We study the global innovation and diffusion of ideas by introducing trade into the model in Eaton and Kortum (1999 … intensity of innovation within countries over time and diffusion rates across countries. We find significant specialization … across the globe: some countries have high innovation rates, while other countries rely on diffusion. Although innovation is …

Worker mobility across firms can enhance innovation by spreading knowledge, but such mobility may also hinder … innovation by making firms reluctant to invest in R&D. A common way that firms limit workers' mobility is with noncompete … agreements (NCAs). We examine how the legal enforceability of NCAs affects innovation, as measured by patenting, using data on …

through their parent firms' networks of innovating plants. Cross-cluster innovation spillovers do not depend on the physical … physical distances. To rationalize these findings, and to inform policy, we develop a tractable model of spatial innovation … that features both within- and cross-cluster innovation spillovers. Based on our model, we derive a sufficient statistic …
