A new wave of mass migration has begun
What does it mean for rich-world economies?
Last year 1.2m people moved to Britain—almost certainly the most ever. Net migration (ie, immigrants minus emigrants) to Australia is currently twice the rate before the covid-19 pandemic. Spain’s equivalent figure recently hit an all-time high. Nearly 1.4m people on net are expected to move to America this year, one-third more than before the pandemic. In 2022 net migration to Canada was more than double the previous record. In Germany it was even higher than during the “migration crisis” of 2015. The rich world as a whole is in the middle of an unprecedented migration boom.
Its foreign-born population is rising faster than at any point in history .
What does this mean for the global economy? Not long ago it seemed as if many wealthy countries had turned decisively against mass migration. In 2016 Britons voted for Brexit and then Americans for Donald Trump—both political projects had a strong anti-migrant streak.
这对全球经济意味着什么？不久前，似乎许多富裕国家已决定反对大规模移民。2016年，英国人投票支持英国退欧，美国人投票支持唐纳德•特朗普(Donald Trump) ，这两个政治项目都有强烈的反移民倾向。
In the global wave of populism that followed, politicians from Australia to Hungary promised to crack down on migration. Then covid closed borders. Migration came to a standstill, or even went into reverse, as people decided to return home.
Between 2019 and 2021 the populations of Kuwait and Singapore, countries that typically receive lots of migrants, fell by 4%. In 2021 the number of emigrants from Australia exceeded the number of immigrants to the country for the first time since the 1940s.
In some places the surge in migration has brought back a sense of normality. Singapore’s foreign workforce recently returned to its pre-pandemic level. In other places it feels like a drastic change. Consider Newfoundland and Labrador, Canada’s second-smallest province by population.
Long home to people of Irish-Catholic descent—with accents to match—net migration to the province is running at more than 20 times the pre-pandemic norm. St John’s, the capital, once fairly homogeneous, feels more like Toronto every time you visit.
Heart’s Delight, a small rural village, now has a Ukrainian bakery, Borsch. The provincial government is setting up an office in Bangalore to help recruit nurses.
The new arrivals in Newfoundland are a microcosm of those elsewhere in the rich world. Many hundreds of Ukrainians have arrived on the island—a tiny share of the millions who have left the country since Russia invaded.
Indians and Nigerians also appear to be on the move in large numbers. Many speak English. And many already have familial connections in richer countries, in particular Britain and Canada.
Some of the surge in migration is because people are making up for lost time. Many migrants acquired visas in 2020 or 2021, but only made the trip once covid restrictions loosened.
Yet the rich world’s foreign-born population—at well over 100m—is now above its pre-crisis trend, suggesting something else is going on.
The nature of the post-pandemic economy is a big part of the explanation. Unemployment in the rich world, at 4.8%, has not been so low in decades. Bosses are desperate for staff, with vacancies near an all-time high. People from abroad thus have good reason to travel.
Currency movements may be another factor. A British pound buys more than 100 Indian rupees, compared with 90 in 2019. Since the beginning of 2021 the average emerging-market currency has depreciated by about 4% against the dollar.
This enables migrants to send more money home than before.
Many governments are also trying to attract more people. Canada has an explicit target to welcome 1.5m new residents in 2023-25. Germany and India recently signed an agreement to allow more Indians to work and study in Germany.
Australia is increasing the time period some students can work after graduating from two to four years. Britain has welcomed Hong Kongers looking to flee Chinese oppression—well over 100,000 have arrived. Many countries have made it easy for Ukrainians to enter.
Even those countries hitherto hostile to migration, including Japan and South Korea, are looking more favourably on outsiders as they seek to counteract the impact of ageing populations.
Economies that welcome lots of migrants tend to benefit in the long run. Just look at America. Foreign folk bring new ideas with them.
In America immigrants are about 80% likelier than native-born folk to found a firm, according to a recent paper by Pierre Azoulay of the Massachusetts Institute of Technology and colleagues.
根据麻省理工学院的皮埃尔 · 阿祖莱(Pierre Azoulay)和他的同事们最近发表的一篇论文，在美国，移民成立公司的可能性比土生土长的人大约高出80% 。
Research suggests that migrants also help to build trading and investment links between their home country and the receiving one. A slug of young workers also helps generate more tax revenue.
Your people shall be my people
Some economists also hope that the wave of migration will have more immediate benefits.
“High immigration is helpful for the Fed as it tries to cool down the labour market and slow down inflation,” says Torsten Slok of Apollo Global Management, an asset manager, expressing a common view. Such arguments may be a little too optimistic.
资产管理公司阿波罗全球管理公司(Apollo Global Management)的托尔斯滕•斯洛克(Torsten Slok)表达了一个共同的观点: “大量移民有助于美联储为劳动力市场降温并减缓通胀。”。这些观点可能有点过于乐观了。
Having more people does increase the supply of labour, which all else equal reduces wage growth. But the effect is pretty small. There is little sign that the countries receiving the most migrants have the loosest labour markets.
In Canada, for instance, pay is still rising by about 5% year on year.
Migrants also increase demand for goods and services, which can raise inflation. In Britain new arrivals appear to be pushing up rents in London, which already had a constrained supply of housing. A similar effect is noticeable in Australia.
Estimates published by Goldman Sachs, a bank, imply that Australia’s current annualised net migration rate of 500,000 people is raising rents by around 5%. Higher rents feed into a higher overall consumer-price index.
Demand from migrants may also explain why, despite higher mortgage rates, house prices in many rich countries have not fallen by much.
Over the next year or so migration may come down a bit. The post-pandemic “catch-up” will end; rich-world labour markets are slowly loosening. Yet there is reason to believe that historically high levels of new arrivals will remain raised for some time.
More welcoming government policy is one factor. More important, migration today begets migration tomorrow, as new arrivals bring over children and partners. Before long the rich world’s anti-immigrant turn of the late 2010s will seem like an aberration.
