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 ...

DIW Weekly Report 34/35 / 2026
The COVID-19 pandemic provides a unique context for understanding how parents balance labor supply and childcare when schools close. Although school restrictions in Germany left most workers unaffected, households with children of elementary school age redistributed their labor: Full-time employment among mothers who had only children of elementary school age fell by four to five percentage points ...

Objective: This study examines the link between parental migration status and ECD of children aged 2–4 and investigates ...

An influential survey by Joshua Knobe (2003) indicates that the cognitive process ascribing intentionality to an agent is mediated by the perceived moral worth of the action. To assess the external validity of the finding and to obtain more precise estimates of effect sizes, the present study replicates this canonical experiment with a large scale random sample of the German population (N = 2,295). ...

Objectives Cumulative advantage is a central concept in life course research. Prior research has primarily focused on one outcome domain, overlooking the possibility that cumulative advantage could extend into other domains–what we refer to as diffusion of cumulative advantage. We build on and extend cumulative inequality theory to conceptualize diffusion and apply it to wealth and health, two domains ...

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 ...
