贝叶斯拍卖的信息获取

Information Elicitation for Bayesian Auctions

Jing Chen, Bo Li, Yingkai Li

摘要:

在本文中,我们设计了贝叶斯拍卖的信息获取机制。在贝叶斯机制设计中,参与者的私有类型分布通常被假设为公知,而信息获取则考虑参与者比决策者更了解私有类型分布的情况。为了削弱贝叶斯拍卖中的信息假设,我们考虑了一个信息结构中的分布的知识是任意分散的球员。在这样一个非结构化的信息设置,我们设计的机制,单位需求拍卖和添加剂拍卖,聚合玩家的知识,产生的收入是恒定的近似最优贝叶斯机制与一个共同的先验。我们的机制是两步显性策略真实的,收入随着玩家集体拥有的知识量而优雅地增加。

英文摘要:

In this paper we design information elicitation mechanisms for Bayesian auctions. While in Bayesian mechanism design the distributions of the players' private types are often assumed to be common knowledge, information elicitation considers the situation where the players know the distributions better than the decision maker. To weaken the information assumption in Bayesian auctions, we consider an information structure where the knowledge about the distributions is arbitrarily scattered among the players. In such an unstructured information setting, we design mechanisms for unit-demand auctions and additive auctions that aggregate the players' knowledge, generating revenue that are constant approximations to the optimal Bayesian mechanisms with a common prior. Our mechanisms are 2-step dominant-strategy truthful and the revenue increases gracefully with the amount of knowledge the players collectively have.
