Immigration has become a central driver of U.S. labor force growth. We document new empirical findings that shed light on the relationships between immigration, labor shortages, wage growth, and job openings during the high-immigration period of 2021-2024. The textbook search-and-matching model...

This paper estimates the causal impact of Brexit on migrant employment in the United Kingdom using a synthetic difference-in-differences (SDID) framework. We construct a counterfactual trajectory for the UK based on a weighted combination of comparable European economies and compare...

The educational distribution of U.S. immigrants shifted significantly to the right in recent decades as the share without a high school diploma fell and the share with a bachelor's degrees rose. This improvement coincided with a shift in immigrants' origins toward Asia and rising global...

The H-1B program lets firms hire high-skill foreign workers for a six-year term. The annual number of visas allocated to for-profit firms is capped at 85,000 and there is excess demand for those visas. The analysis merges administrative data, including the I-129 petitions that report the wage...

This open access short reader provides an introductory yet critically analytical exploration of migration and the politics of integration. Drawing inspiration from Nira Yuval-Davis' concept of the 'politics of belonging,' we define the 'politics of integration' as various political projects...

his paper investigates how immigration affects consumer prices. Using scanner data and instrumenting county-level immigration with historical ancestry patterns, we find that an inflow of 10,000 immigrants lowers four-year price growth by 0.58 percentage points. Leveraging variation in firm...

There are relatively few comparative cross-European studies on segregation, and those that do exist often use a single measure of segregation at a single spatial scale. This paper investigates ethnic segregation in seven European capitals - Amsterdam, Berlin, Lisbon, London, Madrid, Paris, and...

This paper studies the impact of birthright citizenship on youth crime. We leverage a reform which automatically granted birthright citizenship to eligible immigrant children born in Germany after January 1, 2000 and administrative crime data from three federal states. Immigrant youth who...

This paper examines how declining migration opportunities to the United States affect local labor markets in Mexico. Using novel micro-level data from consular identification cards and deportations, we link individuals’ Mexican municipalities of origin to their U.S. destination states. We...

Immigration was central both to the 2016 Brexit referendum campaign and to the political narratives that followed it. Yet the trajectory of migration to the UK since the referendum bears little resemblance to the expectations - or promises - articulated at the time. This paper provides an...

This paper studies the causal impact of language skills on human capital accumulation, labor market outcomes, and job characteristics of childhood immigrants across European countries. Using PIAAC data, we adopt an instrumental variable strategy based on the critical age hypothesis and...

The US government in 2025 imposed a $100,000 tax on each high-skill foreign worker entering with an H-1B work visa. The only public economic justification calculates the tax to offset an estimated wage penalty for H-1B workers relative to US natives. But this estimate suffers from substantial...

This paper shows that immigrants not only have differential effects on trade based on their skill levels but that they play an additional role in facilitating bilateral trade if their origin country has a higher level of corruption and weaker institutions. Using immigrant stock across skill...

Immigrants across Europe earn less and work in lower-quality jobs than natives, but the mechanisms underlying these disparities remain poorly understood. This paper asks whether immigrant disadvantage reflects barriers to accessing good jobs or skill deficits that persist even within similar...

Many couples face a trade-off between advancing one spouse's career or the other's. We study this trade-off using administrative data from Germany and Sweden. Using an event study approach, we find that when couples move across commuting zones, men's earnings increase more than women's. To...

We provide causal evidence that immigration has contributed to the polarization of American politics. Using an ancestry-based shift-share instrument, we study immigration flows into U.S. counties between 1992 and 2016. Counties exposed to larger immigrant inflows become more polarized both in...

Do factual immigration updates shift societal concerns across political ideologies? Conducting an online experiment in the lead-up to the 2024 U.S. Presidential Election, respondents provided local immigrant stock and flow estimates before being randomized to receive realistic information on...

This paper studies the impact of birthright citizenship on youth crime. We leverage a reform which automatically granted birthright citizenship to eligible immigrant children born in Germany after January 1, 2000 and administrative crime data from three federal states. Immigrant youth who...

Objective: The article aims to analyse the key determinants of multiple dimensions of economic integration among Ukrainians in Poland, including employment status, job quality, skill matching, job satisfaction, and perceived financial situation, with a comparison between forced and economic...

Using the quasi-random allocation of refugees and detailed administrative data, we examine the effect of urban density on refugees' decisions to naturalise. Our results indicate that refugees assigned to urban areas are more likely to naturalise, largely due to a higher density of co-national...

The impact of sudden asylum seeker inflows on host residents' mental health is largely unexplored. The present study addresses this research gap and provides the first causal evidence from the non-Western context by exploiting the unexpected influx of Yemeni asylum seekers to Jeju Island, South...

Migration scholars commonly study international migration and socio-economic integration separately, typically focusing on a single receiving country in the Global North. The TRANSMIT project adopts a transnational perspective, studying key migration routes to Europe via large-scale surveys...

We evaluate a two year school development program aimed at enhancing the quality of education for recent migrant students and Swedish language learners through customized packages of professional development for teachers and support of school man-agement. We exploit the pairwise randomized roll...

The educational distribution of U.S. immigrants shifted significantly to the right in recent decades as the share without a high school diploma fell and the share with a bachelor's degree rose. This improvement coincided with a shift in immigrants' origins toward Asia and rising global education...

We exploit the sharp escalation in community-based ICE enforcement following the January 2025 inauguration to estimate the causal effect of immigration enforcement on consumer spending. Using Synthetic Difference-in-Differences with cross-state variation in surge intensity as the identifying...

The paper provides a descriptive analysis of both the early impacts of COVID on business activity among immigrants and the economic recovery over the next few years. The findings indicate that immigrant business owners were disproportionately affected by COVID in the first month of the pandemic...

First-generation immigrants face a seniority ceiling that limits their political incorporation as candidates and officeholders. Career ladders that require qualification time in lower positions create structural barriers for this group. We use linked data from Swedish electoral ballots and...

Using matched employer-employee data on more than 62,000 master's graduates, this paper examines how gender differences in wage returns to fields of study vary by migration background and how educational specialisation contributes to the gender wage gap. We estimate wage regressions and apply a...

Following reunification, anti-foreigner crimes rose sharply in the former GDR. Using countylevel data for the early 1990s, we study if regional access to Western TV, i.e. non-socialist media, prior to the fall of the Berlin Wall had an impact on regional levels of serious antiforeigner crime...

Using matched employer-employee data on more than 62,000 master's graduates, this paper examines how gender differences in wage returns to fields of study vary by migration background and how educational specialisation contributes to the gender wage gap. We estimate wage regressions and apply a...

I estimate the causal impact of the US Secure Communities (SC) program, which expanded deportation risk nationwide, on Hispanic suicide rates. Using the staggered county rollout (2008-2013) and a triple difference-in-differences design, I identify heterogeneous effects relative to non-Hispanic...

Out-migration is a common feature of rural life in the Global South, yet its effects on social networks in origin communities remain underexplored. Drawing on original data from nearly 10,000 households in 145 villages in Senegal, this paper presents observational evidence linking household...
