Use the Solow growth model seen in Mankiw, Romer, and Weil (1992). Assume that the production function is the same as equation
Y = KαH β (AL) 1−α−β
where K is physical capital, H is human capital, and AL is effective units of labor.
Solve for y which is defined as GDP per effective worker.

Consider a version of the Solow model where population grows at rate n
Q1)Consider a version of the Solow model where population grows at rate n. Assume that technology is Cobb-Douglas so that output is given by Yt = KtαLt(1−α).Capital depreciates at rate δ and a fraction s of income is invested in physical capital every period.A. Write down an expression describing capital accumulation in this economy and solve for the steady-state levels of capital and output per worker. Illustrate your answer in a diagram.B. How is steady-state capital per worker affected by...

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.

PLEASE provide an answer for Q2 and Q3 and their subquestions
Q2)Consider two imaginary countries, indexed A and B. Each economy can be characterised by the model above, but the population is constant in both economies. In the steady state, GDP per worker in country A is 1.44 times that of country B and the ratio of physical investment to output is 0.3 in country A and 0.25 in country B. The rate of depreciation is the same in both countries. What must α be in order for the model to...

Consider the Solow growth model. The production function is given by Y = K αN1−α , with α = 1/3. Depreciation rate δ = 0.05, and saving rate s = 0.25. Labor force grows at the rate n = 0.01. (a) Write down the law of motion for capital per worker. (b) Compute steady state capital per worker. (c) Suppose the economy has initial capital per worker k0 = 4. Describe the dynamics of this economy, i.e., how does capital...

Consider the two countries A and B above, but modify the model along the lines of Mankiw, Romer and Weil (1992) so that human capital, H, is included as a factor input. For simplicity, labour efficiency is assumed to be 1 in both countries. Output in country i is thus given by Yit=Kαit Hβit Li(1−α−β) and capital is accumulated according to ∆Kit+1= sikYit−δKit∆Hit+1=shYit−δHit where we note that sh is the same in both countries. a. Let y ≡ Y/L denote GDP per worker. Derive an...
