In Praise of Brain Drain
Want to help the developing world? Hire away its best minds.
BY ROBERT GUEST | DECEMBER 29, 2011
My first child was delivered by a Nigerian midwife at a hospital in London.
It was an arduous labor. My wife, Emma, did not want to take a pain-soothing
epidural injection until it was absolutely necessary. After several hours,
when the contractions were excruciating, she asked for a jab. "Sorry, too
late,"

22ROBERT%20GUEST%22%20emma&pg=PT153#v=onepage&q&f=false> she was told -- the
baby was almost out.
So Emma winced and gasped and gave birth without anesthetic. The midwife was
impressed. "You did OK for a Caucasian," she said.
Like many rich countries, Britain imports planeloads of medical personnel
like my wife's midwife from poor countries like Nigeria; without them,
Britain's hospitals could barely function. But this transfer of intellectual
capital raises a troubling question: Is it fair for rich countries to poach
talent from poor ones? After all, it seems intuitive that "brain drain"
hurts the poor. Frank Dobson, when serving as Britain's health secretary,
<
http://www.independent.co.uk/life-style/health-and-families/health-news/nhs
-to-stop-poaching-nurses-738054.html> called it an "international disgrace."
If all the best doctors and engineers move to the West, who will staff
hospitals or build railways in Nigeria or Bangladesh? Simple justice, it
would seem, requires that rich countries should stop recruiting doctors and
engineers from poor ones.
Or does it? One of the most surprising findings in modern economics is that
the brain drain reduces global poverty. On balance, the outflow of talent
from poor countries to rich ones is actually good for poor countries -- and
even more so for poor people, since many escape poverty by emigrating.
Migration makes poor countries better off in several ways. First, the
prospect of earning big bucks working abroad spurs more people to acquire
marketable skills. They scrape together college fees and stay late in the
library. Having qualified as doctors or engineers, many will promptly
emigrate. But many will not. Some will fail to obtain a visa; others will
stay behind to look after their aging parents.
The Philippines, for instance, is the world's largest exporter of nurses.
Because so many eager students pack its private nursing schools, however, it
still ends up with more nurses per head than Austria. The same holds true
for other brain drainees as well. A
<
http://sites-final.uclouvain.be/econ/DP/IRES/2009018.pdf> 2009 study of 127
developing countries found that overall, the loss of skills to migration is
outweighed by the extra skills acquired by people contemplating it. That
study's authors, however, found in an
<
ftp://repec.iza.org/RePEc/Discussionpaper/dp819.pdf> earlier study that you
can have too much of a good thing: Once countries start to lose more than 20
percent of their college graduates, they reckon, brain drain starts to act
as a drag on economic growth. In other words, China and India, which export
only a small share of their skilled citizens, would benefit from exporting a
lot more. By contrast, war-scorched disaster zones such as the Democratic
Republic of the Congo, whose most talented people have fled in droves,
probably wouldn't.
The second way in which brain drain benefits poor countries is that migrants
often send money home. Consider the story of Haddish Welday. As a young man
in Ethiopia in the 1980s, when the country was a Marxist dictatorship,
Welday watched as 20 soldiers strolled into his biology class one day and
dragged off his teacher. The next day, the teacher's body was found lying in
the street, shot to death.
Welday lived in fear. Many days, he'd see bodies lying in the streets with
paper warnings pinned to them; "
<
http://books.google.com/books?id=8HSp_KW9C-YC&lpg=PT159&ots=YA6cuwuDC8&dq=%
22Let%20Red%20Terror%20Rain%20on%20Me%22&pg=PT159#v=onepage&q=%22Let%20Red%2
0Terror%20Rain%20on%20Me%22&f=false> Let Red Terror Rain on Me" was one
slogan that stuck in his memory.
So Welday decided to emigrate. After a detour through the Soviet Union, he
found his way to the United States, where he sought and received asylum.
When I met him in 2010, he was working as an accountant in Arlington,
Virginia. He has become American, yet he maintains close contact with his
homeland. He keeps a house in the Ethiopian city of Axum and sends money to
his mother every month. Sometimes he wires it to Ethiopia via Western Union;
sometimes he gives envelopes of cash to visiting Ethiopian friends, who
deliver it for him.
The money that migrants send home is a huge source of income for poor
countries. Recorded remittances to developing countries surged tenfold
between 1990 and 2009, from $31 billion to $316 billion. Unrecorded ones --
those envelopes stuffed with cash -- nudge the total even higher. All told,
remittances are more than double the amount of foreign aid sent to the
developing world, and unlike aid, they are seldom stolen by grasping
officials.
