A comparative efficiency analysis of wheat farms using parametric and nonparametric methods
Provedor de dados: 31
Autores: Mo,   Lijia.
This study examined whether the efficiency measures were invariant to choice of parametric and nonparametric methods for a sample of 183 wheat farms. The efficiency measures from the deterministic parametric method were smaller than those from the deterministic method. There was a trade-off between scale efficiency and economic efficiency. In the deterministic nonparametric method, the economic efficiency, scale efficiency and overall efficiency results were invariant to the number of inputs or the dimensionality. Only allocative and pure technical efficiency measures depended on the dimensionality. This work illustrated the importance of holding curvature for the cost function in stochastic frontier results.

Wheat / Flour Price Transmission and Agricultural Policies in Ukraine: A Markov-Switching Vector Error Correction Approach
Provedor de dados: 31
Autores: Brümmer,   Bernhard; Zorya,   Sergiy.
The analysis of price transmission between raw and processed agricultural products in transition countries is complicated by the frequently changing conditions on their way from plan to market. We utilise a Markov-switching vector error correction model to allow for multiple regime shifts in the price relationship between wheat and wheat flour in Ukraine from June 2000 to November 2004. The analysis reveals four regimes. The observed temporal pattern of these regimes can be matched with certain political and economic events in Ukraine. In particular, we find a strong link between the 'high uncertainty' regime and discretionary policy interventions in 2003.

The Potential Effects on United States Agriculture of an Avian Influenza Outbreak
Provedor de dados: 31
Autores: Brown,   Scott; Madison,   Daniel; Goodwin,   Harold L., Jr.; Clark,   F. Dustan.
The U.S. poultry industry has spent considerable resources to date preparing for an outbreak of avian influenza in this country. This research quantifies the potential effects of two alternative avian influenza scenarios on the poultry industry. In addition, this research looks at effects on other agriculture sectors including the loss of feed demand from an outbreak and the impacts on aggregate measures like farm income and consumer food expenditures. The economic sector model maintained by the Food and Agricultural Policy Research Institute (FAPRI) is employed for these scenarios.

Long-term Global Agricultural Output Supply-Demand Balance and Real Farm and Food Prices
Provedor de dados: 31
Autores: Tweeten,   Luther G.; Thompson,   Stanley R.
Global food demand is estimated from population projections of the United Nations and food supply is projected from Food and Agriculture Organization yield data to quantify the global food supply-demand balance for 2025 and 2050. The eight food categories examined account for 95 percent of global food consumption.  Results indicate that the historic era of secularly falling real food prices is over. The real price of corn, for example, is not expected to fall over the next four decades at the annual rate of 1.3 percent that it fell annually from 1960 to 2006. The analysis foresees future real food prices fluctuating around a flat or rising trend. Slowed national economic growth from flat or rising real food prices may be little more than an irritant for...

Market Valuation of Preconditioning Feeder Calves
Provedor de dados: 31
Autores: Avent,   R. Keith; Ward,   Clement E.; Lalman,   David L.
Preconditioning calf programs, while not new, are becoming more prevalent. They provide benefits to cow-calf producers while adding value for feeder cattle buyers. However, questions remain regarding the economic costs and returns of such programs. A model was estimated with data from three consecutive-day sales, to determine the value that buyers place on preconditioning programs and related feeder cattle traits. Our results indicate that price premiums, although evident, appear to be insufficient by themselves to cover the marginal costs of preconditioning.

Combining Supply and Demand Estimates for Ecosystem Services from Cropland
Provedor de dados: 31
Autores: Ma,   Shan; Swinton,   Scott M.; Lupi,   Frank.
Payment-for-Ecosystem-Services (PES) programs are gaining appeal as flexible approaches to inducing the voluntary provision of ecosystem services (ES). Farmers, who manage agricultural ecosystems, provide important nonmarket ecosystem services to the public by their choice of production inputs and management practices. Although there exist various PES programs in the United States and Europe, we are aware of none that was designed based on a comprehensive understanding of the underlying supply and demand of ecosystem services. Taking advantage of unique, coupled datasets of stated preferences, this paper combines a supply-side cost function of farmers’ willingness to adopt practices that provide increased ES with a demand-side social benefit function of...

Estimating the Market Effect of a Food Scare: The Case of Genetically Modified StarLink Corn
Provedor de dados: 31
Autores: Carter,   Colin A.; Smith,   Aaron D.
Genetic modification of crops has revolutionized food production, but it remains controversial due to food safety and environmental concerns. A recent food safety scare provides a natural experiment on the corn market's willingness to accept unapproved genetically modified organisms. In 2000, a genetically modified corn variety called StarLink was discovered in the food-corn supply, even though it was not approved for human consumption. To estimate the price impact of this event, we develop the relative price of a substitute method, which applies not only to the StarLink event but also to rare events in other markets. We apply this method to measure the price impact of the StarLink contamination on the U.S. corn market. We find that the contamination led...

Autores: Weitzel,   Enno-Burghard; Keskin,   Gulsen; Brosig,   Stephan.
Tomatoes have the largest share among fruits and vegetables, which add substantially to the gross agricultural product in Turkey. We describe the structure and development of this sector from the year 1990 onwards, covering farms in primal production, trade facilities, processing firms, and marketing channels. An analysis of retail prices for table tomatoes in 22 provinces and their dynamics follows. Finally we employ a threshold vector error-correction model to analyse integration among the markets for table tomatoes in the presence of transaction costs. The results show a ring of integrated provinces along the coasts of Turkey, while the interior provinces are rather separated. In some cases price transmission only occurs when deviations from an...

Discussion: Commodity Price Discovery: Problems That Have Solutions or Solutions That Are Problems
Provedor de dados: 31
Autores: Fortenbery,   T. Randall.
This paper examines three invited papers focused on commodity prices. Public responses to high nominal commodity prices and perceived increases in price risk have ranged from attempts to assign blame, attempts to change contracting arrangements, and development of public policy that ‘‘protects’’ the market from future occurrences of unacceptable behavior. Interestingly, a result of increased commodity price volatility has suggested that futures markets no longer ‘‘work.’’ This is ironic given that futures markets initially came into existence as tools for managing the negative impacts of commodity price risk. In response to perceptions of market failure some are looking for strategies to regulate the who and how of futures trading.

Consumer Attitudes, Willingness to Pay and Revealed Preferences for Different Egg Production Attributes: Analysis of Canadian Egg Consumers
Provedor de dados: 31
Autores: Goddard,   Ellen W.; Boxall,   Peter C.; Emunu,   John Paul; Boyd,   Curtis; Asselin,   Andre; Neall,   Amanda.
The Canadian egg industry has introduced a number of specialty eggs, including Omega-3, organic, free run/range, vitamin enhanced and vegetarian over the past few decades. These eggs are generally sold at prices higher than the ‘normal’ egg and there has been little analysis of the consumer awareness of and interest in purchasing these eggs. All previous econometric analysis of the Canadian egg market has assumed eggs and consumers are homogeneous. This study makes use of Stated preference and Revealed preference data to model the consumer interest in the different egg types. Stated preference surveys were conducted in two separate years: 2005 during which consumers were surveyed on their interest in Omega-3 and Vitamin Enhanced eggs relative to ‘normal’...

World Soybean Demand: An Elasticity Analysis and Long-Term Projections
Provedor de dados: 31
Autores: Masuda,   Tadayoshi; Goldsmith,   Peter D.
Soybeans are one of the most valuable crops in the world and are characterized by their multi-purpose uses: food, feed, fuel and other industrial usages such as paint, inks, and plastics.  Out of 183.9 million tons of world supply/demand of soybeans in 2001-03 year, about 10% of them were directly consumed as food (5.9%) or feed (3.8%) but 84.2% of them were crushed into soyoil and soymeal.  Soyoil is mainly processed to vegetable oil for human consumption and recently used as a biodiesel feedstock.  Soymeal is used not only as feed for livestock (especially for pork and poultry due to its low fiber level) and aquaculture, but also as a good source of protein for the human diet in a variety of forms in different cultures.  This paper analyzes the...

This article investigates the potential gains to the U.S. meat sector with the implantation of the U.S. National Animal Identification System (NAIS). The focus is on the effect that the NAIS could have on consumers’ risk perception about eating meat. System of demand equations are estimated using time series of food safety indexes variables used as proxies for consumers’ reactions to news on meat safety issues. The series of food safety indexes are built on the basis of the number of food safety news reported in top U.S. newspapers. Using the preferred model estimates, three scenarios are constructed in order to account for the cases wherein the NAIS is not implemented, is implemented only for beef and is implemented for beef and pork. The differences in...

Consumer Purchasing Behavior in Response to Media Coverage of Avian Influenza
Provedor de dados: 31
Autores: Beach,   Robert H.; Zhen,   Chen.
Consumer concerns regarding food safety can have substantial impacts on their consumption patterns. Thus, understanding consumer response to food safety information is important for quantifying consumer response to food safety events, predicting market impacts, and developing appropriate risk communication strategies. Flexible demand systems have gained much popularity in analyzing effects of food safety outbreaks on consumer demand because of their ability to capture interactions between the demand for substitutable and complementary goods. Using Italian scanner data on meat sales, we show the economic importance of accounting for the impact of avian flu outbreaks on group expenditures for meats in a dynamic Almost Ideal Demand System (AIDS) specification...

Competition between the U.S. and West Africa in International Cotton Trade: A Focus on Import Demand in China
Provedor de dados: 31
Autores: Muhammad,   Andrew; McPhail,   Lihong Lu; Kiawu,   James.
We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that African cotton producers are ill affected by U.S. cotton subsidies, our focus is the price competition between the C4 countries (Benin, Burkina Faso, Chad and Mali) and United States in China. Demand estimates are used to project how U.S. prices affect China’s imports by country. In comparing demand projections, results show that the relationship between the United States and the C4 has more to do with how U.S. prices can affect global prices rather than any substitute or competitive relationship in the Chinese market.

Zusammenfassung: In der vorliegenden Studie erfolgt eine regional differenzierte Analyse der Milchproduktion. Grundlage sind neben zahlreichen agrarstatistischen Quellen auch Expertenpanels in ausgewählten Regionen. Es werden Schlussfolgerungen über die künftige Standortorientierung der Milchproduktion innerhalb Deutschlands abgeleitet und mögliche Begleitmaßnahmen zum Quotenausstieg bewertet.  Die Abschaffung der kleinräumigen Quotenhandelsgebiete hat Produktionsverlagerungen über Ländergrenzen hinweg ermöglicht. Es ist zu erwarten, dass sich die Milchproduktion weiter auf wenige Produktionszentren verstärkt. Die Milchproduktion wird somit vermehrt auf Grünlandstandorte wandern; allerdings gibt es auch Grünlandstandorte, die Produktionsanteile verlieren....

POST-URUGUAY ROUND PRICE LINKAGES BETWEEN DEVELOPED AND DEVELOPING COUNTRIES: THE CASE OF RICE AND WHEAT MARKETS
Provedor de dados: 31
Autores: Yavapolkul,   Navin; Gopinath,   Munisamy; Gulati,   Ashok.
The Uruguay Round Agreement on Agriculture attempted to lower distortions in the global agricultural markets. However, the significant fall in commodity prices in late 1990s may have reduced the incentives for both developed and developing countries to better integrate into the world markets. This study analyzes price linkages and adjustment between developed and developing countries during the post-Uruguay Round period. Prices of two key commodity markets, long-grain rice and medium-hard wheat, are assembled for major exporters and producers. Results from the multivariate cointegration analysis suggest partial market integration between developed and developing countries in the post-Uruguay Round period. Developed countries are found to be price leaders...

Meat demand flexibilities for Tanzania: Implications for the choice of long-term investment
Provedor de dados: 31
Autores: Kaliba,   Aloyce R.
This study uses the inverse almost ideal demand system (IAIDS) to estimate demand flexibilities for beef, small ruminant (sheep and goat) meat, pork and poultry in Tanzania. Own uncompensated price flexibilities were less than one in absolute value, implying that both direct and indirect induced price effect through a change in total expenditure have little impact on budget shares. Estimated scale flexibilities were all negative, suggesting that increases in income will increase the quantities of meat consumed. Production of small ruminant meat was the most attractive investment compared to other meat commodities.

Market Impacts of Adopting Herbicide-Resistant Rice in the Southern United States
Provedor de dados: 31
Autores: Fuller,   Frank H.; Annou,   Mamane Malam; Wailes,   Eric J.
Herbicide-resistant (HR) rice varieties offer U.S. rice producers a powerful tool for control of red rice infestations.  However, improved weed control can shorten crop rotations and boost yields, resulting in expanded rice production and lower domestic market prices.  Declining market returns diminish the benefits of HR rice adoption and substantially reduce net returns for nonadopters.  More competitive prices increase U.S. rice exports, causing a slight decline in world rice prices.  The dependence of the rice marketing loan program on world prices prevents loan deficiency payments from adequately offsetting producers’ market revenue losses.  U.S. consumers gain from lower rice prices.

Valuing Fed Cattle Using Objective Tenderness Measures
Provedor de dados: 31
Autores: Riley,   John Michael; Schroeder,   Ted C.; Wheeler,   Tommy L.; Shackelford,   Stephen D.; Koohmaraie,   Mohammad.
Beef tenderness is critical in consumer satisfaction with beef steak products. Current fed cattle valuation systems do not differentiate carcasses based upon tenderness variation. However, considerable research indicates consumers are willing to pay more for tender relative to tough beef steak. This article develops a tenderness-augmentation to current fed cattle grid pricing systems. Using a large set of actual carcasses, we determine that a tenderness-augmented price grid would reorder fed cattle value by on average nearly $5.00/cwt dressed relative to current valuation methods. Substantial opportunity is present to improve beef tenderness through new price signals to producers.

Trade Liberalization and Agricultural Terms of Trade in China: Price Scissors Revisited
Provedor de dados: 31
Autores: Carter,   Colin A.; Zhu,   Jing.
With China’s accession to the WTO, concerns have arisen over the possible negative welfare impacts on domestic agricultural producers. The broad concern is that China’s domestic agricultural prices will be pushed down even further, leading to a greater widening of the gap between rural and urban incomes. It is widely believed that declining price ratio of agricultural to industrial products, the so-called “price scissors”, is one of the major reasons for increasing rural-urban income differences over the past decades. Therefore, improving the terms of trade in favor of agricultural products is a broad policy goal in China. But is this possible with the country joining the WTO?  While there is a general perception that the price scissors have negatively...

Dynamic Effects of Grain and Energy Prices on the Catfish Feed and Farm Sectors
Provedor de dados: 31
Autores: Muhammad,   Andrew; Zheng,   Hualu.
This study examines the dynamic effects of grain prices and energy prices on catfish feed prices and the price of food-sized catfish at the farm level. Using the autoregressive distributed lag model and bounds testing procedure, a long-run relationship between feed and farm prices and their determinants was confirmed. Given the effect of corn and soybean meal prices on catfish feed prices, and catfish fish feed prices on farm prices, the long-run responsiveness of feed prices to a percentage increase in U.S. ethanol production is 0.325, and the responsiveness of catfish farm prices is 0.064. Although both feed and farm prices increase with ethanol production, the relatively small responsiveness of farm prices when compared with feed prices suggests that...

The Value of Third-Party Certification of Preconditioning Claims at Iowa Feeder Cattle Auctions
Provedor de dados: 31
Autores: Bulut,   Harun; Lawrence,   John D.
After controlling a variety of feeder cattle characteristics and market and sale conditions in Iowa feeder auctions, the price premiums for preconditioning claims (vaccinations and minimum 30 days of weaning) with and without third-party certification (TPC) are estimated as $6.12/cwt and $3.35/cwt, respectively.  These premiums differ statistically (p&lt;0.0001), and their difference exceeds the average participation cost of TPC ($1/cwt).  This indicates that TPC is valued in the market to credibly signal preconditioning investment under asymmetric information.

Prospects of Chinese Grain Supply and Demand in 2010: A Regionalized Multimarket Model Simulation and Policy Implication
Provedor de dados: 31
Autores: Lu,   Wencong C.; Kersten,   Lutz.
Based on China's Agricultural Regional Market Equilibrium Model (CARMEM), the paper projects the production and consumption of rice, wheat and maize in China toward 2010 at both national and regional level under two different scenarios. The results show that China can ensure a stable grain market development under more liberalized internal and external conditions. Transmission of the world market prices as projected by the World Bank (2003) to the Chinese domestic market would lead to a long-run recovery of the growth in grain production. Total production of paddy rice, wheat and maize is forecast to increase from 386 million tons in the base period 2002 to over 420 million tons in 2010. However, the rate of grain self-supply will be 91% due to higher...

Plagiarism Without Apology--Systematic Integration of Available Information in a Long Run Agricultural Outlook
Provedor de dados: 31
Autores: Witzke,   Heinz Peter; Britz,   Wolfgang.
In the context of a long run agricultural outlook on behalf of the European Environmental Agency a new methodology has been developed to systematically integrate external forecasts into a quite detailed agricultural sector model. External forecasts usually provide estimates for the exogenous variables in modelling work and frequently they are also used for comparisons and potential reassessment of empirical specifications. The innovative characteristic of this study is that expert forecasts have been used to specify parameter changes expressing structural change affecting behavioural functions. The outlook was therefore set up as a simultaneous estimation and forecasting effort which permitted to integrate various, usually contradictory expert forecasts...

This study examines retail fluid milk products purchase data from Nielsen 2005 home scan data. The demand for seven categories of fluid milk products were estimated: whole milk, whole flavored milk, reduced fat milk, flavored reduced fat milk, buttermilk, canned milk and all other fluid milk products.  Analyses of the purchases of seven fluid milk categories based on the Nielsen 2005 home scan retail data are used to determine the roles marital status, age, race, education, female employment status and location play in the empirical estimations of aggregate demand elasticities.  To derive the demand elasticities, a censored translog demand system is used.  The results reveal that price and income are the main determinants of demand for fluid milk products...

Autores: Jayne,   Thomas S.; Rashid,   Shahidur.
Crop production forecasts are widely recognized as an important input into food balance sheets and for anticipating production shortfalls. However, the role of accurate crop production forecasting systems in mitigating food price instability and transitory food insecurity is often under-appreciated. This paper explains how crop production forecasting systems affect price instability and risks, and how they can be improved to stabilize the food system.

Autores: Asche,   Frank; Guttormsen,   Atle G.; Kristofersson,   Dadi; Roheim,   Cathy A.
A frequently encountered problem in import demand estimation is how to account for competition between imports and domestic production. Traditionally, use of the Armington model has been a way to handle this problem. This is a disaggregate model which distinguishes commodities by country of origin with import demand determined in a separable two-step procedure. The model appears frequently in analysis of international agricultural markets. However, the Armington model relies on a set of weak separability assumptions, which several authors have shown to be highly questionable. In this paper, a new aggregation theorem, the Generalized Composite Commodity Theorem (GCCT), is applied to test whether imports can be treated as a separate group. An advantage with...

