Abstract: This study analyses the cost-efficiency of Nigerian banks pre and post the consolidation period. The researchers account for bank heterogeneity using the Bayesian random frontier model, which in this context provides a better fit than the traditional stochastic frontier model. From the efficiency inferences, it is shown that the cost-efficiency of Nigerian banks has increased post the consolidation period to reach its highest average of 91.21% in 2007. The study discusses the potential impact of consolidation on the efficiency results and provides direction for future research.
