Might a policymaker choose a steady state with more capital than in the Golden Rule steady state? With less capital than in the Golden Rule steady state? Explain your answers.

Expert Solution

If an economy starts with a steady state with more capital than it would have in the Golden Rule steady state, the appropriate course of action for the policymakers would be to reduce the saving rate in order to reduce the stock of capital.

When an economy starts with less capital than in the Golden Rule steady state, public policy can be used to raise the saving rate to reach the Golden Rule. In Fig. 4.10 the increase in the saving rate in time t0 leads to an immediate fall in consumption and a corresponding rise in investment.

With the passage of time as more and more investment occurs the economy’s capital stock continues to increase. With capital accumulation, output, consumption and investment continue to increase. The process comes to halt only when each variable reaches its steady state level.

Since the initial steady state was below the Golden Rule, an increase in saving ultimately leads to a higher level of consumption than what originally prevailed. However an increase in the saving rate can just enable an economy to move from one steady state to another.

This is known as the transitional dynamics of the Solow model.

In order to maximize the steady state level of consumption per worker, the Golden Rule steady state capital stock per worker (k*gold) satisfies the condition that the marginal productivity of capital at the k*gold capital level equals the depreciation rate . Graphically illustrate how to find the k*gold. (20 points)

Suppose the Canadian economy is currently in a steady state with less capital than in the Golden Rule steady state. Using a graph, show what happens to output, consumption, investment, and capital in the transition of the Canadian economy towards the Golden Rule steady state.

20. If the capital stock is ABOVE the Golden Rule level, an increase in the capital stock would A raise output less than depreciation B raise output more than depreciation 21. If the capital stock is ABOVE the Golden Rule level, an increase in the capital stock would A cause consumption to fall B cause consumption to rise 22. At the Golden Rule level of capital, A the marginal product of capital per worker equals the depreciation rate B the...

What is meant by the golden rule level of capital? Explain what condition on the MPK is required if we are to have the golden rule. Explain why this condition is necessary. Finally, true or false: over time, the Solow model predicts that the capital stock approaches the golden-rule level.

A) consider an economy that starts at a "per-person capital stock" above the golden rule level. in order to reach the golden rule one must what? -requite initially increasing consumption to decrease consumption in the future -require initially reducing consumption to increase it in the future -results in higher consumption at all times in the future -results in lower consumption in the future B) which of the following is a good explanation as to why the typical production function y=f(k,l)...

Calculate the Golden Rule capital-labor ratio. Do this for the model economy considered in problem 3 above. To answer this question it is helpful to know that the marginal product of capital is Fk(k, 1) = .3k to the power of −.7 This is problem 3 3. Suppose that three countries have the same technology and follow the logic of the Solow growth model. If country 1 always saves 10 percent of output (i.e s = .1), country 2 always...

Suppose that the the economy is in a steady state where the capital stock per worker is above the golden-rule level. Illustrate this situation. To obtain the golden rule steady state, how should house- holds change their rate of savings? Suppose that the saving rate decreases at time t0. On a graph plot c, k, and i against t and show how the economy adjusts between the original and the new steady-state. Briefly explain why each variable is changing in...
