Productivity profiles of Islamic banks using data envelopment analysis-based Malmquist Productivity Indices (MPIs): Survey, classification, and critical analysis

This chapter surveys the literature on the productivity profiles of Islamic Banks (IBs), with a specific emphasis on Malmquist Productivity Indices (MPIs) estimated using Data Envelopment Analysis (DEA) methodologies. It examines 68 publications from 2006 to 2022, offering a comprehensive categorization of the literature based on four key aspects: (1) the type of DEA analysis, (2) productivity measurement methodologies, (3) variables for DEA model specification and corresponding evaluation approaches, and (4) the drivers of productivity along with their theoretical foundations. This paper also provides a critical analysis of the existing literature, identifying gaps, inconsistencies, and potential sources of discrepancies in the findings, thereby paving the way for future research to address these limitations.
