Economy-wide and manufacturing energy productivity transition paths and club convergence for OECD and non-OECD countries

This work aims at developing a further understanding of the transition dynamics of energy productivity for a sample of 33 countries – including 23 low to middle income non-OECD countries – over the period 1971 to 2008. The focus of this work is on economy-wide and manufacturing energy productivities. We employ two steps of analysis, a preliminary step using simple methods consisting of sigma and gamma convergence and a second step employing a recent clustering algorithm that sorts countries into clubs. That clustering algorithm identified four clubs for economy-wide energy productivity and six clubs for manufacturing energy productivity. The newly industrializing countries and OECD countries were members of the better performing clubs.
