This study develops a novel framework of heterogeneous producer attitudes towards risk to analyze different, stated and revealed, roles of crop insurance premium subsidies and underlying policy objectives of the government. The analysis reveals a strong connection and a complementarity between the roles of premium subsidies in increasing producer participation in crop insurance, inducing a desired separating equilibrium in the presence of asymmetric information, and transferring income to agricultural producers participating in the program. Developing an alternative design of premium subsidies that can achieve the stated government objective of increased producer participation and induce any desired separating equilibrium at significantly reduced costs, our study rejects the idea that the income redistribution taking place under the current policy design is necessary for increasing producer participation in crop insurance. Indeed, the current policy design reveals that premium subsidies are either a means of income redistribution or a policy failure.
本研究提出了一个生产者风险态度异质性的新框架,以分析作物保险保费补贴的不同、既定和揭示的作用,以及政府的基本政策目标。分析揭示了保费补贴在增加生产者参与作物保险、在信息不对称的情况下诱导理想的分离均衡,以及向参与计划的农业生产者转移收入方面的作用之间存在着很强的联系和互补性。为了以显著降低成本的方式实现既定的政府增加生产者参与度的目标,并诱导任何理想的分离均衡,本研究设计了一种替代的保费补贴方案,从而否定了现行政策设计下的收入再分配对于增加生产者参与作物保险的必要性。事实上,现行政策设计表明,保费补贴要么是一种收入再分配手段,要么是一种政策失败。
