considering the importance of increase in production and supply of agricultural products in iranian economic development, this study was carried out to investigate the impact of factors influencing the acreage (as a proxy for planned production and supply) of five important crops , namely wheat, barley, potatoes, sunflower and cotton. the seemingly unrelated regression estimation (sure) was use...

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 ...

We investigated the association between rice burning and daily asthma hospitalizations in Butte County, California, from 1983 to 1992. Eighty-two percent of planted rice was burned, with a mean of 555 acres burned on days when burning was permitted. For 60% of the days during this period, no rice burning occurred. Peak burning occurred in fall and spring but was not correlated with criteria pol...

A method is developed to estimate jointly risk preferences and technology under general conditions. The approach is illustrated in an application to the analysis of U.S. corn-soybean acreage decisions over time. The results provide useful information on the nature of farmers' risk preferences and on the influence of price risk and production risk on acreage allocation and fanners' welfare.

National survey data collected for 1997 in USDA’s Agricultural Resource Management Study was used to derive implications and pose hypotheses about the impact on pesticide use, production practices, and producer costs of using genetically modified (GM) seed in soybean and cotton production. Results of the analysis suggest concurrence with scientific and industry claims about the environmental qu...

The geographic concentration of production of main field crops in several growing regions is a distinctive feature of U.S. agriculture. Among many possible reasons for spatial concentration, I study here the effects of the distribution of end users and terminal markets on acreage allocation. The presence of multiple terminal markets in a growing area may allow for a more flexible marketing plan...

This article analyzes the dynamic effects of the farm subsidies in the United States. The subsidies a farmer receives are based upon historical plantings, also called base acreage. It is sometimes optimal for a farmer temporarily not to participate in a program in order to increase future subsidies. The farmer's optimal policy is the solution to a deterministic dynamic program. Farmers with low...
