Measuring Competition in Banking : A Disequilibrium Approach
AbstractThe "Rosse-Panzar" revenue test for competitive conditions in banking is based on observation of the impact on bank revenue of variation in factor input prices. We identify the implications for the H-statistics of misspecification bias in the revenue equation arising when adjustment towards market equilibrium is partial and not instantaneous. In simulation, fixed effects estimation produces a measured H-statistic that is severely biased towards zero. Empirical results for the banking sectors of six developed countries corroborate our principal finding, that a dynamic formulation of the revenue equation is required for accurate identification of the H-statistics.
