4. Lufthansa (LH) and British Airways (BA) are engaging into the following one-shot simultaneous game: if LH advertises for a fair from Frankfurt to Paris and BA does not, LH will make $20 million in profits and BA will make $6 million. If BA advertises and LH does not, LH will make $2 million and BA will make $6 million. If LH advertises and BA advertises, each firm earns $10 million. If neither firm advertises, BA will make $8 million and LH will make $4 million.
(a) Write the payoff matrix for the above game.
(b) Does LH have a dominant strategy?

5. Wilson has been producing tennis racquets for many decades and continues to implement strategies that make it a leader in the tennis racquet industry. Suppose that when Wilson and its largest rival,Babolat, advertise, each company earns $0 billion in profits. When neither company advertises, each company earns profits of $8 billion. If one company advertises and the other does not, the company that advertises earns $48 billion and the company that does not advertise loses $1 billion. Under what conditions could collusion be profitable? Explain.
