What circumstances lead a government to promote brain drain?

摘要

This paper aims to complement the existing theoretical brain drain literature, focusing on the interaction between education, skilled emigration and government intervention in a small open economy. This article first characterises different emigrationpatterns that may arise in equilibrium, then seeks the conditions that lead a government to promote brain-drain. The model shows that the government may promote skilled emigration among workers with intermediate skills even though the resulting brain drain decreases per capita income. Emigrants remittances outweigh the income they would produce if they did not emigrate. Therefore, the government makes less severe the fall in per capita income that follows the brain drain by encouraging emigration amongthose skilled workers who are more productive abroad.
