Brain drain worries policymakers around the world. For example, a search today in Google News gives a host of stories in the past month alone concerning efforts by universities in Vietnam to stop brain drain, demands for wage increases to stop the brain drain of doctors in Pakistan, claims that Malaysia’s brain drain hinders its economic progress, efforts to stem brain drain in Jamaica, a plea to “stop the brain drain” in Cyprus, and even fears of massive brain drain from the state of New York.
But does high-skilled emigration really pose such a threat? The last five years has seen a surge in empirical research on the subject, which John Gibson and I use to answer eight key questions about brain drain in a paper forthcoming in the Journal of Economic Perspectives and now out in the World Bank working paper series.
The 8 key questions addressed are: 1) What is brain drain? 2) Why should economists care about it? 3) Is brain drain increasing? 4) Is there a positive relationship between skilled and unskilled migration? 5) What makes brain drain more likely? 6) Does brain gain exist? 7) Do high-skilled workers remit, invest, and share knowledge back home? and 8) What do we know about the fiscal and production externalities of brain drain?
