Exploring the dynamic effect of economic growth on carbon dioxide emissions in Africa: evidence from panel PMG estimator.

The relationship between economic growth and environmental pollution continues to attract significant research interest for researchers, practitioners, and policymakers all over the globe. Theoretically, the environmental benefit of economic growth should be greater than its negative externality with higher level of development. However, from the African perspective, countries with higher economic performances often face several environmental challenges, which raises the doubt whether economic growth helps or constrains environmental quality improvement.

CO emissions and economic growth: Assessing the heterogeneous effects across climate regimes in Africa.

Climate change has occasioned several Earth long-term events, including extreme temperatures. In recent years, Africa was reported as part of the world's regions that experienced extreme temperatures above pre-industrial levels. Despite lower contribution to Green House Gas (GHG) emissions and global warming, Africa remains among the world regions that suffer the most from climate change.

Co2 emissions and economic development in Africa: Evidence from a dynamic spatial panel model.

The nexus between environmental degradation and economic growth continues to generate growing interest from environmental practitioners, industrialists, and researchers. Most existing studies in Africa have investigated the relationship based on the Environmental Kuznets Curve (EKC) theory under assumptions of homogeneity and spatial independence. In contrast, we investigate the EKC theory under more realistic possibilities of country heterogeneity and spatial dependence.

The effects of inequality on total factor productivity across districts in South Africa: a spatial econometric analysis.

This study builds on the fundamentals of the new economic geography and the skill-biased technological change argument, to empirically investigate whether increasing income/earning inequality enhances total factor productivity in South Africa. In so doing, panel data of district-municipalities and spatial econometric techniques are used for the period between 1995 and 2015, to gain a better understanding of the role of location and distance in the effects of income inequality on total factor productivity. The results from the analysis and empirical estimations indicate that: (1) there is strong support for the existence of positive spatial interactions in the effects of income inequality on total factor productivity; (2) the estimated direct effect of income inequality on TFP in local district-municipalities is negative and statistically significant, while the indirect effect is positive and statistically significant as well.
