Robust performance evaluation of independent agents
研究了委托人无法观察代理人行动及可用行动集时，如何设计稳健最优合同，发现必须将代理人激励薪酬挂钩，在对称二元环境下需采用联合绩效评估。
A principal provides incentives for independent agents. The principal cannot observe the agents' actions, nor does she know the entire set of actions available to them. It is shown that an anti‐informativeness principle holds: very generally, robustly optimal contracts must link the incentive pay of the agents. In symmetric and binary environments, they must exhibit joint performance evaluation —each agent's pay is increasing in the performance of the other.
