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.
