ABSTRACT

This paper studies the effects of Intellectual property rights (IPRs) on the pattern of trade in developing countries. Intellectual property rights, as a type of institutional endowment, could potentially change the pattern of trade through influencing the efficiency of technology transfer and contract enforcement. I develop a theoretical model in which a strengthening of IPRs improves technology transfer through licensing, which expands exports. To test for this, I construct a measure of patent intensity across industries to capture the significance of intellectual property rights. I find, both theoretically and empirically, that stronger IPRs expand exports in developing countries. The extent of this effect differs across industries. For industries with high patent intensities, the effects are larger. Moreover, I find that the effects are larger in developing countries with strong learning capacity. This is even true after controlling for other institutional effects and alternative determinants of international trade.
