4. Suppose that the Indonesian economy can be explained by the Solow model using thefollowing production function: Y = K (LE) ² , where E is the efficiency of labor.a. Derive the production function reflecting per-efficiency-unit-of-labor (in this case; y =fik) = Y/EL).b. Use the answer in (a) to find the steady-state value of y as a function of s, n , g, and d.c. Now suppose that the Malaysian economy also has the above production functions,but they have different parameter values. Indonesia has a savings rate of 28 percentand a population growth of 1 percent per year. While Malaysia has a savings rate of 10percent and a population growth of 4 percent per year. Both Indonesia and Malaysiahave g = 0.02 and d = 0.04. Determine the steady-state values of y in the two states.

Consider the basic Solow model with no population growth and no technological progress and a production function of the form F (K, H ), where H denotes the efficiency units of labor (human capital) given by where N is the set of all individuals in the population, and hi is the human capital of individual i. Assume that H is fixed. Suppose there are no human capital externalities and factor markets are competitive. (a) Calculate the steady-state equilibrium of this economy. (b) Prove that if 10% higher h at the individual level is associated with a% higher earnings, then a 10% increase in the country’s stock of human capital H will lead to a% increase in steadystate output. Compare this result to the immediate impact of an unanticipated 10% increase in H (i.e., consider the impact of a 10% increase in H with the stock of capital unchanged).
Suppose a Solow economy is initially at its steady state k∗, and suddenly is hit by a decrease in the depreciation rate δ, from δ to δ1. This change does not alter any of the other exogenous parameters in the model Depict this situation in a graph What happens to steady state level of capital per capita in this situation? What happens to the level of capital per capita over time? Depict this in a graph and explain intuitively.
B. The rate of technological progress rises. 2. Describe how, if at all, each of the following developments affects the break-even and actual investment lines in our basic diagram for the Solow model: a. The rate of population growth falls. B. The rate of technological progress rises. C. The production function is Cobb-Douglas, F(K,AL) = K" (AL)1-" , and capital"s share, ", rises. D. Workers exert more effort, so that output per unit of effective labor for a given value of capital per unit of effective labor is higher than before.
Assume that the economy’s production function is Cobb Douglas so per-capita output is ? = k^α, where k is per-capita capital. Using the Solow growth model, explain the impact of the loss of capital on the growth rate of per-capita output in the years following the disaster.
Suppose the economy of an island behaves as the Solow model (Y=AK1/2L1/2), version 1.0 (constant population). Suppose that the productivity parameter is A=90, the depreciation rate is d=1/10, the savings (investment) rate is s=0.10, and the labor force is equal to 2 million (and constant over time). 1-Due to climate change, from 2011 onward, every year the island is hit by hurricanes of increasing force that destroy capital. As a result, the depreciation rate doubles. What will be the new long-run (steady state) value for income per worker (Y/L)? Pick the closest value. Also label the new steady-state GDP as point C in the diagram. Between 75 and 85 None of the other options Between 4,500 and 5,200 Between 8,000 and 8,500 Between 44 and 49 2-In year 2021 investors recognize that the depreciation rate is higher than a decade earlier. They also recognize that the actual returns to their investments in physical capital over the previous decade have consistently fallen below their…
(a) Consider an economy that is initially in a steady state equilibrium. Assume that in this equilibrium it has a saving rate of 50 per cent and a depreciation rate of 2 per cent. Further assume that the population growth rate is 3% and that the level of output produced can be represented by the following production function: = where A = 1 and = 0.5. Use the Solow-Swan model to determine the level of capital per worker and output per worker in this economy. (1 mark) (b) Now suppose the government introduces a set of policies to improve the institutional set up as well as better production technique which increases total factor productivity by double. What is the new steady state level of capital per worker and output per worker? (1 mark) (c) Use a Solow-Swan diagram to show the qualitative effects of this new government policy upon steady state output per worker and capital per worker. Briefly describe the intuition behind this result. (1 mark) (d) Now suppose, population growth rate…
Q1. In the Solow model, suppose s=0.3, delta(depreciation)=0.05, output f(k) = sqrt of k. The economy starts at time t=0 with k=1. Suppose there is expropriation by the government and the entrepreneur only gets to keep 30% out its output. a) What is the capital per worker at time t=1? b) How does this compare with the case of no expropriation?
Suppose that we modify the Solow growth model by allowing long-run technological progress. That is, suppose that z = 1 for convenience and that there is labor-augmenting technological progress, with a production function Y =F(K,bN) where b denotes the number of units of "human capital" per worker, and bN is "efficiency units" of labor. Letting b' denote future human capital per worker, assume that b' = (1 + f ) b, where f is the growth rate in human capital. (c) In the real world, we usually consider education level as a proxy to human capital. To examine the theory, what suggestions can you make to growth economists? What are factors other than education can you think of that contribute to human capital?
Suppose the economy of Poorland is described by the simple Solow model without technological progress or population growth. The economy starts at the steady state. Suppose another country concludes that income per worker is too low in Poorland and therefore sends them at one-time development aid package (in form of capital) at period t0. a. Show what happens as a result of this aid package in a graph showing the production function, investment function and depreciation function (all in per-worker terms). b. Show a time path of output per worker that shows the old steady state, the change due to the aid package and the transition to the long-run equilibrium over time. Briefly explain your graph. c. If Poorland would like to maintain the capital stock per worker that it had right after the aid package was received, what would it need to do?
Consider the Solow model with a production function Y(t) = A*K(t)αL(t)1-α, Where A is a fixed technological parameter. Explicitly solve for the steady-state value of the per capita capital stock and per capita income. How do these values change in response to a rise in (a) the technological parameter A, (b) the rate of saving s, (c) α , (d) δ, the depreciation rate, and the population growth rate n?
Consider a Solow economy that begins with capital stock equal to $200 billion, and suppose itssteady-state level of capital is $400 billion. Now suppose this economy receives a gift of foreign aidin the form of $100 billion worth of capital.(a) Use the Solow model to explain what happens to capital per worker, output per worker, andconsumption per worker, both immediately and over time in this economy. (b) Suppose instead of starting below its steady state, the economy begins in steady state withcapital equal to $400 billion. Answer part (a) for this case. (c) In this example, does foreign aid have a long-run effect on the welfare of poor countries?
Consider the Solow model with a production function Y(t) = A*K(t)^α*L(t)^(1-α), Where A is a fixed technological parameter. Explicitly solve for the steady-state value of the per capita capital stock and per capita income. How do these values change in response to a rise in (a) the technological parameter A, (b) the rate of saving s, (c) α , (d) δ, the depreciation rate, and (e) the population growth rate n?
