Modelling asymmetric price responses of industrial energy demand with a dynamic hierarchical model

Accounting for asymmetric price responses while modelling industrial energy demand is required for a good understanding of the long-run properties of energy demand. This is to prevent formulating energy related policies on incomplete information resulting from masking the impacts of long-run impacts of different phases of energy price. Hence, this paper explores the asymmetric price responses of industrial energy demand for a panel of 54 sectors across 34 countries over the period 2000–2014 using a dynamic hierarchical model. The empirical results from both the regional and sectoral analysis indicate a considerable heterogeneity in the estimated long-run elasticities and preference for using hierarchical model. Further, the estimated elasticities in general indicate that producers are more responsive to price increases than price decreases. In addition, empirical findings reveal that industrial energy demand is characterised by endogenous factors embedded in the asymmetric price effects. From a policy perspective, these findings provide an evidence of marked long-run impacts of energy demand (that are not observable from a traditional symmetric energy consumption pattern) required in formulating dependable energy policies. •There is a considerable heterogeneity in the estimated long-run elasticities.•Producers are more responsive to price increases than price decreases.•Industrial energy demand is characterised by endogenous price effects.
