Im Kern eines Instrumentenmixes für die deutsche Energie- und Klimapolitik sollte nach Ansicht von Andreas Löschel, Universität Münster, eine allgemeine CO2-Bepreisung stehen, die einen ökonomisch sinnvollen und langfristigen Rahmen für die umfangreiche Transformation setzt. Bei...

Die Preise für Energierohstoffe wie Gas und Rohöl sind in den vergangenen Monaten auf Rekordniveau gestiegen. Sollte Klimapolitik auf diese Energiepreisanstiege reagieren und kurzfristig CO2 -Preise anpassen, um Haushalte zu entlasten? In unserer Analyse adressieren wir diese Frage in einem...

A rapid coal phase-out is needed to meet the goals of the Paris Agreement, but is hindered by serious challenges ranging from vested interests to the risks of social disruption. To understand how to organize a global coal phase-out, it is crucial to go beyond cost-effective climate mitigation...

The year 2020 marks the centennial of the publication of Arthur Cecil Pigou's magnum opus The Economics of Welfare. Pigou's pricing principles have had an enduring influence on the academic debate, with a widespread consensus having emerged among economists that Pigouvian taxes or subsidies are...

Die Abscheidung und Lagerung von CO2 wird zunehmend als Option im Rahmen einer Klimaschutzstrategie diskutiert. Wie sicher und wie wirksam ist diese Methode? Ottmar Edenhofer, Brigitte Knopf und Matthias Kalkuhl, Potsdam-Institut für Klimafolgenforschung, Berlin, machen deutlich, dass die...

This paper takes the ‘policy failure’ in establishing a global carbon price for efficient emissions reduction as a starting point and analyzes to what extent technology policies can be a reasonable second-best approach. From a supply-side perspective, carbon capture and storage (CCS)...

We investigate conditions that amplify market failures in energy innovations, and suggest optimal policy instruments to address them. Using an intertemporal general equilibrium model we show that ‘small’ market imperfections may trigger a several decades lasting dominance of an incumbent...

This article contributes to the ongoing discussion on the drivers of food price volatility. Based on theoretical considerations, economical, agricultural, and political determinants of domestic price volatility are identified and discussed. A dynamic panel is estimated to account for country...

Understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and, hence, assessing the global food supply situation. This study makes...
