An economy has the following characteristics. All values are in $millions.[14 marks]
C = 120 + 0.9YD
YD = Y + TR - T
T = 100 + 0.1Y

G = 600
TR = 200
X = 700
IM = 300 + 0.2Y
Where C is consumption, YD is disposable income, T is taxes, TR is transfer payments, I is investment, G is government expenditure, X is exports and IM is imports.