Verifying Credence Attributes in Livestock Production
Provedor de dados: 31
Autores: Olynk,   Nicole J.; Tonsor,   Glynn T.; Wolf,   Christopher A.
Livestock producers can respond to increasing consumer demand for certain production process attributes by providing verifiable information on the practices used. Consumer willingness to pay data were used to inform producer decision-making regarding selection of verification entities for four key production process attributes in the production of pork chops and milk. The potential for informing farm-level decision-making with information about consumer demand for product and production process attributes exists beyond the two products assessed as example cases in this analysis.

Modeling Beef Quality Heterogeneity
Provedor de dados: 31
Autores: Lusk,   Jayson L.; Norwood,   F. Bailey.
The effects of various supply and demand shifts on beef price, quantity, and industry welfare have been widely studied under the assumption of beef quality homogeneity.  In this paper, we construct a model of the beef sector that incorporates differences in beef quality.  The model is used to analyze the effect of supply and demand shifts on changes in prices and quantities of high-and low-quality beef and changes in revenue accruing to producers of high-and low-quality beef.  Model results indicate that supply and demand shocks have the potential to alter the average quality of beef on the market and the price premium charged for high-quality beef, which has important implications for retailers selling quality-differentiated beef and producers selling...

Price volatility on the German Agricultural Markets
Provedor de dados: 31
Autores: Ledebur,   Oliver von; Schmitz,   Jochen.
In this contribution, the development of price volatility on German agricultural markets is analyzed. We quantify the degree of price volatility for selected German agricultural markets and determine how it evolves over time and search for policy driven structural changes in volatility levels measured by the historical volatility. Based on annualised historical volatilities t test were performed to identify if the change in the volatility levels show any relationship to the process of reform of the CAP. An increase in volatility could be identified for the main German markets regulated by the Common Market Organisations. A positive relationship among the reform process of the CAP and the changes of the volatility levels could be identified particularly for...

Impact Of Greenhouse Gas Abatement Targets On Agricultural Activity
Provedor de dados: 31
Autores: Donnellan,   Trevor; Gillespie,   Patrick; Hanrahan,   Kevin F.
As part of its continuing commitment to address the causes of climate change, the EU has agreed reduction targets for greenhouse gas (GHG) emissions to be achieved by 2020. In the case of Ireland the target is a reduction of 20 percent relative to the 2005 level. Agriculture is a major source of GHG emissions in Ireland, comprising 26.8 percent of total GHG emissions in 2007. Understanding the scale and cost of the decrease in agricultural production required to achieve this reduction in GHG emissions is particularly important, as is the comparison of the cost of this approach with a range of possible other means of achieving emissions reductions in the sector. This study finds that, even with reduced fertiliser usage and more extensive production...

Autores: Levedahl,   J. William; Reed,   Albert J.
This paper combines expressions for infant formula retail price flexibilities of the contract brand with respect to the rebate and participant demand presented by Reed and Levedahl (2012)with historical data on rebates and participant demand to calculate how the magnitude of net taxpayer costs has been affected by changes in rebates and participant demand. These results are used to compare the relative impact of these variables on the net cost to taxpayers of WIC infant formula and to evaluate how effective sole-source contracts have been at containing taxpayer costs.

Behavior of subsistence producers in response to technological change- The elasticity of cassava production and home consumption in Benin
Provedor de dados: 31
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...

Devil or Angel? The Role of Speculation in the Recent Commodity Price Boom (and Bust)
Provedor de dados: 31
Autores: Irwin,   Scott H.; Sanders,   Dwight R.; Merrin,   Robert P.
It is commonly asserted that speculative buying by index funds in commodity futures and over–the–counter derivatives markets created a ‘‘bubble’’ in commodity prices, with the result that prices, and crude oil prices, in particular, far exceeded fundamental values at the peak. The purpose of this paper is to show that the bubble argument simply does not withstand close scrutiny. Four main points are explored. First, the arguments of bubble proponents are conceptually flawed and reflect fundamental and basic misunderstandings of how commodity futures markets actually work. Second, a number of facts about the situation in commodity markets are inconsistent with the existence of a substantial bubble in commodity prices. Third, available statistical evidence...

As events in the 2008/09 season have amply demonstrated, instability in staple food market                         remains a major problem in Zambia. A rise in world food price levels and instability, which is                                      projected to occur in the near future according to several international institutes, will make it                                      all more important for developing countries to consider the strengths and weaknesses of                                      alternative approaches for buffering their domestic food systems from potential high volatility                                      in world markets.

The Impact of Food Price Shock on Heterogenous Credit Constrained Firms
Provedor de dados: 31
Autores: Ciaian,   Pavel; Kancs,   d'Artis.
The paper analyses how the rising agricultural prices affect heterogenous farm access to inputs and production under credit market imperfections in the CEE transition countries. Using farm level panel data which contains 37416 observations, we estimate a farm credit constraint equation and find that small individual farms (IF) are on average more credit constrained than large corporate farms (CF). Using the estimated parameters we simulate the effect of the recent food price shock. Our results suggest that in the presence of credit market imperfections, the relatively less credit constrained CF benefit more from higher output prices than IF, as they are able to expand their production more flexibly. These findings have implications for the developing...

Effects of Agricultural Policy Measures on Gross Transfers to Farmers: Intertemporal and Interregional Evidence from the CAP
Provedor de dados: 31
Autores: Hansen,   Heiko.
This paper analyses the effects of the Common Agricultural Policy (CAP) on gross transfers over time and across regions. Depending on the type of instrumentation to support agriculture, the volatility of gross transfers differs. While assistance arising from market price supports, regarded as independent from the world market levels, fluctuates intertemporally, direct payments are constant. Empirical findings for the CAP show a reduction of the transfer volatility on grain markets. For beef and veal this effect is not significant, because price support is still large in these markets. If agricultural support is biased in favour of specific commodities, territorial heterogeneity leads to an uneven distribution. By applying a regionalised concept of producer...

A Censored Incomplete Demand System is applied to household expenditures for edible oil in India. The results show that edible peanut oil is still a luxury good in India, whereas expenditure elasticities for other edible oils are relatively low. The food habit, location, education of household heads, and other demographic variables have significant effects on the choice of edible oils.

Autores: Jin,   Hyun Joung; Miljkovic,   Dragan.
We analyze the movement of farm prices relative to other commodity prices in the period 1913:1-2003:12, investigating the number and time of structural breaks and discussing likely causes of structural breaks in the relative farm prices.  Bai and Perron's (1998, 2003) multiple structural change test with a dynamic programming algorithm is used.  This test makes it possible to have an efficient computation of the estimates of the break points as global minimizers of the sum of squared residuals.  We find 6 structural breaks when we consider only the mean process and 2 breaks when we consider the mean and autoregressive processes.  Possible causes for these breaks are discussed.

This research furthers the assessment of consumer demand for locally produced foods, while also considering a host of other food attributes that may interact to influence consumer utility. Using stated preference data from a choice-based conjoint analysis survey instrument, we estimate willingness-to-pay for processed food products (blackberry jam) that are differentiated with respect to their branding, the location of their production, certification as organically produced, branding as a product of a small family farming association, and carrying a State Proud certification. Although price is the most important single attribute influencing consumer choice for our sample, consumers also were willing to pay more for food products produced in their state or...

Autores: Arfini,   Filippo; Donati,   Michele; Menozzi,   Davide.
The Tobacco CMO (Common Market Organization) is involved in a intense debate between the European tobacco industry and those who are against to a crop whose transformed product is dangerous to the health. European institutions have shown a strong interest in this complex issue introducing two Reforms (1992 and 1998) and one revision in 2004. This paper aims to analyse and investigate the socio-economic impact of the tobacco CMO Reform of 2004 in Italy, across the scenarios proposed by the EC Commission (2004), both on the tobacco production and processing sector. The considered socio-economic indicators are harvested surfaces, farm income and overall employment, while the sample of farms used in this research belong to the FADN–Italy sample.

Autores: Niemi,   Jyrki S.; Fahlbeck,   Erik; Hofreither,   Markus F.
Ten years ago, Austria, Finland, and Sweden joined the EU. The application of the Common Agricultural Policy (CAP) caused major repercussions on the agricultural sectors of the entering countries. This article analyses the welfare effects of accession to the EU on the agricultural markets in Austria, Finland and Sweden in a simple supply and demand framework, which is kept strictly identical across all three countries. The quantitative results of the study are derived by using standard partial equilibrium comparative static analysis in the Marshallian economic surplus framework. Using this method, the welfare effects are calculated for eight major cereal and livestock commodities produced in Austria, Finland, and Sweden by comparing the evolution of the...

Autores: Kim,   In Seck; Plain,   Ronald L.; Bullock,   J. Bruce; Jei,   Sang Young.
The imputed pig death loss contained in the reported monthly U.S. Department of Agriculture (USDA) pig crop data over the December 1995–June 2006 period ranged from 24.93% to 12.75%. Clearly, there are substantial measurement errors in the USDA monthly pig crop data. In this paper, we present alternative monthly U.S. pig crop data using the biological production process, which is compatible with prior knowledge of the U.S. hog industry. Alternative pig crop data are applied to a slaughter hog model and tested comparatively to USDA pig crop. Test results reject the validity of USDA pig crop data in favor of the alternative data.

What are the long-term drivers of food prices? Investigating improvements in the accuracy of prediction intervals for the forecast of food prices
Provedor de dados: 31
Autores: Benjamin,   Catherine; Houee-Bigot,   Magalie; Tavera,   Christophe.
Over the last few years, the prices of the main agricultural raw materials have been highly volatile. The situation is unprecedented, both in the magnitude of the upward and downward volatility observed, and in the number of agricultural commodities affected. Various factors are contributing to these contrasting shifts: the role of emerging countries, changing dietary habits, an increase in energy demand related to the boom in biofuels, adverse weather conditions and speculation. In this paper we try to capture long-term relationships between crop prices and crude oil price using a partial equilibrium and times series method.  The study finds little empirical evidence that the crude oil price have a significant influence on the variation of major vegetable...

Price volatility in ethanol markets
Provedor de dados: 31
Autores: Serra,   Teresa; Zilberman,   David.
Our paper looks at how price volatility in the Brazilian ethanol industry changes over time and across markets. Demand and supply forces in the energy and food markets are likely to ensure that crude oil, ethanol and feedstock prices co-move in the long-run. Hence, when assessing price volatility changes and spillovers in the ethanol industry, one should also pay attention to the notion of cointegration. Until recently, the methods proposed to estimate cointegration relationships, have not explicitly considered time varying volatility in the data. Seo (2007) suggests an estimator of the cointegration vector that explicitly models conditional heteroskedasticity. More specifically, he proposes a maximum likelihood estimator that estimates the error...

ASSET FIXITY IN U.S. AGRICULTURE: ROBUSTNESS TO FUNCTIONAL FORM
Provedor de dados: 31
Autores: Lin,   Ni; Shumway,   C. Richard.
The sensitivity of asset fixity conclusions, input adjustment rates, and elasticities to choice of functional form is examined using a dynamic dual model of U.S. agriculture. A very general initial specification allows tests of instantaneous adjustment to be performed for every input.  Test results are mixed across functional forms for all inputs except real estate, which is consistently found to be quasi-fixed. Important differences in estimated adjustment rates and elasticities are also found among the functional forms. The translog has higher likelihood support than either the generalized Leontief or normalized quadratic functional forms for this dynamic model specification and data set.

On the Dynamic Relationship between U.S. Farm Income and Macroeconomic Variables
Provedor de dados: 31
Autores: Baek,   Jungho; Koo,   Won W.
This study examines the short- and long-run effects of changes in macroeconomic variables—agricultural commodity prices, interest rates and exchange rates—on the U.S. farm income. For this purpose, we adopt an autoregressive distributed lag (ARDL) approach to cointegration with quarterly data for 1989–2008. Results show that the exchange rate plays a crucial role in determining the long-run behavior of U.S. farm income, but has little effect in the short-run. We also find that the commodity price and interest rate have been significant determinants of U.S. farm income in both the short- and long-run over the past two decades.

Autores: Ng,   Desmond W.
As changes in modern agribusiness markets have placed increasing emphasis to the study of structural change processes, this research advances an agent based model to examine transitions from a spot market exchange to a vertically coordinated arrangement in a supply chain system. This agent base simulation model draws from the subjective theme of Austrian entrepreneurship, behavioral theories of the firm and social networks. The results of this agent based simulation model indicate that structural change occurs with market structures that facilitate information transmission rather than from incentive based contractual arrangements.

Price volatility in ethanol markets
Provedor de dados: 31
Autores: Serra,   Teresa; Zilberman,   David.
Our paper looks at how price volatility in the Brazilian ethanol industry changes over time and across markets by using a new methodological approach suggested by Seo (2007). The main advantage of Seo’s proposal over previously existing methods is that it allows to jointly estimate the cointegration relationship between the price series investigated and the multivariate GARCH process. Our results suggest that crude oil prices not only influence ethanol price levels, but also their volatility. Increased volatility in crude oil markets results in increased volatility in ethanol markets. Ethanol prices, on the other hand, influence sugar price levels and an increase in their volatility levels also impacts, though less strongly, on sugar markets.

This study uses a stochastic simulation approach based on a partial equilibrium structural econometric model of the world fiber market to examine the effects of a removal of U.S. cotton programs on the world market. The effects on world cotton prices and African export earnings were analyzed. The results suggest that on average an elimination of U.S. cotton programs would lead to a marginal increase in the world cotton prices thus resulting in minimal gain for cotton exporting countries in Africa.

Beginning January 1, 2015, conventional cage housing for egg-laying hens is scheduled to be prohibited in California. We consider the economic implications of the new hen housing regulations on the California shell egg industry. Our data show that egg production is more costly using noncage systems than conventional cages. The main result of the new regulations will be a drastic reduction in the number of eggs produced in California, a large increase in egg shipments from out of state, little if any change in hen housing for eggs consumed in California, and little change in egg prices in California.

Factor Price Disparity and Retained Ownership of Feeder Cattle: An Application of Feedlot and Carcass Performance Data to Farm-Level Decision Making
Provedor de dados: 31
Autores: White,   Brad J.; Anderson,   John D.; McKinley,   W. Blair; Parish,   Jane.
In this study, we used farm-level data from a university feed-out program to evaluate how the value of feeder cattle ultimately realized through finishing and grid pricing differs from their market value at public auction. Consistent with the theory of factor price disparity results indicate that significant risk premiums exist in the feeder cattle market. Producers of cattle with known feedlot performance, carcass potential, or both might be better off retaining ownership of their calves or marketing them in a way that communicates the information that is known about their potential performance directly to the buyer.

Food Calorie Intake under Grain Price Uncertainty: Evidence from Rural Nepal
Provedor de dados: 31
Autores: Pan,   Suwen; Fang,   Cheng; Rejesus,   Roderick M.
This study evaluates the effects of grain output price uncertainty on the farm income of rural households and, consequently, how this uncertainty influences caloric intake through changes in farm income. Using a rural household data set, augmented with output price uncertainty measures calculated from historical time-series data, we find that grain output price uncertainty tends to decrease crop production income of rural households. In addition, we find that higher crop income from production increases calorie intake of rural households. Taken together, these results suggests  that output price uncertainty during the production process may tend to reduce caloric intake of rural Nepalese households since the price uncertainty negatively affects the crop...

SOURCES OF GROWTH AND SUPPLY RESPONSE: A CROSS-COMMODITY ANALYSIS OF CHINA'S GRAIN SECTOR
Provedor de dados: 31
Autores: Colby,   Hunter; Diao,   Xinshen; Somwaru,   Agapi.
A growth accounting method is used to analyze the sources of growth in China's rice, wheat, corn and soybeans, the four most important crops in China's grain sector, during 1978-97.  A large TFP contribution to growth in grain production is found in the period immediately following China's rural economic reform (1978-85).  In recent years the growth rate of TFP falls sharply, contributing less than 20 percent of growth in grain production, as increased use of inputs became the major engine of growth.  If the current government policy environment remains unchanged, China's grain production will become increasingly costly and constrain future growth and competitiveness in world grain markets.  The supply response of the four grains is estimated using a...

Are Staple Foods Becoming More Expensive For Urban Consumers In Eastern And Southern Africa? Trends in Food Prices, Marketing Margins, and Wage Rates in Kenya, Malawi, Mozambique, and Zambia
Provedor de dados: 31
Autores: Mason,   Nicole M.; Jayne,   Thomas S.; Donovan,   Cynthia; Chapoto,   Antony.
The world food and financial crises threaten to undermine the real incomes of urban consumers in eastern and southern Africa. This study investigates patterns in staple food prices, wage rates, and marketing margins for urban consumers in Kenya, Malawi, Mozambique, and Zambia between 1993 and 2009. There is high correlation among wage rate series for various government and private sector categories. We find that average formal sector wages rose at a faster rate than retail maize meal and bread prices in urban Kenya and Zambia between the mid-1990s and 2007. Although the 2007/08 food price crisis partially reversed this trend, the quantities of staple foods affordable per daily wage in urban Kenya and Zambia during the 2008/09 marketing season were still...

Country and border effects in the transmission of maize prices in Eastern Africa: evidence from a semi-parametric regression model
Provedor de dados: 31
Autores: Ihle,   Rico; von Cramon-Taubadel,   Stephan; Zorya,   Sergiy.
This study uses a rich dataset of 85 market pairs between January 2000 and October 2008 for Kenya, Tanzanian and Uganda, the three largest member countries of the East Africa Community, to analyze the factors determining national and cross-national maize price transmission. Although the three countries are members of the community’s customs union and they each claim to pursue maize trade without borders, their agricultural trade policies still differ, thus affecting prices and trade flows to different extents. This analysis extends the existing border effects literature in three ways. First, it assesses the magnitude of price transmission, instead of analyzing trade flows or price variability. Second, distance is shown to have a significant impact on price...

The Impact of the New York State Retail Milk Price Regulation  on Farm-to-Retail Price Transmission and  Supermarket Pricing Strategies in Metropolitan Fluid Milk Markets
Provedor de dados: 31
Autores: Bolotova,   Yuliya; Novakovic,   Andrew M.
The New York State Milk Price Gouging Law establishes that the retail prices of fluid milk products are not to exceed 200% of the prices that NYS milk processors pay for Class I milk. The enforcement of this law significantly affected the nature of the Class I fluid milk price transmission process and the milk pricing strategies of supermarkets in the five largest cities in New York State: New York City, Albany, Syracuse, Buffalo and Rochester.   During the pre-law period, supermarkets used a retail price-stabilization strategy, as evidenced by asymmetric Class I fluid milk price transmission. In contrast, supermarkets use a retail profit stabilization strategy during the law period.   This variation of retail milk price control actually creates an...

How to Derive Market Impacts of the Luxembourg Agreement on the German Beef Market  - A Synthetic Uniform Model versus an Econometric Country Specific Model
Provedor de dados: 31
Autores: Salamon,   Petra.
The paper discusses two partial equilibrium models, one is a synthetic model (GAPsi) and the other an econometrically estimated model (AG-MEMOD). While the synthetic model incorporates only price impacts and some shifts, the econometric model also reflects other influencing factors. Price formation includes policy measures as price wedges, or as explaining variables in key price equations or price transmission equations, which is also true when premiums and decoupling are regarded. When the Luxembourg Agreement is simulated, our example of beef shows that these model differences induce deviations in model results, especially concerning prices and trade.

