This paper examines sets of Nash equilibrium in sender-receiver games that are stable against replacement by alternative Nash equilibria. Such stable sets exist. In partial common interest games they contain only informative equilibria.

This paper explores how efficiency structures language. It starts from the premise that one of language's central characteristics is to provide a means for saying novel things about novel circumstances, its creativity. As such it is a metaphor for the choice of organizational forms that can cope...

This paper studies the evolution of effective pre-play communication in game where a single communication round precedes a simultaneous-move, complete-information game.

This paper proposes as a solution concept for games sets of Nash equilibria that are stable against replacement by alternative Nash equilibria. We prove existence, examine some variants that are related to evolutionary solution concepts, and, most importantly, offer a unified approach to...
