Significant attention has been paid to why a durable goods producer with little or no market power would monopolize the maintenance market for its own product. This paper investigates an explanation for the practice based on consumer switching costs and the decision concerning maintaining versus replacing used units. In our explanation, if the maintenance market is not monopolized, consumers sometimes maintain used units that are more efficiently replaced. In turn, monopolizing the maintenance market avoids this inefficiency. In contrast to most previous explanations for the practice, in our explanation, the practice increases both social and consumer welfare. (JEL D42, D43, D82, K21, L12, L42)
