Energy Intensity, Energy Efficiency and Economic Growth among OECD Nations from 2000 to 2019
This study examines the energy intensity (EI), energy efficiency (EE), and economic growth, measured by the type of returns to scale (RTS), of 37 nations in the Organization for Economic Co-operation and Development (OECD) from 2000 to 2019. We apply a non-parametric approach to estimate the three m...
