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.
Robert Merton Solow, GCIH (/ ˈ s oʊ l oʊ /; August 23, 1924 – December 21, 2023) was an American economist who received the 1978 Nobel Memorial Prize in Economic Sciences, and whose work on the theory of economic growth culminated in the exogenous growth model named after him.
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 ...
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. [34] The model operates with a production function where national output is the product of two inputs: capital and ...
In 1957, Solow applied his model to data from the U.S. gross national product to estimate contributions. This showed that the increase in capital and labor stock only accounted for about half of the output, while the population increase adjustments to capital explained eighth. This remaining unaccounted growth output is known as the Solow Residual.
The 'Solow growth model' is not intended to explain or derive the empirical residual, but rather to demonstrate how it will affect the economy in the long run when imposed on an aggregate model of the macroeconomy exogenously. This model was really a tool for demonstrating the impact of "technology" growth as against "industrial" growth rather ...
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 ...
