This chapter reviews the economics literature on the development aspects of a substantially strengthened global regime of intellectual property rights (IPR). In this regime developing countries must adopt tighter standards governing patents, copyrights, and related policies, in order to protect global innovation. Some analytical literature finds that these changes could improve prospects for technology flows to poor countries, helping to integrate them into the global knowledge economy. Other authors raise deep concerns about whether these policy shifts will restrict growth through raising the costs of imitation, innovation, and acquiring international technologies. Poor countries may face permanently higher costs, raising questions about both the efficiency and equity implications. The chapter considers first the role of a balanced IPR regime in an overall economic development policy. This balance could involve widely varying protection standards at differing levels of economic development, growth, and social preferences. This situation is especially true in the world economy, where poorer countries may prefer to free ride on available international technologies. Much of the theoretical literature takes this view, suggesting that harmonized global policies could reduce innovation and growth. More recent literature takes a broader view of the ability of IPR to build global technology markets and support international information exchanges. Ultimately these are empirical questions and the available literature differs considerably in analytical approaches and conclusions. Thus, the chapter analyzes contributions from theory, empirical analysis, and case studies regarding prospective improvements or impediments to economic development arising from IPR reforms. These issues are especially important in public health and nutrition. The chapter concludes with an overview of how the globalized nature of IPR protection could affect developing countries. The essential point is that policy governing patents and copyrights needs to be embedded effectively in an overall economic development strategy.

Most current modeling approaches identify very small gains from trade reform. In this chapter, we examine recent developments in the literature to assess whether standard modeling approaches are mis-specifying, understating, or overstating the gains from trade reform. Key areas where the impacts of trade barrier reduction appear to be understated include the measurement of barriers; the aggregation of these barriers; process productivity gains, particularly those resulting from reallocation of resources between firms; product quality improvements and expansion of product variety; factor supply; and investment of gains from trade.
