This paper analyzes the conduct of publicly owned monopolistic utilities regulated by a voluntary sunshine regulatory model (i.e. publication of the performances of utilities). In particular, we examine the behaviour of Dutch drinking water utilities before and after the introduction of the...

Cross-country comparisons avoid the unsteady equilibrium in which regulators have to balance between economies of scale and a sufficient number of remaining comparable utilities. By the use of Data Envelopment Analysis (DEA), we compare the efficiency of the drinking water sector in the...

In this study we apply an index number approach to allow for cross sectional comparisons of relative profitability, productivity and price performance of the regulated Water and Sewerage companies (WaSCs) in England and Wales during the years 1991-2008. In order to better analyse the impact of...

This paper analyses the foundations of efficient-firm regulation (implemented in Chile for almost two decades), and the formulas that are used to set the prices of water/sanitation companies, electric power distributors and the dominant phone companies. We show that efficient-firm regulation...
