This paper examines the role institutional quality plays amongst the empirical drivers of income inequality in Africa. Using a dynamic two‐step difference GMM with robust standard errors over the period 1990–2017, we find no statistically significant effect of institutions in general, on income inequality. However, we find that institutional quality indicators such as control of corruption and the strict enforcement of the rule of law significantly reduce income inequality. We also find no statistically significant effects of the other institutional quality indicators such as government effectiveness, voice and accountability, regulatory quality and political stability on income inequality in our sample. We suggest that more premium be placed on corruption control and the stringent adherence to the rule of law in ensuring equitable distribution of income in Africa. Furthermore, we re‐echo suggestions that promote institutional development in Africa as institutions in general remain very weak.

非洲收入不平等的驱动因素：制度质量重要吗？

本文考察了制度质量在非洲收入不平等的经验驱动因素中所起的作用。使用1990-2017年期间具有稳健标准误差的动态两步差分GMM，我们发现总体上机构对收入不平等没有统计上的显着影响。但是，我们发现，诸如控制腐败和严格执行法治之类的机构质量指标可大大减少收入不平等。在我们的样本中，我们还发现其他机构质量指标（如政府效力，声音和问责制，监管质量和政治稳定性）对收入不平等在统计上没有显着影响。我们建议在控制腐败和严格遵守法治以确保非洲收入的公平分配方面给予更多的重视。此外，我们回响了一些建议，这些建议在总体上仍然很薄弱的情况下促进了非洲的体制发展。
