We use a regulatory model with resistance evolution in two pests to insecticidal Bt cotton and pyrethroids (a conventional insecticide) to examine non-Bt cotton (refuge) planting requirements designed to manage Bt-resistance evolution in the midsouth. Our analysis suggests that reduced refuge...

This article examines the potential demand for Bt cotton in the Southeast from information gathered in the first year of commercialization. We combine revealed preference (RP) data on adoption of Bt cotton varieties with stated preference (SP) data on willingness to adopt to estimate demand...

We use a random utility framework to examine within-season choices of insecticide products and application rates made by U.S. apple growers. Impacts on pesticide choices of insecticide efficacy, environmental safety, user safety, and regulatory attributes, as well as integrated pest management...

Agricultural commodities are typically produced over an extensive spatial area and are costly to transport relative to their total value. These characteristics yield a complex set of spatial price linkages which are often studied to gain insights into the performance of markets. An extensive...

Monitoring is an important and costly activity in resource management problems such as containing invasive species, protecting endangered species, preventing soil erosion, and regulating contracts for environmental services. Recent studies have viewed optimal monitoring as a Partially Observable...

Structural uncertainty arises when key features of the behavior of a system are not well understood. Observational uncertainty arises when key variables in a system are not directly observed. Both types of uncertainty lead to problems for standard dynamic optimization approaches. The replacement...
