Última Revisiting the Impact of Bt Corn Adoption by U.S. Farmers AgEcon Fernandez-Cornejo, Jorge; Wechsler, Seth James. This study examines the impact of adopting Bt corn on farm profits, yields, and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity. The model is estimated using nationwide farm-level survey data for 2005. Regression analysis confirms that Bt adoption is associated with increased profits, yields and seeding rates. However, the results of this analysis suggest that Bt adoption is not significantly related to insecticide use. This result appears to be related to the fact that insect infestation levels were lower in 2005 than they were in earlier years.

Ano: 2011 URL: http://purl.umn.edu/103327 Fifteen Years Later: Examining the Adoption of Bt Corn Varieties by U.S. Farmers AgEcon Fernandez-Cornejo, Jorge; Wechsler, Seth James. 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.
