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? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.174.65.202

第一題用畫的應該不好 因為是問實質GDP

所以要推乘數效果 比較Y跟P的變化大小

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

Fleming跟Mundell都假設P等於一 BP線無法解釋P的變動

其實1.2題問的東西一樣 差別在於一個是T一個是G
