Abstract

This study presents recent results on the impact of adopting Bt corn on farm profits, yields, and seed and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity and uses farm-level survey data for 2010. Results confirm previous findings that Bt adoption is associated with increased profits and yields. However the Bt adoption is not significantly related to insecticide use as infestation levels in 2010 are very low and 90 percent of the farmers in the sample did not use insecticides at all.
