In the 20th century at least 6 million African Americans migrated from poor southern states to northern cities to escape discrimination and poverty, changing the course of American history. At least as many whites also migrated, taking their ideas with them. Samuel Bazzi tells Tim Phillips that they have also influenced social structures and politics in the US.

The capacity of workers to move regions in response to local economic shocks is a key dimension of labour market dynamism that could contribute to recovery from the COVID-19 crisis and support the green transition. This column presents new empirical evidence on how policies can shape the responsiveness of inter-regional migration to regional economic conditions, with a particular focus on housing markets, social policies, and business regulations. It highlights the need for articulating place-based policies to help prospective movers as well as stayers.

Less than half of all applicants for political asylum in Europe gain some form of recognition that allows them to stay. Since the early 2000s, the EU has developed a common asylum policy with the aims of protecting the rights of refugees and mitigating the ‘asylum lottery’.  This column shows that the implementation of EU Directives contributed modestly to an overall increase in average recognition rates but has not reduced the variation in rates across countries.

What are the gains for workers from moving from a poor economy to a rich one? This column examines this question using the case of Palestinian workers who could decide to either work in the (poorer) local economy or commute to work in (richer) Israel. It finds productivity gains experienced by the migrants are largely offset by the low returns for the job tasks offered to these migrants in the richer economy.

Labour mobility is a key criterion for assessing optimum currency areas. To smooth country-specific shocks or business cycles in currency unions, it is key that people migrate across the countries or regions of the union. This column argues that the ongoing discussion about risk sharing in the euro area neglects the issue of labour mobility. Relative to the US, migration rates in the euro area are significantly lower and migration contributes less to overall risk sharing. It calls for a renewed focus on the principle of labour mobility in order to enhance risk sharing in the euro area.

Trade restrictions are often invoked as a way to stem climate change. Although international transportation is an important source of carbon emissions, this view is incomplete. Using a dynamic spatial growth model, this column argues that trade can be a powerful mechanism to adapt to rising temperatures. The interaction of climate change, productivity, and migration decisions gives rise to significant global changes in populations and sectoral specialisations. On aggregate, rising temperatures are predicted to lower real GDP per capita by 6% and welfare by 15% by the year 2200.

Despite potentially greater income gains in big cities, migrants from rural areas in developing countries often move to small towns. This column uses survey data from Tanzania to show that distance drives destination in migration decisions, particularly for the poor and for those with no education. This finding explains the seeming paradox of greater migration to small towns than to big cities, and provides a strong argument for a more balanced orientation of development investment between the two.

The COVID-19 pandemic has led to a dramatic rise in protectionism and restrictions around the world. This column sheds light on the role migration can play in restoring globalisation in the wake of COVID-19. It draws upon evidence from macro-, sub-national, and micro-level research to demonstrate that migration has the potential to promote economic recovery through facilitating foreign trade, investment, and offshoring. The findings carry implications not only for physical migration, but also for whether or not recent technological advances may enable foreign-based online workers to promote globalisation.

Why do workers remain in low-productivity areas when they could experience wage gains elsewhere? While the literature has proposed a few explanations, including the high cost and risky nature of migration, this column uses the case of China to examine instead the role that pollution plays. It finds that severe pollution can induce workers to relocate from productive to unproductive regions, suggesting that pollution control, coupled with policies facilitating migration, has the potential to bring about extra economic gains in developing countries.

The recent refugee crisis has fuelled discussions about policies restricting immigration. This column quantifies the extent to which asylum policies affect emigration by analysing the migration decisions of German Jewish refugees in the 1930s. Policies have large effects on migration as the effects are multiplied through peers who influence each other in the decision to emigrate. Removing work restrictions for refugees in the recipient countries after the Nuremberg Laws in 1935 would have led to a 28% increase in Jewish emigration out of Germany.

Alcohol is one of the leading killers among substances, but little is known how various factors interact to affect individual alcohol consumption. This column explores how much the environment –, including supply conditions, alcohol regulation, taxes, and peers – drives alcohol consumption, by analysing changes in alcohol purchases when US consumers move from one state to another. The current environment explains about two-thirds of the differences in alcohol purchases, with consumers’ alcohol purchases converging sharply toward the average purchase level in their destination state right after moving.

