Inspections and Compliance: Enforcement of the Minimum-Wage Law

This paper is the first to empirically study the relationship between spatial distributions oflabor market inspections and noncompliance with Germany’s minimum-wage law. Combiningnovel administrative data with large-scale longitudinal survey data, we documentthat the inspection probability is higher in regions with higher noncompliance. This impliesrisk-based allocation of the inspection efforts and, ...

Limited Self-knowledge and Survey Response Behavior

We study response behavior in surveys and show how the explanatory power of self-reports can be improved. First, we develop a choice model of survey response behavior under the assumption that the respondent has imperfect self-knowledge about her individual characteristics. In panel data, the model predicts that the variance in responses for different characteristics increases in self-knowledge and ...

SOEP-RV: Linking German Socio-Economic Panel Data to Pension Records

The aim of the project SOEP-RV is to link data from participants in the German Socio-Economic Panel (SOEP) survey to their individual Deutsche Rentenversicherung (German Pension Insurance) records. For all SOEP respondents who give explicit consent to record linkage, SOEP-RV creates a linked dataset that combines the comprehensive multi-topic SOEP data with detailed cross-sectional and longitudinal ...

So funktioniert die “Weisheit der vielen” wirklich - Gert G. Wagner über Schwarmintelligenz in der Wissenschaft

Nicht Genies, sondern die Arbeit vieler einzelner Forscher entscheidet über wissenschaftlichen Fortschritt. Allerdings nur, wenn bestimmte Bedingungen erfüllt sind. Die Wissenschaft hat nun einen Weg gefunden, die Weisheit der vielen für sich zu nutzen. Dieser Artikel erschien am 10. August 2021 als Gastbeitrag in der WELT. Es ist immer wieder mal die Rede von Schwarmintelligenz, die ...

Discounting Behavior in Problem Gambling

Problem gamblers discount delayed rewards more rapidly than do non-gambling controls. Understanding this impulsivity is important for developing treatment options. In this article, we seek to make two contributions: First, we ask which of the currently debated economic models of intertemporal choice (exponential versus hyperbolic versus quasi-hyperbolic) provides the best description of gamblers’ discounting ...

Extending the Kitagawa–Oaxaca–Blinder Decomposition Approach to Panel Data

The Kitagawa–Oaxaca–Blinder decomposition approach has been widely used to attribute group-level differences in an outcome to differences in endowment, coefficients, and their interactions. The method has been implemented for Stata in the popular oaxaca command for cross-sectional analyses. In recent decades, however, research questions have been more often focused on the decomposition of group-based ...

Scoring ist nicht neu, sondern uralt: Aus seiner Geschichte kann man lernen, wie man heutzutage damit umgehen kann und soll

On the Right Track? – The Role of Work Experience in Migrant Mothers’ Current Employment Probability

This paper investigates the role of work experience in migrant mothers’ current employment in Germany. Unlike previous papers, we focus on actual experience and add the motherhood aspect. To this end, we use data from the German Socio-Economic Panel 2013-2018 including the IAB-SOEP Migration Sample. Having immigrated to Germany and female sex are the two treatments of our sample of 491 migrant mothers, ...

Panel Data in Research on Mobility and Migration: A Review of Recent Advances

Panel data has become the gold standard for causal assessments of complex human behaviour in quantitative social science. The objective of this review is to examine and discuss how panel data and related methods contribute to the identification of causal relationships in spatial mobility research. We illustrate this by providing a succinct overview of recent progress in spatial mobility research, drawing ...

De-routinization of Jobs and Polarization of Earnings: Evidence from 35 Countries

The job polarization hypothesis suggests a U-shaped pattern of employment growth along the earnings/skill distribution, which is driven by simultaneous growth in the employment of high-skill/high-earnings and low-skill/low-earnings occupations due to Routine-Biased Technological Change (RBTC) [Acemoglu and Autor, 2011]. An aspect of both high social and political relevance is the implications of job ...

COVID-19: a Crisis of the Female Self-Employed

We investigate how the economic consequences of the pandemic and the government-mandated measures to contain its spread affect the self-employed — particularly women — in Germany. For our analysis, we use representative, real-time survey data in which respondents were asked about their situation during the COVID-19 pandemic. Our findings indicate that among the self-employed, who generally face a higher ...

2D:4D Does Not Predict Economic Preferences: Evidence from a Large, Representative Sample

The digit ratio (2D:4D) is considered a proxy for testosterone exposure in utero, and there has been a recent surge of studies testing whether 2D:4D is associated with economic preferences. Although the results are not conclusive, previous studies have reported statistically significant correlations between 2D:4D and risk taking, altruism, positive reciprocity, negative reciprocity and trust. However, ...

Seroepidemiological Study on the Spread of SARS-CoV-2 in Germany: Study Protocol of the ‘CORONA-MONITORING bundesweit’ Study (RKI-SOEP Study)

Das Coronavirus SARS-CoV-2 hat sich in kurzer Zeit bundesweit ausgebreitet. In den Meldedaten der Gesundheitsämter zu laborbestätigten Infektionsfällen ist von einer Untererfassung des Infektionsgeschehens auszugehen, da Infektionen häufig unentdeckt bleiben, zum Beispiel weil sie symptomarm verlaufen. In seroepidemiologischen Studien kann der Bevölkerungsanteil mit durchgemachter SARS-CoV-2-Infektion ...

Location, Location, Location: The Role of Objective Neighborhood Characteristics for Perceptions of Control

Introduction: Control beliefs can protect against age-related declines in functioning. It is unclear whether neighborhood characteristics shape how much control people perceive over their life. This article studies associations of neighborhood characteristics with control beliefs of residents of a diverse metropolitan area (Berlin, Germany). Methods: We combine self-report data about perceptions of ...

Cracking under Pressure? Gender Role Attitudes toward Maternal Employment in Times of a Pandemic

This paper studies the effects of Covid-19 related daycare and school closures on gender role attitudes toward maternal employment in Germany. We compare women and men with dependent children to those without children one year after the outbreak of the pandemic. Using data on gender role attitudes from 2008 through 2021, we find that fathers’ egalitarian attitudes toward maternal employment dropped ...

Corona-Monitoring bundesweit (RKI-SOEP-Studie): Überblick zu ersten Ergebnissen

Berücksichtigt man alle in der Studie erhobenen Informationen (IgG-Antikörper-Tests, PCR-Tests und Fragebögen), kann davon ausgegangen werden, dass sich nur etwa zwei von 100 Erwachsenen bis November 2020 mit SARS-CoV-2 infiziert hatten. Die Zahl der Infektionen ist etwa doppelt so hoch wie aus den Meldezahlen für den genannten Zeitraum bekannt (Untererfassung). Die Ergebnisse zeigen, dass Menschen ...
