[考試] IS-LM模型
來源: 淡江期中考題
科目:總經
問題:
１.The LM curve is steeper the ______ the interest sensitivity of money demand
and the ______ the effect of income on money demand.
A) smaller; greater
B) smaller; smaller
C) greater; greater
D) greater; smaller
2.Other things equal, a given change in government spending has a larger
effect on demand the:
A) steeper the IS curve.
B) smaller the interest sensitivity of money demand.
C) flatter the IS curve.
D) larger the interest sensitivity of expenditure demand.
我的想法:
1.LM越陡 => Δr/ΔY 越大
假設ΔY固定， Δr越大
即LM線越陡，對r的敏感度越大；
反之，則為對收入之敏感度 (越小)
給的答案是A，但我覺得答案應該是D
2.看到G變動，所以想到的會是IS，
先把B.D刪掉，接著考慮A.C
這題我的想法跟第一題類似，也是覺得越平坦，
同樣的Δr下，ΔY會越大
答案給的是A，可是我覺得答案應該是C
以上，兩題感覺概念應該很類似(?)
不知道是不是我誤解了題目的意思，還是答案錯了...
麻煩各位幫忙了，感謝！
