Psychological and Biological Foundations of Time Preference
利用爱尔兰时间日记研究的新数据，结合心理测试、医学检测和实时生物追踪，发现财务折现率与未来后果考量、自我控制、尽责性、外向性、经验回避等心理变量以及心率变异性和血压等生物学指标相关。
This paper considers the relationship between the economic concept of time preference and relevant concepts from psychology and biology. Using novel data from a time diary study conducted in Ireland that combined detailed psychometric testing with medical testing and real-time bio-tracking, we examine the extent to which individual differences in financial discounting are related to underlying biological and psychological differences. The paper finds that financial discounting is related to a range of psychological variables including consideration of future consequences, self-control, conscientiousness, extraversion, and experiential avoidance, as well as being predicted by heart rate variability and blood pressure.
