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 ...

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 ...

Investors personality correlates with sustainability preferences in investment – A choice experiment with Spanish investors

According to behavioral economics, investors’ decisions are influenced by factors beyond rational reasoning, such as an investor's personality. This paper explores the relationships between personality, using the Big Five personality traits framework, and the willingness to invest in assets that contribute to achieving sustainable development goals (SDGs), more specifically, sustainable finances. ...

The dynamics of household location preferences in Germany

Inspired by the literature on social polarisation and residential segregation we draw on a probabilistic approach to pursue the evolution of household location preferences. Using microdata from the German Socio-Economic Panel (SOEP) for the period 1984–2020 we demonstrate that structural economic change was accompanied by an increasing preference for residence in compact housing close to urban centres. ...

Fathers’ sleep in the first 24 months postpartum: A systematic review and meta-analysis of global data

Maternal sleep is significantly disrupted in the postpartum period, but changes in paternal sleep are less established. Here, we systematically review and meta-analyze available data on paternal sleep in the first 24months post birth, including self-report and objectively measured sleep outcomes. Scopus, PsycINFO, and PubMed were searched for original research articles published until end August 2024. ...

Actor-Driven Risk Factors of Publication Bias: Opening the File Drawer of Two Probabilistic Panel Surveys

Science has long struggled with unsuccessful replications and reproductions, a challenge that raises questions about the robustness and credibility of research findings. One potential contributing factor is selective reporting or nonpublication of certain results based on their direction or strength, leading to publication bias. To better understand its extent and risk factors, we examined 178 successful ...
