The impact of integrated pest management (IPM) on pesticide use, toxicity and other environmental characteristics, yields, and farm profits is examined for grape growers. The method is generally applicable for technology adoption and accounts for self-selectivity, simultaneity, and theoretical...

Use of crop biotechnology products, such as genetically engineered (GE) crops with input traits for pest management, has risen dramatically since commercial approval in the mid-1990s. This report addresses several of the economic dimensions regarding farmer adoption of bioengineered crops,...

This paper estimates the on-farm impacts of adopting herbicide-tolerant soybean on herbicide use, yields, and farm profits, using an econometric model that corrects for self-selection and simultaneity and is consistent with profit maximization. The model is estimated using nationwide farm-level...

This study estimates farm-level effects of adopting 1997 herbicide-tolerant soybeans, Bt cotton, and herbicide-tolerant cotton and compares results obtained from various data sources. While adopters' yields are generally higher and pest control costs lower than those of nonadopters, considerable...

Agricultural biotechnology has been advancing very rapidly, and while it presents many promises, it also poses as many questions. Many dimensions to agricultural biotechnology need to be considered to adequately inform public policy. Policy is made more difficult by the fact that agricultural...
