Abstract

We consider the following belief free solution concepts for games with incomplete information: (i) incomplete information rationalizability, (ii) incomplete information correlated equilibrium and (iii) ex post equilibrium. We present epistemic foundations for these solution concepts and establish relationships between them. The properties of these solution concepts are further developed in supermodular games and potential games.

Keywords: Correlated equilibrium, Rationalizability, Ex post equilibrium, Belief free, Types, Payo types, Belief types, Supermodular games, Potential games
