Firm A and Firm B have made an implicit agreement to restrict output. The payoffs from respecting the agreement and cheating are shown in the Table below Firm B Restrict Output Expand Output Firm A Restrict Output 50, 35 20, 40 Expand Output 60, 10 25, 20 1. Identify the Nash equilibrium of one-shot interaction 2. Assume that the firms are playing an infinitely repeated game in which output decisions must be made every period. Both firms are using grim trigger strategies. Identify the value of the interest rate used for discounting necessary for both firms to keep the output restriction agreement
