Exploring the Effects of Green Finance on Inclusive Growth
This study examines the impact of green finance on inclusive growth in African countries from 2015 to 2024, focusing on transmission channels involving energy sources and institutional factors. Panel data from African economies are used to construct a multidimensional inclusive growth index based on income, education, health, electricity access and digital connectivity. Applying Driscoll–Kraay robust standard errors to address cross‐sectional dep…

The global outbreak of COVID‐19 disease had a significant impact on the entire globe. Such a notable public health event can be seen as a “black swan” that brings unpredictable and unusual forces into the economic context and that it could typically lead to a chain of adverse reactions and market disruptions. Hence, the purpose of this study is to examine how COVID‐19 affects the environment, health, and the oil and energy markets. To achieve thi…
