Production Profitability of Ethanol from Alternative Feedstocks in the Texas Panhandle AgEcon
Almas, Lal K.; Lust, David G.; Brooks, Kathleen R.; Girase, J.R..
The potential of three feedstocks: grain sorghum, sweet sorghum, and switchgrass for ethanol production in the top 26 counties of the Texas Panhandle Region is analyzed using yield and production costs of feedstock, processing cost of feedstock, final demand for ethanol, farm to wholesale marketing margin, and the derived demand price of feedstock. The calculated economic returns per acre of grain sorghum, sweet sorghum, and switchgrass are -$45.37, -$410.19, and -$150.17 respectively under irrigated condition and -$38.25, -$145.09, and -$29.04 respectively under dryland condition. The evaluation in this study demonstrates that ethanol production from grain sorghum, sweet sorghum, and switchgrass in the Texas Panhandle Region is not economically...

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

The Choice of Technology in Russian Agriculture: An Application of the Induced Innovation Hypothesis AgEcon
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...

Technological Concentration of Innovation in Agribusiness AgEcon
Alfranca, Oscar.
The main objective of the paper is to examine and discuss the nature of technological relationships across agrifood sectors in order to understand better the pattern of technological changes in the Food and Beverage sector. We propose a new estimator to confirm the existence of linkages between technological sectors (the Technological Concentration Index). A central conclusion from this work is that the quality of data is a principal determinant in the measurement of technological flows, and that probably the use of raw patent data could introduce a distortion in the qualification of the consequences of technological spillovers.

Motivation for Technology Adoption and Its Impact on Abandonment: A Case Study of U.S. Cotton Farmers AgEcon
Uematsu, Hiroki; Mishra, Ashok K.; Roberts, Roland K.; Lambert, Dayton M.; English, Burton C..
We estimate a bivariate probit model with sample selection to identify factors affecting adoption and abandonment of precision farming technologies for cotton farmers, using the 2009 Southern Cotton Precision Farming Survey conducted in 12 Southern states in the United States. Farmers for whom being at the forefront of agricultural technology is not an important reason for adoption are more likely to abandon precision farming technologies. This study identified various factors associated with adoption and retention of precision farming technologies. Findings from this study offer significant information to policy‐makers for a better formulation of agri‐environmental programs that encourage farmers to adopt environmentally benign farming practices...

A Path Dependency and Cluster Competitiveness Framework to Examine Regional Marketing Systems and Conflicts AgEcon
Woods, Timothy A.; Cook, Roberta L..
This paper develops a framework for competitiveness that incorporates path dependency within production regions. Patterns of technological innovation, product development, institutions, and market orientation follow a certain local path. This evolution creates regional economies that emerge with unexpected competitive advantage. The model draws on previous work looking at, among other things, induced innovation. The framework is applied here to the major regional tomato producers in North America. The paper examines the role of various institutions (grower associations, governments, research institutions, and support industry) in influencing the path along which a regional sector evolves.

The Adoption of Best-Management Practices by Louisiana Dairy Producers AgEcon
Rahelizatovo, Noro C.; Gillespie, Jeffrey M..
This study examines the adoption of best-management practices (BMPs) in terms of the total number of practices implemented up to a certain period, using count data analysis. Poisson and negative binomial regressions were used to examine the likely determinants of producers’ decisions to adopt greater numbers of technologies, and the specific case of dairy producers’ adoption of BMPs was explored. Our results emphasize the significant effect of producers’ awareness of the efforts to control non-point source pollution, information about BMPs, farms size, producer’s educational attainment, and risk aversion on the number of BMPs adopted.

Potential Benefits of Bt Brinjal in India — An Economic Assessment AgEcon
Kumar, Sant; Lakshmi Prasanna, P.A.; Wankhade, Shwetal.
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. With increased adoption level of 60 per cent of Bt brinjal hybrids would provide, additional production of 119...

INTRODUCING NEW TECHNOLOGIES AND MARKETING STRATEGIES FOR HOUSEHOLDS WITH MALNUTRITION: AN ETHIOPIAN CASE STUDY AgEcon
Yigezu, Yigezu A.; Sanders, John H..
Many developing regions have excellent potential agricultural resources. However, historically population has become so concentrated on such small holdings that acute poverty and malnutrition now predominate. The food scientists’ response to the chronic nutritional problem has often been subsidized bio-fortification with nutritional supplements or more recently cultivars with higher nutrient levels. Where much of the population is in this inadequate nutrition category as in highland Ethiopia, the supplements are neither financially feasible nor sustainable. The cultivars can provide a few critical nutrients but are not a comprehensive solution. To improve nutrition, it is necessary to increase income so that an increased quality and quantitative diet can...

