帮朋友问的，经济好久不学了忘得精光。。谢谢大家


In reality, consumption and interest rates are strongly negatively correlated with each other at extremely high levels of statistical significance.  For example, using quarterly Japanese data since 1990Q1, the correlation coefficient between real consumption and the nominal three-month treasury bill rate is -.59.  Discuss how this fact should be incorporated into the simple IS-LM model which posits a simple “Keynesian” consumption function.
在现实中，消费和利率呈现统计意义上显著的负相关关系。例如，研究日本1990年第一季度以来的季度数据，发现实际消费与名义3个月短期国库券利率之间的相关系数为-0.59。讨论如何能够把这一事实体现到简单IS-LM模型中。（提示：修正简单凯恩斯消费函数）
