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)...

Using a translog cost function, we first estimate the economies of scale and then calculate the bank-specific scale elasticities for Korean banks over the period 2007Q2 to 2011Q2. We find that all the National banks operate with significant economies of scale, with bank-specific scale...

This study investigates the trend of X-(in) efficiencies across Eastern European 2004-accession countries' banking industries over the period 1999 to 2003. We use Data Envelopment Analysis (DEA) estimators to obtain proxies for X-(in)efficiencies and we then analyse the inter-country industry...

The Italian saving bank industry has undergone fundamental changes in its operational structure due to new competitive pressures. The gradual opening up of the European banking market has meant that a study of different banking cultures within the EEC is both warranted and needed. This paper is...
