Senior fellow Michael Clemens's piece on the benefits of international migration was featured in The Guardian's Poverty Matters blog.
From the Article
What is the biggest single drag on the beleaguered global economy? Opponents of globalisation might point to the current crisis, which shrank the world economy by about 5%. Proponents of globalisation might point to the remaining barriers to international flows of goods and capital, which also serve to shrink the world economy by approximately 5%. That sounds like a lot.
But the truly big fish are swimming elsewhere. The world impoverishes itself much more through blocking international migration than any other single class of international policy. A modest relaxation of barriers to human mobility between countries would bring more global economic prosperity than the total elimination of all remaining policy barriers to goods trade - every tariff, every quota - plus the elimination of every last restriction on the free movement of capital.
I document that remarkable fact in a new research paper. Large numbers of people wish to move permanently to another country – more than 40% of adults in the poorest quarter of nations. But most of them are either ineligible for any form of legal movement or face waiting lists of a decade or more. Those giant walls are a human creation, but cause more than just human harm: they hobble the global economy, costing the world roughly half its potential economic product.
