Efficiency of Indian Commercial Banks: The Post-Reform Experience from Mergers & Acquisitions


  • Bhattacharyya, Surajit
  • Chatri, Ankit


This paper explores the impact of M&A on technical efficiency of Indian commercial banks during the second decade of reforms. We use DEA to compute the relative technical efficiency of banks that participated in M&A activities. The technical efficiency is computed under both 'common' and 'separate' frontier with the assumption of 'constant' as well as 'variable' returns to scale. We also compare the post-amalgamation efficiency scores of the participating banks with that of a control group comprising of such banks that did not undergo any consolidation since 1991. Our results indicate evidence of efficiency gains for the merging and/or acquiring banks. At the same time there are banks that have experienced deterioration in their post-M&A average efficiency levels.
