Mechanism Design with Incomplete Information: A Solution to the Implementation Problem
证明在私人价值模型中,若代理人均衡中不使用弱占优策略,任何激励相容的分配规则都能成为机制的唯一均衡结果,从而避免多重均衡问题。
The main result of this paper is that the multiple equilibrium problem in mechanism design can be avoided in private-value models if agents do not use weakly dominated strategies in equilibrium. We show that in such settings, any incentive-compatible allocation rule can be made the unique equilibrium outcome to a mechanism. We derive a general necessary condition for unique implementation that implies that the positive result for private-value models applies. with considerably less generality to the common-value settings.
