Estimating the Benefits of Bt Corn and Cost of Insect Resistance Management Ex Ante

摘要

This paper estimates fanner benefits for corn rootworm (CRW) active Bt corn and costs of complying with Environmental Protection Agency insect resistance management requirements. The estimates are obtained from farmer survey data that were collected in Minnesota in 2002, just prior to the commercial release of CRW Bt corn. Benefit estimates range from 14 dollar to 33.4 million dollar, while compliance cost estimates range from 3.5 to dollar 8.7 million dollar depending on whether or not CRW Bt corn also controlled the European corn borer and whether or not it was approved for sale in major export markets,
