Artigo:

This paper presents the estimation of a cost efficiency stochastic frontier panel for a sample of the Brazilian electricity distribution sector, using in the main function explanatory variables of average operational cost of the companies, such as average salary, cost of energy purchased and volume of energy supplied. In the equation of inefficiency is tested the average duration of the supply interruption per year in hours (DEC) and the average frequency of the supply interruption per year (FEC), as well as the productivity in MWhs sold by employee.
