双边贸易中的互动沟通

Interactive Communication in Bilateral Trade

Jieming Mao, Renato Paes Leme, Kangning Wang

摘要:

我们定义了一个模型的交互式通信,两个代理与私人类型可以交换信息之前,一个游戏是玩。该模型包含贝叶斯说服作为一个特殊情况下的一轮通信协议。我们将消息复杂度定义为实现最佳结果所需的最少交互轮数。我们的主要结果是,对于双边贸易,代理人不停止说话,直到他们达到一个有效的结果:要么代理人实现一个有效的分配在1000多轮的通信,或最佳的通信协议有无限的回合数。我们展示了一类重要的双边贸易环境,在这种环境中,通过少量的沟通就可以实现有效的分配。

英文摘要:

We define a model of interactive communication where two agents with private types can exchange information before a game is played. The model contains Bayesian persuasion as a special case of a one-round communication protocol. We define message complexity corresponding to the minimum number of interactive rounds necessary to achieve the best possible outcome. Our main result is that for bilateral trade, agents don't stop talking until they reach an efficient outcome: Either agents achieve an efficient allocation in finitely many rounds of communication; or the optimal communication protocol has infinite number of rounds. We show an important class of bilateral trade settings where efficient allocation is achievable with a small number of rounds of communication.
