摘要：

U.S. agriculture has seen a rapid adoption of biotechnology over the last two decades. This study investigates how biotechnology has affected U.S. farm input demand and agricultural productivity. The analysis relies on data at the national level and at the state level for selected states in the Corn Belt. It evaluates the rate of technological change and price elasticities of demand for agricultural inputs over time. The study documents the evolving biases in technological change in agriculture. It finds evidence that farm input demands have become more price inelastic.
