Publishing in Small Business Economics: An Entrepreneurship Journal

Publishing entrepreneurship research is not just important but challenging. Longstanding experts in the field can provide helpful advice. As borders between academic fields blur, research fields are increasingly global in their perspective, knowledge, and findings, thus enabling robust participation in research fields at a scale previously unimaginable. Drawing on the experience, insights, and perspectives ...

Gender Identity and Wives’ Labor Market Outcomes in West and East Germany between 1983 and 2016

We exploit the natural experiment of German reunification in 1990 to investigate if the institutional regimes of the formerly socialist (rather gender-equal) East Germany and the capitalist (rather gender-traditional) West Germany resulted in differing gender norms regarding who should be the family breadwinner. We use data for three periods between 1983 and 2016 from the German Socio-Economic Panel. ...

2D:4D and Self-Employment: A Preregistered Replication Study in a Large General Population Sample

The 2D: 4D digit ratio, the ratio of the length of the second finger to the length of the fourth finger, is often considered a proxy for testosterone exposure in utero. A recent study reported, among other things, an association between the left-hand 2D:4D and self-employment in a sample of 974 adults. In this preregistered study, we replicate the 2D:4D results on a sample of more than 2100 adults ...

Chances and Barriers for Germany’s Low Carbon Transition: Quantifying Uncertainties in Key Influential Factors

With the energy sector being one of the largest sources of global greenhouse-gas emissions, a swift change in the ways of energy generation and consumption is needed for a fulfilment of climate goals. But while the existence of global warming and the resulting need for action are widely agreed upon, there is a lot of discussion around the concrete measures and their timeline. A major cause of this ...

Centralized and Decentral Approaches to Succeed the 100% Energiewende in Germany in the European Context – A Model-based Analysis of Generation, Network, and Storage Investments

In this paper, we explore centralized and more decentral approaches to succeed the energiewende in Germany, in the European context. We use the AnyMOD framework to model a future renewable-based European energy system, based on a techno-economic optimization, i.e. cost minimization with given demand, including both investment and the subsequent dispatch of capacity. The model includes 29 regions for ...

Linking Brain Age Gap to Mental and Physical Health in the Berlin Aging Study II

From a biological perspective, humans differ in the speed they age, and this may manifest in both mental and physical health disparities. The discrepancy between an individual’s biological and chronological age of the brain (“brain age gap”) can be assessed by applying machine learning techniques to Magnetic Resonance Imaging (MRI) data. Here, we examined the links between brain age gap and a broad ...

How Migration Status Shapes Susceptibility of Individuals’ Loneliness to Social Isolation

Objectives: Our research provides competing hypotheses and empirical evidence how associations between objectively social isolation and subjective loneliness differ between host populations, migrants, and refugees.Methods: The analysis uses data of 25,171 participants from a random sample of the German population (SOEP v.35). We estimate regression models for the host population, migrants, and refugees ...

Gender, Loneliness and Happiness during COVID-19

We analyse a measure of loneliness from a representative sample of German individuals interviewed in both 2017 and at the beginning of the COVID-19 pandemic in 2020. Both men and women felt lonelier during the COVID-19 pandemic than they did in 2017. The pandemic more than doubled the gender loneliness gap: women were lonelier than men in 2017, and the 2017-2020 rise in loneliness was far larger for ...

Nationally Representative Results on SARS-CoV-2 Seroprevalence and Testing in Germany at the End of 2020

Pre-vaccine SARS-CoV-2 seroprevalence data from Germany are scarce outside hotspots, and socioeconomic disparities remained largely unexplored. The nationwide representative RKI-SOEP study (15,122 participants, 18–99 years, 54% women) investigated seroprevalence and testing in a supplementary wave of the Socio-Economic-Panel conducted predominantly in October–November 2020. Self-collected oral-nasal ...
