expanded acreage for dry peas and lentils, crops analyzed in this study. The analysis found that marketing loans played a role in expansion for dry peas in 2003-05 and for lentils in 2003. For dry peas and lentils, marketing loans contributed to acreage expansion in North Dakota and Montana. Simulation model results suggest that marketing loans had negligible impacts on world prices for dry peas and lentils in 2003-05. Impacts on U.S. exports were minor, increasing by about 2 percent in 2003.

Effects of participation in organic markets and farmer-based organizations on adoption of soil conservation practices among small-scale farmers in Honduras
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wollni,   Meike; Lee,   David R.; Thies,   Janice E.
Conservation agriculture is often perceived to provide “win-win” outcomes for farmers leading to reduced erosion and off-site sedimentation, as well as improved soil fertility and productivity. However, adoption rates for conservation agriculture in many regions of the world remain below expected levels. This paper looks at the effect of organic markets in providing incentives for farmers to adopt soil conservation practices based on the willingness of consumers to pay a price premium for the use of sustainable production technologies. Farmer-based organizations may help farmers overcome information deficiencies with respect to production processes as well as consumer preferences. Based on original survey data from 241 small-scale farm households in...

Effects of Price Volatility and Surging South American Soybean Production on Short-run Soybean Basis Dynamics
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zhang,   Rui (Carolyn); Houston,   Jack E.
This study investigates the effects of South American production (SAP) and futures volatility on the soybean price dynamics in terms of their effects on the basis. The results of the econometric model showed that both South American production and futures volatility of the nearby contract have negative effects on the basis though in the forecast model, lagged values of these two factors failed to predict basis change in the future. If information about the change of the expected SAP or futures volatility is available, then the model can predict the changes in basis. This information would be helpful for hedgers to decide the time to lift their hedge.

EFFECTS OF QUALITY CONSIDERATIONS AND CLIMATE/WEATHER INFORMATION ON THE MANAGEMENT AND PROFITABILITY OF COTTON PRODUCTION IN THE TEXAS HIGH PLAINS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Britt,   Megan L.; Ramirez,   Octavio A.; Carpio,   Carlos E.
Production function models for cotton lint yields, seed yields, turnout, and lint quality characteristics are developed for the Texas High Plains.  They are used to evaluate the impacts of quality considerations and of climate/weather information on the management decisions and on the profitability and risk of irrigated cotton production systems.  It is concluded that both quality considerations and improved climatic/weather information could have substantial effects on expected profitability and risk.  These effects mainly occur because of changes in optimal variety selection an irrigation water use levels.  Quality considerations in particular result in significantly lower irrigation water use levels regardless of the climate/weather information...

EFFECTS OF RISK, DISEASE, AND NITROGEN SOURCE ON OPTIMAL NITROGEN FERTILIZATION RATES IN WINTER WHEAT PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Howard,   Donald D.; English,   Burton C.; Larson,   James A.; Roberts,   Roland K.; Walters,   Jeremy T.
Interactions among nitrogen (N) fertilization rate, N source, and disease severity can affect mean yield and yield variance in conservation tillage wheat production.  A Just-Pope model was used to evaluate the effects of N rate, N source, and disease on the spring N-fertilization decision.  Ammonium nitrate (AN) was the utility-maximizing N source regardless of risk preferences.  The net-return-maximizing AN rate was 92 lb N/acre, providing $0.52/acre higher net returns than the best alternative N source (urea).  If a farmer could anticipate a higher than average Take-All infection, the difference in optimal net-returns between AN and urea would increase to $35.11/acre.

Effects of Site-Specific Management on the Application of Agricultural Inputs
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hennessy,   David A.; Babcock,   Bruce A.; Fiez,   Timothy E.
Site-specific management of inputs in agricultural production is receiving increasing attention because of new technologies and concerns about excessive input use. This paper provides a microeconomic analysis of its implications. It shows that profit decreases with an increase in the variability of input requirements, but that the input and production effects can be quite complicated. The effects of moving from uncertainty about input requirements to variable requirements are also identified. An empirical study of nitrogen fertilization suggests that sitespecific management may reduce input use substantially, but the production and profitability impacts may not be large.

Effects of Socio-Institutional and Emotional Factors of Japanese Farmland Rental Transactions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kunimitsu,   Yoji.
Farmland reallocation between farmers through rental transactions is critical for improving Japanese rice productivity.  This study examined effects of socio-institutional and emotional factors as well as economic factors on rental transactions.  A stochastic choice model was applied to contingent valuation data by considering regional heteroscedasticity.  Empirical results showed (1) existence of economic inefficiencies, 3% loss of economic surplus due to socio-institutional restriction, which is probably reflected in transaction costs; (2) a 15% reduction in surplus due to emotional reluctance of farmers; and (3) strong influences of rice price, wages, and geographical location on the rental rate and agreement level.

Effects of Soybean Checkoff Research Expenditures on U.S. Soybean Yields and Net Revenue: A Time Series Analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bessler,   David A.
Statistical methods are used to study relationships between research expenditures (adjusted for inflation) made from producer checkoff programs and soybean yields and net revenues in the United States for the years 1978 – 2007. Results presented are for yield and net revenue data and research expenditures for the entire United States. We find that research expenditures over the years 1994 to 2007 are responsible for a 0.95 bushel per acre per year increase in soybean yields. We calculate net producer revenues to be about $17 per acre higher than would have been the case without the soybean research checkoff expenditures.

Autores: Duffy,   Patricia A.; Cain,   Danny L.; Young,   George J.; Wetzstein,   Michael E.
Five-year, 0-1 mixed integer programming models of two representative Alabama farms were developed for analyzing the effects of the Boll Weevil Eradication (BWE) program on farm program participation and crop-mix decisions by Alabama cotton farmers. In previous research the BWE program was found to increase yields by approximately 100 pounds per acre in Georgia and southern Alabama where the program has been in effect for several years. In this study, these increased yields are shown to be an important factor contributing to the expanded cotton acreage in southern Alabama. For northern Alabama, gains to producers are also possible, but not to the extent realized in the southern part of the state.

The practices of the Canadian Wheat Board (CWB) are an important issue in U.S. - Canada trade disputes and WTO negotiations.  This study analyzes the CWB?s effect on U.S. producers by reviewing findings from previous research and developing models to analyze CWB wheat exports to the United States and the competitive structure of Canadian wheat exports in the world market.  U.S. grain producers could benefit from the removal of the CWB as the United States could become more competitive in export markets.  However, elimination of the CWB could also result in an increase in Canadian wheat exports to the United States as Canadian producers near the border could sell directly to the United States to take advantage of market opportunities.  The net effect is...

Effects of the GM Controversy on Iowa Corn-Soybean Farmers' Acreage Allocation Decisions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Alexander,   Corinne E.; Fernandez-Cornejo,   Jorge; Goodhue,   Rachael E.
Prior to the 2000 planting season, some industry observers predicted acreage of genetically modified crops would decline dramatically. However, actual 2000 plantings presented a puzzle. Farmers reduced their acreage of genetically modified corn, but concurrently increased their acreage of genetically modified soybeans. We demonstrate that it may be theoretically optimal for risk-averse farmers to reduce their corn acreage but not their soybean acreage. However, past experience, attitudes, and farm size explained planting decisions to a larger degree than did risk preferences.

Efficiency and Pooling in Western Cape Wine Grape Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Conradie,   Beatrice; Cookson,   Graham; Thirtle,   Colin G.
This paper uses a stochastic frontier and inefficiency model to test the efficiency of grape production in the Western Cape. The data covers two panels of wine grape farms (34 in Robertson and 36 in Worcester) for 2003 and 2004 and 37 table grape farms in De Doorns for 2004 only. Tests show that Cobb Douglas stochastic production frontiers, with variables to explain the inefficiencies are an appropriate representation of the five individual samples. The stochastic frontier results indicate that output can be explained by land, labour and machinery and that efficiency cab be affected by labour quality, age and education of the farmer, location, the percentage of non-bearing vines and expenditures on electricity for irrigation. These data is sufficiently...

This study contributes to the agricultural productivity literature in developing countries and Nigeria especially by quantifying the level of efficiency for sample of rice farmers from North Central Zone of Nigeria. A stochastic efficiency decomposition frontier analysis was used to derive technical efficiency measures separately for rice under two production systems (upland and lowland systems). Average economic efficiency of 51.9 % and 55.4 % found for up land and lowland rice farmers respectively suggests that there is room for productivity gain for farms in the sample through better use of available resources given the state of technology. Gains in productivity growth have become increasingly important to Nigerians as demand for rice continue to...

Autores: Fogarasi,   Jozsef.
This paper analyses efficiency and total factor productivity (TFP) in Hungarian sugar beet production applying non-parametric frontier techniques. For 2004 and 2005 efficiency and TFP are calculated by Data Envelopment Analysis (DEA) and by a Malmquist index respectively. Between 2004 and 2005 the average technical efficiency was very stable, around 0.80 for CRS efficiency and 0.87 for VRS efficiency, suggesting that in both years farms were similarly clustered towards the frontier. The analysis of returns to scale reveals that during both years half (48%) of the sugar beet growers were operating under increasing returns to scale. In the two analysed years changes occurred between decreasing returns to scale and scale efficient farms, when the first...

Efficiency of selected risk management instruments. An empirical analysis of risk reduction in Kazakhstani crop production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Heidelbach,   Olaf.
Kazakhstan’s agricultural sector plays an important role in the country's economy. Not only does it function as an economic output producer, it also serves as a social buffer in times of transition to a market economy. The restructuring process had a strong impact on the economic performance of agricultural enterprises. As the state no longer functions as a back-up financier in times of economic downturn, farmers have to find their own sustainable instruments to manage business risks, which are significant in Kazakhstan due to the acute continental climate and the resulting revenue fluctuations. This thesis is an integral part of the research project "Crop Insurance in Kazakhstan – Options for Building a Sound, Institution Promoting Agricultural...

Efficiency of Selected Risk Management Instruments - An Empirical Analysis of Risk Reduction in Kazakhstani Crop Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Heidelbach,   Olaf.
Recent academic discussion regarding crop insurance in developing and transition countries has focused on weather index insurance. But empirical analyses of such schemes based on farm level data cannot be found in the literature, though this insurance type shows clear advantages compared to multiple-peril crop insurance and revenue insurance. Recent empirical applications of risk and stochastic programming models focus on the optimisation of production planning, while literature on the effects of crop insurance on the farm level mainly focuses on the empirical investigation of reductions in farm income variance. The novelty of this paper is that it integrates regionally-adapted insurance products and expert-evaluated technology choices into a programming...

This paper assesses the technical efficiency of paddy production in one of the major irrigation schemes in Sri Lanka with special emphasis on the usage of agrochemical inputs and determinants of technical efficiency. The presence of technical inefficiency and its causality is investigated using a stochastic production frontier model. Data for the estimation was gathered from a farm household survey covering 225 households across five administrative units from 3 irrigation blocks for the cultivation season 2003/2004. The results of the production function show negative relationships between yield and the cost of pesticides indicating an over use of pesticides. The average technical efficiency was estimated to be 0.37. Among the determinants of inefficiency...

EFFICIENCY OF WIND INDEXED TYPHOON INSURANCE FOR RICE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Banerjee,   Chirantan; Berg,   Ernst.
Index-based weather insurances are innovative tools for mitigating weather risks in agriculture. Several donor agencies and development organisations are investing substantially to propagate these programmes in developing countries. However, often due to high basis risks, these products mitigate risk only through diversification effect, thereby defeating the intended purpose. Besides, they send confusing messages to the farmers regarding the very concept of insurance. Therefore, this paper investigates the efficiency of two such index-based weather insurances in Philippines, designed to mitigate rice yield loss caused by strong typhoon winds. The insurance products are designed assuming negative linear correlation between wind speed and rice yield. To...

Efficient Use of Superphosphate in the Pasture Programme
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McFarlane,   J.D.
Phosphate deficiency is very marked in Australian soils, particularly in the southern half of the continent. The annual usage of superphosphate in Australia is just over two millions tons, approximately 65 per cent of which is applied to pastures. Each year, therefore, landholders are spending something like £40 million on the purchase, transportation and application of this fertilizer.  The present considerations refer mainly to the use of superphosphate on pastures in the higher rainfall sheep areas, where there are very extensive areas of low fertility soils in climatic zones favourable for the growth of various introduced pasture species. In such areas, particularly during the last ten years, many landholders have used substantial quantities of...

This paper has sought to evaluate the economical efficiency in the use of productive resources in the coffee production in the south region of the state of Minas Gerais. Economical efficiency was estimated through a production frontier function using a sample of 43 coffee producers. The average economical efficiency index reached by the coffee producers in the south of Minas Gerais was 80,14%. Such index indicates that a tendency to gains in productions can be obtained through a better allocation of the production factors, which may lead them to operate on the production frontier line.

Autores: Shah,   Samarth; Brorsen,   B. Wade.
This study compares liquidity costs of electronic and open-outcry wheat futures contracts traded side-by-side on the Kansas City Board of Trade. Liquidity costs are considerably lower in the electronic market. Liquidity costs in the electronic market are still considerably lower after eliminating the bias created by splitting orders in the electronic market. Price volatility and transaction size are positively related to liquidity costs, while a negative relation is found between daily volume and liquidity costs. Price clustering at whole cent prices occurs in the open-outcry market which helps explain its higher liquidity costs. Daily volumes were distinctively higher during the Goldman-Sachs roll, but not enough to explain the higher liquidity costs in...

The aim of this research is to establish the persistence of annual crop yield point values subjective estimates, and the coherence and reliability of subjective crop yield probability density functions (PDF) elicited from a series of interviews carried out on a wide group of farmers, and then to determine whether they should be included or not in a decision support system (DSS). Three different elicitation techniques were used: a) The Two Step PDF estimation method b) Triangular distribution c) Beta distribution Although the results are noteworthy, further studies should be carried out to perfect the aforementioned techniques before crop yield PDF's are used in decision making processes.

ELICITING AND VALUING MARKET PREFERENCES WITH TRADITIONAL FOOD CROPS: THE CASE OF CHICKPEA IN INDIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Agbola,   Frank W.; Kelley,   Timothy G.; Bent,   Martin J.M.; Rao,   P. Parthasarathy.
During the past decade the Indian chickpea industry underwent a dramatic structural shift following the implementation of market-oriented policies by the Government of India.  This paper examines consumer attitudes to quality characteristics of chickpea in India.  A linear hedonic price model is estimated using auction price and quality data of chickpea samples obtained from major markets in India.  Empirical results indicate that specific physical quality characteristics and purity standards are important factors influencing the price of chickpea in India.  Thus, there may be an incentive for domestic producers and sellers of chickpea – and exporting countries – to improve the quality of their product, if improvements in specific physical characteristics...

Eighty-nine percent of American households were food secure throughout the entire year in 2005, meaning that they had access, at all times, to enough food for an active, healthy life for all household members. The remaining households were food insecure at least some time during that year. The prevalence of food insecurity declined from 11.9 percent of households in 2004 to 11.0 percent in 2005, while the prevalence of very low food security remained unchanged at 3.9 percent. This report, based on data from the December 2005 food security survey, provides the most recent statistics on the food security of U.S. households, as well as on how much they spent for food and the extent to which food-insecure households participated in Federal and community food...

Consumer demand for organic products has widened over the last decade. While new producers have emerged to help meet demand, market participants report that a supply squeeze is constraining growth for both individual firms and the organic sector overall. Partly in response to shortages in organic supply, Congress in 2008 included provisions in the Food, Conservation, and Energy Act (2008 Farm Act) that, for the first time, provide financial support to farmers to convert to organic production. This report examines recent economic research on the adoption of organic farming systems, organic production costs and returns, and market conditions to gain a better understanding of the organic supply squeeze and other emerging issues in this rapidly changing...

Empirical Confidence Intervals for WASDE Forecasts of Corn, Soybean and Wheat Prices
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Isengildina,   Olga; Irwin,   Scott H.; Good,   Darrel L.
This study suggests that confidence intervals for WASDE forecasts of corn, soybean, and wheat prices may be improved if they are estimated using an empirical approach.  Empirical confidence intervals are calculated following Williams and Goodman's (1971) method and use historical forecast errors to estimate forecast error distributions which is then used to predict confidence limits for future forecast errors.  Three procedures for empirical distribution estimation are compared: 1) histogram, 2) changing distribution, 3) fixed distribution.  The results suggest that the fixed distribution approach using logistic distribution provided accurate confidence intervals for WASDE corn, soybean, and wheat price forecasts.

EMPIRICAL COST FUNCTIONS FOR LABOUR-INTENSIVE PADDY FARMS IN FORMOSA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lin,   An-Yhi; Heady,   Earl O.
This study includes an estimate of cost functions for paddy farms in Formosa. Two types of estimational techniques are used; namely regression estimates and synthesized or budgeted cost curves. Long-run and short-run regression-derived curves are estimated for rice and sweet potato farms from samples which provide the observations. Estimates are for total cost functions with average cost functions computed per hectare. From sample observations, it was possible to derive, through regression estimates, only linear total cost functions. The non-linear average cost functions have only slight (economically unimportant) slopes beyond 2•-5 hectares. Hence, large farms do not seem to be an important policy imperative. However, the steep slope of the average cost...

Autores: Wilson,   Clevo.
Willingness to pay models have shown the theoretical relationships between the contingent valuation, cost of illness and the avertive behaviour approaches.  In this paper, field survey data are used to compare the relationships between these three approaches and to demonstrate that contingent valuation bids exceed the sum of cost of illness and the avertive behaviour approach estimates. The estimates provide a validity check for CV bids and further support the claim that contingent valuation studies are theoretically consistent.

Latest developments in investment analysis offer a number of valuable insights into how to evaluate investment opportunities encountering the weaknesses of net present value criterion. More specific, irreversibility, uncertainty and the choice of timing are conditions that net present value does not include but they alter the investment decision in critical way. Employing contingent claims analysis in tangible investments several assumptions made by discount cash flow method are concerned and better assessment results can be derived. In this work, an attempt is made to apply real options methodology in agricultural investments.

ENDOGENOUS PROTECTION IN THE MEXICAN CORN AND SORGHUM MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marshall,   Maria I.; Marsh,   Thomas L.
Trade relations between the United States (U.S) and Mexico are increasingly interrelated and important ever since the ratification of NAFTA in 1994.  With the advent of NAFTA, tariffs on many agricultural products were lowered or are in the process of being lowered.  Mexico implements a tariff-rate quota for corn which is to be phased out by 2009.  This quota is divided among the various Mexican corn importers with "cupos", which are import permits.   Import permits are administrative trade barriers that can be defined as any obstacle that appears and disappears as market conditions change.  It is widely recognized in the literature that administrative trade barriers create numerous obstacles to the international exchange of agricultural products.  In this...

Energy Crop Production Costs and Breakeven Prices Under Minnesota Conditions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lazarus,   William F.
Production costs and breakeven prices were calculated for four energy crops plus corn stover.  The energy crop breakeven prices were calculated under two different scenarios regarding land costs and the opportunity costs of not utilizing the land for some other competing land use.  One scenario is that the competing land use is pasture.  The other is that the energy crops would compete with grain crops on more expensive land, and would need to provide a return over land costs equal to returns on the grain crops.   Corn stover would be the cheapest of the energy biomass sources considered, at $50/ton to cover the additional machinery costs to shred, rake, bale, and transport 25 miles to a processing plant.  Aside from stover, a grassland crop under high...

Energy Crop Supply in France: A Min-Max Regret Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kazakci,   Akin; Rozakis,   Stelios.
This paper attempts to estimate energy crop supply using an LP model comprising hundreds of representative farms of the arable cropping sector in France. In order to enhance the predictive ability of such a model and to provide an analytical tool useful to policy makers, interval linear programming (ILP) is used to formalise bounded rationality conditions. In the presence of uncertainty related to yields and prices it is assumed that the farmer minimises the distance from optimality once uncertainty resolves introducing an alternative criterion to the classic profit maximisation rationale. Model validation based on observed activity levels suggests that about 40% of the farms adopt the min-max regret criterion. Then energy crop supply curves, generated by...

Increasing worldwide energy demand and diminishing supplies of fossil fuels have necessitated the development and increasing use of new sustainable energy sources, as well as more parsimonious energy use. In the context of agriculture, research has focused predominantly on the production of bio-energy, while only a limited number of studies have investigated the energy use and possible energy saving in conventional agricultural production. In response to this lack in empirical research this study aims (i) to measure the farm-level energy and cost efficiency of conventional agricultural (wheat) production, (ii) to identify the potential for energy saving in conventional agriculture and quantify its shadow cost, (iii) to identify production technologies and...

Autores: Nalley,   Lawton Lanier; Barkely,   Andrew; Watkins,   Brad; Hignight,   Jeffrey A.
This study applies portfolio theory to rice varietal selection decisions to find profit maximizing and risk minimizing outcomes. Results based on data from six counties in the Arkansas Delta for the period 1999–2006 suggest that sowing a portfolio of rice varieties could have increased profits from 3 to 26% (depending on the location) for rice producers in the Arkansas Delta. The major implication of this research is that data and statistical tools are available for rice producers to improve the choice of rice varieties to plant each year in specific locations. Specifically, there are large potential gains from combining varieties that are characterized by inverse yield responses to growing conditions such as drought, pest infestation, or the presence of a...

Agriculture in India occupies an important place as it contributes nearly 25 per cent of GDP and two-thirds of the population depend upon it. Agricultural growth in the past has been sufficient to move from severe food crisis to aggregate food surplus today. The rainfed regions are diverse in terms of resource base, varying from resource rich regions harnessing substantial production to resource poor regions with restricted potential. These resource poor regions are mostly dominated by secondary crops. Barring maize and potato, secondary crops are loosing ground against the finer cereals, cash and commercial crops. Therefore, there is an urgent need to provide a leverage to these crops by providing support in terms of technological advancement and policy...

Top Agro (TA - not its real name) is a small crop protection start-up operating in the European Union. In a relatively short period of time TA has been able to secure a reasonable profit margin and build a solid niche in the Italian crop protection market. The driving force in their success is the professional expertise of the two owners, their knowledge of the domestic market, and the highly flexible business model they’ve developed. Chemicals are sourced either in the Far East via a Hong Kong based commercial partner or purchased directly from other European domestic suppliers. TA is responsible for the formulation and packaging of the finished product, which is then distributed in the domestic Italian market. Although TA is now profitable, further sales...

Autores: Goncharova,   Natalia V.; Oskam,   Arie J.
The entry and exit decisions, considered as investment decisions, are investigated in the paper. Taking into account the heterogeneity of entry and exit, the analysis is based on two types of entry-exit: real (related to the establishment or closing of a firm), or entry-exit in a new sector (indicating the diversification or changing specialisation). The theoretical model is based on Marshallian trigger points with Real Option trigger points as an alternative. The estimation exploited the negative binomial model to investigate the role of trigger points (thresholds) on the observed number of entry or exit firms in Dutch glasshouse horticulture over 25 years. Firms should overcome different thresholds depending on types of entry and exit. Marshallian...

ENTWICKLUNG DES TSCHECHISCHEN ZUCKERSEKTORS SEIT 1989
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bavorova,   Miroslava.
The breakdown of the planned economy in the Czech Republic induced many changes for the Czech sugar industry. Successful restructuring should foster competitiveness of sugar production and processing. Another target of the sugar sector is its preparation for EU-accession by adjusting to EU market regulations. Consequently, the liberal sugar market policy which was introduced shortly after 1989 was transferred into a system with price and quantity control. Today, this policy differs only in degree from EU market policy. The processes of privatization, restructuring and modernization have been conducted successfully in the nineties. International investors made significant contributions, especially by investing in sugar processing. Despite of a favorable...

Environmental and Economic Impact Assessments of Environmental Regulations for the Agriculture Sector: A Case Study of Potato Farming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Craven,   Ian.
A multi-year research study was established under the environmental pillar of the Agriculture Policy Framework (APF) to evaluate the role and impact of existing farm level environmental regulations administered by local, provincial, federal governments. The Phase 1 study entitled  "Inventory and Methodology for Assessing the Impacts of Environmental Regulations in the Agricultural Sector" was released in March 2006 on AAFC online.  There is a growing concern about the impact and effectiveness of environmental regulations, specifically impact on the competitiveness of primary agriculture. Empirical analysis is required to better understand the exact role that agri-environmental regulations play in determining a farm's cost structure and to compare...

Environmental Benefits from Reduced Pesticide Use and Returns to Research: An Application to the U.S. Cotton Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sande,   Doris N.; Mullen,   Jeffrey D.; Matekole,   Augustus N.
Cotton production is one of the main pesticide use industries in the U.S. This intensive use has resulted in the disruption of naturally occurring biological control factors that regulate other insect pest populations and “the pesticide treadmill”. The result is resistance to insecticides, high control costs and unacceptable levels of chemical insecticides in the environment. Concerns about the environmental and human health effects from pesticide use thus need to be modeled in evaluation studies.

Environmental Indices for the Chinese Grain Sector
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chen,   Ming; Karp,   Larry S.
Increased population pressure and political decisions have led to more intensive agricultural practices in China. As in other regions of the world, these practices can damage natural capital We use the Kalman filter and Chinese panel data to estimate an index of environmental productivity (natural capital), together with the parameters of environmental dynamics and the production function. These estimates show that intensive practices are likely to have had persistent, substantial, and statistically significant negative effects on productivity. Ignoring these effects can cause substantial misallocation of resources. The results illustrate the possibility of estimating sectoral environmental indices using data commonly available.

Environmental protection of agriculture -clash of policies?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Helin,   Janne.
Agricultural primary production is extensively influenced by policies and regulation. On the level of European Union the common agricultural policy (CAP), frames the production environment. This study analyses the conflict of environmental and income policies in the context of CAP reform, eutrophication, the Water Framework Directive and Finnish policies. As targets of the policies do not coincide and often conflict, the environmental problems of farming have not been solved in the past decades. The comparative analysis is conducted quantitatively under static non-linear optimisation framework of representative farms of cereal and milk production regions of Finland. The results indicate that the decoupling of subsidies from production has enabled more...

We estimate a farm-level cost function for Belgian crop farms using FADN data over the study period 1996-2006. We rely on an estimation of farmers' expected yields at the time cropping decisions are made rather than actual yields observed in the FADN data. The use of an ex ante cost function improves the cost function estimation. We subsequently suggest how our cost function can be used in simulations to analyze farmer response to changes in output price risk.

ESTIMATING CORN YIELD RESPONSE MODELS TO PREDICT IMPACTS OF CLIMATE CHANGE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dixon,   Bruce L.; Hollinger,   Steven E.; Garcia,   Philip; Tirupattur,   Viswanath.
Projections of the impacts of climate change on agriculture require flexible and accurate yield response models.  Typically, estimated yield response models have used fixed calendar intervals to measure weather variables and omitted observations on solar radiation, an essential determinant of crop yield.  A corn yield response model for Illinois crop reporting districts is estimated using field data.  Weather variables are time to crop growth stages to allow use of the model if climate change shifts dates of the crop growing season.  Solar radiation is included.  Results show this model is superior to conventionally specified models in explaining yield variation in Illinois corn.

Estimating Cotton Harvest Cost per Acre When Harvest Days are Stochastic
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Farrell,   Matthew; Ibendahl,   Gregory A.
The cotton harvesting industry is in the beginnings of its next technological advance, cotton harvesters that form cotton modules inside the machine then deposit them off the rows. These new machines eliminate the need for extra labor and equipment, but are more expensive than conventional pickers. Increased field efficiency is also a benefit of the on-board module builders. The problem facing producers is determining the optimal number of acres to plan for harvest when trying to decide which harvester to purchase.  This paper examines two objectives. First, determine the cost per acre of both conventional and on-board module harvester systems for different acreage levels assuming harvest hours per year are fixed. Second, make the harvest hours per season...

ESTIMATING INSECTICIDE APPLICATION FREQUENCIES: A COMPARISON OF GEOMETRIC AND OTHER COUNT DATA MODELS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hubbell,   Bryan J.
The number of insecticide applications made by an apple grower to control an insect infestation is modeled as a geometric random variable.  Insecticide efficacy, rate per application, month of treatment, and method of application all have significant impacts on the expected number of applications.  The number of applications to control a given insect population is dependent on the probability of achieving successful control with a given application.  Results suggest that northeastern growers have the highest and mid-Atlantic growers the lowest probability of controlling an infestation with a given application.  Results also indicate that scales require the least and moths the most number of applications.  Growers are not responsive to per unit insecticide...

Estimating Non-linear Weather Impacts on Corn Yield—A Bayesian Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Yu,   Tian; Babcock,   Bruce A.
We estimate impacts of rainfall and temperature on corn yields by fitting a linear spline model with endogenous thresholds. Using Gibbs sampling and the Metropolis - Hastings algorithm, we simultaneously estimate the thresholds and other model parameters. A hierarchical structure is applied to capture county-specific factors determining corn yields. Results indicate that impacts of both rainfall and temperature are nonlinear and asymmetric in most states. Yield is concave in both weather variables. Corn yield decreases significantly when temperature increases beyond a certain threshold, and when the amount of rainfall decreases below a certain threshold. Flooding is another source of yield loss in some states. A moderate amount of heat is beneficial to...

Using a stochastic version of the POLYSYS modeling framework, an examination of projected variability in agricultural prices, supply, demand, stocks, and incomes is conducted for corn, wheat, soybeans, and cotton during the 1998-2006 period. Increased planting flexibility introduced in the 1996 farm bill results in projections of significantly higher planted acreage variability compared to recent historical levels. Variability of ending stocks and stock-to-use ratios is projected to be higher for corn and soybeans and lower for wheat and cotton compared to the 1986-96 period. Significantly higher variability is projected for corn prices, with wheat and soybean prices also being more variable. No significant change in cotton price variability is projected.

A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

ESTIMATING SITE-SPECIFIC NITROGEN CROP RESPONSE FUNCTIONS: A CONCEPTUAL FRAMEWORK AND GEOSTATISTICAL MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Malzer,   Gary L.; Hurley,   Terrance M.; Kilian,   Bernard.
Confirming the precision agriculture hypothesis for variable rate nitrogen applications (VRA) is challenging.  To confront this challenge, researchers have used increasingly sophisticated statistical models to estimate and compare site-specific crop response functions (SSCRFs).  While progress has been made, it has been hampered by the lack of a conceptual framework to guide the development of appropriate statistical models.  This paper provides such a framework and demonstrates its utility by developing a heteroscedastic, fixed and random effects, geostatistical model to test if VRA can increase nitrogen returns.  The novelty of the model is the inclusion of site, spatial, treatment, and treatment strip heteroscedasticity and correlation.  Applied to data...

