Social psychology and environmental economics : a new look at ex ante corrections of biased preference evaluation
Environmental economics is now a long standing field of research ; much has been learned on how environmental policy can use incentives to drive individual behaviors. Among the many examples, preference elicitation is the most discussed case in which incentives fail to accurately implement efficient behavior. Using this as our motivating example, herein we explore the cross-fertilization between environmental economics and social psychology. We first review how the lessons drawn from social psychology helped address the hypothetical bias issue. We then turn to the future of this process by focusing on how cheap talk scripts influence preference elicitation. Our experimental results shows CT scripts work through persuasion – i.e. changes mind, but poorly changes actions. in that sense, preference elicitation still lacks a way of making communication binding – i.e. a way to alter intrinsic motivation of subjects to behave truthfully.
