Beans are the most important relish crop in the farming systems of Serenje District in Central Province, Zambia. Both leaves and dried beans are major food sources for home consumption, and dried beans have a commercial value in the system. Given this dual role, increasing bean yields would...

This paper uses farm-level data collected from a sample of 500 households in Hunan province, China, to analyze the impact of hybrid rice on input demand and productivity. Based on regression analyses, it is found that, compared with conventional modern varieties, hybrid rice uses about 4% less...

Agricultural production is risky. When farmers are risk-averse, they are likely to put a premium on production methods that reduce perceived risks. Irrigation is generally believed to be a riskreducing input. By using the concept of stochastic dominance, risk-efficient irrigation policies for...

With a multi-market model of the U.S. tobacco and cigarette industries, we analyze the impact of a reduction in the assistance to U.S. tobacco producers by relaxing production quotas with nonbinding price support and by lowering tariffs on tobacco imports. The results show the importance of...

This paper reports the results of a study of the effects of the Indian government's consumer subsidies on wheat demand. Results indicate consumption of subsidized wheat is higher in urban areas than in rural areas. The public distribution of wheat in most states had little effect on demand in...

In this paper, the estimation of production functions and measurement of the rate of technical change is performed when selectivity bias is expected, A sample selection model consisting of a selection and a regression equation is estimated using Heckman's two-stage method. It is discussed in the...

This paper compares three models of input allocation in multicrop systems. In addition to the variable input and satisficing models analyzed in previous research, an allocatable fixed input model of short-run input use is derived. The empirical application studies irrigation water use in the...

Equity and efficiency considerations in area versus individual crop insurance are investigated for 609 Ontario cash crop farms. Results show that the relationship between individual and area premiums and risk reduction are explained by systematic and non-systematic yield risk relationships. On...
