LEVEL 1 ECONOMICS的问题 interest, decrease, previous, 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(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

胡老师

decrease the rate of money supply growth”和“decrease the money supply这两个不是一回事情，一个是降低增长的速度，一个是降低绝对量的供给。

一般认为是需求先受影响，但是按照理性预期，应该两者的实际变量都不受影响。
