This book deals with the issue of convergence in efficiency levels among Indian public sector banks (PSBs) during the post-reforms. To accomplish the task of measuring technical efficiency for individual PSBs, we have used the increasing popular methodology of Data Envelopment Analysis. Further, we have utilized the traditional cross-sectional regression approach for investigating the presence of sigma- and beta-convergence in efficiency levels of PSBs. The empirical results indicate that the majority of PSBs have observed an ascent in technical efficiency during the post-reforms years. Further, the study confirms a presence of convergence phenomenon in the Indian public sector banking industry. This book will be useful for the research scholars intending to work on the efficiency and productivity analysis.
