Consider the payoff matrix we saw before, shown again to the right. If Firm 2 plays High Firm 1 will play Low. As it turns out, if Firm 1 plays
Low Firm 2 will wish to play
High. For Firm 1 Low is only best if Firm 2 plays High and for Firm 2
High is best only if Firm 1 plays
Low. Firm 1 Low, Firm 2 High is a Nash equilibrium because each is doing the best possible given what the other is doing. Can you see that this game has two Nash eqilibria?
