Abstract

As first noticed by Coase [1946], a standard result in utility regulation is that efficiency requires two-part tariffs with marginal prices set to marginal costs and fixed fees equal to each customer?s share of fixed costs. Residential water customers in France face marginal prices for water that average about 8 % more than marginal costs. Under price elasticity estimates that are consistent with previous results in the literature, efficiency costs represent around 8 million euros of welfare losses for 2008. Even though the distortion is fairly small, consumers could benefit from these efficiency gains. Classification JEL: D21, D82, L33, L95.
