International policies toward protecting intellectual property rights have seen profound changes over the past two decades. Rules on how to protect patents, copyright, trademarks and other forms of intellectual property have become a standard component of international trade agreements. Most significantly, during the Uruguay Round of multilateral trade negotiations (1986-94), members of what is today the World Trade Organization (WTO) concluded the Agreement on Trade Related Intellectual Property Rights (TRIPS), which sets out minimum standards of protection that most of the world's economies have to respect. How will developing countries fare in this new international environment? Intellectual Property and Development brings together empirical research that assesses the effects of changing intellectual property regimes on various measures of economic and social performance - ranging from international trade, foreign investment and competition, to innovation and access to new technologies.