A Comparative Study of China's and Australia's Cotton Production
Provedor de dados: 31
Autores: Zhao,   Xufu; Tisdell,   Clement A.
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,...

Dynamic Adjustment of U.S. Agriculture to Energy Price Changes
Provedor de dados: 31
Autores: Lambert,   David K.; Gong,   Jian.
Energy prices increased significantly following the first energy price shock of 1973. Agricultural producers found few short run substitution possibilities as relative factor prices changed. Inelastic demands resulted in total expenditures on energy inputs that have closely followed energy price changes over time. A dynamic cost function model is estimated to derive short and long run adjustments within U.S. agriculture between 1948 and 2002 to changes in relative input prices. The objective is to measure the degree of farm responsiveness to energy price changes and if this responsiveness has changed over time. Findings support inelastic demands for all farm inputs. Statistical results support moderate increases in responses to energy and other input price...

The Demand for Disaggregated Food-Away-from-Home Products
Provedor de dados: 31
Autores: Okrent,   Abigail M.; Alston,   Julian M.
Food away from home (FAFH) is an important component of the demand for food and hence, the nutritional intake of adults and children in the United States. Hence, policies designed to influence nutritional outcomes should address the role of FAFH. However, most studies of the response of demand for food to policy changes have ignored the role of FAFH, which means the estimates must be biased, while those studies that have included FAFH have treated it as a single good, giving rise to potential aggregation biases. In this study we estimate a demand system including a FAFH and alcoholic beverages composite (i.e., the aggregate of the three products modeled in the second stage), along with nine food at home (FAH) products (cereals and bakery products, dairy,...

The U.S. Agricultural Sector and the Macroeconomy
Provedor de dados: 31
Autores: Baek,   Jungho; Koo,   Won W.
The effects of the exchange rate, the U.S. agricultural price, the domestic income, and the interest rate on the U.S. net farm income are investigated in a cointegration framework. For this purpose, the Phillips-Hansen fully-modified cointegration (FM-OLS) procedure is applied to annual data for the period 1957–2008. Results suggest that there exists the long-run equilibrium relationship between the U.S. net farm income and the selected macroeconomic variables. We also find that the exchange rate and U.S. agricultural price are more important than other variables in determining the U.S. net farm income.

Assessing the economic costs of an outbreak of Foot and Mouth Disease on Brittany: A dynamic computable general equilibrium approach
Provedor de dados: 31
Autores: Gohin,   Alexandre; Rault,   Arnaud.
Epizootic outbreaks such as Foot and Mouth Disease are of great concern for agriculture. In this paper, we quantify the potential dynamic impacts of such a disease on Brittany, a French region with a strong livestock sector. We develop a dynamic computable general equilibrium model with rational expectations that allows us to measure the impacts of culling infected animals and restraining movements of live animals on the livestock sectors and downstream food industries. Our results show that economic losses are spread over many periods even with a one-time shock. The impacts on the primary sectors and downstream food sectors do not move in parallel. The food industries suffer most in the first period while the negative impacts on agriculture are mostly...

Natural Protection from International Competition in the Livestock Industry: Analysis, Examples and Vietnam's Pork Market as a Case
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Lapar,   Ma. Lucila A.; Staal,   Steven J.; Que,   Nguyen Ngoc.
In some countries, local agricultural products (particularly livestock products) are shielded from international competition by ‘natural’ factors influencing the purchase of products. These factors include strong local tastes (or preferences) that favour the local product and the absence (or relative absence) of complementary retail outlets or home appliances suitable for storing and preparing potential imported substitutes. The desire for fresh meat rather than chilled or frozen meat, the absence or limited accessibility of supermarket outlets and limited refrigeration possibilities in homes can limit imports into developed countries of meat supplied by developed countries. From consumer’s perspectives these fresh or raw products are significantly...

The Relationship between Oil, Exchange Rates, and Commodity Prices
Provedor de dados: 31
Autores: Harri,   Ardian; Nalley,   Lawton Lanier; Hudson,   Darren.
Exchange rates have long been thought to have an important impact on the export and import of goods and services, and, thus, exchange rates are expected to influence the price of those products that are traded. At the same time, energy impacts commodity production in some very important ways. The use of chemical and petroleum derived inputs has increased in agriculture over time; the prices of these critical inputs, then, would be expected to alter supply, and, therefore, the prices of commodities using these inputs. Also, agricultural commodities have been increasingly used to produce energy, thereby leading to an expectation of a linkage between energy and commodity markets. In this paper, we examine the price relationship through time of the primary...

YIELD RESPONSE TO PRICES: IMPLICATIONS FOR POLICY MODELING
Provedor de dados: 31
Autores: Keeney,   Roman; Hertel,   Thomas W.
We examine the determinants of own-price output supply response in policy models, focusing primarily on the OECD-PEM equilibrium displacement model. Reviewing expert assessments and econometric literature estimates we find that there is evidence to both support and challenge the relatively high supply response of a model like the OECD-PEM. We also consider possible avenues of reconciliation between evidence that supports and challenges the assumed supply response in the OECD-PEM model. Our analysis of supply response in the OECD-PEM case and from reviewing literature leads us to recommend that future econometric investigation be focused on the role of farm household owned resource mobility as it contributes to agricultural supply response.

The Marketing Performance of Illinois and Kansas Wheat Farmers
Provedor de dados: 31
Autores: Dietz,   Sarah N.; Aulerich,   Nicole M.; Irwin,   Scott H.; Good,   Darrel L.
The purpose of this paper is to analyze the marketing performance of wheat farmers in Illinois and Kansas over 1982–2004. The results show that farmer benchmark prices for wheat in Illinois and Kansas fall in the middle third of the price range about half to three-quarters of the time. Consistent with previous studies, this refutes the contention that Illinois and Kansas wheat farmers routinely market the bulk of their wheat crop in the bottom portion of the price range. Tests of the average difference between farmer and market benchmark prices are sensitive to the market benchmark considered. The marketing performance of wheat farmers in Illinois and Kansas is about equal to the market if a 24- or 20-month market benchmark is used, slightly above the...

Global Food Price Volatility and Spikes: An Overview of Costs, Causes, and Solutions
Provedor de dados: 31
Autores: von Braun,   Joachim; Tadesse,   Getaw.
Since the 2007–08 food crisis, many thoughtful analyses have addressed the causes and impacts of high and volatile international food prices and proposed solutions to the crisis. These studies have covered global as well as local food price dynamics and policy reactions. The food price problem is, however, far-reaching, and its impacts are wide and interrelated. The price formation mechanism has become highly complex and dynamic. Policy actions are politically and economically sensitive. This situation calls for continuous and comprehensive assessments of the problem to provide timely and evidence-based knowledge for policy makers. This paper reviews existing evidence and theories and presents new thoughts and insights from analyses to enlighten the course...

Evidence of non-linear price transmission between maize markets in Mexico and the US
Provedor de dados: 31
Autores: Araujo-Enciso,   Sergio Rene.
The present work provides evidence that non linear co-integration between Mexico and the US maize prices exists, at country and regional level. The models suggest that Mexican prices adjust at changes in US prices. Despite asymmetry was statistically rejected, it is likely that it might occur for thriving parameters different that zero in the error correction term. The results suggest on which way the research might be improved in order to assess such co-integration relationship accurately.

Coping with Systemic Risk in Index-based Crop Insurance
Provedor de dados: 31
Autores: Shen,   Zhiwei; Odening,   Martin.
The implementation of index-based crop insurance is often impeded by the existence of systemic risk of insured losses. We assess the effectiveness of two strategies for coping with systemic risk: regional diversification and securitization with catastrophe (CAT) bonds. The analysis is conducted in an equilibrium pricing framework which allows the optimal price of the insurance and the number of traded contracts to be determined. We also explore the role of basis risk and risk aversion of market agents. The model is applied to a hypothetical area yield insurance for rice producers in northeast China. If yields in two regions are positively correlated, we find that enlarging the insured area leads to an increasing insurance premium. Unless capital market...

U.S. Proposal for WTO Hong Kong Ministerial Conference: What's at Stake for Cotton Producers?
Provedor de dados: 31
Autores: Fadiga,   Mohamadou L.; Mohanty,   Samarendu; Pan,   Suwen; Welch,   Mark.
This study analyzed the cost to U.S. cotton producers of two policy alternatives under which the U.S. seeks to cut its total AMS payments for cotton by 60%. We considered two scenarios; the U.S. decides to act unilaterally versus conducting the policy initiative along with multilateral tariff and subsidy eliminations from the Rest of the World.  The study found a 12% cut in target price and 8% cut in loan rate are necessary to reach the 60% AMS targeted reduction under the unilateral scenario. In that regards, U.S. net farm income decreases considerably despite an appreciation of U.S. farm price.  Under a multilateral trade liberalization from the Rest of the World, a 9% cut in the loan rate and 4% in loan rate are enough to reach the AMS reduction...

This article focuses on the demand system of French farmers concerning pesticides uses. We estimate the demand elasticities of herbicides, insecticides and fungicides with respect to pesticide expenditure, and considering crop differentiation. Then we compare two indexes that are used in agronomic literature to measure the intensity of pesticides uses. We retain a Linear Approximated Almost Ideal Demand System (LA/AIDS) specification. A Full-Information Maximum Likelihood estimation procedure is used for dealing with the problem of censored dependent variable. We consider two cross-sections observed in 2001 and 2006 covering pesticides uses of three crops. We confirm the previous results of the literature that farmers response to price variation is very...

El modelo de ayudas directas en la PAC post-2013: análisis de impactos de escenarios potenciales
Provedor de dados: 31
Autores: Blanco,   Maria; Garcia-German,   Sol; Bardaji,   Isabel.
Following their introduction in 1992, direct payments have become one of the main instruments of the Common Agricultural Policy. The aim of this study is to analyse potential scenarios of harmonization of direct payments in the CAP post-2013. In doing so, we use the CAPRI model, which represents the functioning of agricultural markets at the global level and simultaneously models CAP measures at the EU regional level. Results suggest that while a flatter rate of direct payments would have minor impacts on agriculture at the EU level, it would imply substantial redistributive effects, both across regions and Member States.

An ex-ante analysis of distributional effects of the CAP on western German farm incomes
Provedor de dados: 31
Autores: Deppermann,   Andre; Grethe,   Harald; Offermann,   Frank.
This study is concerned with measuring impacts of the Common Agricultural Policy (CAP) on farm income distribution of western Germany. Not only the sheer contribution of market price support and direct payments as a proportion of income is taken into account, but also the impact of support on production incentives. For this purpose, we apply a modelling system consisting of a partial equilibrium model and a programming model. Based on a comparison of Gini coefficients and a decomposition of overall inequality effects we conclude that liberalization of the agricultural sector leads to a more unequal distribution of family farm income in relative terms, whereas a liberalized market provides a more equal situation in absolute terms.

ASYMMETRY IN RAW MILK SAFETY PERCEPTIONS AND INFORMATION: IMPLICATIONS FOR RISK IN FRESH PRODUCE MARKETING AND POLICY
Provedor de dados: 31
Autores: Knutson,   Ronald D.; Currier,   Russell W.; Ribera,   Luis A.; Goeringer,   L. Paul.
Scientific evidence clearly indicates that consumption of raw milk carries substantial disease-inducing health risks. While federal U.S. policy mandates that milk moving in interstate commerce be pasteurized; within 41 of 50 states, raw milk can be obtained for consumption. Warning labels notwithstanding, a segment of U.S. consumers pays higher prices for higher-risk raw milk than for either organic or conventional milk. The behavioral factors leading to raw milk consumption are explored. The paternalistic regulatory options for reducing the risk associated with drinking raw milk are identified.

Alfalfa Hay Quality and Alternative Pricing Systems
Provedor de dados: 31
Autores: Hopper,   Jared A.; Peterson,   Hikaru Hanawa; Burton,   Robert O., Jr.
Price-quality relationships for alfalfa hay were analyzed by hedonic pricing models using 1996-2001 Wisconsin auction data.  Individual nutrients included in the analysis all affected alfalfa price, with acid detergent fiber accounting for the largest impact.  Alternative pricing models, based on an aggregate quality index or detailed quality information, were similar in their ability to predict price.  However, disaggregating price predictions to account for differences in relative feed value (RFV) and crude protein (CP) indicate that both RFV and CP are important determinants of price and that aggregating the two into a quality index is not warranted.

Impacts of Agri-Environmental Policies on Land Allocation and Land Prices
Provedor de dados: 31
Autores: Guyomard,   Herve; Lankoski,   Jussi E.; Ollikainen,   Markku.
We develop a Ricardian framework with heterogeneous land quality to analyse the effects of agricultural and agri-environmental support policies on land allocation decisions and land prices. Four agri-environmental policy instruments are considered: a uniform area payment, a quality-dependent area payment, a mandatory buffer strip policy and a voluntary buffer strip payment. We also analyse how general tax and monetary policies may affect agricultural land prices. The theoretical framework is illustrated by an empirical model applied to Finnish agriculture. The empirical model shows that macroeconomic factors, such as general tax and monetary policies, may exert a greater impact on land prices than some minor fine-tuning in agrienvironmental policies.

Autores: Baldi,   Lucia; Peri,   Massimo; Vandone,   Daniela.
This paper investigates the long-run relationship between spot and futures prices for corn and soybeans, for the period January 2004 -September 2010. We apply cointegration methodology in the presence of potentially unknown structural breaks in the commodities prices and we then study the causality relationships between spot and futures prices within each specific sub-period identified, with the aim to analyze where changes in spot and futures price originate and how they spread. Empirical estimates highlight the following evidence: i) breaks relate to events that have significantly affected the supply and demand of corn and soybeans for food and energy purposes; ii) subperiods consequently identified express different dynamics in the causal relationship...

The Effects of Mad Cow Disease on U.S. Live Cattle Futures Price
Provedor de dados: 31
Autores: Paiva,   Newton N.
Due to red meat consumption, bovine spongiform encephalopathy (BSE) disease has been a major human health concern since its discovery in 1986.  An event study approach was applied to determine the impact of BSE official events that occurred in the United Kingdom on U.S. live cattle futures prices.  When abnormal returns were aggregated during the course of the events, the price series were adversely affected, mainly after the event day.  This suggests that market reaction was dissipated quickly and that no leakage of information occurred prior to the event.

Decomposing Changes in Agricultural Producer Prices
Provedor de dados: 31
Autores: Liefert,   William M.
This paper develops a method for decomposing changes in agricultural producer prices. The method builds on a procedure used by the World Bank, with the key variables in the decomposition being trade prices, exchange rates, and agricultural trade policies. The main ways by which we expand on the World Bank decomposition procedure are by broadening the analysis of policy effects, and by adding the effect from incomplete transmission of changes in border prices and exchange rates to producer prices, and the effect on prices from interactions between variables as they change simultaneously. We demonstrate the decomposition method by using the Russian poultry market in the late 1990s, and find that the dominant factor in changing the producer price was the...

The Survival of Small-scale Agricultural Producers in Asia, particularly Vietnam: General Issues Illustrated by Vietnam's Agricultural Sector, especially its Pig Production
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Economic growth in more developed countries has resulted in farms increasing their scale of production and becoming more specialized in their production. The sizes of farms have tended to increase, agricultural production has become more capital-intensive, and the percentage of the workforce employed in agriculture has shown a falling trend. This process has been brought about by the operation of market systems and has reduced the number of small-scale agricultural producers. Asia still has a huge number of small-scale agricultural producers. As Asian countries experience economic growth and as market systems become more established in Asia, the survival of Asia’s small-scale agricultural producers is likely to be threatened. Since these producers are...

A regime-switching model for analysis of market integration has been developed that incorporates rate of trade information. An application of the methods to United States–China soybean trade demonstrates that the extended trade information allows better interpretation of market conditions. While the empirical results show that China’s reform efforts since mid 1990s toward an open market have greatly improved United States–China soybean markets integration, about 40% of nontransitional disequilibrium occurrences likely indicate infrastructural limits such as the lack of information availability and limited competition. The United States–China price linkage is observed to be closer after China’s World Trade Organization membership. The link has also been...

The Choice of Technology in Russian Agriculture: An Application of the Induced Innovation Hypothesis
Provedor de dados: 31
Autores: Hockmann,   Heinrich; Kopsidis,   Michael.
Even after more then ten years after the beginning of the transition process, Russian agriculture shows only limited sign of a recovery. Production has not reached the level of the pre-transition period and investment is still on a very low level. In this paper we use the "Theory of Induced Innovation" in order to access the development of production structures in Russia and to identify the major obstacles for restructuring. We argue that due to multiple market failure (capital, labour) and inappropriate institutional arrangements inherited from Soviet times hinder the development of Russian agriculture. Both reasons causes that agricultural enterprises have difficulties with regard to an adjustment of factor input and production corresponding to the real...

Consumer Preferences for Animal Welfare Attributes: The Case of Gestation Crates

Autores: Tonsor,   Glynn T.; Olynk,   Nicole J.; Wolf,   Christopher A.
Animal welfare concerns are having dramatic impacts on food and livestock markets. Here we examine consumer preferences for pork products with a focus on use of gestation crates. We examine underlying consumer valuations of pork attributes while considering preference heterogeneity as well as voluntary and legislative alternatives in producing gestation crate-free pork. Our results suggest that prohibiting swine producers from using gestation crates fails to improve consumer welfare in the presence of a labeling scheme documenting voluntary disadoption of gestation crates. Consumers are found to implicitly associate animal welfare attributes with smaller farms. Preference heterogeneity drives notably diverse consumer welfare impacts when pork produced with...

Estimating a Demand System with Seasonally Differenced Data
Provedor de dados: 31
Autores: Harri,   Ardian; Brorsen,   B. Wade; Muhammad,   Andrew; Anderson,   John D.
Several recent papers have used annual changes and monthly data to estimate demand systems. Such use of overlapping data introduces a moving average error term. This paper shows how to obtain consistent and asymptotically efficient estimates of a demand system using seasonally differenced data. Monte Carlo simulations and an empirical application to the estimation of the U.S. meat demand are used to compare the proposed estimator with alternative estimators. Once the correct estimator is used, there is no advantage to using overlapping data in estimating a demand system.

Impacts of Expanded Ethanol Production on Southern Agriculture
Provedor de dados: 31
Autores: Susanto,   Dwi; Rosson,   C. Parr, III; Hudson,   Darren.
This study analyzes the potential impacts of expanded ethanol production on southern agriculture. Results of regression analysis suggest that acreage planted for field crops (corn, cotton, soybeans, and wheat) is inelastic with respect to relative prices. The results provide statistical evidence of potential significant acreage shifts favoring corn over cotton, soybeans, and wheat. Simulations indicate that higher corn prices will increase corn acreage, but the South continues to be a deficit corn region. U.S. corn production is capable of supplying domestic demand for ethanol, feed for livestock and poultry, and other uses, while maintaining exports at more than 2 billion bushels annually.

U.S. banana demand differentiated by country of origin is estimated using the generalized dynamic Rotterdam model.  Results indicate that dynamic factors play a significant role in determining the allocation of U.S. banana expenditures across exporting sources.  Of particular interest is Guatemala’s increased share and Costa Rica’s decreased share of U.S. banana supply.  A number of factors explained why Guatemala replaced Costa Rica as the leading U.S. supplier in 2007.  (1) Guatemala is the least expensive source on average.  (2) Habit persistence, adjustment costs, and other dynamic factors favor Guatemala’s exports.  (3) Given increases in the relative price of Costa Rica’s bananas, the price competition between Costa Rica and Guatemala is highly...

