3. (5 points) Refer to the normal-form game of price competition in the payoff matrix below. Firm B Low Price High Price Low Price 0, 0 50, 10 Firm A High Price 10, 50 20, 20 Suppose the game is innitely repeated, and the interest rate is 20 percent. Both rms agree to charge a high price, provided no player has charged a low price in the past. This collusive outcome will be implemented with a trigger strategy that states that if any rm cheats, then the agreement is no longer valid, and each rm may make independent decisions. Will the trigger strategy be effective in implementing the collusive agreement? Please explain and show all necessary calculations
