WORKING PAPERS
In economic theory, present biased preference, a dynamic inconsistent preference, implies that people want to deviate from their own plans that benefit them in the long-run. This paper develops a theory of optimally setting goals to counteract this bias and tests the predictions of the model in an online real-effort experiment. In our multi-selves model, the long-run self sets goals as reference points to motivate the short-run selves. Narrow bracketing is defined as setting one goal for each short-run self and broad goal-setting is defined as setting one broad goal for several short-run selves to jointly achieve. In line with the predictions of the model, the results of our online experiment show that 1) “Nudging” subjects to set narrow goals facilitates self-control. 2) The assumption that goals work as reference points is supported by empirical evidence. 3) Subjects who are more present-biased benefit more from goal-setting. 4) Broad goal-setting does not work. It also causes procrastination: subjects exert more efforts on the later date under it. 5) Surprisingly, but consistent with the model, we find that narrow goal-setting always outperforms broad goal-setting from the long-run self’s perspective regardless of the degree of present bias. However, the gap between the two bracketing methods shrinks as present bias decreases.
Responsibility Shifting through Delegation: Evidence from China's One Child Policy (joint with Yi Han) (pdf)
There is a growing body of experimental evidence indicating that delegation can foster the shifting of responsibility for unpopular actions from a principal to an agent. Using the well-known episode of the one-child policy in China, we provide first field evidence for responsibility shifting through delegation.
