This paper contributes to an evaluation of the performance of ground nuts in drought-prone areas by estimating yield response functions to water from experimental data. They are combined with meteorological data to simulate yields by location. Efficient genotypes are identified by several risk...

In the drier areas of Syria yields of barley, the principal crop, are low. Due to the variability in rainfall, fertilizer use is perceived as risky. Barley-fertilizer trials have been conducted on farmer's fields over a period of four years to investigate whether the large yield response to...

The major sources of variability in net farm income on New York dairy farms over the past 10 years are identified using Dairy Farm Business Summary records. The most important source of income variability is the fluctuation in milk prices, followed closely by year-to-year variation in the...

A pollution reduction program is designed where information about both techno logy and risk preferences is asymmetric. Program costs and the distribution of payments depend on the amount of information known to the policy maker. Empirically testable conditions for selfselection are derived; the...

Major sources of variability in net farm income on New York dairy farms over the past 10 years are identified using variance decomposition methods. The most important source of income variability is the fluctuation in milk prices, followed closely by year-to-year variation in the quantity of...

This paper develops an incentive compatible policy to control agricultural pollution, where the government knows the ranges of technology types and risk attitudes but not their distributions across farmers. The policy creates incentives for farmers to participate in the program, but includes...

A model of a voluntary "green" payment program is developed to control nitrate leaching and runoff from corn production in New York. The program achieves environmental goals through self-interested choices of farmers, grouped by the productive and environmental characteristics of soils. It...