Immigration policy has become a hot-button issue in both Europe and the US, with questions concerning optimal policy as well as the welfare state dominating discussions. This column revisits the idea of the immigration surplus, exploring a number of possible scenarios in terms of how policymakers should address the challenge. Correctly configuring fiscal policy so as to capture the benefits of both high- and low-skill immigrant (and native) workers is at the heart of optimal policy design and may help to address the swelling anti-immigrant sentiment that continues to exist in many countries today.

Many internal migrants returned to their place of origin after the initial outbreaks of COVID-19 and before national lockdowns were in place. Has this behaviour contributed to the further spread of the pandemic and to its heavy death toll? Looking at the case of Italy and using data on the place of origin and destination of internal migrants, this column finds that provinces more exposed to return migration from areas hit by the pandemic earlier on experienced considerably more COVID-19 deaths in the ensuing months.

Urbanisation is a major driver of economic development. Agglomeration forces that make cities productive and dispersion forces that limit their growth have been extensively studied, but the effect of ethnolinguistic diversity has been largely overlooked. This column shows that more diverse regions tend to experience more social tensions and conflict, less urbanisation, less urban concentration, and hence potentially less economic growth. This effect is however more confined to intermediate political regimes like fragile democracies, whereas a mature degree of democracy helps to defuse the negative impact of diversity on urbanisation.

The COVID-19 pandemic has brought to light how much societies rely on migrants for key labour while highlighting the vulnerabilities of already weaker groups. Easing the socio-economic integration of migrants is beneficial to both migrants and host countries; yet, many European countries ban asylum seekers from legal employment upon arrival. This column examines the effect of such employment bans. The bans have large and lasting negative effects on refugees’ future labour-market integration and constitute an economic loss for the host country. Allowing early labour market access is an easily implementable and financially costless policy that effectively accelerates refugee integration.

The impact of the 2015 refugee crisis on sending and receiving societies has received significant scholarly attention. But there is little research on how the crisis affected ‘transit countries’ through which migrants travelled. This column studies 800 localities in 18 European countries to discover how local populations responded to the temporary presence of forced migrants. Data show that entrepreneurial activity of residents living closer to refugee routes fell considerably, and while anti-migrant sentiment increased in these areas, attitudes towards other minorities remained unchanged.

The procedures for relocating forced migrants differ considerably across countries, and information about how resettlement locations within host countries affect integration outcomes remains scarce. And yet, the number of forced migrants around the world increased dramatically over the last decade and continues to grow. This column studies displaced Germans after WWII and finds they fared poorly when relocated to agrarian regions with high migrant density. The authors recommend that current resettlement policies avoid directing large concentrations of migrants to a limited selection of rural areas.

From the 16th to the early 19th century, coastal areas of Italy (especially in the south-west) were subject to attacks by pirates launched from the shores of northern Africa. To protect themselves, residents of coastal locations moved inland to mountainous and rugged areas. This column shows how relocation constrained local economic development for a long period after the piracy threat had subsided and may have had aggregate consequences on Italy’s post-WWII development.

Small EU states regularly sell 'golden passports' to high net worth individuals, and these citizens thus earn the right to live and work anywhere in the EU. By imagining member states as private clubs and the EU as a ‘meta-club’, this column presents a model of the effects of this activity. While selling golden passports may be seen as an informal transfer to poorer states, the number of citizenships granted will always be larger than is optimal for the EU as a whole.

There is considerable historical and contemporary evidence of the linkages between skilled migration and innovation, suggesting that one of the most important engines of economic growth stands to be strongly negatively affected by the growing backlash against migration around the world. Based on a 95-country sample spanning several decades, this column shows that migrant inventors play an important role in shaping the patent production of their destination countries. Arguably, these dynamics – driven by migrant inventors – can also affect broader economic outcomes, given the secondary effects of patenting and innovation on productivity and firm performance.
