GDP是怎么影响the demand for money的?

首先给你说人们要钱的3个动机(motive)：
1.Transaction motive
People hold money in order to undertake transactions
2.Precautionary motive
Money is held as a precaution against unexpected events that require unplanned purchases to be made.
3.Speculative motive
People hold money in order to avoid losses from holding stocks or bonds that are expected to fall in value.
然后让你知道GDP分为 NGDP（Nominal GDP) 和 RGDP（real GDP)
NGDP 可以说就是个数据而已
RGDP 才是管事的
影响demand of money的有3个因素
一个是Price level,一个是RGDP,还有一个是interest rate
假设Price level和interest不变,那RGDP与demand of money成正相关
然后再补充个与GDP相关的概念
GDP=output,对吧
按理来算,output=expenditure
所以说,当GDP增加了,expenditure也会响应增加,所以说,人们就会想要更多的钱了
不知道我解释的够不够清楚
