This paper estimates economies of scale and scope for 55 major Australian urban utilities over the period 2005/06 to 2008/09. The models used to specify operating and capital costs as a function of chemical and microbiological compliance, water losses, water quality and service, water main...

In this paper, we investigate productivity growth in 55 major Australian urban water utilities using nonparametric frontier techniques over the period 2005/06 to 2008/09. The five outputs included in the analysis are chemical and microbiological compliance, and the inverses of real loses per...

Environmental factors add complexity to the comparison between specific activities or entire entities. Decision making units with an inferior performance are tempted to invoke that their organization is different from the others in the data set. By reinterpreting and extending the metafrontier...

The paper investigates the organization of the Italian water sector in the light of the reforms of public utilities. The aim is to examine the degree of implementation of the water sector reform (the so-called Galli Law of 1994) and assess the performance of operators through a study of their...

This study provides a comprehensive efficiency analysis of water service providers in six countries in the Central American region. Pressures for sector reform have stimulated interest in identifying and understanding the factors that can contribute to network expansion, improved service...

This paper uses a Data Envelopment Analysis (DEA) and a Stochastic Frontier Analysis (SFA) to assess the relative technical efficiency of 177 decision making units in the French water supply sector in 2009. Water utilities can be directly managed by the local authorities or contracted out and...

Potable water supply in Germany is highly fragmented. A consolidation of the industry could, therefore, lead to lower cost of water supply and price savings for the customers. In this paper we estimate a total cost function for potable water supply based on a unique sample of German water...

The Dutch drinking water sector experienced two drastic changes over the last 10 years. Firstly, in 1997, the sector association started with a voluntary benchmarking aimed to increase the efficiency and effectiveness of the sector. Secondly, merger activity arose. This paper develops a tailored...
