问题如下:

The mechanism about which Thibodeaux is most confident as an explanation for the long-run equilibrium value of exchange rates is best described as the:

选项:

A.debt sustainability channel. B.flow supply/demand channel. C.portfolio balance channel.

解释:

Solution

A is correct. Thibodeaux prefers the debt sustainability channel as a means to assess the long-run equilibrium value of exchange rates. According to this mechanism, there should be some upper limit on the ability of countries to run persistently large current account deficits. If a country runs a large and persistent current account deficit over time, eventually it will experience an untenable rise in debt owed to foreign investors. If such investors believe that the deficit country’s external debt is rising to unsustainable levels, they are likely to reason that a major depreciation of the deficit country’s currency will be required at some point to ensure that the current account deficit narrows significantly and that the external debt stabilizes at a level deemed sustainable.

B is incorrect. The flow supply/demand channel mechanism focuses on the fact that purchases and sales of internationally traded goods and services require the exchange of domestic and foreign currencies in order to arrange payment for those goods and services. Such shifts in currency demand should exert upward pressure on the value of the surplus nation’s currency and downward pressure on the value of the deficit nation’s currency.

C is incorrect. The portfolio balance channel assumes that current account imbalances shift financial wealth from deficit nations to surplus nations. Countries with trade deficits will finance their trade with increased borrowing. This behavior may lead to shifts in global asset preferences, which in turn could influence the path of exchange rates.

嗨,爱思考的PZer你好:


这道题问的什么?答案又分别什么意思呢?

这道题不适用最新2023版考纲了。

关于这部分知识点,我们就记忆强化讲义中这些表格中的名词就可以了。

当然同学也可以拓展一下自己的知识点。



A选项的debt sustainability channel也就是表格中的external sustainability approach。新的考纲把名词改了,但是意思差不多。

B选项的flow supply/demand channel,是指贸易顺差国的货币会升值。贸易逆差国的货币会贬值。即国际贸易货物和服务的购买和销售需要本国货币和外币的兑换,以便安排这些货物和服务付款。货币需求的这种变化会对盈余国货币的价值产生上行压力,对赤字国货币的价格产生下行压力。

C选项的portfolio balance channel,是指投资组合平衡渠道假设经常账户失衡将金融财富从赤字国家转移到盈余国家。贸易逆差国家将通过增加借款为其贸易提供资金。这种行为可能导致全球资产偏好的变化,进而影响汇率路径。这个理论会挪到三级中学习。
