Anomalies: Intertemporal Choice
研究了人们在跨期选择中不按市场利率或单一贴现率贴现货币流的多种情形，发现贴现率受金额大小、正负符号、时间延迟、选择框架等因素影响。
We examine a number of situations in which people do not appear to discount money flows at the market rate of interest or any other single discount rate. Discount rates observed in both laboratory and field decision-making environments are shown to depend on the magnitude and sign of what is being discounted, on the time delay, on whether the choice is cast in terms of speed-up or delay, on the way in which a choice is framed, and on whether future benefits or costs induce savoring or dread.
