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 ...
Das Jahr 2024 war von wirtschaftlichen Herausforderungen und politischer Unsicherheit geprägt. Konjunkturelle und strukturelle Probleme bremsten die Wirtschaft aus. Populistische Kräfte konnten bei Landtagswahlen, der Europa- und der US-Wahl deutlich zulegen. Zuletzt platzte auf Bundesebene noch die Ampelkoalition. Die Jahresübersicht umfasst Medienbeiträgen von Marcel Fratzscher zu den Bereichen Gesellschaftspolitik, ...
Das SCP ist eine Längsschnittstudie, die vielfältige Aspekte des gesellschaftlichen Zusammenhalts in Deutschland erfasst. Es basiert auf einer repräsentativen Bevölkerungsstichprobe aus deutschen Einwohnermelderegistern und wurde 2021 zum ersten Mal durchgeführt. Die jährliche Befragung richtet sich nicht nur an die ausgewählten Personen, sondern auch an alle anderen erwachsenen Haushaltsmitglieder. ...
The SCP is a longitudinal study that captures multiple aspects of social cohesion in Germany. It is based on a representative population sample drawn from the German population registers and was carried out for the first time in 2021. The annual survey is directed not only at the selected individuals but also at all other adult household members. The SCP is funded by the Federal Ministry of Education ...
We quantify the unintended effects of a low-wage payroll tax reduction using an equilibrium search model featuring bargaining, worker and firm productivity heterogeneity, labor taxes, and a minimum wage. The decentralized economy is inefficient due to search externalities and labor market policies. We estimate the model using French data and find that a significant reduction in low-wage payroll taxes ...
