Abstract

Un résultat communément accepté dans la littérature sur la régulation des services publics (Coase [1946]) est que l'efficience du marché exige un recours à des tarifs binômes avec, d'une part, un prix marginal égal au coût marginal et, d'autre part, un prix fixe correspondant à la part de coûts fixes prise en charge par chaque abonné. En France, les usagers des services d'eau payent un prix marginal qui est en moyenne 8 % plus élevé que le coût marginal. Selon nos estimations de l'élasticité-prix, qui sont similaires à celles obtenues dans les précédentes études, les coûts d'efficience représentent une perte de près de 8 millions d'euros en 2008. Même si la distorsion demeure relativement faible, les consommateurs pourraient bénéficier de ces gains d'efficience.
