Automobile Advertising. Consider two automobile companies that are considering advertising campaigns. If neither firm advertises, each will earn net revenue of $5 million. If each spends $10 million on advertising, each firm s net revenue will be $12 million. If one advertises and the other does not, the firm that advertises will earn $17 million in net revenue, while the firm that does not will earn $1 million. Draw a game tree and predict the outcome. From the industry perspective, do the benefits of advertising exceed the costs?
