ABSTRACT

This paper analyses the implications of cross-border banking (CBB) and institutional quality (IQ) for bank competition in Africa. It applies a two-step estimation procedure using bank-level panel data for 29 African countries. In step one, the Boone indicator and the Lerner index are used to gauge bank competition in a given country in Africa. In the second step, it analyzes the sources of bank competition placing emphasis on the impact of CBB and IQ. The results suggest that competition increased in the period of 2002–2005, before decreasing somewhat between 2006 and 2007 and increasing again thereafter. The results also show that cross-border banking enhances bank competition in African countries with stronger governance structures and institutional quality. These results are robust to an array of controls including an alternative methodology, variable specifications, and the regulatory environments that banks operate in.

摘要

本文分析了跨境银行业务 (CBB) 和制度质量 (IQ) 对非洲银行竞争的影响。它使用 29 个非洲国家的银行级面板数据应用两步估计程序。第一步，使用布恩指标和勒纳指数来衡量非洲特定国家的银行竞争。第二步，分析银行竞争的来源，重点关注CBB和IQ的影响。结果表明，竞争在 2002 年至 2005 年期间有所增加，然后在 2006 年至 2007 年之间有所下降，此后又再次增加。结果还表明，在治理结构和制度质量更强的非洲国家，跨境银行业务增强了银行竞争。这些结果对包括替代方法在内的一系列控制措施是稳健的，
