Assessing the distributional effects of financial development on consumption-based carbon emissions in Sub-Saharan Africa: a quantile-based analysis

This study assessed the role of financial development (FD) and its distributional effects in explaining consumption-based carbon (ConCO2) emissions, in a framework that also examined the environmental Kuznets curve (EKC) hypothesis, in the context of 19 Sub-Saharan African countries. A composite index was used as measure of FD in a set of data spanning over the period 1995-2017, while controlling for population size (PS), energy intensity (EI) and natural resource rents (Nrr). Given that the variables deviate from expected normal distribution as adjudged by results of pre-estimation tests, the method of moments quantile regression (MM-QR) estimation technique was used to account for distributional effects of FD on ConCO2. Results of the fixed-effect regression based on Driscoll-Kray standard errors (FE-DK) which was validated by three other estimators (fully modified ordinary least squares (FMOLS), dynamic ordinary least squares (DOLS), canonical cointegration regression (CCR)) statistically provided support for FD, PS and EI as drivers of ConCO2. Distributional effects of this show that FD exerts significant positive effect on ConCO2 among countries in the higher quantiles, but insignificant positive effect among those at the lower quantiles. The model provided no support for the EKC hypothesis for SSA; policy implications of these results were presented.

Automated summary

This study assesses the role of financial development in consumption-based carbon emissions, taking into account the environmental Kuznets curve hypothesis. The results indicate that financial development, population size, and energy intensity are drivers of carbon emissions, with financial development exhibiting a significant positive effect on countries in the higher quantiles but not in the lower quantiles. The model does not support the environmental Kuznets curve hypothesis for Sub-Saharan African countries.
