Resumen de Efficiency in water supply NETWORK.ERDF impact evaluation. Spain (2007-2010)

Ignacio Moral Arce, María Gorriti

• This paper studies the effect that water projects, financed by EU funds, have had on the efficiency of water distribution in the period 2007-2010. Using data from Spanish municipalities, we performed a descriptive analysis of the evolution from this period. Then, we study the impact that structural EU funds have on the efficiency in water distribution using the diff-in-diff approach. W ith different specifications of panel data, we calculate the impact that these projects have on the result variables under study. The estimation results show that ERDF co financed works have a significant effect in reducing the amount of water supplied per capita, as well as in terms of reducing water leakages, but the impact on the second variable is not as clear as the effect in per capita water distribution.
