Economic Growth and Environmental Quality: Analysis of Government Expenditure and the Causal Effect.

Environmental expenditures (EX) are made by the government and industries which are either long-term or short-term investments. The principal target of EX is to eliminate environmental hazards, promote sustainable natural resources, and improve environmental quality (EQ). Thus, this study looks at the impact of economic growth (EG), and government finance expenditure (GEX) on EQ in Northern Africa and Southern Africa (NASA) republics from 2000-2016. The panel quantile regression (PQR) and panel vector autoregressive (PVAR) model in a generalized method of moment framework (GMM) were employed as a framework. The PQR results show that; (i) In Northern republics, GEX had a significant positive effect on EQ at 25%, 50%, and 75% quantiles levels. (ii) In the Southern republics, GEX had a significant negative impact on EQ at 25%. Moreover, the PVAR through the GMM established that EG and GEX are significantly positive while the parameter for CO2 is insignificant and negative in the North. However, in the South, GEX and CO2 were statistically significant, while EG positively impacts EQ. Lastly, the granger causality report in North indicates uni-directional causation running from LNGEX → LNGDPpc, LNCO2 → LNGDPpc, LNFF → LNGEX, and LNFDI → LNGEX. Similarly, there is uni-directional causation in South republics from LNGEX → LNGDPpc, LNCO2 → LNGEX, and LNFDI → LNGEX.

The impact of banks' financial performance on environmental performance in Africa.

To better understand Africa's banks and the environment, this study investigates the impact of financial performance on environmental performance in Africa. We examined financial performance, environmental performance, and some control indicators dated from 2000 to 2016 by applying panel quantile regression and panel vector autoregressive techniques. Our results indicate that (i) in North African countries, carbon emission had a significant negative impact on financial performance on the 25th quantile and (ii) in the South, carbon emission had a statistically positive impact on financial performance on the 25th and 50th quantiles with the marginal effect increases from the lower quantile to the highest quantile. Also, bank deposits statistically negatively impacted financial performance on the 25th and 50th quantiles for both North and South economies. The dynamic panel quantile results show dissimilar effects at different quantiles. Also, the panel vector autoregressive results show that in North Africa carbon emission had a positive impact. Our results validate the stability test of the panel vector autoregressive model. The granger causality results in the North show a bilateral causal link between carbon emission and bank credit, carbon emission, and bank deposit. Since sustainability has become one of our era's most thorny issues, this paper provides extensive policy directives to assist African nations in boosting a greener future.

Financial development and environmental quality: the role of economic growth among the regional economies of Sub-Saharan Africa.

The Sub-Saharan African region is considered to be the most susceptible to the effects of climate change. The region's climate is influenced by several factors, the most notable of which is increased variation in development. The conglomerate between the financial sector and environmental quality (EQ) has been a priority for policymakers and analysts. This study looked at the complex relationships between financial development (FD) and environmental quality, as well as the position of economic growth (EG), from the perceptions of the five sub-national economies, from 1980 to 2017. The study tested the EKC hypothesis across the sub-regions. We employed the panel vector autoregressive (PVAR) model in a generalized method of moment framework to investigate the topic. The PVAR result showed that (i) financial development had a negative impact on CO2 in four geographical regions (Western, Southern, Northern, and Central). As a result, FD in these countries minimizes carbon emissions and enhances the atmosphere. (ii) Also, FD had a positive impact on carbon emissions in Western Africa. As a result, FD in these countries increases CO2 rather than improving environmental quality. The EKC hypothesis was validated in the Western African sub-region but was rejected in Central and Eastern (u-shape relationship) African sub-regional economies indicating variations in growth and environmental outcomes among the sub-regional economies. The Granger causality results in the West and Central African republics was a two-way causal connection between EG and CO2. The results demonstrate how "EG and CO2" and "CO2 and EG" are intertwined in Western and Central, while most of the relationships were unidirectional. Detailed sub-regional policy recommendations are deliberated.

Investigating the dynamic relationships between credit supply, economic growth, and the environment: empirical evidence of sub-regional economies in Sub-Saharan Africa.

Sub-Saharan Africa (SSA) is considered the most vulnerable to challenges emanating from climate changes. A number of factors notably accelerated changes in growth influence SSA environment. Linking financial sector within growth and environmental outcomes has been the focus of policy makers and researchers. This study investigated the dynamic relationships between credit supply, economic growth, and the environment from the perspectives of the four sub-regional economies (Central, East, Southern, and West African regions) in SSA over the period 1990-2018. In addition, the study tested Environmental Kuznets Curve hypothesis across sub-regions. We employed panel vector autoregressive (panel VAR) model in a generalized method of moment framework to investigate the topic. The panel VAR results revealed that (i) economic growth negatively influence on carbon emissions of Central African countries but not in the East, Southern and West African sub-regions, (ii) credit supply had significantly positive influence on carbon emissions and economic growth of Central and East African sub-regions but negative influence on carbon emissions and economic growth West African sub-regions in SSA, and (iii) carbon emissions had significantly negatively influence on credit supply of East and West African sub-regions. The granger causality results revealed bidirectional causal links between credit supply and carbon emissions, economic growth, and credit supply in the Central and East African sub-regions, while most of the relationships were unidirectional. The impulse response function revealed that the impact of one variable on another vary throughout the periods and across sub-regions. Similarly, the elasticity of the variables to each other varies across sub-regions over the period studied. EKC hypothesis was validated in East African sub-region but was rejected in Central (u-shape relationship), Southern, and West African sub-regional economies indicating variations in growth and environmental outcomes among the sub-regional economies. Specific sub-regional policy recommendations are discussed.
