Impacto de la inversión pública en la tasa de cobertura de los servicios de agua potable, alcantarillado y energía eléctrica, un análisis de convergencia a nivel provincial en el período 2007-2015

Abstract

The objective of this study is to measure the impact of public investment on the coverage rates of potable water, sewerage and electric power services in Ecuador, to evaluate the efficiency of the Country’s Provinces in the management of investment about coverage of the services mentioned and analyze the existence of convergence at provincial level in coverage rates. With annual information from 21 Provinces for the period 2008-2015, an econometric panel data model was used to find variables that have impact in coverage rates. By applying a model Data Envelopment Analysis (DEA) was evaluate the performance of the various provinces around service coverage and application of the model (Barro & Sala-i-Martin, 1991) that allowed finding the speed at which the coverage rates of services converge at the provincial level. The results show a positive and significant relationship between public investment and coverage rates for potable water, sewerage and electricity. Regarding the efficiency of the investment on the coverage of services, it was found that the majority of Provinces achieved good results related to coverage with the available transfers. Finally, the hypothesis of convergence in coverage rates was verified.
