IS-LM-BP图形分析的数学推导

Mathematical Demonstration on IS-LM-BP Model

鉴于教科书中对于IS-LM-BP模型的图形分析主要依靠叙述变量之间的逻辑关系,而不是直接应用模型本身所假设的数学性质,容易造成分析上的混乱,分析了根据模型自身所具有的数学性质,来判断曲线的移动和曲线两侧的失衡状态,这既是比较静态分析的直接应用,也可以应用于其他的类似图形分析之中.

This paper is concerned with how to do with IS -LM -BP model using mathematic analysis instead of talking a lot of logical relation between variables, which is easy to confuse the researcher. Based on the mathematical premise of IS - LM - BP model, the direction of curves movement and the unbalanced status beside the curves can be accessed rapidly. This approach is comparative-static analysis, which can also be used to analyze other similar figures.
