英文文献摘要：
This paper examines the ex-ante benefits of transgenic research on drought in eight developing countries, including the potential magnitude of private sector profits. The framework employs country-specific agroecological-drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research. Risk benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits, representing 41 percent of total benefits across the eight countries. Further, estimated annual benefits of $US 93 million to the private sector suggest that significant incentives exist for private sector participation in varietal drought tolerance research.
这篇论文考察了在8个发展中国家进行干旱转基因研究的前期收益，包括私营部门利润的潜在规模。该框架采用了特定国家的农业生态干旱风险区，在估计生产者和消费者从研究中获得的利益时，考虑了产量的增加和产量差异的减少。减少产量差异带来的风险收益是干旱研究总收益的一个重要组成部分，占8个国家总收益的41%。此外，据估计，私营部门每年可获得9300万美元的收益，这表明私营部门参与品种耐旱研究存在重大的激励机制。
