We show that in a large class of extensive form games, the assumption that rationality is common knowledge cannot be maintained throughout the game. It is shown that this can have serious consequences on traditional extensive form solution concepts (such as Selten's (1965) notion of subgame-perfect Nash equilibria).Read More
