1. Suppose that the production function of an economy is characterized by the following
Cobb-Douglas production technology Y = Ka L*1, where Y is the aggregate output, K
is the capital stock, L is the labor and 0< a <1.
a Assuming dosed economy with no govemment, labor growth rate being constant
(gs) and depreciation rate is positive ô > 0, show the step-by-step derivation of
the fundamental equation of growth (using per worker capital, k). Hint: First
derive per worker production function.
b. Find the steady-state values of capital per labor (k), output per labor
(), and consumption per labor (c). Hint: use the fact: k= 0.
What would be the effect of changes in s, gs and a on kf
2. Recall that general form of fundamental equation of growth in Solow model is
described as follows:
k = s - f(k.) – (gs + 6)ka
Noting that at steady-state kss = 0 and hence
a Using the fact kes= 0, show the steady-state graphically and provide economic
interpretation of the steady-state condition s- f(k s) = (gs + 6)k *
b Using the same graph you draw in part (a) explain the transitional dynamics of
the Solow. Hint: Defime what happens if k. <k s
and if k- > k s-
3. Assume that production fumction takes the form Y = (K'0.5) + L'as)E, Show if
this production function obeys neoclassical assumptions.
4. Lets assume that the time derivative of a continuous variable Xa is defmed as
X = M+N
where, M: and N: are also continuous variables defined by following functions:
N: = ekt & M, = et and k is a constant. Find the grow th rate of x at the steady state
in terms of k.
