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....

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...

We empirically demonstrate a practical approach of efficiency evaluation with limited data availability in some regulated industries. We apply PCA-DEA for radial efficiency measurement to U.S. natural gas transmission companies in 2007. PCA-DEA reduces dimensions of the optimization problem...

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...

Seit Anfang 2009 unterliegt die Energieversorgung in Deutschland der Anreizregulierung, durch die ein effizienter Betrieb von Strom- und Gasnetzen sichergestellt werden soll. Unklar ist allerdings, wie sich die veränderten regulatorischen Rahmenbedingungen auf das Investitionsverhalten der...

[Einleitung] 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 auch die richtigen...

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...

This paper examines firm-level productivity for German electricity retailers using a structural production function approach. The sector was subject to fundamental changes in market structure after retail liberalization in 1998. Competition was supposed to increase productivity and reduce retail...

In this paper, we propose a probabilistic voter model that rationalizes the ineff cient use of labor input in municipality-owned enterprises. Our focus is on the relationship between absolute as well as relative ineff ciency measures and the size of the municipality in which public rms operate....
