Answer:
a) given: f= 0.5, s=0.05
Let steady state unemployment rate be u
Then, u= s/(s+f)
u = 0.05/(0.55)
u = 0.09 or steady state unemployment rate is 9%.
b) steady state equilibrium implies that economy eventually reaches that level. If unemployment rate is 6% this year, economy is not in long run equilibrium. Therefore, it will lead to macroeconomic adjustments such that unemployment rate is 9% next year.