In this study, we estimate an output distance function in the context of a multi-output and multi-input production technology by stochastic frontier techniques. Unbalanced panel data for smallholder farms that grown cassava and other crops in Southwestern Nigeria covering 2006/07 to 2008/09 farming seasons is used for the analysis. The results show that the marginal rate of transformation (MRT) between “other crops” grown by the farmers and cassava produced relative to the output mix is negative and significantly different from zero. We observed also that increasing returns-to-scale as well as technical progress characterized cassava production in the region. Furthermore, fertilizer and pesticides are found to have significant substitution effects on...

Autores: Krishna,   Vijesh V.; Qaim,   Matin.
The study analyzes ex-ante the adoption of insect resistant Bt eggplant in India. Farmers' willingness to pay (WTP) is estimated using the contingent valuation method. Given the economic importance of insect pests, the average WTP for proprietary Bt hybrids is more than four times the current price of conventional hybrids. Since the private innovating firm has shared its technology with the public sector, it is likely that public open-pollinated Bt varieties will also be released after a small delay. This will reduce farmers' WTP for Bt hybrids by 35%, thus decreasing the scope for corporate pricing policies. Nonetheless, ample profit potential remains. Analysis of factors influencing farmers' adoption decisions demonstrates that public Bt varieties will...

Autores: Lee,   Donna J.; Kim,   C.S.; Schaible,   Glenn D.
Soybean production ranks among the largest agricultural cash crops in the U.S., second only to corn. U.S. soybean production topped 3 billion bushels in 2005 with sales of $17 billion. Approximately 58% of U.S. soybeans are grown in Iowa, Illinois, Minnesota, Indiana, and Nebraska. A small percentage of the U.S. soybean crop, 2%, goes to human consumption in the form of whole beans, soybean oil, and soybean meal products. A third of the crop, 1 billion bushels per year is exported annually to China, EU, Mexico, Japan, and Taiwan, and other countries. Most of the crop, 2 billion bushels, goes to the U.S. livestock industry to feed poultry, hogs, and cattle. Variations in the supply of soybeans thus directly impact livestock production.

A linear programming model of a profit maximizing corn for gain farm is formulated and the quantity of sludge available is parametrically varied to trace out marginal productivity curves under various situations.  The results for Anne Arundel county, Maryland sludge show a range in value from 0-35 $/ton at application rates from 0-20 tons/acre/year for three years.

Autores: Roka,   Fritz M.; Vavrina,   Charles S.
This paper examines the costs and economic benefits of utilizing larger seedling transplant in commercial vegetable production. Larger transplants have been shown to mature earlier and yield more premium graded fruit. Offsetting these benefits is the increased cost of producing larger transplants, primarily from reducing the capacity of a transplant house.

Estimating the Potential Value of Variable Rate Nitrogen Applications: A Comparison of Spatial Econometric and Geostatistical Models
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hurley,   Terrance M.; Oishi,   Kikuo; Malzer,   Gary L.
Site-specific crop response functions (SSCRFs) are useful for estimating the value of variable rate nitrogen applications (VRA), but appropriate statistical models are necessary. Problems estimating SSCRFs using experimental field data include region, spatial, treatment, and strip dependent heteroskedasticity and correlation. We develop a spatial autoregressive error (SARE) model for dealing with these problems and compare results with previous analysis based on a geostatistical (GEO) model. VRA value estimates for the two models differ notably for 1995 data from Southern Minnesota. Furthermore, findings show that the results of a comparison of model performance are location specific.

Estimating the public benefits of mitigating damages caused by invasive plant species in a subsistence economy
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rai,   Rajesh Kumar; Scarborough,   Helen.
This paper presents analysis of a choice experiment (CE) designed to estimate willingness-topay (WTP) to mitigate damages caused by invasive plant species (IPS) in a rural community of Nepal. In order to address the cash constraints problem in a subsistence economy, two payment attributes, labor contribution and membership fee, were included in the choice sets. The results reveal that rural farmers have significant WTP for forest management activities, in terms of both cash and labor contributions. The results also suggest that rural farmers value their time in this context at a different rate to the current wage rate.

ESTIMATING THE RISK OF ALTERNATE TECHNIQUES: NITROGENOUS FERTILIZATION OF RICE IN THE PHILIPPINES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Roumasset,   James A.
The problem investigated is how to estimate expected profits and the risk of using nitrogenous fertilizer for purposes of making fertilizer recommendations and explaining farmer decisions. Three inappropriate methods are discussed and a new method is developed which combines experimentally determined production functions with cross-section data on crop damages. For the Philippine situation analyzed, it appears that using the amount of nitrogen fertilizer which maximizes expected profits does not substantially increase the risk above low nitrogen levels. This finding casts doubt on the hypothesis that farmers' reluctance to use modern techniques is due to their aversion to risk.

Developing groundwater management plans requires a good understanding of the interdependence of groundwater hydrology and producer water use behavior. While state-of-the-art groundwater models require water demand data at highly disaggregated levels, the lack of producer water use data has held up the progress to meet that need. This paper proposes an econometric framework that links county-level crop acreage data to well-level hydrologic data to produce heterogeneous patterns of crop choice and irrigation practices within a county. Together with agronomic data on irrigation water requirements of various crops and irrigation practices, this model permits estimation of the water demand distribution within a county. We apply this model to a panel of 16...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mjelde,   James W.; Dixon,   Bruce L.; Sonka,   Steven T.
Results of comparing updating versus nonupdating modeling assumptions call into question the use of models based on nonupdating strategies as valid representations of actual farmer actions.  If farmers are sequential updaters, the results indicate that models assuming no updating are inaccurate.  The degree of this inaccuracy ranges between 4% and 10% of profits for the study area.  Further, the results indicate that updating appears to be important for both descriptive and prescriptive studies of farmer behavior.

The green industry comprises the production and marketing of woody ornamentals, greenhouse, and turfgrass-related products, and landscape and horticultural services. The industry is market oriented with prospects for future growth. Many state trade organizations have become interested in better measurement of the industry's economic contribution. The contribution of major industry sectors to the Louisiana economy are quantified with a state input-output model. Also presented are study results that are mainly based on readily available data sources. Results suggest that the state industry made a strong contribution to economic activity comparable in size to that of other major agricultural commodities.

Estimation of Actual and Potential Adoption Rates and Determinants of Improved Rice Variety Among Rice Farmers in Nigeria: The Case of NERICAs
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dontsop Nguezet,   Paul Martin; Diagne,   Aliou; Okoruwa,   Victor O.
The article used the ATE estimation framework to derive consistent semi-parametric estimators of population adoption rates and their determinants of the NERICA (New Rice for Africa) rice varieties in Nigeria. Empirical evidence shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random. NERICA awareness was found to be a major constraint to NERICA adoption in Nigeria. Several socioeconomic/demographic characteristics were found to be important determinants of NERICA awareness and adoption. Among those factors are age, gender, major occupation, year of experience and vocational training. In particular, we have found that the NERICA adoption rate in Nigeria would have been up to 76%...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hueth,   Brent; Ligon,   Ethan.
This paper estimates an agency model of contracts used in California's processing-tomato industry. Model estimation proceeds in three stages. We first estimate growers' stochastic production possibilities, and then, for a given vector of preference parameters, compute an optimal compensation schedule. Finally, we compare computed compensations with actual compensations and choose preference parameters to minimize distance between the two. Assuming perfect competition and risk neutrality for processors, we obtain an estimate of .08 for growers' measure of constant absolute risk aversion (where returns are measured in units of $100/ton), and find that growers' effort cost is 1.8% of total operating cost. Welfare        losses from information constraints are...

Estimation of Cost Pass Through to Michigan Consumers in the ADM Price Fixing Case
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cotterill,   Ronald W.
This report analyzes the economic impact of price fixing in the wet corn milling industry on consumers in the State of Michigan. Two of the companies who produce citric acid have pleaded guilty to fixing its price. In this report we assume that price fixing also occurred among HFCS producers. Given the structure of the corn wet milling industry and the direct purchaser industries, the overcharge is essentially uniform across buyers and selling arrangements. We develop an actual economic model of price transmission based upon the three facts: 1) The overcharge as a percent of the processed product value at wholesale and at retail is small, 2) Fixed proportion technology, and 3) consumers have imperfect information about prices so a small price change has no...

Actual farm records were used to evaluate variation of crop yields for corn, wheat, and soybeans grown in Michigan.  The assumption of yields being normally distribute with independent and constant variance was tested for all farms, farms characterized by soil groupings, and individual farms of a selected soil group.  Sufficient evidence was not found to reject the assumption that yield variation is normally distributed with independent and constant variance when all farms were grouped together.  Grouping farms by soil potential showed strong support for yields being independent and normally distributed.  The assumption of constant variance had strong support for wheat, but was weak for corn.  Analysis of individual farms for a selected soil group,...

Autores: Mohanty,   Samarendu; Peterson,   E. Wesley F.
This study estimates demand for wheat differentiated by classes using a dynamic AIDS model for the United States and the European Union (EU). The results suggest that imported wheat is more price responsive than domestic wheat in the U.S. market but not in the EU market. This may suggest that the Canadian policy that reduces prices of Canadian wheat in the U.S. market or U.S. export subsidies that raise prices of U.S, wheat could be expected to give rise to substantial substitution of Canadian for U.S. wheat. It is also found that in the EU, complementary relationships exist between spring and other wheat groups, This complementary relationship between the lower and higher quality wheat in the EU is not surprising because EU millers blend cheaper wheat...

The primary purpose of this paper is to provide updated estimates of domestic own-price, cross-price and income elasticities of demand and estimated price elasticities of supply for various California commodities.  Flexible functional forms including the Box-Cox specification and the nonlinear almost ideal demand system are estimated and bootstrap standard errors obtained.   Partial adjustment models are used to model the supply side.  These models provide good approximations in which to obtain elasticity estimates.  The six commodities selected represent some of the highest valued crops in California.  The commodities are: almonds, walnuts, alfalfa, cotton, rice, and tomatoes (fresh and processed).  All of the estimated own-price demand elasticities are...

This study contributes to the debate regarding the competitiveness of developing countries in the context of globalization. To take advantage of this trend, developing countries will have to position themselves properly through new policies and efficiency in production. In Benin, new orientation of agricultural policy concerns the diversification of exported products. Therefore, and due to the decrease of international price of cotton which represents the main exported crop, cashew nut, the second exported crop by Benin, becomes more interesting for government policy. The study quantified cashew nut production farmers’ efficiency using a stochastic production frontier and a cost function combined with numerical classification. Primary data were collected...

Autores: Winter,   John R.; Whittaker,   James K.
Acreage response functions for wheat are fitted to aggregate data and pooled time-series and cross-sectional data for the Northwest. It was hypothesized that the pooled data approach provides a useful alternative to using aggregate data since it requires fewer timer-series observations for reliable parameter estimation and it does not require the assumption of constant acreage response elasticities throughout the region. The results of this study verify this hypothesis as well as indicate that regional response elasticities for Northwest wheat acreage may differ greatly from national estimates.

Autores: McPhail,   Lihong Lu; Babcock,   Bruce A.
The outlook for U.S. corn markets is inextricably linked to what happens to the U.S. ethanol industry, which depends, in turn, on the level of government subsidies and mandates. We develop a stochastic partial equilibrium model to simulate outcomes for the corn market for the 2008/09 marketing year to gain insight into these linkages. The model includes five stochastic variables that are major contributors to corn price volatility: planted acreage, corn yield, export demand, gasoline prices, and capacity of the ethanol industry. Our results indicate that integration of gasoline and corn markets has increased corn price volatility and that the passage of the expanded ethanol mandates in the Energy Independence and Security Act (EISA) has had modest effects...

This report evaluates the U.S. corn sector, especially changes in ethanol production.  This analysis is based on a series of assumptions about general economic conditions, agricultural polices, weather conditions, and technological change.  Changes in ethanol production will impact the production, feed use, and exports of corn, as well as the general price level.  Federally mandated ethanol usage dictates the growth of ethanol production in the United States.  Other factors have limited impact on corn price.

In parallel with changes in official standards, supermarket chains in Europe have developed prescriptive, production-oriented standards, e.g. the European Union Retailers Produce Working Group for Good Agricultural Practices (GlobalGAP), and are asking their suppliers for produce to be certified according to food-safety and quality standards. There are concerns that the proliferation and enhanced stringency of standards that are imposed by high-income countries can negatively affect the competitiveness of producers in developing countries and impede actors from entering or even remaining in high-value food markets. Yet, in some cases, others argue that such standards can play a positive role, providing the catalyst and incentives for the modernization of...

This paper examines the costs and benefits of producing biomass fuels from mallee eucalypts grown in low rainfall areas of Western Australia. The fuels examined are ethanol and renewable electricity. As a means of examining the competitiveness of these energy sources with conventional fossil fuels, we estimate the price gap between ethanol and petrol and the cost of producing a unit of electricity by conventional means versus biomass electricity. Both comparisons are made on an energy equivalent basis. The potential for future advances in processing technology is built into the analysis. We find that ethanol is not price competitive with petrol, even after considering environmental benefits associated with biomass fuels. This finding raises questions about...

We use recent developments on threshold cointegration approaches to investigate if asymmetric dynamic adjusting processes exist among rapeseed and diesel prices. The results suggest that a threeregime threshold cointegration model suitably explains the dynamics of the data.

European Union Import Demand for In-Shell Peanuts
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Boonsaeng,   Tullaya; Fletcher,   Stanley M.; Carpio,   Carlos E.
This paper analyzes the European Union (EU) import demand for in-shell peanuts from three sources: the United States, China, and the rest of the world. We find that peanuts from different sources are differentiated by EU consumers. The expenditure elasticity is elastic for U.S. in-shell peanuts, which is associated with their higher quality. The conditional own price elasticities are more elastic for U.S. and Chinese in-shell peanuts. These findings have at least two implications. First, U.S. producers and exporters should direct efforts to ensure that in-shell peanuts exported to the EU are of the best possible quality, and, second, promotion efforts should stress the quality of U.S peanuts as an advertising tool.

Evaluating Benefits from Subsistence Pearl Millet Production in the Northern Communal Area of Namibia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Matanyaire,   C.M.
Using experimental data from the northern Namibia pearl millet based subsistence sector the gross margins (GM) and savings on food expenditure (SFE) were computed and compared. The value to cost ratios from the SFE approach were higher than those from the GM approach implying that investment into the selected technologies would be more attractive under subsistence production than under commercial production. This underlines the importance of change agents not to change the farmers' target for farming. Furthermore, it helps explain why subsistence farmers continue to farm when all GM calculations show that they are always loosing money.

The objectives of the paper are twofold: to review valuation methods for plant genetic resources and to develop methods to estimate the past and potential future benefits, both domestic and international, of existing germplasm collections in Papua New Guinea (PNG). The analysis concentrates on PNG’s more important plant subsistence food crops: banana, sweet potato, and taro together with aibika. The paper documents the movement of germplasm in the food crops both within PNG and to international collections. Curators of and breeders using PNG germplasm material are surveyed concerning the future usefulness of this material, and their responses are reported and evaluated. Benefits are valued in terms of the value of future breeding in these species.

Evaluating the Economic Impact of Farmers’ Markets Using an Opportunity Cost Framework
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hughes,   David W.; Brown,   Cheryl; Miller,   Stacy; McConnell,   Tom.
Farmers’ markets presumably benefit local economies through enhanced retention of local dollars. Unlike other studies, the net impact of farmers’ markets on the West Virginia economy is examined. Producer survey results are used in estimating annual direct sales ($1.725 million). Using an IMPLAN-based input-output model, gross impacts are 119 jobs (69 full-time equivalent jobs) and $2.389 million in output including $1.48 million in gross state product (GSP). When the effect of direct revenue losses are included (primarily for grocery stores), the impact is reduced to 82 jobs (43 full-time equivalent jobs), $1.075 million in output, and $0.653 million in GSP.

EVALUATING THE EFFICIENCY OF THE WHEAT TARIFF REGIME IN SOUTH AFRICA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Meyer,   Ferdinand H.
A drastic change in the marketing system of wheat in South Africa has taken place over the past decade.  For the first time an important tariff on wheat was implemented in the form of a variable import levy.  Traditionally, countries have implemented variable import levy schemes in order to protect domestic price guarantees by means of determining a reference price, which was generally above the domestic guaranteed price, below which imports were not allowed into the country.  In this paper the efficiency of the Wheat Tariff Regime in South Africa is examined, after it has been operational for the past seven years.

Intellectual Property Regimes (IPRs) have been justified on the basis that they promote innovation, but it is not always clear that they do so. Empirical studies of IPRs in an Australian context have been limited. Plant variety protection is one form of IPR. The passing of the Australian Plant Breeder’s Rights Act of 1994 has been followed by significant commercialisation of the wheat breeding industry. The purpose of this paper is to consider whether this commercialisation has benefited wheat productivity through varietal improvement. We estimate a linear crop production function, using a random effects Hausman Taylor estimator to evaluate differences in genetic contributions to productivity between public and private wheat varieties commercially released...

Autores: Gunaratna,   Nilupa S.; De Groote,   Hugo; McCabe,   G.P.
Biofortification, or the genetic improvement of the nutritional quality of food crops, is a promising strategy to combat undernutrition, particularly among the rural poor in developing countries. However, traditional methods of impact assessment do not apply to biofortified crops as little or no yield increases are expected. Significant progress has been made to develop maize varieties with improved protein quality, collectively known as quality protein maize (QPM). Evidence for the impact of QPM at the community level, as demonstrated by randomized, controlled studies, was evaluated using meta-analysis. A new and generalizable effect size was proposed to quantify the impact of QPM on a key outcome, child growth. The results indicated that consumption of...

Autores: Colette,   W. Arden; Almas,   Lal K.; Schuster,   Greta L.
Agricultural producers in the Texas High Plains are facing the worst comparative economic conditions since 1913.  Under these circumstances it is desirable to evaluate which programs are beneficial to agricultural producers and which ones are not.  The concept of Integrated Pest Management was introduced to the Texas High Plains in 1976 and since then many IPM practices have been adopted for the four major crops; corn, cotton, sorghum, and wheat.  The reduction in production cost is used as a measure of economic benefit and contingent valuation is used to estimate the value of the environmental benefits.  The IPM practices, which have been adopted, reduce the production cost by more than $173 million per year.  In addition the practices reduce...

Autores: Roberts,   Roland K.; English,   Burton C.; Mahajanashetti,   S.B.
Potential benefits of variable rate nitrogen application are illustrated and information needs identified. Lower costs of precision farming services, higher crop prices, and greater divergence in yield response potentials across management zones reduce the spatial variability required for profitable variable rate application. Information needs include identification and measurement of management zones within a field and estimation of management zone yield response functions, crop and input prices, and the cost of precision farming services.

This study examines the effects of climatic conditions on interactions among pea and lentil yields, pea aphid Acyrthosiphon pisum (Harris) infestations, and outbreaks of PEMV (Pea enation mosaic) and BLRV (Bean leaf roll) viruses in the Palouse region of easternWashington. The study analytically and empirically evaluates the effects of aphid outbreaks on per acre yields, implicitly including the effects of adopted pest management activities and explicitly taking into account possible effects of climatic conditions on the severity of pea aphid outbreaks. The results show that aphid outbreaks have historically decreased pea and lentil yields by approximately 5% and 7% on average respectively.

Dockage levels in U.S. wheat exports have been a continuing concern.  Recent proposals have focused on changes in U.S. grain standards that would include dockage limits.  In this report, dockage trends and practices were documented and effects of prospective changes evaluated.  Results indicate the marketing system is currently working effectively with costs of extra cleaning being borne partly by buyers, elevators, and to some extent farmers.  Suggested mandates would increase cleaning and result in increased costs (ultimately discounts to growers) and potentially in shifts in grades purchased.  Proposed changes in grain standards are also a departure from the generally followed approach to regulation in the United States.  In this case, a regulation is...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cullen,   Ross; Forbes,   Sharon; Grout,   Rachel; Smallman,   Clive.
Conservation biological control (CBC) aims to improve conditions for natural enemies in agricultural landscapes and has the goal of reducing pest species below threshold level to thus avoid the need for synthetic chemicals.  The CBC approach has been introduced in several counties, including New Zealand.  Agricultural R&amp;D is widely studied, however agricultural innovations and their adoption is less studied.  A CBC practice introduced in Waipara vineyards is described in this paper and an evaluation of the uptake and economic sustainability of this innovation is provided.  Results indicate that there are ongoing costs involved with maintaining the innovation and that adoption of the innovation is highly variable across winegrowing properties.

The identification of economically sensitive traits is a critical step in the breeding process as it defines the direction of the breeding program. Quantifying how each trait affects the profitability of the production system further increases the efficiency of a breeding program. Production activities are ultimately aimed at maximising the level of consumer satisfaction with the product concerned which is, in turn, relfected by the profitability of the growing and processing stages of the production process. In that regard, breeding objectives need to be consistent with maximising the profitability of the farm production sector by producing genotypes with improved performance. By assigning economic weights to different traits, genotypes with differing...

EVALUATION OF FEASIBILITY OF FRUIT AND VEGETABLE CROPS USING MARKET WINDOW ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Adrian,   John L., Jr.; Upshaw,   Cran; Mook,   Richard.
Fruits and vegetables have been identified as potential production alternatives to use available farm resources. Several "market window" studies have been undertaken to evaluate such feasibility. These state and regional studies are analyzed and compared to identify underlying assumptions and methodologies. Recommendations of the studies are evaluated on an aggregate basis and limitations of the market window technique are identified and discussed. The technique was judged to be useful in planning because it involves consideration of potential costs to be incurred, markets to be evaluated, and price expectations for the various commodities considered.

Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were...

Simulation of production budgets were used to compare net discounted returns and the distribution of returns under alternative risk-mitigation scenarios.  Results indicate that the combination of freeze protection and crop insurance increases expected net discounted 20-year returns while decreasing the downside risk.  Break-even prices ranged from $.257 to $.289 per pound.  Crop insurance returns were constant across price.

EVALUATION OF SELECTED FRESH VEGETABLE TERMINAL MARKETS: A STOCHASTIC DOMINANCE APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hinson,   Roger A.; Lee,   John G.; Huh,   Mooyul.
Vegetable production can offer a high-valued cash crop alternative. While returns may be high, vegetables are perceived to have more risk than conventional row crops. This study used stochastic dominance analysis to evaluate terminal market price risk for four vegetable crops across five market locations. Results from the analysis identify differences in efficient market selection depending on the form which price risk follows. While vegetables as a whole are considered risky, substantial differences in the type of terminal market price variability existed between the commodities.

Considering pest management in terms of a set of technology characteristics allows an investigation of various pest-management characteristics and how they relate to a total pest-management package.  Employing restricted and unrestricted least squares in this investigation indicates the unique impact individual pest-management characteristics exert on net returns.  A Stein-rule estimator is also employed in assessing this impact.

Evaluation on HYV of Pulse crops in Myanmar
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Thaung,   Nyein Nyein; Choi,   Kyu Seob.
This paper shows the evaluation on HYV of pulse crops in Myanmmar. This system is evaluated based on growth decomposition model. The result of the area response function showed that the price of pulses was significant factor affecting farmers' land allocation decisions. The price of pulses and fertilizer, however, not affected output by influencing the utilization of inputs and hence, crop yield. The results of the area and yield response functions are consistent with the hypothesis of the study. The contribution of technology variables on changes in area, yield, and production will estimate by applying a decomposition model. The result showed that the adoption of HYVs and the increase in nitrogen use were the predominant sources of growth in pulses...

EVIDENCE FOR A WEATHER PERSISTENCE EFFECT ON THE CORN, WHEAT AND SOYBEAN GROWING SEASON PRICE DYNAMICS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Stevens,   Stanley C.
The growing season weather in the corn, wheat and soybean production areas of the United States is an important determinant of the U.S. supply of these commodities.  The weather and climatology literature strongly suggest that during the summer months there is a degree of persistence in the North American weather patterns.  Given this nonrandom character of weather and given that the corn, wheat and soybean belts are geographically concentrated enough to be dominated by a regional weather phenomenon, their futures markets are hypothesized to reflect this assimilation of nonrandom weather information as nonrandom price fluctuations.  An empirical test of this question is the subject of this paper.

Evidence of Scope Economies in Australian Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Villano,   Renato A.; Fleming,   Pauline; Fleming,   Euan M.
Scope economies can be used in studies of farming systems to provide a measure of synergies between different farm enterprises and between activities within farm enterprises. In this paper, they are reported for farms in three benchmarking groups in Australia by estimating stochastic input distance functions and calculating an 'economies of scope parameter'. Evidence of significant scope economies between sheep and crop enterprises, and between beef and crop enterprises, is presented and discussed. Similar evidence is reported between wool and lamb activities and wool and mature sheep trading activities within the sheep enterprise.

Evidence on trends in the single factoral terms of trade in African agricultural commodity production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fleming,   Euan M.; Fleming,   Pauline.
The ability of African countries to achieve sustained improvements in agricultural incomes depends on their ability to generate total factor productivity (TFP) change in their agricultural sectors and adjust to movements in agricultural output and input prices. The single factoral terms of trade index measures these changes, calculated as changes in the product of TFP and the agricultural terms of trade. Estimates of the single factoral terms of trade index for the selected commodities over the period 1970-2002 are reported and discussed for 33 African countries for which data sets are available. The index is estimated for producers of coffee, cocoa, copra, palm kernel oil, coconut oil, palm oil, rice, cotton and sugar using annual agricultural sector...

The net impact of pest-resistant GM crops on the welfare of both producers and consumers in developing countries is currently unknown and subject to speculation. This study uses choice-based conjoint protocol to estimate the net impact of pest-resistant Genetically Modified (GM) cowpea on net social welfare in Benin given price and income risks. Results imply that Bt cowpea will increase expected net social welfare by about $US 50 million per year in Benin given no inefficiencies in the seed sector. If inefficiencies in the seed sector are such that cowpea growers can access Bt cowpea seeds only 50% of the time, net benefits from Bt cowpea drop to about $US 11 million per year.

Examining AWB’s market power in the international wheat market
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chang,   Hui-Shung (Christie); Martel,   William; Berry,   Robert.
The Australian wheat marketing system has been through a number of stages of deregulation in recent years. However, the AWB still maintains the monopoly selling rights of Australian wheat exports. The AWB and its supporters justify the single desk by arguing that the monopoly power enables them to gain a higher price in the export markets. Opposition to the single desk argues that Australia does not produce enough wheat to influence prices. The objective of this study is to test the market power hypothesis by examining the quantity - price relationship of Australian wheat exports and the stability of this relationship over time using annual data from 1961 to 2000.

It has been a long time since we have seen a cost of production study for horticultural crops, notably processing vegetable crops, in New York State; however, research in this arena is completed in many other states and continues to offer useful information to industry stakeholders. This type of information is especially important in the processing vegetable sector in New York State as it has seen substantial acreage decreases in recent years. Here we develop a survey to collect data from processing vegetable growers in New York State and use it to calculate costs and net returns of producing snap beans and green peas. Our results indicate that the average cost of producing snap beans in New York State is $568 per acre and is $563 per acre for green peas;...

Autores: Kostandini,   Genti; Mills,   Bradford F.; Omamo,   Steven Were; Wood,   Stanley.
This paper examines the ex-ante benefits of transgenic research on drought in eight developing countries, including the potential magnitude of private sector profits. The framework employs country-specific agroecological-drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research. Risk benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits, representing 41 percent of total benefits across the eight countries. Further, estimated annual benefits of $US 93 million to the private sector suggest that significant incentives exist for private sector participation in varietal drought tolerance research.

The study introduces an ex-ante evaluation concept into the analysis of weather-based index insurance effectiveness. We conduct our ex ante analysis by distinguishing between two consecutive periods: the first period is used for determining insurance parameters and optimal number of insurance contracts for an arable farmer; and the subsequent one is considered for the evaluation of the risk reduction due to the insurance contract defined in the first period. The study also employs the common ex-post approach by specifying and evaluating insurance contracts by means of the same period. We compare the empirical results obtained from these alternative evaluation approaches and thus investigate the ability to forecast empirically insurance schemes risk...

Autores: Tiller,   Kelly; Feleke,   Shiferaw T.; Starnes,   Jane H.
This study explores the relationship between family/farm characteristics and the probability of exiting burley tobacco farming in Tennessee, North Carolina, and Virginia. Following the termination of the federal tobacco program in 2004, 54% of burley tobacco–growing households in Tennessee, North Carolina, and Virginia exited burley tobacco farming by 2006. Tobacco yield, tobacco farm cash receipts, tobacco price, off-farm employment, and farm size are the most dominant variables discriminating between exiting and surviving tobacco farms. Data for this study came from a mail survey of burley tobacco producers in Tennessee, Virginia, and North Carolina in May 2006.

Autores: Sherlund,   Shane M.; Barrett,   Christopher B.
This paper uses a unique panel data set and data envelopment analysis (DEA) to obtain estimates of technical efficiency for 492 traditional rice plots in Côte d'Ivoire.  The objective of this paper is to explore the importance of explicitly controlling for exogenous shocks to production in technical efficiency estimation.  We show how omission of such variables in highly stochastic production environments can lead to serious inferential errors, with potentially significant policy implications.  Conventional DEA estimation of a production frontier, followed by second-stage Tobit estimation of the correlates of plot- level technical efficiency, suggest widespread and substantial inefficiency related to crop fragmentation and seed varieties.  However, when...

O sistema agroflorestal (SAF) é uma técnica de produção agrícola que combina espécies arbóreas lenhosas (frutíferas e/ou madeireiras) com cultivos temporários, de ciclo anual. Os SAFs têm a capacidade de, ao longo do tempo, tornar produtivas áreas degradadas. Tem-se então uma importante ferramenta, apropriada para agricultores familiares, como base para programas públicos de combate à pobreza rural, segurança alimentar, conservação de recursos naturais e educação ambiental. Na região do Alto Vale do Jequitinhonha a prática do SAF foi proposta pelo Centro de Agricultura Alternativa Vicente Nica, CAV, buscando a recuperação das áreas intensamente exploradas e degradadas, conhecidas no local como peladores, a fim de reconvertê-las em áreas produtivas.

