An expected utility model that includes output price and yield uncertainly was used to estimate cotton, corn, and soybean acreage response equations for the Southeast. The model appeared to fit the soybean and corn data well, resulting in own-price elasticity estimates of 0.317 for com and 0.727 for soybeans. When applied to cotton acreage, however, the model did not yield satisfactory results. When elasticity was allowed to changeover time, however, statistical results for the cotton equation improved, yielding an own-price elasticity of 0.915 at data means.

A dynamic model is developed to analyze farmers’ irrigation investment and crop choice decisions under alternative water quality protection policies. The model is applied to an empirical example in the Oklahoma High Plains. The choices of crops and irrigation systems and the resulting levels of irrigation, income, and nitrogen runoff and percolation are simulated over a ten year period. An effluent tax on nitrogen runoff and percolation is shown to be effective in reducing nitrate pollution, The efficacy of cost sharing in adopting modern irrigation technologies and restrictions on irrigation water use depends on soil type. A tax on nitrogen use IS shown to be the least effective policy.

This study determines the likely effect of cost-share incentives on participation in the Tennessee Forest Stewardship Program and identifies other factors that may contribute to participation. A random utility model is used to determine the probability that a landowner will choose to participate in the program. A binary choice model is specified to represent the dichotomous decision and a logit procedure is used to tit the model. Data are obtained from mail surveys of 4,000 randomly selected landowners. Results indicate that attitudes and knowledge of forestry programs may be more influential in a landowner’s decision to participate than monetary incentives.

This article develops a conceptual framework for analyzing the role of state-level policies towards the dairy sector in the presence of farmland amenity benefits, and applies it to Connecticut. Milk supply, demand and amenity benefit functions are estimated, and three exogenously determined milk prices are considered. The empirical findings show, under each price scenario, the extent to which land is underallocated to the dairy sector if amenity benefits are ignored. Analysis of policy options reveals that a partial production cost subsidy represents the least-cost alternative for attaining the socially optimal solution for the region.

This study evaluates the attitudes of U.S. (Kansas) farmers regarding “free-trade”and “free-market”policy environments. In contrast to earlier studies, non-specific policy attitudes are evaluated. A direct measure of farm program benefits is also included. Attitudes vary significantly with farm and operator characteristics. Support for free trade was shown to decrease with education and experience, to increase for farms with relatively more rented land, and to increase as total farm wealth increased. Support for free-trade was also higher for crop farms. Farms receiving more government payments are less likely to favor a free-trade policy environment.

This study investigated the influence of economic, personal, and attitudinal factors on the Intended conservation effort of a sample of Conservation Reserve Program (CRP)contract holders after their contracts have expired. Economic factors were found to dominate the decision about future conservation effort. Attitudes towards conservation were found to have no significant influence on the decision. This fact may relate to the recent changes in the regulatory environment brought about by the 1985 Food Security Act which changed conservation from a voluntary to regulated nature.

The study examines Louisiana small fanners’ reasons for not participating in the Conservation Reserve Program {CRP), their awareness of the program. and their willingness to participate in the program. The results suggest that: farmers do not participate in the CRP if revenues from cropland are an important source of income, or if they are tenants; awareness is significantly related to education, income, race, and average return per acre; willingness is positively influenced by payment per acre, age, and farm status. Participation depends on whether payments per acre are comparable to the opportunity costs of removing cropland from production.

Key determinants of monthly wholesale prices for 12 beef cuts include the quantity of the specific cut, stickiness in prices, marketing costs, quantities of pork and chicken, and seasonality. Seasonal patterns across the respective cuts are very different. Relative to the price in December, prices at the wholesale level in other months can be as much as 6 percent lower to as much as 21 percent higher.

This paper identities optimal combinations of nitrogen in the form of urea, fresh litter and composted litter for rice production. Traditional cost minimization techniques using data from experimental results conducted at three sites in Arkansas during 1991 have been employed. Comparisons between different scenarios indicate that the trade-off between the use of poultry litter and urea nitrogen depends on such factors as soil fertility, the yield response to litter application and the relative prices of nitrogen and litter. The use of litter is more economical at high target yields than at low target yields.

This paper determines the effects of cattle feeders’ risk aversion on feeder cattle prices using pen data of Kansas feedlots. Higher profit risk results in lower feeder cattle prices. The elasticity of feeder cattle price with respect to profit risk was small (-0.013). The risk elasticity estimated here is similar to risk elasticities in previous studies and thus, the use of pen-level data does not seem to add much to the study of risk.

Mathematical programming results revealed that moving toward more flexible agricultural policies would generate substantial economic and environmental gains in a North Carolina diversified cropping region, But in a Washington-Idaho dry land grains region, only the use of relatively new and sometimes problematic alternative cropping systems permitted environmental and economic gains under policy reform. In both regions, a recoupling policy, which links government payments to resource-conserving farming practices, was needed to protect environmental quality when market prices for program crops were high.

A net trade model that includes environmental variables is used to analyze economic and environmental implications of various EC policies, There are environmental benefits from CAP reform, but a fertilizer tax results in greater nitrate and phosphate abatement. The input tax also results in smaller drops in EC farm income compared to CAP reform.

A structural probit model is estimated to determine the change in the probability of selecting a milk handler. Cooperatives are thought to have lower prices and higher deductions than independent milk handlers and these Factors reduce the probability that a farmer will select a cooperative by 0.39 and 0.32. Cooperatives are thought to have better services and an assured market and payment than independent milk handlers and these factors increase the probability that a farmer will select a cooperative by 0.20 and 0.26. This indicates that many cooperative members value monetary characteristics over non-monetary characteristics.

A multinominal logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production. Because of the industry’s geographic isolation and high turnover rate, data was collected by personal interviews in 1991. The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions. However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel.

Feedforward networks have powerful approximation capabilities without the “explosion of parameters” problem faced by Fourier and polynomial expansions. This paper first introduces feedforward networks and describes their approximation capabilities, then we address several practical issues faced by applications of feedforward networks. First, we demonstrate networks can provide a reasonable estimate of a Bermudagrass hay fertilizer response function with the relatively sparse data often available from experiments. Second, we demonstrate that the estimated network with a practical number of hidden units provides reasonable flexibility. Third, we show how one can constrain feedforward networks to satisfy a priori Information without losing their flexible functional form characteristic.
