The Solow–Swan model or exogenous growth model is an economic model of long-run economic growth. It attempts to explain long-run economic growth by looking at capital accumulation , labor or population growth , and increases in productivity largely driven by technological progress.
In the Solow growth model, a steady state savings rate of 100% implies that all income is going to investment capital for future production, implying a steady state consumption level of zero. A savings rate of 0% implies that no new investment capital is being created, so that the capital stock depreciates without replacement.
The Ramsey-Cass-Koopmans model does not have dynamic efficiency problems because agents discount the future at some rate β which is less than 1, and their savings rate is endogenous. The Diamond growth model is not necessarily dynamically efficient because of the overlapping generation setup. In a competitive equilibrium, the growth rate may ...
Nobel laureate Robert Solow, credited as the founder of the modern model of economic growth, died on Thursday at the age of 99. Through his writings in the 1950s, Solow challenged traditional ...

In the Solow-Swan model, economic growth is driven by the accumulation of physical capital until this optimum level of capital per worker, which is the "steady state" is reached, where output, consumption and capital are constant. The model predicts more rapid growth when the level of physical capital per capita is low, something often referred ...
The Solow–Swan model worked out by Robert Solow and, independently, Trevor Swan in the 1950s achieved more long-lasting success, however, and is still today a common textbook model for explaining economic growth in the long-run. [32] The model operates with a production function where national output is the product of two inputs: capital and ...
Trevor Winchester Swan (14 January 1918 – 15 January 1989) was an Australian economist.He is best known for his work on the Solow–Swan growth model, published simultaneously by American economist Robert Solow, for his work on integrating internal and external balance as represented by the Swan Diagram, and for pioneering work in macroeconomic modeling, which predated that of Lawrence Klein ...
