Duopoly and Nash Equilibrium:
Two identical firms have MC = $3 and face a market demand function of: QD = 9 - P. there are no fixed costs.
a. Bertand: If the firms compete on the basis of (continuous) price, what is the Nash equilibrium if the game is played once? A finite number of times? Explain clearly.
b. If the Bertand game is indefinitely repeated, how can the firms sustain a cooperative Nash equilibrium? Calculate the temptation payoff and the value of δ*.
c. Stackelberg: If the firms compete on the basis of (continuous) quantity, what are the firms' reactive curve? Find the Nash equilibrium price and output and profit of the leader and the follower.
