Coordination and Imitation under Unawareness

This study focuses on discovered versions of coordination games with unawareness, and proposes a novel solution concept under unawareness named a successful-coordination equilibrium. In games with unawareness, coordination might fail because the models assume that agents are unaware of their realized actions. Then, when they observe the opponents' actions which they are unaware of, by teaching or asking their opponents how to play the opponents' actions, they might try to coordinate successfully. Although previous works propose models of discoveries, where players observe opponents' actions that they are unaware of and add these actions to their subjective games, they do not propose models of imitation that agents could add to the choices they did not have themselves, which was played by the opponents. We provide models of discoveries and imitations, showing that their revised games by discovering and imitating must propose a successful-coordination equilibrium
