What is intertemporal substitution hypothesis?
The intertemporal-substitution hypothesis
attributes cyclical movements into and out of employment and cyclical fluctuations in hours worked by employees to optimizing labor-supply decisions in response

How do you calculate intertemporal elasticity of substitution?
This is straightforward to interpret.
Compute the percentage change in the ratio of marginal utility at i and j
that one percent change in the ratio of consumption at the same dates lead to. The inverse of the number is the intertemporal elasticity of substitution.
Who invented intertemporal choice?
For much of the twentieth century, the working model of intertemporal choice was the (exponential) discounted utility model developed by
Ramsey (1928) and Samuelson (1937)
, which features time-separable utility flows that are exponentially discounted: i.e., utility flows are discounted with the function , where …
What are examples of intertemporal decision making?
Most choices require decision-makers to trade-off costs and benefits at different points in time.

In deriving these conditions, the paper extends the notion of efficiency to an intertemporal Pareto-optimal concept requiring the maximization of the ith individual’s utility at a point of time subject to the constancy of his utility in all future periods and that of all other individuals during the relevant time span.
