Growth models
| Model name | Endogenous variables | Exogenous variables | Constants | Year introduced |
|---|---|---|---|---|
| Harrod–Domar | 1939 | |||
| Solow–Swan | 1956 | |||
| AK | ||||
| Leontief input–output | ||||
| Feldman–Mahalanobis | ||||
| Becker–Barro | 1981, 1989 | |||
| Ramsey–Cass–Koopmans | ||||
| Romer | 1990? | |||
| Schumpeterian | ||||
| Product-variety | ||||
| Semi-endogenous (Jones) |
| Production function name | Models that use this production function |
|---|---|
| Cobb–Douglas | Solow–Swan |
| Leontief |
Probably for each model, a table like this:
| Name | Variable | Unit | Rival input? | Endogenous? | Notes |
|---|---|---|---|---|---|
| Output | Y | – | Yes | ||
| Physical capital (capital stock) | K | Yes | In Solow–Swan | Physical capital includes things like machines, computers, buildings, etc. | |
| Labor | L | Yes | Exogenous in Solow–Swan | ||
| Technology (knowledge) | A, T | No | Not in Solow–Swan | ||
| Consumption | C | ||||
| Investment | I | ||||
| Amount saved | S | ||||
| Growth of X | |||||
| Population growth | |||||
| Depreciation (rate?) | δ, d, D | ||||
| Capital per worker | k = K/L | In Solow–Swan | |||
| Fraction saved | s | ||||
| Output per worker | y = Y/L | Yes | |||
| Time | t | ||||
| Production function | F | ||||
| α |
