1.自動提款機的普及降低了人們對貨幣的需求。
根據Mundell-Fleming模型,
a.在浮動匯率制度下,會使所得水準與淨出口皆增加
b.在浮動匯率制度下,會使所得水準增加血淨出口不變
c.在浮動匯率制度下,會做淨出口增加但所得水準不變
d.在固定匯率制度下,會使所得水準與淨出口皆增加
e.在固定匯率制度下,會使所得準與淨出口皆不變

答案:a、b、c

我的想法: 降低了人們對貨幣的需求會使LM曲線左移,
會導致國際收支盈餘
就浮動來說,政府不干預外匯市場,國際收支盈餘
,此時會本幣會升值(利於進口,不利出口),淨出
口會減少吧?!IS也會左移啊??

就固定來說,因為固定制度下,匯率固定住,因此
沒有差異,所以淨出口沒有變,我這段話的分析
好像不是很嚴謹??

2.若採取固定匯率國家之貨幣被高估,則有可能發生投機攻擊

我的疑問:所謂的投機攻擊會採取怎樣的手段??


3.依據凱因斯模型:Y =C(Y-T) +I+G+NX(e,Y) , dNX/de >0 ,

δNX/δY < 0 ,δ:偏微符號。 下例何種方法不能縮減一國

貿易赤字?

a減少自發性進口 b減少自發性消費 c減少投資
d減少政府消費 e減稅

答案:e

我的想法: 因為縮減貿易赤字就等於提高淨出口意思是一樣的。
Y=C+I+G+(X-M)又等於 C+S+T, 而Y與NX呈反向關係
因為只有a選項會使Y增加,相對的就會使NX減少,
我覺得應該為a吧?!
