建立了一个概念模型来评估Bt玉米对风险的影响。结果强调了区分边际和总体风险效应的重要性，并表明Bt玉米对风险的影响主要取决于为该技术支付的价格。实证结果表明，根据价格，Bt玉米的风险可以轻微增加或减少，可以增加或减少玉米种植面积。此外，根据价格，Bt玉米可以为农民提供风险收益，即使Bt玉米的风险增加。
A conceptual model is developed to evaluate the effect of Bt corn on risk. Results highlight the importance of distinguishing between marginal and aggregate risk effects and demonstrate that the effect of Bt corn on risk depends crucially on the price paid for the technology. Empirical results show that, depending on the price, Bt corn can be marginally risk increasing or decreasing and can either increase or decrease corn acreage. Also, depending on the price, Bt corn can provide a risk benefit to farmers, even when Bt corn is risk increasing.
