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.

Famous quotes containing the words overlapping, generations and/or model:
“The absolute things, the last things, the overlapping things, are the truly philosophic concerns; all superior minds feel seriously about them, and the mind with the shortest views is simply the mind of the more shallow man.”
—William James (1842–1910)
“In a few generations more, there will probably be no room at all allowed for animals on the earth: no need of them, no toleration of them. An immense agony will have then ceased, but with it there will also have passed away the last smile of the world’s youth.”
—Ouida [Marie Louise De La Ramée] (1839–1908)
“Your home is regarded as a model home, your life as a model life. But all this splendor, and you along with it ... it’s just as though it were built upon a shifting quagmire. A moment may come, a word can be spoken, and both you and all this splendor will collapse.”
—Henrik Ibsen (1828–1906)
