Gutverdiener haben oft mehr von der gesetzlichen Rente. Eine Reform ist dringend nötig. Einige der aktuellen Vorschläge gehen jedoch in die völlig falsche Richtung. Die Vorsitzende der Wirtschaftsweisen, Monika Schnitzer, hat tiefgreifende Reformen der gesetzlichen Rente vorgeschlagen und damit Aufsehen erregt. Schnitzer bezog sich auf einen älteren Bericht des Sachverständigenrats der Bundesregierung. ...
Energy system models are used for policy decisions and technology designs. If not carefully used, models give implausible outputs and mislead decision-making. One implausible effect is “unintended storage cycling”, which is observable as simultaneous storage charging and discharging. Methods to remove such misleading effects exist, but are computationally inefficient and sometimes ineffective. Through ...
The influential Indian Parliamentarian Mr. Jayant Sinha envisages a global climate alliance building on the concept of the European Union and its Green Deal – a community attractive to its members because it addresses the diverse needs and ensures that joint action benefits all. To ensure the inclusive nature and broaden the political ownership of such an initiative, Mr. Sinha launched a report on...

Recently, decentralized local energy markets have evolved, often as isolated networks based on solar generation. We analyze strategic pricing, investment, and welfare in local energy markets. We show that local energy markets yield competitive equilibrium prices and ...
Self-efficacy reflects the self-belief that one can persistently perform difficult and novel tasks while coping with adversity. As such beliefs reflect how individuals behave, think, and act, they are key for successful entrepreneurial activities. While existing literature mainly analyzes the influence of the task-related construct of entrepreneurial self-efficacy, we take a different perspective and ...
The long-run U-shaped patterns of economic inequality are standardly explained by basic economic trends (Piketty’s r > g), taxation policies or ‘great levellers’ such as catastrophes. This article argues that housing policy, and particularly rent control, is a neglected explanatory factor in understanding macro inequality. We hypothesize that rent control could decrease overall housing wealth, lower ...
Frauen verdienen immer noch deutlich weniger als Männer. Geht es so weiter, werden sich die Stundenlöhne erst in 50 Jahre angleichen. Die Politik muss endlich handeln. Deutschland hat einen der größten Gender-Pay-Gaps in Europa. In kaum einem anderen westlichen Land ist der Unterschied beim Stundenlohn zwischen Männern und Frauen so groß. Das ist ein Armutszeugnis für Deutschland, denn er ist das Resultat ...
