Productivity changes and risk management in Indonesian banking: a Malmquist analysis

Abstract

In this study, we utilize a nonparametric efficiency measurement approach which combines the Semi-Oriented Radial Measure–Data Envelopment Analysis (SORM–DEA) approach for dealing with negative data (Emrouznejad et al., 2010) with the Slacks-Based Efficiency Measures (SBM) of Tone (2001, 2002) to analyse productivity changes for Indonesian banks over the period Q1 2003 to Q2 2007. The first part of the analysis showed that average productivity changes for the Indonesian banking industry tended to be driven by technological progress rather than by frontier shift, although a relatively stable pattern was exhibited for most of the period. With respect to the risk management analysis, most of the balance sheet variables were shown to have had the expected impact on Risk Management Efficiency (RME), with the state-owned grouping exhibiting the highest degree of RME and the listed and Islamic banks outperforming their nonlisted and conventional bank counterparts, respectively. A strategy based on the gradual ad...
