中文摘要
本研究考察影响睡眠选择的机制，并探讨承诺机制和货币激励能否用于促进更健康的睡眠习惯。为此，我们对大学生开展了一项田野实验，为其睡眠提供激励，并通过可穿戴活动追踪器、问卷调查和时间使用日记收集数据。货币激励能有效延长睡眠时长，且有证据表明该效果在激励取消后仍存在一定的持续性。我们发现了对承诺机制存在需求的证据。我们的结果与部分成熟型的时间不一致偏好和过度自信相一致，并对睡眠选择领域信息干预的有效性具有启示意义。
Abstract
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.
