Consistencia de medidas de eficiencia basadas en funciones de distancia paramétricas y no paramétricas: una aplicación al sector de distribuidoras de electricidad en la Argentina

This paper estimates the technical efficiency of a set of Argentinean firms in the electric distribution sector for the period 1994-2001. The efficiency measurement involves the application of two methods: one non-parametric and the other parametric. The first one is DEA and the second one is the distance functions. Additionally, we focus on the construction of the efficient frontier for both methods. We present the consistency conditions for both methodologies in order to test weather both of them tend to give the same answer to the question of the efficiency measurement of the firms in the sample.
