When people in developing countries worry about migration, they are usually concerned at the prospect of their best and brightest departure to Silicon Valley or to hospitals and universities in the developed world. These are the kind of workers that countries like Britain, Canada Australia try to attract by using immigration rules that privilege college graduates.

Lots of studies have found that well-educated people from developing countries are particularly likely to emigrate. A big survey of Indian households in 2004 found that nearly 40% of emigrants had more than a high-school education, compared with around 3.3% of all Indians over the age of 25. The “brain drain” has long bothered policymakers in poor countries. They fear that it hurts their economies, depriving them of much-needed skilled workers who could have taught at their universities, worked in their hospitals and come up with clever new products for their factories to make.

諸多研究表明，發(fā)展中國家受過良好教育的人才往往可能有移民傾向。2004年，曾針對印度家庭進行過一次大型調(diào)查，結(jié)果發(fā)現(xiàn)，近40%有移民傾向的人受過中學以上教育，而25歲以上的印度人只有約3.3%受過中學以上教育。“人才流失”問題長期以來一直讓發(fā)展中國家的決策者很苦惱，他們擔心這種情況會危及其經(jīng)濟發(fā)展，奪去他們緊缺的技術人才，而這些人才本該在他們自己的大學任教，在他們自己的醫(yī)院工作，為他們自己的工廠研發(fā)新產(chǎn)品。
