Research limitations/Implications- This study may be extended in various ways. Since, this study only covers a sample period of seven years which are 2004 to 2010, thus future research might cover more sample periods. Further studies could also take a bigger sample size by including broad sample size such as Asia countries.
Originality/values- This study identified the most and least efficient of 14 countries in MENA regions before and after financial crisis and the finding could be useful to regulators and the banks as a benchmark in operating the financial industries. This study may also improve the awareness among the least efficient banks to initiate the proactive measures in order to be sustainable in the industry
