Abstract

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 findings using alternative estimators. Therefore, the use of a dynamic reformulation of the model with a dynamic estimator highlights some collusive behaviour among banks.
