Must-Read: Tim Harford: The Real Benefits of Migration: “UK Home Secretary Theresa May gave a speech… designed to polarise…. She succeeded…

…One statement… found the spotlight…. (Translation: immigration costs us nothing but we want to reduce it anyway.) Is May’s summary of the evidence correct? Probably not…. But there was a far bigger lacuna… [that] most commentators… missed it…. Migrants… prosper hugely… yet that prosperity hardly ever figures in debates about immigration. This is odd. I would not expect schools to fare well on a cost-benefit analysis if we ignored any gains to the under-18s. Nor would hospitals look like a good investment if we counted only the advantages to non-patients. Yet it seems that migration may still be mildly beneficial even after disqualifying any benefit to the people most likely to gain–the migrants. That is remarkable….

One might make the case that because migrants are foreign nationals, we are entitled to make their welfare a lower priority. My colleague Martin Wolf is one of the few commentators to bother asserting this openly; most simply seem to assume that foreigners count for nothing…. Being open to migration from poor countries is perhaps the best anti-poverty programme that rich countries can offer…. Whether foreigners should count as sentient beings in a British cost-benefit analysis is something I’ll leave to the philosophers….

How real a problem is… brain drain?…. Where developing countries do train large numbers of skilled workers–as with the Philippines, a world centre for nursing and midwifery–they also manage to keep a reasonable number of them at home. And… migrant remittances… [are] three times as much as is sent in official development assistance. Migrant networks can help make trade flow smoothly too. Then there is the simple matter of respecting individual liberties…. If we have gained anything from the harrowing images of desperate refugees, it is an appreciation that they are human. Economic migrants are human too… not pheasants to poach; nor brains to drain.

Must-Read: Michael Clemens: The South Pacific Secret to Breaking the Poverty Cycle: “The average Tongan household that participated was earning just NZ$1,400 per year…

…before these jobs. The average worker who participated earned NZ$12,000 for just a few months of work. It multiplied low-income workers’ earnings by a factor of 10. Almost no other antipoverty project you’ve ever heard of can claim that. Imagine what that did to poverty…. This project was ‘among the most effective development policies evaluated to date.’ And it did that not by taking money away from New Zealanders, but by adding value to the New Zealand economy. What’s working against poverty? International labor mobility….

The last time the United Nations set global goals to fight poverty, back in 2000, it completely ignored the power of labor mobility. The Millennium Development Goals, bizarrely, mentioned migration exclusively in negative and harmful terms…. This time… [they] at least mention migration…. But they decline to mention any possibility of actually facilitating migration…. The authors… still think that mobility doesn’t matter much for global poverty. That just does not make sense in a world where remittances to poor countries are several times as large as foreign aid. It does not make sense in a world where barriers to mobility cost the world trillions of dollars every year. What’s working against poverty is international mobility. And it will keep working to help meet the Global Goals for fighting poverty–largely in spite of them.
