Bank consolidation and competitiveness: Empirical evidence from the Korean banking industry

摘要

The Korean government consolidated several banks following the Asian Financial Crisis of 1997-1998 to stabilize the financial market and to improve international competitiveness. This process has brought sound capital reserves, assets and profitability to the banking industry. However, due to the resulting increase in market concentration, this process has also produced concerns about the monopolistic and oligopolistic power of the banks. Recently, the growing concern within the government is the weakening of bank competition due to the sharp increase in market concentration. This study reviews and examines the status of bank consolidation and the competitive structure of the banking industry. The degree of competitiveness in the banking industry is analyzed using the Panzar and Rosse model with a non-structural approach and data from 1992 to 2007 (before the beginning of the 2008-2009 Global Financial Crisis). This time span is divided into a pre- and a post-bank consolidation period. The estimation results indicate that monopolistic competition in the market exists but that the competitiveness of the banks has improved with the increased market concentration. This finding contradicts previous beliefs regarding the increased risk and lower competition derived from a concentrated financial system.
