Farm Level Impacts of Bt Corn Adoption in a Developing Country: Evidence from the Philippines

This article examines the ex post farm-level impacts of Bt corn adoption in the Philippines. Using an econometric approach that addresses simultaneity, selection, and censoring problems, we show that Bt corn adoption provides modest but statistically significant increases in farm-level yields and profits. Furthermore, our results suggest that farm-level yield and profit impacts of Bt corn adoption are underestimated when censoring in the pesticide application variable is not considered in the estimation procedures. Previous literature have emphasized the importance of simultaneity and selection problems but this is the first study that have raised the issue of censoring problems in estimating the farm-level effects of Bt corn adoption.
