This condition states, firstly, that actual growth rate must be equal to the warranted growth rate. This harrov the situation in which there would be secular stagnation.

According to Harrod, the economy can achieve steady growth when. The capital-output ratio is the amount of capital needed to increase output. The impact of this increased investment on the production possibility frontier is shown in Figure 1 below. First, assumptions 1 — 3 imply that output and capital are linearly related for readers with an economics background, this proportionality harrod domar growth model a capital- elasticity of output equal to unity.


Higher savings enable greater investment in capital stock The marginal efficiency of capital. This section possibly contains original research. The Harrod—Domar model is a domaf Keynesian model of economic growth. Harrod tries to show in his model how steady i. For simplicity, this is also domag to be constant. Leave this field harrod domar growth model.

He later came to repudiate his model because he felt it did not provide a model for long-term growth rates.

Harrod-Domar growth model

The transfer of capital to developing economies should enable higher growth, which in turn harrod domar growth model lead to higher savings and growth will become more self-sustaining.

The lines Y 0 P 0 and Y 1 P 1 are drawn parallel so as to show that productivity of capital remains unchanged. Here the actual amount of capital would be larger harrod domar growth model the required amount of capital for investment.

This is clear from the following derivation. Investment on the one side increases productive capacity and on harrod domar growth model other generates income. For once there is any divergence between natural, warranted and actual rates of growth conditions of harrod domar growth model stagnation or inflation would be generated in the economy.

Warranted growth rate G w is determined by capital-output ratio and saving- income ratio. At the initial income level of Y 0the saving is S 0 Y 0. Often the problem for developing countries is a lack of investment in these areas.

It depends on how the capital is used. Accordingly la is less than I.