Autores: Shogren,   Jason F.; Parkhurst,   Gregory M.; Hudson,   Darren.
We illustrate the experimental method by examining bidding behavior for controversial goods, i.e., goods in which bidders have positive and negative values. Our results suggest that bidding behavior differs across auction type. Bidders with positive induced values bid sincerely in a WTP auction. Bidders bid conservatively, however, in the WTA auction, foregoing profitable opportunities. Informing bidders of their optimal strategy serves to attenuate bidding discrepancies but does not eliminate them. Treating the WTP and WTA auctions as equivalent given positive and negative values could lead one to overstate the costs relative to the benefits of the controversial good.

Autores: Dhungana,   Basanta R.; Nuthall,   Peter L.; Nartea,   Gilbert V.
Efficiency has been proven to be an important managerial tool in improving total factor productivity in agriculture. The four sources of economic inefficiency: allocative, technical, pure technical and scale inefficiency of a sample of seventy-six Nepalese rice farmers were examined using the data envelopment analysis (DEA) decomposition method. The inefficiency indices computed by the DEA were then used as the dependent variable in a Tobit (censored) regression model using decision- makers’ attributes as the explanatory variables. The results revealed relatively large inefficiencies among the farms sampled. The average economic, allocative, technical, pure technical and scale inefficiencies were 34%, 13%, 24%, 18%, and 7% respectively. There is also a...

Although technology adoption has been the subject of a great deal of economic research, that focused on the economics of adoption of low-input "sustainable" systems has been much more limited and recent. This paper attempts to explain the recent decline in the use of cover crops using in maize farming in the Department of Atlantida, Honduras. In the early 1970's, farmers in the region began rotating maize with the velvetbean (mucuna ssp.), a system learned from Guatemalan immigrants. Tohe mucuna-maize system decreased the labor required for maize farming even as it increased yields, prevented erosion, and conferred a variety of other agronomic benefits. By 1992, estimates show that the system had diffused among more than 60% of farmers in the Department....

This article analyses the current climate-dependent spatial distribution of corn and corn-cob-mix in Baden-Württemberg using 2007 data at the county and community level. We use OLS and spatial econometric models to estimate the effects of different climate and non-climate variables on the share of grain maize in UAA. Whereas the temperature effect is missed by means of OLS regression, the adequate spatial error model at the county level yields a highly significant positive effect of mean annual temperature. Additionally, it displays a temperature cut-off point after which corn share is less likely to rise due to temperature increase. These effects are supported by a non-spatial multinomial logit model at the community level. The latter further indicates...

EXPORT SUBSIDIES AND SWITCHING COSTS IN AN IMPERFECTLY COMPETITIVE INTERNATIONAL WHEAT MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kallio,   Panu K.S.; Abbott,   Philip C.
Switching costs affect importer decisions, hence impacts of subsidies over time. Dynamic, game theoretic simulations of EU-US competition for Moroccan wheat imports suggest firms charge lower prices and governments award higher subsidies with switching costs.  Policy under alternative institutional arrangements depends on the extent of switching costs, measured here econometrically.

Export Vegetable Production in Kenya under the EurepGAP Standard: Is Large “More Beautiful” than Small?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mausch,   Kai; Mithofer,   Dagmar; Asfaw,   Solomon; Waibel,   Hermann.
This paper defines three types of typical certified farms in Kenyan export production: smallholder farms, large-scale contracted farms, and exporter-owned farms. It assesses their economic performance, compares the financial cost of compliance with the EurepGAP standard, and analyses transaction costs. Results show that larger farms are not generally performing more efficiently compared to smallholders who implemented the EurepGAP standard. Despite higher monitoring costs as a result of the introduction of standards, smallholder vegetable producers remain an important source for the exporter companies.

Exporting Kenya's Horticultural Products: Challenges and Opportunities in The 21st Century
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nyangweso,   P.M.; Odhiambo,   Mark O.
The horticultural export sector has experienced rapid growth since 1966 because of the active role by the private sector and minimum government intervention. The European Union is the largest consumer of Kenyan horticultural exports. Kenyan horticultural exports to the European Union accounted for 45 percent of the total exports in 2000. In recent years, horticultural export growth has declined. The quality of production has declined, following a reduction of the role of exporters in supporting production by small-scale farmers. This has reduced Kenya’s competitiveness in the horticultural export market at time when the sector is faced with increased competition from other producer countries. The reform of the European Union Common Agricultural Policy...

This chapter discusses the implementation challenges of the WHO Guidelines on safe wastewater use pertaining to the adoption of the so-called ‘post-treatment’ or ‘non-treatment’ options, like safer irrigation practices or appropriate vegetablewashing in kitchens. Due to limited risk awareness and immediate benefits of wastewater irrigation, it is unlikely that a broad adoption of recommended practices will automatically follow revised policies or any educational campaign and training. Most of the recommended practices do not only require behaviourchange but might also increase operational costs. In such a situation, significant efforts are required to explore how conventional and/or social marketing can support the desired behaviour-change towards the...

Factor Input Demand Subject to Economic and Environmental Risk: The Case of Nitrogen Fertilizer in Corn Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carriker,   Gordon L.
Nitrogen (N) fertilizer demand in relation to economic and environmental risks associated with N-fertilizer management are examined. Both nominal and environmental damage-adjusted net returns distributions are evaluated using stochastic dominance analysis. Results suggest that, in the absence of environmental risk, N demand becomes more elastic as farmers become more risk averse. When environmental risk is introduced to the decision-making process, N demand becomes even more elastic.

FACTORS AFFECTING ADOPTION OF IMPROVED MAIZE SEEDS AND USE OF INORGANIC FERTILIZER FOR MAIZE PRODUCTION IN THE INTERMEDIATE AND LOWLAND ZONES OF TANZANIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kaliba,   Aloyce R.; Verkuijl,   Hugo; Mwangi,   Wilfred.
This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm trials for varietal evaluation and demonstration purposes.

FACTORS AFFECTING DEMAND AND SUPPLY OF RICE IN SIERRA LEONE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kargbo,   Alimami M.
Sierra Leone, like most developing  countries is primarily agricultural, with about 75 percent of its population getting its living from farming.  The main characteristic of its farming is the large number of small holdings-averaging about two hectares per farm.  Most of these farms are fragmented.  Large-scale farming is a fairly recent development and the few large farms are either government or quasi-government institutions, confined to crops that require expensive machinery and timely processing.  In the country's search for new sources of economic expansion, agriculture assumed first priority.  This was due, in part, to the fact that a large percentage of the population derived its living from agriculture.  In addition, the development of agriculture...

Factors Affecting Direct and Indirect Energy Use in U.S. Corn Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Musser,   Wesley N.; Lambert,   Dayton M.; Daberkow,   Stan G.
The recent volatility of energy prices has numerous policy implications for agriculture. A better understanding of the factors associated with energy consumption as related to crop production management decisions and technology use may provide insight about how producers might respond to program or market incentives targeting energy use in particular, and soil and water conservation in general. Adoption of minimum tillage could reduce erosion and improved fertilizer management practices could reduce nitrogen runoff. Energy costs may be reduced with adoption of reduced tillage technology, improved drying and irrigation systems, or more careful attention to the application and timing of fertilizers.

Factors Affecting Farmers’ Utilization of Agricultural Risk Management Tools: The Case of Crop Insurance, Forward Contracting, and Spreading Sales
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Velandia,   Margarita M.; Rejesus,   Roderick M.; Knight,   Thomas O.; Sherrick,   Bruce J.
Factors affecting the adoption of crop insurance, forward contracting, and spreading sales are analyzed using multivariate and multinomial probit approaches that account for simultaneous adoption and/or correlation among the three risk management adoption decisions. Our empirical results suggest that the decision to adopt crop insurance, forward contracting, and/or spreading sales are correlated. Richer insights can be drawn from our multivariate and multinomial probit analysis than from separate, single-equation probit estimation that assumes independence of adoption decisions. Some factors significantly affecting the adoption of the risk management tools analyzed are proportion of owned acres, off-farm income, education, age, and level of business risks.

Factors affecting farmers’ willingness to adopt salt-tolerant forage crops in south-eastern Tunisia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chebil,   Ali; Nasr,   Hafedh; Zaibet,   Lokman.
This paper analyzed the factors that affect farmers’ willingness to adopt salt-tolerant forage for livestock, using a Tobit model. The data used for the empirical analysis was obtained from a survey of 97 farmers in southeastern Tunisia. The results of this study show that variables related to age, education level, the salinity level of water and membership in a farmers’ association do not significantly influence the degree to which salt-tolerant forage production is adopted. It did, however, find a positive relationship between off-farm income availability and adoption. In addition, the flock size variable, expressed in Standard Livestock Units, has a significant and positive relationship with adoption. This indicates farmers’ need to cover their forage...

FACTORS AFFECTING FRESH POTATO PRICE IN SELECTED TERMINAL MARKETS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Goodwin,   Harold L., Jr.; Fuller,   Stephen W.; Capps,   Oral, Jr.; Asgill,   Oladimagi W.
Monthly, quarterly, and annual cross-sectional and time-series data for the period 1982-85 were analyzed to identify factors affecting terminal market price for four types of fresh potatoes. Results indicated that state of origin, terminal market package type, and season of marketing were significant quality variables affecting price. Price differences among potato types because of season of marketing and stocks of fall potatoes were evident. These results suggest that cultivar selection, cultural practices, planting and harvesting schedules, packaging, and market selection – factors which are ultimately controlled by growers and grower/shippers – can be utilized effectively as mechanisms to increase price and expand markets.

Factors Affecting Hay Supply and Demand in Tennessee
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bazen,   Ernest F.; Roberts,   Roland K.; Travis,   John; Larson,   James A.
Understanding the interactions between supply and demand for hay is important because of hay’s significance to the agricultural sector and economy, and because hay is an important crop on highly erodible soils. As an example, Tennessee has the most erodible cultivated cropland in the United States (Denton, 2000), nearly half of the state’s current CRP acreage contracts are set to expire in 2007 (U.S. Department of Agriculture, 2006), and hay is one of the most economically important crops produced in the state (U.S. Department of Agriculture, 2004). Cross (1999) attributed the upward trend in Tennessee hay acreage since 1980 to an increasing number of farmers who were searching for alternative production activities, such as hay, pasture and livestock, to...

Factors Affecting Hedging Decisions Using Evidence from the Cotton Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Isengildina,   Olga; Hudson,   Darren.
Few farmers utilize futures and options markets to price their crops despite significant educational efforts. This study seeks to analyze producer hedging behavior within the framework of the overall marketing behavior. Producer marketing behavior is modeled as a simultaneous choice between cash sales, cooperative marketing and forward contracts, and hedging. A multinomial logit model is used for empirical estimation using data from a survey administered to a sample of cotton producers from across the U.S. The most important factors that explain the use of forward pricing by cotton producers are producer preferences, farm size, use of crop insurance, risk aversion, income from government payments and off-farm income. Risk aversion, off-farm income, crop...

Factors affecting soil conservation decisions of KwaZulu-Natal commercial sugarcane farmers
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ferrer,   Stuart R.D.; Nieuwoudt,   W. Lieb.
Technological information is used to assess KwaZulu-Natal commercial sugarcane farmers' intra-plot (panel) soil conservation relative to requirements of the Conservation of Natural Resources Act of 1983. Findings indicate that farmers consider enforcement of the Act to be unlikely and that 28 percent of farmers surveyed do not meet adequate intra-panel soil conservation standards. Multiple regression is used to estimate models representing intra-panel soil conservation adoption and soil conservation effort. Results show that farmers have greater conservation adoption and effort on their relatively steeper panels and implement soil conservation plans on these panels first. Amongst other factors, education and use of extension information sources are...

FACTORS AFFECTING THE IMPORT OF WHEAT IN SAUDI ARABIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Al-Goosi,   Adbullah I.
The modern economy of Saudi Arabia depends primarily on oil exports.  Oil being the source of most of the country's exports, foreign exchange, and government revenues, it follows that the oil sector affects the economy rather than the economy affecting the oil sector.  Saudi Arabia lacks natural resources for most of its essential goods and because of sudden high income, it has become necessary to introduce new strategies for producing necessary goods and services.  Since Saudi Arabia depends more on foreign trade then most other countries in the world, it has to export almost all of the oil it produces - oil bing the country's only export commodity.  Thus, Saudi Arabia is almost entirely dependent on the international market, which is, in turn, affected...

The likelihood of adopting corn rootworm (CRW) Bt seed technology was analyzed using an ordered logit model. Data used to estimate the model came from USDA’s 2001 Agricultural Resource Management Survey. Statistically significant variables include operator age, farm type, farm size, rootworm loss and current treatment for rootworm, off farm labor, and Bt technology for corn borer. The likelihood of adoption was not related to crop rotation, tillage system, new variant CRW region, or education.

Factors affecting the use of forward pricing methods in price risk management with special reference to the influence of risk aversion
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jordaan,   Henry; Grove,   Bennie.
Risk aversion is the primary reason for farmers to use forward pricing methods to hedge against price risk. Previous international research on farmers’ forward pricing behaviour found inconsistent results with respect to the relationship between risk aversion and the use of forward pricing methods. Ordinary Least Squares (OLS) regression is used in this research to investigate the relationship between the proportion of maize Vaalharts maize producers are willing to forward price and risk aversion. The quantity decision is modelled conditional on the adoption decision to ensure that the modelling procedure does not force the same variables to influence the two decisions in the same way. Regression results showed that more risk averse farmers are forward...

This study used Rosen's methodology of deriving a marginal implicit price series from traditional hedonic modeling and then using this series to estimate a demand model.  This procedure was applied to Kansas Hard Red Winter wheat protein.  Results were mixed.  Own-district protein level was not economically significant; however, an increase in other Kansas district's protein level and the North Dakota Hard Red Spring protein level may have a slight economic impact on own-district protein premium.  The results of this study indicate that new varieties of wheat developed that increase protein content without loss of yield and that are regional specific can impact the price or wheat in other areas.

Factors Contributing to Zambia's 2010 Maize Bumper Harvest
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)

Zambia’s maize crop grew by roughly 48% between the 2009 and 2010 harvests, leading to the largest crop recorded in recent history. The 2009 maize harvest was also very good, making the 48% rise in 2010 even more remarkable. The forces driving that increase, however, remain widely debated. Many in government and media have attributed the recent production increase to the government’s fertilizer subsidy program as well as to the state’s recent efforts to raise maize prices through the operations of the Food Reserve Agency. Others have argued that the bumper harvest is partially due to the adoption of conservation farming techniques by farmers. Still others attribute the maize production growth mainly to favorable weather. Unfortunately, none of these claims...

Key Points • Zambia’s maize crop grew by 48% between the 2009 and 2010 harvests, leading to the largest crop recorded in recent history. • Yield growth accounted for 59% of the maize production growth between 2009 and 2010. Expansion of area planted to maize explains an additional 23%, while the remaining 18% can be attributed to a rise in the ratio of harvested to planted land. • Favourable weather conditions contributed 47% of the maize yield growth between 2009 and 2010, whilst, 25% came from increased fertilizer use from both the private and public sectors, and 23% from area expansion. The remaining 5% can be attributed to hybrid seed use and improved management. • Due to favorable weather conditions in both 2008/09 and 2009/10 growing seasons, maize...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ariga,   Joshua; Jayne,   Thomas S.; Nyoro,   James K.
The objective of this study is to identify the factors responsible for the impressive growth in fertilizer use in Kenya since market liberalization in the early 1990s. Over the past 10 years, fertilizer consumption has risen by 35%. So far, it is unknown whether smallholder farmers are responsible for this growth or whether it is being driven mainly by the large-scale and/or estate sectors. Moreover, it is important for policy makers to know whether the increased fertilizer consumption is being devoted to smallholder food crops or whether industrial crops such as tea and sugarcane are responsible for this growth. This study addresses these questions using nationwide survey data on smallholder fertilizer use patterns between 1996 and 2004. The study also...

Factors Influencing ACRE Program Enrollment
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Woolverton,   Andrea E.; Edwin,   Young.
Authorized by the 2008 Farm Act, the Average Crop Revenue Election (ACRE) program is the first revenue-based, income-support program that calculates payments using recent market prices and a producer’s actual plantings. The payments are triggered when a farm’s revenue and State revenue (price multiplied by yield per planted acre) fall below a calculated guarantee for a crop. By contrast, other income-support programs are based on legislated rates and support levels, computed using a farm’s base acres and payment yields. Had the ACRE program been available during crop years 1996-2008, this report shows that farmers would have benefited more from participating in 2002 Farm Act programs than in the hypothetical ACRE program. The report further suggests that,...

This study applied logit and logit transformed regression to examine factors affecting the adoption of orange flesh sweet-potatoes (OFSP), and intensity of such adoption, by a representative sample of 340 farmers in the Busia and Rachuonyo districts of Kenya in 2009. The study also investigated whether participation in a value chain extension intervention programme increased these farmers’ likelihood of adopting OFSP. The results suggest that the district where the farmer comes from, knowledge on value addition and nutritional benefits, and availability of vines were the key factors for adoption. The results also suggest that participation in a value chain extension programme enhanced the probability of adoption. Factors affecting intensity of adoption...

Factors influencing adoption of agroforestry among smallholder farmers in Zambia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kabwe,   Gillian; Bigsby,   Hugh R.; Cullen,   Ross.
Agroforestry technologies have been extensively researched and introduced to smallholder farmers in Zambia for over two decades. Despite the research and extension effort over this period, not many farmers have adopted these technologies. The purpose of this paper is to determine why agroforestry technologies are not being taken up by examining factors that influence the adoption of agroforestry practices. Based on data obtained from 388 farming households, statistical analysis show an association between adoption of both improved fallows and biomass transfer technologies with knowledge of the technology, availability of seed, and having the appropriate skills. In addition some household characteristics are found to be linked to the incidence of adoption....

Personal digital assistants (PDA) and handheld global positioning systems (GPS) have become increasingly important in cotton production but little is known about their use. This research analyzed the adoption of PDA/handheld GPS devices in cotton production. A younger farmer who used a computer in farm management and had a positive perception of Extension had a greater likelihood of adopting the devices. In addition, farmers who used complementary remote sensing, plant mapping, and grid soil sampling information were more likely to use PDA/handheld GPS devices. Finally, the COTMAN in-field decision support program from Extension also positively impacted adoption.

FACTORS INFLUENCING PRODUCER SUPPORT FOR A STATE MANDATORY SEED LAW: AN EMPIRICAL ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Makus,   Larry D.; Guenthner,   Joseph F.; Lin,   Biing-Hwan.
A probit model identifies characteristics influencing Idaho potato producer support or opposition to a state mandatory certified seed law. Economic self interest appears to be the most important influencer. Current users of certified seed and growers of certified seed are strong supporters. However, producer attitudes about the impact of seed-borne diseases and effectiveness of certified seed as a control mechanism also are important. Respondent characteristics (gross farm income, potato acreage, and geographic region of the state) seem to be less important influencers.

Factors Influencing the Profitability of Fertilizer Use on Maize in Zambia.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Xu,   Zhiying; Guan,   Zhengfei; Jayne,   Thomas S.; Black,   J. Roy.
Fertilizer use remains very low in most of Africa despite widespread agreement that much higher use rates are required for sustained agricultural productivity growth. This study estimates maize yield response functions in agro-ecological Zone IIA, a relatively high potential zone of Zambia, to determine the profitability of fertilizer use under a range of small farm conditions found within this zone. The theoretical framework used in this study incorporates agronomic principles of the crop growth process. The model distinguishes different roles of inputs and non-input factors in crop production. We estimate the effects of conventional production inputs as well as household characteristics and government programs on maize yield for households in the...

Factors Influencing the Profitability of Fertilizer Use on Maize in Zambia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Xu,   Z.; Guan,   Zhengfei; Jayne,   Thomas S.; Black,   J. Roy.
Major Findings: The additional maize produced from a given amount of fertilizer applied varied widely across households even after largely controlling for soil and rainfall conditions. The median estimated response rate was 15.9kgs of maize per kg nitrogen applied; Under the range of conditions and smallholder management practices, average maize fertilizer response rates declined as the application rate increased beyond 2 bags of urea and 2 bags of D compound; Factors raising the response rate and profitability of fertilizer use included timely availability, application rates less than the MOA 4x4 recommendation, use of animal draft power in land preparation, and use of hybrid seed. In remote areas, and given current management practices, fertilizer use...

Factors Influencing Wheat Yield and Variability: Evidence from Manitoba, Canada
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carew,   Richard; Smith,   Elwin G.; Grant,   Cynthia.
Production functions to explain regional wheat yields have not been studied extensively in the Canadian prairies. The objective of this study is to employ a Just-Pope production function to examine the relationship between fertilizer inputs, soil quality, biodiversity indicators, cultivars qualifying for Plant Breeders’ Rights (PBR), and climatic conditions on the mean and variance of spring wheat yields. Using regional-level wheat data from Manitoba, Canada, model results show nitrogen fertilizer, temporal diversity, and PBR wheat cultivars are associated with increased yield variance. Mean wheat yield is reduced by the proportion of land in wheat, the interaction of growing temperature and precipitation, and spatial diversity. By contrast, higher soil...

Autores: Bertuglia,   Adriana; Calatrava-Requena,   Javier.
The adoption by farmers of Good Agrarian Practices (GAP), that favouring the environment and assure food quality and safety, is being a frequent fact. Considering the plastic covered horticulture, these kind of practices can be of different nature: use of organic fertiliser, made of crops rotations, use of recyclable plastic as greenhouse cover, good management of organic residuals (use of containers), recycling of plastic containers, etc. This paper, wich try to analyse the adoption of GAP by protected vegetable growers, is based on a survey carried out to 114 farmers in the southeast coastline of Spain, asking for the level of adoption of a set of GAP. From the information gathered on the suvey, an aggregated index of adoption has been performed, and the...

According to a Virginia-North Carolina watershed survey, farmers view advisory services as having the effect of decreasing pesticide use.  However, analysis of pesticide use shows that hired staff, scouting personnel, and extension agents are associated with higher pesticide toxicity applied to cotton while chemical dealers and scouting personnel are associated with higher toxicity applied to peanuts.

Farm Animal Welfare, Consumer Willingness to Pay, and Trust: Results of a Cross-National Survey
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nocella,   Giuseppe; Hubbard,   Lionel J.; Scarpa,   Riccardo.
Higher animal welfare standards increase costs along the supply chain of certified animal-friendly products (AFP). Since the market outcome of certified AFP depends on consumer confidence toward supply chain operators complying with these standards, the role of trust in consumer willingness-to-pay (WTP) for AFP is paramount. Results from a contingent valuation survey administered in five European Union countries show that WTP estimates were sensitive to robust measures of consumer trust for certified AFP. Deriving the WTP effect of a single food category on total food expenditure is difficult for survey respondents; hence, a budget approach was employed to facilitate this process.

Farm Level Analysis of Risk, and Risk Management Strategies and Policies: Evidence from German Crop Farms
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Anton,   Jesus; Kimura,   Shingo.
This paper describes farmer’s exposures to risks at the individual farm level and develops a model representing the decisions of an individual risk averse farmer facing variability in both prices and yields. A set of stylised risk market instruments is represented.  The model is calibrated using farm level data from Germany.  Monte-Carlo simulations of the random variables are run, and the corresponding optimal responses are obtained. The main focus of this paper is the interactions between government payments and the farmers’ use of risk market instruments in terms of the potential crowding out of such instruments and impacts on farm return and welfare. Unlike other studies this paper models farming response to payments in terms of production and the use...

FARM LEVEL DEMAND FOR PECANS RECONSIDERED
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wells,   Gary J.; Miller,   Stephen E.; Thompson,   C. Stassen.
Previous studies have consistently indicated the anomalous result of a price inflexible demand for pecans.  However, these efforts did not have an adequate measure of pecan stocks available and, as a result, stocks were either excluded from consideration or a proxy variable was introduced.  A time series of pecan stocks is now available.  Use of this time series in a price dependent demand function results in a flexible farm level demand for pecans.  This points out the danger of excluding an appropriate variable or using a so-called "reasonable" proxy variable.

Farm Level Impacts of Bt Corn Adoption in a Developing Country: Evidence from the Philippines
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mutuc,   Maria Erlinda M.; Pan,   Suwen; Rejesus,   Roderick M.; Yorobe,   Jose M., Jr.
This article examines the ex post farm-level impacts of Bt corn adoption in the Philippines. Using an econometric approach that addresses simultaneity, selection, and censoring problems, we show that Bt corn adoption provides modest but statistically significant increases in farm-level yields and profits. Furthermore, our results suggest that farm-level yield and profit impacts of Bt corn adoption are underestimated when censoring in the pesticide application variable is not considered in the estimation procedures. Previous literature have emphasized the importance of simultaneity and selection problems but this is the first study that have raised the issue of censoring problems in estimating the farm-level effects of Bt corn adoption.

Autores: Umeh,   Joseph Chinedu; Asogwa,   B.C.
Following the radical reorientation of agricultural policy during the SAP years, beginning in the mid-1980's, cassava emerged as an important crop in the national effort to replace imported foods with domestic production. The policy direction of the Nigerian government has encouraged cassava development leading to a new orientation in research-extension-farmers linkage, especially in the IFAD-assisted Cassava Multiplication Programme (CMP). This study evaluated farm management dividends in a friendly policy environment: the case of cassava industry in Nigeria. Data were collected from randomly sampled 360 cassava farmers in Benue State, Nigeria using a structured questionnaire. The data were analyzed using the stochastic frontier production function.

Farm Policies and Added Sugars in US Diets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Beghin,   John C.; Jensen,   Helen H.
Major changes in the use of US sweeteners have occurred since 1970, in both the amount and composition. Increased consumption of caloric sweeteners, especially in beverages, has been linked to excess energy intake and lower-quality diets. We examine how US farm policies (specifically agricultural research and development [R&amp;D] expenditures and commodity programs) have affected the consumption and composition of sweeteners in the US diet. R&amp;D expenditures have lowered the unit cost of most commodities and increased their use in food production, ceteris paribus, although corn has benefited more than sugar crops in the technical progress. Commodity programs have raised the price of sugar and decreased the price of corn; high fructose corn syrup (HFCS)...

FARM VALUE OF TOPSOIL IN SPRING WHEAT PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Williams,   Jeffery R.; Tanaka,   Donald L.; Herbel,   Kevin L.
Relationships among topsoil removal treatments and additions of nitrogen and phosphorus fertilizer in spring wheat yields are used to determine the effects on net returns and to estimate the marginal value of soil. The results indicate that risk-averse managers are not willing to make an expenditure for controlling erosion from the first 2.5 inches of soil if the erosion rate is 20 tons/acre/year or less and the planning horizon is 20 years or less. These managers would be willing to make an erosion control investment for the second 2.5 inches of soil equivalent to $4.90 to $5.20/acre from the twenty-first to forty-third year in the planning horizon.

Farm Yields and Returns to Farmers From Seed Cotton: Does Zambia Measure Up?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kabwe,   Stephen; Tschirley,   David L.
1. Farm yields are one key indicator of the productivity of a cotton sector, and an important determinant of returns to farmers (and thus of cotton’s ability to reduce poverty) 2. Zambia’s relatively good performance on input credit provision means that it has been able to raise yields since reforms in 1994; yet the rate of increase has been slow, and yields remain well below those found in countries of West and Central Africa. 3. Average returns to farmers do not appear to be any higher in Zambia, with good performance on input credit provision, than in Tanzania, where input use and yields are low. 4. Zambia’s concentrated structure gives it the potential to substantially increase farm productivity, and for cotton to make but relatively little of this...

Farmer management of production risk on degraded lands: the role of wheat genetic diversity in Tigray Region, Ethiopia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Di Falco,   Salvatore; Chavas,   Jean-Paul; Smale,   Melinda.
This paper investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from household survey conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land degradation, and their interaction on the mean and the variance of wheat yield. Ethiopia is a centre of diversity for durum wheat and farmers manage complex variety mixtures on multiple plots. Econometric evidence shows that variety richness increases farm productivity. Variety richness also reduces yield variability but only for high levels of genetic diversity. Simulations with...

Farmer Preferences for Milpa Diversity and Genetically Modified Maize in Mexico:  A Latent Class Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Birol,   Ekin; Villalba,   Eric Rayn; Smale,   Melinda.
Maize, the second most globally important staple crop after wheat, originated in Mexico, where it is typically grown as part of a set of associated crops and practices called the milpa system. This ancient mode of production is practiced today in ways that vary by cultural context and agro-environment. Milpas generate private economic value, in terms of food security, diet quality and livelihoods, for the two-million farm households who manage them. Furthermore, milpas generate public economic value by conserving agrobiodiversity, especially that of maize landraces, which have the potential to contribute unique traits needed by plant breeders for future crop improvement. In this way, milpas contribute to global food security in maize. However, the...

Farmer Willingness to Pay for Seed-Related Information: Rice Varieties in Nigeria and Benin
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Horna,   J. Daniela; Smale,   Melinda; von Oppen,   Matthias.
A typical private good is defined by its excludability and rivalry characteristics. Information embodied in a technology might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of this kind of information and its delivery can generate incentives for private participation. This study examines farmers’ preferences for seed of new rice varieties and their willingness to pay for seed-related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers’ preferences for rice seed given a set of alternatives. Farmers are considered to be consumers of seed as a production input, preferring one variety over another based on the utility they obtain from its attributes, which...

In their continuous quest for ecologic improvements, private voluntary certification initiatives might undermine the willingness to continue of the participating farmers. In this research, the ecologic contribution and the farmers’ acceptance of changing the pesticide policy of a private certification initiative is presented. To measure the perceived farmers’ disutility, the choice preference technique is used. We can conclude that there is room for ecologic improvements but that farmers are in general change averse, primarily because of the fear that price compensation will remain largely absent.

Farmers will generally support and patronize technologies, including those that utilise genetic modification, to the extent that these reduce their costs of production, improve yields, enhance the quality and acceptability of their products, and increase their incomes and overall economic welfare. Farmers would, however, have special concerns and apprehensions regarding long-term access to GM seeds and other modern technologies of their choice, especially if proprietary rights over such technologies are controlled by and/or concentrated in a few large companies. GM technology may also turn out to be too expensive or complicated for small resource-poor farmers to use, or may not yield expected results due to the lack of support facilities and structures in...

Overall, the farmers showed a fairly good understanding of soybean aphids and their impact on soybeans. Over 80% said soybean aphids could be treated and repopulate in the same crop year. For 2004-2006, at least 75% of the farmers said aphids damaged their soybeans by sucking sap. However this percentage dropped to 59% for 2007 with a greater percentage pointing at a combination of damage methods.

