研究了在重复委托代理问题中,基于私有信号的非递归均衡(如审查策略)相对于递归均衡的效率改进,发现其改进幅度很小,无法加速向有效收益前沿的收敛速度。

Abstract

In repeated principal‐agent problems and games, more outcomes are implementable when performance signals are privately observed by a principal or mediator with commitment power than when the same signals are publicly observed and form the basis of a recursive equilibrium. We investigate the gains from nonrecursive equilibria (e.g., “review strategies”) based on privately observed signals. Under a pairwise identification condition, we find that the gains from nonrecursive equilibria are “small”: their inefficiency is of the same 1 − δ power order as that of recursive equilibria. Thus, while private strategies or monitoring can outperform public ones for a fixed discount factor, they cannot accelerate the power rate of convergence to the efficient payoff frontier when the folk theorem holds. An implication is that the gains from withholding performance feedback from agents are small when the parties are patient.