The potential economic benefits of Bt brinjal hybrids in terms of yield gain, reduction in insecticide-use, and increase in net returns per hectare have been reported in this study. Results have shown that adoption of Bt brinjal hybrids would provide yield gain of 37 per cent and reduction in total insecticide-use of about 42 per cent over non-Bt hybrids. Other benefits like increase in additional brinjal production (30 thousand tonnes), savings from insecticides (` 47 crore) against Fruit and Shoot Borer (FSB), increase in net returns (` 11029/ha), and reduction in price of brinjal output (3%), etc. would be at 15 per cent adoption level.

Will Higher Shipping Costs Drive the U.S. to Source More Localized Produce?
Provedor de dados: 31
Autores: Woods,   Timothy A.; Saghaian,   Sayed H.; Ona,   Lucia Y.
The recent wide fluctuations in diesel fuel costs and subsequent trucking costs has raised speculation within the produce industry of potential structural shifts in the location of production.  Recent increases in demand for local produce seem to further support speculation toward this end.  A component pricing model is used to actually examine the impact of fuel prices on farm gate and retail produce prices for strawberries, lettuce, and potatoes.  The study finds that distribution costs, while significantly increasing in absolute value, have surprisingly little contribution to changes in retail prices even in markets distant to the primary production regions.  These results suggest that factors other than lower distribution costs for local produce will...

Biotechnology in Agriculture and Forestry: Economic Perspectives

Autores: van Kooten,   G. Cornelis.
Economists are rarely brought into the interdisciplinary research until the biophysical scientists have developed their models, made their measurements or completed their research task. The research economist is then brought in to do what amounts to a consulting task – provide some numbers that indicate impacts on the economy and employment. In this paper, I begin by illustrating cases from forestry where this leads to erroneous and costly policy outcomes. However, the main objective of this paper is to examine the role of genetic engineering in forestry and agriculture. In forestry, planting of genetically-modified (GM) tree species is nearly non-existent, with the exception of hybrid poplar that is used to produce pulp or fuel. However, as explored here,...

Interdependencies in the Energy-Bioenergy-Food Price Systems: A Cointegration Analysis
Provedor de dados: 31
Autores: Ciaian,   Pavel; Kancs,   d'Artis.
The present paper examines a long-run relationship between the energy, bioenergy and food prices. In the recent years the bioenergy production has increased significantly around the world. The increase has been driven by rising energy prices as well as by environmental policies aiming at reducing the harmful effects of conventional sources of energy, such as climate change. Bioenergy, in turn, affects agricultural markets, because it uses agricultural commodities as inputs. The theoretical model we develop predicts that, because of price inelastic food demand, the agricultural price increase may be substantial. The empirical findings confirm the theoretical hypothesis that energy prices do affect prices of agricultural commodities. However, the...

Price distortions on the Hungarian raw milk market
Provedor de dados: 31
Autores: Voneki,   Eva; Hockmann,   Heinrich.
The paper attempts to identify the impact of market power in the Hungarian milk chain. Since the conventional conjectural variation approach provides suspicious results the incentives to collude are discussed in an alternative framework. It is argued that the high degree of market transparency, the high frequency of interaction, the low number of large firms which could actually influence market prices, the threat of severe sanctions due to the under-utilization of processing capacities as well as opportunistic behavior make collusive behavior more likely than competitive behavior. The empirical evidence for the period 1998 to 2006 supports this view.

The paper focus on the time adjustment paths of the exchange rate and agricultural producer and industrial prices in response to unanticipated monetary shocks following model developed by Saghaian et al. (2002). We employ Johansen's cointegration test along with a vector error correction model to investigate whether agricultural producer prices overshoot in a transition economy. Results indicate that agricultural prices adjust faster than industrial prices to innovations in the money supply, affecting relative prices in the short run, but strict long-run money neutrality does not hold. The impulse response analysis shows that an exogenous shock to the money supply has a significant and volatile effect on the three price variables. Initially, both the...

Do U.S. Cotton Subsidies Affect Competing Exporters? An Analysis of Import Demand in China
Provedor de dados: 31
Autores: Muhammad,   Andrew; McPhail,   Lihong Lu; Kiawu,   James.
We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that developing countries are negatively affected by U.S. cotton subsidies, our focus is the price competition between the United States and competing exporters (Benin, Burkina Faso, Chad, Mali, India, and Uzbekistan). We further project how U.S. programs affect China’s imports by country. Results indicate that if U.S. subsidies make other exporting countries worse off, this effect is lessened when global prices respond accordingly. If subsidies are eliminated, China’s cotton imports may not fully recover from the temporary spike in global prices.

We demonstrate the use of the small-sample econometrics principles and strategies to come up with reliable yield and acreage models for policy analyses.  We focus on demonstrating the importance of proper representation of systematic and random components of the model for improving forecasting precision along with more reliable confidence intervals for the forecasts.  A probability distribution function modeling approach, which has been shown to provide more reliable confidence intervals for the dependent variable forecasts than the standard models that assume error term normality, is used to estimate cotton supply response in the Southeastern United States.

This study uses the sustainable growth rate model to investigate, measure, and analyze sustainable growth rates and trends for Illinois farmers. Results of farm-level econometric analyses indicate the relevance of the sustainable growth paradigm in explaining most farm financial decisions made each year. Grain farms have shown a greater tendency to balance growth through adjustments in production efficiencies while livestock farms rely more on financial leveraging strategies. In general, our results have shown that the farm sector has adapted to positive or negative sustainable growth challenges consistent with the Higgins' model and that, from an equilibrium point of view, countercyclical measures of the sustainable growth challenge indicate that there...

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.

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...

Recent literature about gravity models points out the importance of institutional frictions in the international market of agricultural products beyond the traditional economics variables as transport costs reducing the mass of trade in bilateral relationships. In particular, previous contributions stress that harmonization of food standards could decrease transaction costs in trading relationships by stimulating international market. In a previous work we hypothesized that the acknowledgment of equivalence in organic standards may represent a reliable signal of affinity in bilateral relationships which may be useful to identify areas in which transaction costs for both conventional and organic standards are lower.

Economic effects for three scenarios of antimicrobial drug use in livestock production -- a no-ban scenario and two levels of bans -- are examined through cost minimization and a partial equilibrium analysis.  Results indicate that regulating antimicrobial drug use in livestock production would increase per-unit costs of producers previously using drugs and reduce beef supplies in the short run, reducing consumer surplus.  Producers not previously using drugs would benefit from short-run price increases.

Trends, Determinants and Constraints of Temporary Sheep Migration in Rajasthan — An Economic Analysis
Provedor de dados: 31
Autores: Suresh,   A.; Gupta,   D.C.; Mann,   J.S.
The study has analysed the temporary migration of sheep as a response to the demand-supply disequilibrium of fodder and water and has explored its trends, determinants and constraints by using the data collected from rural areas of semi-arid Rajasthan. About 32 per cent of the farmers in the study area undertake temporary sheep migration. The migrating farmers have higher holding size of sheep, goat and buffaloes and are better in terms of adoption of improved sheep management practices than non-migrant farmers. The flock size, potential household labour supply and credit absorption behaviour have been reported to positively affect the odds of migration.

Assessment of the Impact of Avian Influenza Related Regulatory Policies on Poultry Meat Trade and Welfare
Provedor de dados: 31
Autores: Wieck,   Christine; Schlueter,   Simon W.; Britz,   Wolfgang.
We use two methodological approaches to analyze avian influenza related quarantine measures. First, a Heckman type gravity model is used to estimate the trade impact and second, a spatial partial equilibrium simulation model is developed to simulate welfare changes. The simulation model considers spread and transmission risk according to the disease status of the importing country as well as parameter uncertainty of the calibrated coefficients by using a Monte Carlo approach. The econometric results show that the principle of regionalization is preferred to import trade bans for uncooked meat. The simulation results verify the negative welfare impact of currently implemented regulatory policies and indicate that significant trade diversion effects...

An Analysis of Latin American Peanut Trade
Provedor de dados: 31
Autores: Lee,   Dae-Seob; Kennedy,   P. Lynn; Fletcher,   Stanley M.
The U.S. export share in the world peanut market has decreased due to heavy competition.  In this paper, the Latin American peanut industry is modeled using seemingly unrelated regression (SUR).  Based on these estimations, a scenario analysis was conducted.  The results show that the Latin American demand is not affected dramatically by either domestic of world price shocks.  The effects of price changes on net trade are noticeable.  However, the world price does not significantly affect the Latin American peanut supply.  The results imply that Latin American peanut farmers are more sensitive to changes in domestic prices than world price changes.

Border Effects on Spatial Price Transmission between Fresh Tomato Markets in Ghana and Burkina-Faso: Any Case for Promoting Trans-Border Trade in West Africa?
Provedor de dados: 31
Autores: Amikuzuno,   Joseph.
Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than overseas trade between SSA countries and the USA, EU and the BRIC countries. The difficulty of commodity arbitrage across international borders SSA is however a fundamental constraint to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade in Africa. This study examines the impact of border and distance on price transmission between tomato markets in Ghana and Burkina-Faso. The analysis applies a regime-switching vector error correction model to estimate semi-weekly, wholesale prices of tomato in four tomato markets in...

The Impacts of Animal Disease Crises on the Korean Meat Market
Provedor de dados: 31
Autores: Park,   Moon-Soo; Jin,   Yanhong H.; Bessler,   David A.
Employing the error correction method and historical decomposition with direct acyclic graphs, we quantify the impacts of domestic and oversea animal disease crises on the Korean meat markets. We find that (a) the market partially recovered 16 months after the foot-and-mouth outbreak in 2000, and 13 months after the avian influenza and the U.S. BSE incidents in 2003; (b) animal disease outbreaks have differentiate impacts by disease type and supply chain level. Retailers likely to have windfall profits as the retail price margin increased relative to the farm and wholesale levels; and (c) disease outbreaks affect dynamic price interdependence.

Taste Changes and Demographic in Spanish Seafood Consumption
Provedor de dados: 31
Autores: Millan,   Joaquin A.; Aldaz,   Natalia.
This study analyses seafood consumption at home in Spain using three different cross-sectional survey data-sets for 1980, 1990 and 1998.  Households are analysed in eleven different types, according to size and composition.  Price indices for seafood and meats are calculated for each household type.  Discrete participation and continuous consumption decisions are studied.  Socio-economic variables sometimes play an important role but not with a regular pattern.  Economic fundamentals follow a common pattern for all household types.  Seafood demand is inelastic in 1980 and very elastic and meat complement in 1990 and 1998.  Expenditure elasticity does not decrease between 1980 and 1998.

Perspectives d’évolution des marches céréaliers pour la campagne de commercialisation 2005/06

Autores: Diarra,   Salifou Bakary; Dembele,   Niama Nango.
The 2005 – 2006 marketing campaign was difficult because of the drought that occurred in all countries in the region. As a result, the price of sorghum, millet, maize and rice soared. State actions to improve cereals supply through tax-exempt rice imports did not achieve the expected outcomes. Rice has been the main contributing factor to the rise of cereals price. The low levels of stocks of rice in the world and the supply in fertilizers below expectations along with a decrease in productivity have contributed to the rise of rice prices at the national level.

ENSO AND SOYBEAN PRICES: CORRELATION WITHOUT CAUSALITY
Provedor de dados: 31
Autores: Letson,   David; McCullough,   B.D.
In this paper we seek to characterize the robustness of the ENSO/soybean price relationship and to determine whether it has practical economic content.  If such a meaningful relationship exists, the implications could be profound for commodity traders and for public sector investments in climate forecasting capabilities.  Also, the validity of economic evaluations of climate impacts and climate forecasts based on ENSO-price independence would come into question.  Our findings suggest a relationship between interannual climate and soybean prices, although we are not able to attribute the relationship to ENSO or to say the ENSO is economically important.

The Effect of Increased Energy Prices on Agriculture: A Differential Supply Approach
Provedor de dados: 31
Autores: Moss,   Charles B.; Livanis,   Grigorios T.; Schmitz,   Andrew.
The increase in energy prices between 2004 and 2007 has several potential consequences for aggregate agriculture in the U.S. We estimate the derived input demand elasticities for energy as well as capital, labor, and materials using the differential supply formulation. Given that the derived input demand for energy is inelastic, it is more price-responsive than the other inputs. The results also indicate that the U.S. aggregate agricultural supply function is responsive to energy prices.

Impact of Beef Quality on Market Signals Transmitted by Grid Pricing
Provedor de dados: 31
Autores: Johnson,   Heather C.; Ward,   Clement E.
Value-based marketing is shaping cattle production; however, market signals differ dramatically depending on carcass quality.  This study applies a two-stage coefficients of separate determination procedure to four regional fed cattle datasets sorted by grid value and by carcass quality attributes.  Weight is the strongest signal sent when higher valued cattle and better quality cattle are sold on a grid.  Quality characteristics send stronger signals when lower valued cattle and poorer quality cattle are sold on a grid.  Producers of lower quality cattle can potentially gain $52 to $149 per head by improving quality and $113 to $150 per head by adding weight.

We econometrically estimate consumer demand for dairy products in Japan using time series data for 1960-2003. We identify economic, cultural, and demographic forces that have been influencing dairy consumption patterns. We use the Almost Ideal (AI) Demand System by Deaton and Muellbauer and its variant, the Semiflexible Almost Ideal (SAI) Demand System developed by Moschini to impose concavity locally by reducing the rank of the Hessian of the expenditure function. We estimate three specifications: a full system comprising of four dairy products (fluid milk, powder milk, cheese, and butter), and an allother-goods aggregate; a subsystem for food made of four dairy goods and an all-other-food aggregate; and a sub-system of the four dairy products. The...

Drivers of Resident Support for Animal Care Oriented Ballot Initiatives
Provedor de dados: 31
Autores: Tonsor,   Glynn T.; Wolf,   Christopher A.
Recent high profile incidents and public debates in the United States have highlighted the increasing interest residents have regarding animal rearing and handling practices. This paper examines resident support for national legislation that mirrors Proposition 2, which in November 2008 passed in California. Results suggest perceptions regarding animal welfare information accuracy of livestock industry and consumer groups are particularly influential determinants of voting behavior and demand. The analysis also suggests residents may not fully appreciate price or tax implications when supporting additional animal welfare legislation. Implications for livestock industry and policy makers are provided along with suggestions for additional research.

Forecasting World Crop Yields as Probability Distributions
Provedor de dados: 31
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. To...

Autores: Scatasta,   Sara; Wesseler,   Justus; Hobbs,   Jill E.
This article contributes to the ongoing discussion about the impact of different labeling practices on the quality of genetically modified (GM) food products as perceived by the consumer. Thus far, many studies have adopted a stated preferences approach, finding that consumers have different willingness to pay for GM and non-GM products. This article offers an empirically tractable theoretical model that can be used easily to investigate the impact of GM labeling practices on the perceived quality of GM food products, making use of market data.

Organic Farming and the New CAP - Results for the Austrian Agricultural Sector
Provedor de dados: 31
Autores: Schmid,   Erwin; Sinabell,   Franz.
In 2003, the Common Agricultural Policy (CAP) has been reformed and decoupling direct payments from farm output is one of its core elements. We estimate the likely responses in organic product supply due to the reform at regional and sectoral levels. In addition, we analyse how the new programme for rural development, to be implemented in 2007, might affect organic farming. Our results show that organic farming will become more attractive after the 2003 CAP reform in Austria. Our results support the view that interactions among agri-environmental measures affect farmers' choice to maintain, abandon or adopt organic farming practices.

On the Theory and Practice of Water Regulation
Provedor de dados: 31
Autores: Tsur,   Yacov.
We study water regulation for a schematic water economy representing a wide range of real world situations. A water policy has inter- and intra-temporal components. The first determines the limits on extractions from the naturally replenished sources, given the stochastic nature of recharge processes associated with uncertain precipitation. The intra-temporal regulation is concerned mainly with the allocating of the extracted and produced water among the end-users. The prices that implement the optimal intra-temporal allocation are derived. Regulation issues associated with cost recovery and asymmetric information are discussed.

We assess market integration and price transmission of perishable agricultural produce in Sub-Saharan Africa by studying Ghanaian tomato markets which are characterized by pronounced seasonality in production and trade flows. We analyse the tomato markets of Ghana by simultaneously regarding its five most important markets, Navrongo, Techiman, Kumasi, Tamale and Accra, in a multivariate asymmetric price transmission framework. The estimation of the model is based on a unique dataset and on a modified version of the Johansen estimation procedure which is suitable for estimating such multivariate models. We estimate the price transmission parameters for four regimes which are a combination of the seasonal patterns in trade flows and asymmetries in the...

The Impact of Coordination of Production and Marketing Strategies on Price Behavior: Evidence from the Idaho Potato Industry
Provedor de dados: 31
Autores: Bolotova,   Yuliya; McIntosh,   Christopher S.; Muthusamy,   Kalamani; Patterson,   Paul E.
High potato price volatility, decreasing demand for fresh potatoes and prices below the cost of production led to a decision of a number of Idaho potato growers to organize the United Fresh Potato Growers of Idaho, a marketing cooperative. The programs and strategies of the cooperative target both the production and marketing of fresh potatoes in Idaho. To evaluate the effectiveness of the programs implemented by the cooperative, we examine the level and volatility of fresh potato prices during two periods: before the cooperative was organized and when the cooperative is in the market. We find empirical evidence suggesting that fresh potato prices were higher and less volatile during the period when the cooperative was in the market.

Autores: Muhammad,   Andrew.
Given the importance of EU demand for chilled fish fillets to the exporting sectors in Tanzania and Uganda, this study estimated the EU’s import demand for fillets by country of origin to assess the competitiveness of exporters. Results imply that prices in Tanzania and Uganda had an insignificant impact on total imports expenditures in the EU. Conditional and unconditional cross-price effects indicated that exports from Lake Victoria did not compete with exports from other suppliers, such as Iceland, Norway and ROW. Import demand forecasts showed that market share in the EU should remain relatively unchanged given the trend in prices.

Over the last few years, the production of renewable fuels has increased dramatically.  Rising oil prices, limited supplies of fossil fuel, and increased concerns about global warming have created a growing demand for renewable energy sources.  Both the ethanol and biodiesel industries have experienced tremendous growth in the past few years.  The production of these fuels is highly dependent on the availability of agricultural feedstocks.  This research examined the covariability between crude oil prices and corn, sorghum, sugar, soybeans, soybean oil, and palm oil prices during the 2003-2007 time period.  Johansen cointegration tests revealed no cointegrating relationships during the 2003-2005 time frame.  However, corn prices and soybean prices were...

Interactions between food demand, biomass energy and forest preservation are driving both food prices and land-use changes, regionally and globally. This study presents a new model called Nexus Land-Use which describes these interactions through a generic representation of agricultural intensification mechanisms. The Nexus Land-Use model equations combine biophysics and economics into a single coherent framework to calculate crop yields, food prices, and resulting pasture and cropland areas within 12 regions inter-connected with each other by international trade. The representation of cropland and livestock production systems in each region relies on three components: (i) a biomass production function derived from the crop yield response function to inputs...

