摘要 本文表明，当前一代转基因作物品种具有改善低收入国家经济福利的巨大潜力。在不使用农药的情况下，这些品种可能会增加低收入国家的农作物产量。当它们取代化学品时，它们将减少化学品对健康的负面影响。凭借较低的交易成本、适当的基础设施和知识产权，多种转基因技术将被引入。当仅对一小部分品种进行转基因改造时，转基因带来的收益将会减少，作物生物多样性可能会丧失。转基因技术的采用也会受到风险和信用考虑的影响。
Abstract This paper shows that the current generation of transgenic crop varieties has significant potential to improve economic welfare in low-income countries. These varieties might increase crop yields in low-income countries in cases when pesticides have not been used. They will reduce negative health effects of chemicals when they replace them. With low transaction costs, appropriate infrastructure, and access to intellectual property, multiple varieties of transgenics will be introduced. The gain from transgenics will be reduced, and crop biodiversity may be lost when only a small set of varieties is transgenetically modified. The adoption of transgenics will also be affected by risk and credit considerations.
