(4) Consider a discrete-time Solow growth model characterized by the Cobb- Douglas aggregate production function:
Y=K^(\theta )N^(1-\theta )
where the technology level
(A)
is constant at one, and the population size N is constant. The parameter
\theta
is between zero and one. Share s of output
Y
is saved (invested, with the remainder consumed), and share d of capital K depreciates. Thus, capital evolves according to the following law of motion.
K^(')=(1-d)K+sY
(i) Find the steady state level of capital per person
