Abstract

We study learning in communication games. Our main finding is that a simple forward-looking learning rule leads to communication in a large class of games. This class is characterized by a partial-common-interest condition. In contrast, we show that a variety of purely backward looking dynamics may fail to guarantee communication. Memory is a partial substitute for looking forward: With long memory, backward-looking learning leads to communication in a class of games with perfect incentive alignment.
