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, ...
In proxy vector autoregressive models, the structural shocks of interest are identified by an instrument. Although heteroscedasticity is occasionally allowed for in inference, it is typically taken for granted that the impact effects of the structural shocks are time-invariant despite the change in their variances. We develop a test for this implicit assumption and present evidence that the assumption ...
Im Rahmen einer Längsschnittanalyse des sozio-oekonomischen Panels gehen wir der Frage nach, wie sich Diskriminierungswahrnehmungen von Einwanderern und ihren Nachkommen im Laufe des Integrationsprozesses verändern. Insgesamt betrachtet fühlen sich Migrantinnen und Migranten, deren Integration weiter fortgeschritten ist, seltener aufgrund ihrer Herkunft benachteiligt. Allerdings zeigen gruppenspezifische ...
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 ...
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 ...
After an economically tough start into the new millennium, Germany experienced an unprecedented employment boom after 2005 only stopped by the COVID-19 pandemic. Persistently high levels of inequality despite a booming labour market and drastically falling unemployment rates constituted a puzzle, suggesting either that the German job miracle mainly benefitted individuals in the mid- or high-income range ...
Global recovery is progressing more slowly than was indicated in 2020 due to high coronavirus rates and related economic restrictions in Europe and Japan. Recently, a disparate picture has been forming: In the advanced economies, declining infection rates and continued progress in vaccination campaigns will presumably lead to a revival that will be especially noticeable in the retail and service sectors ...
