‘Brain Drain’ Or ‘Brain Gain’? How The Emigration Of Skilled Workers Can Help Poor Countries’ Development

  • Published Date: April 2008


The emigration of skilled workers from poor countries to rich countries is often
viewed as a kind of predation through which the latter extract the most
valuable human resources from the former. But according to new research by
Michel Beine, Fréderic Docquier and Hillel Rapoport, a ‘brain drain’ may
be more than compensated for by a ‘brain gain’ if the opportunities for skilled
workers to emigrate to rich countries create an incentive for more people to
become educated in poor countries.
Their study, which is published in the April 2008 issue of The Economic
Journal
, finds that some developing countries – including Brazil, China and
India – benefit from the emigration of skilled workers. But others lose out,
especially small countries in sub-Saharan Africa and Central America. Overall
though, brain drain migration may be seen not only as increasing the number
of skilled workers worldwide but also the number of such workers living in
developing countries.
The brain drain has long been viewed as a serious constraint on poor
countries’ development. But recent theoretical analysis suggests that
migration prospects can foster investment in education at home.
The essence of the argument is that since the return to education is higher
abroad, migration prospects can raise the expected return to human capital
and, through this incentive effect, induce more people to invest in education
and training. Under certain conditions, this incentive effect (or brain gain) can
dominate that of actual emigration, in which case there is a net increase in
human capital for the source country.
This study takes advantage of a recent data set on emigration rates by
education levels in 127 developing countries to investigate this question
empirically. Human capital is measured as the proportion of people with
tertiary education in the population.
The researchers first estimate the effect of skilled migration prospects on
gross (or pre-migration) human capital levels. They find that doubling the
emigration rate of the highly skilled induces a 5% increase in gross human
capital formation among the native population (residents and emigrants
together). They also find that most countries that combine low levels of human
capital and low migration rates of skilled workers end up with an overall
positive effect.
In contrast, the brain drain appears to have negative effects in countries
where the migration rate of the highly educated is above 20% and/or where
the proportion of people with higher education is above 5%.
There appears to be more losers than winners, and the former tend to lose
relatively more (that is, when the losses are expressed in proportion of the
native skilled population) than what the latter gain. The situation of many
small countries in Sub-Saharan Africa and Central America, in particular, is
extremely worrisome.
In contrast, the main globalisers (such as Brazil, China and India) all seem to
experience important gains in absolute terms (headcounts). On aggregate,
the winners’ gains more than compensate the losers’ losses.
But given that there are winners and losers, the study shows that the brain
drain has important distributional effects among developing countries, a
dimension that has so far been absent from policy debates.
