To test this argument, we develop an endogenous growth model with knowledge spillovers and imperfectly elastic labor supply. Innovators invent new varieties and earn monopolistically competitive rents during the life of a patent, but create deadweight losses in the labor market. When the patent expires, imitators copy innovators and competition ensues. Over time, firms continuously make follow-on \u201cprocess\u201d innovations and learn from each other, resulting in faster productivity growth relative to monopoly. Enough such innovations reverse the logic of patents: higher spillovers can imply a shorter T \u2217 if, despite a diminution in product innovation, growth from process innovations matters more. Our calibration to the US economy offers T \u2217 between 6 and 11 years, in contrast with the current global standard of 20. A counterfactual without spillovers yields T \u2217 \u2248 34, suggesting that lost opportunities for productivity growth from competition matter substantially for the optimal life of a patent. We also find that optimal patent policy depends crucially on the distribution of spillovers across industries. As such, we argue for a macroeconomic approach to patent policy instead of restricting attention to individual industry estimates.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ocorrer\u00e1 no dia\u00a027\/04\/2023, QUINTA-FEIRA, \u00e0s 10h30min \u00a0o Semin\u00e1rio de Pesquisa \u201cSymbiotic Competition and Intellectual Property\u201d na \u00e1rea de Economia Aplicada ministrado pelo Prof\u00ba\u00a0Rafael Guthmann (Universidad Alberto Hurtado, Chile) Autores: Rafael Guthmann (Universidad Alberto Hurtado) e David M.
