This paper provides an empirical demonstration for a practical approach of efficiency evaluation against the background of limited data availability in some regulated industries. Here, traditional DEA may result in a lack of discriminatory power when high numbers of variables but only limited...

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs....

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...

Since early 2009, power supply 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 distribution system...

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 provide a comprehensive multivariate cointegration analysis of three parts of the steam coal value chain — export, transport and import prices. The analysis is based on a rich dataset of international coal prices; in particular, we combine data on steam coal prices with...

The analysis is based on a rich dataset of international coal prices; in particular, we combine data on steam coal prices with freight...

This paper examines the impact of endogenous deficit-balancing subsidies on the cost efficiency of local public bus companies by using alternative frontier cost models for panel data. Thereby, the multidimensional performance estimation incorporates the subsidy variable directly. The empirical...
