ORIGINAL PAPER FDI and immigration: a regional analysis

Abstract Does immigration affect foreign direct investment? Existing studies on immigration and FDI have all looked at aggregate flows at the national level, arguing that immigrant networks lower the risk of foreign investment through increased infor-mation flows and a built in market. However, these national-level studies suffer from identification problems since many of the factors that attract immigrants also attract FDI. This study improves upon identification by looking at the regional distribution of both FDI and immigration from 10 source countries to the 50 US states. Using a unique measure of immigrant network size in each state, I find that immigration is not only positively correlated with FDI, it tends to lead it as well. Comparing a state with an average sized immigrant network to one with a network twice as large, I estimate that the stronger network state will get on average 20 more foreign-owned affiliates opening per year, an effect that is quite persistent over time. On average, more skilled immigrant communities attract more FDI, while the pull effect of immigration on FDI also increases with immigrant ties to native countries and with immigrant influence in local communities. These results suggest that immigration creates a positive external-ity in foreign investment that must be considered when assessing the costs and benefits of labor mobility. JEL Classification F2 · R3
