Abstract: This paper presents a bootstrapped efficiency score through estimating the DEA model. We focus on an input-oriented approach using returns to scale. By using input and output data on 20 Tunisian banks over the period 1990-2010, we construct more accurate bootstrapped confidence intervals; hence, we provide more reliable and useful results for decision-makers. Moreover, we find that 4 out of 20 Tunisian banks are perfectly efficient using a data-driven estimate of the smoothing parameter.
