The payoff matrix below shows the payoffs for Firm A and Firm B, each of whom can either "cooperate" or "cheat." The numbers in parentheses are (payoff for A, payoff for B).
Firm B Cooperate Cheat
Cooperate (45,45) (15, x)
Cheat (x,15) (30,30)
Firm A
What is the minimum value for x in order for both firms' cheating to be the only Nash equilibrium?
