We study human capital depletion and formation in an economy open to o
ut-migration, as opposed to an economy which is closed. Under the assu
mption of asymmetric information, the enlarged opportunities and the a
ssociated different structure of incentives can give rise to a brain g
ain in conjunction with a brain drain. Migration by high-skill members
of its workforce notwithstanding, the home country can end up with a
higher average level of human capital per worker. (C) 1997 Elsevier Sc
