This paper presents a systematic application of Data Envelopment Analysis in estimating
the relative efficiency of the branches of a Greek Bank. Three different main approaches were
used according to the choice of how to measure the flow of services (outputs) provided by Bank
branches. The three approaches were compared by applying all to the same data set of bank
branches. Little differences were found in the distribution of efficiency estimates. Overall, this
comparative study reveals that inferences regarding efficiency may be affected by how output
is measured.
