Using newly developed Korean immigration data, we empirically test the networks effects prediction. The main contribution of this article is to go one step further in finding empirical evidence to support heterogeneity in networks effects. Using their visa type, we separate immigrants into two groups—skilled immigrants and unskilled immigrants—and find that only skilled immigrants increase Korean imports from their home countries.
