问题如下：

A decrease in the real exchange rate (quoted in terms of domestic currency per unit of foreign currency) is most likely to be associated with an increase in which of the following?

选项：

A.

Foreign price level.

B.

Domestic price level.

C.

Nominal exchange rate.

解释：

B is correct.

The real exchange rate (quoted in terms of domestic currency per unit of foreign currency) is given by:

Real exchange rate(d/f)=Sd/f * (Pf/Pd))

An increase in the domestic price level Pd decreases the real exchange rate because it implies an increase in the relative purchasing power of the domestic currency.

解析： Real exchange rate

Real exchange rate(d/f)=Sd/f * (Pf/Pd))

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

问题如下：

选项：

A.

Foreign price level.

B.

Domestic price level.

C.

Nominal exchange rate.

解释：

B is correct.

The real exchange rate (quoted in terms of domestic currency per unit of foreign currency) is given by:

Real exchange rate(d/f)=Sd/f * (Pf/Pd))

An increase in the domestic price level Pd decreases the real exchange rate because it implies an increase in the relative purchasing power of the domestic currency.

解析： Real exchange rate

Real exchange rate(d/f)=Sd/f * (Pf/Pd))

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

嗨，爱思考的PZer你好：



Hello，亲爱的同学。我们看这个公式：Real exchange rate(d/f)=Sd/f * (Pf/Pd))


题目问，怎样使Real exchange rate(d/f)减少：

根据以上公式：Sd/f减少，Pf减少，Pd增加，都会使Real exchange rate减少。


B选项说的是Pd增加，因此选B。

A选项说的是Pf增加，Pf增加不满足题目要求的“Real exchange rate(d/f)减少”。因此不选A。
