Family background and life cycle earnings volatility: evidence from brother correlations in Denmark, Germany, and the United States

While stratification scholars have extensively examined intergenerational associations in lifetime income, they have mostly disregarded how family background affects exposure to income volatility over the life course. As exposure to volatility represents a non-desirable outcome associated with negative shocks to individuals’ welfare, studying the link between family background and volatility is key ...

The Artificial Intelligence Experience and Attitude Survey (AIEAS): A Brief Measure forSocio-Economic Panel Studies

Large-scale socio-economic panel studies aim to document societal trends and public opinions using representative population samples. Despite the profound impact of artificial intelligence (AI) on public and private life across diverse contexts, these studies have rarely addressed the use and evaluation of AI for individual respondents. Therefore, a standardized assessment instrument is introduced ...

The German Artificial Intelligence Experience and Attitude Survey (AIEAS): A Brief Measure for Socio-Economic Panel Studies

Despite the profound impact of artificial intelligence (AI) in diverse contexts, large-scale socio-economic panel studies have rarely addressed the use and evaluation of AI for individual respondents. Therefore, the Artificial Intelligence Experience and Attitude Survey (AIEAS) is introduced to measure awareness, experience, attitude valence, and usage intention regarding AI in the work, healthcare, ...

Minimum wage non-compliance: the role of co-determination

We analyse how co-determination is related to non-compliance with the German minimum wage, which was introduced in 2015. The Works Constitution Act (WCA), the law regulating co-determination at the plant level, provides works councils with indirect means to ensure compliance with the statutory minimum wage. Based on this legal situation, our theoretical model predicts that non-compliance is less likely ...

Global motivation to learn and adult learning: A nomological network analysis and a four-year longitudinal study

This study investigated motivation to learn (MtL), conceptualized at a global level of abstraction, and participation in adult learning and training (PAE). In Study 1 (N = 747, 65.1 % female; age: M[SD] = 43.21[12.09] years), the nomological network of global MtL revealed strong correlations with mastery goal orientation, intrinsic task value, need for cognition, and self-concept of ability. Cross-sectional ...

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 ...

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 ...

Random Forests for Labor Market Analysis: Balancing Precision and Interpretability

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 ...
