 abstract = {This paper examines the welfare effects of intellectual property protection, accounting for firms' optimal responses to legal environments and technological innovation. I examine firms' use of indirect price discrimination in response to U.S. copyright law, which effectively prevents direct price discrimination. Using data covering VHS and DVD movie distribution, I explain studios' optimal pricing strategies under U.S. copyright law, and determine optimal pricing strategies under E.U. copyright law, which allows for direct price discrimination. I analyze these optimal pricing strategies for both the existing VHS technology and the new digital DVD technology. I find that studios' use of indirect price discrimination under US copyright law benefits consumers and harms retailers. Optimal pricing under E.U. copyright law also tends to benefit studios and consumers. I also reanalyze these issues assuming continued DVD adoption.},
