【求助】帮忙解释下经济增长与货币供给的关系。。谢谢大家啦><

我想知道要怎么从理论上解释经济增长带来了货币供应量的增加，这个逻辑过程是什么呢？能解释的越详细越好~><还有记得好像有一个理论是说经济增长百分之多少，通货膨胀率就增加百分之多少@.@

谢谢大家啦~~

供你参考  第二种解释应该能解释你的问题了  （摘自wiki）
lucas模型是和friedman一样支持pi 改变y (or employment)  intuition有些许不同

To Milton Friedman there is a short-term correlation between inflation shocks and employment. When an inflationary surprise occurs, workers are fooled into accepting lower pay because they do not see the fall in real wages right away. Firms hire them because they see the inflation as allowing higher profits for given nominal wages. This is a movement along the Phillips curve as with change A. Eventually, workers discover that real wages have fallen, so they push for higher money wages. This causes the Phillips curve to shift upward and to the right, as with B.
Some economists[who?] reject this theory because it implies that workers suffer from money illusion. However, one of the characteristics of a modern industrial economy is that workers do not encounter their employers in an atomized and perfect market. They operate in a complex combination of imperfect markets, monopolies, monopsonies, labor unions, and other institutions. In many cases, they may lack the bargaining power to act on their expectations, no matter how rational they are, or their perceptions, no matter how free of money illusion they are. It is not that high inflation causes low unemployment (as in Milton Friedman's theory) as much as vice-versa: Low unemployment raises worker bargaining power, allowing them to successfully push for higher nominal wages. To protect profits, employers raise prices.

不知道你是不是说这个 （我不大懂宏观）

lucas supply function
y=yn+alpha*(pi-pi^e)+e

deviation of y  和 inflation和预期inflation的差值  有这么个关系
简单的模型可以从rbc模型配上wage的stickness推出来

原始模型见Lucas, R.E., Jr. (1972), “Expectations and the Neutrality of Money,” Journal of Economic Theory, 4, 103-124.
lucas 原始模型的intuition 是由于信息不对称造成的

一个cheap的解释 用wage 的stickness是说 预期wage 和实际wage的差异是被通胀率与预期通胀率的差值决定的  而这个预期与实际的wage的差异将决定经济output的差异

啊~~遇上高人了~~谢谢你的回复~但是。。可以解释的通俗一些么||||用经济意义的解释方式不用数理模型><~~
（就像因为经济增长增加了对货币的需求，然后货币需求又影响了什么。。最后说到对货币供给的影响）
再次感谢~~

通货膨胀率=（名义GDP-实际GDP）/实际GDP

谢谢你的回复~~但这个主要是从物价水平P的角度考虑，我想知道就Y的变化是如何影响到货币供应量M的变化，然后因为M的增加而增加了流动性~主要是讲从Y到M的这个中间过程的经济意义~

那是菲利普斯提出的一个理论，现在的通货膨胀率-过去的通货膨胀率=-弹性系数（实际就业率-充分就业率）

lucas模型是用来解释为什么inflation 能够调整output （supply side)

为什么output 能够调整inflation 这个我没记起来会这样  也没记起来哪个模型能够解释这个   唯一有点关系的我记得起来的是new Keynesian 的forward looking inflation  是关于price rigidity  然后造成 goods rigidity 的  

不好意思
宏观很多东西忘记了  inflation 要调整的话 从需求看  必须要需求的大与供给的output  这样inflaton才会调整  可是通常都认为是supply side调整了inflation

不好意思我今天查了下 摘自wiki  Demand-pull inflation is caused by increases in aggregate demand due to increased private and government spending, etc. Demand inflation is constructive to a faster rate of economic growth since the excess demand and favourable market conditions will stimulate investment and expansion. Demand-pull theory states that the rate of inflation accelerates whenever aggregate demand is increased beyond the ability of the economy to produce (its potential output). Hence, any factor that increases aggregate demand can cause inflation.[44] However, in the long run, aggregate demand can be held above productive capacity only by increasing the quantity of moneyin circulation faster than the real growth rate of the economy. Another (although much less common) cause can be a rapid decline in the demand for money, as happened in Europe during the Black Death, or in the Japanese occupied territories just before the defeat of Japan in 1945.就是这个观点

谢谢你的回复~菲利普斯曲线好像主要讨论的是失业率和通货膨胀率的关系~我比较想知道经济增长和货币供应，经济增长和通货膨胀之间的关系~><

不过我刚才查了一下，结合奥肯定律（经济增长和失业率）和菲利普斯曲线可能可以解释之间的关系><~
谢谢你提供的思路哈~~因为只能设一个最佳回复><~所以可以麻烦你上传一个20币的附件么~我会购买滴~~

谢谢你~虽然还不是我很想要的答案><~但是我已经有一些方向了~~
那我把你设为最佳回复了~~
