Banking Competition and Macroeconomic Performance
Posted: 25 Aug 1998
This paper uses an equilibrium model to study the costs in terms of macroeconomic performance of imperfect competition in banking. The social welfare effects of increased bank competition are complicated and ambiguous in general, but measuring the consequences of increased bank competition with standard gauges of macroeconomic performance provides a clear conclusion: Increased bank competition raises the level of income and reduces the severity of business cycles. The quantitative effect on macroeconomic performance of less competition in banking can be large; for instance, an imperfectly competitive banking system can produce a worse macroeconomic outcome than if the economy had no banks.
