An overlapping generations model, abbreviated to OLG model, is a type of economic model in which agents live a finite length of time long enough to overlap with at least one period of another agent's life.
All OLG models share several key elements:
- Individuals receive an endowment of goods at birth.
- Goods cannot endure for more than one period.
- Money endures for multiple periods.
- Individual's lifetime utility is a function of consumption in all periods.
The concept of an OLG model was inspired by Irving Fisher's monograph The Theory of Interest. Notable improvements were published by Maurice Allais in 1947, Paul Samuelson in 1958, and Peter Diamond in 1965.

“The principle goal of education in the schools should be creating men and women who are capable of doing new things, not simply repeating what other generations have done; men and women who are creative, inventive and discoverers, who can be critical and verify, and not accept, everything they are offered.”
