An empirical investigation of capital flight and economic growth nexus in Africa

This paper investigates the impact of capital flight on economic growth in Africa using 54 African countries from 2000 to 2021. The study employed the GMM and the dynamic panel threshold regression estimation techniques. GMM results revealed that capital flight negatively and significantly affects economic growth in Africa. The study also revealed that external debt repayment and outward foreign direct investment, proxies of capital flight, have a negative and significant effect on economic growth in Africa, except foreign portfolio investment outflow, which positively and insignificantly influences economic growth. Again, the dynamic panel threshold estimation results also revealed that capital flight negatively affects economic growth at all levels of capital flight in Africa. The study also revealed that all the proxies of capital flight, external debt repayments, foreign portfolio investment outflows, and outward foreign direct investment negatively and significantly affect economic growth above a certain threshold. However, external debt repayment has an insignificant negative effect on economic growth below the threshold in Africa. Based on the findings, African countries should implement stringent policies to curb capital flight and regulate external debt repayments and outward foreign direct investment to enhance economic growth.
