Nudges in sustainable water management practices: Implementation, key findings and research agenda

Abstract

Nudging has emerged as an alternative policy for managing water demand in the residential sector. Indeed, numerous field studies have been recently published to assess the impact of nudges on water consumption. In parallel, a substantial body of literature has developed in the field of behavioral economics, including laboratory experiments to evaluate the effects of nudge-type or boost treatments on individual behavior. However, the corresponding results are frequently overlooked in field studies. In this context, focusing on the residential water sector, the aim of this survey paper are, first, to review field experiments and address key issues in behavioral economics; and second, to present results obtained from laboratory experiments that could enhance nudging policies. We conclude by discussing additional unexplored areas and their policy implications.
