Abstract: This paper examines the impact and efficiency of Indian banks pursuant to merger and acquisition using data envelopment analysis. The impact has been studied by comparing the efficiency of merged banks three years before and after the merger. To validate whether change in efficiency of banks is due to merger effect, this study compares the efficiency of merged banks with non-merged banks. Further, through interval estimation, this paper provides how close or far away the banks are from the efficient frontier. It is observed that technical efficiency of merged banks deteriorated immediately after the merger and showed improvement from the third year of post-merger period. Further, the effect of merger and acquisition on the profitability and operational cost of merged banks, in general, is not significant during the initial phase of merger, i.e. initial three years.
