Introduction of biotechnologically modified soybeans will have significant impacts on the US soybean and associated industries. However, technical trade‐offs of yield and quality attributes make it difficult to determine which modifications offer the highest potential pay‐off and warrant the greatest emphasis in research, development, and, ultimately, market development. In this study, attention is focused on soybeans with modified protein and amino acid compositions where the primary end‐use is livestock feed. A generalized dynamic simulation model combining a linear programming model and an econometric model allows for market interactions between soybean and soy‐product industries, the livestock industry, and other closely related crop sectors. Results suggest all selected new soybeans promise significant welfare gains. © 1997 John Wiley & Sons, Inc.

An application of tests of economically rational behavior by fertilizer retailers is presented. Tests are developed to measure efficiency of variable cost minimization, revenue maximization, and profit maximization. These tests include standard linear programming‐based nonparametric efficiency tests and simpler but less conclusive tests which are performed using only simple arithmetic. Results indicate that fertilizer retailers act as variable cost minimizers, but not as revenue and profit maximizers. Additional tests isolate whether inefficiency in cost minimization is due to a perception of variable input fixity. Management can then take steps to focus efforts on input control. © 1997 John Wiley & Sons, Inc.
Who reacts to food safety scares?: Examining the Alar crisisHerrmann, Robert O.; Warland, Rex H.; Sterngold, Arthur

The 1989 Alar crisis developed in the wake of television news reports on the dangers to children from consuming apples treated with Alar. These hazards received extensive media coverage over the following five months. This study investigated public reaction to the crisis. Awareness of the crisis was more common among older adults, those with more formal education, and those who reported more frequent television news viewing. Those who were aware of the crisis and reduced their use of apples and apple products had a different set of characteristics. Reduced use was more common among females, those 50 and under, and non‐Whites. Reductions were not, however, more common among those who reported frequent television news viewing. © 1997 John Wiley & Sons, Inc.
Effects of air pollution abatement on financial performance of Texas cotton ginsFuller, S.; Gillis, M.; Parnell, C.; Ramaiyer, A.; Childers, R.

The Federal Clean Air Act (FCAA) amendments of 1990 strengthened air pollution regulation as it affects stationary sources such as cotton gins. The primary objective of this study is to determine likely success/failure rates for Texas gin plants that would result from introducing air pollution controls. Simulation analysis is carried out with firm financial models. The analysis projects many of the small and mid‐size gin plant firms that operate at relatively low volume levels to be financially unsuccessful ex ante investment in air pollution controls. As expected, the introduction of air pollution control lowers the likelihood of firm success, but, the unfavorable effect of these required investments is less pronounced among larger gin plant firms and plants that operate at high capacity levels. Results suggest the introduction of air pollution controls will accelerate the trend toward fewer and larger gin plant firms, and in order to survive, many Texas firms will find it necessary to merge/consolidate. © 1997 John Wiley & Sons, Inc.
