In 1999, over $800 billion purchases were charged on credit cards, and this total is increasing at a rate of over 10% a year. At first glance, the credit card market would seem to be a rather concentrated industry. Visa, MasterCard, and American Express are the most familiar names, and over 60% of all charges are made using one of these three cards. But on closer examination, the industry seems to exhibit most characteristics of perfect competition. Consider first the size and distribution of buyers and sellers. Although Visa, Mastercard, and American Express are the choices of the majority of consumers, these cards do not originate from just three firms. In fact, there are over 6,000 enterprises (primarily banks and credit unions) in the U.S. that offer charge cards to over 90 million credit card holders. One person's Visa card may have been issued by his company's credit union in Los Angeles, while a next-door neighbor may have acquired hers from a Miami bank when she was living in Florida. Credit cards are a relatively homogenous product. Most Visa cards are similar in appearance, and they can all be used for the same purposes. When the charge is made, the merchant is unlikely to notice who it was that actually issued the card. Entry into and exit from the credit card market is easy as evidenced by the 6,000 institutions that currently offer cards. Although a new firm might find it difficult to enter the market, a financially sound bank, even one of modest size, could obtain the right to offer a MasterCard or a Visa card from the present companies with little difficulty. If the bank wanted to leave the field, there would be a ready market to sell its accounts to other credit card suppliers. Thus, it would seem that the credit card industry meets most of the characteristics for a perfectly competitive market.
