Homework Answers

Answer #1

At steady-state, sk* = (δ+n)k*

k* = [s/(δ+n)](1/1-)

y* = [s/(δ+n)](/1-)

c* = (1-s)/[(s/δ+n)]

1. Given the values, steady-state consumption, c* = (1-0.2)/[(0.2/0.04+0.02)] = 0.24

2. steady-state capital, k* = [0.1/(0.04+0.03)]1/0.5 = 100/49 = 2.04

3. steady-state income, y* = [0.3/(0.04+0.02)]0.6/0.4 =  53/2 = 11.18

4. The real rental price of capital equals the marginal product of capital (MPK) in the steady state. And MPK = (δ+n) = (0.04 + 0.01) = 0.05.

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 is constant and that the level of output produced can be represented by the following production function: Y = AKαL 1−α where A = 1 and α = 0.5.

Consider the Solow grow model. Suppose for each unit of savings, the government consumes a fraction τ , so only the fraction 1 − τ would accumulate the capital stock. In other words, the law of motion for capital becomes: K1= (1 − δ)K + (1 − τ )sY where δ is the depreciation rate, s is the saving rate, and Y is aggregate output. Suppose production function is Y = zF(K, N). Follow the same steps we did in...

Answer the following questions using the basic Solow growth model, without population growth or technological progress. (a) Draw a diagram with per worker output, y, consumption, c, saving, s and investment, i, on the vertical axis and capital per worker, k, on the horizontal condition. On this diagram, clearly indicate steady-state values for c, i, and y. Briefly outline the condition that holds in the steady- state (i.e. what is the relationship between investment and the depreciation of capital?). (b)...
