The Asymmetric Nexus: Energy Efficiency and Total Factor Productivity in Nigeria’s Manufacturing Sector

This study examines the dynamic, non-linear relationship between energy efficiency and total factor productivity (TFP) in Nigeria's manufacturing sector from 1981 to 2023. Using a novel combination of Stochastic Frontier Analysis (SFA) and a Nonlinear Autoregressive Distributed Lag (NARDL) model, we uncover an asymmetric nexus in which improvements and deteriorations in energy efficiency have differential impacts on sectoral performance. Our findings reveal an average energy efficiency score of 82.2%, indicating significant potential for improvement. Crucially, we demonstrate that while effici…
