2. (12 points) Consider the following payoff matrix: High Price Low Price High Price 60, 60 5, 260 Low Price 260, 5 10, 10 Two rms play this pricing game repeatedly an innite number of times. Suppose each rm adopts a grim trigger strategy that says they will choose a high price in the rst period of the game, and they will continue to choose a high price as long as the other player has chosen a high price in the previous period. If one rm chooses a low price in any period, then the other rm will choose a low price in all subsequent periods until the end of time. Characterize the values of the discount rate, r, which will lead to the High Price/High Price outcome being played in each period as a non-cooperative Nash Equilibrium
