Digital Rights Management and Technological Tying

This paper analyzes DRM-based technological tying, where the content and hardware form a system. A closed DRM system makes the legal content incompatible with a rival’s hardware, whose users must then obtain illegal copies. The main finding is that the tying firm gains market power in a competitive hardware market and invests in product upgrades at a later stage. Welfare implications of the policy that requires an open DRM system are also discussed.
