Immigrants to the US are drawn from both ends of the education spectrum. This column looks at the effect of highly educated immigrants – in particular, those with degrees in Science, Technology, Engineering, or Mathematics – on total factor productivity growth. The authors find that foreign STEM workers can explain 30% to 60% of US TFP growth between 1990 and 2010.

Social norms have been shown to have important effects on economic outcomes. This column discusses new evidence showing that social norms are deeply rooted in long-standing cultures, but do evolve in reaction to major changes. It draws on a fully global sample involving migrants in more than 130 countries, using seven waves of the Gallup World Poll.

The immigration debate has focused on immigrants’ net fiscal impact – whether they receive more in welfare payments and other benefits than they pay back in taxes. This column summarises research showing that – contrary to popular belief – immigrants who arrived in the UK since 2000 have contributed far more in taxes than they have received in benefits. Compared with natives of the same age, gender, and education level, recent immigrants are 21% less likely to receive benefits.

Are children who are non-native speakers making education worse for native speakers? Presenting new research on England, this column uses two different research strategies showing that there are, in fact, no spillover effects. These results support other recent studies on the subject. The growing proportion of non-native English speakers in primary schools should not be a cause for concern.

Elderly people assisted by immigrant carers, rather than by their sons and daughters, has become a common feature of many European countries. This column presents evidence from Italy suggesting that the immigrant presence in the home-care sector has allowed women, especially those with elderly parents, to retire from their jobs later. Increasing the retirement age has to happen over the coming decades to ensure the sustainability of developed countries’ pension systems.

In the US, fewer and fewer people are moving long distances to pursue job opportunities. Presenting new research on Mexican immigrants in the US, this column argues that there are large welfare gains from the efficient spatial allocation of labour. However, welfare gains from the movement of labour are woefully understudied. If immigrants are more willing to move for a job than natives, policymakers should allow them to do so with ease. Workers should be free to move to markets offering better opportunities.

Some European media have expressed concerns that the presence of immigrant children in schools may reduce the educational outcomes of native children. Analysing data from the Netherlands, this column finds that after controlling for differences within schools, the educational achievement of native children is almost completely unaffected by the presence of immigrant children.

Migration policy is a pressing issue, but our empirical understanding of it is wanting. This column introduces new estimation techniques for identifying the impact of immigration policies. The novelty is to account for third-country effects since migrants have more options than staying home and moving to the hoped-for destination. Looking at bilateral policies in isolation misses this externality. Disregarding such ‘multilateral resistance to migration’ leads to an underestimation of the effect of bilateral migration policies, and thus potentially leading to severe policy mistakes.

Does emigration create a brain drain or – as commentators have recently been suggesting – do diasporas in fact represent a net brain gain? This column argues that if sending countries can protect intellectual property rights, they will foster the necessary diaspora knowledge networks to significantly help economic development in sending countries.

Are poorly-educated immigrants’ kids dragging native classmates down? Or do schoolchildren push themselves when new, smarter immigrants join their class? This column argues that although child immigrants may sometimes bring down native minorities, on the whole, poorly educated natives upgrade their education in response to new immigrants in the classroom.

Europe is experiencing an unprecedented inflow of immigrants. Casual observation suggests that far-right parties could benefit from voters’ worries about this inflow. This update to a column from September 2012 provides empirical evidence showing that the geographic proximity of immigrants is one important causal driver behind support for the far right. The link with voting outcomes depends on the type of immigration, however, not just on the total number of immigrants.

Andrés Rodríguez-Pose, Viola Von Berlepsch, 02 September 2012

This paper examines the extent to which the distinct settlement pattern of migrants arriving in the US during the big migration waves of the late 19th and early 20th centuries has left a legacy on the economic development of the counties where they settled and whether this legacy can be traced until today.

How does radical Islamic terrorism impact Muslim immigrants in the West? The backlash against Muslims in the US after the terrorist attacks of 9/11 damaged assimilation among Muslim immigrants, argue the authors of CEPR DP8797 – and they present strong evidence to prove it.

Lobbying is a primary avenue through which firms attempt to change policy. But only a few big firms lobby and lobbying is highly persistent over time. This column argues that entry costs to the political process help explain these facts. It provides evidence from a change in immigration policy that induced firms that were already lobbying and were sensitive to the policy changes to switch from lobbying on other issues towards immigration while other firms did not enter the lobbying process.

This week the world population is projected to reach seven billion. Yet in some countries the prospect of a decline in population is worrying policymakers far more. This columns asks what the people think, focusing on a survey from the Netherlands. It turns out that most people are in favour of global population decline, but “not in my backyard”.

Migration is an issue not helped by misleading statistics and poor data. This column presents a study bringing together over 1,000 national censuses and population registers for 226 countries and regions between 1960 and 2000.

Paul Romer, 10 June 2011

Paul Romer of NYU’s Stern School of Business talks to Romesh Vaitilingam about his vision of dysfunctional poor countries kick-starting their own development by creating new cities with new rules – what he calls ‘charter cities’. The interview was recorded in London in June 2011 at a ‘blue-sky’ conference on development policy-making organised by CAGE, the Centre for Competitive Advantage in the Global Economy at the University of Warwick.

Mass international migration is inherently controversial. This column looks at how the US immigration policies before 1914 sought to manage mass migration across the North Atlantic. It suggests that, with migration today seemingly neither well-controlled nor well-managed, the managed laissez-faire approach of a century ago is regaining relevance.

The recent surge of refugees entering Europe from North Africa – particularly through Lampedusa – has caused a rift among EU states over what should be done and who should shoulder the responsibility. This column asks what theory and recent history can tell us about sharing the refugee burden in the EU.

Assaf Razin, Jackline Wahba, 04 March 2011

Do immigrants just move for the benefit systems? This column argues that the effect of the welfare state on immigration and its composition depends on whether the destination country's migration policy is “free” or “managed”, and on whether the source country is developed or developing.
