We analyze simple adaptive learning processes to model the evolution of effective communication in cheap-talk games with initially meaningless signals. We suggest that learning rules may be sensitive to the information available to players at the population level. As a consequence, learning...

As documented in the dynamics and outcomes, agents learn to attach meaning to a priori meaningless messages. For the common interest game, Game 1, this chapter observe the efficient separating outcome, although the learning process is gradual. For the partial common interest game, Game 2, the...
