Stock market development and economic growth in sub-Saharan Africa (1990–2020): an ARDL approach

Abstract

Purpose

The purpose of this paper is to investigate the short and long run causal relationship between stock market development and economic growth in sub-Saharan Africa within the period 1990 and 2020.

Design/methodology/approach

Using panel data from 1990–2020 obtained from the World Bank development indicators, the study makes use of the autoregressive distributed lag model and the Granger causality and cointegration to analyze the long and short run causal relationship between stock market development and economic growth in sub-Saharan Africa.

Findings

The findings unveiled that stock market capitalization had a positive and significant effect on economic growth in the long run and a negative insignificant effect in the short run within the period of 1990–2020 while stock market liquidity measured through total value of shares traded and turnover ratio had a negative and significant effect on economic growth in sub-Saharan Africa within the period of 1990–2020. The Granger causality test showed an inconclusive result between stock market development and economic growth; implying that the authors cannot say if it is stock market development that causes economic growth or it is economic growth that causes stock market development within the period of 1990–2020.

Practical implications

The findings suggest that governments of sub-Saharan African countries should encourage stock market development by implementing favorable rules for companies listing on their stock market, promote stock market integration with world markets to diversify risk, increase public awareness on stock markets, increase investors' confidence level and finally, remove stock market impediments like high taxes, legal and regulatory barriers to its development.

Originality/value

This study contributes to the existing literature by offering a whole new perspective on stock market development and economic growth since its conception in sub-Saharan Africa. Again, contrary to other papers, the study show how stock market development can contribute to the growth of sub-Saharan Africans’ economy.
