Industry concentration is an important aspect of competition in many industries. Industry concentration is the extent to which a small number of firms dominate an industry (Table 3.10 “Industry Concentration”). Among circuses, for example, the four largest companies collectively own 89 percent of the market. Meanwhile, these companies tend to keep their competition rather polite. Their advertising does not lampoon one another, and they do not put on shows in the same city at the same time. This does not guarantee that the circus industry will be profitable; there are four other forces to consider as well as the quality of each firm’s strategy. But low levels of rivalry certainly help build the profit potential of the industry.
In contrast, the restaurant industry is fragmented, meaning that the largest rivals control just a small fraction of the business and that a large number of firms are important participants. Rivalry in fragmented industries tends to become bitter and fierce. Quiznos, a chain of sub shops that is roughly 15 percent the size of Subway, has directed some of its advertising campaigns directly at Subway, including one depicting a fictional sub shop called “Wrong Way” that bore a strong resemblance to Subway.
Within fragmented industries, it is almost inevitable that over time some firms will try to steal customers from other firms, such as by lowering prices, and that any competitive move by one firm will be matched by others. In the wake of Subway’s success in offering foot-long subs for $5, for example, Quiznos has matched Subway’s price. Such price jockeying is delightful to customers, of course, but it tends to reduce prices (and profit margins) within an industry. Indeed, Quiznos later escalated its attempt to attract budget-minded consumers by introducing a flatbread sandwich that cost only $2. Overall, when choosing strategic moves, Subway’s presence in a fragmented industry forces the firm to try to anticipate not only how fellow restaurant giants such as McDonald’s and Burger King will react but also how smaller sub shop chains like Quiznos and various regional and local players will respond.
