Benchmarking in the sanitation sector in Brazil: An application of stochastic frontier panel data
In this study the technical efficiency of operation and maintenance costs of the providers of water and sanitation in Brazil is estimated using data from the National System of Information on Sanitation (SNIS) during 2004 and 2008.

| description | In this study the technical efficiency of operation and maintenance costs of the providers of water and sanitation in Brazil is estimated using data from the National System of Information on Sanitation (SNIS) during 2004 and 2008. An input distance function is estimated by true random effects (TRE). In addition, the change in total factor productivity in the period and its decomposition into different sources is obtained. The results indicate that, in average, operating cost efficiency showed an annual increase of over 2%, controlling for indicators of production, network dispersion and percentages of treated water. The estimated efficiency by TRE has a low correlation with that obtained by the traditional random effects model due to not assigning the heterogeneity to the constant of the model. In regard with TFP variation in the period, a significant reduction attributable to technical change and scale efficiency is observed; consistent with the low coverage rate of the sector. |

En este estudio se estima la eficiencia técnica de los costos de operación y mantenimiento de las prestadoras de agua potable y saneamiento en Brasil, utilizando los datos del Sistema Nacional de las Informaciones sobre Saneamiento (SNIS) durante 2004 y 2008. Se estima una función de distancia orientada hacia los insumos empleando el modelo de verdaderos efectos aleatorios (TRE). Adicionalmente, a partir de los resultados del modelo, se obtiene el cambio en la productividad total de los factores en el periodo y se efectúa su descomposición en diferentes fuentes. Los resultados indican que, en promedio, la eficiencia del costo operativo experimentó un incremento anual superior al 2%, controlando por indicadores de la producción y por la dispersión de la red y porcentajes de aguas tratadas. La eficiencia estimada por TRE presenta una baja correlación con la obtenida por el modelo de efectos aleatorios como resultado de asignar la heterogeneidad a la constante del modelo. En cuanto a la variación de la PTF, se aprecia una significativa reducción atribuible al cambio técnico y a la eficiencia de escala, resultado coherente con la reducida tasa de cobertura del sector.
