Empirical assessment of the competitive conduct of Nigerian banks in a post-consolidation era

Abstract

This paper is an empirical assessment of the level of competition in the Nigerian banking industry following the consolidation exercise, using a bank-level panel data, for the period 2005–2014. Empirical evidence from the Panzar and Rosse (1987) H-statistic reveals that market power in the Nigerian banking industry is consistent with monopolistic competition, which implies that firms are independent in their decision-making and conduct. This study innovates by incorporating non-interest income accounts in the assessment of revenue, and findings suggest that bank competitiveness decreases as revenue tends toward an inclusion of non-interest income or fee-based services.
