Agricultural Pests as Common Property: Control of the Corn Rootworm
用公共财产资源模型分析杀虫剂抗性外部性，通过伊利诺伊州现金谷物农场数据估算玉米根虫控制中区域协调的收益，发现轮作替代杀虫剂时利润下降较小，延迟抗性收益有限。
Abstract Insecticide resistance is an increasingly widespread problem reducing effectiveness and necessitating a switch to more expensive controls. A common property resource model is used to describe potential gain from internalizing resistance externalities through regional coordination. A nonlinear programming model of an Illinois cash grain farm is used to estimate the gain for corn rootworm control where rotation to soybeans is an alternative to insecticide. Switching to rotation as resistance builds causes a relatively minor decrease in profits because soybeans are profitable. Gain from delaying resistance is slight. Co‐states give price changes necessary to alter externality production.
