German Emigration and Remigration Panel Study (GERPS): Documentation of the Third Wave

International migration originating from highly developed countries is a crucial component of global migration flows. There are, however, surprisingly little data about the international mobility of the populations of affluent countries. The German Emigration and Remigration Panel Study (GERPS) aims to provide a resource that enables the analysis of individual consequences of international migration ...

Estimating regional income indicators under transformations and access to limited population auxiliary information

Spatially disaggregated income indicators are typically estimated by using model-based methods that assume access to auxiliary information from population micro-data. In many countries like Germany and the UK population micro-data are not publicly available. In this work we propose small area methodology when only aggregate population-level auxiliary information is available. We use data-driven transformations ...

Why do immigrants become less happy? Explanations for the decrease in life satisfaction of immigrants in Germany over time

We investigate the life satisfaction (LS) trajectories of immigrants in Germany. Using data from the German Socio-Economic Panel from 1984 to 2015, we find that recently arrived immigrants are more satisfied with their lives than comparable German natives. However, their LS decreases more over time than that of their German counterparts; that is, we observe a negative years-since-migration (YSM)–LS ...

From low emission zone to academic track: Environmental policy effects on educational achievement in elementary school

Umweltzonen verringern die lokale Luftverschmutzung, indem sie emissionsintensive Fahrzeuge von der Zufahrt zu den ausgewiesenen Gebieten abhalten und nachweislich die Gesundheit der Bevölkerung verbessern. Über die Auswirkungen von Fahrverboten auf andere Lebensbereiche ist wenig bekannt. Dieses Papier untersucht die Auswirkungen von Umweltzonen auf die schulischen Leistungen von Grundschülern in ...

Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty

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 ...

Universal, targeted or both: Effects of different child support policies on labour supply and poverty - A simulation study

Wir untersuchen hypothetische Reformen der wichtigsten Transferleistungen für Kinder in Deutschland: eine Reform des nicht bedarfsgeprüften Kindergeldes, eine Reform der Kinderregelbedarfe im Rahmen der Grundsicherung und eine Kombination aus beiden Leistungen. Mit Hilfe eines statischen Steuer-Transfer Mikrosimulationsmodells (IAB-MSM), das auch endogene Arbeitsangebots- und Inanspruchnahmeentscheidungen ...

A developmental perspective on personality–relationship transactions: Evidence from three nationally representative samples

Objective: Throughout their lives, people experience different relationship events, such as beginning or dissolving a romantic relationship. Personality traits predict the occurrence of such relationship events (i.e., selection effects), and relationship events predict changes in personality traits (i.e., socialization effects), summarized as personality–relationship transactions. So far, evidence ...

ZEW-EviSTA: A Microsimulation Model of the German Tax and Transfer System

This article describes ZEW-EviSTA®, the microsimulation model developed and used at ZEW - Centre for European Economic Research in Mannheim. The model simulates the German tax and transfer system using household micro level data. By estimating fiscal effects, labor market outcomes as well as distributional impacts the model allows for a comprehensive ex ante analysis of reform proposals. Heterogeneity ...
