MORE EXERCISES 1. Transition dynamics: What is the principle of transition dynamics in the com- bined Solow-Romer model? 2. Long-run growth: Growth in the combined Solow-Romer model is faster than growth in the Romer model. In what sense is this true? Why is it true? 3. Balanced growth: Suppose we observe the following growth rates in various economies. Discuss whether or not each economy is on its balanced growth path. (a) A European economy: gy/l = 0.03,gkil = 0.03. (b)...
please show all work and solution in detail. Thank you
According to the Solow model, total equilibrium output is Y = A' 'Z(x/a) and per worker output is y = -5/). According to the Romer model, total equilibrium output is Y = A (1+g, (1-1) mnd per capita equilibrium output is y, = A. (1+2)/(1-7). Using each model, illustrate and explain what happens to the per worker output (*) if A, TFP in Solow or initial stock of ideas in...
Consider the Solow growth model with depreciation rate and population growth rate n. The equation of motion for the capital stock and the per worker production function in this economy are given by: Ak= s(f(k) - (8 + n) k y= f(k) = k1/4 a). Suppose adoption of modern birth control methods in a developing country causes the population growth rate to decrease. What happens in the main Solow diagram: what curve(s) shin, what happens to the steady- state level...
2. Consider the Solow growth model. Suppose that the production function is constant returns to scale and it is explicitly given by: Y = K L l-a a. What is the level of output per capita, y, where y = Y/L? b. Individuals in this economy save s fraction of their income. If there is population growth, denoted by n, and capital depreciates at the rate of d over time, write down an equation for the evolution of capital per...
Consider the Solow growth model. Output at time t is given by the production function Yt = AK 1 3 t L 2 3 where Kt is total capital at time t, L is the labour force and A is total factor productivity. The labour force and total factor productivity are constant over time and capital evolves according the transition equation Kt+1 = (1 − d) ∗ Kt + It , where d is the depreciation rate. Every person saves...
The Romer model consists of the following equations: Output production function: Y4 = A Lyt Idea production function: AA +1 = 2A Lat Resource constraint: Ly + Lat = L Allocation of labor: Lat = IL Suppose the parameters of the Romer model take the following values: Ao = 100, 1 = 0.06, 3 = 1/3000, L = 1000 18. What is the growth rate of output per person in this economy? a) 1% b) 2% c) 4% d) 10%...
Consider the Solow growth model. Output at time t is given by the production function Y-AK3 Lš where K, is total capital at time t, L is the labour force and A is total factor productivity. The labour force and total factor productivity are constant over time and capital evolves according the transition equation KH = (1-d) * Kit It: where d is the depreciation rate. Every person saves share s of his income and, therefore, aggregate saving is St-s...
4. A country is described by the Solow Model, with production function y - Aki where y is Output per Worker (Y/L) and k is Capital per Worker (K/L). Suppose k- 400. The fraction of output invested is 50% (s-05) and the depreciation rate is 5% (6-0.05). A, the overall productivity parameter equals 1. Is the country at its steady state level of output per worker, above the steady state or below the steady state? Show how you reached your...
Given the Solow model, a production function y = Ak1/3; depreciation =δ , and an investment rate=γ. (a) Draw the basic Solow model from class, labeling all lines, axes, and the steady state. (b) Start a new diagram. Assume a country in its steady state is hit by an earthquake that destroys physical capital but does not kill anyone. Draw a Solow model that describes the transition of the country from (1) its original steady state to (2) its immediate...
According to the Solow model, the variable that determines the steady state growth rate of output per worker (Y/N) is A) the savings rate B) the population growth rate the growth rate of effectiveness of labor D) the level of government expenditure
