Insecticide Use and Crop Rotation under Risk: Rootworm Control in Corn
扩展了经济阈值概念，结合杀虫剂和作物轮作两种害虫控制手段，在玉米-大豆农场模型中分析风险态度对最优控制组合的影响，发现作物保险可能促使风险规避型农民采用风险更高的种植方案。
Abstract The economic threshold concept is extended to a combination of two pest controls, insecticide and crop rotation, in a corn‐soybean farm model. Effect of risk attitudes on the optimal combination of controls is explored, using a stochastic simulation with random crop prices, yields, and rootworn damage. Crop insurance may cause a risk‐averse farmer to adopt a riskier cropping program. Reduced risk aversion causes the farmer to specialize in the more profitable corn crop. The insecticide and rotation thresholds both increase with reduced risk aversion. Depending on pest densities on individual fields, insecticide use may increase or decrease.
