Since cotton producers do not own legal rights to kill insect populations that are susceptible to insecticides, individual producers may have no incentive to account for future, insecticide-resistance productivity losses arising from their pest-management decisions. As a result, the collective actions of producers may increase the rate of resistance development relative to the rate that maximizes social welfare. Concerns regarding insect-pest development of resistance to Bt cotton prompted the Environmental Protection Agency to establish legal limits on the proportion of total acres individual producers may plant, representing the first attempt to regulate the development of insecticide resistance and the first instance of the use of refuge as a policy... |

This paper investigates the relationship between farm size and technology adoption by applying a model recently developed by Just and Zilberman to the choices of a sample of southwestern soybean farmers. The adoption of double cropping soybeans with wheat is evaluated with an expanded model which includes availability of specialized equipment and human capital. It is found that the empirical farm size-technology adoption relationship is consistent with risk aversion and a high covariance of returns between the old and new technologies. Accounting for human and physical capital differences across farms improves the power of the hypothesis tests. |

In 1996, Bt cotton became one of the first genetically engineered crops to be available commercially. This study focuses on the various sources and quality of information about Bt cotton profitability available to farmers in the Southeast and assesses the relative importance of such information in the farmers' adoption decisions. A model of the individual decision to adopt is developed to incorporate two recent theories of the role of information quality (the "effective information" hypothesis and the "popularity" hypothesis) as well as the effect of current technology depreciation. The data show some support for all three factors as determinants of adoption. |
