On the coincidence of the coco value and Nash equilibrium payoffs

Abstract The cooperative-competitive value (the coco value) of Kalai and Kalai (Q J Econ 128(2):917–966, 2013) coincides with the payoffs of every Nash equilibrium in 2-person zero-sum games, and with the payoffs of every efficient equilibrium in 2-person common-interest games. This note presents several generalizations of these facts.
