In this paper we make a methodological analysis of the Error Components Frontier (ECF) panel data model performance based on Stochastic Frontier Analysis (SFA) method for cost efficiency benchmarking in the presence of small panels and outliers. By means of a set of simulations and a subsequent application to the Argentine banking sector during the period 2005-2014, we prove that under these conditions an SFA model may not be adequate for benchmarking. These results are relevant for the empirical literature since small panels with the presence of outliers represent classical scenarios in developing economies industries.
