Unique Implementation of Action Profiles: Necessary and Sufficient Conditions*
研究了委托人实施给定行动组合并按照给定补偿方案支付代理人的一般问题，给出了在子博弈完美均衡中可实施的行动组合和补偿方案的充要条件。
We study the general problem of a principal who desires to implement a given vector of actions and pay the agents according to a given compensation scheme. Previous work has provided mechanisms for implementation in various special cases. In this paper we fully characterize the set of action proflles and compensation schemes implementable in sub game perfect equilibrium, providing necessary and sufficient conditions for implementation.
