Analyzing Payoff Tables 409

Although particular payoffs vary, the strategic implications of the three
payoff tables are the same. Assuming noncooperative play (i.e., no possibility
of communication or collusion), self-interest dictates the play of dominant
strategies. In the price war, a low price is most profitable, regardless of the com-
petitor’s price. Similarly, an arms buildup is the dominant strategy in the arms
race. (Fortunately, events in the former Soviet Union and the end of the cold
war have called a halt to the arms buildup.) Finally, in the generic prisoner’s
dilemma, defection is the dominant strategy. Note that the temptation payoff
from defecting is greater than the reward payoff from cooperation. In turn,
the penalty payoff if both players defect is greater than the sucker payoff if only
one player cooperates. In short, the logic of dominant strategies inevitably leads
to the inferior penalty payoffs under noncooperative play.
