Price Discrimination and Copyright Law : Evidence from the Introduction of Dvds

This paper examines the welfare effects of intellectual property protection, accounting for firms' optimal responses to legal environments. I examine firms' use of indirect price discrimination in response to U.S. copyright law preventing direct price discrimination.

I find that studios' use of indirect price discrimination benefits consumers and harms retailers. Optimal pricing under E.U. copyright law further benefits studios and consumers. I also reanalyze these issues assuming continued DVD adoption
