Recent Research: How are Immigrant and Ethnic Workers Changing the Face of U.S. Innovation?
Foreign-born and ethnic workers continue to rapidly grow in their importance to the U.S. innovation economy, according to two recent studies that address this issue by examining the links between these groups and patenting activity.
In How Much Does Immigration Boost Innovation?, Jennifer Hunt uses state panel data from 1950 to 2000 to measure the extent of immigration's impact on U.S. patenting, state innovation economies and the science and technology workforce. Foreign-born residents account for just over ten percent of the working population, but represent about 25 percent of the science and engineering workforce. The 2003 Survey of College Graduates found that immigrants patent at double the rate of native U.S. residents. That study found that the difference was attributable to disproportionate educational attainment in science and engineering.
Hunt finds that a 1.3 percent increase in the share of the population composed of immigrant college graduates can increase patenting per capita by between 10 and 26 percent. Post-college immigrants had an even larger positive impact. In addition, immigrant college graduates can have positive spillovers for the non-immigrant population. While there may be some short-term crowding out of the native population as immigrants arrive, in the long-term, there is evidence that post-college immigrants can increase the patenting activity of their native neighbors.
Overall, Hunt argues that an immigrant college graduate contributes at least twice as much to patenting as a native counterpart.
