Abstract

A preliminary ex ante evaluation of potential impacts of stemborer, drought, and herbicide resistant genetically modified rice technologies in favorable and unfavorable environments in Asia is conducted in a general equilibrium framework. The total magnitude of the benefits from the three technologies is similar, and it indicates that emerging rice biotechnologies are likely to generate significant gains in economic well-being. The distribution of technology benefits across countries is, however, dramatically different. For countries with a larger proportion of production in unfavorable environments, the drought resistance technology produces larger gains than the stemborer technology. For countries with production primarily in favorable environments, the relative magnitude of gains depends on the proportion of direct seeded as opposed to transplanted rice production, with herbicide resistance technology appearing to provide greater gains than stemborer or drought resistant rice in direct seeded systems.
