Linking Social Media News Use, AI Interest, and Political Ideology With AI Subjective Knowledge: A Moderated Mediation Model Across Two Countries

Social media has emerged as a pivotal platform for accessing news content today. While there appears to be a connection between news consumption on social media platforms and perceived knowledge of public affairs, little is known about the potential effect on specific issues like artificial intelligence (AI). To extend findings on people’s perceived knowledge of AI, how it relates to social media news ...

Wieso ist das Vermögen in Deutschland so ungleich verteilt?

Genes, Cognitive Skills, and Preferences

We examine the relationship between cognitive genetic endowments, measured via a validated polygenic index, and economic preferences. Using representative panel data linking genetic information to stated and revealed preferences, we find that higher cognitive PGI scores are associated with greater risk aversion, increased prosociality, and higher likelihood of holding financial assets, but show no ...

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). ...
