Geographic concentration in US. hog production from 1974–96 is investigated using a measure based on Theil’s entropy index. For the U.S. as a whole, geographic concentration is occurring at a slow rate, both for hog farms and hog numbers. However, for particular states, primarily in the new Southern Atlantic production region, concentration is high and increasing at a rapid pace. Concentration was increasing for the 23-year period for 16 out of the 20 states in the analysis. Results indicate that geographic concentration by augmentation is occurring to the greatest degree in Arkansas, Missouri, North Carolina, Oklahoma, and Pennsylvania.
Incorporating the 1990 Farm Bill into Farm-Level Decision Models: An Application to Cotton Farms [статья]

A five-year, 0-1, mixed integer programming model was developed to analyze the effects of 1990 Farm Bill legislation on the crop-mix decisions made on cotton farms. Results showed that, when compared to the 1985 Farm Bill, the 1990 Farm Bill can result in higher whole-farm income despite new “triple base” provisions limiting payment acres. The increase in income results from elimination of limited cross-compliance provisions and the change to a three-year base calculation. The model was also used to assess the likely impact of possible changes in the current legislation.

A capitalization approach is used to estimate econometrically the effects of exchange rate, interest rate and tax law changes on thoroughbred yearling prices. The analysis found that exchange rate and tax law changes have significantly influenced yearling prices since the early 1980s. Another serious price-reducing event was the 1986 tax law change. Both of these factors have counteracted the positive impact of increased purse rates on yearling prices.

Rural-urban differences in the supply of nursing home services are hypothesized to be jointly affected by competitive and regulatory forces, government policies, and the cost structure. Study findings indicate that rural services are slightly less accessible and lower in quality. A translog cost share function reveals no difference in the operating cost structure of rural and urban homes. Cost shares for nursing care are directly related to the degree of skilled nursing provided by homes. Significant scale economies were not detected for any of the major operating costs.
