5. Assume a one-shot simultaneous move game, with two players (i.e. Player A and Player B). Given the following payoff matrix Player B B1 B2 B3 A1 8, 8 7, 13 7, 7 Player A A2 9, 3 6, 20 7, 6 A3 10, 10 6, 6 9, 4 (payoff A, payoff B) a) Identify the Nash equilibrium(s), if any. Show your work. (3 marks) b) Assume that the game is now played repeatedly with no end in sight. Provide a strategy for Player B. Is this an optimal strategy for Player B? (4 marks)
