Abstract

We model the interactions between management regimes (municipal vs. delegated) and operating costs of water supply services in order to compare their performance and pricing. We estimate the models from panel data in France. We show that the choice between management regimes at the local community level depends on costs and service characteristics, that there is a significant difference in average productive efficiency in favor of delegated services, and that municipal services appear more efficient in network returns. Under delegation, the margins realized by operators depend on service and contract characteristics. Nous modélisons les interactions entre mode de gestion (régie ou délégation) et coûts d'exploitation des services d'eau potable afin de comparer leurs performances et la tarification. Nous estimons ces modèles sur des données de panel en France. Nous montrons que le choix de la collectivité locale dépend des coûts et des caractéristiques des services. Il existe une différence significative d'efficacité productive moyenne en faveur de la gestion déléguée, mais les services en régie semblent plus performants sur les rendements de réseau. Les marges réalisées par l'exploitant sont expliquées par les caractéristiques des services, et celles du contrat dans le cas de délégation.
