Communication between rational agents
The paper deals with the study of credible communication in simple communication games. As a matter of fact, the author introduces a new solution concept which does guarantee communication in some games. The solution concept in question is called Credible Message Rationalizability and combines the assumptions of rich language and rationality of agents. That is, the author assumes both full rationality without imposing equilibrium conditions and the natural behaviour of agents about the use of language: agents have a propensity to speak the truth and to believe others speak the truth, but use the game's strategic incentives to check whether such behavior and beliefs are rational. The author also introduces an equilibrium version of the concept developed and proves the existence of the so-called Credible Message Equilibrium for simple communicaton games. The theory developed is illustrated by several examples.
