Jag skrev nyligen om en studie som visar att invandrare kan kopplas till mer innovationsverksamhet i Tyskland. Nu har det kommit belägg för en liknande effekt i USA. Studien ”Immigration, Innovation and Growth” finner fyra saker:

First, immigration has a positive impact on innovation, measured by patenting of local firms. Second, immigration has a positive impact on measures of local dynamism, as endogenous growth theory predicts. Third, the positive impact of immigration on innovation percolates over space, but spatial spillovers quickly die with distance. Fourth, the impact of immigration on innovation is stronger for more educated migrants.

Hur förhåller det sig i Sverige, månntro?
