New Working Paper on Rebound Effects

This new study estimates the combined direct and indirect rebound effects from various types of energy efficiency improvement by UK households. In contrast to most studies of this topic, Mona Chitnis and Steve Sorrell base their estimates on cross-price elasticities and therefore capture both the income and substitution effects of energy efficiency improvements. This approach involves estimating a household demand model to obtain price and expenditure elasticities of different goods and services, utilising a multiregional input-output model to estimate the GHG emission intensities of those goods and services, combining the two to estimate direct and indirect rebound effects, and decomposing those effects to reveal the relative contribution of different mechanisms and commodities. The authors estimate that the total rebound effects are 63% for measures that improve the efficiency of domestic gas use, 53% for electricity use and 46% for vehicle fuel use. The primary source of this rebound is increased consumption of the cheaper energy service (i.e. direct rebound) and this is primarily driven by substitution effects. The results suggest that the neglect of substitution effects may have led prior research to underestimate the total rebound effect. However, the paper provides a number of caveats to this conclusion, as well as indicating priorities for future research.
