Brain Drain: Some Evidence from European Expatriates in the United States
The paper uses U.S. Census data from 1990 and 2000 to provide evidence on the labor market characteristics of European-born workers living in the U.S. It is found that there is a positive wage premium
associated with these workers, and that the highly skilled are overrepresented compared with the source country, more so when one moves up the skill ladder.
