Seit Anfang 2009 unterliegt die leitungsgebundene Energieversorgung in Deutschland der Anreizregulierung, durch die ein effizienter Betrieb von Strom und Gasnetzen sichergestellt werden soll. Unklar ist allerdings, inwieweit die Anreizregulierung sich auf Investitionen in Ersatz und Ausbau der...

In this paper, we analyze the technical efficiency of CO2 reduction potentials of German power and heat plants, using a non-parametric sequential Data Envelopment Analysis. We apply a metafrontier framework to evaluate plant-level efficiencies in the transformation of inputs into desirable...

This study applies non-parametric and parametric tests to assess the efficiency of electricity distribution companies in Germany. Traditional issues in electricity sector benchmarking are addressed, such as the role of scale effects and optimal utility size, as well as new evidence specific to...

We analyze the technical efficiency of German and Swiss urban public transport companies by means of SFA. In transport networks we might face different network structures or complexities, not observed, but influencing the production process. The unobserved factors are typically modeled as...

This paper assesses the relative efficiency of knowledge production in the OECD using a nonparametric DEA approach. In general, resources allocated to R&D are limited and therefore must be used efficiently, given the institutional and legal constraints. The efficiency scores presented are based...

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 and 2002, by applying common benchmarking methods to the panel: the non-parametric data envelopment...

Since early 2009, electricity and gas distribution in Germany has been subject to incentive regulation designed to ensure greater efficiency in electricity and gas grid operation. However, it remains to be seen how changes to the regulatory framework will affect the investment behavior of...
