摘要：To be effective, policies that encourage farmers to use new technologies or practices need farmers both adopt and also keep using these technologies and practices. Adoption of new technologies has been widely analyzed in the literature. However, there is little known about the factors that cause farmers to keep using new technologies or quit using them. Using hazard function estimation, the current study investigates disadoption of Roundup Ready soybeans, injecting manure into the soil, and soil testing. The results of the current study show that over time farmers observe the true benefits and costs of these practices and they become more likely to disadopt these practices.
