Migration and Development Brief
Migration and Development Brief 4
International migrants are an important channel for the transmission of technology and knowledge. The so-called “brain drain” associated with better educated citizens of developing countries working in high-income countries is acute in some developing countries. Developing countries benefit, however, from the temporary migration of managers and engineers; the return of well-educated emigrants; and contact with a technologically sophisticated diaspora. Remittances sent by migrants also promote technology diffusion by making investments more affordable.
