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)
“Before I had my first child, I never really looked forward in anticipation to the future. As I watched my son grow and learn, I began to imagine the world this generation of children would live in. I thought of the children they would have, and of their children. I felt connected to life both before my time and beyond it. Children are our link to future generations that we will never see.”
—Louise Hart (20th century)
“... if we look around us in social life and note down who are the faithful wives, the most patient and careful mothers, the most exemplary housekeepers, the model sisters, the wisest philanthropists, and the women of the most social influence, we will have to admit that most frequently they are women of cultivated minds, without which even warm hearts and good intentions are but partial influences.”
—Mrs. H. O. Ward (1824–1899)
