Question: All units are given in $ million. C= 800 + 0.5Y D I= 100 T = 80 G = 200 Refers to below C =

All units are given in $ million.

C= 800 + 0.5YD

I= 100

T = 80

G = 200

Refers to below

C = Consumption expenditure, I = Gross investment, T = Income tax, G = Government expenditure, AE = Aggregate expenditure, YD = Disposable income
