What strategy does each firm use? A. The game does not have a Nash equilibrium. B. The Nash equilibria are for Firm 1 to produce 10 and Firm 2 to produce 20 and for Firm 1 to produce 20 and Firm 2 to produce 10. C. The Nash equilibrium is for Firm 1 to produce 20 and Firm 2 to produce 10. D. The Nash equilibrium is for Firm 1 and Firm 2 each to produce 10. E.

D. The Nash equilibrium is for Firm 1 and Firm 2 each to produce 10.

Explanation:

Firm 2

10 units 20 units

10 units 30 / 50 /

Firm 1 30 35

20 units 40 / 20 /

60 20

(firm 1 /

firm 2)

Firm 1's dominant strategy would be to sell 10 units with an expected payoff outcome = 30 + 50 = 80

Firm 2's dominant strategy would be to sell 10 units with an expected payoff outcome = 30 + 60 = 90

Since both firms have the same dominant strategy (to produce 10 units), there is a Nash Equilibrium where both firms produce 10 units and each one earns 30.
