AS Macro Key Term: Brain Drain

A brain drain is a term that describes the movement of highly skilled or professional people from their own country to another country where they can earn more money. It has been used to describe net outward migration of people from several European Union countries in recent times (notably Ireland, Greece and Spain) - another phrase for this is human capital flight.

A sizeable brain drain can bring economic costs and benefits for the sending nation. One disadvantage is that countries lose out on the benefits that might have accrued from the resources used in educating people who leave. Add to this the loss of tax revenue from those who choose to live and work overseas. A sizeable loss of skilled workers (many of whom may be younger and therefore more geographically mobile) could lead to labour shortages in the sender country, putting upward pressure on wages and labour costs.

Some of this income earned overseas returns to the sender country in the form of remittances (adding to GNP) and many skilled migrants often leave only for a year or two - the percentage of permanent migration inside the EU is relatively small.
