Migration and Innovation: Evidence from Technology Take-offs. Prithwiraj Choudhury, October 13, 2018, Paper, "We investigate the relationship between international migration flows and the dynamics of innovation in the migrants’ receiving and sending countries. We find that countries are 3.5% more likely to become significant producers of a technology for every twofold increase in the stock of immigrants (30,000 people, on average) from countries that excel in that same technology. Our results are much stronger for skilled migrants, and are mostly driven by international migration rather than by cross-border trade or investments. We use a migration gravity framework to instrument for migrant stocks, reducing possible endogeneity concerns. We interpret these results as tangible evidence of migrants facilitating the diffusion of knowledge across nations." Link
