※ 引述《afoh (afoh)》之銘言：
: 以下有幾題不太懂請各位幫忙解答吧
: (1)Suppose we have an initial equilibrium with curves IS(0) and LM(0)
: [括號中的0代表初始的那條線]
: The price level then rise.At every point on LM(0);there is now an escess
: ______ real balances,which is eliminated at each income level by a _____
: in the interest rate, meaning that the new LM curve is ______ LM(0)
: (A)demand for,fall,above
: (B)demand for,fall,below
: (C)demand for,rise,above
: (D)supply of,rise,above
: (E)supply of,fall,below
: Ans:C 但是LM的超額供給不是在原LM線的上方嗎 所以我疑惑了
P上升-->M/P<L(r，Y)==>(Ls<Ld)
由於P對於ISLM為外生變數，P上升使LM上(左)移
: (2)A tax decrease shifts the IS curve,causing a _____domestic interest rate,
: leading to ____ of the dollar.
: (A)higher,depreciation
: (B)higher,appreciation
: (C)lower,depreciation
: (D)lower,appreciation
: Ans:C 但是稅降低不是會使IS右移嗎,然後r不就會上升,另外不太懂跟升貶值有什麼關係
減稅使IS右移，使國內利率下降，本國相對外國利率低，資金流出，本國貨幣貶值。
: (3)Given the following IS-LM model:
: C=80+0.625Y , I=160-100i ; L=60+0.25Y-200i , M=190
: What are the equilibrium values of Y and I?
: (A)600;10.5%
: (B)610;11.25%
: (C)620;12.5%
: (D)630:13.25%
: Ans:B 但是我算不出來耶
兩條式子聯立可求y與i，i代入I即可求解。
: (4)Which of folling starements is correct?
: (A The flatter IS curve,the more effective the monetary policy
: (B)The sreeper IS curve,the more effective the fiscal policy
: (C)A fiscal expansion will cause smaller crowding out effect when the
: LM curve is flatter
: (D)A fiscal expansion will cause smaller crowding out effext when the LM curve
: steeper
: Ans:A 但是我覺得A跟B都對耶
假如LM斜率為正，兩者皆對
但LM斜率若為零，A則對，B則錯
無限大，政策影響皆同。(無意義)
: (5)Deregulation and innovation in financial markets usually make
金融市場解除管制和金融創新通常會使…
: (A)The IS curve flatter
: (B)the LM curve steeper
: (C)both IS and LM curve flatter
: (D)no influence on IS curve
: Ans;C 翻譯完了但我還是看不懂他想問什麼
利率的貨幣需求彈性會變大吧(?!)，取絕對值的話~~
不確定~~
有錯請指正