This study examines the effect of banning antimicrobial growth promoters on efficiency in the production of weaned and slaughter (finishing) pigs. We focus on the reaction of producers and production efficiency. We evaluate the estimated output and input shadow prices relative to market prices to analyse producer reactions and capture the impact on production efficiency by evaluating the effects of the ban changes on total factor productivity. To this end we model a multi product shadow profit function and incorporate output and input related shadow prices by using a second order flexible functional form. The development in total factor productivity is subsequently measured by calculating the Malmquist index on the farm level. To make infer-ences on the...

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...

The government, through National Food Authority (NFA) has sought to establish stocks and control imports to stabilize prices since its establishment in 1972 to support farm gate prices and reduce retail price of rice. But data shows divergence in retail prices and farm prices since mid 1960s. In this paper, we use vector autoregression (VAR) to analyze the movement of Philippine rice margins with government stocks and weather supply shocks to able to determine government effectiveness in actual times of market stress. Comparing VARs across regions, we are able to identify the regions in which price margins are significantly...

LL601 Contamination and Its Impact on U.S. Rice Prices
Provedor de dados: 31
Autores: Li,   Yarui; Wailes,   Eric J.; McKenzie,   Andrew M.; Thomsen,   Michael R.
LL601 is a genetically modified rice variety and unapproved for commercial use. Its presence was found in commercial shipments of U.S. rice in 2006. This article explores its impact on prices and volume marketed for both the United States and Thailand, the major export competitor. The results show a significantly adverse but short duration effect on the U.S. rice market and little to no effect on the Thai rice market.

Analysing Wine Demand With Artificial Neural Networks
Provedor de dados: 31
Autores: Gerolimetto,   M.; Mauracher,   Christine; Procidano,   I.
In this paper we analyse wine demand in Italy using microdata. Instead of estimating a traditional parametric model (like AIDS) we employed artificial neural networks (ANN) and evaluate the elasticities using two different methods, specific for the non parametric framework. We compared the performances of the two methods to estimate elasticities and put in evidence the relevance of some demographic variables together with the usual economic ones, explaining the consumer's behaviour.

How Predictable are Prices of Agricultural Commodities? – The Possibilities and  Constraints of Forecasting Wheat Prices
Provedor de dados: 31
Autores: Holst,   Carsten.
Wheat price forecasts are very important for traders, farmers and politicians as well. However, only quite accurate price predictions can guide these groups towards making the best decisions. Therefore the well-known wheat price projections of both the OECD and the FAPRI from 1996 on are tested for their predictive accuracy using Theil’s inequality coefficient. Despite the fact that both models could not foresee the price peak which occurred in February 2008, their predictions offer more accurate values than a naive prediction of no price change. Nevertheless, precise price forecasts cannot be expected by the models of the OECD and the FAPRI since some short-run effects such as inappropriate weather are not predictable. Thus, our own econometric model is...

Unit Value Biases in Meat Demand in Indonesia
Provedor de dados: 31
Autores: Olivia,   Susan; Gibson,   John.
Indonesia is an emerging market for beef and cattle exports so estimates of income and price elasticities may help analysts predict future demands. In contrast to developed countries, where meat demand studies often use aggregate data, Indonesian studies rely on household surveys, with unit values (ratios of expenditures to quantities) used instead of market prices. Elasticities estimated from unit values can be subject to various quality and measurement error biases. In this paper, data from 29,000 households on Java are used to estimate a demand system for beef, chicken and other meat groups, and the extent of bias from commonly used estimation strategies is evaluated.

A Hedonic Metric Approach to Estimating the Demand for Differentiated Products: An Application to Retail Milk Demand
Provedor de dados: 31
Autores: Gulseven,   Osman; Wohlgenant,   Michael K.
This article introduces the Hedonic Metric (HM) approach as an original method to model the demand for differentiated products. Using this approach, initially we create an n-dimensional hedonic space based on the characteristic information available to consumers. Next, we allocate products into this space and estimate the elasticities using distances. What distinguishes our model from traditional demand models such as Almost Ideal Demand System (AIDS) and Rotterdam Model is the way we link elasticities with product characteristics. Moreover, our model significantly reduces the number of parameters to be estimated, thereby making it possible to estimate large number of differentiated products in a single demand system. We applied our model to estimate the...

The Impact of the E.coli Spinach Outbreak on Acreage Decisions Under Uncertainty
Provedor de dados: 31
Autores: Mohr,   Belinda Acuna.
This article quantifies the effect of the 2006 food-borne illness spinach outbreak on harvested acreage for the fresh spinach market.  In September 2006, fresh spinach contaminated with E. coli O157:H7 caused hundreds of consumer illnesses across the U.S. and a few deaths.  The outbreak was detrimental to the spinach industry causing a significant decrease in the demand for spinach.  Spinach growers were prohibited from harvesting spinach until more was known about the contamination.  According to the Census of Agriculture, harvested spinach acreage for the fresh market fell by 17% from before the outbreak.  Due to the unanticipated effects resulting from the outbreak, farms potentially decreased their acreage of fresh market spinach to reduce profit...

Rice Price Stabilization in Madagascar: Price and Welfare Implications of Variable Tariffs
Provedor de dados: 31
Autores: Dorosh,   Paul A.; Minten,   Bart.
Given the large share of major staples in the budgets of the poor, governments in many developing countries intervene in food markets to limit variation in the prices of staple foods. This paper examines the recent experience of Madagascar in stabilizing prices through international trade and the implications of adjustments in tariff rates. Using a partial equilibrium model, we quantify the overall costs and benefits of a change in import duties for various household groups, and compare this intervention to a policy of targeted food transfers or security stocks.

Grid Pricing: An Empirical Investigation of Market Signal Clarity
Provedor de dados: 31
Autores: Fausti,   Scott W.; Qasmi,   Bashir A.; Li,   Jing.
The ability of the grid marketing system for fed cattle to provide an efficient price transmission mechanism is investigated.  Nerlove’s (1958) adaptive expectations approach is adopted to model the relationship between grid premiums (discounts) and the weekly relative supply of carcass quality attributes. Linear regression techniques are used to estimate Nerlove’s supply response function. Granger Causality tests are conducted to investigate the relationship between grid premiums (discounts) and the relative supply of carcass quality attributes.  Regression estimates and the Granger Causality tests provide empirical support for the 2005 National Beef Quality Audit call for clearer market signals.

AN ASSESSMENT OF DYNAMIC BEHAVIOR IN THE U.S. CATFISH MARKET: AN APPLICATION OF THE GENERALIZED DYNAMIC ROTTERDAM MODEL
Provedor de dados: 31
Autores: Muhammad,   Andrew; Jones,   Keithly G.
Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed. Recently, Bushehri (2003) showed how a generalized dynamic Rotterdam model could be derived from the neoclassical intertemporal utility maximization problem; however, no empirical application is provided in his study. This paper provides an empirical application of the generalized dynamic Rotterdam model to the demand for processed catfish products in the U.S. The two-period dynamic Rotterdam model explained a significant amount of the variation in U.S. catfish demand and was preferred to the one-period and static...

Got (Safe) Milk? Chinese Consumers’ Valuation for Select Food Safety Attributes
Provedor de dados: 31
Autores: Ortega,   David L.; Wang,   H. Holly; Wu,   Laping; Bai,   Junfei; Olynk,   Nicole J.
Food safety issues often arise from problems of asymmetric information between consumers and suppliers of food with regards to product-specific attributes or characteristics. Food safety concerns in China are having a drastic impact on consumer behavior, commodity markets, international trade and food security. An additional challenge to the problem of asymmetric information lies in the inherent structure of the governing bodies which oversee food safety and quality. Unlike the United States and other developed countries, China’s food safety is regulated by several government entities with different and sometimes overlapping responsibilities. As a result consumers don’t have a comprehensive food safety and quality system on which to base their economic...

Does Price or Income Affect Organic Choice? Analysis of U.S. Fresh Produce Users
Provedor de dados: 31
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.

Returns in Commodities Futures Markets and Financial Speculation: A Multivariate GARCH Approach
Provedor de dados: 31
Autores: Manera,   Matteo; Nicolini,   Marcella; Vignati,   Ilaria.
This paper analyses futures prices for four energy commodities (light sweet crude oil, heating oil, gasoline and natural gas) and five agricultural commodities (corn, oats, soybean oil, soybeans and wheat), over the period 1986-2010. Using CCC and DCC multivariate GARCH models, we find that financial speculation is poorly significant in modelling returns in commodities futures while macroeconomic factors help explaining returns in commodities futures. Moreover, spillovers between commodities are present and the conditional correlations among commodities are high and time-varying.

Autores: Pan,   Suwen; Fang,   Cheng; Sanogo,   Issa; Mutuc,   Maria Erlinda M.
A comprehensive analysis of food demand and nutrient consumption using recent, representative household survey data from Malawi is presented. Expenditure and price elasticities have been estimated for 20 food groups using a quadratic almost ideal demand system based on 4 income groups identified by the Goldfeld-Quandt tests. Although the current boom of maize price provides an opportunity to rethink development strategies that diversify the commodity sectors, developing countries will not necessarily benefit from this change absent significant improvements in production capacities and trade infrastructures. Malawi is likely to suffer from higher commodity prices in the short-run.

Did the Fischler reform increase market integration between the EU and world commodity markets?
Provedor de dados: 31
Autores: Mela,   Giulio.
This work assesses the extent to which h the Fischler reform of the CAP increased the elasticity of price transmission (EPT) between the world and the European agricultural commodity markets. Commodities considered are soft and durum wheat, corn, feed barley, and butter. Results show that the reform increased ETP for all commodities even though with different magnitude. Before reform implementation (January 2007), the ETP was almost zero (meaning market isolation) for soft wheat, feed barley, and butter, while it was relatively low (0.4) for corn and durum. After January 2007, the EPT increased to almost unity (perfect transmission) for soft wheat and barley, to 0.9 and 0.8 for durum and corn, and to 0.5 for butter, which had historically been amongst the...

Optimal Seasonal Allocation of Generic Dairy Advertising Expenditures
Provedor de dados: 31
Autores: Schmit,   Todd M.; Kaiser,   Harry M.
Annual seasonal advertising expenditure allocations were estimated for the national generic advertising programs for fluid milk and cheese with the use of price and advertising elasticities of demand that varied over time.  Significant variation in optimal allocations existed both across products and over time, emphasizing the importance of obtaining accurate seasonal forecasts that incorporate changes in market conditions to plan future spending allocations.  In the absence of such information, allocating annual budgets equally across quarters still produced positive producer welfare gains on average relative to historical spending that were not statistically different from those realized under the optimal spending strategy.

The research analyzes the price transmission among the Costa Rican markets of cattle, beef and milk, accounting for asymmetric behavior and structural breaks. Monthly price data covering the first month of 1998 to the fourth month of 2008 were used. Price transmission between each market pair was found. The Price adjustment is consistent at 1% of significant with the behaviour expected. Cattle prices adjust in the milk - cattle relationship, beef meat prices adjust in the cattle - beef meat relation and in the milk - beef meat relation. This finding supports the statement regarding the leading position of “Dos Pinos” as the main player in the market. The results of the asymmetric analysis are not as expected.

How far do shocks move across borders? Examining volatility transmission in major agricultural futures markets
Provedor de dados: 31
Autores: Hernandez,   Manuel A.; Ibarra,   Raul; Trupkin,   Danilo R.
This paper examines the dynamics of volatility across major global exchanges for corn, wheat, and soybeans in the United States, Europe, and Asia. We follow a multivariate GARCH approach and account for the potential bias that may arise when considering exchanges with different closing times. The results indicate that agricultural markets are highly interrelated and there are both own- and cross-volatility spillovers and dependence among most of the exchanges. Chicago particularly plays a major role in terms of spillover effects over other markets. Additionally, the level of interdependence between exchanges has only increased in recent years for some commodities.

Understanding the Underlying Fundamentals of Ethanol Markets: Linkages between Energy and Agriculture

Autores: Tokgoz,   Simla; Elobeid,   Amani E.
This study analyzes the impact of price shocks in three input and output markets critical to ethanol: gasoline, corn, and sugar. We investigate the impact of these shocks on ethanol and related agricultural markets in the United States and Brazil. We find that the composition of a country's vehicle fleet determines the direction of the response of ethanol consumption to changes in the gasoline price. We also find that a change in feedstock costs affects the profitability of ethanol producers and the domestic ethanol price. In Brazil, where two commodities compete for sugarcane, changes in the sugar market affect the competing ethanol market.

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.

We analyze vertical price transmission in the German biodiesel market studying the relationship between rapeseed oil, soya oil and biodiesel prices. We focus on the period from summer 2002 to late 2007 during which the German biodiesel market developed into the largest market worldwide, mainly driven by political intervention. Tests on the adequacy of a traditional linear vector error correction model provide strong evidence against it and favor a regime-dependent model. We consider the Markov-switching vector error correction model which allows for parameter switching between regimes to be suitable for the question to be analyzed. We find two distinct regimes with differing error-correction behavior. Estimation results indicate that only rapeseed oil...

This study updates existing literature on consumer/household demand for fiber by examining household purchase dynamics for dietary fiber. It uses a dynamic Tobit model that allows past purchase occasions to affect current purchase decisions for fiber in a framework that captures simultaneously state dependence, unobserved households heterogeneity preferences, and serial correlation caused by a stationary first-order choice process. The model controls for the unobserved heterogeneity by adopting a Gaussian random effects specification. It also captures variations in prices over time and controls for left-censoring. The dynamic model is estimated using the Geweke-Hajivasssiliou-Keane recursive probability simulator and a unique dataset that contains detailed...

Autores: Sackett,   Hillary M.; Shupp,   Robert S.; Tonsor,   Glynn T.
This paper uses data collected in the summer and fall of 2010 from a national, web-based survey of 1002 households to initiate the process of examining consumer inferences and valuations of food products making "sustainably produced” claims. A Best-Worst scaling framework was implemented to identify what consumers believe “sustainably produced” labels mean and their preferences for each of the individual sustainable farming practices. The best-worst survey method forces respondents to make trade-offs by simultaneously choosing the most and least preferred attributes. The measured level of concern is then applied to a ratio scale. The ability of a firm to differentiate their product hinges critically on an accurate understanding of the perceptions consumers...

The Barakat Fruit Farm desires to increase their share of the exportable grape market in Egypt. Unfortunately, the grape cultivars currently cultivated by the farm bear fruit after the early market window to the European Union when prices are high. An analysis of the company, competition, consumer, market channel, and conditions, provides insight into possible solutions to the challenges faced by the farm management. Designed for undergraduate classroom use, this case encourages students to think outside of traditional production techniques to arrive at solutions that are viable from both crop culture and financial standpoints.

The Integration of Tomato Markets in Ghana with and without Direct Trade Flows
Provedor de dados: 31
Autores: Ihle,   Rico; Amikuzuno,   Joseph.
Spatial market equilibrium theory views trade flow as the driving force behind market integration. We assess spatial price transmission between domestic tomato markets in Ghana to ascertain whether spatial price transmission veritably depends on direct trade between markets, or whether other forces drive market integration. We analyze a unique data set on tomato trade consisting of semi-weekly price and trade flow data for the five most important Ghanaian markets for fresh tomato, which represents one of the most important commercially produced and consumed vegetables in the country. A regime-dependent vector error correction model is proposed to investigate this question, and the results are compared with those of a linear vector error correction model....

Will Changing Demographics Affect U.S. Cheese Demand?
Provedor de dados: 31
Autores: Davis,   Christopher G.; Blayney,   Donald P.; Dong,   Diansheng; Yen,   Steven T.; Johnson,   Rachel J.
U.S. cheese consumption has grown considerably over the last three decades. Using a censored demand model and Nielsen Homescan retail data, this study identifies price and non-price factors affecting the demand for differentiated cheese products. Own-price and expenditure elasticities for all of the cheese products are statistically significant and elastic. Results also reveal that a strong substitution relationship exists among all cheese products. Although demographic influences are generally smaller than those related to prices and expenditures, empirical findings show that household size, college educated female heads of household who are age 40 and older, residing in the South, Central, and Western regions of the United States, as well as Black heads...

Spatial Analysis of Factors Affecting Finnish Farmland Prices
Provedor de dados: 31
Autores: Pyykkonen,   Perttu.
The purpose of the study was to find out the factors affecting farmland prices in Finland. A hedonic pricing model that takes into account the presence of spatial dependence was applied for a very large sales price data (6 281 observations). The results confirmed the importance of land quality and the structural change as determinants of land price. In addition, off-farm job possibilities seemed to have a significant role in determining land prices. The effect of government payments on land prices was also clear, even though the support does not explain very much of the differences in land prices between regions.

Autores: Binfield,   Julian C.R.; Donnellan,   Trevor; Hanrahan,   Kevin F.; Westhoff,   Patrick C.
This paper uses a partial equilibrium commodity model of the EU agricultural market to examine the impact on the EU of two possible trade reform scenarios that could emerge under a World Trade Organisation (WTO) agreement. It explores the potential outcome up to 2017 under these scenarios, against a 2008 Baseline where trade policies are unchanged.  A particular feature of the paper is that it explores the issue of sensitive product designation in some detail. It demonstrates the complexity of the operation of tariffs and tariff rate quotas in key commodity markets and highlights how these complexities may produce different outcomes for particular commodity sectors.  It is found that sensitive product designation is of value to the EU beef sector in...

Perception of Land Scarcity by Peri-Urban Farmers
Provedor de dados: 31
Autores: Vandermeulen,   Valerie; Verspecht,   Ann; Van Huylenbroeck,   Guido.
Farmers in peri-urban regions face many problems, among which land scarcity is a major one according to literature. However, as indicated by a survey among farmers in the peri-urban region around Brussels, land scarcity is not perceived as a problem by all farmers to the same extent. Based on econometric analysis, the survey results show that perception of land scarcity is mainly influenced by differences in landownership and perceived ratio between farm land prices and real land prices. Changes in each of these variables will lead to a shift in the problems a farmer faces and will therefore stimulate different farming or land use strategies.

Regional Wholesale Price Relationships in the Presence of Counter-Seasonal Imports
Provedor de dados: 31
Autores: Raper,   Kellie Curry; Thornsbury,   Suzanne; Aguilar,   Cristobal.
Counter-seasonal imports of fresh produce facilitate year-round availability in the U.S. and may impact the seasonal structure of market price relationships. Vector autoregression analysis is used to determine the nature and extent of spatial price relationships among four geographically distinct regions in the U.S. fresh peach wholesale market. We evaluate differences in regional spatial price relationships and find statistical evidence that price relationships among regions are different in periods dominated by regional domestic supplies imports compared with periods when counter-seasonal imports dominate the market.

The economic competitiveness of biobased industries is discussed by comparing the South relative to other regions of the United States and biomass as a feedstock source relative to fossil fuels such as coal and petroleum.  An estimate of the biomass resource base is provided.  Estimated changes in the agricultural sector over time resulting from the development of a large-scale biobased industry are reported, and a study on the potential to produce electricity from biomass compared with coal in the southern United States is reviewed.  A biobased industry can increase net farm income and enhance economics development and job creation.

