Malmquist indices of pre- and post-deregulation productivity, efficiency and technological change in the Singaporean banking sector

By the end of the 1990s, the Singaporean government had recognised the need to open up its banking sector so as to remain competitive in the global economy. The Monetary Authority of Singapore (MAS) thus began deregulation of the banking sector in 1999 to strengthen the competitiveness of local banks relative to their foreign competitors through mergers. This paper employs a nonparametric Malmquist productivity index to provide measure of productivity, technological change and efficiency gains over the period 1995-2005. The findings reveal some total factor productivity growth associated with deregulation and scale efficiency improvement largely from mergers amongst the local banks.Full Tex

Efficiency and productivity of Greek banks in the EMU era

We provide a characterization of the Greek banking system's efficiency and productivity under the new environment that the Economic and Monetary Union (EMU) participation implies. We consider cost and profit efficiency as well as productivity change of commercial banks using the nonparametric Data Envelopment Analysis (DEA) and the Total Factor Productivity (TFP) Malmquist Index. The period under study is 1998-2003 covering Greece's entry into the euro area in 2001 and the run-up to it. Moreover, enhanced competition along with lower inflation and interest rates has further motivated financial innovation and Off-Balance Sheet (OBS) business. Our findings suggest that cost efficiency has risen by 4.3% over the 6 years under study. Moreover, Greek banks seem to enjoy relatively high profit efficiency (on average 75%) showing an increase by 93% over 1998-2003. Similarly, productivity seems to have risen by 15% and this was mainly driven by the improvements in the performance of best-practice institutions. Our results do not show any role for OBS activities in Greek banks' efficiency. Finally, while the impact of profitability and size on efficiency and productivity yields mixed results, our empirical findings seem to corroborate previous studies in that controlling for risk preferences is important in determining bank efficiency
