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, ...

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 ...

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. ...

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 ...

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 ...

What are the electoral consequences of nuclear energy for Green parties? Despite the centrality of nuclear opposition to Green party platforms, and the social movements that helped them emerge, little research has examined the electoral impact of this stance. Building on work on energy transitions and local political economy, we propose that the economic benefits of nuclear power can mitigate local ...

Although socioeconomic status (SES) is related to students’ well-being, many studies consider only a single SES indicator and one dimension of well-being, providing an incomplete picture. The present study examined SES-related differences among a large sample of elementary school students in Germany. We employed multiple SES indicators, considered both cognitive and psychological dimensions of well-being, ...

Cultivated land transfer serves as an efficient way to mitigate the escalating issue of cultivated land abandonment due to labor migration driven by the urban-rural gap, while also ensuring national food security. Nevertheless, the impact of how urban-rural resident’ life quality gap (RLQG) affect cultivated land transfer decision-making remains unclear. This study developed a theoretical framework ...

Performance-contingent pay raises productivity, yet in the German Socio-Economic Panel (SOEP) only about 16% of workers report receiving performance pay, with the incidence being roughly seven percentage points higher among university graduates than among non-graduates. This coexistence of low aggregate take-up and a strong skill gradient is puzzling. This paper accounts for these twin facts with a ...
