Monopolies can sometimes find themselves in difficult financial situations that lead to losses.
Suppose Mr. Burns’ power company has a monopoly for providing electricity in Springfield.
His costs of upkeep are so high that he is consistently losing money.
a.) Show this outcome in a completely labeled graph. Clearly identify all parts of your graph,
including the best price and output for the firm as well as the losses.
b.) What happens to the market output when Mr. Burns raises the price he charges?
c.) Will this stop his losses? Why or why not?

Assume the following game is played one time only. Based on the information in the payoff
matrix below, PNC Bank and Citizens Bank are considering an implicit collusive agreement
on interest rates. Payoffs to the two firms are represented in terms of profits in thousands of
dollars.
Citizens Bank
Collude: Raise
Rates
Defect: Keep Rates
Where They Are
PNC
Collude: Raise
Rates
(900, 600)
(700, 800)
Defect: Keep Rates
Where They Are
(1100, 300)
(800, 400)
a.) Does PNC have a dominant strategy? What is it?
b.) Does Citizens have a dominant strategy? What is it?
c.) Does the result of your answer change if the game is played an infinite number of times?
Why or why not? Properly use game theoretic terminology in your answer.
