摘要 Abstract of the Paper	We investigate the impact of right-to-repair (RTR) policies on a manufacturer’s production decisions and market outcomes in the presence of competition from independent service organizations (ISOs) in the aftermarket. When repair services are horizontally differentiated but equal in quality, RTR ensures full aftermarket coverage in equilibrium and consistently enhances consumer welfare. The manufacturer may also benefit when product reliability is high and service differentiation is substantial, as RTR allows the firm to exit the aftermarket and concentrate on the primary market. With additional vertical differentiation, whereby ISOs offer lower-quality services, RTR can lead to an uncovered aftermarket when both product reliability and ISO quality are low, raising manufacturer profits but reducing consumer surplus. Conversely, when both product reliability and ISO quality are high, ISOs exclusively serve the repair market; however, social welfare declines, making RTR less desirable.
