论文摘要
我们介绍了一个发送者停止游戏的模型,在整个游戏中,世界状况都遵循IID。在每个时期,发件人都会观察当前状态,并向接收者发送消息,建议停止或继续。接收器只能看到消息,而不是状态,决定要么停止游戏,要么继续将游戏带到下一个时期。当接收者退出时,每个球员的回报是国家的函数,较高的状态会带来更好的回报。游戏的地平线可以是有限的或无限的。 在玩家足够耐心的情况下,我们在轻度条件下,在轻度条件下,在轻度条件下,我们证明了响应敏感性(即非贝斯)的响应性和独特性。响应式PBE具有非常简单的结构,该结构基于识别发件人的易于实施和计算类别的阈值策略的类别。在这些阈值策略的帮助下,我们得出了描述此PBE的简单表达式。事实证明,在此PBE中,接收器遵循发件人的建议。因此,令人惊讶的是,单独的发件人扮演决定性角色,无论接收者的回报功能如何,发件人始终为自己获得最佳的回报。
We introduce a model of sender-receiver stopping games, where the state of the world follows an iid--process throughout the game. At each period, the sender observes the current state, and sends a message to the receiver, suggesting either to stop or to continue. The receiver, only seeing the message but not the state, decides either to stop the game, or to continue which takes the game to the next period. The payoff to each player is a function of the state when the receiver quits, with higher states leading to better payoffs. The horizon of the game can be finite or infinite. We prove existence and uniqueness of responsive (i.e. non-babbling) Perfect Bayesian Equilibrium (PBE) under mild conditions on the game primitives in the case where the players are sufficiently patient. The responsive PBE has a remarkably simple structure, which builds on the identification of an easy-to-implement and compute class of threshold strategies for the sender. With the help of these threshold strategies, we derive simple expressions describing this PBE. It turns out that in this PBE the receiver obediently follows the recommendations of the sender. Hence, surprisingly, the sender alone plays the decisive role, and regardless of the payoff function of the receiver the sender always obtains the best possible payoff for himself.
