Traditional economic theory well explains the tremendous fuelsubstitution during the 12 years of high energy prices from the year 1973to 1985, however, the observation that energy demand growth did notsurge despite the much lower energy prices since 1986 remains anunsolved puzzle. The past literature has evolved around three keyquestions -- is energy demand’s price responsiveness reversible, how bigis the rebound effect if it does exist, and can irreversible efficiencyimprovement better describe the irreversibility of energy demand.Digressing from the questions raised in the literature, this study attemptsto provide a theoretical justification for the observation of the reboundeffect. Built on the intertemporal optimization framework, the presentstudy constructs a theoretical model capable of examining the effect ofenergy efficiency improvements on energy consumption. Comparativestatics and dynamics analyses of a simplified dynamic production modelsuggest the existence of the rebound effect is actually in line with firms’intertemporal optimization behavior. |
