This study contrasts the relationship between farm-size and adoption for two types of innovations, genetically engineered crops and precision farming, controlling for other factors. The analysis uses an extension of the McDonald and Moffit decomposition for the two-limit Tobit model.

The likelihood of adopting corn rootworm (CRW) Bt seed technology was analyzed using an ordered logit model. Data used to estimate the model came from USDAs 2001 Agricultural Resource Management Survey. Statistically significant variables include operator age, farm type, farm size, rootworm loss...
