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...

A 4-yr research and implementation project in Michigan apple production showed that deploying pheromone-mediated mating disruption for codling moth, Cydia pomonella L., in an areawide (AW-CMMD) program where mating disruption is established on all apple-producing acreage on individual and adjacent farms, significantly improves control of codling moth. The areawide project was compared with mati...

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...

The value of California citrus production in the 2020-21 marketing year was $3.63 billion. total economic impact industry on California’s economy $7.6 added $1.9 billion to state GDP 2020. Estimated full time equivalent jobs totaled 24,247. wages paid by income $759 million. A 20% reduction acreage would cause a loss 8,213 jobs, $214 million employee income, and reduce $569
