    1.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.
    Now answer the following:
    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?
    2.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 BankCollude: Raise RatesDefect: Keep Rates Where They ArePNCCollude: 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?