Autores: Parcell,   Joseph L.; Mintert,   James R.; Plain,   Ronald L.
An inverse live-hog model was estimated to analyze whether there has been a recent increase in the magnitude of live-hog, own-quantity demand flexibility.  Estimating the impact of processing capacity-utilization rate changes on live-hog prices was a second objective of this research.  Results indicate that live hog prices have become more responsive to changes in hog slaughter, slaughter weight, cold storage stocks, and changes in the processing capacity-utilization rate.  Finally, model results indicate that the sharp increase in processing capacity-utilization rates, the increase in average dressed weight, and the increase in hog slaughter all had a negative effect on the live-hog prices.

Estimation of a Censored Demand System in Stratified Sampling: An Analysis of Mexican Meat Demand at the Table Cut Level.
Provedor de dados: 31
Autores: Lopez,   Jose Antonio; Malaga,   Jaime E.
Evidence of meat trade in the form of table cuts suggests that consumer preferences and tastes vary across meat cuts. Unlike previous studies, this paper estimates demand elasticities at the table cut level from a Mexican survey of household incomes and expenditures, which is a stratified sample. The study uses the two-step estimation of a censored demand system proposed by Shonkwiler and Yen (1999) but incorporates stratification variables into the estimation procedure. Parameter estimates are reported and its standard errors are approximated by using the bootstrap procedure.

Provedor de dados: 31
Autores: Pendell,   Dustin L.; Leatherman,   John C.; Schroeder,   Ted C.; Alward,   Gregory S.
Contagious animal diseases like foot-and-mouth disease (FMD) are often referred to as economic diseases because of the magnitude of economic harm they can cause to producers and to local communities.  This study demonstrates the local economic impact of a FMD outbreak in southwest Kansas.  The expected economic impact of the disease hinges heavily on where the incidence of the disease occurs.  Disease surveillance, management strategies, mitigation investment, and overall diligence clearly need to be much greater in concentrated cattle feeding and processing areas at large feeding operations in the region.

Estimating Asymmetric Advertising Response: An Application to U.S. Nonalcoholic Beverage Demand
Provedor de dados: 31
Autores: Zheng,   Yuqing; Kaiser,   Harry M.
We propose a regime-switching model that allows demand to respond asymmetrically to upward and downward advertising changes. With the introduction of a smooth transition function, the model features smooth rather than abrupt parameter changes between regimes. We apply the model to nonalcoholic beverage data in the United States for 1974 through 2005 to investigate asymmetric advertising response. Results indicate that a decrease in milk advertising had a more profound impact on milk demand than an increase did. An increase in milk advertising had no impact on milk demand, but a decrease could have an own-advertising elasticity up to 0.049.

With this paper, we provide the first quantitative investigation of vertical price transmission in the biodiesel supply chain in Germany with the focus on the developments during the food crisis and the impact of subsidized US biodiesel exports. With the strong promotion of the production and use of biodiesel during the first half of the past decade, the German biodiesel market became the largest national biodiesel market worldwide. This analysis utilizes prices of rapeseed oil, soya oil, biodiesel and crude oil over a sample period covering the rapid growth of the German demand in 2002 until its decline in 2009. The effects of both the market development and different policies on price transmission are analyzed in detail. Due to the numerous changes in...

Variation in Staple Food Prices in Eastern and Southern Africa: A Synthesis
Provedor de dados: 31
The global food crisis of 2007-08 has focused attention on food prices, pushing the topic to the top of the agenda of international organizations. For policymakers in sub-Saharan Africa, however, food prices have been an issue of economic importance and political sensitivity for decades. Of particular importance are the prices of staple foods, defined as grains and starchy root crops that are inexpensive sources of calories. In eastern and southern Africa, maize is the most important staple food, followed by cassava, sorghum, teff, wheat, plantains, and sweet potatoes, with the importance of each varying by country. The importance of these staple foods cannot be underestimated, as they contribute 50-75% of the caloric intake of the population. Furthermore,...

Autores: Davis,   Christopher G.; Stefanova,   Stela; Hahn,   William F.; Yen,   Steven T.
In this study we estimated the price elasticities among meats, vegetables, grains, and potatoes and the impact that different levels of income have on the demand for these commodities.  The 2005 Nielsen retail home scan data were used to construct a censored demand system of 14 equations.   Results revealed that the uncompensated cross-price elasticities for both low and high-incomes suggest both substitution and complement relationships, while the compensated price elasticities are dominated primarily by substitution relationships.  Our findings also revealed that expenditure elasticities among both low and high-income households differ for most commodities.

Autores: Bakucs,   Lajos Zoltan; Ferto,   Imre.
The paper focus on the time adjustment paths of the exchange rate and prices in response to unanticipated monetary shocks following model developed by Saghaian et al. (2002). We employ Johansen's cointegration test along with a vector error correction model to investigate whether agricultural prices overshoot in a transition economy. The empirical results indicate that agricultural prices adjust faster than industrial prices to innovations in the money supply, affecting relative prices in the short run, but strict long-run money neutrality does not hold.

Modelling physical quantities of food and nutrients consumed from aggregate data – with an application to Finland
Provedor de dados: 31
Autores: Irz,   Xavier T.
Anticipating the impact of changes in economic incentives on dietary quality and nutritional health requires knowledge of how physical quantities of food consumed respond to price and income variations. A problem arises, however, because physical quantities are: 1- not consistent aggregates in demand models; and 2- not measured at final/retail level in national statistics. The paper develops a solution by establishing explicitly the theoretical link between composite demand and physical quantities, from which a novel empirical approach to the estimation of nutrient elasticities is derived. It is applied to Finnish aggregate data from the National Accounts and Food Balance Sheets over the 1975-2006 period, and the results are used to assess the potential...

Does Price Asymmetry Exist In Commodity and Energy Markets?
Provedor de dados: 31
Autores: Wixson,   Sarah E.; Katchova,   Ani L.
Recent increases in the price of crude oil have led to a rise in the prominence of corn-based ethanol as an alternative source of energy. As a result linkages have been established between commodity and energy prices. The aim of this study is to determine if soybeans, corn, wheat, oil, and ethanol adjust their prices asymmetrically depending on whether their actual price is over- or under-predicted with respect to one another. This study’s goal of determining if asymmetric price relationships exist is accomplished by using monthly time series price data incorporated into a distributed lag error correction model distinguishing between positive and negative price difference and positive and negative values of the error correction term.  The primary results...

Price discovery is a frequent topic of research, but many times is not clearly defined and thus purported to cover a myriad of topics.  This article provides two alternative theories as the basis for one line of price discovery research. Empirical models consistent with the two theories are estimated using a common data set.  Empirical results differ as expected.  This article evidences why the theoretical basis for an empirical model depends on clearly defining the objective(s) of the research.

Location and Spatial Pricing in Agricultural Markets
Provedor de dados: 31
Autores: Graubner,   Marten; Balmann,   Alfons; Sexton,   Richard J.
Agricultural markets often feature significant transport costs and spatially distributed production and processing which causes spatial imperfect competition. Spatial economics considers the firms’ decisions regarding location and spatial price strategy separately, usually on the demand side, and under restrictive assumptions. Therefore, alternative approaches are needed to explain, e.g., the location of new ethanol plants in the U.S. at peripheral as well as at central locations and the observation of different spatial price strategies in the market. We use an agent-based simulation model to analyze location and spatial pricing in a general model under multi-firm competition, two-dimensional space, and a continuum of potential price strategies.

Provedor de dados: 31
Autores: Costanigro,   Marco; Kroll,   Stephan; Thilmany,   Dawn D.; Nurse,   Gretchen.
Over the past two decades, consumer demand for niche products has grown substantially. The primary objective of this paper is to disentangle the value consumers place on two prominent food claims, organic and local (defined as Colorado Proud in this study) as they relate to fresh produce.  Using primary data from a choice experiment conducted in a grocery store that has conducted co-promotional efforts with the Colorado Proud program, we found the value of the “local” claims trumps that of “organic” in apples.   However, the difference in results between the experiments that offered participants either one- or two-pounds is far more pronounced, illustrating how scaling may influence estimates in such market-based research.

Market Power and Relative Price Adjustment: Evidence from the UK
Provedor de dados: 31
Autores: Morgan,   C. Wyn; McCorriston,   Steve.
Empirical studies of price transmission often suggest that imperfect pass-through may be due to market power exerted by food retailers. However, these econometric studies essentially lack any formal basis for tying the role of market power with data comprising of retail and producer prices only. We show that if market power has an effect on the farm-retail margin, this determines the specification of the cointegrating relationship. To emphasise the relevance of the tests, we focus on results relating the UK beef sector and show that market power is likely to have played a role in determining the retail-farm price margin.

What Drives Commodity Prices More: Oil Demand or Supply Shocks?
Provedor de dados: 31
Autores: Mutuc,   Maria Erlinda M.; Pan,   Suwen; Hudson,   Darren.
This paper shows that the response of agricultural commodity prices in the U.S. related to fluctuations in oil prices in the international market may differ greatly depending on whether the increase is driven by demand or supply shocks in the crude oil market. In the long-run, around 2-7 percent of the variability in grains, oilseeds, and cotton prices can be attributed to shocks to aggregate demand for industrial commodities while none can be traced to oil supply shocks.  This paper improves on the lack of economic structure in VAR models employed so far, and on the issue of short datasets, contributes to the nascent empirical evidence, and identifies the transmission of different types of oil price shocks to movements in agricultural prices in a SVAR...

A Case Study of Regulation in Zambia’s Cotton Sector.
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is an unquestioned success of Zambia’s turn towards a market economy. After privatization in late 1994, seed cotton production rose from 32,000 metric tons (mt) to about 180,000 mt a decade later (three-year averages centered on 1994 and 2005). The number of farmers involved in the sector grew similarly, yields trended upwards (though slowly), and the country dramatically improved the quality of its lint, becoming the outstanding performer  in Sub-Saharan Africa in this regard by the mid-2000s. Yet the sector has experienced two serious crashes since reform, both involving rampant credit default by farmers supported with seasonal input credit by ginning companies.

Autores: Ludena,   Carlos E.; Razo,   Carlos; Saucedo,   Alberto.
Rising oil prices has led to increased interest to replace domestic demand for liquid fuels for transport (petrol and diesel) with biofuel production (ethanol and biodiesel). One of the pioneers in biofuel production is Brazil, which since the 1970s has established a government program that promotes the production and consumption of ethanol. Currently, Brazil is the leading producer of ethanol in the world and has started also programs for biodiesel production based on soybeans, oil palm and other crops. Other countries in Latin America and the Caribbean have also expressed interest in biofuel production, and have started programs, and in some cases the legislation that promotes biofuel production. However, most of the analysis of biofuel crops has been...

The Influence of Macroeconomic Variables on the Hungarian Agriculture
Provedor de dados: 31
Autores: Bakucs,   Lajos Zoltan; Ferto,   Imre.
This paper focus on the time adjustment paths of the exchange rate and prices in response to unanticipated monetary shocks following model developed by Saghaian et al. (2002). We employ Johansen's cointegration test along with a vector error correction model to investigate whether agricultural prices overshoot in a transition economy. The empirical results indicate that agricultural prices adjust faster than industrial prices to innovations in the money supply, affecting relative prices in the short run, but strict long-run money neutrality does not hold.

CLIMATE CHANGE MITIGATION AND FUTURE FOOD CONSUMPTION PATTERNS
Provedor de dados: 31
Autores: Valin,   Hugo; Havlik,   Petr; Mosnier,   Aline; Obersteiner,   Michael.
Discussions on climate change increasingly emphasize the contribution of agricultural activities to anthropogenic greenhouse gases emissions. In this paper, we investigate from a supply to demand side perspective the stress between food demand and climate change challenges up until 2030. We examine how more stringent climate change mitigation policies could alter agricultural markets and put at risk the nutrition possibilities of populations. We use for this purpose GLOBIOM, an applied partial equilibrium model covering, at the world scale and a fine grid resolution, the main land-based sectors: agriculture, forestry and bioenergy. For this exercise, the model is fully linked to a semi-flexible endogenous demand system with non-linear Engel’s curves. Our...

Autores: Gerolimetto,   M.; Mauracher,   Christine; Procidano,   I.
In this paper, we present an analysis of farmed and wild fish in Italy using microdot.  Instead of estimating a traditional parametric model such as AIDS, we employ Artificial Neural Networks (ANNs) and evaluate elasticities using a method specific of the non-parametric framework.  As input variables, we consider not only the traditional economic factors but also some socio-demographic ones.

Modelling Organic Farming at Sector Level – An Application to the Reformed CAP in Austria
Provedor de dados: 31
Autores: Schmid,   Erwin; Sinabell,   Franz.
We analyse whether the 2003 CAP reform and the anticipated new program of rural development will lead to an expansion or a reduction of organic farming. An extended version of the Positive Mathematical Programming (PMP) method is developed in order to differentiate organic farming from conventional and other agri-environmental management practices in a sector model. Austria is chosen for the case study because 8 % of its farmland are managed organically, and detailed data on alternative management practices are available. The results suggest that the recent agricultural policy reforms will make organic farming more attractive for farmers, given the price premiums relative to conventional products will remain at observed levels.

Price Transmission throughout the U.S. Food Distribution System
Provedor de dados: 31
Autores: Kim,   Hyeyoung; Ward,   Ronald W.
Vertical markets for foods are linked through pricing systems with much of the performance seen through how well price information is reflected at points of exchange. Price linkage models are estimated using recursive asymmetric methods for measuring price linkages in the U.S. food distribution system for 100 food commodities from January 1995 to June 2009.  Preliminary results show that price linkages to be strong but declining over time with evidence of asymmetric in the long run.  Long run rising prices are pass through more than falling.

Dynamic Relationships Among U.S. Wheat-Related Markets: Applying Directed Acyclic Graphs to a Time Series Model
Provedor de dados: 31
Autores: Babula,   Ronald A.; Bessler,   David A.; Payne,   Warren S.
Using advanced methods of directed acyclic graphs with Bernanke structural vector autoregression models, this article extends recent econometric research on quarterly U.S. markets for wheat and wheat-based value-added products downstream. Analyses of impulse response simulations and forecast error variance decompositions provide updated estimates of market elasticity parameters that drive these markets, and updated policy-relevant information on how these quarterly markets run and dynamically interact. Results suggest that movements in wheat and downstream wheat-based markets strongly influence each other, although most of these effects occur at the longer-run horizons beyond a single crop cycle.

Autores: Dos Santos,   Alecsandro; Anderson,   John D.; Vann,   Rhonda C.; Willard,   Scott T.
Real-time ultrasound information taken on beef heifers prior to backgrounding is used to develop a logit model to aid heifer retention decisions. The value of ultrasound data is calculated as the difference in certainty equivalents between a decision rule incorporating ultrasound information and one using only visual cues. The value of ultrasound data is found to be around $10 per head but is influenced by heifer value and backgrounding costs.

Flower Power at the Dutch Flower Auctions? Application of an Inverse Almost Ideal Demand System
Provedor de dados: 31
Autores: Steen,   Marie.
Information on price-quantity relationships will enable flower producers to reduce risk and raise profits through better timing of rotations as well as better utilization of limited greenhouse space. The present paper presents econometric evidence on such price-quantity relationships for major species of cut flowers at the Dutch flower auctions. Specifically, an inverse linear approximate almost ideal demand model with seasonal adjustments is applied. This paper is introducing trigonometric functions as a flexible and inexpensive alternative that outperforms standard seasonal dummies. Major findings are that all flexibilities (quantity elasticities) are strongly significant. Own price flexibilities are negative as expected. The own flexibilities vary...

On the Theory and Practice of Water Regulation
Provedor de dados: 31
Autores: Tsur,   Yacov.
We study water regulation for a schematic water economy representing a wide range of real world situations. A water policy has inter- and intra-temporal components. The first determines the limits on extractions from the naturally replenished sources, given the stochastic nature of recharge processes associated with uncertain precipitation. The intra-temporal regulation is concerned mainly with the allocating of the extracted and produced water among the end-users. The prices that implement the optimal intra-temporal allocation are derived. Regulation issues associated with cost recovery and asymmetric information are discussed.

The ENSO Impact on Predicting World Cocoa Prices
Provedor de dados: 31
Autores: Ubilava,   David; Helmers,   Claes Gustav.
Cocoa beans are produced in equatorial and sub-equatorial regions of West Africa, Southeast Asia and South America. These are also the regions most affected by El Nino Southern Oscillation (ENSO) -- a climatic anomaly affecting temperature and precipitation in many parts of the world. Thus, ENSO, has a potential of affecting cocoa production and, subsequently, prices on the world market. This study investigates the benefits of using a measure of ENSO variable in world cocoa price forecasting through the application of a smooth transition autoregression (STAR) modeling framework to monthly data to examine potentially nonlinear dynamics of ENSO and cocoa prices. The results indicate that the nonlinear models appear to outperform linear models in terms of...

Using 1971-2000 data, we examine the accuracy of corn and soybean production forecasts provided by the USDA and two private agencies.  All agencies improved their forecasts as the harvest progressed, and forecast errors were highly correlated and unbiased.  The relative forecast accuracy of the agencies varied by crop and month.  For corn, USDA’s forecasts ranked as most accurate of the three agencies in all periods except for august during the recent period and improved most markedly as harvest progressed.  For soybeans, forecast errors were very similar, with the private agencies ranking as most accurate for August and September and making largest relative improvements for August during the recent period.  The USDA forecasts were dominant for October and...

This paper analyses the impact of food safety information about the “mad-cow” crisis on the demand for different types of fresh meat and fish in Spain. The theoretical model explicitly incorporates food safety information in the consumers’ utility function, from which demand equations are obtained. Two alternative functional forms have been considered, the standard AIDS and the Generalized Almost ideal Demand System (GAIDS) in order to overcome the problem of incorporating demand shifters in the traditional AIDS model. The food safety information has been incorporated into the demand function through a weighted information index built on the basis of the published news related to the mad-cow disease in the most popular Spanish newspaper. The comparison of...

The aim of this article is to investigate the relationship between Economic Value Added, traditional performance measures (Return on Assets ‘ROA’ and Return on Equity ‘ROE’) and their ability to measure the creation of shareholder wealth in food-processing firms in the Czech Republic. To assess the relationship, a simple regression test was used and the following hypothesis were tested: • a strong positive linear relationship exists between EVA and the traditional performance measures of ROA and ROE and • the EVA measure reflects changes in shareholder wealth more consistently than the traditional performance measures ROA and ROE. The regression analysis results indicate in all cases a positive correspondence between EVA and financial performance metrics...

DETERMINANTS OF THE DEMAND FOR ORGANIC AND CONVENTIONAL FRESH MILK IN GERMANY– AN ECONOMETRIC ANALYSIS
Provedor de dados: 31
Autores: Schrock,   Rebecca.
An increasing number of studies deals with consumer decisions regarding organic food, but only a few provide quantitative estimates of price and income elasticities. This paper contributes to the existing literature by providing own-price elasticity estimates as well as an analysis of the sociodemographic determinants of demand for organic milk. The analysis is based on the GfK Consumer Scan Scanner panel dataset on food purchases of German households covering a sample period of four years from 2004 to 2007. A two-step estimation procedure is applied. First, a probit regression examines which household characteristics affect the probability to buy organic milk. Second, a fixed-effects panel regression determines factors that have an impact on the quantity...

