Two firms operating in the same market must decide between charging a high price or a low
price. The Payoffs are as below. Firm A's profit is listed before the comma, B's profit after the
comma.
Firm B
Firm A
Low Price
High Price
Low Price

If each firm tries to choose a price that is optimal, regardless of the other firm's price, what is
the Nash equilibrium? Does either firm have a dominant strategy?
Fill in the chart attached and answer the following questions:
a) Bert's dominant strategy is to: (pick the correct answer below )
- no dominant strategy
- fish for 20 hours per week
-fish for 40 hours per week.
b) Ernie's dominant strategy is to: ( pick the correct answer below)
- no dominant strategy
- fish for 20 hours per week
-fish for 40 hours per week.
c) Is there a Nash Equilibrium? ( pick the correct answer below)
- No
- Yes, both fish for 20 hours per week
- Yes, one fisher for 40 and the other for 20.
- Yes both fish for 30 hours per week.
d) Is there an incentive for Bert and Ernie to collude? Why or why not?
Using a payoff matrix to determine the equilibrium outcome
Suppose there are only two firms that sell smart phones, Flashfone and Pictech. The following payoff matrix shows the profit (in millions of dollars) each company will earn, depending on whether it sets a high or low price for its phones.
Pictech Pricing
High
Low
Flashfone Pricing
High
11, 11
2, 18
Low
18, 2
10, 10
For example, the lower, left cell shows that if Flashfone prices low and Pictech prices high, Flashfone will earn a profit of $18 million and Pictech will earn a profit of $2 million. Assume this is a simultaneous game and that Flashfone and Pictech are both profit-maximizing firms.
If Flashfone prices high, Pictech will make more profit if it chooses a ______ price, and if Flashfone prices low, Pictech will make more profit if it chooses a _____ price.
If Pictech prices high, Flashfone will make more profit if it chooses a _____ price, and if Pictech prices low, Flashfone will make more…

Consider a Stackelberg competition game with three firms. Firm 1 chooses q1 first. Firm 2 observes q1 and chooses q2. Firm 3 observes both and chooses q3. These three firms are the only firms in the market, so the sum of their outputs is equal to total market supply, i.e. q1+q2+q3=Q. Suppose demand is given by P=12-Q. For simplicity of calculation, suppose each firm has marginal costs of 0, i.e. c1(q1)=0, c2(q2)=0 and c3(q3)=0. (1) What quantity does Firm 1 produce in the SPNE of the game?
