Consider an economy with the following information:
S-40+.10 Yd
IM = 20+.20*Yd
T = 60+.25*Y
I = 150
G = 200
X = 50
Notations and Definitions:
Ya = real disposable income = Y-T
Y real income
T= real net taxes
S = real private or personal saving = Y-T-C
C = real consumption
IM = real import
X = real export
NX = real net export = X - IM
I = planned real investment
G = real government purchases
PE = planned real expenditures =C+I+G+NX
