This study examines the association between dog ownership over a period of 5 years (always, sometimes and no ownership) with physical activity on weekdays and weekends over a period of 6 years using the nationally representative German Socio-Economic Panel. Participants were asked if they had any pets and how many hours they spend on sports, fitness, and exercise. We hypothesized that the length of ...

This paper analyzes the distribution and composition of pre-tax national income in Germany since 1992, combining personal income tax returns, household survey data, and national accounts. Inequality rose from the 1990s to the late 2000s due to falling labor incomes among the bottom 50% and rising incomes in the top 10%. This trend reversed after 2007 as labor incomes across the bottom 90% increased. ...
Cognitive abilities are associated with key preferences and socio-economic outcomes. One of the most frequently studied cognitive abilities is cognitive reflection, the ability to avoid intuitive but potentially wrong decisions by switching to a more analytical mindset. Using rich panel data in this pre-registered study, we show that stronger cognitive reflection is significantly associated with more ...
Variable renewable energy droughts, also referred to as "Dunkelflaute", emerge as a challenge for realizing climate-neutral energy systems based on variable wind and solar power. Using data on 38 historic weather years and an advanced identification method, we characterize European drought events for on- and offshore wind power, solar photovoltaics, and policy-relevant renewable technology portfolios. ...
Coping with prolonged periods of low availability of wind and solar power, also referred to as "Dunkelflaute", emerges as a key challenge for realizing a decarbonized European energy system fully based on renewable energy sources. Here, we investigate the role of long-duration electricity storage and geographical balancing in dealing with such variable renewable energy droughts. To this end, we combine ...
