Efficient and Durable Decision Rules with Incomplete Information
比较了不完全信息经济中六种效率概念，发现激励高效的决策规则可能被全体个体拒绝，进而定义了能抵抗这种拒绝的持久决策规则，并证明高效持久规则的存在。
We compare six concepts of efficiency for economies with incomplete information, depending on the stage at which individuals' welfare is evaluated and on whether incentive constraints are recognized. An example is shown in which an incentive-efficient decision rule may be unanimously rejected by the individuals in the economy. We define durable decision rules, which can resist such unanimous rejection, and show that efficient durable decision rules exist.
