Pendekatan Penawaran Agregat Dan Perbelanjaan Agregat (AS = AE)
C = 300 + 0.6 Y
I = 1500
Cari Y.
Y = C + I = 300 + 0.6 Y + 1500 = 1800 + 0.6 Y
1Y = 1800 + 0.6 Y
0.4 Y = 1800
Y = 4500
Pendekatan Suntikan Dan Bocoran (I = S)
S = −300 + 0.4 Y
I = 1500
Cari Y.
S = I
− 300 + 0.4 Y = 1500
0.4 Y = 1800
Y = 4500