Autores: Westra,   John V.; Olson,   Kent D.
In a transect survey of crop residue levels in 1995 and 1996, two Minnesota counties had very different percentages of cropland with desired residue cover even though the soil types were similar.  To gain a better understanding of the reasons behind this difference, the farmers in these two counties were surveyed about their use or lack of use of conservation tillage practices.  A statistical logit analysis of survey responses showed farmers are more apt to adopt conservation tillage if they are larger; are more concerned about erosion on their land; have made a recent major investment in the farm; use other producers for tillage information; have the management skill for conservation tillage; and believe conservation tillage will fit with their production...

The purpose of this paper is to explore into the relationships between farmers' post-harvest grain management practices/capacities on the one hand, and liquidity constraints and impending risks on the other, in the context of achieving food security objective at household and national levels. The findings are primarily based on a household survey data from 300 randomly selected major food grain producing peasant households in three rural districts of Ethiopia. Results indicate that farmers perceived post-harvest grain loss as an imminent risk, and that instant sales of grains after harvest are triggered by temporary but immediate liquidity preferences to meet various obligations in the absence of or limited sources of cash other than crops sales, and by an...

Farmers' Seed Selection Practices and Maize Variety Characteristics in a Traditionally-Based Mexican Community
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Louette,   Dominique; Smale,   Melinda.
Experimental results and farmer surveys in a Mexican community indicate that farmers’ seed selection practices protect the phenological integrity of their maize varieties as they define them, despite numerous factors contributing to genetic instability. Analysis of morphological and genetic data suggests that when subjected to significant gene flow through cross-pollination, ear characteristics are maintained through farmers’ selection even though other characteristics may continue to evolve genetically. Because the effects of farmers’ selection practices are confined largely to ear characteristics and plant characteristics that are linked to them, their practices appear to offer only limited scope for improving varieties. Farmers’ expectations of what...

Using survey responses of Illinois corn farmers to differently framed yield questions, we examine their subjective information by relating stated yields and risk to the corresponding objective county measures.  The results show that farm-level yields can be best characterized by soliciting probabilistic information, which provides more accurate yield assessments than an open-ended frame and consistent estimates of producers’ subjective risk.  Moreover, we find that overconfidence can be confused with differences in relevant information and that using recent data may be more appropriate in examining subjective risk statements.  Our results are important for agricultural policy-makers and researchers, particularly those who work with surveys that include...

Farmers' Use of Improved Seed Selection Practices in Mexican Maize: Evidence and Issues from the Sierra de Santa Marta
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rice,   Elizabeth; Smale,   Melinda; Blanco,   Jose-Luis.
The principal advantage of in situ conservation is that it allows adaptive evolutionary processes to continue in the species that are being conserved. For a cultivated crop species, in situ conservation involves farmers' management of their own genetic resources even as the farmers themselves adapt to a changing environment. Improved seed selection practices and other on-farm breeding strategies have been proposed as a means of providing economic incentives for farmers to continue growing traditional varieties or landraces identified as important for conservation. This paper describes a pilot study among a group of indigenous farmers in the Sierra de Santa Marta, Veracruz, Mexico, who have collaborated in such efforts. The findings raise key issues about...

Farmers' Willingness to Grow Cover Crops:  Examining the Economic Factors of Adoption in Alabama
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bergtold,   Jason S.; Fewell,   Jason E.; Duffy,   Patricia A.
The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. The literature has shown that cover crops can improve soil conservation and productivity, potentially improving cash crop yields and decreasing cash crop production costs. Farmers will adopt cover crops if the net economic benefit of utilizing them is positive. This study examines farmers’ willingness to grow cover crops as a soil conservation practice and to examine the socio-economic factors affecting their decision. Survey data collected in 2007-8 from Alabama farmers about cover crop adoption and management is utilized to estimate a cover crop adoption model.

Farmers’ Willingness to Grow Sweet Sorghum as a Cellulosic Bioenergy Crop: A Stated Choice Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bergtold,   Jason S.; Fewell,   Jason E.; Williams,   Jeffery R.
Biofuel production must increase to 36 billion gallons by the year 2022, according to government mandates. The majority of this fuel must be produced from “advanced” or second-generation biofuel feedstocks after 2015. Advanced biofuel feedstocks include annual crops such as sweet sorghum. Kansas farmers are poised to be major producers of sweet sorghum for biofuels. A stated choice survey was administered to Kansas farmers to assess their willingness to grow sweet sorghum for biofuels under various contracting scenarios. Results show that farmers are willing to grow biomass for bioenergy under contract and that insurance availability plays an important role in their decision.

Farmers’ Willingness to Grow Switchgrass as a Cellulosic Bioenergy Crop:  A Stated Choice Approach  Agriculture’s role as a source of feedstocks in a potential lignocellulosic-based biofuel industry is a critical economic issue. Several studies have assessed the technical feasibility of producing bioenergy crops on agricultural lands. However, few of these studies have assessed farmers’ willingness to produce or supply bioenergy crops or crop residues. Biomass markets for bioenergy crops do not exist, and developing these markets may take several years. Therefore, an important, yet unaddressed question is under what contractual or pricing arrangements farmers will grow biomass for bioenergy in these nascent markets.

Autores: Pushkarskaya,   Helen N.; Vedenov,   Dmitry V.
This article analyzes factors that affected the decision to exit tobacco production in the wake of the tobacco buyout program using the data collected through a survey of Kentucky tobacco farmers. Using the Heuristic logistic regression model, we find that the decision to exit tobacco growing was affected by efficiency considerations, availability of off-farm employment, and exit barriers. Availability of off-farm employment had the strongest effect on farmers younger than 46, while the effect of variables measuring efficiency and exit barriers seemed to be more uniform across age groups. Based on the results we suggest several policy interventions.

FARMING FOR ETHICS: AN EXAMINATION OF THE ETHICAL CHALLENGES OF MISSOURI CORN AND SOYBEAN PRODUCERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: James,   Harvey S., Jr.
Interviews with Missouri corn and soybean farmers reveal what farmers feel are the most important ethical challenges in agriculture. In contrast to the literature, which characterizes ethical challenges in term of philosophical debates about soil conservation, the use of pesticides and genetically modified seeds, or the treatment of animals, for instance, this research finds that farmers perceive ethical challenges in behavioral terms. The reason is rooted in the industrialization of agricultural production, which creates tensions for farmers between doing what they believe to be right and doing what they feel they must in order to survive.

Acid and acidifying soils occur extensively in Australia. Currently, some 90 million hectares of agricultural land in Australia is considered to be acidic and around 35 million hectares are considered to be highly acidic which is both a serious agricultural and environmental problem. The nature, impact, and causes of soil acidification vary across Australia, as do farming systems and the institutional and socioeconomic issues relating to land management. In high-rainfall areas of south-eastern Australia, managing acid soils is particularly difficult in permanent pasture systems.

This study, based on the data of China’s agricultural census of 1997, focuses on the land distribution among rural households and its effects on crop production structure and employment of labor and capital. The Census data show that the size of holdings surprisingly differs among households, and land rental activities has started to play an important role in land allocation. Grain production accounts for 80% of total sown area for each household group, indicating that self-sufficiency in grains production is still an important factor to farmers. Family members are a dominant source for China's agricultural labor force, regardless of the size of land held in each household. Machinery use in crop production is still not popular, while the scale of land held...

FARM-LEVEL EFFECTS OF ADOPTING HERBICIDE-TOLERANT SOYBEANS IN THE U.S.A.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fernandez-Cornejo,   Jorge; Klotz-Ingram,   Cassandra; Jans,   Sharon.
This paper estimates the on-farm impacts of adopting herbicide-tolerant soybean on herbicide use, yields, and farm profits, using an econometric model that corrects for self-selection and simultaneity and is consistent with profit maximization.  The model is estimated using nationwide farm-level survey data for 1997.  Given that the use of herbicide-tolerant soybeans involves the substitution of a particular herbicide - primarily glyphosate - for other herbicides, we explicitly consider this substitution process in the model.

FARM-LEVEL INCENTIVES FOR FERTILIZER USE IN RWANDA'S KIGALI RURAL PROVINCE: A FINANCIAL ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mugabo,   Josaphat R.
The objective of this study was to evaluate the profitability of the main food crops in the context of the current government policy of promoting the use by farmers of improved inputs. This study tried to estimate the magnitudes of costs associated with the use of chemical fertilizer on climbing beans, maize, sorghum and soybeans grown in the province of Kigali rural and the benefits farmers would get by investing their labor and money in these crops. In less detail, this study analyzed some recent survey data seeking to put crop production in a wider perspective of the household's limitations and/or opportunities when dealing with the issue of improving crop yields on its land. Data analysis was done at the agroecological zone level and considered the...

Feasible Fumigant-Herbicide System Alternatives to Methyl Bromide for Bell Pepper Producers
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Byrd,   Mark M.; Escalante,   Cesar L.; Fonsah,   Esendugue Greg; Wetzstein,   Michael E.
With the current methyl bromide (MeBr) system for producing Georgia’s peppers being phased out, alternative fumigant and herbicide systems for producers are analyzed. Using stochastic dominance analyses, two alternatives exceeding MeBr’s yield and financial efficiency were identified. A programming model, incorporating simulation-optimization techniques, generated optimal production and financial plans. Results indicate potential economic viability under alternative systems vis-à-vis the traditional MeBr production system. The Telone II and Chloropicrin combination with Metham potassium may offer a viable substitute for MeBr.

Feed versus Food: The Future Challenge and Balance for Farming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zhou,   Zhang-Yue.
Demand for livestock products in the past three decades has increased rapidly, especially in developing countries. This increase has resulted in, and will continue to cause, increased demand for livestock feed. This paper examines existing projections of global feed demand and supply with an emphasis on China. It first presents the emerging trends in demand for feed and food, followed by global perspectives of feed demand and supply. It then highlights the challenges facing future farming in its endeavour to meet the increasing demand for feed. Finally, the paper sheds light on whether the livestock revolution will offer much opportunity to farmers, especially small farmers in the developing countries and those at home in Australia.

Feeding the Factory Farm: Implicit Subsidies to the Broiler Chicken Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Starmer,   Elanor; Witteman,   Aimee; Wise,   Timothy A.
Since the passage of the 1996 Farm Bill, the U.S. market prices of soybeans and corn have dropped 21% and 32%, respectively. These commodities are sold on the market at a price below what they cost to produce. If U.S. agricultural policies contribute to this trend, then they do so to the benefit of commodity purchasers, particularly the industrial operations that use the commodities as raw material inputs. Corporate-owned livestock operations are a case in point. This paper focuses on the broiler chicken industry, which, in the United States, is fully industrialized and vertically integrated. We compare the average costs of production for broiler feed components—corn and soybean meal—with market prices, and then use these cost-price margins to estimate the...

Fertilization: trade-offs between manure abatement and plant productivity

Autores: Van der Straeten,   Bart; Buysse,   Jeroen; Marchand,   Fleur L.; Lauwers,   Ludwig H.; Claeys,   Dakerlia; Van Huylenbroeck,   Guido.
In 2005, 30% of the Flemish farms faced a manure excess, while at aggregated level still 9.7% of the emission rights were unused. This means that, despite the various possibilities, Flemish farmers do not succeed in an effective exchange of manure between farms. In current paper is shown how inorganic fertilizer use influences the use and exchange of organic nitrogen. Because of the mutual interdependency between organic and inorganic nitrogen emission rights (or quota), inorganic nitrogen use limits the emission rights for organic nitrogen. Utilisation of these emission rights are analysed as a trade-offs choice between plant productivity (use of inorganic nitrogen) and manure disposal, as the major abatement alternative of manure production. Farmers...

Several past studies used time series data to estimate price elasticities of demand for fertilizer or nutrient use on all crops in the United States or by region. In this study, demand functions for nitrogen, phosphorous and potassium applied per acre of corn, wheat and soybeans in the United States were estimated, using a combination of autoregressive least squares and seemingly unrelated regression techniques. The results suggest that the demands for nitrogen, phosphorous and potassium applied to corn are price elastic, while similar responses for wheat and soybeans are price inelastic. Nitrogen and phosphorous applied per acre of corn were found to be positively related to government sponsored acreage diversion. The estimated elasticities could provide...

Fertilizer Impacts on Soils and Crops of Sub-Saharan Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Weight,   David; Kelly,   Valerie A.
Successful agricultural development has resulted in substantial alleviation of poverty and food security in Asia and Latin America since the 1960s. Much of this success can be attributed to the introduction of high-yielding varieties of crops, especially wheat and rice, which have addressed the constraints faced by farmers using traditional varieties. In Sub-Saharan Africa (SSA), however, productivity levels have remained stagnant despite the introduction of new crop germplasm. In recent years, scientists have recognized that low soil fertility is the primary constraint blocking agricultural development in SSA. Major findings from this study may be summed up in five key points. Declining fertility and SOM in SSA are a result primarily of...

FERTILIZER MARKET REFORM AND THE DETERMINANTS OF FERTILIZER USE IN BENIN AND MALAWI
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Minot,   Nicholas; Kherallah,   Mylene; Berry,   Philippe.
Most countries in sub-Saharan Africa have reduced or eliminated fertilizer subsidies and liberalized input marketing as part of the reform process that began in the early 1980s. The effect on fertilizer prices and use is one of the most frequently mentioned criticisms of liberalization. The effect of these reforms, however, has varied widely across countries. For example, in Benin fertilizer use has increased ten-fold since 1982, while in Malawi it has risen just 30 percent, less than population growth over the period. This paper explores the factors behind these widely different experiences with input market reform. It relies in part on household survey data collected by IFPRI and collaborating institutions in 1998. The two surveys used nationally...

Fertilizer Use and Maize Production in Sub-Saharan Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Heisey,   Paul W.; Mwangi,   Wilfred.
In sub-Saharan Africa, greater use of mineral fertilizers is crucial to increasing food production and slowing the rate of environmental degradation. Regional growth rates in fertilizer consumption have never been particularly high, in part because the real price of fertilizer is higher in Africa than in many other developing regions. As subsidies have been removed and exchange-rate distortions corrected over the past decade or more, relative prices paid by farmers have risen to reflect more closely the economic cost of fertilizer. Consumption growth has thus slowed even more.  Nonetheless, during the period of declining growth in consumption, fertilizer use on cereals, particularly maize, has become relatively more important than use on cash crops....

This study presents recent results on the impact of adopting Bt corn on farm profits, yields, and seed and insecticide use.  The study employs an econometric model that corrects for self-selection and simultaneity and uses farm-level survey data for 2010.  Results confirm previous findings that Bt adoption is associated with increased profits and yields. However the Bt adoption is not significantly related to insecticide use as infestation levels in 2010 are very low and 90 percent of the farmers in the sample did not use insecticides at all.

Fiji's Sugar Woes: The Challenge of the Land Tenure System, Ethnicity and the Erosion of EU Sugar Preferences
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mahadevan,   Renuka.
The non-renewal of land leases since 1997 and the impending withdrawal of the European Union’'s sugar preferences in 2007 have created major uncertainties in Fiji’'s sugar industry. In the context of this troubled environment, this paper examines the impact of various socio-economic factors on the viability of the industry by focusing on farm efficiency in sugar cane production. It was found that, in general, farmers were inefficient and produced 25% less than their potential output. Among the farm inputs, land (labour) was relatively the most (least) efficiently used input. Empirical evidence also suggests that the more productive Indian farmers rather than the natives be left to farm cane and that large scale farming should be seriously considered by...

This paper presents a financial and risk analysis of improved versus traditional maize production technology in Ethiopia, based on yields simulated with the CERES-Maize crop growth model (Schulthess and Ward, 2000). The purpose is to analyze the potential performance of the SG2000/Ministry of Agriculture program technology under less favorable meteorological conditions (rainfall level and distribution), and in areas with lower agroecological potential than those covered by the SG2000/MOA program through 1998. At the time of this study, expansion of the MOA program into lower potential zones seemed likely. Results show that use of fertilizer and improved seed is highly profitable under a variety of assumptions about crop growth conditions, maize prices, and...

For the last three years, U.S. cotton producers have been heavily dependent on ad hoc emergency disaster and market loss assistance to cash flow their operations. They have not been alone. Wheat, feed grains, oilseeds and rice producers have also been faced with low commodity prices, adverse weather and the need for substantial government assistance. Price support and direct payments by CCC for fiscal years 1998-2000 averaged $17.5 billion per year (USDA Ag Outlook). Has U.S. program crop agriculture turned the corner or will additional government payments likely be needed to sustain a vulnerable sector?

The high costs of rehabilitating and/or expanding government-managed irrigated schemes in Mali (Office du Niger) has prompted policy-makers and researchers to explore the potential for the underdeveloped farmer-managed bas-fond  to contribute to ensure an adequate rice supply and increase rural households' incomes.  Because little is known about nas-fond rice production in Mali, this paper analyzes its financial profitability based on data collected from a random sample of 221 farmers.  Data analysis revealed that there are numerous rice production systems in the bas-fond.  Budget analysis showed that the four most common bas-fond production systems yield higher returns than the opportunity cost of labor and they are more profitable than the main upland...

Autores: Hewavitharane,   H.V.C.; Warnakulasooriya,   H.U.; Rafeek,   M.I.M.
Delays in payment adversely affect the contract seed production program for other field crops (OFC) conducted by the Department of Agriculture (DOA) Sri Lanka. This study focuses on assessing the financial viability of advancing payments for contract farmers who produces groundnut (Arachis hypogaea L.) seeds. The average price payable to contract growers for the Seed and Planting Material Development Centre(SPMDC), to be break even between the current practices of paying after the processing is over and advancing payment, was estimated using an Expected Value Model (EVM). Proportions of grade I and grade II seed and the price payable for each seed lot were estimated incorporating parameter estimates of “A” reports in a regression model. The average price...

Financing agricultural inputs in Northern Togo through an inventory credit system: an economic analysis of institutional response
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Konlambigue,   Abdou.
Agricultural intensification is widely seen as a condition sine-qua-non for enhanced food security and as a major driver for overall economic growth in sub-Saharan Africa (SSA). In this process, the financial system has an important role to play, especially to finance agricultural inputs. However in SSA, the financial institutions initiated by governments and donors have in general not lived up to the expectations, in particular not for the agricultural sector, because of inappropriate design and weaknesses in implementation. Even the microfinance institutions which were supposed to support the small-scale farmers have deflected for their goals due to the risks that the agricultural sector represents. To date, the economic research tends to concentrate on...

Finding a sustainable linkage between the emerging farmer and formal markets: The case of pick ‘n pay and the Zanyokwe farmers in the eastern Cape of South Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bediako,   J.A.; Debrah,   Kofi.
A major problem confronting rural and emerging farmers is the marketing of their products. Most of the farmers encountered depend on the local or village markets which are often saturated or purchases are not backed by effective demand to make sales meaningful for the desired benefits. Small scale South African farmers have not been able to access the formal sector to sell their goods. There are several reasons for this which is linked to the nature of the historical evolution of the South African agricultural sector and in particular the food production system. Recently, it has been argued that the small scale farmers are not able to meet the standards that are set by the formal sector and are therefore responsible for their own exclusion by producing...

FIRM EFFICIENCY AND INFORMATION TECHNOLOGY USE: EVIDENCE FROM U.S. CASH GRAIN FARMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hopkins,   Jeffrey W.; Morehart,   Mitchell J.
We implement stochastic frontier analysis techniques to show the effects of information technology use on firm efficiency.  Results from a sample of 1,865 U.S. cash grain farms reveals that information technology use within the farm business moved farms significantly towards the efficiency frontier.  Also moving farms towards the  efficiency frontier were the use of written long-term plans, advanced input acquisition strategies, and increased farm labor hours relative to total labor hours.  In contrast, an increase in the debt to asset ratio was associated with movements away from the efficiency frontier.

FLEXIBLE, RISK-ORIENTED MARKETING STRATEGIES FOR PINTO BEAN PRODUCERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: King,   Robert P.; Lybecker,   Donald W.
A model designed to identify preferred postharvest marketing strategies for pinto bean producers is presented. The model evaluates flexible strategies that use current market information to determine whether or not storage should continue.  Explicit consideration is given to price uncertainty and risk preferences.  The results indicate that nearly all decision makers prefer flexible strategies to fixed strategies that call for a predetermined pattern of sales.  They also show that the choice of a marketing strategy is sensitive to risk preferences.  Initial experiences in making the model available to producers are also discussed.

Floricultural production contains a wide variety of products. The production value world wide has been rising from 11 billion to 60 billion dollars in 2003 (estimate). Europe is traditionally a large producer and trader, with a stable production value of about 10 billion dollars (2002). North America has a production value of about 6,5 billion dollars. In Asia production capacity is growing rapidly in several countries. In Africa the production has emerged enormously, but in a risky environment. Oceania is a small producer. Looking a inter- and intra continental trade in 2002 the following view occurs. Europe and USA have the largest intra continental trade. Latin America, Africa, Asia and Europe export to these continents. Of the existing markets USA has...

Florida Agriculture and the Vegetable Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Stevens,   Thomas J., III; Hodges,   Alan W.; Mulkey,   W. David.
Florida ranked ninth in the U.S. in agricultural receipts for the year 2000, and ranked first or second in receipts for 12 of the nation's top 25 agricultural commodities. Ten of these twelve leading agricultural commodities were fresh fruits or vegetables, and combined, they represented over 45 percent of the state's agricultural receipts in 2000. Despite Florida's preeminent standing as a producer of fresh fruits and vegetables, it's future leadership in this industry is less clear. In real terms, Florida's annual agricultural receipts have declined from $7.41 billion in 1992, to $6.42 billion in 2001. In 2000, receipts fell by over $521 million, the sharpest one-year drop since 1990. The overall trend in fresh vegetable receipts for the State has been...

Food Pricing Policy and Rural Poverty: Insights from Maize in Kenya
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mghenyi,   Elliot W.; Jayne,   Thomas S.
This study estimates the effects on poverty resulting from maize price changes associated with the operations of the maize marketing board in Kenya. We consider both supply and demand responses and the accompanying adjustments in rural labor markets in estimating a second order approximation to equilibrium income changes. We then use stochastic dominance techniques to generate poverty rankings between the distribution of income with the effects of the government marketing operations and the distribution of counterfactual incomes. This approach effectively addresses concerns regarding the sensitivity of poverty estimates to the type of poverty measure used. Results indicate that the price-elevating effects of government maize marketing operations have...

We use the mean value and variation coefficient model to analyze the spatial-temporal feature of grain production in 31 provinces from the year 1980 to 2006.  Time series of grain production is divided into 3 stages according to the average yield and the variation coefficient of grain production in provincial level, which are the lower yield and higher variation stage, the higher yield and lower variation stage and the higher yield and higher variation stage.  We classify the grain production of each province into four types according to the grain production level and the annual variation characteristics: the lower yield and higher variation type, the lower yield and lower variation type, the higher yield and lower variation type and the higher yield and...

This paper examines potential of contract farming as a rural development tool by revealing its effect on productivity and income of small holders in tea production in north-western Vietnam. In the present research, three economic analyses are applied. First, the technical efficiency of tea production is estimated by using stochastic frontier model. The results show that contract farming achieved significantly higher technical efficiency compared to non-contract farming. Second, logit model is investigated to determine the influential socio-economic characteristics of households for contract participation. The model indicates that social relationship of households, such as the membership in the communist party, play an important role in contract...

Food security in Uganda: a dilemma to achieving the millennium development goal
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ssewanyana,   Sarah N.; Kasirye,   Ibrahim.
The status of food security in Uganda is worrying. The share of Ugandans suffering from food insecurity measured in terms of caloric intake is alarmingly high with low rates of income poverty. Based on the 2005/06 Uganda National Household Survey data, the study provides insights into access to food at household level. More importantly, the study shows that average caloric intake stood at 1,970 calories per person per day, which is below the minimum caloric requirement of 2,200 calories. As such, a population of 17.5 million Ugandans in 3.1 million households were unable to meet the minimum caloric requirement in 2006. This raises questions on whether Uganda will be able to achieve the Millennium Development Goal (MDG) 1: halving extreme poverty and hunger...

Foodgrain Supply, Distribution, and Consumption Policies within a Duel Pricing Mechanism: a Case Study of Bangladesh
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ahmed,   Raisuddin.
Conflict between the short run welfare of poor consumers and agricultural production incentives creates some of the most difficult policy issues facing developing countries. Resulting policy option constraints are particularly severe in very low income countries. The conflict may on the one hand impede the growth in al production essential to improve long term welfare of low income consumers, and on the other hand restrain policies to increase consumption, which in the long run is essential to the success of the measures taken to increase production. The widely observed phenomenon of urban bias in food price policy is itself a product of the nature of low income societies and of this complex conflict.  This research by Raisuddin Ahmed delineates and...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Duke,   Jason C.; Epplin,   Francis M.; Vitale,   Jeffrey D.; Peel,   Derrell S.
Winter wheat may be grown in the Southern Plains either to produce grain only, or as a dual-purpose crop to produce both fall-winter forage and grain. The objective of the research is to determine expected net returns for both production systems. The estimated expected net value of the dualpurpose system stocked with steers with an initial weight of 450 pounds is from $38 to $92 per acre greater than that of the grain-only system. The economic success of dual-purpose wheat depends on a number of management factors including stocking density.

FORECASTING CROP QUALITY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ryland,   G.J.
The need for a forecasting system of biological quality arises as a result of the price-quality payment schemes in grower and processor contracts which operate in many agricultural cropping industries. The seasonal nature of the series of vertical quality height gives rise to questions as to the repetitive pattern of the shape and trend translation of the series. These hypotheses can be tested using conventional statistical methods. For non-stationary series, however, a Box-Jenkins type dynamic seasonal model is proposed. These forecasting procedures are applied to a series of sugar cane quality.

Autores: Poonyth,   Daneswar; van Zyl,   Johan; Meyer,   Ferdinand H.
In this study, an econometric model of the South African maize and sorghum sector is estimated. Using the developed model, a market outlook for the two major grain sectors – maize and sorghum - for 1999/00 to 2006/07, is generated under the specified assumptions. Results indicate that for both maize and sorghum, consumption will gradually increase over time. In spite of varying areas of maize and sorghum being harvested, total production will also gradually increase over time due to increases in particularly yields.

Forecasting World Crop Yields as Probability Distributions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ferris,   John N.
Traditionally, agricultural forecasts, whether for the coming year or several years into the future, have been based on assumptions of normal weather and trend crop yields.  That weather is seldom normal and that yields seldom fit trends are well recognized.  However, relatively little attention has been given to projecting crop yields stochastically even though computer capacity and software programs are available to do so.  One reason is that the task is more challenging than to assign standard deviations to various crop yields and simulate normal distributions using random number generators.  For one, deviations of crop yields from trends may be correlated especially if the locations of the crops overlap such as is the case with US corn and soybeans....

Autores: Dhakal,   Bhubaneswor; Bigsby,   Hugh R.; Cullen,   Ross.
Common forests in developing countries are valuable sources of raw material supplies, employment and income generation, particularly for low income households. This paper looks at the effect on income and employment when common forest resources have external policies that constrain their use. Using a mixed-integer linear programming model, this study examines the impacts of conservation-oriented community forest policies in Nepal on three household income groups. The results show that current community forest policies, which focus on environmental outcomes through forest use restriction for environment conservation and timber production, result in a large reduction in employment and income of the poorest households and largely explain the recent increase...

By 2019, Russia could become the world’s top wheat exporter, and Russian, Ukrainian, and Kazakhstan wheat exports collectively could more than double those of the United States. Growth in the former Soviet Union’s grain production and exports may increase world food availability and, in the near term, help mitigate global food security concerns. U.S. wheat production is leveling off, as U.S. producers shift acreage to benefit from competitive advantages in corn and soybeans.

Autores: Davis,   Todd D.; Patrick,   George F.; Coble,   Keith H.; Knight,   Thomas O.; Baquet,   Alan E.
Forward pricing behavior of random samples of Indiana, Nebraska, and Mississippi crop producers was analyzed using Heckman’s two-step limited information maximum likelihood estimation procedure.  Producers who forward priced during the 1995-1998 period generally expected to forward price in 1999 using similar techniques.  Probit models were estimated for cash forward contracts and taking a direct position in futures or options separately and combined.  Results provide limited support for the hypothesis that forward pricing should be analyzed as an adoption decision.  Variables reflecting risk attitudes do affect the decision to use forward pricing, while variables to economic position affect the level of forward  pricing.

FORWARD SHIPPING OPTIONS FOR GRAIN BY RAIL: A STRATEGIC RISK ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Priewe,   Steven R.; Wilson,   William W.
Grain hauling railroads began offering shipping alternatives in the late 1980s that have made transportation decisions more strategic. Shippers now confront alternatives ranging from nearby and unguaranteed ordering to various durations of forward and guaranteed shipment.  A dynamic stochastic simulation model was developed to analyze grain shipping and merchandising strategies that integrate these alternatives.

Grain hauling railroads began offering shipping alternatives in the late 1980s that have made transportation decisions more strategic. Shippers now confront alternatives ranging from nearby and unguaranteed ordering to various durations of forward and guaranteed shipment.  A dynamic stochastic simulation model was developed to analyze grain shipping and merchandising strategies that integrate these alternatives.

FQPA IMPLEMENTATION TO REDUCE PESTICIDE RESIDUE RISKS: PART I: AGRICULTURAL PRODUCER CONCERNS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Batie,   Sandra S.; Swinton,   Scott M.; Schulz,   Mary A.
The Food Quality Protection Act of 1996 (FQPA) transforms the regulation of pesticide residues on food in the United States.  Three changes are prominent.  First, under the FQPA, the U.S.  Environmental Protection Agency (EPA) is authorized to develop uniform pesticide residue tolerances for both fresh and processed foods.  These tolerances must be based on a conservative standard appropriate for infants and children, rather than the adult-based tolerances that prevailed previously for fresh-market produce.  Second, under the FQPA, pesticide registration will be based upon aggregate risk to the most susceptible consumers from all pesticides sharing a common biochemical mode of action in humans.  Third, the FQPA expands the scope of health effects included...

FQPA IMPLEMENTATION TO REDUCE PESTICIDE RESIDUE RISKS: PART II: IMPLEMENTATION ALTERNATIVES AND STRATEGIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Swinton,   Scott M.; Batie,   Sandra S.; Schulz,   Mary A.
Implementation of the Food Quality Protection Act (FQPA) is fraught with difficulty due to the divergent perspectives and demands of stakeholders in the process.  In "Part I: Agricultural Producer Concerns," the authors reviewed the concerns of food producers about potential FQPA threats to farm profitability, international competitiveness, consumer perceptions, and the development of pest resistance to remaining pesticides.   Fortunately, lessons from past environmental policy and economic theory offer useful principles for how to implement the FQPA.  This paper, "Part II: Implementation Alternatives and Strategies" addresses ways to accommodate producer concerns while meeting the policy mandate of reducing risk from pesticide exposure, especially for...

