Die Corona-Pandemie bietet einen einzigartigen Rahmen, um zu verstehen, wie Eltern zwischen Arbeitsangebot und Kinderbetreuung abwägen, wenn Schulen schließen. Obwohl die Schulbeschränkungen in den Jahren 2020/2021 in Deutschland die meisten Arbeitnehmer unberührt ließen, verteilten Haushalte mit Kindern im Grundschulalter die Arbeitskraft neu: Die Vollzeitbeschäftigung der Mütter, die nur Kinder im ...

DIW Discussion Papers 2173 / 2026
In this study, we examine the relationship between personality traits, captured by risk tolerance and the Big Five traits, and firm size, as measured by the number of employees. We show that the personality of entrepreneurs matters for the size of their firm they operate. We use a novel add-on to the German Socio-Economic Panel that includes a sub-sample of owner-managers running larger firms. High ...

Personality research in entrepreneurship often focuses on venture entry and survival, leaving personality traits associated with firm size underexamined. Using novel data from the German Socio-Economic Panel that include a sample of owner-managers running larger firms, we investigate the relationship between personality—measured by the Big Five traits and risk tolerance—and firm size captured by the ...

Background : Evidence-based interventions to reduce adolescents’ exposure to tobacco and air pollution are rarely implemented in low- and middle-income countries, often because they lack contextual fit. The ‘FRESHAIR4Life’ project aimed to optimise implementation of contextually adapted, evidence-based interventions in Greece, Kyrgyzstan, Pakistan, Romania, and Uganda. Selecting appropriate interventions ...

This paper explores the effect of COVID-19 infection rates on individuals’ risk preferences using the Socio-Economic Panel (SOEP), a large population-wide ran¬dom sample. Exploiting county-level variation in a difference-in-differences design, we find that risk preferences remain unchanged: the effect is precisely estimated at 2.1% of a standard deviation (95% CI: [−0.4%, +4.6%]), ruling out economically ...

We investigate the role of industrial relations for working from home during and after the COVID-19 pandemic in Germany. Using data from the German Socio-Economic Panel (SOEP) for the years 2020 to 2023 and a special COVID sample (SOEP-CoV) for 2020 and 2021, we examine how collective bargaining and plant-level co-determination are associated with the incidence and frequency of working from home. Controlling ...
