When you analyze finitely repeated games of the Prisoner's Dilemma forward and backward, you will find that: neither player will defect in a finitely repeated game. all players will cooperate in all periods. all players will cooperate until the second-to-last period. neither player will cooperate in any period.You are using the four-step recipe to determine if your rival will increase their prices. You have already considered all possible outcomes. The next step is to think about the "what ifs" separately. The third step is to evaluate your response. The fourth step would be to: put yourself in someone else's shoes. consider only one outcome. you should think about the "what ifs" all together. put yourself in your own shoes
