问题如下:
Money neutrality believes that a 10% decrease in money supply will
选项:
A.decrease the price level by 10%.
B.have no effects on price level.
C.decrease the production quantity by 10%
解释:
A is correct. Money neutrality refers to that the real variables, such as real GDP, will not be affected by money supply. Therefore, a 10% decrease in money supply will decrease the price level by 10%.
考点:货币中性
解析:货币中性是指不受货币供应量影响的真实变量,如实际GDP。因此,货币供应量减少10%,价格水平就会下降10%。
如果货币中性是MS不影响实际产出,只影响通胀,从而影响价格的话,原等式:nominal rate=real rate+E(I),Rnom是要随着E(I)的上涨而上涨的,但是如何量化成MS变动10%,价格也变动10%呢,而Rnom是money的价格,那么到底MS→E(I)→Price这个链条上是还有什么公式课堂中没介绍吗?
