摘要：This paper uses conditional quantile regression to analyze the effects of genetically modified (GM)seed technology and management on production risk in agriculture, with an application to thedistribution of corn yield in Wisconsin. Using the certainty equivalent (CE) as a welfare measure,our analysis decomposes the welfare effects of risk, management, and agricultural technologyinto two parts: mean effects and risk premium (measuring the cost of risk). We documenthow biotechnology and management interact to improve agricultural productivity and reducefarm risk exposure. For corn, we find that GM European Corn Borer (GM-ECB) technologyconsistently increases CE (the increase ranging from +4.6% to +11.8%) and that a significantpart of this increase can come from risk reduction. We also show that the benefits of the GMECBbiotechnology are heterogeneous: they vary significantly across regions as well as acrossmanagement schemes.
