Im Mittelpunkt steht die ungeplante Zuwanderung Geflüchteter in den Jahren 2015/16. Die Untersuchung konzentriert sich auf Deutschland, erforscht aber auch den breiteren europäischen Kontext. Erkenntnisse aus Mehrebenenanalysen, Längsschnittdaten und exklusiv erhobenen Geodaten ...
Pre-vaccine SARS-CoV-2 seroprevalence data from Germany are scarce outside hotspots, and socioeconomic disparities remained largely unexplored. The nationwide representative RKI-SOEP study (15,122 participants, 18–99 years, 54% women) investigated seroprevalence and testing in a supplementary wave of the Socio-Economic-Panel conducted predominantly in October–November 2020. Self-collected oral-nasal ...
This paper investigates the dynamic effects of tax changes on the cross-sectional distribution of disposable income in the United States using a narrative identification approach. I distinguish between changes in personal and corporate income taxes and quantify the distributional effects on families and business owners. I document that tax changes affect incomes along the distribution differently and ...
This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions ...
In response to strong revenue and income losses that a large share of the self-employed faced during the COVID-19 pandemic, the German federal government introduced a €50bn emergency aid program. Based on real-time online-survey data comprising more than 20,000 observations, we analyze the impact of this program on the subjective survival probability. In particular, we investigate how the digitalization ...

While mothers using centre-based care spend significantly less time in the presence of their child, we find that differences in the time spent on specific activities such as reading, talking, and playing with the child are relatively small or zero. The pattern of results ...
