I have an economics question where calculus is required in the answer. This one shot game is repeated infinitely t= 1, 2… Both firms use the same discount factor , 0 < < 1 Assume both firms use a grim trigger strategy. Derive the condition(s) for which there is a subgame perfect nash equilibrium of this game in which both firms cooperate in each repetition of the game. Firm 2 QH QL Firm 1 QH 1 ,1 10,0 QL 0,10 8,8 The first and second numbers in each cell represent the profits of firms 1 and 2 respectively.
