Rationalizability and correlated equilibria. (English) Zbl 0652.90102
For finite n-person noncooperative games, the paper first proves an equivalence result between correlated rationalizability (which is based on the assumption that the rationality of the players is common knowledge) and a posteriori equilibrium (a refinement of subjective correlated equilibrium). Following this, the authors provide a similar result on the equivalence between independent rationalizability (which arises if each player believes that the others act independently) and conditionally independent a posteriori equilibrium. The paper ends with a discussion on the characterizations of objective correlated equilibrium and the standard Nash equilibrium.
