The Cournot and Bertrand models of Chapter 11 are other examples of games with unique Nash equilibria. We now consider two other situations. First, we examine games that have multiple Nash equilibria. Second, we consider games in which the firms’ strategies require them to choose randomly between possible actions.
Many oligopoly games have more than one Nash equilibrium. When a game has multiple Nash equilibria, we may be able to use additional criteria to predict the likely outcome. The scheduling or coordination ...
