This paper theoretically and empirically analyzes the effect of strengthening intellectual property rights in developing countries on the level and composition of industrial development. We develop a North-South product cycle model in which Northern innovation, Southern imitation, and FDI are all endogenous.Our model predicts that IPR reform in the South leads to increased FDI in the North, as Northern firms shift production to Southern affiliates. This FDI accelerates Southern industrial development. The South's share of global manufacturing and the pace at which production of recently invented goods shifts to the South both increase. Additionally, the model also predicts that as production shifts to the South, Northern resources will be reallocated to R&D, driving an increase in the global rate of innovation. We test the model's predictions by analyzing responses of U.S.-based multinationals and domestic industrial production to IPR reforms in the 1980s and 1990s. First, we find that MNCs expand the scale of their activities in reforming countries after IPR reform. MNCs that make extensive use of intellectual property disproportionately increase their use of inputs. There is an overall expansion of industrial activity after IPR reform, and highly disaggregated trade data indicate an increase in the number of initial export episodes in response to reform. These results suggest that the expansion of multinational activity more than offsets any decline in the imitative activity of indigenous firms.