Framework and Initial Analyses of Fertilizer Profitability in Maize and Cotton in Zambia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Donovan,   Cynthia; Damaseke,   M.; Govereh,   Jones; Simumba,   D.
The main question which this research originally sought to answer was whether or not inorganic fertilizers are generally profitable used alone on maize, or with pesticides on cotton, for small farmers in Zambia. Rather than give a definitive answer for each Zambian farmer, the authors developed a framework for analysis and applied that framework to locations with sufficient information. Using simple value/cost ratios, researchers estimated the potential profit of fertilizer for those sites. Then, using the distributions of response rates of the crops (incremental yields) found in the trials and output prices based on regional price series, the probabilities are estimated for VCRs, using a minimum of VCR of 2.0 for profitability. The results for selected...

FREEZE RISK AND ADOPTION OF TECHNOLOGY BY ORANGE PRODUCERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schmitz,   Andrew; Rimal,   Arbindra.
Orange producers in many regions of the U.S. are affected by the recurrence of frost.  This study evaluated 147 California farmers' perceptions of frost risk relative to other business risks.  Freeze risk perception was negatively related, for example, to farm size.  Large farmers with diversified businesses had lower perceptions of freeze risk than small farmers.  Change in crop location and the adoption of anti-frost technology were two important responses to freeze risk.  California farmers shifted their location to frost-prone areas and adopted anti-frost technology.  Florida farmers, however, diversified to less frost-prone areas and adopted new planting technologies instead of anti-frost technologies. Key words: anti-frost technologies,...

Fresh Grapefruit Supply-Chain Adjustments: Consolidation in Produce Packing?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Thornsbury,   Suzanne; Davis,   Kathy J.; Ward,   Ronald W.
This study evaluates long-term structural adjustments in fresh grapefruit packing under aggregate market pressures, including those from retail concentration. While individual firms enter and exit, Markov-model results are indicative of an industry near equilibrium with little expectation of change in the distribution of firm sizes given existing patterns of sector adjustment. Estimation of Lorenz curves and corresponding Gini coefficients fully support Markov analysis findings. Lags in the packing sector adjustment process in the face of sweeping forces of change in fresh produce markets are likely to put this sector at a relative disadvantage within the supply chain.

From Ecology to Economics: The Case Against CO2 Fertilization
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Erickson,   Jon D.
The effects of increasing concentrations of atmospheric carbon dioxide (C02) on agricultural yields are analyzed. It is argued that any positive effects on yields from C02 fertilization, demonstrated in controlled experiments, would be weak in farm conditions given water and nutrient limits. Furthermore, possible benefits would be more than offset by predicted consequences of climate change, ozone depletion, and additional gases created from fossil fuel combustion. The impact of including C02 fertilization on crop yield and economic welfare predictions is evaluated. The policy distorting potential of fragile claims is stressed

From Kyoto to Copenhagen: Meeting the Climate Change Challenge
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gaisford,   James D.
In spite of some superficial success in achieving its overall global target, there has been much disillusionment with the progress on climate change since the Kyoto Protocol was negotiated in 1997. The key problems in addressing GHG emissions under the Kyoto Protocol have been the incomplete coverage across countries and lack of credibility. While significantly more onerous reduction commitments should be expected and required of developed countries in the name of economic fairness, GHG emissions must also be capped effectively in developing countries.

Fruit and Vegetables, and the Role They Have Played in Determining the EU’s Aggregate Measurement of Support
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Swinbank,   Alan.
In its periodic declarations of domestic support to the WTO, the EU has progressively reduced its amber-box declarations in line with its changing system of farm support. Surprisingly, however, in 2007/08 it managed to more than halve its amber box compared with that of the previous year, easily achieving the reduction targets being touted in the Doha Round. This was largely due to a change in the calculations for fresh fruits and vegetables. These had been linked to the entry price system, which was not affected by the 2008 fruit and vegetables reform. Why the EU chose to make this change during the ongoing Doha Round negotiations remains unclear.

Fruit Flies: Solutions to Food Crop Losses and Opportunities for Business Development
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Drew,   Dick.
Fruit flies are the major insect pests of fruit and vegetable production, worldwide. In developing countries, fruit crop losses are so large that they contribute significantly to reduced household food security, poor human nutrition and poverty. In addition to the direct crop losses, many countries lose export trade opportunities if they have major pest fruit fly species, while others spend considerable sums on quarantine detection and eradication procedures in order to remain free of fruit fly. Indeed, fruit flies rate with some of the major animal diseases in terms of economic losses and quarantine problems.

Fruit flies are a serious economic pest affecting horticultural production world-wide. Increasing coordination of activities between neighbouring countries and those countries involved in fresh fruit trade is leading to more effective regional management of the fruit fly pest.  1.1 ACIAR Research Projects.   ACIAR has supported fruit fly research in developing countries since 1984. Two projects, based in Thailand and Malaysia, have generated significant scientific and economic outcomes. The total cost of these two projects was $1.7m (in 1996 dollars). Specific outcomes include: 1. A more detailed understanding of exotic fruit fly species, their host range, pest status and spatial distribution; 2. Increased interest in fruit fly management in Thailand and...

Fruit Policies in Japan
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ito,   Kenzo; Dyck,   John H.
Government programs and subsidies regulate and support Japan’s large fruit-production sector, bolstering farm incomes and output levels. Supply-management programs that target annual production levels for some fruits, in order to maintain market prices, contribute to higher prices for consumers, although other programs aim to increase fruit consumption. Japan’s tariffs and phytosanitary measures also create barriers to fruit consumption and limit imports. Producers in the United States, a major fruit supplier to Japan, could benefit from reduced barriers.

Fruit production forecasting by neuro-fuzzy techniques
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Atsalakis,   George S.; Atsalakis,   Ioanna G.
Neuro-fuzzy techniques are finding a practical application in many fields such as in model identification and forecasting of linear and non-linear systems. This paper presents a neuro-fuzzy model for forecasting the fruit production of some agriculture products (olives, lemons, oranges, cherries and pistachios). The model utilizes a time series of yearly data. The fruit forecasting is based on Adaptive Neural Fuzzy Inference System (ANFIS). ANFIS uses a combination of the least-squares method and the backprobagation gradient descent method to estimate the optimal food forecast parameters for each year. The results are compared to those of an Autoregressive (AR) model and an Autoregressive Moving Average model (ARMA).

Crop rotations and soil-management practices on a random sample of mixed crop and livestock properties on the North- Western Slope were discussed in the last issue of this journal. The survey on which the latter article was based was carried out in March, April and May, 1952, and seventy-six farmers were visited in the shires of Peel, Liverpool Plains, Macintyre and Yallaroi. As the survey was concerned mainly with practices on wheat farms, the sample was drawn from important wheat-growing districts in different parts of the North Western Slope.  The first article included an analysis of the influence of the size of farms and different soil types on the cropping practices adopted throughout the area. In order to compare the practices of holdings of...

El objetivo de esta investigación es determinar la perspectiva de la producción de trigo en la región del Bajío (Guanajuato, México), como una zona estratégica para proveer la materia prima que requiere la industria molinera de la zona centro del país. Se determinó el comportamiento de los componentes de la producción mediante el cálculo de las tasas de crecimiento. Asimismo, se elaboró un diagnóstico de la situación actual de la productividad, para lo cual se realizó una encuesta en una muestra representativa de los productores de la región. Para determinar las fuentes de inestabilidad del ingreso del productor, se utilizó el análisis de medidas de variación (coeficientes de variación, varianzas y covarianzas). Se modeló una función de producción del tipo...

Generating Global Crop Distribution Maps: From Census to Grid
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: You,   Liangzhi; Wood,   Stanley; Wood-Sichra,   Ulrike.
In order to evaluate food security, technology potential and the environmental impacts of production in a strategic and regional context, it is critical to have reliable information on the spatial distribution and coincidence of people, agricultural production, and environmental services. This paper proposes a spatial allocation model for generating highly disaggregated, crop-specific production data by a triangulation of any and all relevant background and partial information. This includes national or sub-national crop production statistics, satellite data on land cover, maps of irrigated areas, biophysical crop suitability assessments, population density, secondary data on irrigation and rainfed production systems, cropping intensity, and crop prices....

Generating Plausible Crop Distribution and Performance Maps for Sub-Saharan Africa Using a Spatially Disaggregated Data Fusion and Optimization Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: You,   Liangzhi; Wood,   Stanley; Wood-Sichra,   Ulrike.
Agricultural production statistics reported at country or sub-national geopolitical scales are used in a wide range of economic analyses, and spatially explicit (geo-referenced) production data are increasingly needed to support improved approaches to the planning and implementation of agricultural development. However, it is extremely challenging to compile and maintain collections of sub-national crop production data, particularly for poorer regions of the world. Large gaps exist in our knowledge of the current geographic distribution and spatial patterns of crop performance, and these gaps are unlikely to be filled in the near future. Regardless, the spatial scale of many sub-national statistical reporting units remains too coarse to capture the...

GENERATING PLAUSIBLE CROP DISTRIBUTION MAPS FOR SUB-SAHARA AFRICA USING SPATIAL ALLOCATION MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: You,   Liangzhi; Wood,   Stanley; Wood-Sichra,   Ulrike.
Spatial data, which are data that include the coordinates (either by latitude/longitude or by other addressing methods) on the surface of the earth, are essential for agricultural development. As fundamental parameters for agriculture policy research agricultural production statistics by geopolitical units such as country or sub-national entities have been used in many econometric analyses. However, collecting sub-national data is quite difficult in particular for developing countries. Even with great effort and only on regional scales, enormous data gaps exist and are unlikely to be filled. On the other hand, the spatial scale of even the subnational unit is relatively large for detailed spatial analysis. To fill these spatial data gaps we proposed a...

GENETICALLY ENGINEERED CROPS FOR PEST MANAGEMENT IN U.S. AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fernandez-Cornejo,   Jorge; McBride,   William D.
Adoption of genetically engineered crops with traits for pest management has risen dramatically since their commercial introduction in the mid-1990's.  The farm-level impacts of such crops on pesticide use, yields, and net returns vary with the crop and technology examined.  Adoption of herbicide-tolerant cotton led to significant increase in yields and net returns, but was not associated with significant changes in herbicide use.  On the other hand, increase in adoption of herbicide-tolerant soybeans led to small but significant increases in yields, no changes in net returns, and significant decreases in herbicide use.  Adoption of Bt cotton in the Southeast significantly increased yields and net returns and significantly reduced insecticide use.

Autores: Sobolevsky,   Andrei; Moschini,   GianCarlo; Lapan,   Harvey E.
We develop a new partial equilibrium, four-region world trade model for the soybean complex comprising soybeans, soybean oil, and soybean meal. In the model, some consumers view genetically modified Roundup Ready (RR) soybeans and products as weakly inferior to conventional ones; the RR seed is patented and sold worldwide by a U.S. firm; and producers employ a costly segregation technology to separate conventional and biotech products in the supply chain. The calibrated model is solved for equilibrium prices, quantities, production patterns, trade flows, and welfare changes under different assumptions regarding regional government's production and trade policies, differentiated consumer tastes, and several other demand and supply parameters. Incomplete...

Genetically Modified Grain Corn and Soybeans in Quebec and Ontario in 2000 and 2001
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hategekimana,   Bernard.
This report focuses on the changes in the area of genetically modified (GM) grain corn and soybeans, comparing the year 2001 with 2000. In the 2001 growing season, total GM area increased significantly for both GM grain corn and soybean crops in Quebec and Ontario. The number of large farms seeding GM crops rose considerably, while the number of small- and medium-sized farms growing GM crops was quite unchanged. The increase in GM soybean area was higher than that of GM grain corn. Farms growing both corn and soybeans made the biggest contribution to the increase. The increase appears to be a consequence of both higher average area of GM crops grown per farm by farmers who grew GM crops in 2000 and, to a lesser extent, the adoption of GM technology by new...

Genetically Modified Organisms (GMOs) and Sustainability in Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chern,   Wen S.
Surveys on consumer acceptance of GM foods revealed differences in knowledge, risk perception and acceptance of GM foods in Japan, Norway, Spain, Taiwan and the United States. There were opponents and proponents of GM foods. However, even in the United States, one of the most supportive countries, consumers were willing to pay substantial premiums to avoid GM alternatives. While genetic engineering holds great potential to enhance yield and productivity for many crops, especially those widely cultivated in the developing world, there have been little, if any tangible benefits to the consumer from the first wave of GM crops. Partially due to this lack of consumer benefits, there has been consumer resistance to GM foods in many parts of the world. It would...

Yield correlations between 380 different counties are calculated for non-irrigated wheat.  Using this data, a function is estimated that shows the relationship between correlation and changes in geographic and climate data. In addition movement variables are included added to the specification to capture the impact of moving from one production region to another.  A negative relationship was found between changes in latitude, longitude, precipitation, elevation, and temperature.  Correlations and longitude and precipitation showed downward sloping concave relationship, whereas correlations and latitude showed downward sloping convex relationships.  Changes in latitude and longitude are found to have greatest impact on correlation with elasticities of -1.54...

An adaptive regression model is employed for estimating pre-and post-boll weevil eradication cotton-acreage response.  Results indicate cotton acreage becoming more inelastic to own- and cross-price changes.  As a result of this shift in acreage response and yield increases from eradication, net producer benefits on average are $88.73 per acre.

The coffee roasting segment is passing through deep transformation since the beginning of the 90´s, and the requirement of quality has been essential for the performance of those companies in the market. The quality factor has been playing important role for the competitiveness of the enterprises. Some authors believe that, under the aegis of the market globalization, the quality reaches its highest level of importance in the business decision process and turns out to be the passport for opening the most challenging markets and for upholding the niches in the more competitive markets. However, systems or quality programs generate costs that, usually, are unknown for the firms. In Brazil, the literature on the costs of the quality lacks more comprehensive...

The following Discussion Paper aims to analyse the development path and profitability of grain production in Ukraine, which is one of the most important production branches of most Ukrainian agricultural companies. Methodologically, individual farm analysis and horizontal farm comparison are used. The cost benefit analysis has been widely used for farm analysis of the agricultural sector in market economies. However, only few applications could be observed in agribusiness research in Ukraine in the last years, presumably because of missing or unreliable data. Thus, the goal of this paper is to apply a standard farm management instrument for enterprise analyse in agriculture of a transition country. The results show small differences in production costs...

Giving credit to the microlenders. Formal microlending, credit constraints and adverse selection: a case study of shrimp farmers in Bangladesh
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Andersson,   Camilla I.M.; Holmgren,   Erik; MacGregor,   James; Stage,   Jesper.
Smallholder farmers have long been denied access to formal credit, largely because of the high administrative fees associated with loans. A possible solution to this problem, which has become increasingly popular, is the use of microcredit financing, where innovative means of securing the loans, such as peer monitoring, are used. This paper examines the effectiveness of formal microcredit schemes as compared to the traditional informal credit sources in a rural shrimp farming district of Bangladesh. We compare the two types of credit by studying the technical and allocative efficiencies of the two groups of borrowers. The findings suggest that farmers using both types of microcredit have difficulty accessing credit, often over-utilising labour in order to...

Global welfare effects of transgenic sugar beet
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dillen,   Koen; Demont,   Matty; Tollens,   Eric.
Although the EU is still in a quasi moratorium stage concerning GM crops, doors for GM crops in the sugar industry seem to open. Herbicide tolerant sugar beet could mean a boost for the sugar beet sector. The ex ante impact assessment shows a created welfare of €15 billion during 1996-2014. The rule of thumb found in ex post impact studies of a sharing out between downstream and upstream sector of 2/3 versus 1/3 is seems to be applicable to this case as well. The sugar beet sector and consumers worldwide are the winners while cane growers lose due to technology eroded world prices. The reform of the EU Common market organization for sugar in 2006 seems to create an incentive for innovation to efficient European sugar producers. Crowding out of inefficient...

Autores: Valente,   Airton Saboya Junior.
Fresh fruits became one of the most globalized products within the agricultural sector. Different factors have contributed to propel this trend, such as cost reduction in transportation, improvement in cold chain facilities and changes in dietary habits. Production of fresh fruits for export has grown in Brazil, and it is present in over 30 production hubs. The Brazilian Northeast became one of those focal points, where its fruit production and exports come mainly from irrigated valleys, such as the Petrolina-Juazeiro one. Fruit exports have contributed to transform the Petrolina-Juazeiro valley: they have attracted producers, agribusiness firms, services companies, undergraduate schools, machinery and farm implement manufactures. Besides that, the job...

Globally Flexible Modeling of County-Level Acreage Response for Primary U.S. Field Crops
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cooper,   Joseph C.; Arnade,   Carlos Anthony.
This study takes the standard acreage response model that stems from an expected utility framework, accounting for both price and yield variability, and nests it within a flexible semi-nonparametric (SNP) model consistent with farm-level decision models for computationally tractable results. We use county-level data to estimate the response of farmers’ planting preferences to changes in revenue and other variables.

GM crop technology and trade restraints: economic implications for Australia and New Zealand
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Anderson,   Kym; Jackson,   Lee Ann.
How much might the potential economic benefit from enhanced farm productivity associated with crop biotechnology adoption by Australia and New Zealand (ANZ) be offset by a loss of market access abroad for crops that may contain genetically modified (GM) organisms? This paper uses the Global Trade Analysis Project (GTAP) model to estimate effects of other countries’ GM policies without and with ANZ farmers adopting GM varieties of various grains and oilseeds. The gross economic benefits to ANZ from adopting GM crops under a variety of scenarios could be positive even if the strict controls on imports from GM-adopting countries by the European Union are maintained, but not if North-East Asia also applied such trade restaints. From those gross economic...

GM food technology abroad and its implications for Australia and New Zealand
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Anderson,   Kym; Jackson,   Lee Ann.
The potential economic benefits from agricultural biotechnology adoption by ANZ need to be weighed against any likely loss of market access abroad for crops that may contain genetically modified (GM) organisms. This paper uses the global GTAP model to estimate effects of other countries' GM policies without and with ANZ farmers adopting GM varieties of various grains and oilseeds. The benefits to ANZ from adopting GM crops under a variety of scenarios are positive even in the presence of the ban on imports from GM-adopting countries by the EU (but not if East Asia also applied such a ban).

GM Technology Adoption, Production Risk and On-farm Varietal Diversity
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Krishna,   Vijesh V.; Zilberman,   David; Qaim,   Matin.
This paper examines the impact of transgenic technology adoption on varietal diversity. Transgenic pest-resistant varieties are hypothesized to reduce farmers’ demand for on-farm diversity through an act of substitution, as both serve as production risk reducing instruments. This adverse agro-biodiversity impact might be partially counteracted by an expanding seed sector, supplying a large number of transgenic varieties. The case of Bt cotton in India is taken for empirical illustration. The production function analyses show that both Bt technology and on-farm varietal diversity enhance yield, while reducing the production risk. With few Bt varieties available in the first years, technology adoption entailed a reduction in on-farm varietal diversity. This...

GMOs: Prospects for Increased Crop Productivity in Developing Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Evenson,   Robert E.
Genetically Modified Crops (GMO foods) have been widely available to farmers since 1996. The Gene Revolution, based on recombinant DNA (rDNA) genetic engineering techniques, is seen by proponents as both supplanting Green Revolution varieties, based on conventional plant breeding techniques, and potentially enabling “disadvantaged” production environments, unreached by Green Revolution varieties to achieve productivity improvements. This paper argues that the private firms supplying GM crop products have generally had little interest in selling products in disadvantaged production environments. The paper also argues that present rDNA techniques allow only static gains from specific “trait” improvements. But these GM products can be installed on Green...

Going, Going, Almost Gone: How the Depletion of the Alluvial Aquifer Will Affect Cropping Decisions in the Arkansas Delta
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Popp,   Michael P.; Nalley,   Lawton Lanier; Vickery,   Gina B.
The U.S. Geological Survey (USGS) has determined that agricultural irrigation in Arkansas’ Delta is unsustainable with significant negative economic repercussions on producers net returns affected by the Alluvial aquifer.  This study examines how irrigation restrictions in that region would affect county net returns to crop production.  It also considers the effect of planting less water-intensive bioenergy crops in the event biofuel markets become a reality.   A constrained optimization model determines acreage allocations and net returns under three irrigation scenarios: i) no irrigation restrictions, ii) irrigation restrictions that lead to a sustainable Alluvial aquifer, and iii) irrigation restrictions that would lengthen the life of the Alluvial...

Good Industry-good Investments
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Greer,   Glen; Zwart,   Tony.
New Zealand primary sector industry approaches to industry-good investment, and the approaches to evaluation reported in the literature were reviewed to provide understanding of the key issues in ensuring such investments meet stakeholder needs. The extent to which planning and evaluation processes are linked to achievement of measurable industry objectives varies widely amongst primary sector industries, reflecting differing industry sizes and resource levels. Although these factors inevitably influence investment opportunities and the resources available for planning and monitoring profoundly, a framework has been developed to accommodate these differences, and to be of value to all industries.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dahl,   Bruce L.; Wilson,   William W.
Questions have emerged in the United States and Canada regarding the role and function of quality in international markets.  One has been the definition and composition of different market segments, with a particular focus on higher quality customers.  In this study, trends in U.S. wheat exports are analyzed by class, grade, protein, and market segment.  Analysis shows trends toward increases in exports of higher grades of Hard Amber Durum (HAD) and Hard Red Spring (HRS); whereas, exports of higher quality grades for Hard Red Winter (HRW) appear to be moderate.  Exports of HRS, HRW, and HAD show increases in proportion of exports shipped at higher protein levels and increases in the proportion of exports where protein is specified.  Cluster analysis for...

One of the impacts of higher prices along with greater volatility in futures, basis and spreads is that there is pressure for greater use of cash contracts for grain. There is a wide array of cash contracts with varying terms that pose major strategic alternatives for buyers and the marketing system, particularly as buyers seek to use contracting as an element of risk mitigation. Durum is a crop where many of these issues and challenges are apparent. Durum is more risky than competing crops with greater price, yield and quality risk. And in contrast to competing crops, futures do not exist, cross hedging is poor and forward contracting has been used minimally.

One of the impacts of higher prices along with greater volatility in futures and basis is that there is pressure for an escalation in cash contracting for grain. This volatility has resulted in an unprecedented level of contracting with growers in recent years. There is a wide array of cash contracts with varying terms. There is also a growing realization of growers not delivering on contracts, in part due to escalation in postcontract prices. These are evolving as major strategic issues for buyers and the marketing system, particularly as buyers seek to use such contracting strategies as an element of risk mitigation.

Grain Distribution in Ghana under Imperfectly Competitive Market Conditions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Langyintuo,   Augustine S.
Interspatial and intertemporal grain distribution in Ghana is a private sector activity carried out mainly by traders. These traders sometimes collude to maximize their joint profits. By so doing they influence the conduct of the grains market. To examine the effect of their actions on the informal maize market in Ghana, a spatial equilibrium model was estimated under three scenarios: (1) Perfect competition, (2) Cournot-Narsh conjectures, and (3) Collusion. The results indicate that imperfect competition distorts grain flows, reduces consumer welfare and depresses traders’ sales revenue. Collusive behavior of traders, on the other hand, causes the greatest distortion of grain flows as well as trader and consumer welfare. These results draw attention to...

Grain marketing and National Competition Policy: reform or reaction?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Watson,   Alistair S.
Grain marketing arrangements in Australia have been controversial for many years. Following an account of the historical background to grain marketing, this article concentrates on more recent debates. The most interesting technical economic argument concerns the validity of claims that statutory marketing authorities with export monopoly powers can obtain higher prices. The article also discusses how marketing in Australia has been affected by Commonwealth and State Government policies with respect to microeconomic reform and privatization. Although major changes appear to have been made in grain marketing and its institutions, there are inherent economic problems with the current approach to deregulation.

GRAIN MARKETING POLICY CHANGES AND SPATIAL EFFICIENCY OF MAIZE AND WHEAT MARKETS IN ETHIOPIA

Autores: Negassa,   Asfaw; Myers,   Robert J.; Gabre-Madhin,   Eleni Z.
In the context of on-going market reform in developing countries, there is a need for an improvement in the existing methods of spatial market efficiency analysis in order to better inform the debate toward designing and implementing new grain marketing policies, institutions, and infrastructure that facilitate the emergence of a well developed and competitive grain marketing system. The standard parity bounds model (PBM), while it overcomes many weaknesses of the conventional methods of spatial market efficiency analysis, it does not allow for the test of structural changes in spatial market efficiency as a result of policy changes. In this paper, building on the standard PBM, we develop an extended parity bounds model (EPBM). The EPBM is a stochastic...

Grain Marketing Strategies Within and Across Lifetimes
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Peterson,   Hikaru Hanawa; Tomek,   William G.
To reconcile the discrepancy between the efficient market hypothesis and grain marketing recommendations by advisory services and extension programs, simulated prices from an efficient market are used to compare performance of marketing practices over the long run and in individual 40-year periods. We find that an efficient market can generate diverse price behavior within finite samples, allowing for strategies that are inferior on average to perform relatively better, as frequently as half of the time in an average 40-year lifetime. Lifetime returns of strategies show considerable overlap, suggesting extremely low confidence in recommendations made based on short samples.

As with most sectors of the agriculture economy, the U. S. country grain elevator industry has experienced considerable consolidation and concentration. By the same token, the country elevator's customer base (grain producers and landlords) has also changed rather dramatically as grain production takes place on larger and fewer farms.  The profitability of operating a country elevator is directly related to the volume of grain the country elevator purchases over the course of a marketing year.   Because the basic services offered by country elevators are very similar (purchasing, conditioning and storing grain), country elevators attempt to differentiate themselves from their competition by offering customers a variety of cash grain marketing tools.  These...

Grain price adjustment asymmetry: the case of cowpea in Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Langyintuo,   Augustine S.
Patterns in price adjustment in response to information are important to market practitioners. This study looks at cowpea real wholesale price adjustment patterns in Bolgatanga, Wa, Makola and Techiman markets in Ghana. Using Techiman as the central market, a threshold autoregressive test for asymmetric price adjustment rejected the null hypothesis of symmetric adjustment for only the Bolgatanga-Techiman price series. An autoregressive conditional heteroskedastic regression indicates that wholesalers in Bolgatanga market respond differentially to price signals from Techiman than those in the other two markets. This suggests that policies targeting cowpea traders must recognize the differential responses by wholesalers to information.

GRAIN PRICE STABILITY AND FARMER DECISION MAKING IN CHINA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chen,   Jing; Rozelle,   Scott; Carter,   Colin A.
In this paper we find that real grain prices in China have displayed increased volatility in the past decade. This is true for rice, wheat, corn, and for most of provinces. Farmers in China are found to be risk averse because when they make acreage allocation decisions.  Given the widespread access to land in China, farmers mostly respond negatively in their sown area decisions towards price risk.  The large price variations from 1984-1995 may have contributed to the slowdown in agricultural output growth from 1984-1995.

This paper reports the analysis of two groups of wheat producers: American White Wheat Producers Association members who produce white wheat under contract with the cooperative and those who have chosen not to do so.  The results show the diversity of producers’ attitudes, preferences, knowledge and decision making.  Nonmembers tend to rely more on short-term profitability and are less willing to risk innovation for unproven profits.  Nonmembers also are less supportive of contract production and less inclined to use a young cooperative in that situation.  This study demonstrates that the development of a new coordination mechanism entails much education of participants and that producer involvement also depends on learning on the part of everyone in the...

Over the last three decades, producers in South Dakota have planted increasingly more acres under corn and soybeans and have moved away from producing oats and barley.  The wheat production in the state has also increased during this period. The grain handling industry in South Dakota has also changed over time. The number of commercial elevators has significantly decreased during the past 30 years, and the operating capacities of the remaining ones are much larger. Genetically modified(GM) of transgenic corn and soybeans were introduced in 1996. Presently, South Dakota is leading the  nation in adoption of corn and soybeans.

Grain-supply response in Ethiopia: An error-correction approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Alemu,   Zerihun Gudeta; Oosterhuizen,   K.; van Schalkwyk,   Herman D.
This paper quantifies the responsiveness of producers of teff, wheat, maize and sorghum to incentives using an error-correction model (ECM). It is found that planned supply of these crops is positively affected by own price, negatively by prices of substitute crops and variously by structural breaks related to policy changes and the occurrence of natural calamities. It has found significant long-run price elasticities for all crop types and insignificant short-run price elasticities for all crops but maize. Higher and significant long-run price elasticities as compared to lower and insignificant short-run price elasticities are attributable to various factors, namely structural constraints, the theory of supply and the conviction that farmers respond when...

Autores: Carvalho,   Jose Marcio.
With this article the intention is to add to the Transaction Cost Analysis empirical discussions. It introduces a model that aims to graphically represent transaction arrangements. The proposed model was empirically tested in the Brazilian fruit export sector. Six different fruit were used as the basis for the investigation: melons, grapes, mangoes, papayas, oranges and apples. These are the six most exported fruit produced in Brazil. Two distinct research techniques were used in the investigation: secondary data analysis and interviews. The focal aim of the secondary data research was the characterisation and comparison of the production and export sequences of the six most exported Brazilian fruit types. The content of the semi-structured interview...

In 1993, the Sasakawa/Global 2000 Program (SG) and the Ministry of Agriculture (MOA) began a joint program to demonstrate that substantial productivity increases could be achieved when farmers were given appropriate extension messages and agricultural inputs were delivered on time at reasonable prices. The program provided credit, inputs and extension assistance to participants willing to establish half-hectare demonstration plots on their own land. In 1995, the MOA/SG demonstration program reached more than 3,500 farmers. During the same year MOA launched the New Extension Program (NEP) based on SG principles but managed independently. By 1997, NEP was managing the bulk of the demonstration plots. Although the MOA/SG program is widely considered to be a...

Greenhouse Gas Emission Factor Module: Land Use in Rural New Zealand—Climate Version 1
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hendy,   Joanna; Kerr,   Suzi.
Several different New Zealand economic models produce measures of rural economic activity that have greenhouse gas implications. For climate change analysis, models need to translate economic activity into greenhouse gas emissions. This document estimates functions and creates projections for land-use related greenhouse gas emissions per unit of economic activity that are simple; are based on readily available data and strong science; are consistent with the national inventory in 2002; evolve so that implied net emissions approximately match past inventory totals (1990–2002); and can be linked easily to a variety of models so they can be used in simulations. We estimate dynamic greenhouse gas emission functions for five land uses: dairy, sheep, beef,...

