The role of financial development on economic growth in the emerging market countries of the sub-Saharan African (SSA) region

Purpose: This paper aims to investigate the effect of financial development (FD) on economic growth and growth-enhancing transmission channels for the sub-Saharan African (SSA) region in three different periods: the pre-Millennium Development Goals (MDGs) era (1990–1999), during the MDGs (2000–2017) era and the main period (1990–2017). Design/methodology/approach: The study used the system generalized method of moments (SGMM) approach on 45 SSA countries from 1990 to 2017, using the data collected from the World Bank and the International Monetary Fund (IMF). Findings: The long-run effect of the study showed mixed results in pre-MDGs and during MDGs periods but was positive in the main period. For growth-enhancing transmission channels, the results were mixed, although in many cases, institutional (INST) quality, human capital (HC) and foreign direct investment (FDI) were the main transmission channels. Research limitations/implications: Some of the countries were dropped from the analysis due to data inadequacy. Practical implications: The empirical results of this study provide evidence that the financial sector has robust positive effect throughout 1990–2017. Furthermore, the financial sector depends on several factors to improve economic growth. The SSA region has to focus on improving HC, INST quality in terms of good governance and create environment that is attractive to FDI since they were the main growth-enhancing channels. Originality/value: Most of the studies in SSA countries assessed the direct effect of FD on economic growth without considering its transmission channels in different time frames. Moreover, they often used specific variables but not the financial index. This study extended the scope by considering various financial sector transmission channels, in different time periods and the financial index.
