Inclusive growth and environmental sustainability: the role of institutional quality in sub-Saharan Africa.

Abstract

Growth and environment literature has gained much attention in recent times. However, the emphasis was laid on the conventional economic growth or gross domestic product at the expense of the category of growth that is evenly shared and whose social benefits are far reaching than just an increase in the overall economic pie. It is on this note that the present paper looks at the type of relationship between growth and environment with particular emphasis on growth that is all inclusive. Data are sourced from World Governance and Development Indicators (WGI and WDI) and an index of inclusive growth constructed using principal component analysis (PCA). The findings indicate that institutional quality plays a major role in enhancing growth-environmental sustainability. The results further find a new phenomenon called environmental inclusive-growth Kuznets curve (EIKC) and added to the EKC debate. That is, at the early phase of inclusive growth, environmental degradation rises as well but environmental quality improves with the rise in inclusive growth at a higher phase of the relationship. The study recommends that policymakers should encourage the economies of sub-Saharan Africa to pursue inclusive growth and not compromise it for sustainability since sustainability comes later. Institutional quality which serves as a transmission mechanism in the study can as well be used as a robust and efficient structure to avoid adverse environmental externalities of inclusive growth.
