We develop a theoretical and empirical model to measure the benets and costs of policy options for controlling a seedborne, imported fungus, Verticillium dahliae, seriously aecting lettuce production in California. In 1995, the disease Verticillium wilt, caused by the fungus V. dahliae,...

This paper analyses the effects of the expiration of the volumetric ethanol subsidy and the implementation of the renewable fuels standard (RFS) on the U.S. fuel ethanol industry. Analyses that ignore the dynamic implications of these policies, including their effects on incumbent ethanol...

Tradeable credits are a central component of many market-based regulations. Whenever the market for compliance credits is efficient and policies are enforced over time, credit prices should reflect both current and expected future discounted marginal compliance costs, which are a function of...

This paper estimates a dynamic model of the world market for nine nonrenewable resources over the period 1970-2004, and tests whether the countries supplying a nonrenewable resource behaved as price-takers or oligopolists. The model generates estimates of the shadow price of the nine minerals...

Policies that encourage the use of more efficiency irrigation technology are often viewed as effective, politically feasible methods to reduce the consumptive use of water for agricultural production. Despite their widespread use, these policies have not been subject to empirical evaluation. In...

In a typical driving restriction, vehicle use is restricted based on the vehicle’s license plate; one cannot drive vehicles with certain license plate numbers on certain days. Driving restrictions have been used as a method to reduce urban air pollution or traffic congestion because they are...

Using Mexican survey data, a dynamic econometric model is estimated to test the effect of IRCA, NAFTA and border control expenditures on the flow of female and male migrant farm and non-farm labor from rural Mexico to the United States. We test for differential effects on male and female migration.

This paper evaluates the effects of annual fluctuations in temperature and precipitation on labor allocation in rural Mexico. We use a 28-year panel of individuals to investigate how people adjust their sector and location of work in response to year-to-year variation in weather. Controlling for...

The potential importance of natural resources in poor rural household livelihoods has long been recognized but seldom quantified and analyzed. In this paper we examine distributional and poverty effects of natural resource extraction. To do so we use new data from a national rural household...
