Altruistic Behavior and Correlated Equilibrium Selection

This paper studies new refinement concepts for correlated equilibria based on altruistic behavior of the players and generalizes some refinement concepts previ- ously developed by the authors for Nash equilibria. Effectiveness of the concepts, relations with the corresponding notions for Nash equilibria and with other cor- related equilibrium refinements are investigated. The analysis of the topological properties of the set of solutions concludes the paper
