Financial development, financial structure and economic growth in the Sub‐Saharan African countries

Abstract

We use a financial development indicator to revisit the relationship of financial development and financial structure with economic growth. The financial development indicator simultaneously takes into account accessibility, depth and financial efficiency for the period 1980–2017 for Sub‐Saharan Africa countries. The continuously updated fully modified (Cup‐FM) and continuously updated bias corrected (Cup‐BC) estimators, as well as the panel smooth transition regression (PSTR), were used to examine the linear and nonlinear effects of financial development and financial structure on economic growth. For low‐income countries, the Cup‐FM and the Cup‐BC estimators indicate that the financial system relies on financial markets. The findings obtains through the PSTR model confirm this conclusion when the financial market represents more than 34% of financial institutions. For middle‐income countries, the Cup‐FM and Cup‐BC estimators reveal that the financial system relies on banking industry. However, this result is not supported by the PSTR model. In fact, it indicates that the financial system in these countries is based on financial markets when government expenditure as percentage of gross domestic product is less than 2.62%. Above this threshold, the financial system depends on the development of financial services, legal and regulatory framework.

Nexus between Governance Indicators & Sustainable Stock Market Development in Pakistan: Evidences from Symmetric and Asymmetric Analysis

“…The discussion indicates bi-directional causality between explanatory variables in case of Pakistan. The latest studies that support and wet this discussion include (Husnain et al, 2020;Lakshmi et al, 2021;Ouedraogo & Sawadogo, 2020;Uzum et al, 2021).…”

Triple vectorial analysis of financial development impact on economic growth: evidence from the Middle East and Central Asia

“…Ouedraogo and Sawadogo (2020) provide evidence that the market-based financial system improves economic growth in low-income countries, while the bank-based financial system improves economic growth in low-and middle-income countries of SSA. In the Chinese context, Liu and Zhang (2020) conclude that the effect of financial structure on economic growth depends on different stages of economic development.…”

“…(3) Government Final Consumption as % of GDP: It is intended to capture public expenditures that do not directly affect productivity but will entail distortions in private decisions. The coefficient associated with this variable is expected to be negative (Ouedraogo and Sawadogo, 2020).…”

“…(6) FDI as % of GDP: it represents the net inflows of investment to acquire a lasting management interest (10% or more of voting stock) in an enterprise operating in an economy other than that of the investor. It is included since the evidence shows a robust correlation of FDI growth to economic growth regardless of the information set (Omar Bakar et al, 2020;Omri et al, 2015;Ouedraogo and Sawadogo, 2020).…”

Assessment of financial system and economic growth: An empirical evidence from Ghanas stock market

“…The situation is not different with research on Sub-Saharan African (SSA) countries. Most African countries' financial systems are developed, and their structure totally relies on the banking industry with a more significant influence on the countries' economic growth at the total or partial neglect of the stock exchange market (Ouedraogo and Sawadogo, 2022). Notwithstanding the overemphasis literature on the impact of the banking industry as a pivot in the financial system on economic growth, there is strong evidence of the crucial role of an efficient stock exchange market in economic growth (Guptha and Prabhakar, 2018).…”