Greenhouse Gas Impacts of Ethanol from Iowa Corn
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Feng,   Hongli; Rubin,   Ofir D.; Babcock,   Bruce A.
As the United States begins to move towards putting an economic value on reducing greenhouse gas (GHG) emissions, the need for improved accounting standards becomes acute. Lifecycle analysis (LCA), which involves the systematic collection and interpretation of material flow in all relevant processes of a product, has become the accepted procedure to use to determine greenhouse gas emissions of products ranging from transportation fuels, to building materials, to food production (Farrell et al., 2006; Hill et al., 2006; Owen, 2004). The basic motivation of LCA is that, to conduct a fair assessment of the environmental impacts of a product, it is necessary to take into account all of the processes throughout the product’s lifespan, including the extraction...

Greenhouse Gas Impacts of Ethanol from Iowa Corn: Life Cycle Analysis versus System-wide Accounting
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Feng,   Hongli; Rubin,   Ofir D.; Babcock,   Bruce A.
Life cycle analysis (LCA) is the standard approach used to evaluate the greenhouse gas (GHG) benefits of biofuels. However, it is increasingly recognized that LCA results do not account for some impacts—including land use changes—that have important implications on GHGs. Thus, an alternative accounting system that goes beyond LCA is needed. In this paper, we contribute to the literature by laying out the basics of a system-wide accounting (SWA) method that takes into account all potential changes in GHGs resulting from biofuel expansion. We applied both LCA and SWA to assess the GHG impacts of ethanol based on Iowa corn.  Growing corn in rotation with soybeans generated 35% less GHG emissions than growing corn after corn. Based on average corn production,...

Greenhouse Gas Mitigation through Energy Crops in the United States with Implications for Asian-Pacific Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schneider,   Uwe A.; McCarl,   Bruce A.
Agriculture-based biofuels have the potential to replace fossil fuels, thereby offsetting greenhouse gas emissions. We estimate emission abatement supply curves from energy crops switchgrass, hybrid poplar, and willow under a wide range of sectorwide greenhouse gas emission reduction incentives in U.S. agriculture. The Agricultural Sector Model employed captures market interactions of biofuel production with traditional agricultural production and with alternative emission mitigation strategies. U.S. results suggest an increasing importance of biomass-based electricity for carbon mitigation incentives above an economic threshold of $50 per ton. At incentive levels of $170 per ton and higher, emission offsets from energy crops provide the highest net...

Greenhouse Tomatoes Change the Dynamics of the North American Fresh Tomato Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cook,   Roberta L.; Calvin,   Linda.
The rapid growth of the North American greenhouse tomato industry has changed the longstanding dynamics of the fresh tomato industry. During the 1990s, Canada emerged as the largest North American producer of greenhouse tomatoes, a prominence it never attained in the fresh field tomato industry. The United States and Mexico have also become important greenhouse tomato producers, consistent with their long dominance in North American fresh field tomato production. Greenhouse tomatoes have changed the look of U.S. retail tomato sales, where they now account for 37 percent of the quantity sold of fresh tomatoes. While the primary U.S. fresh field tomato product, the mature green tomato, long dominated retail sales, its share has decreased significantly due to...

Autores: Gaspar,   P.; Mesias,   F.J.; Escribano Sanchez,   Miguel; Pulido,   F.
The aim of this paper is to model some production variables in extensive livestock farms located in the dehesa ecosystem. We intend to use not only purely economic variables in the construction of the model, but also structural variables in order to identify the characteristics of the farms that have the higher influence. Another objective is to be able to predict these variables at the farm level, using structural variables that are easy to measure. The data used in this work were obtained from a questionnaire survey to the holders/managers of a sample of 69 dehesa farms in Extremadura (SW Spain). The statistical methodology used for the construction of the model was Partial Least Square Regression (PLSR). It can be concluded that the variables relative...

We use a new partial-equilibrium, multi-market international model to analyze trade and agricultural policies affecting markets for peanut/groundnut products. The model covers four goods in thirteen countries/regions, including a large set of developing countries. Welfare is evaluated by looking at consumers' equivalent variation, quasi-profits in farming, quasi-profits in crushing, and taxpayers' revenues and outlays implied by distortions. We calibrate the model on recent historical data and current policy information. We analyze several groundnut trade liberalization scenarios in deviation from the recent historical baseline. Trade liberalization in groundnut markets has a strong South-South dimension, opposing India and, to a lesser extent, China to...

Industrial disposal of effluents on land and the subsequent pollution of groundwater and soil of surrounding farmlands – is a relatively new area of research. The environmental and socioeconomic aspects of industrial effluent irrigation have not been studied as extensively as domestic sewage based irrigation practices, at least for a developing country like India. The disposal of effluents on land has become a regular practice for some industries. Industries located in Mettupalayam Taluk, Tamil Nadu, dispose their effluents on land, and the farmers of the adjacent farmlands have complained that their shallow open wells get polluted and also the salt content of the soil has started building up slowly. This study attempts to capture the environmental and...

Grower perceptions of the impact of protein premiums and discounts for wheat
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Petersen,   Elizabeth H.; Fraser,   Rob W.
This paper presents results of a survey of Western Australian wheat growers designed to elicit perceptions of the impact of protein premiums and discounts for wheat on income, utility and off-farm risk management. The results indicate that a grower’s perception of the scheme’s impact on expected income and utility depends on that grower’s expected protein level. Additionally, growers do not perceive protein premiums and discounts to have affected the variance of income, or their willingness-to-pay for a forward contract. These latter findings are contrary to previous studies of actual rather than perceived effects. However, the perceptions of growers are understandable given that the scheme’s effect on the variance of income is small relative to its effect...

Grower representation and its impact on the governance structure of the Australian Grains Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Farrell,   Terence C.
The Australian wheat industry has changed considerably in structure and governance during the past 15 years. The most important changes have been the deregulation of the domestic market and privitisation of the former Australian Wheat Board into AWB Limited. Through these changes growers have become shareholders in the various companies. Governance of the monopolistic relationship between AWB Limited and AWB International by the Federal Minister of Agriculture and the Grains Council of Australia through the Wheat Export Authority has proved ineffective. Hence a national organisation that represents shareholders is recommended to increase grower governance of the supply chain and marketing of wheat.

Autores: Wilson,   William W.; Dahl,   Bruce L.; Maxwell,   Brett J.
Contract strategies can resolve some of the challenges that exist for property rights conformance of genetically modified (GM) crops. The purpose of this research is to determine how contract terms impact adoption decisions related to GM grain production and marketing. A simulation model was developed for prospective GM introduction in hard red spring (HRS) wheat, and distributions of net returns for growers were analyzed using stochastic dominance and stochastic efficiency. Results illustrate that contracts can be designed to induce desired behavior. Technology fees, probabilities of detection, and the level of non-GM premiums were the most notable factors influencing adoption decisions. In addition, point-of-delivery pricing and premiums for non-GM...

Growth and Equity Effects of Agricultural Marketing Efficiency Gains in India
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Landes,   Maurice R.; Burfisher,   Mary E.
Agriculture is the largest source of employment in India, and food accounts for about half of consumer expenditures. Moving agricultural products from the farm to consumers more efficiently could result in large gains to producers, consumers, and India’s overall economy. This analysis uses a computable general equilibrium model with agricultural commodity detail and households disaggregated by rural, urban, and income class to study the potential impacts of reforms that achieve efficiency gains in agricultural marketing and reduce agricultural input subsidies and import tariffs. More efficient agricultural marketing generates economywide gains in output and wages, raises agricultural producer prices, reduces consumer food prices, and increases private...

GROWTH AND SURVIVAL IN WHEAT FARMING:  THE IMPACT OF LAND EXPANSION AND BORROWING RESTRAINTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Held,   Larry J.; Helmers,   Glenn A.
Simulation is used to examine impacts of land expansion strategies and self-imposed borrowing limits upon growth and survival odds of a dryland wheat farm over a 15-year period.  Compared to share-rent expansion, purchasing land shows only marginally great growth at best, with substantially higher odds of firm failure.  A tradeoff of enhanced survival at the expense of reduced growth results from more conservative borrowing for land.  The marginal value of liquidity (for assisting survival) is relatively high at lower levels of credit reserves.

Harvest-Time Protein Shocks and Price Adjustment in U.S. Wheat Markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Goodwin,   Barry K.; Smith,   Vincent H.
Dynamic relationships among three classes of wheat are investigated using threshold VAR models that incorporate the effects of protein availability. Changes in the stock of protein are found to generate significant responses in the prices of hard red spring wheat and hard red winter wheat, but not soft red wheat. The responses to identical changes in protein stocks are larger when the magnitudes of deviations of protein stocks from normal levels are large. Shocks to the prices of individual classes of wheat result in complex responses in the prices of the other wheat classes. Notably, however, a shock to the price of hard red winter wheat appears to result in little or no response in the price of hard spring wheat, though importantly, the opposite is not...

Agricultural productivity growth has been strong relative to other sectors in the Australian economy, and relative to the agricultural sectors of other developed countries. However, as commonly observed among other developed economies, growth in productivity in the broadacre sector of Australian agriculture seems to have slowed in the past decade. This paper uses the adjusted cumulative sum square (CUSQ) index to examine the trend stability of total factor productivity in Australian broadacre agriculture over the period 1952-53 to 2006-07. The results show that a significant slowdown occurred around the mid-1990s. Further analysis shows that the slowdown in productivity growth is driven by a longterm decline in public R&amp;D investment in addition to poor...

Has Imported Rice Crowded-out Domestic Rice Production in Ghana? What has Been the Role of Policy?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Asuming-Brempong,   Samuel; Osei-Asare,   Yaw Bonsu.
Commercial rice imports have accounted for approximately 61%, food aid in rice accounted for about 2%, and domestic rice accounted for some 37% per annum of rice consumption in Ghana over the four years between 2000 and 2003. Compared to the 1990s, these figures show a gradual decline in the share of local rice production in the total quantities of rice consumed in the country. On the other hand, the proportion of food aid in rice consumed has remained relatively constant over the period, while the proportion of commercial imports has increased steadily. Using the Engel-Granger residual-based co-integration test, a market integration analysis was explored for imported rice and domestic rice which compared a central market for imported rice and five key...

Have Biotech Seeds Increased Maize Yields?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Xu,   Zheng; Hennessy,   David A.; Moschini,   GianCarlo.
Corn yield is determined by soils, weather, seed used and other technology choices. Global population and per capita income growth trends as well as demand from the energy sector have placed great stress on cropland use. Global cropland acres and/or yield per acre will need to increase. Whether new seed technologies have enhanced corn yield is a controversial issue. We study U.S. county corn yields 1964-2008, controlling for location effects, fertilization technologies and weather. We find evidence that trend yield growth has been fastest in the Central Corn Belt, genetic modification technologies have increased trend yield, and this increase has been largest in the Central Corn Belt.

Have coffee reforms and coffee supply chains affected farmers' income? The case of coffee growers in Rwanda
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Murekezi,   Abdoul Karim; Loveridge,   Scott.
Low prices in the international coffee markets have worsened the economic well-being among coffee farmers. In the face of this situation, the Government of Rwanda has introduced coffee sector reforms that aimed to transform the sector in a way that targets the high quality market and moves away from the bulk coffee market. The high quality coffee market has shown consistent growth over time and exhibits price premiums in international market. If these high prices are passed on to farmers who take advantage of the benefits of the new high quality market by selling coffee cherries, access to this new market could help alleviate poverty brought on by low prices in the conventional sector. However, the majority of coffee farmers in Rwanda rely on the...

Have Recent Increases in International Cereal Prices Been Transmitted to Domestic Economies? The Experience in Seven Large Asian Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dawe,   David.
International cereal prices (in US dollar terms) have been increasing since 2003, but it is domestic prices that affect food consumption and production. This paper analyzes, for seven large Asian countries, the extent to which domestic prices have increased since 2003 and presents several conclusions. First, the data show that the increases in world cereal prices have been accompanied by a real depreciation of the US dollar. For many countries (but not all), this depreciation has neutralized a substantial proportion of the increase in world prices. Second, domestic commodity specific policies in several of these Asian countries have further stabilized domestic prices relative to the change in world prices. This has been especially true for rice, the main...

Autores: Bonabana-Wabbi,   Jackline; Taylor,   Daniel B.
Two experimental procedures were employed to value both health and environmental benefits from reducing pesticide use in Uganda.  The first experiment, an incentive compatible auction involved subjects with incomplete information placing bids to avoid consuming potentially contaminated groundnuts/water in a framed field experimental procedure.  Three experimental treatments (information, proxy good, and group treatments) were used. Subjects were endowed with a monetary amount (starting capital) equivalent to half the country’s per capita daily income (in small denominations).  Two hundred and fifty seven respondents were involved in a total of 35 experimental sessions in Kampala and Iganga districts.   The Kampala sample consisted of urban (professional)...

HEALTH TRADEOFFS IN PESTICIDE REGULATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cash,   Sean B.; Sunding,   David L.; Zilberman,   David.
EPA has the authority to ban pesticides to reduce health risks to consumers from food residues. Such bans influence the price of fruits and vegetables, and the resulting consumption shifts impact consumer health. We develop a framework to compare the direct and indirect health effects of pesticide regulation, and investigate the distribution of these effects across social groups. Under some plausible scenarios, the increased incidence of disease from reduced fruit and vegetable consumption outweigh the direct benefits of regulation.  Furthermore, high income consumers receive the greatest direct health benefit from pesticide cancellations, whereas low and medium income consumers are most hurt by the resulting dietary changes.

HEDGING PRICE RISK IN THE PRESENCE OF CROP YIELD AND REVENUE INSURANCE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mahul,   Olivier.
The demand for hedging against price uncertainty in the presence of crop yield and revenue insurance contracts is examined for French wheat farms. The rationale for the use of options in addition to futures is first highlighted through the characterization of the first-best hedging strategy in the expected utility framework. It is then illustrated using numerical simulations. The presence of options is shown to allow the insured producer to adopt a more speculative position on the futures market. Futures are shown to be performing, in terms of willingness to receive. Options are weakly performing when futures markets are unbiased, while they are more performing when futures markets are biased.

HEDGING SPOT CORN: AN EXAMINATION OF THE MINNEAPOLIS GRAIN EXCHANGE'S CASH SETTLED CORN CONTRACT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sanders,   Dwight R.; Greer,   Tracy D.
This research examines the potential basis behavior and hedging effectiveness for the Minneapolis Grain Exchange's (MGE) cash settled corn contract. MGE futures cash settle to the National Corn Index (NCI) calculated by Data Transmission Network (DTN). Focusing on seven regions in Illinois, the data suggest that NCI Futures offer potential advantages over the existing Chicago Board of Trade (CBOT) corn futures. In particular, nearby basis variability could be reduced by nearly one-half from 8.8 cents per bushel to 4.5 cents per bushel, and hedging effectiveness may increase from an average of 80% for the CBOT to 93% for the NCI.

HEDONIC PRICE ESTIMATION FOR COMMODITIES:  AN APPLICATION TO COTTON
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ethridge,   Don E.; Davis,   Bob.
A model of hedonic prices – implicit prices of embodied quality attributes – was developed for cotton lint and the relative importance of various quality attributes were estimated with regression analysis from sample data on observed sales of cotton. Results indicated that producer prices were sensitive to variations in fiber length, micronaire, and trash content. Results also revealed differences in relative importance and sensitivity between years.

Autores: Espinosa,   Juan Andres; Goodwin,   Barry K.
A hedonic price model is applied to a cross-sectional time-series data set of Kansas wheat characteristics. Results indicate that prices received by wheat producers reflect the presence of conventional quality characteristics of wheat and also milling and dough characteristics. Furthermore, the results indicate that the alternative sets of characteristics exhibit quality information that is, to some degree, independent of one another. Important conclusions regarding the efficiency of current grading and pricing practices for wheat are drawn from this analysis.

HEDONIC PRICES IN THE MALTING BARLEY MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   William W.
An important characteristic in the malting barley market is the multitude of quality variables which affect the value of particular samples.  The purpose of this study was to estimate implicit (or hedonic) prices for selected quality factors.  An econometric model was used to analyze factors affecting the variability in malting barley prices, and to estimate implicit prices for plumpness and protein.  The results indicate that a change may be evolving in the price determination process for malting barley.  In particular, the feed grains sector has had increasingly less effect on malting barley prices in recent years.

Autores: Samikwa,   Duncan D.; Brorsen,   B. Wade; Sanders,   Larry D.
Tobacco is notorious for being one of the most difficult commodities to grade.  Here, we determine the implicit prices of various tobacco characteristics using a hedonic price model.  The factors affecting the price received for burley tobacco include reputation of the producer, month of auction and lot size in addition to variables representing quality characteristics.  Many of these characteristics can be controlled by producers through production, harvesting, and curing practices.  The implicit prices should help farmers evaluate whether they should adopt processes to increase quality.  In spite of the large number of factors included, only about half of the price variation across lots could be explained.  Thus, the difficulty of grading tobacco is...

Annual Ryegrass is a significant weed in cereal production in Western Australia. Herbicide resistance is increasing and is a major concern to producers. Long-term, field scale trials are being conducted on a number of sites in the state. The apparent costs and benefits of different management strategies are dependent on seasonal conditions and markets for inputs and products. This paper presents the results of a simulation model of alternative strategies under a wide range of historic conditions. A  conceptual framework for selecting an optimal strategy is explored.

Herbicide-Resistant Technology Price Effects on the Plant Density Decision for Ultra-Narrow-Row Cotton
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Larson,   James A.; Roberts,   Roland K.; Gwathmey,   C. Owen.
Farmers are concerned about the high cost of planting herbicide-resistant cotton with the high plant densities recommended for ultra-narrow-row cotton. This study evaluated the effects on net revenues of four herbicide-resistant technology fee policies used since 1996 by Monsanto, the technology license holder. Results indicate that changes in the technology fee policy by Monsanto have raised the cost of planting herbicide-resistant cotton. As a consequence, farmers may have an incentive to switch from ultra-narrow-row cotton to wide-row cotton and to use a lower plant density when the technology fee is tied to the seeding rate.

HIDDEN HEALTH COSTS OF PESTICIDE USE IN ZIMBABWE'S SMALLHOLDER COTTON
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Maumbe,   Blessing M.; Swinton,   Scott M.
Balancing the numerous benefits that may accrue from pesticide use on cotton, farmers face health hazards. Pesticide-induced acute symptoms significantly increased the cost of illness in a survey of 280 smallholder cotton growers in two districts of Zimbabwe. Cotton growers lost a mean of Z$180 in Sanyati and Z$316 per year in Chipinge on pesticide-related direct and indirect acute health effects. These values are equivalent to 45% and 83% of annual household pesticide expenditures in the two districts. The time spent recuperating from illnesses attributed to pesticides averaged 2 days in Sanyati and 4 days in Chipinge during the 1998/99 growing season.  These pesticide health cost estimates represent lower bounds only; they omit chronic pesticide health...

HISTORY, ORGANIZATION AND STRATEGIES FOR GRAIN PRODUCERS AND THE GRAIN INDUSTRY IN MICHIGAN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Thrush,   Alan J.
The grain system (grain producers and the grain industry) in Michigan finds itself in a transition period. Production (yield) and price limitations along with escalating cost factors have left producers in a situation where, without government assistance, many more would have to exit the farm. The grain industry (in this study, the industry refers to the grain handlers and processors), while in a stronger financial situation than producers, would suffer negatively if volume of grains bought and sold through their facilities decreased, and more in the industry would have to exit.  A transition is needed to increase profitability of grain producers and the grain handlers and processors in Michigan. Without a transition, the trend of decreasing farms and...

HIV/AIDS and Agrarian Livelihoods in Zambia: A Test of the New Variant Famine Hypothesis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mason,   Nicole M.; Chapoto,   Antony; Jayne,   Thomas S.; Myers,   Robert J.
Since the southern African food crisis of 2001/02, the ‘new-variant famine’ (NVF) hypothesis first proposed by de Waal and Whiteside (2003) has become an important part of the conventional wisdom surrounding the relationship between HIV/AIDS and food crises in the region. The NVF hypothesis suggests that HIV/AIDS is eroding agrarian livelihoods and exacerbating the effects of drought and other shocks on agrarian communities. These concepts have begun to shape the HIV/AIDS mitigation and food security policies and programs of governments and development agencies. To date, however, there is a dearth of empirical evidence to support the NVF hypothesis, and there have been no studies specifically designed to tests its predictions.

Hobby Farms and British Columbia'a Agricultural Land Reserve
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Stobbe,   Tracy; Eagle,   Alison J.; van Kooten,   G. Cornelis.
Agricultural land protection near the urban-rural fringe is a goal of many jurisdictions, including British Columbia, Canada, which uses a provincial-wide zoning scheme to prevent subdivisions and non-agricultural uses of the land. Preferential taxes are also used to encourage agricultural use of the land. Small scale hobby farmers are present at the urban fringe near Victoria (the capital), both inside and outside of the Agricultural Land Reserve (ALR). The goal of this paper is to investigate whether hobby farms create problems for agricultural land preservation. We make use of a GIS (geographic information system) model to construct detailed spatial variables and analyse our parcel-level data set using an hedonic pricing model and a limited dependent...

Autores: Urcola,   Hernan A.; Irwin,   Scott H.
This article tests the efficiency of the hog options market and assesses the impact of the 1996 contract redesign on efficiency. We find that the hog options market is efficient, but some options yielded excess returns during the live hogs period but not during the lean hogs period. Our findings indicate that the hog options market is efficient and is consistent with the new contract improving the efficiency of the market. However, other market conditions such as lower transaction costs during the lean hogs period can also contribute to reduce expected option returns during the latter period.

Horizontal coordination and free-riding in a group of certified organic crop growers: An empirical study of the Ezemvelo Farmers’ Organization in KwaZulu-Natal, South Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gadzikwa,   Lawrence; Lyne,   Michael C.; Hendriks,   Sheryl L.
This study investigated the prevalence and determinants of free-riding in the Ezemvelo Farmers’ Organization (EFO), a group of certified organic crop growers in South Africa, using data gathered in a census survey of its 151 partially and fully certified members. The computed free-riding index scores suggested that free-riding posed a serious threat to the group’s collective marketing efforts. Regression analysis showed that members who were male, poorly educated, aware of loopholes in the grading system, and who did not trust the buyer, were more likely to free-ride. In the longer term, the EFO should address institutionalized free-riding by issuing tradable ownership rights. In the short term, it must engage with the packhouse (buyer) to remove flaws in...

Household Level Financial Incentives to Adoption of Conservation Agricultural Technologies in Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Haggblade,   Steven; Tembo,   Gelson; Donovan,   Cynthia.
Although several studies have been conducted to determine the viability of conservation agriculture in Sub-Saharan Africa, almost all such studies are fragmented – often country specific – and with undue emphasis on output effects. However, assessment of the attractiveness of these technologies in Sub-Saharan Africa requires a detailed case-by-case comparison of changes in output and input costs and benefits. This paper reviews a set of responses known collectively as “conservation” or “sustainable” agriculture. Though definitions vary, these technologies typically involve agricultural management practices that prevent degradation of soil and water resources and thereby permit sustainable farm productivity without environmental degradation.

Existing literature suggests the influence of household wealth on farmer's technology adoption decisions. In 2007, this study was conducted to provide a clearer understanding of how differences in household wealth affect the way in which other variables influence adoption decisions. Using data from 369 households in Adama and Adami Tulu Jido Kombolcha districts of Ethiopia, the paper first stratified households into poorly and well-endowed categories based on wealth indices constructed using their productive assets by the principal components method. A double hurdle model was then specified and estimated for each wealth group to assess factors influencing the adoption and use intensity of improved varieties. The results suggest that factors influencing the...

This study conducts a life cycle assessment (LCA) of carbon emissions and estimates the carbon sequestered in 14 commonly sown rice varieties across the Arkansas Delta.  Given the uncertainty regarding future carbon legislation, and increased consumer and industry demand for “greener” products, this study estimates how potential carbon policies would affect rice cultivar selection Hybrid rice varieties, given their higher yield and higher yield per unit of green house gas (GHG) emission, are better positioned to take advantage of any increase in consumer demand for “greener” products and/or absorb any government policy better than conventional rice cultivars.

For 183 crop and county combinations, each distribution is estimated and ranked according to its log-likelihood function observed at out-of-sample observations.  A semiparametric model dominates the contest for most crops and counties, likely due to its flexibility and treatment of heteroskedasticity.  Most other models ranked lower because their variance equation performed poorly out-of-sample.

How can allocative inefficiency reveal risk preference? An empirical investigation on French wheat farms
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blancard,   Stephane; Boussemart,   Jean-Philippe; Crainich,   D.; Leleu,   Herve.
We focus on a simple framework on wheat producer behaviour in a context of price output uncertainty. More precisely, we establish a relationship between ex post output price level and allocative inefficiency that allows to characterize farmers’ risk preferences. Given this analysis, the connection between risk aversion and other socioeconomic variables (such as degree of output specialisation, total asset, debts, farmer’s age…) can furthermore empirically be explored. This relationship is empirically tested on an unbalanced panel including about 650 wheat producers located in the French Department of Meuse over 1992- 2003.

HOW COMPETITIVE IS THE WORLD WHEAT MARKET?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carter,   Colin A.; MacLaren,   Donald; Yilmaz,   Alper.
Japan is one of the largest importers of wheat in the world, with imports originating from three countries, Australia, Canada, and the United States.  Australia, Canada, and Japan all use a government single-desk agency to control wheat trade.  Many previous studies on competition in the world grain trade have argued the market is imperfectly competitive, and they often point to the Japanese market. We study the Japanese wheat import market for this reason, but find no compelling evidence of imperfect competition.

How Far Can Poultry Litter Go? A New Technology for Litter Transport
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carreira,   Rita I.; Young,   Kenneth B.; Goodwin,   Harold L., Jr.; Wailes,   Eric J.
Exporting northwest Arkansas excess turkey and broiler litter to partially fertilize nutrient-deficient cropland in eastern Arkansas can be more cost effective than to supply all crop nutrients with chemical fertilizer only, given current high fertilizer prices.  Cost savings are greater if litter is baled in ultraviolet resistant plastic and transported via truck, since backhaul opportunities reduce truck rates, or alternatively, if raw litter is shipped via a truck-barge combination.  Rice is the crop that allows for greater savings according to a mathematical programming model implemented in General Algebraic Modeling System (GAMS).

How Important is Reputation for New Zealand Wine Makers?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bicknell,   Kathryn; MacDonald,   Ian.
The wine industry in New Zealand has been maturing over the past few decades, with consumers becoming more sophisticated and wineries responding by increasing their production of premium varieties. In addition, there have been several legal changes and subsequent changes to the distribution and marketing of wine in New Zealand that have made wine more widely available. It is therefore an interesting and dynamic time to gain a more comprehensive understanding of the relative effects of regional reputation and producer-specific quality on the willingness to pay for domestically produced premium table wine in New Zealand. Previous empirical work suggests that New Zealand consumers rely on both expert opinion and regional reputation when determining their...

How Market Efficiency and the Theory of Storage Link Corn and Ethanol Markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mallory,   Mindy L.; Hayes,   Dermot J.; Irwin,   Scott H.
In this article we use the theories of market efficiency and supply of storage to develop a conceptual link between the corn and ethanol markets and explore statistical evidence for the link. We propose that a long-run no-profit condition is established in distant futures markets for ethanol, corn, and natural gas and then use the theory of storage to define an inter-temporal equilibrium among these prices. The relationship shows that under certain conditions, future price expectations will influence current spot prices and that a short-term relationship between input and output prices will exist. This short-term relationship will contain fixed costs. We demonstrate validity of the theory using a structural price model and then by means of time-series...

How much can be gained by optimizing nutrient abetment spatially – Cost – efficiency comparison of non – point arable loads from different Finnish watersheds
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Helin,   Janne; Tattari,   Sirkka.
Targeting has become the buzz word in the national agri-environmental policy reform in Finland. It is generally accepted that more environmental benefits could be reaped by implementing environmental protection measures where they have the biggest positive impact. However, considering one of the main environmental problems in Finland resulting from agriculture, eutrophication, the identification of first-best policy or even the biggest contributors among the diffuse nutrient sources remains as a considerable challenge. The model developed in this study aims to demonstrate how the agricultural nutrient load potential can be calculated in a way which supports the identifying of cost-efficient abatement policies. We use metamodeling of dynamic nutrient load...

How Much Do Decoupled Payments Affect Production? An Instrumental Variable Approach with Panel Data
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Weber,   Jeremy G.; Key,   Nigel D.
Agricultural support payments that cause no or minimal production distortions are exempt from World Trade Organization restrictions. If and how much decoupled payments, such as direct payments in the U.S., affect agricultural production remains an open empirical question with implications for policy. We use multiple years of the Census of Agriculture to estimate the aggregate supply response to changes in direct payments. To identify an exogenous source of variation in payments we exploit a provision of the 2002 Farm Act that departed from previous policy by making oilseeds eligible for direct payments, thus increasing payments to areas that historically produced more oilseeds. Using a sample of ZIP codes that accounts for more than eighty percent of the...

How to increase the effectiveness of agri-environmental subsidy schemes through knowledge of farmer perceptions-a choice experiment on pesticide free buffer zones

Autores: Christensen,   Tove; Pedersen,   Anders Branth; Nielsen,   Helle Orstead; Morkbak,   Morten Raun; Hasler,   Berit; Denver,   Sigrid.
Danish farmers have been far less interested in agri-environmental subsidy schemes than anticipated. We use choice experiments to estimate 486 Danish farmers’ preferences for a number of policy relevant scheme-characteristics. Subsidy schemes for pesticide free buffer zones along hedgerows are used as a case and analysed using a random parameter logit framework. By quantifying farmers’ preferences in monetary values, we are able to assess the relative importance of individual scheme-characteristics. Farmer’s assessments of the administrative burden are captured by estimating how they value free-of-charge assistance for the application procedure. To our knowledge, this measure of administrative burden has not been tested before. Our results indicate that...

Hurricanes and Possible Intensity Increases: Effects on and Reactions from U.S. Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chen,   Chi-Chung; McCarl,   Bruce A.
Hurricanes have caused substantial damage in parts of the U.S. Damages are increasing, perhaps as part of a natural cycle or perhaps in part related to global warming. This paper examines the economic damages that hurricanes cause to U.S. agriculture, estimates the increased damage from an increase in hurricane frequency/intensity, and examines the way that sectoral reactions reduce damages. The simulation results show that hurricanes and associated adjustments cause widespread damage and redistribute agricultural welfare. We find that crop mix shifts of vulnerable crops from stricken to nonstricken regions significantly mitigate hurricane damages.

