货币供给暂时增加和永久增加的IS-LM模型分析——以DD-AA模型为对照

The analysis of temporary increase and permanent increase in money supply using IS-LM model——in comparison with DD-AA model

经济分析中常用的宏观经济模型是IS-LM模型,然而IS-LM模型对于货币供给增加的分析却没有区别暂时性增加和永久性增加;在DD-AA模型区别分析货币供给暂时性增加和永久性增加的基础上,我们增加了IS-LM模型对于货币供给暂时性增加和永久性增加的分析,并且分析结果显示这种区别是重要的和不可忽略的。

The most-often-used macro-economic model in economic analyses is IS-LM model, however this model do not show the difference between temporary increase and permanent increase in money supply when used to analyze economic outcomes made by increasing in money supply; we make this kind of analysis using IS＇LM model based on the analysis of this difference by using another kind of macro-economic model--DD-AA model, and this analysis shows that this difference is important and not negligible.
