This study investigates worker shares of the returns to scale and returns to technology adoption on U.S. hog farms. The wage analysis controls for a matching process by which workers are linked to farms of different sizes and technology uses. Using four surveys of employees on hog farms...

A bioeconomic model is developed to evaluate the tradeoff between the risk of resistance and increased productivity when refuge is planted in conjunction with transgenic pesticidal corn. The model is used to evaluate controversial refuge recommendations when producers are allowed to treat refuge...

This study examines soybean grower adoption of the Roundup Ready® (RR) weed management program with and without a residual herbicide application, and grower concerns regarding weed resistance to herbicides using telephone survey data from of 357 growers in 2007. It also estimates the pecuniary...

This study examined adoption of ten best management practices (BMPs) to control weed resistance to herbicides. Using data from a survey of 1,205 U.S. cotton, corn, and soybean growers, count data models were estimated to explain the total number of practices frequently adopted. Ordered probit...

Transgenic crops offer farmers a new and effective pest control option. However, the wide spread adoption of these crops could lead to a resistant pest population. This paper demonstrates how a pest refuge can be used to maximise the value of farm income in a dynamic model with genetic foundations.

The EPA has imposed mandatory refuge requirements for Bt crops to prolong the efficacy of Bt. Growers have no economic incentive to plant the required refuge because refuge crops are on average less productive and more risky. This paper evaluates refuge insurance--insurance that pays indemnities...
