摘要

This study assesses how market power in the African banking industry is affected by the complementarity between information sharing offices and information and communication technology (ICT). The empirical evidence is based on a panel of 162 banks consisting of 42 countries for the period 2001–2011. Three estimation techniques are employed, namely: (i) instrumental variable Fixed effects to control for the unobserved heterogeneity; (ii) Tobit regressions to control for the limited range in the dependent variable; and (iii) Instrumental Quantile Regressions (QR) to account for initial levels of market power. Whereas results from Fixed effects and Tobit regressions are not significant, with QR: (i) the interaction between internet penetration and public credit registries reduces market power in the 75th quartile and (ii) the interaction between mobile phone penetration and private credit bureaus increases market power in the top quantiles. Fortunately, the positive net effects are associated with negative marginal effects from the interaction between private credit bureaus and mobile phone penetration. This implies that mobile phones could complement private credit bureaus to decrease market power when certain thresholds of mobile phone penetration are attained. These thresholds are computed and discussed.
