Intertemporal Choice

Definition of Intertemporal Choice§

Intertemporal choice involves making decisions regarding the allocation of resources, like money and time, at different points in time. It’s the economic concept that addresses how current decisions can preserve or enhance future financial opportunities. The theory suggests that individuals may either decide to consume now or save for greater consumption in the future.

Key Formula:
$$U(C_1, C_2) = U(C_1) + \frac{U(C_2)}{(1 + r)}$$
Where:

• $U$ = Utility
• $C_1$ = Consumption in the present
• $C_2$ = Consumption in the future
• $r$ = Discount rate
