Harrod Model in Dynamic Theory

Play an AI-generated podcast conversation about this lesson

What is the main focus of Harrod's model?

Harrod's model focuses on how steady growth and full employment can be achieved in an economy.

What are the three distinct rates of growth in Harrod's model?

The three rates are: 1) Actual growth rate (G), 2) Warranted growth rate (Gw), and 3) Natural growth rate (Gn).

What is the warranted growth rate (Gw) in Harrod's model?

The warranted growth rate (Gw) is the full capacity growth rate of income of an economy.

What does the natural growth rate (Gn) represent in Harrod's model?

The natural growth rate (Gn) represents the 'welfare optimum' or the potential/full employment rate of growth. Signup and view all the answers

What is one of the assumptions of Harrod's model?

One of the assumptions is that the level of ex-ante aggregate saving is a constant proportion of aggregate income. Signup and view all the answers

How does Harrod's model integrate the theories of 'multiplier' and 'accelerator'?

Harrod's model integrates the theory of 'multiplier' with the theory of 'accelerator' to explain investment and growth. Signup and view all the answers

What is the fundamental equation for actual growth rate (G) according to the text?

The fundamental equation for actual growth rate (G) is: G = √s, where s is the average propensity to save. Signup and view all the answers

What is the warranted growth rate (G_w) and how is it defined?

The warranted growth rate (G_w) is the rate at which producers will be content with what they are producing. It is the 'entrepreneurial equilibrium' where demand and supply of goods and services remain in equilibrium, given the propensity to save. Signup and view all the answers

What is the equation for the warranted growth rate (G_w)?

The equation for the warranted growth rate is: G_w * C_r = s, where C_r is the required capital-output ratio and s is the saving-income ratio. Signup and view all the answers

What condition must be satisfied for an economy to achieve stable growth according to the text?

For an economy to achieve stable growth, two conditions must be satisfied: 1) The actual growth rate (G) must be equal to the warranted growth rate (G_w), and 2) The capital-output ratio needed to achieve G must be equal to the required capital-output ratio to maintain G_w given the saving coefficient (s).

What is the natural rate of growth according to Harrod?

According to Harrod, the natural rate of growth is the trend in production with full employment and no inflation. Signup and view all the answers

What is the relationship between the warranted growth rate (G_w), the average propensity to save (s), and the capital-output ratio (C_r)?

The relationship is given by the equation: G_w = s / C_r. This implies that for full capacity utilization, income must grow at a rate equivalent to the average propensity to save divided by the capital-output ratio. Signup and view all the answers
