Introduction
The Solow-Hicks-Kaldor-Metcalfe sustainable growth model, introduced in 1956 by British economists Roy F. Harrod and Evsey Domar, is one of the leading models used to explain economic growth. This model is based on the idea that long-term economic growth can be achieved through capital accumulation and technological progress. It is also known as the Solow-Hicks-Kaldor-Metcalfe (SHKM) model, or the Solow-Hicks-Kaldor growth model.
The SHKM model has been used extensively in economic analysis and is one of the most widely accepted theories for economic growth. It is a simple model that explains economic growth as a function of only two factors: capital accumulation and technological progress. According to the SHKM model, economic growth is determined by two factors: the rate at which capital accumulates and the rate at which technology advances.
Capital accumulation
Capital accumulation is the growth of the total stock of physical capital available in an economy over time. The SHKM model states that the rate of capital accumulation is determined by the rate of investment in the economy. In other words, the model proposes that if the rate of investment increases, then the rate of capital accumulation will also increase, resulting in economic growth.
Technological progress
The SHKM model states that technological progress is the most important factor for economic growth. According to the model, economic growth is determined by the rate at which new technological advances occur. If the rate of technological progress is higher than that of capital accumulation, then economic growth will continue to increase.
Implications
The SHKM model has a number of implications for economic policy. First, it suggests that a government should focus on encouraging investment and promoting technological advances in order to achieve economic growth. Second, it implies that the government should aim to increase the rate at which capital accumulates, as well as promoting technological progress. Finally, it implies that the government should ensure that the incentives for investment are appropriate.
Conclusion
The Solow-Hicks-Kaldor-Metcalfe sustainable growth model is an important model for understanding economic growth. It suggests that economic growth is determined by the rate at which capital accumulates and the rate at which technology advances. This model has important implications for government policy, as it suggests that governments should focus on increasing investment and technological progress in order to achieve economic growth.
