内容简介：

In this paper, we propose an opposite model of noncooperative games (Nash, 1951): The Cooperation Problem. In this model, players can choose nothing but cooperation. We show that within this model, an ideal solution can be identified via sentiments (formally implemented in an axiomatic approach) as opposed to the Nash equilibrium identified within noncooperative games via rationality. Despite their oppositeness, the two models are complementary. We show that the cooperation problem helps solve the equilibrium selection problem---a notorious challenge of noncooperative games. And by combining the two models, we propose a new solution of normal-form games that describes “standards of behavior”---an initial quest of game theory (von Neumann and Morgenstern, 1944).
