Abstract
Evaluating the bank productivity over 2015-2019 with Data Envelopment Analysis (DEA) for 30 banks from eight developing countries is the main target of this study and in this correspondence, we have compared the productivities with Malmquist Productivity Index (MPI) which is very useful for managers for expanding their evaluation. The additive models are often named Slack Based Measure (SBM), and this group of models measures efficiency via slack variables. We evaluate the SBM Variable Return to Scale (SBM-VRS) and Constant Return to Scale (SBM-CRS). The results indicate that the SBM (VRS) model has the most productive effect during all periods compare with other suggested models in MPI. Meanwhile, SBM-CRS is in the second place. Input-oriented has been taken into account for the suggested models. The dataset has been acquired from BankFocus-Bureau van Dijk database.
