Abstract

Este trabajo tiene como objetivo evaluar el desempeño en la eficiencia técnica de las empresas que distribuyen energía en Colombia durante el período 2004-2007, usando el análisis de frontera estocástica (SFA). Se emplea una función de distancia translog orientada a los insumos, lo que permite considerar a los productos como dados y a los insumos como variables de control. Los resultados empíricos arrojan que en el sector de distribución de energía no se generaron ni cambios tecnológicos ni mejoramientos en la eficiencia técnica durante el período de estudio. Además, se comprobó que las variables ambientales son determinantes de la tecnología de producción y en consecuencia se considera que el entorno en el que operan las empresas influye en su desempeño administrativo. Los resultados indican que cuatro de las empresas analizadas alcanzan una eficiencia técnica superior al 90 %. En general, el sector tiene una eficiencia técnica promedio de 60,12% y un componente de ineficiencia que representa el 94,50% del término de error compuesto; estas cifras indican que los errores aleatorios se deben, en gran medida, a la ineficiencia de las empresas.
