带中介的贝叶斯说服

Bayesian Persuasion with Mediators

Itai Arieli, Yakov Babichenko, Fedor Sandomirskiy

摘要:

一个有信息的发送者通过一系列无信息的中介者与一个无信息的接收者进行通信,代理的效用取决于接收者的行为和状态。对于任何数量的调解人,发送者的最佳值的特点。对于一个调解员,表征有一个几何意义的约束concavification发送者的效用,最佳的说服需要相同数量的信号,没有调解员,调解员的存在是从来没有有利可图的发送者。令人惊讶的是,第二个调解人可能会提高价值,但最佳说服可能需要更多的信号。

英文摘要:

An informed sender communicates with an uninformed receiver through a sequence of uninformed mediators; agents' utilities depend on receiver's action and the state. For any number of mediators, the sender's optimal value is characterized. For one mediator, the characterization has a geometric meaning of constrained concavification of sender's utility, optimal persuasion requires the same number of signals as without mediators, and the presence of the mediator is never profitable for the sender. Surprisingly, the second mediator may improve the value but optimal persuasion may require more signals.
