Economic growth is a necessary but not sufficient condition for development Savings and investment are a necessary but not sufficient condition for development On a practical level, it is difficult to stimulate the level of domestic savings, particularly in the case of developing countries where incomes are low. Although the Harrod—Domar model was initially created to help analyse the business cycleit was later adapted to explain economic growth.

However, the model has a range of problems as it tends to focus heavily on economic growth. Starting from the initial full employment level of income Y 0the actual growth rate G follows the warranted growth path Gw up to point E through period t 2.

Both the factors are used in the same proportion even when neutral technical takes place. Any increase in marginal propensity to save a will decrease the level of effective demand and vice versa. Ultimately, it will adversely affect the economy by lowering incomes and employment in the subsequent periods and moving the economy off the equilibrium path of steady growth.

Both these models stress the essential conditions of achieving and maintaining steady growth. Higher income allows higher levels of saving. This harrod domar growth model dampens investment, output, employment and income. But Harrod regards the level of income as the most important factor in the growth process. At the level of income Y 0the saving is Y 0 S 0. Domar viewed growth from the demand as well as the supply side.

The actual growth rate fluctuates between these two limits.

Domar was writing during the aftermath of the Great Depression where he could assume there would always be surplus labour willing to hrowth the machines, but, in practice, this is not the case. The model suggests that the economy’s rate of growth depends on:. Neoclassical economists claimed shortcomings in the Harrod—Domar model—in particular the instability of its solution [5] —and, by the late s, started an academic dialogue that led harrod domar growth model the development of harrrod Solow—Swan model.

The actual growth rate may differ from the warranted growth rate. Similar harrod domar growth model the effect of the change in the real capital K on the supply of output.
