Over the past 15 years, intellectual property rights (IPRs)-patents, copyrights, and trademarks-have moved from an arcane area of legal analysis and a policy backwater to the forefront of global economic policymaking. In the 1990s dozens of countries unilaterally strengthened their laws and regulations in this area, and many others are poised to do likewise. At the multilateral level, the successful conclusion of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs) in the World Trade Organization elevates the protection and enforcement of IPRs to the level of solemn international commitment.

The new global IPR system comes with both benefits and costs. Stronger IPRs protection should increase incentives for innovation and raise returns to international technology transfer. However, it also could raise the costs of acquiring new technology and products, shifting the global terms of trade in favor of technology producers and against technology consumers. In this context, the new regime raises international economic policy questions that evoke impassioned and exaggerated claims from both advocates and opponents of IPRs, particularly concerning sensitive issues such as patent protection of pharmaceuticals and biotechnological inventions, and copyright protection for internet transactions.

In the first comprehensive economic assessment of the effects of stronger international IPRs, Keith E. Maskus examines these competing claims through an analysis of the economic effects of extended international protection and partial harmonization of IPRs. He presents findings on the potential effects of stronger global IPRs, including likely impacts on foreign direct investment, technology transfer, and pricing under enhanced market power. The results bear directly on several important policy questions, including the construction of complementary initiatives on market liberalization and competition rules, and Maskus discusses whether priority attention should be devoted to them in the upcoming next round of global trade talks.
