The unprecedented growth in crop yields and agricultural total factor productivity over the past 70 years owes much to a series of biological innovations embodied in seeds, beginning with the development of hybrid crops in the United States in the early part of the 20th century, continuing with...

A notable feature of the adoption of genetically engineered (GE) corn is the rapid growth in seed prices accompanied by rapid increases in GE corn with multiple (stacked) traits, which have often seen to offer several advantages to farmers, particularly increased yields. This paper presents...

More than 15 years after their first successful commercial introduction in the United States, genetically engineered (GE) seeds have been widely adopted by U.S. corn, soybean, and cotton farmers. Still, some questions persist regarding the potential benefits and risks of GE crops. The report...

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...
