问一道题: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

问题1:这里的公式是哪里来的?在351页并未找到?

问题2:这里为什么不用公式

real change rate=D/CPI /F/ CPI D是price currency F是base currency

我答复已经写了公式是在P338,为什么非要执着于P351有没有公式呢?公式在P338!

•FX real(d/f) = FX nominal (d/f) *CPIf/CPId

该公式中D/F是报价形式,它具体代表的是一个数字。要写在一起的。你下的公式里D和F分开了,没有你写的公式。

嗨,爱思考的PZer你好:


就是运用 P338公式。

同学你写的斜杠太多,应该中间有括号包裹吧,你这么写真的不太看得明白。

虽然现在很辛苦,但努力过的感觉真的很好,加油!

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