With a per-worker production function y = k1/2, the steady-state
capital stock per worker (k*) as a function of the saving rate (s)
is given by:
A) k* = (s/
)2.
B) k* = (/s)2.
C) k* = s/.
D) k* =
/s.
Answer is A, I need to understand the process. Thanks

Let yp(y) be the C(2) inverse demand function facing a monopoly, where y++ is its rate of output, and let yC(y) be the C(2) total cost function of the monopoly. Assume that p(y)>0, p'(y)<0, and C'(y)>0 for all y++, and that a profit maximizing rate of output exists. Total revenue is therefore given by R(y)=p(y)y. Given that question uses an inverse demand function, the elasticity of demand, namely (y), is defined as (y)= 1/p'y p(y)/y. Why is (y)<0? Prove that...

2. Consider the undamped oscillator equation dy + 9y = cos(wt) dt2 y(0) = 0 v(0) = 0 What is the steady state frequency of this system? Use your solver to solve this ODE for w=4, w= 3.1, w = 3.01 and w 3. Comment on what the solutions look like as you change w. What happened with the last solution? I
