Lifespan psychological research has long been interested in the contextual embeddedness of individual development. To examine if and how regional factors relate to between-person disparities in the progression of late-life well-being, we applied three-level growth curve models to 24-year...

Lack of reproducibility is seriously undermining the credibility of science as a whole. By extrapolating the findings of isolated checks, one may expect a substantial fraction of published articles in scientific journals to contain findings that simply do not hold. But we do not know which...

In Zeiten wachsender Publikationszahlen und zunehmend datenintensiver Forschung stoßen die klassischen Qualitätssicherungsmaßnahmen, wie die Peer-Review, an ihre Grenzen. Vor diesem Hintergrund werden Replikationsstudien verstärkt als gute wissenschaftliche Praxis und Lösungsansatz...

Political representatives frequently make decisions with far-reaching implications for citizens and societies. Most of these decisions are choices in situations in which the probabilities of gains and losses are hard to estimate. Although decision-making is crucial to politics, existing research...

People differ in their willingness to take risks. Recent work found that revealed preference tasks (e.g., laboratory lotteries)—a dominant class of measures—are outperformed by survey-based stated preferences, which are more stable and predict real-world risk taking across different domains....

This paper presents new evidence on the distribution of risk attitudes in the population, using a novel set of survey questions and a representative sample of roughly 22,000 individuals living in Germany. Using a question that asks about willingness to take risks on an 11-point scale, we find...

A particular shortcoming of panel surveys is potential bias arising from selective attrition. Based on data from the German Socio-Economic Panel Study (SOEP) we analyze potential artifacts (level, structure, inequality of income) by comparing results from two independently drawn panel...

To the best of our knowledge, most of the few methodological studies which analyze the impact of faked interviews on survey results are based on "artificial fakes" generated by project students in a "laboratory environment". In contrast, panel data provide a unique opportunity to identify data...
