“…In such terms, certain insufficiencies in the accounting indicators approach to efficiency measurement can be eliminated and conclusions about the efficiency can be improved using the DEA approach. Application of the DEA methodology in efficiency measurement has a wide scope and has been used extensively to assess school efficiency [23,28]; hospital efficiency [13]; bank efficiency [1,4,12,14,15,17,19,20,21,22,24,25,26,27]; insurance company efficiency [9,10,15,18], etc. In reviewing the literature, the conclusion is that most studies deal with similar approaches in measuring the relative efficiency of banks over a period of time.…”
