We develop a discrete-choice model of differentiated products for U.S. corn and soybean seed demand to study the welfare impact of genetically engineered (GE) crop varieties. Using a unique dataset spanning the period 1996-2011, we find that the welfare impact of the GE innovation is...

This study exploits a novel dataset containing more than 89,000 farm-level surveys over a 17-year period to investigate how neonicotinoid seed treatments in maize, now ubiquitous, have affected the use of other insecticides. Neonicotinoid insecticides are the most used class of insecticides in...

The extensive adoption of genetically engineered (GE) varieties in U.S. agriculture has dramatically changed the patterns of pesticide use. How this process ultimately affects environmental risk remains an open question. Previous studies have typically relied on aggregate trends to infer the...
