Why Don’t We Sleep Enough? A Field Experiment among College Students
通过给大学生提供睡眠激励并追踪数据，发现金钱激励能有效增加睡眠时长，且部分效果在激励取消后仍持续，同时存在对承诺机制的需求。
Abstract This study investigates the mechanisms affecting sleep choice and explores whether commitment devices and monetary incentives can be used to promote healthier sleep habits. To this end, we conducted a field experiment with college students, providing them incentives to sleep and collecting data from wearable activity trackers, surveys, and time-use diaries. Monetary incentives were effective in increasing sleep duration with some evidence of persistence after the incentive was removed. We uncover evidence of demand for commitment. Our results are consistent with partially sophisticated time-inconsistent preferences and overconfidence and have implications for the effectiveness of information interventions on sleep choice.
