Assume that the population does not grow. What is the steady-state of capital per worker, k*, and output per worker, y*? What happens to the steady-state values if the population growth rate rises to 5%? By how much would the country have to increase its savings rate in b) in order to reach the same levels of steady-state values as in a)? Does the country’s growth rate increase in c) compared to a)? how?Assume that an open economy with a floating exchange rate is described by the equations:C = 0.5(Y-T)T= 1000I= 1500 -250rG= 1500NX= 1000 – 250e(M/P)d = 0.5Y – 500rM= 1000S-I= 500 – 250rP= 2r* = 1 a.
