[問題] 98交大科管經濟

[frplz (frplz)]

請問大家，申論題這三題大家是怎麼分析的？

聽說要用BP線，但是我不知道要怎麼在封閉和開放經濟中比較

因此想請問大家，謝謝！！

1. Suppose that the government increases taxes without also increasing
spending.In the short run,how will this action affect
real GDP and the price level in a closed economy ?
How will the effect of this action differ in an open economy?

2. Fiacal policy has a greater impact in a closed economy than it
does in an open economy?

3.Ceteis paribus,falling demand by foreign portfolio managers
for US stocks and bonds will cause a depreciation
in the dollar and rising US price level?

推 ford903:第一題用畫的應該不好 因為是問實質GDP
→ ford903:所以要推乘數效果 比較Y跟P的變化大小
→ ford903:用畫得比較沒辦法清楚解釋
→ ford903:然後開放後IS跟LM的內生變數會不一樣 所以乘數效果變小
→ ford903:不過還是要用全微分微給老師看吧  請高手指正
推 ford903:Fleming跟Mundell都假設P等於一 BP線無法解釋P的變動
→ ford903:第三題可以用BP線的圖  但是二三還是要推乘數
推 ford903:其實1.2題問的東西一樣  差別在於一個是T一個是G
