Index Decomposition Analysis for Energy Sectors in Latvia

Lelde Timma, Dagnija Blumberga

Abstract

This study explores the causes of changes in energy intensity in Latvia by applying logarithmic mean Divisia index decomposition analysis for energy sectors. Analysis on the latest data (2008-2012) reveals if any technological or structural changes have occurred during and after economic downturn in Latvia. The results show that the reduction in energy intensity before the year 2008 can be largely attributed to decline in energy intensities within sectors, but the increase in energy intensity after the year 2008 is regarded to expansion of energy demanding sectors.
