ESTIMATED RISK-RETURN COMPENSATIONS REQUIRED UNDER REDUCED NITROGEN USE AgEcon
Helmers, Glenn A.; Atwood, Joseph A..
An analysis was made of the reduced return and increased risk of reduced nitrogen use. The data source was an 11-year set of yields for continuous and rotational cropping of corn, soybeans, and grain sorghum each fertilized at three nitrogen levels. Risk was measured as returns below a target.

Risk-Efficient Fumigant-Mulching System Alternatives for Bell Pepper Production AgEcon
Ferrer, Myra Clarisse R.; Fonsah, Esendugue Greg; Escalante, Cesar L..
Tipo: Article Palavras-chave: As methyl bromide (MB) is phased-out for complete banning for agricultural use; This research evaluates the relative economic efficiency of fumigant alternatives; In combination with mulching methods. Bell pepper production in Georgia was studied in particular because any fumigant system that works for it would also work for other commercial crops. This study employs stochastic dominance techniques to identify the most efficient and preferred production alternatives in terms of gross and net enterprise returns. Based on risk efficiency; Mean returns and the decision-maker’s risk aversion considerations; This analysis identified TELV-MS; TEL-MS; And PC250-MS as the most preferred and risk-efficient alternatives.; Crop Production/Industries.

HIV/AIDS and Agrarian Livelihoods in Zambia: A Test of the New Variant Famine Hypothesis AgEcon
Mason, Nicole M.; Chapoto, Antony; Jayne, Thomas S.; Myers, Robert J..
Since the southern African food crisis of 2001/02, the ‘new-variant famine’ (NVF) hypothesis first proposed by de Waal and Whiteside (2003) has become an important part of the conventional wisdom surrounding the relationship between HIV/AIDS and food crises in the region. The NVF hypothesis suggests that HIV/AIDS is eroding agrarian livelihoods and exacerbating the effects of drought and other shocks on agrarian communities. These concepts have begun to shape the HIV/AIDS mitigation and food security policies and programs of governments and development agencies. To date, however, there is a dearth of empirical evidence to support the NVF hypothesis, and there have been no studies specifically designed to tests its predictions.

ESTIMATING CROP-SPECIFIC PRODUCTION GROWTH AND SOURCES IN CHINA AgEcon
Fang, Cheng; Fan, Shenggen.
This study uses aggregated provincial level data from 1979 to 2000 to estimate crop-specific production functions and identifies the sources of production growth for wheat, corn, soybean, rapeseeds, and cotton in China. The results show that fertilizer, pesticide, seeds, production specification, weather, and R&D are important determinants of crop yields. The land, fertilizer, and R&D are major contributors to production growth during the study period.

Welfare Impacts of the Mexico Potato Quarantine AgEcon
Richards, Timothy J.; Molina, Ignacio; Hussein, Osman.
Under the North American Free Trade Agreement (NAFTA) tariffs on U.S. potato imports to Mexico were phased out by 1993. Citing phytosanitary issues, in 1996, the Mexican government placed quantitative restrictions on U.S. potato imports and restricted their import only to designated border areas. This article estimates the welfare cost of restricting U.S. potato imports into Mexico. We find that removing trade restrictions may lead to over 1.8 million tons of new imports into Mexico, a gain of consumer surplus of 4.0 billion pesos per year, and a loss of 2.9 billion pesos of producer surplus.

U.S. WHEAT STORAGE CONTROL UNDER JOINT CRITERIA OF MEAN BENEFITS AND PRICE VARIATION AgEcon
Koo, Won W.; Burt, Oscar R..
A method based on stochastic dynamic programming is developed to derive efficiency frontiers for the trade-off between the long-run average social benefits and price variation. The method is used to quantify the importance of price variation per se as a criterion in U.S. wheat storage policy. The results suggest that a single criterion of maximum expected social benefits, calculated by the traditional surplus measures, is satisfactory because price variation is incidentally reduced enough that further reductions can be attained only a considerable opportunity cost.

A Binary Logit Analysis of Factors Impacting Adoption of Genetically Modified Cotton AgEcon
Banerjee, Swagata (Ban); Martin, Steven W..
Agricultural Resource Management Survey (ARMS) data for 2003 were used to estimate two binary logit models for two definitions of genetically modified (GM) cottonseed adoption. Results indicate conservation tillage did not positively affect adoption of GM cotton with either of these definitions, while adoption of GM cotton in the previous year did. Refuge cotton also did not affect these adoption decisions for the study year.
Tipo: Conference Paper or Presentation Palavras-chave: Agricultural Resource Management Survey (ARMS); Binary logit model; Conservation tillage; Cotton; Genetically modified seed; Herbicide-resistant cotton; Jackknife procedure; Refuge cotton; Stacked-gene cotton; Technology adoption; Crop Production/Industries.

PROTEIN DEMAND IN HARD WHEATS AgEcon
Wilson, William W.; Wilson, Wesley W.; Dahl, Bruce L..
Wheat protein is one of the most important specifications used in domestic and import purchase contracts. It is used as a proxy for functional quality that is important in domestic markets and to importers. Large differences exist in functional characteristics amongst wheat that vary by protein level and class. The purpose of this paper is to analyze the demand for wheat protein across importing countries and through time. A choice based econometric model is specified and estimated using a pooled data set of wheat shipments. Results indicate that there have been shifts over time, purchase probabilities are highly price elastic and vary across importing regions. In addition, income, traded goods, urbanization, females in the work force, and domestic...
