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.
