In the nation of Wiknam, the capital share of GDP is 40 percent, the average growth in output is 4 percent per year, the depreciation rate is 6 percent per year, and the capital–output ratio is 5. Suppose that the production function is Cobb–Douglas and that Wiknam has been in a steady state. (For a discussion of the Cobb–Douglas production function, see Chapter 3.)
c. Suppose that public policy alters the saving rate so that the economy reaches the Golden Rule level of capital. What will the marginal product of capital be at the Golden Rule steady state?
d. What will the capital–output ratio be at the Golden Rule steady state? (Hint: For the Cobb–Douglas production function, the capital–output ratio is related to the marginal product of capital.)
e. What must the saving rate be to reach the Golden Rule steady state?
Q3) a) at golden state
MPK = +n+g
now at steady state,output growth = n+g = 4%
So MPK = .06 + .04 = .1 = 10%
B) as
MPK = capital share*Y/K
So, MPK = .4*Y/K
(K/Y) *G= .4/.1 = 4
c) saving rate at golden level equals capital share = 40%

3. LaunchPad. In the United States, the capital share of GDP is about 30 percent, the average growth in output is about 3 percent per year, the depreciation rate is about 4 percent per year, and the capital-output ratio is about 2.5. Suppose that the production function is Cobb-Douglas and that the United States has been in a steady state. (For a discussion of the Cobb-Douglas production function, see Chapter 3.) a. What must the saving rate be in the...

In the nation of Wooknam, the capital share of GDP is 40 percent, the average growth in output is 5.0 percent per year, the depreciation rate is 7.0 percent per year, and the capital–output ratio is 4.5. Suppose that the production function is Cobb–Douglas and that Wooknam has been in a steady state. Round answers to two places after the decimal when necessary. b. In the initial steady state, what is the marginal product of capital (MPK)?
The capital share of GDP is about 40 percent, the average growth in output is about2 percent per year, the depreciation rate is about 3 percent per year, and the capital–output ratiois about 1.5. Suppose that the production function is Cobb–Douglas andin a steady state.a. What must the saving rate be in the initial steady state? [Hint: Use the steady-staterelationship, sy = (δ + n + g)k.]b. What is the marginal product of capital in the initial steady state?c. Suppose...
If the U.S. production function is Cobb–Douglas with capital share 0.3, output growth is 3 percent per year, depreciation is 4 percent per year, and the Golden Rule steady-state capital–output ratio is 4.29, to reach the Golden Rule steady state, the saving rate must be: A) 17.5 percent. B) 25 percent. C) 30 percent. D) 42.9 percent.
Assume that a country's production function is Y = AK0.3L0.7. The ratio of capital to output is 4, the growth rate of output is 3 percent, and the useful life of capital is 20 years. 'A' is a technology constant that contributes to GDP (Y). A = 1 a) What is the marginal product of capital in this situation? b) If the economy is in a steady state, what must be the saving rate? c) If the economy decides to...
An economy has a Cobb-Douglas production function: Y = K"(LE)!-a The economy has a capital share of 0.25, a saving rate of 40 percent, a depreciation rate of 3.00 percent, a rate of population growth of 0.75 percent, and a rate of labor- augmenting technological change of 2.0 percent. It is in steady state. b. Solve for capital per effective worker (k*), output per effective worker (y*), and the marginal product of capital.
15. Consider an economy, with a production function given by Y-AK03L07. This economy's annual GDP growth rate is 5%. Also assume that L and Kare both growing at annual rates of 2%. Calculate the growth rate of total factor productivity for this economy. a. 2.0% b. 3.0% 4.0% c. d. 5.0% 16. Suppose output is determined by a Cobb-Douglas production function Y=AK L1 Where 0ca<1. If total factor productivity (A) remains constant, but labour (L) and capital (K) inputs both...
An economy has a Cobb-Douglas production function: Y = K°(LE)1-a The economy has a capital share of 0.25, a saving rate of 43 percent, a depreciation rate of 3.00 percent, a rate of population growth of 4.25 percent, and a rate of labor-augmenting technological change of 3.5 percent.
