ارزیابی تجربی از رفتار رقابتی بانک های نیجریه در دوران پس از ادغام

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.