Autores: Azad,   Md Abdus Samad; Mustafi,   B.A.A.; Hossain,   Mahabub.
Hybrid rice, one of the viable and proven technologies has been considered as a new frontier to increase rice production for meeting growing demand for staple food in Bangladesh. Using farm survey data this paper examines comparative profitability of hybrid and inbred rice cultivation and estimates a Stochastic Frontier Function to determine the effect of key variables on farm efficiency. Results show that hybrid rice gives substantially higher yield as well as net return compared to inbred rice which leads to increase and sustainable growth of food grain production. Analysis of Stochastic Frontier model shows hybrid rice farms are technically more efficient than inbred.

Hybrid rice represents a new and increasing popular variety option for rice producers. This study examines the acreage diversification among long grain rice varieties in the southern rice region and presents estimates of thedifferences in expected costs and returns among the production of conventional, Clearfield®, and hybrid rice varieties. Breakeven yield increases required to cover additional hybrid rice production costs are estimated over a range of rough rice market prices for both owner and tenant rental situations. Rough rice market price adjustments resulting from grade differences from milling yields are also discussed.

Vegetable oil production has become one of the fastest expanding cash crop sectors in the last 50 years and it is still increasing rapidly. However the regions of expansion, the sources of plant oil and their importance vary over time. To shed light on this development it is necessary to look at the farm level production systems and their production costs for a variety of countries and oilseeds. In this paper we present the first results of the IFCN Cash Crop Network covering the international comparison of oilseed producing farms. A total of 25 farms with oilseed production have been analysed in compiling this paper. All farms produce at least one of the following oilseeds: soybeans, oilseed rape, sunflower and (two farms) mustard. The farms are located...

Autores: Liu,   Xing.
The goal of this study is to investigate the price relationship of EU biofuel market with other main markets in both horizontal level and vertical level. We first carry out Granger causality between ethanol price of EU, USA and Brazil. Secondly, we use vecto error cointegration Mechnism (VECM) to test the relationship between three selected vegetable oil prices in EU to see the competive potential of EU rapeseed oil compared with imported crude palm oil and soybean oil as the feedstock of biodiesel. Evidence shows that there is a unidirectional Granger causation from both USA and Brazil to EU market. USA price of ethanol is the most influential among the three price series, and EU has the least influence on the contrary. It indicates that it is very...

IMPACT OF A MORE INTENSIVE INSECT PEST INFESTATION LEVEL ON COTTON PRODUCTION: TEXAS HIGH PLAINS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Masud,   Sharif M.; Lacewell,   Ronald D.; Stoll,   John R.; Walker,   J. Knox; Leser,   James F.; Sellar,   Christine.
This study evaluated implications of increased bollworm problems in a 20-county area of the Texas High Plains relative to cotton yields and economic impact. Results did not indicate a serious effect of bollworms upon lint yield when insecticides were used for control. However, estimated annual reduction in farmer profit due to the bollworm for 1979-81 was over $30 million. Yields were estimated to decline about 300,000 bales without insecticide use and about 30,000 bales with insecticide use. This decline suggests potentially serious implications for the comparative economic position of cotton in this region if insecticide resistance were to develop among insect pests.

IMPACT OF ALTERNATIVE FARM PROGRAMS ON DIFFERENT SIZE COTTON FARMS IN THE TEXAS SOUTHERN HIGH PLAINS:  A SIMULATION APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Smith,   Edward G.; Richardson,   James W.; Knutson,   Ronald D.
Eight Texas High Plains cotton farms, ranging in size from 189 acres to 5,570 acres, were simulated under six alternative farm program provisions to determine the likely structural impacts of these programs.  The results indicate mid-size farms benefit more from farm programs than either small or large farms since the programs allow them to remain in business.  Denying mid-size commercial farms access to the farm program would likely accelerate the trend towards a bimodal distribution of farm sizes on the High Plains.

The call for school finance reform has threatened to modify or possibly remove the current property and sales and use tax exemptions currently benefiting Texas cotton producers. This study utilizes a whole farm simulation model to evaluate the economic and financial impact of three alternative sales and/or property tax policy changes on Texas cotton farms along with their respective landowners. Results indicate that removing sales tax exemptions would most adversely impact producers, while removing property tax exemptions has a more negative effect on landowners.

The application of modern biotechnology to plant breeding is considered to be more efficient and quicker than conventional breeding techniques in the development of new and more resilient crop varieties. To test the impact that biotechnology is having on a industrial plant breeding activities, we relate firm level Plant Variety Protection Certificate (PVPC) applications to corresponding expenditure on research and development (R&amp;D), agricultural biotechnology patents applications, field trials of genetically modified crops, firm structure, as well as industry specific characteristics. Regression results indicate agbiotech activities are directly related to PVP applications, hence the creation of new plant varieties.

Impact of Direct Income Payments on Productive Efficiency of Korean Rice Farms
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kang,   Hye-Jung; Kim,   Jeong-Ho.
This paper examines the impact of direct income payments on productive efficiency of Korean rice farms, using farm-level cross sectional data in 2006. For representation of efficiency and its determinants, this paper uses a model that estimates the deviations of farms from a translog distance function and the determinants of these deviations. This paper especially estimates a stochastic frontier production function to explain deviations from best-practice productivity with a two-part error term including statistical noise from measurement error and technical inefficiency arising from farms not reaching the production frontier boundary. The empirical evidence finds that farms that get a higher share of direct payments in farm revenue are less efficient than...

IMPACT OF GLOBAL COTTON MARKETS ON RURAL POVERTY IN BENIN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Minot,   Nicholas; Daniels,   Lisa.
World cotton prices have fallen by about 40 percent over the last two years, focusing attention on the effect of subsidies for cotton growers in depressing prices. This paper combines farm survey data from Benin with assumptions about the decline in farm- level prices to estimate the direct and indirect effects of cotton price reductions on rural income and poverty in Benin. The results indicate that there is a strong link between cotton prices and rural welfare in Benin. A 40 percent reduction in farm-level prices of cotton results in an increase in rural poverty of 8 percentage points in the short-run and 6- 7 percentage points in the long run. Based on the estimated marginal propensity to consume tradable goods, the consumption multiplier is in the...

Autores: You,   Liangzhi; Rosegrant,   Mark W.; Fang,   Cheng; Wood,   Stanley.
Climate change continues to have major impact on crop productivity all over the world. While many researchers have evaluated the possible impact of global warming on crop yields using mainly indirect crop simulation models, there are relatively few direct assessments on the impact of observed climate change on past crop yield and growth. We use a 1979-2000 Chinese crop-specific panel dataset to investigate the climate impact on Chinese wheat yield growth. We find that a 1 percent increase in wheat growing season temperature reduces wheat yields by about 0.3 percent. This negative impact is less severe than those reported in other regions. Rising temperature over the past two decades accounts for a 2.4 percent decline in wheat yields in China while the...

A farm’s physical investment is affected by its fundamental q and by its financial situation, with the later comprising both the firm’s liquidity and its possibility of facing capital market imperfections. This study determines the effects of government payments, depreciation, and inflation on crop farm machinery and equipment investment behavior employing the Nonlinear Generalized Method of Moment (GMM) estimator to estimate the investment system. The magnitude of the lagged cash flows such as government payments, cash crop income, and grain income were largely responsible for determining farm investment behavior in the Kansas agriculture sector. An increase in lagged machinery and equipment depreciation and lagged farm motor vehicle and listed property...

Impact of High Crop Prices on Environmental Quality: A Case of Iowa and the Conservation Reserve Program
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Secchi,   Silvia; Babcock,   Bruce A.
Growing demand for corn due to the expansion of ethanol has increased concerns that environmentally sensitive lands retired from agricultural production into the Conservation Reserve Program (CRP) will be cropped again. Iowa produces more ethanol than any other state in the United States, and it also produces the most corn. Thus, an examination of the impacts of higher crop prices on CRP land in Iowa can give insight into what we might expect nationally in the years ahead if crop prices remain high. We construct CRP land supply curves for various corn prices and then estimate the environmental impacts of cropping CRP land through the Environmental Policy Integrated Climate (EPIC) model. EPIC provides edge-of-field estimates of soil erosion, nutrient loss,...

Stochastic dominance analysis of five crop rotations using twenty-one years of experimental yield data returned results consistent with Pennsylvania cropping practices.  The analysis incorporated yield risk, output price risk, and rotational yield effects.  A rotation of two years corn and three years alfalfa hay dominated for approximately risk neutral and risk averse preferences, as did participation in government programs under the 1990 Farm Bill.  Crop rotation selection appeared to impact net revenues more than the decision to participate in government programs.

IMPACT OF SHELTERBELTS ON GROUNDNUT PRODUCTION IN THERILANDS: A DECOMPOSITION ANALYSIS.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Narayanan,   V. Venkat; Maynard,   Leigh J.
In areas characterized by wind erosion and shifting sand dunes, shelterbelts can increase crop yields. Groundnut yields in southern India increased with the introduction and maturation of shelterbelts.  Decomposition analysis attributed most of the yield increases to the shelterbelts themselves, with a small portion attributed to input use changes.  While shelterbelt cost data are scarce, the estimated value of inputs saved due to shelterbelts suggested a net benefit stream that is initially negative but increasing into the indefinite future.  Public investments in shelterbelts may be the most effective means of preventing land degradation.

Land degradation, in the form of soil erosion and nutrient depletion, threatens food security and the sustainability of agricultural production in many developing countries. Governments and development agencies have invested substantial resources in promoting soil conservation practices, in an effort to improve environmental conditions and reduce poverty. However, very limited rigorous empirical work has examined the economics of adopting soil conservation technology. This paper investigates the impact of stone bunds1 on crop production value per hectare in low and high rainfall areas of the Ethiopian highlands using cross-sectional data from more than 900 households having multiple plots per household.

Autores: Salassi,   Michael E.; Garcia,   Mercedes; Breaux,   Janis B.; No,   Sung Chul.
Conversion to combine harvesters has resulted in Louisiana sugarcane growers delivering a more perishable product to raw sugar factories. Dextran formation increases as the time between harvest and milling is extended. Milling of freshly cut sugarcane reduces the formation of dextran and associated economic losses. One approach available to factories to reduce dextran formation is to extend the harvested sugarcane delivery schedule to the mill. A simulation model was developed to evaluate alternative delivery schedules at raw sugar factories. Economic losses in product value associated with dextran formation were estimated and compared for various extended delivery schedules.

The Uganda government has since 1987 initiated a sequence of tax reforms to address the fiscal challenges facing the country. This paper uses a Computable General Equilibrium (CGE) model to analyze the welfare effects of tax reforms on households and the impact of these challenges on production and firm activities. The findings are consistent with previous studies which found that the introduction of VAT was indeed a progressive policy reform. Zero rating all food items and agricultural products mainly benefit the low income households whose consumption basket is mainly food items. In a quest for further sources of revenue by overtaxing the rich, this could generate further revenues albeit lower savings and investments by this group. Finally, over-reliance...

Impact of the ‘Family-firm life cycle’ on the Management Processes Involved in Sustainable Glasshouse Horticulture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Taragola,   Nicole; Van Lierde,   Dirk; Van Huylenbroeck,   Guido.
In Flanders glasshouse vegetables and ornamental plants are typically produced at family businesses. At this type of businesses the objectives and long-term firm developments are influenced by the so called ‘family-firm life cycle’. In many cases the firm shows a life cycle that corresponds with the life cycle of the entrepreneur. The objective of the paper is to test the hypothesis that the ‘family-firm life cycle’ will have an impact on the personal and business characteristics, objectives and the quality of the management processes involved in sustainable glasshouse horticulture. As sustainable horticulture integrates the three P’s (People, Planet, Profit) special attention is paid to human resource, environmental and financial management. Data for the...

Impact of the New Standard Reinsurance Agreement (SRA) on Multi-Peril Crop Insurance (MPCI) Gain and Loss Probabilities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vergara,   Oscar; Seaquist,   Jack; Zuba,   Gerhard; Harrigan,   Matthew; Lee,   Eric.
We utilize an agricultural model that uses crop/weather relationships at the county resolution and fits robust distributions that take into account the impact that weather has on crop production. Once the crop insurance policy conditions and prices are applied to the modeled county yield distributions, the portfolio gain and losses can be calculated by aggregating the gain and losses at the county level, state level, regional level and nationwide level. Portfolio losses are computed under the old and new SRA rules and regulations for comparison purposes.

Impact of the Sectoral Determination for Farm Workers on the South African Sugar Industry: Case Study of the KwaZulu-Natal North and South Coasts
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Murray,   Justin; van Walbeek,   Corne.
A survey of 103 sugarcane farmers on the KwaZulu-Natal coast was conducted in order to analyse the impact of the Sectoral Determination for Farm Workers (2002) on South African agriculture. The sample was separated into a high wage paying North Coast and lower wage paying South Coast. Typically farmers were unable to distinguish between the impact of the Sectoral Determination and other labour laws. Results indicate that the impact of the legislation is similar in each region. No respondents reported mass retrenchment, but job shedding is disguised by not replacing workers (especially unskilled workers) that leave the farm. A sizeable number of growers (17 per cent on the South Coast and 44 per cent on the North Coast) have reduced the working week to 27...

Impact of Zero Tillage in India's Rice-Wheat Systems
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Laxmi,   Vijay; Erenstein,   Olaf; Gupta,   Raj K.
To date, the most widely adopted resource conserving technology (RCT) in the Indo-Gangetic Plains (IGP)has been zero-tillage (ZT) for wheat after rice, particularly in India. This report reviews and synthesizes the experience with zero tillage in the Indian IGP. Zero tillage of wheat after rice generates significant benefits at the farm level, both in terms of significant yield gains (6–10%, particularly due to timelier planting of wheat) and cost savings (5–10%, particularly tillage savings). These benefits explain the widespread interest of farmers and the rapidity of the diffusion across the Indian IGP, further aided by the wide applicability of this mechanical innovation. The study  subsequently reports on the findings of village-level focus-group...

IMPACTS OF ALTERNATIVE TILLAGE, FERTILIZATION, AND HERBICIDE APPLICATION METHODS ON CORN PRODUCTION COSTS AND RETURNS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Olson,   Kent D.; Weber,   Craig.
The impacts on actual corn production costs and returns were analyzed. Tillage, fertilization, and herbicide alternatives are reported. Both stubble and ridge till planting had lower costs per bushel and higher returns per acre than conventional tillage. Banding of fertilizer and, to a lesser extent, manure management had lower costs per bushel and higher returns per acre than broadcast application of fertilizer. Manure applications increased both diesel fuel use and time required per acre. Since corn yields by herbicide application method varied in the same order as the cash rent cost (a proxy for land quality), the differences between application method may be due to both factors. These observations were from one year and a few farms so should be...

Impacts of an Agricultural Development Program for Poor Coconut Producers in the Philippines: An Approach Using Panel Data and Propensity Score Matching Techniques
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rodriguez,   Divina Gracia P.; Rejesus,   Roderick M.; Aragon,   Corazono T.
Using panel data econometric techniques and propensity score matching procedures, this study evaluates the impact of the MAUNLAD agricultural development program - a program designed to help alleviate poverty in Philippine coconut-producing communities.  Our results indicate that the program had a significant positive mean effect on the recipients' total net farm income.  Moreover, the probability of being in poverty is shown to decrease when a poor coconut producer participates in the program.  The program's emphasis on training, intercropping, and livestock integration, as well as the more participatory approach taken, contributed to the strong positive impact of the program.

There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their...

IMPACTS OF EUROPEAN BIOFUEL POLICIES ON AGRICULTURAL MARKETS AND ENVIRONMENT UNDER CONSIDERATION OF 2ND GENERATION TECHNOLOGIES AND INTERNATIONAL TRADE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Becker,   Arno; Adenauer,   Marcel; Blanco Fonseca,   Maria.
Even though recent discussions on food prices and indirect land use change point at potential conflicts associated with the production of biofuels the appraisal of biofuels as an effective instrument to slow down climate change and reduce energy dependency still prevails. The EU Renewable Energy Directive (EUROPEAN COMMISSION, 2009) underlines this trend by setting a target of 10% share of energy from renewable sources in the transport sector by 2020. As economic competitiveness of biofuel production is still not given in most European countries, support policies are essential to achieve this target. Second generation technologies have still not attained marketability, wherefore biofuel consumption will continue to significantly affect agricultural...

This study investigated the impacts of access to inventory credit, input supply shops, fertilizer microdosing demonstrations, and other factors on farmers’ use of inorganic fertilizer and other inputs in Niger and on crop yields. We found that access to inventory credit and input supply shops has increased the use of inorganic fertilizer and seeds and that microdosing demonstrations have increased the use of inorganic fertilizer. Ownership of traction animals and access to off-farm employment have also contributed to the use of inorganic fertilizer, while larger farms use less fertilizer and labor per hectare. The impacts of these interventions and technologies depend on the crop mix. Inorganic fertilizer has a positive impact on millet and millet–cowpea...

We find that access to warrantage and input shops and participation in fertilizer micro-dosing demonstrations have increased use of inorganic fertilizer. Access to off-farm employment and ownership of traction animals also contribute to use of inorganic fertilizer. Use of organic fertilizer is less affected by these factors, but is substantially affected by the household's crop mix, access to the plot, ownership of durable assets, labor and land endowments, and participation in farmers' associations.

Autores: Acs,   Szvetlana; Hanley,   Nick; Dallimer,   Martin; Robertson,   Philip; Gaston,   Kevin J.; Armsworth,   Paul R.
Hill farming in UK is experiencing very difficult economic circumstances and many farmers rely on subsidies provided by the government for a large fraction of their income. The Peak District National Park is used as a case study to examine how farmers might respond to current policy changes � in particular, the move from area- and headage-based payments to the Single Farm Payment, and how optimal business plans should respond to these changes. The objective of this paper is thus to develop production models that predict how farmers will respond to changing policy framework conditions. For this purpose socio-economic surveys were carried out on 44 sample farms, in order to investigate how the land is managed on hill farms including ongoing policies and...

The effects on marketing margins and Texas what producers of shifting from a period with stable prices to a period without stable prices were investigated using both econometric and simulation techniques.  Empirical evidence reveals wheat export firms are risk averse and that either futures markets were unable to absorb increased price risk or futures markets absorbed increased price risk at a cost of $0.054 per bushel.  Increased variability in prices and reduced farm program benefits substantially reduced the probability of Texas wheat producers receiving a reasonable return on equity and a reasonable rate of asset accumulation.

IMPACTS OF THE ADOPTION OF GENETICALLY ENGINEERED CROPS ON FARM FINANCIAL PERFORMANCE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McBride,   William D.; El-Osta,   Hisham S.
The rapid adoption of genetically engineered (GE) crops by U.S. farmers suggests that these technologies have been perceived to improve farm financial performance.  This study develops and applies an econometric model to data from corn and soybean producers in order to evaluate the financial impacts of the adoption of GE crops.  Results indicate that the adoption of GE crops has had a limited impact on financial performance that varies by crop, type of technology, type of farm, and region of the nation.  Factors other than the financial impacts appear to be important reasons for the rapid adoption of GE crops.

From 1986 to 2007 Egypt’s agricultural policy transitioned from a tightly controlled to a more liberalized regime. This study examines the impact of this change on the performance of the wheat (imported grain) and rice (exported grain) sectors.   In terms of profitability, we found that the cost of production increased substantially in both grains, driven primarily by the rise in land rent and labor wage. But the wheat and rice sectors’ profitability did not suffer significantly, as advances in new seed technologies and adoption of better farm practices including farm mechanization increased yield and compensated for the higher cost.    Considering market efficiency, we found that over the study period the farmer’s share of the consumer’s expenditure...

The paper provides an analysis of the impacts of the biofuel policy on the French arable crop sub-sector. The model used is a biofuel supply model composed of an agricultural module and an industrial biofuel processing module. The agricultural supply model is an aggregation of 1094 farm models, based on data from the French Farm Accountancy Data Network (FADN). Different biofuel chains are included in the model: ethanol from wheat and sugar beet, biodiesel (Vegetable Oil Methyl Ester) from rapeseed and sunflower. Scenarios are built upon the recent policy of an increased demand of biofuels for the next years, under the assumption of fulfilling the targets with domestic production only. Results show that the incorporation target of 7% of biofuels in...

Autores: Dyer,   George A.; Taylor,   J. Edward.
Assessing the human and environmental impacts of biofuels requires unraveling the connection between international trade, on one hand, and local land-use and social change, on the other, while accounting for cross-scalar linkages between and within social and environmental systems. We propose a disaggregated approach to model how macro shocks shape rural households’ decisions, and how these decisions integrate onto aggregate supply and land use patterns. The approach, built on an agent-based model of rural Mexico, is used to explore the impacts of ethanol-driven US corn price increases. Our estimate of a 5.7% expansion in corn area by 2008 and wide variation across regions corresponds fairly well with ex post reports. Estimates from alternative models...

Impacts of Water Supply Changes on the Rice Market of Lao PDR: Stochastic Analysis of Supply and Demand Model
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Furuya,   Jun; Meyer,   Seth D.
Laotian rice producers in upland areas experience highly fluctuating yields and production and producers in wet season rice areas in the southern region face high price risk. This paper examines the exposure to risk of producers in both regions facing changes in water supplies. A supply and demand model of rice in Laos, considering water supply changes, is developed and stochastic elements are added to the model to represent uncertainty in climatic variables. Furthermore, the risks associated with price and production fluctuation are evaluated by using the differences between market and certainty equivalent prices. The results show that the coefficient of variation of production is higher in upland rice than wet and dry season rice, i.e., 0.3226, and if...

Impacts of Weather and Time Horizon Selection on Crop Insurance Ratemaking: A Conditional Distribution Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Woodard,   Joshua D.
An important issue in the agricultural actuarial literature is the extent to which sample period selection affects the accuracy of insurance rating. A conditional Weibull distribution approach is developed which explicitly models the interaction of weather, technology, and other variables on probabilistic yield outcomes to address this issue. Results from an application with an extensive producer-level yield dataset representing commercial-scale Illinois firms suggest that the impact of weather heterogeneity on risk estimation across reasonable samples is likely not as great as is often claimed. The results also suggest that yield risk is decreasing significantly through time, and indicate the presence of trend acceleration. A rating analysis indicates...

Imperfect competition in the fresh tomato industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hadj Djelloul,   Mohammed; Requillart,   Vincent; Simioni,   Michel.
In this paper, we analyse the market power of the retail industry in the French tomato market. Following the methods developed in the New Empirical Industrial Organization, we develop a structural model of this industry. The analysis is based on detailed data on final consumption and prices at both shipper and consumer levels for two types of tomatoes in France. The structural model is composed of a system of demand equation and supply equation. Supply equation includes a term that represents the market power of the retail sector. We use different models of demand in order to test the robustness of our results. We show that i) elasticity of demand varies during the year ii) the retail sector exercise only a "moderate" market power iii) the estimated...

Implications of deregulated wheat market for the Western Cape Province: Evaluation with the aid of a spatial model
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Troskie,   Dirk P.; Vink,   Nick; Wallace,   M.
The deregulation of the single channel marketing system for wheat poses new challenges to producers and advisors in the Western Cape Province. This deregulation is simultaneous with a number of other changes in the socio-political, economic, marketing and technological environments. In facing these challenges it is necessary to incorporate such diverse trends as globalisation and individualisation within a single framework. In the first part of this paper the development of a model, combining spatial data, resource attributes, crop characteristics and financial/economic data in an interactive model is described. This is followed in the second part by the evaluation of the impact of certain macro-economic variables on farm-level enterprises. This is done...

Implications of Integrated Commodity Programs and Crop Insurance
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Coble,   Keith H.; Barnett,   Barry J.
Moving from price-triggered to area revenue–triggered programs was perhaps the most common theme among 2007 farm bill proposals. Area revenue–triggered commodity programs may make farm-level revenue insurance products seem redundant, raising questions about why the federal government should continue both programs. Area revenue–triggered programs would remove much of the systemic risk faced by producers. As a result, private sector insurers may be able to insure the residual risk without federal involvement. This paper examines the effects of moving to area revenue–triggered commodity programs with a focus on public policy issues that would likely arise.

In recent years, plant breeders' rights (PBR) has become a controversial subj ect worldwide. This paper reports the results of a survey of the seed distribution industries in the nine member countries of the International Union for the Protection of New Varieties of Plants (UPOV) as well as the seed trade in the United States (U.S . ) and Canada. The general consensus of the UPOV members was that PBR had resulted in increased private investment in plant breeding and that there had been a shift toward more basic research in the public sector. The findings in the U.S. were similar except that there the changes were perceived to be more crop specific with less funding available for public sector research. In Canada, the major concern centered around the...

Implications of Recent Australian Wheat Industry Developments for Domestic and Overseas Prices
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lobb,   Alexandra E.; Fraser,   Rob W.
This study is motivated by the proposition that the objectives of the AWB Ltd have changed since semi-privatisation of the Australian Wheat Board under the Wheat Marketing Act, 1989. Conceptualising this change of objectives as a shift from revenue maximization to profit maximization, this study examines the impact of such a change on the pricing policies of a multi-market price-setting firm. More specifically, this paper investigates, using two hypothetical objective functions, a risk averse AWB’s price-setting behaviour in an “overseas” and a “domestic” market in response to recent wheat industry developments. In the analysis these developments manifest themselves as differing price elasticities, differing transport costs and uncertain demand functions,...

IMPLICATIONS OF REMOTE SENSING IMAGERY AND CROP ROTATION FOR NITROGEN MANAGEMENT IN SUGAR BEET PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ali,   Mir B.; McBride,   William D.; Daberkow,   Stan G.
Adoption of new technologies, such as remote sensing, is slowed by such factors as high monetary and/or human capital costs and uncertainty about their value.  This analysis explores the impact on nitrogen fertilizer use and efficiency and net returns among sugar beet producers in the Red River Valley from using remote sensing technologies and crop rotation for nitrogen management.  The study found that cropping patterns had a significant impact on nitrogen use and net returns, but that most decision tools used for nitrogen management had little influence.  The impact of using remotely sensed images for nitrogen management in sugar beets was not statistically significant.

IMPLICATIONS OF TEMPERATURE-ACTIVATED POLYMER SEED COATING FOR CROP PRODUCTION IN THE NORTHERN CORN BELT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Archer,   David W.; Gesch,   Russell W.
The value of an innovative new seed technology is evaluated in a discrete stochastic programming framework for a representative farm in the northern Corn Belt.  Temperature-activated polymer coated seed has the potential to increase net returns by reducing yield loss due to delayed planting and by increasing the use of longer season varieties.  A biophysical simulation model was used to estimate the impact of polymer coated seed on corn and soybean yields and on field day availability for five planting periods, two crop varieties and two tillage systems on two different soils under varying weather conditions.  Results show that polymer coated seed increases net returns in corn by $2.50-$3.65 per acre and in soybeans by $4.50-$9.70 per acre.

Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation...

Autores: McLeod,   Ross.
An economic evaluation of three ACIAR projects whose primary objective was to improve postharvest grain drying in Thailand and Australia is provided in this report.  During 1983–1996, ACIAR invested A$1.2 million in research designed to improve grain drying in these countries. Based on current adoption, the investment has resulted in a realised net present value of A$3.6 million. A benefit–cost ratio of 3:1 was estimated for the projects. In other words, for each dollar invested, three dollars of project benefits have resulted. A high proportion of realised benefits was estimated to accrue to Australian rice producers, through reduced grain drying costs, while benefits have also been captured by the Thai rice production industry through reduced postharvest...

The decline in soil fertility in smallholder systems is a major factor inhibiting equitable development in much of sub-Saharan Africa. Some areas fallow in order to strength soil fertility for later planting, but as populations increase, demand follows. and continuous cropping becomes the norm and there is a reduction in yields. This case study summarizes the development of improved tree fallows by researchers and farmers in eastern Zambia to help solve the problem of poor soil fertility. Many farmers are finding that by using improved fallows, they can substitute relatively small amounts of land and labor for cash, which they would need to buy mineral fertilizer. The study has three phases: the historical background (phase 1); an assessment of problems,...

This paper used the Uganda National Household Survey (UNHS) data set of 2005/06 to examine the productivity of improved inputs used by smallholder maize farmers in Uganda. Yield and gross profit functions were estimated with the stochastic frontier model. Results revealed a significant effect improved inputs use on yield but not gross profit. Moreover, farmers who planted recycled seed (of improved variety) without fertilizer obtained lower yield but the highest gross profit. Furthermore, if the opportunity cost of own land and labour inputs in maize production were imputed, overall, farmers made economic losses. Based on the prevailing farmers’ production technology and market conditions, maize cultivation in the range of 2‐3 ha was found to give optimum...

Improved Program Planning Approaches Generates Large Benefits in High Risk Crop Farming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Musshoff,   Oliver; Hirschauer,   Norbert.
This paper examines whether there is room for the improvement of farm program decisions through the incorporation of mathematical optimization in the practical planning process. Probing the potential for improvement, we investigate the cases of four German cash crop farms over the last six years. The formal planning approach includes a systematic time series analysis of farmspecific single gross margins and a stochastic optimization model. In order to avoid solutions that simply exceed the farmer’'s risk tolerance, the apparently accepted variance of the observed program’'s total gross margin which represents an observable reflection of the individual farmer'’s risk attitude is used as an upper bound in the optimization. For each of the 24 planning...

Improved Program Planning Generates Large Benefits in High Risk Crop Farming – A Profitable Application of Time Series Models and Stochastic Optimization
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Musshoff,   Oliver; Hirschauer,   Norbert.
Agricultural production relies to a great extent on biological processes in natural environments. In addition to volatile prices, it is thus heavily exposed to risks caused by the variability of natural conditions such as rainfall, temperature and pests. With a view to the apparently lacking support of risky farm production program decisions through formal planning models, the objective of this paper is to examine whether, and eventually by how much, farmers’ “intuitive” program decisions can be improved through formal statistical analyses and stochastic optimization models. In this performance comparison, we use the results of the formal planning approach that are generated in a quasi ex-ante analysis as a normative benchmark for the empirically observed...

