The long-term effect of intra-European migration on cognitive abilities in later life

The study raises the question about the long-term effect of intra-European migration on cognitive abilities in later life. In contrast to previous research that compares migrants to natives of the destination country, this study uses stayers in the European origin countries as reference group for migrants who moved to another European country earlier in life and are now growing old abroad. Selection into migration is addressed methodologically by applying an instrumental variable approach. Using the Global Bilateral Migration Database to generate the country- and time-specific share of emigrants as instrument for migration, the results indicate that intra-European migration turns out to have a negative long-term effect on the level of cognitive abilities.
