Where STT is the order student number:
C= 100+STT + [ 0.50-STT*0.01 ] Yd
X=30+STT
1= 50-STT + 0.15 Y
G= 200+STT
M= 150+STT + 0.12 Y
T= 40+STT + 0.2 Y
STT= 30

Request:
a)
b)
Calculate the equilibrium output of the economy.
We have:
Cm1 = 97%
AI= 30+STT
A Tr = 100+STI
AG = -120+STT
ATx = 150-STT
A C' = SO+STT
AX= 40+STT
A M = -70+STT
Calculate the new equilibrium output of the economy.
c) Using the equilibrium output in sentence (a), if the potential output is 1000, what fiscal policy should the govemment adopt in order for the economy to achieve the above potential output (knowing that the govemment only use or G or 1).
d) If the goverment wants to spend 1200 without hurting the economy, what fiscal policy should the government introduce?
