Residential and Industrial Energy Efficiency Improvements: A Dynamic General Equilibrium Analysis of the Rebound Effect

The aim of this paper is to investigate bi-directional spillovers into residential and industrial sectors induced by energy efficiency improvement (EEI) in both the short-and long-term, and the impact of nesting structure as well as the size of elasticities of substitution of production and utility functions on the magnitude and the transitional dynamic of rebound effect.Developing a dynamic general equilibrium model, we demonstrate that residential EEIs spillover into the industrial sector through the labor supply channel and industrial EEIs spillover into the residential sector through the conventional income channel. Numerical simulations calibrated on the U.S. suggest that not taking into account these spillover effects could lead to misestimating the rebound effect notably of residential sector EEIs. We also demonstrate how the size and the duration of the rebound effect depend on the elasticities of substitution's values. Numerical simulations suggest that alternative sets of value for the elasticities of substitution may give different sizable patterns of rebound effects in both the short-and long-term.In policy terms, our results support the idea that energy efficiency policies should be implemented simultaneously with rebound effect offsetting policies by considering short-and long-term economy feedbacks. As a consequence, they require considering debates about what type of policy pathways are more effective in mitigating the rebound effect.

Automated summary

The aim of this paper is to investigate the bi-directional spillover effects of energy efficiency improvement (EEI) in the short-term and long-term on the residential and industrial sectors, as well as the impact of nesting structure and the size of elasticities of substitution on the magnitude and transitional dynamic of rebound effect. The study finds that residential EEI spills over into the industrial sector through the labor supply channel, while industrial EEI spills over into the residential sector through the conventional income channel. Numerical simulations suggest that neglecting these spillover effects may lead to underestimating the rebound effect of residential sector EEI, and the size and duration of the rebound effect depend on the values of elasticities of substitution.
