对本题A选项的疑问

NO.PZ2016010801000119

问题如下:

In order to reduce trade deficit in a country, a feasible way is

选项:

A.

Increasing its capital account surplus.

B.

Decreasing expenditures relative to income.

C.

Decreasing domestic saving relative to domestic investment.

解释:

B is correct.

In a country, decreasing a capital account surplus will improve a country trade deficit, which means domestic savings increase relative to domestic investment. Domestic savings increase means decreasing expenditures relative to income. A large capital account surplus (an increase in net foreign borrowing) and a greater trade deficit is consistent with decreasing domestic saving relative to domestic investment.

考点:The Trade Balance

解释:在一个国家,减少资本账户盈余将改善该国的贸易赤字,这意味着国内储蓄相对于国内投资有所增加。所以A错误,B正确。

而国内储蓄的增加意味着支出相对于收入的减少。所以C错误。

巨额资本账户盈余(净外国借款的增加)和更大的贸易逆差,与国内储蓄相对于国内投资的减少是一致的。

改善经常账户赤字,即增加(X-M),按照课堂讲义讲解,如有赤字,即X-M<0, 则需要海外资本流入,如以下幻灯片所述:


如此,外资流入,不就带来资本账户金额增加吗?怎么又是减少?我看到之前老师的答疑为(X-M)的增加即(M-X)的减少,其中(M-X)即为资本账户,那幻灯片中capital infiow又如何理解?

嗨,从没放弃的小努力你好:


如此,外资流入,不就带来资本账户金额增加吗?

外资通过资本账户流入,会带来资本账户金额增加。同学这个理解没问题。


怎么又是减少?

但外资通过经常账户流入,会带来资本账户余额减少。因此是减少。

所以要看外资从哪个账户流入。


我看到之前老师的答疑为(X-M)的增加即(M-X)的减少,其中(M-X)即为资本账户

X-M增加,就是M-X减少,这是一个数学关系。

X-M是经常账户,M-X是资本账户。

之前老师的答疑是完全正确的。


那幻灯片中capital infiow又如何理解?

我们PPT讲义这里的capital infiow,是指外资通过资本账户流入,资本账户增加。

资本账户增加,就是M-X增加。就是X-M减少,就是贸易赤字。

PPT这里的capital infiow,完全没有问题啊,与上面几个问题的答疑,均保持一致。
