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...

This paper studies the impact of immigration on public policy setting. We exploit the sudden arrival of eight million forced migrants in West Germany after WWII. These migrants were poorer than the local population but had full voting rights and were eligible for social welfare. We show that...

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...

This paper studies how a student's ordinal rank in a peer group affects performance and specialisation choices in university. By exploiting data with repeated random assignment of students to teaching sections, we find that a higher rank increases performance and the probability of choosing...

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...

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....

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,...

Global migration is heavily skill-biased, with tertiary-educated workers being four times more likely to migrate than workers with a lower education. In this paper, we quantify the global impact of this skill bias in migration. Based on a quantitative multi-country model with trade, we compare...

Welfare programs are important in terms of reducing poverty, although they create incentives for recipients to maximize their income by either reducing their labor supply or manipulating their taxable income. In this paper, we quantify the extent of such behavioral responses for the Earned...
