ENGLISH ABSTRACT: In light of the 2007/2008 global financial crisis, as well as pre- and post-crisis banking reform, this research investigated changes in competitive behaviour among banks in Sub-Saharan Africa, thus adding new insights to the current debate. The main findings from the empirical test were as expected and suggested conditions of monopolistic competition. In order to validate sufficient conditions for observing competition, an empirical test conducted to measure a state of general market equilibrium, had the expected outcome. Specifically, the research methodology applied the Panzar-Rosse model, a non-structural approach in the manner of the New Empirical Industrial Organisation. In the first instance, the model derived a continuous measure of a static H-statistic with a value of 0.57, using 481 bank-year observations from an unbalanced panel of 83 banks from six countries over the period 2008–2013. The H-statistic measured the degree of competition by explaining how changes in market power or unit factor input prices of funds, labour and capital expenditure influenced the pricing output of banks. A computed E-statistic, which was statistically equivalent to zero, validated the significance of the H-statistic, as the result implied that, in equilibrium, market power of a bank does not influence its returns. Overall, the findings were consistent with the pricing and strategy theories, such as contestable markets theory, which indicates that pricing power is associated with neither industry structure nor concentration, but instead with changes in input prices. In addition, the findings were consistent with relevant prior studies, which concluded that banking systems in parts of Europe, Asia, Latin America and Sub-Saharan Africa were monopolistic, and that banking reform influenced market discipline.
