Assume that an economy described by the Solow model is in a steady state with output and capital growing at 3 percent and labor growing at 2 percent The capital share is 0.4. The growth-accounting equation indicates that the contributions to growth of capital, labor, and total factor productivity are: Oa 1.2 percent, 1.2 percent, and 0.6 percent, respectively. O b. 3 percent, 2 percent, and I percent, respectively. O c. 0.4 percent, 0.6 percent, and I percent, respectively. O d. 0.4 percent, 0.6 percent, and 0.2 percent, respectively.

5. When was the Solow growth model developed and what was significant about that period? What did it predict that was significant at the time? When was the endogenous growth model developed? What did researchers observe the world that led to its development? What is the main feature that differentiates the two?

Answer all parts Suppose people can consume the income they earn or save and invest it at rate r?.A. If we tax wealth at a rate greater than r?, how are people likely to adjust their rate of savings? B. Use the Solow model to comment on how a wealth tax will likely affect the growth rate of the capital stock. How will this policy affect the growth rate of output per worker and how will this policy affect the wage rate for workers? C. To what extent is this wealth tax likely to reduce the influence of the wealthy in politics? D. In the Peterson Institute discussion, Greg Mankiw argues that accumulating wealth creates a pecuniary externality. What does Mankiw mean and how would you expect a wealth subsidy to affect the real wage for workers?
2. It is 1960. China's economy is in its steady state. It is predicted that the Chinese population will expand multi-fold over the next few decades. As an expert in economic growth, you have been called in to provide predictions about the economic effect of such population growth. a. Using the Solow diagram below, illustrate the effect on an increase in population growth on the post-1950 Chinese economy. у, і, б ہے k* Output Investment k Dep + Pop growth b. Explain (briefly) why this policy made sense to the government in 1960.

I need help with the questions and please prove justification.
If climate change impacts (e.g., increased heat waves, droughts, wildfires, etc.) decrease the economy's technology level A, then, through the lens of the Solow growth model (and assuming the economy was originally in a steady-state), holding all else constant, we would expect it to: O A. Decrease steady-state capital, decrease steady-state output, uncertain impact on steady-state consumption O B. Increase steady-state capital, increase steady-state output, uncertain impact on steady-state consumption OC. No impact on steady-state capital, decrease steady-state output, decrease steady-state consumption O D. Decrease steady-state capital, decrease steady-state output, decrease steady-state consumption If households are worried about climate change and this concern increases their savings rate, then holding all else constant (including A, so focusing only on the change in savings rates), we would expect it to: O A. Increase steady-state capital, increase steady-state output, decrease…
6. Using the Solow Model, determine graphically, the steady state for capital and output when there is an: (a) a permanent decrease in the savings rate (b) a permanent decrease in A (c) a permanent increase in the depreciation rate.
Consider the Solow growth model with no population growth and no tech- nology growth, i.e., n = x = 0. Output is created by a Cobb-Douglas pro- duction function combining Labor, Lt, and capital, Kt, such that output Yt is given by Y₁ = A+ KL-a = = 2. Recall that, without population growth, Lt = Lo and assume that Lo Furthermore, recall that, without technology growth, At Ao and assume that A0 = 1. Assume that the savings rate is s = 0.4, the depreciation rate is = 0.15, and that the capital share is a = 0.3. A lower case letter denotes a variable in per capita. For example, kt = K₁/Lt. In the following questions, choose the closest number. What is the value of kss? (a) 40.6 (b) 4.1 c) 2.8 (d) 28

which statement \s are true. use graphs to exlain a. In the Solow growth model, the saving rate is a crucial determinant of the economy's long-run growth rate of output per worker. b. In the endogenous growth model , the representative firm sets the wage so that the demand and supply of efficiency units of labour are equal. c. In the endogenous growth model , there is no steady state of the economy as human capital will always continue to grow forever. d. The assumption of Constant Returns to Scale technology implies that the marginal product of factor imput is always decreasing.
