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...

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 the long-term effect of radiation on cognitive skills. We use regional variation in nuclear fallout caused by the Chernobyl disaster in 1986, which led to a permanent increase in radiation levels in most of Europe. To identify a causal effect, we exploit the fact that the...

This paper studies the impact of immigration on public policy setting. As a natural experiment, we exploit the sudden arrival of eight million forced migrants in West Germany after World War II. These migrants were on average poorer than the West German population, but unlike most international...

Does poor air quality affect decision-making? We study this question based on elections, in which millions of people decide on the same issue on the same day in different locations. We use county-level data from 64 federal and state elections in Germany over a nineteen-year period and exploit...

A commonly expressed concern about immigration is that it undermines social cohesion in the receiving country. In this paper, we study the impact of a large and sudden inflow of asylum seekers on several indicators of social cohesion. In 2015/16, over one million asylum seekers from Syria,...

Welfare programs are important for reducing poverty but create incentives for recipients to maximize their income by either reducing labor supply or manipulating taxable income. In this paper, we quantify the extent of such behavioral responses for the Earned Income Tax Credit (EITC) in the US....
