It is the idea that the economic growth is dependent on capital-output ratio (k, calculated as: Total output produced/total capital invested i.e. efficiency) and the saving ratio of the population.
The assumptions it makes are:
- Output is a function of capital stock
- The marginal product of capital is constant.
- Capital is necessary for output
- The product of the savings rate and output equals saving which equals investment
- The change in the capital stock equals investment minus the depreciation of the capital stock
It states that
Rate of growth of GDP = Savings ratio/ Capital output ratio.
according to harrod domar model the level of savings remain constant to the proportion of income.Harrod-Domar model assumes a simple production function y=f(k), where k is capital
By the Harrod-Domar model, net investment should be greater than depreciation rate or there should be an increase in the productivity of the factors of production.
The Harrod-Domar model of economic growth emphasizes the relationship between investment, savings, and economic output, suggesting that a certain level of investment is necessary to achieve a specific growth rate. It posits that an increase in investment leads to an increase in income and output, with the growth rate dependent on the capital-output ratio and the savings rate. The model highlights the importance of maintaining a balance between savings and investment to ensure stable economic growth. However, it has been criticized for its simplistic assumptions and neglect of factors like technology and labor.

It assumes that savings and investment are all that is needed for growth. No diminishing returns to capital is an implicit assumption.

The Harrod-Domar model is represented by a simple diagram that illustrates the relationship between investment, savings, and economic growth. Typically, it features two curves: one representing the level of investment needed to achieve a certain level of GDP growth and another showing actual savings. The intersection of these curves indicates the equilibrium point where desired investment equals actual savings, leading to growth. The model highlights the importance of investment in driving economic expansion and the role of savings in financing that investment.
The Harrod-Domar theory is an economic model that explains how investment can lead to economic growth. It posits that the level of investment needed to achieve a certain growth rate depends on the economy's capital-output ratio and the savings rate. Essentially, it suggests that higher savings and investment lead to increased production capacity, thereby fostering economic expansion. However, it has been criticized for its simplicity and assumptions, particularly regarding the relationship between savings and investment.

well i think this model really addresses growth and not development. you need to ask yourself whether economic growth equates development. the third world in its developing state may not necessarily develop in the linear manner as suggested in this model. further, many of the third world countries are dependent on the first world so any form of economic growth usually does not translate into development as most of the money leaves these countries to support the economies of the north.
The modernization model is a theory that suggests that societies evolve from traditional to modern forms through a series of stages, typically including economic development, urbanization, industrialization, and social change. Proponents believe that societies progress through these stages in a linear fashion toward greater wealth, technology, and equality. Critics argue that the model oversimplifies the complexities of societal development and fails to account for differences in cultural context and historical circumstances.
