CONSTANT DISCOUNTING, TEMPORAL INSTABILITY, AND DYNAMIC INCONSISTENCY IN DENMARK: A LONGITUDINAL FIELD EXPERIMENT
通过丹麦全国代表性样本的纵向实地实验，检验了个人贴现率是否随时间稳定以及偏好是否动态一致，发现总体层面不能拒绝恒定贴现，但拒绝了时间稳定性和动态一致性。
Abstract Claims that individuals have dynamically inconsistent preferences are usually made by studying individual discount rates over different time delays, but where those discount rates are elicited at a single point in time. However, to test dynamic inconsistency one has to know if the same subject has a different discounting function at a later point in time . We evaluate data from a longitudinal field experiment undertaken with a nationally representative sample of the adult Danish population. We cannot reject the hypothesis of constant discounting at the population level, but we reject the hypotheses of temporal stability and dynamic consistency.
