Studies have shown that ethnic discrimination occurs in many countries across Europe and the rest of the world, but distinguishing between discrimination based on ‘stereotypes’ and on ‘tastes’ is difficult. This column presents results from an experiment in the Netherlands that isolated taste-based discrimination. The results suggest that native Dutch participants reciprocate trust placed in them by immigrants of non-Western less than they reciprocate the trust of fellow Dutch natives. Since trustworthiness involves no behavioural risk, this implies that discrimination is the consequence of not only stereotyping, but also of tastes.

Stricter immigration and visa policies are a common reaction to terrorist attacks. This column uses historical data from 20 OECD countries to show that while the number of terror attacks increased with the number of foreigners living in a host country, migrants were not more likely to become terrorists than the locals of the country in which they were living. The results also show that bans on Muslim immigration would be more likely to increase the risk of terror than make the domestic population safer.

Recent empirical studies of the effects of immigration have tended to focus on short-run outcomes. This column considers the longer run by examining how mass migration at the turn of the 20th century has affected US outcomes today. Higher historical immigration between 1860 and 1920 is found to result in significantly better social and economic outcomes today. The results suggest that the long-run benefits of immigration can be large, can persist across time, and need not come at a high social cost.

Modern Italy has more inter-ethnic marriages – a consequence of recent immigration. This column uses recent census data to show that  inter-ethnic marriages in Italy have a significantly higher risk of separation, which persists even when accounting for spousal traits and self-selection. The difference is smaller for recent marriages, reflecting a more secular society.

Israel has received almost one million immigrants from the former Soviet Union, close to 19% of its established population. The extraordinary exodus of Soviet Jews to Israel in the 1990s is relevant to the current debate about globalisation. This column argues that the wave of immigration was distinctive for its large high-skilled cohort and its quick integration into the domestic labour market. Soviet-Jew immigration raised productivity, underpinned technological prowess, and had a large impact on income inequality and redistribution in Israel’s welfare state.

There has been a surge of anti-immigrant sentiment in the US and many European countries. This column uses survey results to show that accurate information about numbers of immigrants changes opinions on whether there are too many immigrants, but not on policy towards them. More detailed information on the characteristics of immigrants, however, can increase support for pro-immigrant policies, particularly among those who start off with the most negative views on immigration.

Diverse countries tend to have more conflict, lower development, and worse public goods, possibly due to antagonism between groups. Based on recent research mapping local linguistic diversity across the entire globe, this column argues that local interaction with people of other ethnolinguistic groups can mitigate the negative effect of overall diversity on a country’s outcomes in health, education and public goods. This finding lends support to policies that influence the local mixing of ethnolinguistic groups.

Despite numerous studies exploring how immigration affects local labour markets, there is limited evidence on the impact of immigrants on firms’ productivity levels. Using detailed, firm-level data from France, this column explores how firms react to an increase in the supply of immigrant workers. Provinces with a large increase in immigrant supply experienced higher productivity growth, especially among firms that were initially less productive. This suggests immigration can promote convergence in firm size and productivity levels.

The distribution of talent and human capital is highly skewed across the world. As high-income countries engage in a global race for talent, the resulting migration of high-skilled workers across countries tilts the deck even further. This column draws upon newly available data to outline the patterns and implications of global talent mobility. Key results include recent dramatic increases in high-skilled migration flows, particularly in certain occupations, in certain countries, among those with higher skill levels, and from a wider range of origins.

Far-right parties have made considerable electoral gains around the world lately, fuelled in part by strong anti-immigration rhetoric. This column presents the results of an experiment conducted in Japan to assess whether exposure to positive information about immigration can decrease this public hostility. Such information exposure is found to increase an individual’s likelihood of supporting immigration by between 43% and 72%. This suggests that information campaigns are a very promising avenue for policymakers aiming to redress hostility to immigration.

The macroeconomic effects of immigration are a hot topic, particularly during elections. Using immigration records from Norway, this column argues that an increase in immigration lowers unemployment (even for native workers) and has no negative effects on public finances. However, it identifies a negative effect on productivity that may be a worry for long-term growth.


The aim of the conference is to reflect on the limits of current data used to study migration and to connect producers and academic users of migration data. The organizing committee invites the submission of high-quality academic papers that use different datasets (administrative, survey, experimental). A roundtable will be organized with stake-holders that facilitate data collection and dissemination (DGEF, IAB, INED, OECD).

Key note speaker: Herbert BRÜCKER (University of Bamberg, IAB, IZA) “Causes and consequences of refugee migration: new evidence from the German refugee survey”

If you would like to submit a paper please send an email to [email protected]. In the case of multiple-authored papers, indicate who will present and whether or not the presenter would also be willing to act as a discussant. Authors will be notified about the acceptance of papers and the conference programme by the end of March, 2017.

Recent political events have highlighted a growing anti-globalisation sentiment, evident in scepticism towards free trade and resistance to immigration. However, existing analyses focus on short-term, local effects. Using global data, this column takes account of the complex relations between trade, migration, innovation, and growth. Liberal trade and immigration stances are found to have positive effects on global output. The results suggest that globalisation remains a tremendously powerful engine of growth.

There is much dispute over whether immigration is beneficial or detrimental to the host country, and any conclusions are often event-driven rather than evidence-based. This column explores evidence on how immigration affected economic development between 1960 and 2013 through its effect on the cultural and ethnic composition of the destination country. Cultural heterogeneity appears to have had a positive impact on economic development, and the positive effect of diversity seems to have been stronger in developing countries.

At first glance, the migration pressures on the EU and US appear similar, but recent history is not a reliable guide to future trends. This column uses demographic trends to predict that the US will experience a gradual decline in its newly arrived immigrant population, while the EU, ringed by nearby high-population-growth states, will see large increases in the stock of first-generation immigrants. As a result, US emphasis on strengthening borders and returning undocumented migrants may be misplaced.

The economic effects of the unprecedented levels of international migrations over the past few years are at the centre of political debates about immigration policy. This column evaluates the causal effect of migration on foreign direct investment using immigration patterns to the US going back to the 19th century. Foreign direct investment is found to follow the paths of historical migrants as much as it follows differences in productivity, tax rates, and education. The results suggest a mechanism of information flow facilitation, and that the effect of ancestry on foreign direct investment is very long-lasting.

The migration debate is often harsh and polarised, oscillating from calls for more open borders to promises to build new fences, and contrasting the views of those who emphasise the advantages and benefits from migration flows with those who consider migrants to impose an unnecessary strain on hosting societies. This column introduces a new eBook that offers a brief summary of what economists have learnt about migration in several crucial areas of policymaking, and identifies most of the important questions that still remain to be answered.

Upward social mobility is widely sought but often elusive in highly mobile societies like the US. While previous work has focused on intergenerational transmission of income levels and social prosperity among natives and immigrants, this column studies the intergenerational transmission of health. There is substantial persistence in health status for both natives and immigrants. However, as immigrant families remain in the US for more generations, their children’s health tends to resemble more the health of native children and less the health of their mothers.
