Many argued during the NAFTA debate that trade liberalization would favor Mexican over U.S. food processors, especially because of lax environmental laws south of the border. We find through an examination of profit functions that productivity growth in Mexico has outstripped that in the United States, suggesting free trade indeed will benefit Mexican suppliers. U.S. pollution regulations have had no impact on the profitability or productivity of U.S. food manufacturing. In contrast, Mexico's swiftly rising environmental standards have enhanced food processors' productivity growth, corroborating the Porter hypothesis. Pollution law, therefore, has favored Mexican over U.S. food processing, but for reasons few had anticipated. Copyright 2002, Oxford University Press.

Applied studies of the firm in a risky environment have concentrated either on the firm's technology or on its risk preferences. These models result in generally inconsistent and inefficient parameter estimates. A primal model is proposed which allows a firm's preferences and technology to be estimated jointly in the presence of risk. The model is applied to Iowa corn production and estimated technology parameters are compared with those from other approaches. Modest risk aversion leads to inelastic (even backbending) per‐acre supplies and input demands. Yield heteroskedasticity in inputs leads to supply heteroskedasticity in prices, especially for risk‐neutral firms.

A supply and demand model of the Israeli hotel industry is developed, distinguishing between its domestic and foreign sectors. Model simulations are employed to examine the impacts of war and terrorist incidents on tourist activity and hotel revenues. Foreign demand for Israeli hotel stays is highly price-elastic and income-inelastic, and moderately sensitive to terrorist events. Domestic demand is price-inelastic, income-elastic, and terror-insensitive. In the wake of terror attacks, hotels' supply or minimum prices to Israeli tourists shift downward, reducing local market prices and encouraging more local tourism. However, the magnitude of these shifts is minor, and the local market thus provides little buffer for dropoffs in foreign tourism. By permitting excess capacity in such fashion, hotels respond rationally to the price inelasticity of local demand.