How did external pressures change Japan's protectionist farm policies from the Uruguay Round to TPP?: A Surplus Transformation Curve (STC) analysis
Provedor de dados: 31
Autores: Arahata,   Katsumi.
Japan’s seemingly monolithic protectionist farm policies were often easily moderated by external pressures. This study analyzes the change of the degree and the methods of protectionist farm policies, focusing on Japan’s most important crop, rice. It calculates consumer surplus, producer surplus and government spending in the past fifty years and integrates these figures into one diagram utilizing the STC (surplus transformation curve) analysis, developed by Bruce Gardner in 1983.     The result of the analyses suggests that external pressures have a considerable impact on domestic protectionist farm policies. For example, in 1986 when the demand by the RMA (Rice Milling Association) in the U.S. that Japan should open its rice market was issued, the STC...

Zusammenfassung: Die Wertschöpfungskette Milch in Deutschland steht vor der Herausforderung, sich in einem zunehmend liberalisierten Milch- und Milchproduktmarkt zu behaupten. Neben der Milchproduktion hat in der Wertschöpfungskette vor allem die Milchverarbeitung eine zentrale Funktion. Diese veredelt den international relativ homogenen Rohstoff Milch zu sehr unterschiedlichen Produkten. Die speziellen Produkteigenschaften von Milch (geringe Transportwürdigkeit und Lagerfähigkeit) erfordern zudem eine sehr enge Kopplung der beiden Wertschöpfungsstufen Milchproduktion und -verarbeitung. Dabei stehen sich in der Wertschöpfungskette viele Landwirte und einige Molkereien einem stark konzentrierten Lebensmitteleinzelhandel gegenüber. Die Molkereistruktur ist...

This paper aims to study how alternative trade policies will help mitigate the effects of climate change in agriculture in South Asia. We use a modified version of MIRAGE CGE for long term projections and allowing modeling of climate change effects (impact on yield) at a subregional level (163 geographical units at the world level) to simulate the effects of 13 SRES scenarios in 8 different trade policy landscapes. Based on these results, we discuss the ranking of trade policy options based on expected values but also in terms of variance using the theory of decision in uncertainty. Choices between unilateral and regional strategies for the countries of the sub regions are compared. Our results confirm that South Asia will be one of the most adversely...

The Impact of the Oil Sector on Commodity Prices: Correlation or Causation?
Provedor de dados: 31
Autores: Saghaian,   Sayed H.
The interconnections of agriculture and energy markets have increased through the rise in the new biofuel agribusinesses and the oil–ethanol–corn linkages. The question is whether these linkages have a causal structure by which oil prices affect commodity prices and through these links, instability is transferred from energy markets to already volatile agricultural markets. In this article, we present empirical results using contemporary time-series analysis and Granger causality supplemented by a directed graph theory modeling approach to identify the links and plausible contemporaneous causal structures among energy and commodity variables. The results show that although there is a strong correlation among oil and commodity prices, the evidence for a...

While agriculture definitely is a traditional and important sector of national economy, it is also a sector the importance of which is often underestimated. More correct and realistic description of its economic role should be based on input-output methods. Unfortunately regional level input-output tables are only rarely available. We therefore apply modified GRIT regionalization methodology on a remote rural NUTS 2 level region in three different countries (Germany, Greece, and the Czech Republic respectively) and demonstrate that this approach makes regional-level input-output analysis a viable tool in realistic evaluation of contribution of the agri-food production chain for local economies.

Autores: Ramirez,   Miguel A.; Wolf,   Christopher A.
Mexico is a major destination of dairy exports and is the single largest importer of US dairy exports. We use a restricted source almost ideal demand system to estimate the demand for dairy products imported into Mexico. The estimation facilitates an examination of the demand for dairy imports and the results have implications for exporting firms and countries. Our estimates indicate fierce competition for the Mexican market between the US, Oceania, and “other countries” primarily from South America.

Economic Hysteresis in Variety Selection
Provedor de dados: 31
Autores: Richards,   Timothy J.; Green,   Gareth P.
Investing in a new perennial crop variety involves an irreversible commitment of capital and generates an uncertain return stream.  As a result, the decision to adopt a new variety includes a significant real option value.  Waiting for returns to rise above this real option causes a delay in adoption because of economic hysteresis.  This study tests for hysteresis in the adoption of wine grape varieties using a sample of district-level data from the state of California.  The empirical results show a significant hysteretic effect in wine grape investment, which might be reduced by activities that smooth earnings over time.

Analysis of the potential to supply 25% of projected 2025 U.S. transportation fuels indicates sufficient biomass resources are available to meet increased demand while simultaneously meeting food, feed, and export needs. Corn and soybeans continue to be important feedstocks for ethanol and biodiesel production, but cellulose feedstocks (agricultural crop residues, energy crops such as switchgrass, and forestry residues) will play a major role. Farm income increases, mostly because of higher crop prices. Increased crop prices increase the cost of producing biofuels.

The Canadian chicken industry has operated under supply management since the mid-1970s. Canadian consumer preferences for chicken have grown dramatically since then possibly in response to concerns about health and the levels of fat and cholesterol in red meats. However Canadian consumers are also looking for convenience with their food purchases. Canadians are buying their chicken in frozen further processed forms, fresh by cut without skin and bone and in a variety of other different ways reflecting their unique willingness to pay for various attributes. There is also an increasing trend for retailers and processors to brand the fresh chicken product sold through grocery stores (for example, Maple Leaf Prime).

In the summer of 2008 the negotiations on the modalities for a new WTO agriculture agreement collapsed when seemingly on the verge of a successful conclusion. In this paper we present quantitative analysis of the impact of a new WTO agreement undertaken using a partial equilibrium model of Irish and EU agriculture. Results are presented on the agreement’s impact on Irish and EU-27 agriculture markets and on Irish agricultural sector incomes. Our analysis highlights the importance of the Baseline counter-factual, and will illustrate that protection afforded by the conferral of sensitive product status differs from commodity to commodity. The paper will draw conclusions concerning the economic...

Estimacion del valor del regadio a partir del precio de la tierra
Provedor de dados: 31
Autores: Sampedro,   Carlos Arias.
Este trabajo calcula el valor del regadío en la provincia de León a partir de datos de precios de la tierra desagregados por aprovechamiento y comarca. El valor de los beneficios asociados al regadío puede averiguarse comparando dos parcelas de tierra "iguales" excepto por el hecho de que una de las tierras sea de secano y la otra de regadío. La dificultad de encontrar estas parcelas de tierra iguales se soluciona acudiendo al análisis de regresión donde se analizan los efectos del regadío en el precio de la tierra tras controlar los efectos de las características que diferencian a las parcelas analizadas. Usando un modelo econométrico se calculan los precios medios de la tierra asociados a los aprovechamientos de secano y de regadío. La diferencia entre...

An Assessment of Dynamic Behavior in the U.S. Catfish Market: An Application of the Generalized Dynamic Rotterdam Model
Provedor de dados: 31
Autores: Muhammad,   Andrew; Jones,   Keithly G.
The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to fully adjust to changes in expenditures and prices. Additionally, habit persistence played a role in demand where present consumption of a given product was positively affected by past consumption of that product. Consequently, U.S. catfish demand was significantly more elastic in the long-run.

The Agricultural and the External (Net Barter) Terms of Trade in Bangladesh: Trends, Movements and Relationships, 1952-2006
Provedor de dados: 31
Autores: Hossain,   Akhand Akhtar.
This paper analyses the trends and movements of, and the relationship between, the agricultural and the external (net barter) terms of trade in Bangladesh for the period 1952-2006.  The Pesaran bounds testing results suggest the presence of a cointegral relationship between the agricultural and the external terms of trade in Bangladesh.  The forecasting ability of the error-correction model of the agricultural terms of trade is highly, satisfactory, irrespective of whether the level or the percentage change in the agricultural terms of trade is being forecasted.  The overall results suggest that the agricultural terms of trade in Bangladesh is determined endogenously and does not seem to have been deployed by policy makers to ‘squeeze agriculture’ within...

The Relative Impacts of U.S. Bio-Fuel Policies on Fuel-Energy Markets: A Comparative Static Analysis
Provedor de dados: 31
Autores: Kim,   C.S.; Schaible,   Glenn D.; Daberkow,   Stan G.
Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for blenders, refiners, and distillers, we conduct a comparative static analysis to measure the relative magnitudes of the impacts of tax credits and blending mandates on fuel-energy market equilibrium prices. Our results indicate that first, the prices of all fuels including conventional gasoline, ethanol, and blended gasoline decline as the biofuel tax credit increases, but they increase as the rate of the blending mandate increases. Second, the shadow value of a blending...

Volatility Spillovers between Food and Energy Markets, A Semiparametric Approach
Provedor de dados: 31
Autores: Serra,   Teresa.
Previous literature on volatility links between food and energy prices is scarce and mainly based on parametric approaches. We assess this issue by using a semiparametric GARCH model recently proposed by Long et al. (2009), which is essentially a nonparametric correction of the parametric conditional covariance function. We focus on price links between crude oil, ethanol and sugar prices in Brazil. Results suggest strong volatility links between the prices studied. They also suggest that parametric approximations of the conditional covariance matrix may lead to misleading results and can be improved using nonparametric techniques.

This working paper synthesizes the theoretical and empirical literature on the use of cash transfers in response to food crisis situations, with particular attention to their use in situations that are exacerbated by volatile, often inflationary, commodity prices. The paper is designed for policymakers who are wondering if cash transfers might be an appropriate instrument in the context of 2008’s unstable commodity prices for both food and energy, but are unfamiliar with the literature and discussions surrounding the cash vs. food debate. After defining some key terms and presenting a brief review of the theory behind cash transfer use, the paper synthesizes evidence from studies that have evaluated past cash transfer programs. While the focus is on...

Carcass Quality Volume and Grid Pricing: An Investigation of Cause and Effect
Provedor de dados: 31
Autores: Fausti,   Scott W.; Qasmi,   Bashir A.; Li,   Jing.
The relationship between publically reported weekly grid premiums and discounts for specific carcass characteristics and the percentage of those characteristics reflected in total weekly slaughter volume (i.e., proportional slaughter volume) is investigated.  Granger Causality and multi-lag VAR models were used to investigate if grid premiums and discounts were efficiently transmitting market signals to producers with respect to carcass quality attributes.  The empirical evidence indicates that there is little evidence to suggest that grid prices are providing efficient price signals to buyers and sellers with respect to market valuation of desirable and undesirable beef carcass characteristics.

Basis Volatilities of Corn and Soybean in Spatially Separated Markets: The Effect of Ethanol Demand
Provedor de dados: 31
Autores: Bekkerman,   Anton; Pelletier,   Denis.
The 2006 spike in corn-based ethanol demand has contributed to the increase in basis volatility in corn and soybean markets across the United States, which has, to a significant degree, led to the observed large jumps in the prices of the two commodities. Despite the overall rise in basis volatility, there remain differences in the degree of volatility that exists across spatially separated markets, which might be caused by factors such as transportation costs, seasonality, and time-to-delivery. The focus of this study is threefold first, this work models basis data for six corn and soybean markets by using a multivariate GARCH model that incorporates the spatial linkages of these markets; next, the model is used to investigate whether the increase in...

Discrete Choice Modeling of Consumer Preferences for Sustainably Produced Steak and Apples
Provedor de dados: 31
Autores: Sackett,   Hillary M.; Shupp,   Robert S.; Tonsor,   Glynn T.
"Sustainably produced" food labels have rapidly grown in popularity over the past decade (Batte 2011). Moreover, because there is no government agency overseeing certification of these production methods, consumers are generally confused about the production attributes that may or may not be present in a sustainable food system. This paper analyzes data from a hypothetical choice experiment to better understand consumer purchasing behavior when faced with competing food production attributes such as "organic" and "local". We seek to estimate preferences for "sustainably produced" food products and determine how they may be affected by varying degrees of information about sustainable agricultural systems. Additionally, the willingness to pay measurements...

Seasonal unit-root testing and seasonal cointegration methods are employed to investigate the price transmission in U.S. shrimp markets. ARIMA and Vector Error Correction Models (VECM) are used to identify the effect of catastrophic events on individual price series in one region and the spillover effects in the price series for other regions. Results showed that a cointegrating relation exists between neighboring states, specifically between Alabama and Mississippi and Louisiana and Texas. Cointegrating relations also exist between the Gulf States and the Pacific region, but not the Atlantic region, and the price of imported shrimp is cointegrated with each of the domestic shrimp price series. Finally, while Katrina had an effect on shrimp prices in Gulf...

The 2008/09 Food Price and Food Security Situation in Eastern and Southern Africa: Implications for Immediate and Longer Run Responses.
Provedor de dados: 31
Autores: Jayne,   Thomas S.; Chapoto,   Antony; Minde,   Isaac J.; Donovan,   Cynthia.
The dramatic rise in world food prices since 2007 has commanded the world’s attention. However, in recent months, world food prices have fallen almost as rapidly as they had risen in late 2007 and early 2008, yet as is demonstrated in this report, domestic food price levels in many eastern and southern African markets are not closely tracking world prices. Fertilizer prices remain at unprecedentedly high levels and may have a critical influence on future food production levels in the region. Against this backdrop, there is an urgent need for information about how the current food situation is unfolding in the region, the immediate policy response options, and the longer-term challenges and opportunities. This study has three objectives: 1) to examine the...

Context-Dependent BSE Impacts on Canadian Food-at-Home Beef Purchases
Provedor de dados: 31
Autores: Maynard,   Leigh J.; Wang,   Xin.
Household-level Canadian scanner data from 2002 – 2005 were used to identify consumer reactions to the early BSE discoveries that severely impacted Canada’s beef industry.  In all provinces, consumers reacted to the initial BSE event by purchasing more beef, apparently to support struggling ranchers.  Subsequent BSE events, however, met with reduced beef purchases.  The results were consistent across three measures of monthly beef purchases: participation, units purchased, and beef expenditure share.  Failing to account for the context of individual BSE events would have produced little evidence of consumer reaction, a common finding among prior North American BSE studies.

This study examines the time-varying Japanese price reactions to the 2001 Bovine Spongiform Encephalopathy (BSE) discovery, the 2000 outbreak of foot and mouth disease (FMD), and the 1996 E. coli food po isoning events. Historical decomposition of retail-level price-series aids in explaining the behavior of beef prices in a neighborhood (period-by-period time interval) of the three events. This is based on an application of directed acyclic graphs, constructing orthogonal innovations to determine causal patterns behind contemporaneous innovations. The results show the beef safety events had different negative impacts on Japanese retail beef prices, suggesting that consumers understood and differentiated among the health risks.

Impacts of Water Supply Changes on the Rice Market of Lao PDR: Stochastic Analysis of Supply and Demand Model
Provedor de dados: 31
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...

A mail survey was used to collect information about input procurement and ethanol and co-product marketing practices from 60 U.S. ethanol production facilities. Data were used to answer questions about the conduct or behavior of ethanol producers. It was anticipated that firm conduct or behavior would be fairly homogeneous because the ethanol industry was in Stage II of the industry life-cycle, and societal support for ethanol production resulted in large volumes of publicly available information about technology and markets. Age of facility, size of facility, and type of ownership jointly explained a limited number of differences in responses across ethanol facilities, thus supporting the concept of fairly homogeneous conduct or behavior.

An analysis of current and forecasted Mexican meat consumption and imports is presented at the table cut level of disaggregation. Unlike previous studies, this study uses adult equivalence scales, a price imputation approach, a consistent censored demand system, and estimation techniques from stratified sampling. The results indicate that most Mexican consumption and imports of table cuts of meats grow at different rates. In addition, Mexico seems to be following the U.S. preferences for beef cuts, but it does not seem to be following the U.S. preferences for chicken cuts. The study may help U.S. and Canadian meat exporters in forecasting future exports to Mexico, conducting long-term meat investment decisions, or identifying trends in the consumption of...

Pricing Options on Commodity Futures: The Role of Weather and Storage
Provedor de dados: 31
Autores: Bozic,   Marin; Fortenbery,   T. Randall.
Options on agricultural futures are popular financial instruments used for agricultural price risk management and to speculate on future price movements. Poor performance of Black’s classical option pricing model has stimulated many researchers to introduce pricing models that are more consistent with observed option premiums. However, most models are motivated solely from the standpoint of the time series properties of futures prices and need for improvements in forecasting and hedging performance. In this paper we propose a novel arbitrage pricing model motivated from the economic theory of optimal storage, and consistent with implications of plant physiology on the importance of weather stress. We introduce a pricing model for options on futures based...

Which factors drive which volatility in the grain sector?
Provedor de dados: 31
Autores: Ott,   Herve.
The present paper attempts to find empirical evidence on volatility in the grain sector (wheat, corn and soybean). The first challenge is to measure volatility. Intra-year volatility, inter-year volatility in level and return, also conditional volatility are defined and then calculated. The second challenge is to determine which factors impact volatility. The results show that depending on how volatility is measured, factors driving volatility are very different regarding their quantitative importance. Low stock to use ratio drives up mostly intra-year volatility but only moderately inter-year volatility and has almost no impact on conditional volatility. In contrast, a well functioning international market (trade flows without restriction) lowers...

Autores: Maynard,   Leigh J.; Saghaian,   Sayed H.; Nickoloff,   Megan.
Fish is a low-fat protein source high in omega-3 fatty acids, but in 2004 consumers also heard that farmed salmon had high levels of polychlorinated biphenyl (PCBs). This research evaluated how Canadian consumers and processors reacted to the conflicting health messages. Demand estimates and time-series analysis of 2001-2006 frozen meat scanner data in Alberta, Canada show a significant drop in salmon expenditure share following the PCB finding. The industry responded by launching low-priced wild salmon products, which contributed to significant demand expansion. The analysis illustrates how a food safety threat was averted and even served as a catalyst for growth.

The first, a large-scale partial equilibrium model, generated an outlook for maize grain under two possible future scenarios; the first is the baseline scenario under which it is assumed no additional government investment in the agricultural sector takes place, the second allows for the impact of an investment within the maize subsector large enough to increase local maize production by 15% above the baseline.  The second model, a rational distributed lag model, links the grain sector to the maize meal down-stream market....

Aggregation and Calibration of Agricultural Sector Models Through Crop Mix Restrictions and Marginal Profit Adjustments
Provedor de dados: 31
Autores: Wiborg,   Torben; McCarl,   Bruce A.; Rasmussen,   Svend; Schneider,   Uwe A.
All agricultural sector models must deal with aggregation and calibration somehow. The aggregation problem involves treating a group of producers as if they all responded in the same way as a single representative unit. The calibration problem concerns making a model reproduce as closely as possible an empirically observed set of decision maker actions. This paper shows how both calibration and aggregation are addressed through crop mix restrictions combined with marginal profit adjust-ments.

