Suppose that fixed costs for a firm in the automobile industry (start-up costs of factories, capitalequipment, and so on) are $5 billion and that variable costs are equal to $15,000 per finishedautomobile.Because more firms increase competition in the market, the market price falls asmore firms enter an automobile market, or specificallyP = 15,000 + 5000/n, wherenrepresentsthe number of firms in a market. Assume that the initial size of the U.S and the Europeanautomobile markets are 300 million and 533 million people, respectively.a.
