Social and nonlinear tariffs in safe water in France: cui bono?
The paper “Social and nonlinear tariffs in safe water in France: cui bono? An empirical study applied on a natural experiment in France” (Mayol, A., Porcher, S.) will be presented at the 5th Conference on the Regulation of Infrastructures (24 June 2016).
This empirical study discusses both efficiency and equity of the nonlinear tariffs in the safe water sector. The management of this specific good is caught in the middle of two objectives: saving this natural resource on the one hand, while ensuring its access to everyone on the other. For this reason, authorities wish to explore innovative discriminatory progressive tariffs clustered with social measures. Using an original panel database, we econometrically explore the impact of tariffs changes on consumption (linear versus non linear) on a natural experimentation in France. We show that this measure reduces global consumption. However, we also find that the cost is not equally shared by all consumers. Public policy implications of such tariffs in safe water may lead to discussions on their real efficiency, reviving the ancient adage: cui bono?
