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...

Germany's water supply industry is characterized by a multitude of utilities and widely diverging prices, possibly resulting from structural differences beyond the control of firms' management, but also from inefficiencies. In this article we use Data Envelopment Analysis and Stochastic Frontier...

Yardstick regulation requires the utilization of benchmarking, a valuable tool for improving the public service delivery, especially in developing countries where inefficiencies translate into negative health impacts and social unrest. However, research must account for both cost and quality of...

We assess the efficiency of urban water supply in 27 Indian cities using data envelopment analysis (DEA). We also group cities by the management structure of their water utilities. Utilities with greater degree of functional autonomy perform better, supporting the hypothesis that more autonomy...

Substantial structural reform has occurred in the water and wastewater sectors of Australia’s major urban centers over the past two decades. This reform has involved the corporatization of government assets and some vertical and horizontal separation. This paper analyses the performance of...

The purpose of the current study was to assess energy, economic, and environmental efficiency based on the environmental reforms of the top 10 carbon dioxide (CO2) emitter countries by using the Data Envelopment Analysis (DEA) model from 2013 to 2017 to assess energy pricing and market reforms...

There are some specific features of the non-radial DEA (data envelopment analysis) models which cause some problems under the returns to scale measurement. In the scientific literature on DEA, some methods were suggested to deal with the returns to scale measurement in the non-radial DEA models....

German savings banks play a key role in financing German SMEs. Accordingly, the analysis of their efficiency is of economic importance. We apply data envelopment analysis to explore the influence of the financial crisis (2007 to 2008) as well as the Eurozone crisis (since the end of 2009) on the...
