The effect of social comparison on debt taking: Experimental evidence

A number of studies show a link between social comparison and high levels of household debt. However, the exact underlying mechanisms are not yet well understood. In this paper, we disentangle two mechanisms in a lab experiment to study the effects of social image concerns and peer information on debt-financed consumption choices. We find that having to announce their consumption decisions publicly ...

Buffering effects of volunteering on the link between negative life events and adults' life satisfaction: Disentangling within- and between-person effects

This study explores how volunteering buffers the association between negative life events and life satisfaction using data from two longitudinal surveys: HILDA (30,693 participants, one-year intervals) and SOEP (60,701 participants, two-year intervals). We applied multiple-group random intercept cross-lagged panel models to examine how volunteering moderates the effects between dependent negative life ...

Mode choice inertia and shock: Three months of almost fare-free public transport in Germany

This study analyses travellers’ behavioural responses to two temporal measures implemented by the German government: the reduction in public transport prices, making it almost fare-free, and a decrease in fuel taxes to the minimum level permitted by European law. Based on a panel dataset of GPS-tracked trips collected before and during the price intervention from a representative sample of 276 individuals, ...

Socialism, identity and the well-being of unemployed women

Unemployment influences people’s life satisfaction beyond negative income shocks. A large body of literature investigates these non-pecuniary costs of unemployment and stresses the importance of social norms, especially for men. We add to this literature by showing that norm non-compliance may equally inflate the non-pecuniary loss of well-being for unemployed women. Using German panel data, we use ...

Redefining the personality profiles of early-stage solopreneurs: A cross-sector study

This study explores the diversity in the personality profiles of solopreneurs in high- and non-high-tech sectors during the initial business phase, driven by the need to determine whether sector specific personality traits are crucial for entrepreneurial success. Utilizing the Big Five personality traits (BFPT), we analyze data on 4,470 solopreneurs from the IAB/ZEW Start-up Panel (2018 and 2019 waves). ...

A dataset of study program availability in German higher education between 1971 and 1996

Educational systems are dynamic. They shape human capital, technological and societal progress, and also economic growth. Higher education, in particular, fosters innovation, with varying fields of study contributing differently to this process. Yet, despite its importance, no dataset has previously documented the evolution of academic fields across higher education institutions in a specific country. ...

Chat about SOEP Research Data: A RAG System for Interactive SOEP Data Exploration

The German Socio-Economic Panel (SOEP) is one of the world’s longest-running household panel studies, containing rich longitudinal data spanning over four decades. However, the complexity and scale of SOEP data present significant challenges for researchers in data discovery and exploration. This paper presents a prototype Retrieval Augmented Generation (RAG) system designed to provide conversational ...

Accelerating social science knowledge production with the coordinated open-source model

With the growing complexity of knowledge production, social science must accelerate and open up to maintain explanatory power and responsiveness. This goal requires redesigning the front end of the research to build an open and expandable knowledge infrastructure that stimulates broad collaborations, enables breaking down inertia and path dependencies of conventional approaches, and boosts discovery ...
