25. Suppose two firms, A and B, operate as duopolists in a particular market. The following payout matrix shows the profit for each firm (A's profit, B's profit) under four scenarios tied to whether both firms buy an advertisement (“ad”), neither firm buys an ad, or just one firm buys an ad: B buys ad B does not buy ad A buys ad (50, 50) (100, -50) A does not (-50,100) (80, 80) buy ad Which of the four scenarios corresponds to a Nash equilibrium? a) Both firms buy an ad (A’s profit is 50, B's profit is 50). b) Neither firm buys an ad (A's profit is 80, B's profit is 80). c) A buys an ad and B does not buy an ad (A's profit is 100, B's profit is -50). d) B buys and ad and B does not buy an ad (A's profit is -50, B's profit is 100). e) We cannot find the Nash equilibrium without additional information.
