摘要

储蓄行为是否揭示了与社会相关的时际偏好?关心下一代的人可能会对其他朝代赋予福利权重。通过将当代人对下一代的偏好分解为朝代和跨朝代部分,我们可以在储蓄模型中捕捉到这些关注。在这种偏好下,如果其他朝代的现任成员也有跨朝代的偏好,那么为自己的后代储蓄就会使他们受益。这些偏好的外部性意味着不能从储蓄行为中推断出与社会相关的时际偏好,储蓄行为所揭示的效用贴现率应该降低。当前储蓄的外部效应也会随着时间的推移而降低,这意味着从储蓄行为中推断出的跨时偏好与时间不一致。

Cross-dynastic intergenerational altruism

Does saving behavior reveal socially relevant intertemporal preferences? People concerned about the next generation as such might assign welfare weights on other dynasties. These concerns are captured in a model of saving by decomposing the present generation’s preference for the next into its dynastic and cross-dynastic components. With such preferences, saving for one’s descendants benefits present members of other dynasties if they also care cross-dynastically. These preference externalities imply that socially relevant intertemporal preferences cannot be inferred from saving behavior and that utility discount rates revealed by saving behavior should be lowered. The external effect of present saving also decreases over time, implying that intertemporal preferences inferred from saving behavior are time-inconsistent.

期刊介绍: The Journal of Environmental Economics and Management publishes theoretical and empirical papers devoted to specific natural resources and environmental issues. For consideration, papers should (1) contain a substantial element embodying the linkage between economic systems and environmental and natural resources systems or (2) be of substantial importance in understanding the management and/or social control of the economy in its relations with the natural environment. Although the general orientation of the journal is toward economics, interdisciplinary papers by researchers in other fields of interest to resource and environmental economists will be welcomed.
