Firms compete in many ways, of course, including competition through price, quality, and service. More importantly, they can compete fairly or unfairly. Unfair price competition can occur in several ways. Predatory pricing occurs when a product is temporarily priced below the actual costs as a means of driv¬ing competitors out of business. So, if a large national chain can sell a gallon of milk at below costs for a long enough period, it can drive smaller family-run grocery stores out of business. The size of the chain store allows it to absorb the losses, perhaps even indefinitely, in a way that is unavailable to the smaller store. Consumers may benefit from lower prices, but the larger community may suffer from fewer choices and lost competition.
