Issues on service quality are crucial for water utility management and regulation. Omitting these aspects can lead to possible bias in estimating the efficiency of services. We integrate in a Translog cost function variables proxying this multi-dimensionality. Empirical results show that taking...

Issues related to service quality are crucial for water utility management and regulation. Omitting these aspects, especially when they are treated as exogenous, can lead to large biases in estimating cost functions as well as to misleading information concerning technology. In this article, we...

This paper provides a framework that aims at distinguishing the technological economies of vertical integration from the vertical economies resulting from market imperfections. To illustrate our analyze, we use consistent panel data econometric methods to estimate cost functions on a sample of...

In this paper, we provide an analysis of the water sector in France. Together with a description of the specificities of water delivery and the collection and treatment of waste waters, we highlight three crucial points to understand "the French water school"": the organization of the sector,...

Il existe un débat récurrent en France sur le choix d’organisation, de mode de gestion et de régulation des services d’eau. Ce sont des monopoles locaux qui peuvent être gérés directement par la commune ou délégués à un opérateur privé. L’analyse économétrique des coûts des...

Network losses and returns are importantissues for water resource management, that are addressed in thispaper by modeling the structure of production for municipal waterutilities with two outputs: water sold to final customers andwater network losses. We propose a measure of economies of scopeto...

This study proposes an econometric analysis of household fuelwood demand in France. The choice concerning the energy used for heating is modeled, stressing the combination between one type of energy used as a main source and another one used as a back-up. This endogenous decision has an impact...
