One of the fundamental questions in the social sciences is whether modern welfare states can be sustained as countries welcome more immigrants. On theoretical grounds, the relationship between immigration and support for redistribution is ambiguous. Immigration may increase ethnic diversity,...

The enlargement of the European Union in 2004 caused a large migration wave from Central Europe to Ireland and the UK. This paper addresses the question whether such an emigration wave changes the wage distribution in the source country. In a theoretical model of a labor market I show that some...

We study the impact of a student's ordinal rank in a high-school cohort on educational attainment several years later. To identify a causal effect, we compare multiple cohorts within the same school, exploiting exogenous variation in cohort composition. We nd that a student's ordinal rank in...

We study the impact of a student's ordinal rank in a high school cohort on educational attainment several years later. To identify a causal effect, we compare multiple cohorts within the same school, exploiting idiosyncratic variation in cohort composition. We find that a student's ordinal rank...

In this paper we show that a student's ordinal rank in a high school cohort is an important determinant of engaging in risky behaviors. Using longitudinal data from representative US high schools, and exploiting idiosyncratic variation in the cohort composition within a school, we find a strong...

How migration affects labor markets in receiving countries is well understood, but less is known about how migration affects labor markets in sending countries, particularly the wages of workers who do not emigrate. Most studies find that emigration increases wages in the sending country but...

Migrants are typically self-selected from the population of their home country. While a large literature has identified the causes of self-selection, we turn in this paper to the consequences. Using a combination of non-parametric econometrics and calibrated simulation, we quantify the impact of...

Diaspora networks provide information to future migrants and influence both their decision to migrate and their success in the host country. While the existing literature explains the effect of networks on migration decisions through the size of the migrant community, we show that the quality of...

High-skilled workers are four times more likely to migrate than low-skilled workers. This skill bias in migration – often called brain drain – has been at the center of a heated debate about the welfare consequences of emigration from developing countries. In this paper, we provide a global...

This paper studies how a student's ordinal achievement rank affects performance and specialization choices in university. We exploit data from a setting where students are randomly assigned to teaching sections and find that students with a higher rank in their section achieve higher grades,...
