根据【1/（1-2%） -1】/1可以得出加元升值了多少，那为什么说Inflation in Canada就比美国的少这么多呢？

  1. CFA I
  2. Economics Analysis

NO.PZ2016010801000105

问题如下：

Last year, the nominal exchange rate for CAD/USD was 1.40. This year, the real exchange rate has decreased by 2%. Which of the following statement is most likely correct?

选项：

A.

One US dollar can exchange for more than 1.4 Canada dollars.

B.

There is a decrease of 2% in purchasing power of USD relative to CAD.

C.

Inflation in Canada is about 2% lower than that in USA.

解释：

B is correct. The real exchange rate is to assess changes in the relative purchasing power of one currency compared with another. The 2% decrease in real exchange rate indicates the 2% depreciation of USD compared to CAD.

考点：实际汇率

解析：实际汇率是用来评估一种货币相对于另一种货币的相对购买力的变化。实际汇率下降2%表明美元对加元贬值2%。所以B选项正确。

此时1单位美元换汇的加拿大的数目就少于1.4单位，A选项不正确。

C的说法不一定，所以也不入选。

嗨，爱思考的PZer你好：


Hello，亲爱的同学~

外汇里面有一个数学现象，升值幅度和贬值幅度不相等。

比如本题，对于 CAD/USD ，贬值了2%，也就是作为base currency的美元贬值2%。

那么加元升值幅度，它不是2%，是其他的一个数字。

这个要特别注意的哈，两者不等。
