Static Games
Two firms face the following payoff matrix: Given these profits, Firm 2 wants to match Firm 1 's price, but Firm 1 does not want to match Firm 2 's price. Does either firm have a dominant strategy? Does this game have a unique, pure-strategy Nash equilibrium? Identify all pure- and mixed-strategy Nash equilibria. (Hint: See Solved Problem 14.1.) A
Suppose Procter \& Gamble (PG) and Johnson \& Johnson (JNJ) are simultaneously considering new advertising campaigns. Each firm may choose a high, medium, or low level of advertising. What are each firm's best responses to its rival's strategies? Does either firm have a dominant strategy? What is the Nash equilibrium in this game?
