We investigate conditions that aggravate 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 paper evaluates the consequences of renewable energy policies on welfare, resource rents and energy costs in a world where carbon pricing is imperfect and the regulator seeks to limit emissions to a (cumulative) target. We use a global general equilibrium model with an intertemporal fossil...

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) policies...

Die deutsche Klimapolitik benötigt eine grundlegende Neuausrichtung. Deutschland muss im Rahmen der EU-Lastenteilungsverordnung bis 2030 seine Emissionen im Verkehrs-, Gebäude- und Landwirtschaftssektor sowie in Teilen des Industrie- und Energiesektors um 38 Prozent gegenüber 2005 vermindern,...

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. The innovations of the...

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...

The study revealed the strong impact of policy measures on production, procurement, stocks and trade. We detected several market distortions and mounting fiscal costs. Wheat and rice supply strongly and significantly respond to the minimum support price (MSP). Wholesale prices at planting or...

Interest rates are central determinants of saving and investment decisions. Costly financial intermediation distort these price signals by creating a spread between the interest rates on deposits and loans with substantial effects on the supply of funds and the demand for credit. This study...
