A case study in the chapter describes a phone conversation between the presidents of American Airlines and Braniff Airways. Analyze the game between the two companies. Suppose that each company can charge either a high price for tickets or a low price. If one company charges $300, it earns low profits if the other company also charges $300, and high profits if the other company charges $600. On the other hand, if the company charges $600, it earns very low profits if the other company charges $300 and medium profits if the other company also charges $600.
