问题如下：

QuestionSuppose the nominal spot exchange rate (CAD/JPY) rises by 6.2%, the Japan price level drops by 3.8%, and the Canadian price level escalates by 1.8%. The alteration in the real exchange rate (%) is most nearly:

选项：

A.0.36%.

B.–0.66%.

C.1.8%.

解释：

Solution

The formula for the real exchange rate is: Real exchange rate = Nominal spot exchange rate × (CPI of the foreign nation/CPI of the home nation)

Change in the real exchange rate = [(1 + Change in exchange rate) × (1 + Change in price level in foreign nation)]/(1 + Change in price level in home nation) – 1

= [(1 + 6.2%) × (1 - 3.8%)]/(1 + 1.8%) - 1 = 0.36%

The Foreign Exchange Market and Capital Flows

• describe the foreign exchange market, including its functions and participants, distinguish between nominal and real exchange rates, and calculate and interpret the percentage change in a currency relative to another currency

实际汇率的计算公式为:实际汇率=名义即期汇率×(外国CPI /本国CPI)
实际汇率变化量=[(1 +汇率变化量)×(1 +国外价格水平变化量)]/(1 +本国价格水平变化量)- 1
=[(1 + 6.2%)×(1 - 3.8%)/ (1 + 1.8%)- 1 = 0.36%

嗨，爱思考的PZer你好：


根据书本原文：

The formula for the real exchange rate is: Real exchange rate = Nominal spot exchange rate × (CPI of the foreign nation/CPI of the home nation)

可以推导出：

Change in the real exchange rate = [(1 + Change in exchange rate) × (1 + Change in price level in foreign nation)]/(1 + Change in price level in home nation) – 1


由此可见，本题给的公式，这是一个精确公式。

而书本例题给的方法，是近似公式，符号是≈，不是=


同学尽量使用精确公式来计算。

因为有时候，精确式子和近似式子，结果差距会相对大一些。

虽然现在很辛苦，但努力过的感觉真的很好，加油！
