Nudging and boosting reasonable use of public products: two experiments from China

Abstract Behavioral instruments have unique advantages in certain governance contexts for the reasonable use of public products. Drawing on bounded rationality, we compare two major behavioral instruments – nudging and boosting – and experimentally test their effectiveness in promoting reasonable use of public products. We select the default option (nudging) and future orientation (boosting) as specific instruments. In Study 1, we conduct a laboratory experiment and find that (1) both the default option and future orientation reduce free electricity usage; (2) the immediate effect of the default option is greater than that of future orientation, but its delayed effect is smaller; and (3) the combination strategy is more effective than any single intervention. In Study 2, we conduct a field experiment targeting reasonable use of public toilet paper and basically replicate the results of the laboratory experiment. These findings reinforce our confidence in the effectiveness of nudging and boosting and suggest the possibility of bridging behavioral science with governance theory.
