C为什么不对

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。

老师,这题不是问(X-M)为什么变小吗,那么s如果减少,那么(s-i)不是就减少了,那么(x-m)也就减少了呀,

嗨,努力学习的PZer你好:


老师,这题不是问(X-M)为什么变小吗,那么s如果减少,那么(s-i)不是就减少了,那么(x-m)也就减少了呀,


同学对知识点的理解是非常到位的,但是读错了题目。

reduce trade deficit 是指减少贸易逆差,减少贸易逆差 = X - M变大。而不是变小。

X - M = S -I + T -G ,减少S-I,减少X -M。但是本题要求是加大X - M。因此C不对。
