Suppose two firms compete in micro-chip industry. Each period firm 1 produces q1 chips and firm two produces q2 chips and the firms face a demand curve of P = 50 − 10Q, where Q = q1 + q2. Both firms have a constant marginal cost of $20 per chip. Suppose the same industry exists for an infinite number of periods, the discount factor for profits is β = .8.

What are the static Nash equilibrium strategies for this market? That is, what is the NE if the game is played once? What are profits for a single period in this case?
Suppose the two firms agree to maximize joint profits rather than individual profits and share the proceeds equally(collusion). How many chips does each firm agree to make? What are firms profits for a single period?
Suppose the firms have agreed to maximize joint profits, but while firm 2 produces according to the agreement, firm 1 decides to cheat and maximize individual profits instead. How many chips does firm 1 decide to produce? What are profits for each firm?
Write down the grim trigger strategy.
If both firms follow the grim trigger strategy, what is the present discounted value of firm1’s profits?
If firm 2 follows the grim trigger strategy, but firm 1 deviates from it, what is the highest present discount value that firm 1 can obtain.
Is the grim trigger strategy an equilibrium? Why or why not?
