An Empirical Analysis of Acreage Effects of Participation in the Federal Crop Insurance Program
通过多方程结构模型分析美国玉米、大豆、小麦和大麦种植面积对保险参与的响应，发现保费补贴增加30%仅使面积增加0.2%-1.1%，影响非常有限。
The extent to which crop insurance programs have resulted in additional land being brought into production has been a topic of considerable debate. We consider multiequation structural models of acreage response, insurance participation, CRP enrollment, and input usage. Our analysis focuses on corn and soybean production in the Corn Belt and wheat and barley production in the Upper Great Plains. Our results confirm that increased participation in insurance programs provokes statistically significant acreage responses in some cases, though the response is very modest in every case. In the most extreme cases, 30% decreases in premiums as a result of increased subsidies provoke acreage increases ranging from 0.2% to 1.1%. A number of policy simulations involving increases in premium subsidies are considered.
