The debate on the nexus between energy consumption and economic growth continues unabated with divergent views on the direction of the relationship. This is partly due to the sources and patterns of energy consumption across different countries, differential characteristics of the economies, and differences in the methodologies employed. Again, the mixed and inconclusive results from prior cointegration tests might have arisen from the assumption of symmetry when, in actuality, the response of economic growth to energy consumption may be asymmetric. Furthermore, for studies that employed the asymmetric cointegration analysis, the data generating process might account for the conflicting evidence, especially for annual series. Therefore, this paper re-evaluates the relationship between energy consumption and economic growth in Nigeria over the period 1999Q1-2016Q4 using alternative model specifications. Specifically, the study used a nonlinear (or asymmetric) ARDL model and an ARDL-ECM specification which presumes a linear relationship rather than a nonlinear one. | Energy consumption and economic growth in nigeria A test of alternative specifications
