This paper examines the evolution of market structure in emerging markets during the 1990’s. While a significant process of bank consolidation has been taking place in these countries, reflected in a sharp decline in the number of banks, this process has not systematically been associated with increased concentration as measured by standard indices. Moreover, econometric estimates based on the ...

The 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-statistic of misspecification bias in the revenue equation, arising when adjustment towards market equilibrium is partial and not instantaneous. In simulations, fixed effects estimation produces a me...

This paper presents an empirical assessment of the degree of competition within the Jamaican banking sector during the period 1998 to 2007. The popular H-statistic by Panzar and Rosse is utilised to estimate market power among the sample of banks. Using usual statistical tests, we are unable to reject monopoly/perfect collusion for the banking market in Jamaica. This contrasts with earlier find...

This paper presents an empirical assessment of the degree of competition within the Jamaican banking sector during the period 1998 to 2009. We employ a dynamic version of the Panzar Rosse Model to estimate market power among the sample of banks that constitute over 90 percent of the banking market. Using the conventional statistical tests, we are unable to reject monopoly/perfect collusion for ...

The Panzar-Rosse test has been widely applied to assess competitive conduct, often in specifications controlling for firm scale or using a price equation. We show that neither a price equation nor a scaled revenue function yields a valid measure for competitive conduct. Moreover, even an unscaled revenue function generally requires additional information about costs and market equilibrium to in...

the iranian banking sector has undergone huge and substantial reform in the last decade; privatization, establishment of private banks and development of modern technologies (it). this paper investigates the competitive condition of the iranian banking industry over the period 2005-2010 using the h-statistic proposed by panzar and rosse. the properties of this non-structural methodology make it...
