Asymmetric information and the brain drain.
"Within an asymmetric information framework, we investigate the effects of subsidies for return [to developing countries] when the size of the foreign student population is endogenous.  Given the stability condition and the assumption that the education system is effective in the home country, we show that subsidies for return always act to improve the average ability of returning Ph.D.s but the impact upon the number of emigrants is ambiguous."
