Consider an economy at the steady state according to the Solow Growth Model with a per capita production function where n=0.04, d=0.08, and s=0.3. Suppose a change in the age profile of the population leads to a reduction of the savings rate to s=0.28. As a result,

		consumption initially falls and continues to decline until reaching the new steady state.
		consumption initially rises and continues to increase until reaching the new steady state. that is above the original.
		consumption initially rises but then decreases to a new steady state level of consumption that is below the the original.
		consumption initially falls but then increases to a new steady state level of consumption that is above the the original.

Expert Solution

Answer:

Given that:

Consider an economy at the steady state according to the growth model with a per capita production function .

Ans: (option 1) consumption initially rises and continues to increase until reaching the new steady state.

Explanation:

The economy starts with a steady state saving rate s and capital stock k*. If now the saving rate decreases from s to s', the investment curve i = sf(k) shifts downwards.

As soon as the saving rate falls, investment automatically goes down.
And since, Y= C+I, consumption rises as investment fall.
Also, since both capital stock and depreciation remain unchanged in a steady state, depreciation now exceeds equilibrium investment. As a result the capital stock continues to fall.
The process goes on until the economy reaches the new steady state, which has a smaller volume of capital k'* and lower level of output compared to that in the old steady state.
As soon as the new steady state is achieved, the economy stays there and the rise in consumption stops, consumption is now at a higher level.

Solow growth model: steady state. What does it mean for the economy to be in the steady state? How is the steady state determined? How does steady-state output per person depend upon the investment and depreciation rates? Explain why an increase in the investment rate raises steady-state y. What are the effects of a rise in TFP or a fall in the rate of depreciation on steady-state y?

According to the Solow model of growth, growth, in the long run (the steady-state), determine only by growth in technology. However, in the Solow model, there is nothing about how technology determined. 1. What factors do you think might affect technology in the long run? 2. Justify your answer and explain the implications to the growth in the long run.

1. Consider a Solow economy that is on its balanced growth path (at the steady state.) Assume for simplicity that there is no technological progress. Now suppose that the rate of savings increases. a. What happens to the balanced-growth-path values of capital per worker, output per worker, and consumption per worker?