Remittances are also less volatile than other financial flows. Bad news can
make ordinary investors drop a country like a wriggling porcupine. Families
are not like that; Welday will not stop sending money to his mother just
because Ethiopia has suffered a corruption scandal or a coup.
Remittances are not only more stable than other forms of financing; they are
also countercyclical. That is, they tend to rise when other flows fall,
creating a useful cushion. When financial crises hit Mexico in 1995 and
Indonesia in 1998, the inflow of remittances actually increased, as worried
Mexican- and Indonesian-Americans sent cash home to their struggling
relatives.
Additionally, migrants often invest in their homelands. A study of 6,000
small businesses in Mexico, for instance, found that 20 percent of their
capital came from remittances, mostly from Mexicans working in the United
States. Diaspora investors are braver and more patient than others because
they have a long-term attachment to their homeland. Short-term shocks don't
worry them as much. A typical foreign investor in Nigeria would be very
frightened if he thought the local currency might collapse, since he wants
to convert his profits into dollars and take them home. For a
Nigerian-American investor, however, the same currency crash offers a chance
to buy up land cheaply and build a mansion for his eventual retirement.
Remittances also ease poverty. In Bangladesh, a country that sends tens of
thousands of construction workers to toil in oil sheikhdoms, families that
receive remittances typically rely on them for half their income. In nearby
Nepal, household surveys
<
http://www.migrationpolicy.org/pubs/MigDevPB_062507.pdf> suggest that
remittances account for perhaps half of the country's poverty reduction in
recent years.
Emigrants take their skills with them when they leave home, but the money
they send back helps others learn. It does so directly, when it is spent on
school fees. It also does so indirectly, when it puts food on a poor
family's table. Hungry children cannot concentrate in class. Amply fed
families are less likely to pull their daughters out of school and put them
to work in the fields.
The third way brain drain helps poor countries is that as migrants move back
and forth, they open channels for commerce. Countries trade more with
countries from which they have received immigrants. This is partly because
diaspora networks speed the flow of information: A Chinese trader in
Malaysia who spots a demand for plastic mobile-phone pouches will quickly
urge his cousin, who owns a factory in Zhejiang, to start cranking them out.
Because these two Chinese businessmen know each other, they trust each
other. This is hugely important -- it means they can seal a big deal with a
single phone call and get their product to market before anyone else.
Diaspora networks have been around for centuries, but they have grown much
more powerful of late, for three reasons. First, they are bigger than ever
before. Seventy million Chinese live outside mainland China, and 22 million
Indians live outside India. There are also hundreds of smaller networks,
from the Lebanese in West Africa to the South Koreans in the United States.
All told, there are
<
http://www.un.org/esa/population/publications/2009Migration_Chart/ittmig_wa
llchart09.pdf> 215 million first-generation migrants in the world, an
increase of 40 percent since 1990.
Second, diaspora networks have been massively empowered by modern
communications. In the old days, a transatlantic phone call might cost
several months' wages. Now it is free via Skype. So migrants stay constantly
and intimately in touch with the countries they came from, and with each
other.
Third, the places from which migrants come, such as India, China, and
Africa, are much more open to trade than they were a generation ago. When
China was a closed society, overseas Chinese traders had to make do with
linking one foreign port with another. Now they link the world to China and
China to the world.
These merchants speak the language, understand the culture, and know whom to
trust. In countries where the rule of law is unreliable -- which includes
most fast-growing emerging markets -- this matters. Some 70 percent of
foreign direct investment into mainland China passes through the Chinese
diaspora, broadly defined. American firms that hire Chinese-Americans find
it easier to do business in China without the aid of a joint venture.
Diasporas also accelerate the spread of technology to poor countries. Most
Asian scientists in Silicon Valley
<
http://www.ppic.org/content/pubs/report/R_502ASR.pdf> share ideas with
their friends back home. The world's cheapest refrigerator, which costs only
$70, was developed through the collaboration of brainy Indians in India and
brainy Indians in America. So was the software behind India's drive to give
all 1.2 billion of its citizens a biometric identity, thus enabling the
hundreds of millions who cannot prove who they are to open bank accounts and
borrow money.
The final, and most important, argument in favor of brain drain is that
migration is good for the migrants themselves. If they did not think so,
they would not move. Four out of five Haitians who have pulled themselves
out of poverty (if one uses a global poverty line of $10 a day) have done so
by moving to America. Nearly half of the Mexicans who have achieved this
modest standard of living have done so by crossing the Rio Grande. And tens
of thousands of infants are
<
http://www.cgdev.org/content/publications/detail/15552/> prevented from
dying each year by the simple fact that their parents emigrated.
In the battle against global poverty, the most powerful weapon is a welcome
mat.
