2.(15%) 若幸福國的一般物價水準不變，其凱恩斯總體經濟模型(the Keynesian
Macroeconomic Model)如下:
民間消費函數 C = 2000 + 0.5Yd
民間毛投資 I = 1000
政府消費支出 G = 800
出口 X = 1400
進口函數 IM = 400 + 0.2Y
所得稅函數 T = 100 + 0.2Y(所得稅稅率T = 0.2)
式中Y是實質GDP，Yd是可支配所得。試求：
(1) 政府消費及投資支出函數 ΔY/ΔG。
(2) 若幸福國的充分就業GDP水準 Yf = 6300，則民間投資I需增加或減少至若干才能
達到充分就業水準?

將增加或減少至若干?
3.(20%) Using aggregate supply and aggregate demand curves(the SAS/LAS/AD
model) to illustrate, describe the effects of the following events on the
price level and on equilibrium GDP in the long run assuming that input
prices fully adjust to output prices after some lag:

(2) A decrease in government spending and in the money supply with GDP
above potential GDP occurs.
