In this paper we test the hypothesis that the economic transition toward a market economy increases the efficiency of firms. We study 32 Polish electricity distribution companies between 1997-2002, by applying common benchmarking methods to the panel: the nonparametric data envelopment analysis (DEA), the free disposal hull (FDH), and, as a parametric approach, the stochastic frontier analysis (SFA). ...
The objective of this paper is to develop a model to determine the price formation of wholesale electricity markets. For that purpose, we model wholesale electricity prices depending on the prices of fuels (coal and natural gas) and of CO2 emission allowances using a Markov Switching Regression. We apply the model to wholesale electricity prices in the UK and in Germany. While British electricity prices ...
In spite of the sharp decline of crude oil prices since the fall of 2008, the current price level of approximately $65 per barrel is significantly higher than the long-term average. The market power of the Organization of Petroleum Exporting Countries (OPEC), which is partially responsible for this price level, remains strong. While market prices for commodities such as coal are typically reflecting ...

Bestimmung eines robusten Mix von Energieträgern für eine kohlenstoffneutrale EU Das europäische Energiesystem muss klimafreundlicher und dafür grundlegend umgebaut werden. Es besteht jedoch große Unsicherheit, wie das europäische Energiesystem im Jahr 2050 aussehen wird. In diesem Projekt haben wir einen Überblick über die derzeit angedachten Perspektiven zum Wandel der Sektoren Kohle, Erdgas...
