Energy Consumption and CO2 Emissions Forecasting of Transport Sector Using Machine Learning

open access: yesEnergy Science &Engineering, EarlyView.
The transport sector accounts for approximately one‐quarter of Iran's final energy consumption. The energy demand in this sector has the least variation, with petroleum products accounting for more than 85% of the demand. Furthermore, the accelerated growth of energy consumption and the sector's reliance on fossil fuels, which are the main cause of ...

Revisiting the Nexus Between Trade Liberalisation and Income Inequality: The Case of Sub‐Saharan African Countries

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade
