On the Limits of Communication in Multidimensional Cheap Talk: A Comment
分析了一个多维状态和政策空间中的廉价谈话博弈，指出多维空间的一个特性——在一个维度上的沟通往往会泄露其他维度的信息——如何对沟通施加限制。
We analyze a cheap talk game, à la Crawford and Sobel, in a multidimensional state and policy space. A feature of the multidimensional state space is that communication on one dimension often reveals information on others. We show how this feature imposes bounds on communication.
