Asymptotic Efficiency in Large Exchange Economies With Asymmetric Information
给出了非对称信息交换经济中，当经济被充分复制时存在激励相容、个体理性且近似有效的分配的条件，并讨论了其在拍卖、柠檬市场和保险问题中的应用。
The authors provide conditions on an exchange economy with asymmetric information that guarantee that when the economy is replicated sufficiently often, there will be an allocation that is incentive compatible, individually rational, and nearly efficient. The main theorem covers both the case in which aggregate uncertainty remains when the economy is replicated and the case in which replication eliminates aggregate uncertainty. In addition, the authors demonstrate how their theorem does or does not apply to standard asymmetric information problems such as the buyer's bid double auction problem, Akerlof's lemons problem, and insurance with asymmetric information.
