Asymmetric Effects of Energy Efficiency on Manufacturing Output in Nigeria: A Nonlinear ARDL Approach

Fatai Afolabi Asimi, Olatokunbo Demola Salami & Abideen Adekunle Tijani · Journal of Energy Research and Reviews · 2026

The relationship between energy efficiency and manufacturing productivity is often assumed to be linear. Yet theoretical and empirical evidence suggest significant asymmetries: firms may respond differently to efficiency gains than to efficiency losses. This study investigates th...

Capital–Energy Substitutability and Labour–Energy Complementarity in Nigeria’s Manufacturing Sector: Evidence from a Translog Cost Function

Fatai Afolabi Asimi & Saheed Olayiwola · Journal of Energy Research and Reviews · 2026

Understanding the scope for substitution between energy and non-energy inputs is central to the design of energy taxes, subsidies, and environmental regulation. Using annual data for 1981–2023, this study estimates Allen (AES) and Morishima (MES) elasticities among capital, labou...