IMPROVED SYSTEMS OF RICE FARMING IN ZAIRE:  A COMPARISON OF UPLAND AND IRRIGATED RICE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kamuanga,   Mulumba.
Cassava, maize, rice, groundnuts and plantains constitute the main food crops in Zaire.  Rice is a staple food in several regions though its consumption has thus been concentrated in the urban centers.  The Department of Agriculture had estimated that rice consumption increased at an annual rate of 2.1 percent for the 1971-74 period and it has also predicted that this rate may reach 9.1 percent by the end of the decade.  One of Zaire's key problems is to meet its domestic demand for rice. The government policy of fixing annual hectarage targets for rice and other crops to be achieved through the opening of new land and through exhorting farmers to grow more rice has not succeeded in closing the gap between supply and demand. The focus now is on development...

With data from 366 smallholders cocoa farmers productivity was shown to be linearly related to and the use of improved cocoa technology in the study area. Both the decision to use improved technologies and the proportion of cocoa land allocated to cocoa production are all significant determinants of increased productivity. In addition, farm level factors characteristics as well as idiosyncrasies are shown to affect productivity. These including age, household size, participation in programs related to cocoa production, access to virgin lands, size of cocoa farm, labour resource use and nativity affect productivity at various...

IMPROVING COMPETITIVENESS OF THE AUSTRALIAN SUGAR INDUSTRY BY ANALYSING CANE SUPPLY ARRANGEMENTS ACROSS THE VALUE CHAIN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brennan,   Lisa E.; Muchow,   Russell C.; Wegener,   Malcolm K.; Higgins,   Andrew J.
The term “value chain” describes the collection of activities that are performed to design, produce, market, deliver and support a product. The Australian sugar industry value chain has a number of distinct stages involved in the transformation of the cane crop into raw and refined sugar and other manufactured products. These stages include production, processing and distribution functions. Despite its linear direction, a critically important feature of the sugar industry value chain is that it is not a collection of independent activities but a system of interdependent activities. In the Australian sugar industry, there remains a significant degree of segregation in the organisation of growing, milling, and marketing activities, despite the fact that...

Improving Irrigated Agriculture: How Far Can We Go?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Meyer,   Wayne S.
The last decade has seen the nexus between increasing world population and the area of irrigated land broken, indicating that further population will need to be fed by improved water productivity rather than through increased irrigated area. But how much improvement is possible? This paper systematically considers irrigated agriculture from the plant through to a catchment, and from production and natural resource use perspectives. While there is some evidence of improvement in transpiration productivity (yield per unit of transpired water) of our common irrigated crops, it seems we have reached the limit of potential improvement. Opportunity still exists to increase economic yield while containing seasonal water use through manipulation of vegetative and...

Improving water productivity: how do we get more crop from every drop?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: International Water Management Institute (IWMI); Comprehensive Assessment of Water Management in Agriculture.
Based on research presented in the book “Water Productivity in Agriculture : Limits and Opportunities for Improvement” by J.W. Kijne, R. Barker and D. Molden. If current trends continue, the water crisis—which is already beginning to rear its head in many countries through depleted groundwater aquifers, dried-up rivers and wetlands, and frequent water shortages—will indeed become a global problem. A recent study by the International Food Policy Research Institute (IFPRI) and the International Water Management Institute (IWMI) projects that if present trends continue, by 2025 competition from growing cities and industry worldwide will limit the amount of water available for irrigation, causing annual global losses of 350 million metric tons of food...

IN SITU CONSERVATION OF CROP GENETIC RESOURCES IN THE MEXICAN MILPA SYSTEM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Van Dusen,   M. Eric.
This dissertation focuses on the theoretical modeling and empirical testing of household motivations for the in situ conservation of crop genetic resources (CGR). An original household survey is used to test whether the household diversity outcomes are different for the cropping system as a whole, for the principal crop, maize, or for the secondary crops, beans and squash.  Agro-ecological characteristics and market characteristics are found to significantly affect the levels of diversity maintained by households.     A review of the economic literature relevant to modeling in situ conservation is presented.  A theoretical model is developed in which a household's decision to plant a milpa variety is linked to household, agro-ecological, and market...

INCENTIVE CONTRACTS TO MEET FUNCTIONAL CHARACTERISTICS IN WHEAT PURCHASING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   William W.; Maxwell,   Brett J.; Dahl,   Bruce L.
Consistency of functional characteristics in hard red spring (HRS) wheat is a concern confronting sellers and buyers.  This research analyzes contract incentives for importers with respect to cost and potential risk of acceptance.  A principal-agent framework is utilized to examine contract incentives.  In the principal-agent contract, the principal offers the contract, the agent rejects or accepts the contract, and then decides how much effort to apply.  All this is subject to risk for the agent and moral hazard for the principal.  An example is presented, for which equilibrium contract terms are a base price of 454 cents per bushel for low quality wheat and a premium of 36 cents per bushel if high quality is achieved.  The premium for high quality is...

Incentive Design for Introducing Genetically Modified Crops
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kingwell,   Ross S.
The introduction of genetically modified (GM) crops raises several issues. This paper looks at incentives required to reduce problems of illegal and improper use of GM proprietary technology used in growing GM crops. A simple model of producer behaviour describes some key influences of a farmer’s response to GM crops. The model is illustrated using the example of INGARD cotton grown in Australia. The key findings are that legitimate adoption of a GM crop by a farmer depends on their attitude to risk, the relative profitability of growing the GM crop, the probability of detection of illegal or improper use of the GM crop and the severity of fines successfully imposed for fraud or contract breaches. In the case of INGARD cotton the problem of illegal and...

Incentive to reduce crop trait durability
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ambec,   Stefan; Langinier,   Corinne; Lemarie,   Stephane.
Inbred line seed producers face competition from their own consumers: farmers who save part of their harvest can costly self-produce. To reduce this competition, seed producers can switch to non-durable hybrid seed production.  In a two-period model, we investigate what is the impact of crop durability on self-production, pricing strategies and switching decision. We first study the pricing decisions and switching decisions of an inbred line seed monopoly. Then, we analyze how the monopoly's behavior is affected by the entry of a hybrid seed producer. We also examine how the introduction of royalties on farmers who self-produce improves efficiency.  Our main finding is that, for some constellation of costs, an inbred line seed monopoly has an incentive to...

Incentives and static and dynamic gains from market reform: rice production in Vietnam
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nhu Che,   Tuong; Kompas,   Tom; Vousden,   Neil.
This article develops a dynamic model to account for the enhanced incentive effects that result from market reform through a move toward private property rights and competitive markets. Reform is captured through an emerging profits function which depends on effective prices and incentives to work harder. Static and dynamic output gains from reform are derived through increases in total factor productivity and induced capital accumulation. The model is applied to rice production in Vietnam over the period 1976–94. The more extensive is market reform, the larger the effects found on rice output, the capital stock and transitional growth rates, suggesting that incentives and more competitive markets matter greatly.

Incentives for Fertilizer Use in Sub-Saharan Africa: A Review of Empirical Evidence on Fertilizer Response and Profitability
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Yanggen,   David; Kelly,   Valerie A.; Reardon,   Thomas; Naseem,   Anwar.
This research addresses two questions: Why is fertilizer not yet fulfilling its potential as a major stimulus to agricultural productivity in SSA? What can be done to improve the situation? Our answers are based on an extensive review of fertilizer response, profitability, and policy literature as well as some analysis of crop budgets and aggregate national statistics on fertilizer consumption. Much of the debate about fertilizer use in SSA focuses on two issues: whether the profit incentive is adequate and, if so, whether farmers have the capacity to access and use it.

Soil erosion and environmental degradation are serious problems facing food security in Haiti. In 1999, the annual soil loss due to erosion was estimated at 36 million m3 tons. The government of Haiti has been aware of these deteriorating conditions and has sought international assistance to reduce these problems. In 1993, the United States Agency for International Development implemented a soil conservation project and millions of dollars were spent on the encouragement of adoption of soil conservation measures; yet the problems of soil degradation is still menacing food security in Haiti. Hence the need to evaluate the impact of soil conservation in Haiti is important. A survey of 951 farmers, who adopted soil conservation techniques in Haiti, was...

INCOME TAX REFORM AND CALIFORNIA ORCHARD DEVELOPMENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carman,   Hoy F.
The effects of requiring capitalization of citrus and almond orchard development expenses on acreage, production and product prices for seven California orchard and vine crops are estimated.  Acreage and production of citrus and almonds decreased, as expected.  The decreases in orange and lemon acreage, however, were more than offset by increased acreage of walnuts and grapes.  The switch of developer and investor interest to walnuts and grapes appears to have added to the cyclical instability of production and prices for these two crops.  Perennial crop adjustments to selective changes in tax provisions involve very significant time lags.

INCORPORATING BIOFUELS INTO A PARTIAL EQUILIBRIUM MODEL OF THE EU AGRICULTURAL SECTOR
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Binfield,   Julian C.R.; Westhoff,   Patrick C.; Le Cadre,   Elodie.
The impact of increased consumption of biofuels on agricultural markets has already been substantial, and will increase further as countries around the world seek to expand the proportion of their energy that they get from renewable sources. Models of the agricultural sector must therefore include some consideration of the demand for agricultural products for biofuels and the byproducts that are produced as part of the production process that are returned to the agricultural sector. In this paper the method of introducing biofuels into the FAPRI GOLD (grains, oilseeds, livestock and dairy) model is discussed. A scenario is run whereby the EU is assumed to introduce a binding 10% target by 2020 and the results are discussed in order to illustrate the...

Incorporating Collateral Information Using an Adaptive Management Framework for the Regulation of Transgenic Crops
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Linacre,   Nicholas A.; Burgman,   Mark A.; Ades,   Peter K.; Stewart-Oaten,   Allen.
A lack of data often makes biological management decisions difficult and has been an area of contention in the debate over the approval of transgenic crops. Our knowledge of natural systems is limited and our ability to gain additional information, quickly and effectively, is often handicapped by statistical complexity. To adequately cope with this requires new approaches and models that integrate decision-making and management. This paper describes one possible approach to the integration of decision-making and management, which may have application for the regulatory approval of transgenic crops. In many situations countries wishing to approve transgenic crops will have limited data on the environmental performance of the crop. The approach outlined in...

Pollution of the environment by metals and organic contaminants is an intractable global problem, with cleanup costs running into billions of dollars using current engineering technologies. The availability of alternative, cheap and effective technologies would significantly improve the prospects of cleaning-up metal contaminated sites. Phytoremediation has been proposed as an economical and ‘green’ method of exploiting plants to extract or degrade the contaminants in the soil. To date, the majority of phytoremediation efforts have been directed at leaping the biological, biochemical and agronomic hurdles to deliver a working technology, with scant attention to the economic outlook other than simple estimates of the cost advantages of phytoremediation over...

INCORPORATING THE 1990 FARM BILL INTO FARM-LEVEL DECISION MODELS: AN APPLICATION TO COTTON FARMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Duffy,   Patricia A.; Cain,   Danny L.; Young,   George J.
A five-year, 0.1, mixed integer programming model was developed to analyze the effects of 1990 Farm Bill legislation on the crop-mix decisions made on cotton farms.  Results showed that, when compared to the 1985 Farm Bill, the 1990 Farm Bill can result in higher whole-farm income despite new "triple base" provisions limiting payment acres.  The increase in income results from elimination of limited cross-compliance provisions and the change to a three-year base calculation.  The model was also used to assess the likely impact of possible changes in the current legislation.

INCORPORATION OF WITHIN-SEASON YIELD GROWTH INTO A MATHEMATICAL PROGRAMMING SUGARCANE HARVEST SCHEDULING MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Salassi,   Michael E.; Champagne,   Lonnie P.; Legendre,   Benjamin L.
This study focuses on the development of a optimal harvest scheduling mathematical programming model which incorporates within-season changes in perennial crop yields.  Daily crop yield prediction models are estimated econometrically for major commercially grown sugarcane cultivars.  This information is incorporated into a farm-level harvest scheduling linear programming model.  The harvest scheduling model solves for an optimal daily harvest schedule which maximizes whole farm net returns above harvesting costs.  Model results are compared for a commercial sugarcane farm in Louisiana.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rafsnider,   Giles T.; Skold,   Melvin D.; Driscoll,   Richard S.
The U.S. Congress and courts have directed federal natural resource agencies to use better information for management decisions than they have used in the past.  It is also important for these agencies to improve the efficiency of resource use where possible.  This information economics study estimates increased costs and revenues which can be directly imputed to improving the accuracy of range forage production surveys.  It suggests that a high level of survey accuracy may often be justifiable.

1. Changes in spinning technology have increased the premium on high quality lint in the world market and increased the discount for lint contaminated with non-vegetative matter 2. The inherent characteristics of most African lint, plus the fact that it is hand-picked, should give it a substantial premium in the world market. However, because so much African lint is highly contaminated by world standards, much of it trades at a discount to Index A. 3. Zambia has been the outstanding success among a sample of nine SSA countries in improving quality; this achievement is directly attributable to the efforts of Dunavant and Cargill, made possible by company culture and by the concentrated structure of Zambia's industry 4.

This study evaluates the potential impact of the recent world food prices on the Ugandan economy and possible policy options to respond to it. Uganda is largely a net exporter of some cereals whose prices increasing considerably especially maize. Using a recursive dynamic CGE model, we attempt to answer questions on who are the beneficiaries and losers after the surge in food prices. The rural producers of maize tend to benefit considerably with their poverty levels reducing. On the other hand, the urban purchasers of cereals are affected owing to the higher prices of food. this therefore suggests that the Ugandan government should take advantage of the increasing food prices by stimulating and undertaking policies that would enhance productivity...

Developments in the Indian seed industry and their impact on access and use of commercial seed by farmers have been examined. Various types of seed systems such as hybrids, self-pollinated crops, vegetatively propagated crops, crops with high seed volume, etc have been analysed. It has been shown that the commercial seed markets for hybrids are well developed, but these need improving flow of information to farmers and effective regulation of unscrupulous traders, etc. There are significant changes in terms of seed regulations, management of GM crops and protection of intellectual property. Since all these regulations are mutually enforcing, there is a need for developing institutional capacity for their enforcement, as well as flexibility to learn from...

Indian Wheat and Rice Sector Policies and the Implications of Reform
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Landes,   Maurice R.; Jha,   Shikha; Srinivasan,   P.V.
During 1998-2002, India experienced record public surpluses of wheat and rice, sharply higher government grain subsidy outlays, and declining per capita consumption of wheat and rice. By 2006, despite continued high subsidies and sluggish domestic consumption, India developed a large wheat deficit because of reduced price incentives, weak yield growth, and rising subsidized consumption. The pronounced market cycles and declining per capita consumption for India’s major food staples are creating pressure for Indian policymakers to adjust longstanding policies. While there has been no political consensus on more fundamental reform, recent policy changes have moved toward better targeting of food subsidies to low-income consumers, decentralization of...

Autores: Ramanna,   Anitha.
The demand for extending intellectual property protection to agriculture in developing countries has met with counterclaims for granting farmers' rights. Developing countries are currently attempting to fulfill these demands by evolving new IPR regimes that simultaneously protect the rights of breeders and farmers. What are the possible implications of establishing such a system of multiple rights on the utilization and exchange of genetic resources among various actors? Could the attempt to distribute ownership rights to various stakeholders pose the threat of an "anticommons", where resources are underutilized due to multiple ownership? The answers to these questions have important implications for the future of agricultural growth in developing...

With a rapidly expanding economy many changes are taking place in India today. The business-as-usual (BAU) scenario, which assumes the continuation of current trends of key water demand drivers, will meet the future food demand. However, it leads to a severe regional water crisis by 2050, where many river basins will reach closure, will be physically water-scarce and will have regions with severely overexploited groundwater resources. While the alternative scenarios of water demand show both optimistic and pessimistic water futures, the scenario with additional productivity growth is the most optimistic, with significant scope for reducing future water demand.

ÍNDICE TECNOLÓGICO E SAZONALIDADE DO MARACUJÁ NO EXTREMO SUL DA BAHIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Araujo,   Antonio Carlos; Khan,   Ahmad Saeed; Silva,   Lucia Maria Ramos; Araujo,   Leonardo Ventura.
A cultura do maracujá está em fase de crescimento no Extremo Sul da Bahia, o que contribuiu para que o Estado da Bahia tenha alcançado a posição de maior produtor dessa fruteira. Esta alavancagem do maracujá na região se deve às condições edafo-climáticas favoráveis e à necessidade de diversificar a economia em virtude da crise da cacauicultura. A sustentabilidade da cultura do maracujá depende das tecnologias e informações que possam ser disponibilizados aos produtores e que sejam gerados na própria região, a exemplo da análise do índice tecnológico da cultura e da sazonalidade dos preços, os quais são os objetos do presente trabalho. O estudo ficou concentrado nos municípios de Alcobaça, Prado e Teixeira de Freitas por serem os maiores produtores da...

Industry Organization and Output Size Distribution of Cotton Gins in the U.S.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mutuc,   Maria Erlinda M.; Hudson,   Darren.
With cotton output declining by 46 percent from 2005-2008 (from 23.89 M bales in 2005 to 12.8 M bales in 2008), gins are processing less cotton.  This paper examines how output size distribution of cotton gins in the U.S. has evolved and the extent to which the developments in the U.S. ethanol industry, specifically the passage of the Energy Policy Act in 2005 (and its subsequent revisions), have influenced this structural process.  Markov transitional probability matrices (TPMs) are estimated for two periods: 1994-2004 and 2005-2008 to determine changes in output size distribution of gins.  TPMs indicate that relative to the pre-2005 period, gins had a greater propensity to process lower outputs after 2005. It is purported that in industries constrained...

INFLUENCE OF QUALITY AND SCARCITY OF INPUTS ON THE ADOPTION OF MODERN IRRIGATION TECHNOLOGIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dinar,   Ariel; Yaron,   Dan.
This article describes the influence of input quality and scarcity, environmental conditions, human capital, water price, and other variables on adoption rates for modern irrigation technologies in terms of both speed and extent of application. An empirical model is developed to apply these relationships to citrus groves in Israel. Results show that modern irrigation technologies tend to be adopted sooner and to a greater extent (a) on groves located on relatively low quality land, (b) in regions with higher evaporation rates, (c) on groves planted with more sensitive rootstock, and (d) on groves grown under conditions of restricted water allotments and higher water prices. Management, human capital, and scale of operation also affect the level and speed...

Autores: Djuric,   Ivan; Goetz,   Linde; Glauben,   Thomas.
This paper analyzes how the market interventions of the Serbian government during the food crisis 2007/2008, inter alia a de facto export ban, have affected domestic wheat markets. Besides a comprehensive description of the crisis policy and its effects on the Serbian wheat market, we investigate how it influences the equilibrium and stability of the Serbian wheat market and its integration with the world market within a price transmission model. Applying a Markov-switching error correction model to weekly wheat grower prices in Serbia and world market prices, two states of the wheat market are identified. Our results suggest that although the long-run price elasticity did not change during the crisis, the market equilibrium was disrupted and the market...

INFORMATION QUALITY, TECHNOLOGY DEPRECIATION, AND BT COTTON ADOPTION IN THE SOUTHEAST
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marra,   Michele C.; Hubbell,   Bryan J.; Carlson,   Gerald A.
In 1996, Bt cotton became one of the first genetically engineered crops to be available commercially.  This study focuses on the various sources and quality of information about Bt cotton profitability available to farmers in the Southeast and assesses the relative importance of such information in the farmers' adoption decisions.  A model of the individual decision to adopt is developed to incorporate two recent theories  of the role of information quality (the "effective information" hypothesis and the "popularity" hypothesis) as well as the effect of current technology depreciation.  The data show some support for all three factors as determinants of adoption.

Use of the economic threshold to improve the efficiency of preemergent-herbicide treatment decisions is limited by a lack of weed information.  An economic model for assessing the expected value of weed information needed to implement a threshold decision rule is developed.  Empirical results suggest that early season weed information can have value in cabbage weed management in Massachusetts.

Innovation and Enterprise in Wheat Farming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parish,   Ross M.
This article is concerned with certain aspects of the entrepreneurial behaviour of wheat farmers - in particular, with their adoption of new techniques and means of production. The study is based on data secured in the course of a field investigation carried out late in 1953, in which forty-eight wheat farmers, residing in a particular locality in northern New South Wales, were interviewed.  The primary aim of the investigation was not to estimate the extent to which particular technological innovations are being adopted throughout the wheat belt, or in any particular part of it. Its aim was, rather, to gain some idea of the factors which influence farmers in either adopting or not adopting a particular innovation, or innovations in general. In other...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mekonnen,   Dawit Kelemework; Spielman,   David J.; Fonsah,   Esendugue Greg.
The paper uses a stochastic frontier analysis of production functions to estimate the level of technical efficiency in agriculture for a panel of 29 developing countries in Africa and Asia between 1994 and 2000. In addition, the paper examines how different components of an agricultural innovation system interact to determine the estimated technical inefficiencies. Results show that the mean level of technical efficiency among the sampled countries was about 86 percent, with some modest increases during the period in question. These results suggest that there is room for significant increases of production through reallocations of existing resources. Despite significant variation among countries, these results also indicate quite a number of least...

Innovative capacity and productivity: an empirical analysis of Australian grain growers
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nossal,   Katarina.
Slowing productivity growth in the Australian grains industry has led to calls for increasing investment in rural R&amp;D to advance agricultural technology. However, recent research also suggests there is strong potential to increase productivity by enhancing uptake of existing innovations. The productivity gains from innovation adoption are likely to depend on the capacity of farmers to effectively select, adapt and integrate innovations into existing farming systems. In this paper, the innovative capacity of grain growers is characterised by variables related to the farm, the farmer and their operating environment. The influence of these factors on on-­‐farm innovation adoption is tested using an ordered probit model. The relationship between innovative...

1. Smallholder farmers in Africa require reliable access to purchased production inputs and credit to take advantage of export opportunities from production of cotton. 2. Unregulated and poorly coordinated markets for cotton, production inputs and credit have too often failed to deliver sustainable production finance to farmers for cotton production resulting in a variety of different approaches to these problems among African countries. 3. Among the countries studied, approaches have varied from State monopolies to private markets with several large firms managing to achieve temporary duopolies. 4. Zambia has been relatively successful in dealing with the input-credit needs of cotton farmers for periods of time but the system has been unsustainable,...

Autores: Boland,   Michael A.; Marsh,   Thomas L.
Using 23 years of data (1978-2000), this study examines seven vertically integrated sugar beet plants representing three different companies in the United States. The objective of this research is to identify the marginal costs of producing sugar beets for vertically integrated sugar beet processors as a way of determining the cost savings from higher quality sugar beets. In doing so, we account for quality differences in the sugar beet input that are used to manufacture the refined sugar output. The results quantify links between high quality sugar beets and lower processing costs.

One of the Government of Rwanda’s key post-war policy objectives has been to increase agricultural productivity and ensure food security by promoting a transition from semi-subsistence production and marketing practices to intensive production and highly commercialized agricultural markets. The government wants farmers to increase land and labor productivity through the use of modern inputs, thereby generating substantial surpluses which can be sold to pay for inputs and generate increases in farm incomes.

Autores: Ghelfi,   Rino; Bertazzoli,   Aldo; Marchi,   Alan; Rivaroli,   Sergio; Samoggia,   Antonella.
In order to measure agriculture sustainability, the efficient use of inputs becomes a crucial issue. In this perspective, the analysts concentrate their attention on the total factor productivity index (TFP). In this view, Lynam and Herdt (1989) proposed the TFP as a suitable assessment of the sustainability of single crops, of cropping systems or of farming systems. Even if the TFP does not take into account the non-market output (social and environmental aspects), it is possible to argue that a negative trend of TFP represents a resources’ degradation if related to the generated outputs. On the other hand, the non-negative trend of TFP represents a fitting measure of a sustainable agricultural system and of an efficient use of the resources. The aim of...

Tomato, cabbage and garden egg (African eggplant, or Solanum Aethiopicum) are important crops for small-scale farmers and migrants in the rural and peri-urban areas of Ghana. Genetic modification (GM) has the potential to alleviate poverty through combating yield losses from pests and diseases in these crops, while reducing health risks from application of hazardous chemicals. This ex-ante study uses farm survey data to gauge the potential for adoption of genetically-engineered varieties, estimate the potential impact of adoption on farm profits, and highlight economic differences among the three crops. Farmer's expenditures on insecticides are below the economic optimum in all three crops, and the estimated function for damage abatement shows that...

A new CEA (Controlled Environment Agriculture) system growing Boston lettuce, Lactuca Sativa cv. ‘Vivaldi’, achieves the same quality and quantity of production every day of the year. The year-round constant quantity and quality production indicate potential for success. However, our research showed that out of nine selected U.S. locations with different climatic and economic conditions, the Northeast had 25.7 percent higher production costs for the same yield. The analysis indicated that given current prices and costs, CEA hydroponic lettuce production in northern climates such as Ithaca in upstate New York and Chicago is marginal to negative in terms of economic viability. As a result, the question arises about the future viability of CEA in areas such...

This study records the use of hybrid maize seed and fertilizer by small-scale farmers in Malawi, as well as their opinions about these inputs, from 1989-90 through 1996-97. Its main purpose is to determine whether the principal constraint to smallholders’ use of maize hybrids is the acceptability of the hybrid maize germplasm or the institutional reforms and policies affecting its use. The study also provides information about a practice that has implications for the impact of seed technologies and seed industries — the recycling of nonconventional hybrids (i.e., saving seed of an F1 hybrid to plant in subsequent seasons). Findings of the most recent farmer survey in 1996-97 demonstrate that the grain quality or yield characteristics of maize hybrids no...

Although many irrigation systems in the dry zone of Sri Lanka have water shortage problems, water consumption is very high during land preparation. This paper analyzes the impact of institutional interventions on efficient water management, especially during the land preparation period. It provides a comprehensive understanding of the factors behind prolonged periods of land preparation so that system managers and farmers communities can develop appropriate interventions to reduce water consumption.

Institutional design principles for accountability in large irrigation systems.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Merrey,   Douglas J.
Argues that single irrigation systems managed by autonomous system-specific organizations accountable to their customers, perform better and are more sustainable than those managed by agencies dependent on the government, or by agencies responsible for multiple systems. Selected cases are reviewed and the plausibility of this hypothesis established. General recommendations are made for policy makers designing irrigation reform programs.

Institutional Options for Sustainable Irrigation: An Evidence from Bulgaria
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Penov,   Ivan.
This paper investigates a local problem of common pool resources (CPR), the solution of which needs a balance between the collective and private interests. In the political context we have a large group of actors with a short planning horizon and a lack of trust among them. CPR provision is organised in a centralised way. The state enforcement mechanism is weak and cannot protect the individuals or eventually back the collective decisions. The above problem is investigated in the case of irrigation in Bulgaria where water usage declined by nearly 85% during the period of transition. In addition, large parts of the existing canal systems were abandoned. Three groups of institutional options are investigated in the paper: improvement of the local level...

INSURING AGAINST LOSSES FROM TRANSGENIC CONTAMINATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ripplinger,   David G.; Hayes,   Dermot J.; Lamkey,   Kendall R.
Concerns about contamination of the food supply and the financial losses that would result have limited the promise of certain genetically engineered plants. This article addresses the situation by constructing an insurance pricing model to protect against those losses.  The model first estimates the physical dispersal of corn pollen subject to a number of parameters.  This physical distribution is then used to calculate the premium for fair valued insurance that would be necessary to destroy contaminated fields.  The flexible framework can be readily adapted to other crops, management practices, and regions.

The CLUES model is an integrated catchment based model that designed to assist policy makers in understanding the implications of land use scenarios for water quality and a range of other indicators. CLUES integrates a number of existing models from several research providers, including SPARROW (catchment hydrology), OVERSEER and SPASMO (nutrient losses), ENSUS (nitrate leaching risk), and a socioeconomic model. These are combined in a GIS framework which allows scenarios of land use to be assessed in a spatial manner. Regional council staff have been trained in its use, and the model is under ongoing development in response to feedback from users. This paper discusses the overall framework of the CLUES model, and discusses in greater depth the...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kirby,   Mac; Mainuddin,   Mohammed; Gao,   Lei; Connor,   Jeffery D.; Ahmad,   Mobin-ud-Din.
We aim to model the impact of variability in and changes to water availability in the Murray-Darling Basin on flows available to the environment and irrigation, and impact on the value of irrigated agricultural production. Our objective is to understand the opportunities for changed management of the basin, how they are constrained by climate change and other factors, and how they might affect the returns to irrigation and flows for the environment, so that we may provide information to help plan for the future. In this paper we describe the model: in other papers in this conference we describe analyses of water availability and use in the basin based on this model. The hydrology component of the model is based on a simple, monthly water balance stocks and...

Integrated land use modelling of agri-environmental measures to maintain biodiversity at landscape level
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schonhart,   Martin; Schauppenlehner,   Thomas; Schmid,   Erwin.
Integrated land use models (ILM) are increasingly applied tools for the joint assessment of complex economic-environmental farming system interactions. We present an ILM that consists of the crop rotation model CropRota, the bio-physical process model EPIC, and the farm optimization model FAMOS[space]. The ILM is applied to analyze agri-environmental measures to maintain biodiversity in an Austrian landscape. We jointly consider the biodiversity effects of land use intensity (i.e. nitrogen application rates and mowing frequencies) and landscape development (e.g. provision of landscape elements) using a rich indicator set and region specific species-area relationships. The cost-effectiveness of agri-environmental measures in attaining alternative...

Integration and Equilibrium in the Maize Markets in Southern Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mutambatsere,   Emelly; Mabaya,   Edward T.; Christy,   Ralph D.
For most countries in southern Africa, food security has been addressed through self-sufficiency, traditionally attained through widespread government involvement in the input and output markets for major food commodities.  Food policies through the 1980’s have been characterized by input subsidies for farmers; fixed, pan-seasonal and pan-territorial farm level pricing systems, mainly implemented through parastatal marketing boards; as well as subsidies and price controls at the wholesale and retail levels.  Under Structural Adjustment Programs of the 1990’s, most of those policies were abandoned for more market oriented policies.  During the same period, many countries in the region joined the multilateral trading system, and on a regional level, two...

Intellectual Property Rights and Crop-Improving R&amp;D under Adaptive Destruction
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Yerokhin,   Oleg; Moschini,   GianCarlo.
This paper studies how the strength of intellectual property rights (IPRs) affects investments in biological innovations when the value of an innovation is stochastically reduced to zero because of the evolution of pest resistance. We frame the problem as a research and development (R&amp;D) investment game in a duopoly model of sequential innovation. We characterize the incentives to invest in R&amp;D under two competing IPR regimes, which differ in their treatment of the follow-on innovations that become necessary because of pest adaptation. Depending on the magnitude of the R&amp;D cost, ex ante firms might prefer an intellectual property regime with or without a "research exemption" provision. The study of the welfare function that also accounts for...