Slovak Agricultural Markets Under Alternative CAP Scenarios - AG-MEMOD Modelling Approach
Provedor de dados: 31
Autores: Pokrivcak,   Jan; Bartova,   Lubica; Ciaian,   Pavel.
Slovak sectoral partial equilibrium econometric model based on AG-MEMOD approach is used to analyse the development of the Slovak agricultural markets after EU accession. Simulation results for cereals, oilseeds and meats are provided in this article. Two scenarios are analysed: non-accession baseline and accession with adoption of single area payment scheme. EU accession is expected to increase prices of most products, the biggest increase of prices will occur in animal sector. Because of higher prices consumption will go down. Decrease of consumption will be mitigated by income growth. Production will not increase substantially due to decoupling of direct payments. Trade balance for majority of products will improve.

Spatial Analysis of Market Linkages in North Carolina Using Threshold Autoregression Models with Variable Transaction Costs
Provedor de dados: 31
Autores: Bekkerman,   Anton; Goodwin,   Barry K.; Piggott,   Nicholas E.
In North Carolina, where soybeans and corn are the two primary crops, the recent increase in the demand for U.S. corn has triggered a shift of farm acreage from soybeans to corn, leading to a rapid rise in prices of both commodities. However, the rate of the price changes, as well as the price level, is significantly different in markets that are located in different parts of the state.  This study extends the literature that examines linkages between spatially separated markets by using a threshold autoregressive model with a less restrictive assumption for estimating the transaction cost neutral band -- the band within which trade is not profitable. This generalization allows the neutral band of transactions costs to change according to various external...

Autores: Dong,   Fengxia; Du,   Xiaodong; Gould,   Brian W.
The classified pricing of fluid milk under the Federal Milk Marketing Orders (FMMO) system combined with the  cash settlement feature of Class IIII milk futures contracts generate a unique volatility pattern of these futures markets in the sense that  the volatility gradually decreases as the USDA price announcement dates approaching in the month.  Focusing on the evolution of volatility in Class III milk futures market, this study quantifies the relative importance of a set of factors driving milk price variation. While volatilities in both corn futures market and financial market Granger-cause the milk price volatility, the impact of financial market is more persistent. Besides embedded seasonality, market demand and supply conditions in the dairy...

The Economic Impacts of Avian Influenza on World Poultry Trade and the U.S. Poultry Industry: A Spatial Equilibrium Analysis
Provedor de dados: 31
Autores: Djunaidi,   Harjanto; Djunaidi,   Andrew C.M.
Simulation results showed that simultaneous outbreaks of highly pathogenic avian influenza (HPAI) in Asia, the United States, Brazil, and selected European countries will have significant impacts on world poultry trade. Assuming demand for chicken meat is constant, the global export price is simulated to increase by 9.63%. HPAI outbreaks in the United States, Economic Union, and Brazil will have a greater impact on export price than in any other possible three-region case. Outbreaks in the United States and Brazil would still lead to major impacts on world poultry trade, confirming large country effects.

Border Effects on Spatial Price Transmission between Fresh Tomato Markets in Ghana and Burkina-Faso: Any Case for Promoting Trans-border Trade in West Africa?
Provedor de dados: 31
Autores: Amikuzuno,   Joseph.
Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than trade between SSA countries and the USA or EU. The difficulty of commodity arbitrage across borders in SSA is however a fundamental impediment to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade. This study examines the impact of border and distance on price transmission between tomato in Ghana and Burkina-Faso. The analysis applies a linear and a regime-switching vector error correction model to estimate wholesale prices of tomato in four tomato markets in Ghana and a producer market in Burkina-Faso. The estimated...

Elasticities for U.S. Wheat Food Use by Class
Provedor de dados: 31
Autores: Marsh,   Thomas L.
We conceptualize wheat for food use as an input into flour production and derive demand functions to quantify price responsiveness and economic substitutability across wheat classes. Cost, 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. Morishima elasticities indicate that hard red winter and hard red spring wheat are economic substitutes for milling purposes.

Panel data from 14 EU member states and non parametric techniques are used in this paper to investigate the relationship between food prices and real per capita incomes. The empirical results suggest that the Penn Effect largely holds for Total Food prices but not for the prices of certain among the seven disaggregate food commodities considered. In particular, for Cereals, for Fats and Oils, and for Other food products poorer countries are likely to face prices no lower than those prevailing in richer ones

The relationship between trade and price volatility in the Mexican and US maize markets
Provedor de dados: 31
Autores: Araujo-Enciso,   Sergio Rene.
The supply of maize in the Mexican market depends to a large extent from the US imports which represent a large share of the domestic consumption. Furthermore imports exhibit a seasonal pattern, and peaks are often found close to low levels of domestic production and stocks. The present research suggests that there is a link between imports and prices volatility. Below a threshold value, imports and volatility are not related, but beyond the threshold it is volatility the variable driving imports. From the results one can argue that imports have served as a measure to stabilize prices when the domestic supply is scarce.

First, we review the development of the Japanese rice policy reforms since the Uruguay Round Agreement on Agriculture and the transition of the representative indices that measure the level of agricultural protection, such as the producer support estimate (PSE) and the aggregate measure of support (AMS). Next, a quantitative evaluation of the volume of transfers facilitated by the rice policies is carried out by employing the standard framework of welfare analysis. The changes in social welfare are simulated when the ex ante and ex post policies related to rice, namely, direct payment per output, purchase of rice by the government, and acreage control, are abolished and...

Assessing the Impact of International Natural Resource Management Research: The Case of Zero Tillage in India's Rice-Wheat Systems
Provedor de dados: 31
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...

Autores: Mutuc,   Maria Erlinda M.; Pan,   Suwen; Hudson,   Darren.
This paper shows that the response of cotton prices in the U.S. to fluctuations in oil prices in the international market may differ greatly depending on whether the increase is driven by demand or supply shocks in the crude oil market. In the long-run, around 3 percent of the variability in cotton prices can be attributed to shocks to global demand for industrial commodities while none can be traced to oil supply shocks.

Are Citizens Willing to Pay for Agricultural Multifunctionality?
Provedor de dados: 31
Autores: Kallas,   Zein; Gomez-Limon,   Jose Antonio; Arriaza Balmón,   Manuel.
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 cereal steppes in Tierra de Campos (Spain) as a case study. The economic valuation technique used is the Choice Experiment. The results suggest the existence of a significant demand for the different functions, although this demand is heterogeneous, depending on the socio-economic characteristics of the individuals.

Semiparametric Evidence on the Nature of Price Transmission in Tanzanian Maize Markets
Provedor de dados: 31
Autores: Ihle,   Rico; von Cramon-Taubadel,   Stephan.
Maize is a major staple food in Sub-Saharan Africa. Monthly maize prices in Tanzania are analyzed since the country is an important maize producer and exporter in East Africa. We analyze price transmission between the five most important urban regions of Tanzania between 2000 and 2008 which correspond to major maize production or consumption areas. We propose a novel method for the analysis. The semiparametric vector error-correction model allows the partial impact of the past deviations from price equilibria on current price changes to be potentially nonlinear. The nonparametric estimates of these partial influences suggest that they can be adequately modeled by linear functions.

This paper outlines a methodological approach for use by FAO to collect, analyze and monitor agricultural policy indicators (API) for developing countries. The aim is to establish a consistent and comparable set of policy indicators, allowing analysts to examine whether agriculture in particular countries is being stimulated or retarded by the set of policies employed. The API should also be useful in the context of quantitative models of policy impacts and market projections. Ideally, the indicators should function as building blocks for the more comprehensive policy measurement. This paper is presented in four parts. Part I gives an overview of the rationale for monitoring, the relationship between policy monitoring, quantitative modeling and evaluation,...

The 2005 – 2006 marketing campaign was difficult because of the drought that occurred in all countries in the region. As a result, the price of sorghum, millet, maize and rice soared. State actions to improve cereals supply through tax-exempt rice imports did not achieve the expected outcomes. Rice has been the main contributing factor to the rise of cereals price. The low levels of stocks of rice in the world and the supply in fertilizers below expectations along with a decrease in productivity have contributed to the rise of rice prices at the national level.

Based on a large-scale survey conducted in 11 large and small eastern cities in 2002, this study employs ordered probit models to estimate the effects of demographic and socio-economic variables on the likelihood of biotech food acceptance in China. This study also employs a dichotomous choice model to estimate consumers' mean willingness to pay (WTP) for biotech foods, including soybean oil and insect-resistant biotech rice. This survey reaffirms that Chinese urban consumers had a low awareness of biotechnology. Despite the low level of awareness, a great majority of respondents had favorable or neutral attitudes toward biotech foods. Only 5-15 percent was strongly or relatively opposed to biotech foods. Results from the models suggest that mid- and...

The ability of a firm to differentiate their product hinges critically on an accurate understanding of the perceptions consumers hold regarding the implications of a credence labeling claim. Building upon existing work evaluating other food attribute labels (e.g., genetically-modified products, region of origin, use of growth hormones) and the impact of consumer inferences (e.g., implicit associations made from explicitly provided information), this work begins to address gaps in the literature regarding food products with sustainably produced claims. This paper uses data collected in the summer and fall of 2010 from a national, web-based survey of 1002 households, to initiate the process of examining consumer inferences and valuations of food products...

Autores: Weingarten,   Peter; Frohberg,   Klaus; Winter,   Etti Maria; Schreiber,   Catrin.
Croatia recently signed several trade liberalisation agreements. The cornerstones of its trade policy are WTO membership, the Stabilisation and Association Agreement with the EU and Croatia's application of membership as well as bilateral free trade agreements within the Stability Pact for South Eastern Europe. The objective of this paper is to quantify the impact of Croatia's agricultural trade policy on the agri-food sector. For the analysis, a partial equilibrium model based on 1999/2000 data is used. Trade between Croatia and Bosnia and Herzegovina, Hungary, Slovenia, the EU-15 and the rest of the world is modelled for 12 product groups. Three liberalisation scenarios are analysed for the years 2002 and 2005. The scenarios differ with regard to the...

On the Evolving Relationship between Corn and Oil Prices
Provedor de dados: 31
Autores: Elmarzougui,   Eskandar; Larue,   Bruno.
The relationship between corn and oil prices is not a stable one. We identified three breaks in the relationship between corn and oil prices. The first break coincides with the second oil crisis. The second break marks the end of the agricultural export subsidy war between the EU and the US in the mid 1980s while the third one occurred at the beginning of the ethanol boom at the very end of the 1990s. The relationship between corn and oil prices tends to be stronger when oil prices are highly volatile and when agricultural policies create less distortion. The ethanol boom strengthened the relation between corn and oil prices which are (were not) cointegrated in the fourth regime (first three) regime(s). Impulse response functions confirm that corn prices...

Economic Evidence of Willingness to Pay for the National Animal Identification System in the US
Provedor de dados: 31
Autores: Resende Filho,   Moises de Andrade; Buhr,   Brian L.
This article investigates the willingness to pay for the National Animal Identification System (NAIS) in the US. It is assumed that with the NAIS in place, consumers' risk perception about zoonosis, BSE or mad cow and residues in meat may be mitigated. Therefore, food safety indices for beef, pork and poultry summing the number of references to meat safety found in the top fifty English language news articles in circulation in the US have been constructed. These indices were incorporated in generalized almost ideal demand systems to estimate the effect of those food safety scares on the demand for meat in the US. It has been found that food safety impacts upon the final demand for meat in the US are small and do not show lagged effects. Using the preferred...

Buyer and Seller Responses to an Adverse Food Safety Event: The Case of Frozen Salmon in Alberta
Provedor de dados: 31
Autores: Maynard,   Leigh J.; Saghaian,   Sayed H.; Nickoloff,   Megan.
Fish is a low-fat protein source high in omega-3 fatty acids, but in 2004 consumers also heard that farmed salmon had high levels of polychlorinated biphenyl (PCBs). This research evaluated how Canadian consumers and processors reacted to the conflicting health messages. Demand estimates and time-series analysis of 2001-2006 frozen meat scanner data in Alberta, Canada show a significant drop in salmon expenditure share following the PCB finding. The industry responded by launching low-priced wild salmon products, which contributed to significant demand expansion. The analysis illustrates how a food safety threat was averted and even served as a catalyst for growth.

Economic Impacts of Regionalization of a Highly Pathogenic Avian Influenza Outbreak in the United States
Provedor de dados: 31
Autores: Paarlberg,   Philip L.; Seitzinger,   Ann Hillberg; Lee,   John G.
This analysis examines the economic impact of an outbreak of highly pathogenic avian influenza (HPAI) and the consequences of regionalization. The results suggest that an outbreak would have serious economic effects. Depending on the regionalization scenario, returns to capital and management in the poultry meat and egg sectors would fall between $602 million and $853 million dollars over 16 quarters. Consumers of poultry meat lose $900 million in consumer surplus in the first four quarters, a decline of 10.7%. Egg consumer surplus falls 17.1%. Regionalization lowers the economic welfare losses for producers because it dampens the export loss.

Would Subsidizing a Food Pathogen Vaccine Upset the Food Policy Applecart
Provedor de dados: 31
Autores: Marette,   Stephan; Roe,   Brian E.; Teisl,   Mario F.
Vaccines against several common foodborne pathogens are being developed and could substantially alter the policy tools available to address foodborne illness.  However, little analysis is available to suggest how social welfare would be affected by these new vaccines.  To address this void, we use stated preference data to estimate consumer willingness to pay (WTP) for food safety vaccines and then simulate the welfare impacts on related commodity markets of subsidizing consumer purchases of the vaccine within a partial equilibrium framework.  To obtain consumer demand for the vaccine from the stated preference data, we simultaneously estimate model parameters in an econometrically coherent manner that recognizes the recursive nature of responses to...

ASSESSING KOSOVO'S HORTICULTURAL POTENTIAL - THE MARKET FOR FRUIT AND VEGETABLES ON THE BALKANS
Provedor de dados: 31
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...

The Value of Terroir: Hedonic Estimation of Vineyard Sale Prices
Provedor de dados: 31
Autores: Cross,   Robin M.; Plantinga,   Andrew J.; Stavins,   Robert N.
We examine the value of terroir, which refers to the special characteristics of a place that impart unique qualities to the wine produced. We do this by conducting a hedonic analysis of vineyard sales in the Willamette Valley of Oregon to ascertain whether site attributes, such as slope, aspect, elevation, and soil types, or designated appellations are more important determinants of price. We find that prices are strongly determined by sub-AVA appellation designations, but not by specific site attributes. These results indicate that the concept of terroir matters economically, although the reality of terroir – as proxied for by locational  attributes – is not significant.

Effects of Market and Policy Shocks on the Canadian and U.S. Cattle and Beef Industries
Provedor de dados: 31
Autores: Twine,   Edgar; Rude,   James.
The paper examines the impact of four exogenous shocks – exchange rate appreciation, feed price escalation, mandatory country of origin labeling, and economic recession – on the Canadian and U.S. beef cattle industries using a multi-market partial equilibrium model. Impacts on the U.S. industry are found to be relatively small compared to those on the Canadian industry. Country of origin labeling, and feed price escalation account for the largest decline in the welfare of Canadian cattle producers.

Ley de precio único en el mercado español del aceite de oliva
Provedor de dados: 31
Autores: Roldan Casas,   Jose Angel; Dios-Palomares,   Rafaela.
RESUMEN: El objetivo de este trabajo es el estudio de la integración del mercado español del aceite de oliva y la contrastación de la Ley de Precio Único (LPU) en dicho mercado. El análisis se lleva a cabo aplicando la técnica multivariante de cointegración a series mensuales (1987-2001) de precios de aceite de oliva correspondientes a las regiones en que el MAPA divide el mercado español peninsular. Los resultados muestran que los mercados españoles de aceite de oliva tienen un alto grado de integración siendo Noreste el mercado líder. No obstante, el mecanismo de transmisión de precios no es perfecto.

Estimation of Demand Elasticity for Food Commodities in India
Provedor de dados: 31
Autores: Kumar,   Praduman; Kumar,   Anjani; Parappurathu,   Shinoj; Raju,   S.S.
The food demand in India has been examined in the context of a structural shift in the dietary pattern of its population. The results have reinforced the hypothesis of a significant diversification in the dietary pattern of households in recent years and has found stark differences in the consumption pattern across different income quartiles. The food demand behaviour has been explained using a set of demand elasticities corresponding to major food commodities. The demand elasticities have been estimated using multi-stage budgeting with QUAIDS model and another alternative model, FCDS. The study has revealed that the estimated income elasticities vary across income classes and are lowest for cereals group and highest for horticultural and livestock...

Dynamics of Price Transmission in the Presence of a Major Food Safety Shock: Impact of H5N1 Avian Influenza on the Turkish Poultry Sector
Provedor de dados: 31
Autores: Saghaian,   Sayed H.; Ozertan,   Gokhan; Spaulding,   Aslihan D.
This article addresses the dynamic impact of the 2005 H5N1 avian influenza outbreak on the Turkish poultry sector. Contemporary time-series analyses with historical decomposition graphs are used to address differences in monthly price adjustments between market levels along the Turkish poultry supply channel. The empirical results show that price adjustments are asymmetric with respect to both speed and magnitude along the marketing channel. Results also reveal a differential impact of the exogenous shock on producers and retailers. The findings have critical efficiency and equity implications for the supply-chain participants.

EU-wide Distributional Effects of EU Direct Payments Harmonization analyzed with CAPRI
Provedor de dados: 31
Autores: Gocht,   Alexander; Britz,   Wolfgang; Ciaian,   Pavel; Gomez y Paloma,   Sergio.
We argue in this paper that available econometric estimates of farmers’ risk aversion do not measure true farmers’ preferences towards risky outcomes. Available analyses are mostly of static nature and indeed measure the parameters of the synthetic optimal value function rather than the deep parameters of the utility functions. We derive analytical and empirical results in a simple dynamic and stochastic framework showing that that there is not a simple relationship between utility functions and value functions when agents have many decision variables. In particular we find that the value function does not necessarily exhibit DARA when the instantaneous utility function satisfies DARA and conversely. We recommend performing dynamic econometric estimation...

Estimation of supply response in CAPRI
Provedor de dados: 31
Autores: Jansson,   Torbjorn.
The primary objective of this paper is to estimate behavioural parameters of the quadratic regional supply models in the modelling system CAPRI, using the time series data in the CAPRI database. A secondary objective is to replace the constant yields of the original model by functions that depend on input use. Due to lack of statistical robustness, the second objective is not achieved, thus yields remain constant. A Bayesian highest posterior density estimator is developed to address the primary objective. After discarding regions with insufficient data, parameters for up to 23 crop production activities with related inputs, outputs, prices and behavioural functions are estimated for 165 regions in EU-15. The results are systematically compared to the...

World Food Needs and the Optimal Allocations of Lands
Provedor de dados: 31
Autores: Hubert,   Marie-Helene; Moreaux,   Michel.
In order to assess the future world food demand/supply balance for the next century, in relation to the land uses, we develop a model in which the society has to supply two types of food demand, namely, processed crop products and meat and dairy products. From the supply side, the society can resort to different classes of land. Each class of land can be allocated wholly or partially either to crop cultivation or to pasture or last to be lain fallow. Primary crop production can be transformed either into processed crop products to satisfy final needs, or into intermediate livestock products used as inputs within the intensive industrial farming system. The livestock products can also be obtained from the extensive grazing system. The increase in world...
