Abstract
Abstract The aim of this paper is twofold. First, we provide an empirical assessment of technical and cost efficiency based on a panel dataset of fourteen (14) Algerian commercial banks over the 2003-2012 period using the parametric technique of Stochastic Frontier Approach SFA and the non-parametric Data Envelopment Analysis DEA. Second, in a purpose to demonstrate the robustness of the obtained efficiency scores, we check the consistency conditions among the two frontier techniques by analyzing the correlation between efficiency estimates, rank order and the correlation with accounting measures of performance. Empirical results indicate the presence of a relative consistency between the two approaches in contrast with standard performance measures. We find that Algerian banks are efficient about 45,74 % (SFA) , and 62.60 % (DEA) in average, and efficiency scores vary according to the size and the ownership status . In fact, public banks outperform private banks affected by their high allocative inefficiency. We also notice that the Algerian banking efficiency has gradually deteriorated from 65,72 % in 2003 to 36,28 % in 2012.
