Happiness and Time Preference: The Effect of Positive Affect in a Random-Assignment Experiment
通过随机分配实验，发现轻微积极情绪显著降低人们对金钱的时间偏好，即更不倾向于现在而非未来获得收益，结果稳健且对情绪在经济决策中的作用有启示。
We conduct a random-assignment experiment to investigate whether positive affect impacts time preference, where time preference denotes a preference for present over future utility. Our result indicates that, compared to neutral affect, mild positive affect significantly reduces time preference over money. This result is robust to various specification checks, and alternative interpretations of the result are considered. Our result has implications for the effect of happiness on time preference and the role of emotions in economic decision making, in general. Finally, we reconfirm the ubiquity of time preference and start to explore its determinants. (DJEL D12, D83, I31)
