Perhaps the most important parameter in the Harrod—Domar model is the rate of savings. This implies capital’s marginal and average products are equal.
This section has multiple issues. The model carries implications for less economically developed countrieswhere labour is in plentiful supply mpdel these countries but physical capital is not, slowing down economic progress. Development economics Growth economics Monetary economics Political economy. Views Read Edit View history. First, assumptions 1 — 3 imply that harrod-doma and capital are linearly related for readers with an economics background, this proportionality implies a capital- elasticity of output equal to unity.
It suggests that there is no natural reason for an economy to have balanced growth.
CHAPTER 3: HARROD-DOMAR | Luis Corchon – testkey
The Harrod—Domar model is a classical Keynesian model of economic growth. These assumptions thus generate equal growth rates between the two variables. Please help improve this section by adding citations to reliable sources.
Natural growth is the growth an economy requires to maintain full employment. Let Y represent output, which equals income, and let K equal the capital stock. That depends on how much control the policy maker has over moxel economy. Redirected from Harrod-Domar growth model. A Survey of Contemporary Macrodynamics.
Increasing the savings rate, increasing the marginal product of capital, or decreasing the depreciation rate will increase the growth rate of output; these are the means to achieve growth in the Harrod—Domar model. The endogeneity of savings: This section possibly contains original research.
Harrod Domer Model
Although the Harrod—Domar model was initially created to help analyse the business cycleit was later adapted to explain economic growth. LDCs do not have sufficiently high incomes to enable sufficient rates of saving; therefore, accumulation of physical-capital stock through investment is low. S is total saving, s is the savings rate, and I is investment.
Can it be treated as a parameter that can be manipulated easily by policy? Statements consisting only of original research should be removed. According to the Harrod—Domar model there are three kinds of growth: Economics models Economic growth. Its implications were that growth depends on the quantity of labour and capital; more investment leads to capital accumulation, which generates economic growth.
In summation, the savings rate times the marginal product of capital minus the depreciation rate equals the output growth rate. The model implies that economic growth depends on policies to increase investment, by increasing saving, and using that investment more efficiently through technological advances.
Another criticism is that the narrod-domar implies poor countries should borrow to finance investment in capital to trigger economic growth; however, history has shown that this often causes repayment problems later.

It is used in development economics to explain an economy’s growth rate in terms gorwth the level of saving and productivity of capital.

The model concludes that an economy does not “naturally” find full employment and stable growth rates. The Harrod—Domar model makes the following a priori assumptions:.
Retrieved from ” https: This page gowth last edited on 26 Aprilat Neoclassical economists claimed shortcomings in the Harrod—Domar model—in particular the instability of its solution  —and, by the late s, started an academic dialogue that led to the development of the Solow—Swan model.
