LEVEL 1 ECONOMICS的问题 影响, previous, interest, decrease, employment

胡老师，你好

我有两个关于LEVEL 1 ECONOMICS的问题想请教您。

在Schweser Study Note Book 2(Economics)P139上说“Recall from our previous discuss that when a central bank unexpectedly decreases the rate of money supply growth to reduce inflation, that the initial effect is to decrease aggregate supply as real wages fall and to reduce both GDP and employment”。可在p130上讲解Money, Interest, Real GDP and the Price Level解释时却说当money supple 降低时，interest rate增加，首先受影响的是Aggregated Demand应decrease,其后再是Aggregated Supply受影响，而非Aggregated Supply先受影响。

还有，“decrease the rate of money supply growth”和“decrease the money supply”是不是一回事？就是垂直的money supply向左移？

多谢回复

这个问题似乎难以回答，货币供给到底先影响需求，还是供给没有明确的答案，一般认为，对金融资产的影响迅速，对实体经济发生效果是有时滞的。

还有，“decrease the rate of money supply growth”和“decrease the money supply”是不是一回事？就是垂直的money supply向左移？
不是一个事情，decrease the rate of money supply growth是指的货币供给增长的速度下降，比如原来是5%,现在是３％。decrease the money supply是货币供给总量的减少。
