关于Domestic price level

  1. CFA I
  2. Economics Analysis

NO.PZ2018062003000200

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

这道题应该是用这张图的公式。我是不是可以认为，Domestic price level就是CPI(D)？

嗨，努力学习的PZer你好：

Hello，亲爱的同学~

理解正确。国内商品价格可以看成公式里的CPI(D)。准确说，是较高的国内价格增长率。

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