11. The following aggregate expenditure flows are given for the
economy of Macroland. All figures are billions of Macro dollars.
Taxes: T=30
Intended investment: I=100
Consumption: C=50+0.8(Y-Tn), where Tn is the net tax flow
Government purchases: G=66
Government transfer payments=10
12. The following aggregate expenditure flows are given for the
small country of Hilaria. All figures are billions of Hilarious

Government purchases: G=50
13. (a)請根據下面兩個市場模型之資料,求出財貨市場與貨幣市場同時達到均衡時之所得水準與利率水準。
C = 100 + 0.75 Yd
I = 200-500 I
G = 150
T = 100
X = 200
M = 200
L (Md) = 80 + 0.2 Y - 400 i
Ms = 300
(b)請利用(a)問題之結果為起始點,現假設政府當局欲使均衡國民所得水準增加到$1400,而政府打算只採用貨幣政策,則貨幣供給必須要增加多少才能達到目標?