Analysis of Technical Efficiency and Varietal Differences in Pistachio Production in Iran Using a Meta-Frontier Analysis AgEcon
Boshrabadi, Hossain Mehrabi; Villano, Renato A.; Fleming, Euan M..
This paper reports on an analysis of technical efficiency and varietal differences in pistachio production in Iran. A random sample of 475 farmers was selected from the province of Kerman in 2003 and 2004. In this study, farmers are classified into three groups according to the variety of tree they planted. The three main varieties of pistachio trees planted are Kalleh- Ghuchi, Fandoghi and Akbari. The technical efficiency indices are computed using three approaches. First, a standard stochastic production frontier was employed using pooled data. Secondly, stochastic frontier production functions were estimated for each variety (separately). Lastly, the meta-frontier approach was used because production varieties and technologies are expected to differ...

Risk Management Education: An Examination of Crop Producers' Participation in Recent Programs and of Their Desire for Additional Training AgEcon
Knight, Thomas O.; Coble, Keith H.; Patrick, George F.; Baquet, Alan E..
Risk management education has been a focus of U.S. farm policy since 1996. In support of significant ongoing United States Department of Agriculture (USDA) educational efforts, this study examines agricultural producers’ educational needs and interests. Data obtained through a survey of crop producers are used in probit models examining interest in additional training in five areas including forward contracting, futures and options, crop yield insurance, crop revenue insurance, and financial management. The study results should be useful in determining appropriate risk management education program content and in indentifying and tailoring to specific target audiences.

Web Delivery of a Monte Carlo Simulation Model: The Base and Yield Analyzer Experience AgEcon
Richardson, James W.; Outlaw, Joe L..
The provision for producers to update base acres and payment yields in the 2002 farm bill afforded an opportunity to test whether it was feasible to deliver a complex simulation model directly to producers. A Monte Carlo simulation model for assessing the economic impacts of the alternative base and yield options on individual farms was developed and made available to producers via the World Wide Web. The experiences and challenges from this collaborative extension and research effort are described, as well as the issues educators might consider before delivering complex software to a national audience via the Web.

To Till or Not to Till? Social Profitability of No-Till Technology AgEcon
Lankoski, Jussi E.; Ollikainen, Markku; Uusitalo, Pekka.
We study from economic and environmental angles under what conditions no-till technology is socially optimal. We demonstrate theoretically that if yield under no-till is equal to or greater than under conventional technology, its adoption is socially optimal provided that herbicide runoff damages under both technologies are close enough. Finnish data shows, however, that only in one case out of three no-till provides higher social returns. In terms of nutrient runoffs no-till performs better than conventional technology. No-till reduces surface runoffs of nitrogen by 58%, and surface runoffs of particulate phosphorus by 70% relative to conventional technology, but causes more than three times higher dissolved phosphorus surface runoffs. The amount of total...

Transgenic Trees: Implementation and Outcomes of the Plant Protection Act AgEcon
Sedjo, Roger A..
The responsibility for protecting U.S. agriculture from pests and diseases is assigned by the Federal Plant Pest Act (FPPA) to the Animal and Plant Health Inspection Service (APHIS) of the Department of Agriculture. The Plant Protection Act (Title 7 U.S.C. Sections 7701 et seq.) gives Aphis statutory authority over genetically modified organisms (GMO), in effect assigning to APHIS a related responsibility of determining whether a genetically altered plant, crop, or tree is likely to pose unacceptable risks to the environment. Although APHIS has considerable experience with crop plants, it has only limited experience with trees. Yet the possible benefits of applying genetic engineering to trees are substantial and include industrial wood production and...

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

Should Europe Further Strengthen Intellectual Property for Plant Breeders? An Analysis of Seed Industry Proposals AgEcon
Eaton, Derek J.F.; van Tongeren, Frank W..
This paper illustrates the potential negative effects of increasing the scope of plant breeders' rights (PBR) protection, as has been proposed for Europe by leading plant breeding firms. Such a policy could increase the costs for varietal development for breeding companies, particularly if their access to varieties of the market leader is constrained. This is represented as an asymmetrical increase in breeders' cost functions in a simple model of endogenous quality choice under price competition. Increased scope of IPR protection leads to increased profits for the leading breeding company but decreases in varietal quality and both farm and overall profits.
