摘要

以贸易预期收益最大化为目标，分析了双边贸易环境下的联合最优信息结构和机制。最优信息结构与第一优信息结构之间的贸易收益之差构成了信息不对称造成的最小损失。对于二元基础类型，可以达到95%以上的第一最佳，而没有信息设计的最优机制可能达到不到90%的第一最佳。对于更一般的类型分布，最优信息结构是类型空间的单调划分，最优机制是确定性的。导出了最优信息结构的必要条件，并给出了二元型情况下的封闭解。

Optimal information structures in bilateral trade

With the goal of maximizing expected gains from trade, this paper analyzes the jointly optimal information structure and mechanism in a bilateral trade setting. The difference in gains from trade between the optimal information structure and first best constitutes the minimal loss due to asymmetric information. With binary underlying types it is shown that more than 95% of first best can be achieved while the optimal mechanism without information design may achieve less than 90% of first best. For more general type distributions, the optimal information structure is a monotone partition of the type space and the optimal mechanism is deterministic. Necessary conditions for the optimal information structure are derived and a closed form solution is given for the binary type case.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
