Using a quantitative spatial model as a data-generating process, we explore how spatial frictions affect the measurement of quality of life. We find that under a canonical parameterization, mobility frictions-generated by idiosyncratic tastes and local ties-dominate trade frictions- generated by...

Ein moderner und nachhaltiger Sozialstaat braucht eine gesunde Mischung aus staatlicher Fürsorge und Eigenverantwortung. Die Hartz-Reformen versuchten, die richtige Mischung mit dem Prinzip des Förderns und Forderns in der Grundsicherung herzustellen. Zahlreiche Menschen sind seither nicht...

Individual labour productivities are often unobservable for firms when hiring new workers. Job protection may prevent firms ex post from using information about labour productivities. We show that a binding minimum wage introduced in the presence of job protection will lead to lower unemployment...

Die Einführung des flächendeckenden gesetzlichen Mindestlohns von 8,50 Euro ist ein großes, mit vielen sozialpolitischen Risiken verbundenes Experiment. Dieser Übersichtsartikel zeigt, dass weder die unterschiedlichen theoretischen Erklärungsmodelle noch die große Anzahl empirischer...

A large literature has documented top income share series based on income tax statistics using the common methodology established by Piketty (2001, 2003). The disappearance of capital income from the income tax base in many countries poses a major challenge to the comparability of these series...

This paper examines the impact of tuition fees on graduation rates among high-school leavers. We analyse the introduction of fees in several German states in 2006-07 (around EUR 1,000 annually), using administrative microdata on all university graduates and a difference-in-differences approach....

We document a substantial gender gap in China's gender-blind university admissions system: equally qualified female students are less likely to apply and be admitted to elite universities than male students. Leveraging linked administrative and survey data on students' application choices,...

As social media becomes prominent within academia, we examine its reputational costs for academics. Analyzing Twitter posts from 98,000 scientists (2016-22), we uncover substantial political expression. Online experiments with 4,000 U.S. respondents and 135 journalists, rating synthetic academic...

The matching literature commonly rules out that market design itself shapes agent preferences. Underlying this premise is the assumption that agents know their own preferences at the outset and that preferences do not change throughout the matching process. Under this assumption, a centralized...
