问一道题：NO.PZ2018062003000200

  1. CFA I
  2. Economics Analysis

问题如下：

When the real exchange rate( assuming domestic currency is price currency and foreign currency is base currency) increased, which of the followings is most likely to be associated with an decrease?

选项：

A.

Nominal exchange rate.

B.

Domestic price level.

C.

Foreign price level.

解释：

B is correct.

The formula of real exchange rate is :

Real exchange rate (d/f) =Sd/f×(Pf/Pd){}_{(d/f)\text{ }}=S_d/f\times(P_f/P_d)

An decrease in the domestic price level increases the real exchange rate because it implies an decrease in the purchasing power of the domestic currency compared to foreign currency.

考点： exchange rate

解析： Real exchange rate (d/f) =Sd/f×(Pf/Pd){}_{(d/f)\text{ }}=S_d/f\times(P_f/P_d)

根据上述公式，较高的Nominal exchange rate，较高的Foreign price level，以及较低的Domestic price level会产生较高的Real exchange rate

外币是基础货币说明买卖外币。本币/外币 这个值增加说明本币贬值外币升值，所以要用更多的本币才能在本国买同样的东西，所以本国的price level不应该是上升么？

同学你好，本币贬值肯定会对本国经济有影响，但一般是从国际贸易的角度，也就是BOP角度分析对本国经济的影响。

嗨，爱思考的PZer你好：


同学你好，本币贬值，并不代表“用更多的本币才能在本国买同样的东西”，这个逻辑是不成立的。

那是说，本币贬值与否只是针对国际间来说，通胀才是对于一国国内货币来说。本币贬值说明对国外向国内的投资更有吸引力，那本币贬值对于国内的影响是什么呢？还是本币贬值对于国内消费完全没影响?

NO.PZ2018062003000200 所以reexchange rate是默认 price/base吗 还是看具体题目要求？
