Macroeconomics equilibrium sum help...please..:(

[nusamax]

Y=E
Y=c+i+g+(x-m)

c= 100+0.8yd
i= 50
t= 60+0.2y
g= 78

x= 68.5
m= 1/8c

questions
1. find the macroeconomics equilibrium
2. find multiplier of this economy

please help

[Nash']

Y = E (macroeconomics equilibrium)
so.. Y = C+I+G+(X-M)

 

[Nash']

Y = 100+0.8(y-t) + 50 + 78 + (68.5 - 1/8c)

 

[Nash']

C = 100+ 0.8 (y- (60 + 0.2y)
C = 100 +0.8 ( y - 60 - 0.2y)
C = 100 + 0.8 (0.8y - 60)
C = 100 + 0.64y - 48
C = 52 + 0.64y

Y = E (macroeconomics equilibrium)
so.. Y = C+I+G+(X-M)

happata bola umba Prof. Jhon Nash da?

 

[Nash']

which means...all together...

Y = 180 + 0.64y + ( 68.5 - 1/8 C)

 

[Nash']

soo we found out wat C equlas to nuh...
so u use it here...n den get....

Y = 180 + 0.64y + ( 68.5 - ( 1 / (52 + 0.64y) ) )

 

[ndnk]

Multiplier=1/ (mps+mpt+mpm)

substitute those values to this

 

[vudara]

Its a simple question..

y=116+0.64y+154+(112.6-11.6-0.064y)
y=116+0.64y+154+(101-0.064y)
y=116+0.64y+154+(101-0.064y)
y=270+0.64y+101-0.064y
y=371+0.576y
y-0.576y = 371+0.576-0.576
4.24y = 371
4.24y/4.24 = 371/4.24
y= 875
