标题[问题] 98交大科管经济
时间Wed Mar 18 22:54:59 2009
请问大家，申论题这三题大家是怎麽分析的？
听说要用BP线，但是我不知道要怎麽在封闭和开放经济中比较
因此想请问大家，谢谢！！
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?

1F：推 ford903:第一题用画的应该不好 因为是问实质GDP 03/21 22:47
2F：→ ford903:所以要推乘数效果 比较Y跟P的变化大小 03/21 22:47
3F：→ ford903:用画得比较没办法清楚解释 03/21 22:48
4F：→ ford903:然後开放後IS跟LM的内生变数会不一样 所以乘数效果变小 03/21 22:49
5F：→ ford903:不过还是要用全微分微给老师看吧 请高手指正 03/21 22:50
6F：推 ford903:Fleming跟Mundell都假设P等於一 BP线无法解释P的变动 03/21 22:54
7F：→ ford903:第三题可以用BP线的图 但是二三还是要推乘数 03/21 22:55
8F：推 ford903:其实1.2题问的东西一样 差别在於一个是T一个是G 03/21 22:59
