本文关注于委托代理问题中信息系统的选择问题,我们证明了在逆向选择和道德风险相对独立的混合情形下,关于代理人类型信息的累积分布函数满足一阶随机占优(FSD)的选择标准,关于代理人行为信息的累积分布函数满足二阶随机占优(SSD)的选择标准。最后,通过一个数值算例对上述选择标准的含义进行直观解释。
The paper focuses on the choice of the right information on the principal-agent problem,we prove that under hybrid conditions where adverse selection and moral hazard are relatively independent,the cumulative distribution function on agent's type satisfies First-order Stochastic Dominance(FSD)criteria,and the cumulative distribution function on agent's actions satisfies Second-order Stochastic Dominance(SSD) criteria.Finally,we visually explain the meaning of the selection criteria through a numerical example.
