An Evolutionary Perspective on the Economics of Energy Consumption: The Crucial Role of Habits

Abstract

The climate change issue imposes us not only to change the way we produce and convert energy but also to modify current energy consumption patterns. A substantial body of literature has shown that our behavior is often guided by habits. The existence of habits - not fully conscious forms of behavior - is important as it contradicts rational choice theory. Their presence thus calls for the setting of new instruments as it is difficult to expect consumers to be capable of exercising control over their consumption of energy in reaction to given incentives. This is further increased in our perspective where the current carbon-based Socio-Technical System constrains and shapes consumers' choices through structural, cultural, social and institutional forces. Habits being potentially "counterintentional," can be considered as a form of behavioral lock-in that may explain continued increase of energy consumption. Policies should thus specifically address the performance context of habits. © 2009, Journal of Economic Issues / Association for Evolutionary Economics.
