【摘要】：跨期决策中主要存在三个价值不对等现象:时间折扣、符号效应和过去、未来的价值不对等,上述不对等现象涉及到时间距离、时间方向和损益情境三个主要评价维度。本研究旨在通过实验考察时间距离、时间方向和损益情境在跨期决策中的相互作用。通过设置获益(中奖)和损失(罚款)的假想场景,要求被试对不同时间距离、不同时间方向上的决策任务作出判断,根据双曲模型,计算时间折扣率。结果,时间距离影响未来方向决策,而不影响过去方向决策;相同时间距离条件下,未来方向折扣率显著大于过去方向折扣率;损失折扣率大于获益折扣率,得到"反符号效应"。
[Abstract]:There are three phenomena of value inequality in intertemporal decision making: time discount, symbolic effect and value inequality in the past and future. The purpose of this study is to investigate the time distance through experiments. The interaction of time direction and profit and loss situation in intertemporal decision making. By setting up the scenario of gain (winning) and loss (penalty), the subjects were asked to judge the decision task in different time distance and different time direction. According to hyperbolic model, time discount rate is calculated. Results: time distance affects future direction decision, but does not affect past direction decision, under the same time distance condition, future direction discount rate is significantly higher than past direction discount rate. The loss discount rate is greater than the profit discount rate, and the reverse symbol effect is obtained.
