问一道题:NO.PZ2016010801000053

问题如下:

All else equal, which of the following was not a factor to increase the government deficit?

选项:

A.

an increase in the excess of private saving over private investment.

B.

an increase in net export.

C.

a increase in trade deficit

解释:

B is correct.

The fiscal balance equation is given as: (G-T)=(S-I)-(X-M), An increase in government deficit (G-T) is a combination of increase in private saving over private investing (S-I) and a decrease of trade deficit or net export (X-M).

考点:Relationship between Income Approch and Expenditure Approach

解析:

财政平衡方程为:(G-T)=(S-I)-(X-M),政府赤字(G-T)的增加的同时,私人储蓄增加超过私人投资(S-I),或者贸易赤字或净出口(X-M)减少,所以AC选项不入选,B选项入选。

当G-T增大的时候, 不就意味着S-I增大或X-M减小么

那答案里面,应该是净出口(净出口一般为正数)减小, 而贸易赤字增大.

那正确答案不应该是选C才对么?

同学你好,是government deficit是减少的,政府赤字会好转。请知悉

G-T=(S-I)-(X-M),-(X-M)变大,G-T应该变大才对不是吗?

同学你好,你的思路没问题。是这样的

但B又是怎么错的呢

嗨,从没放弃的小努力你好:


同学你好,C选项的意思是进出口贸易赤字变大,是-(X-M)变大,因而(G-T)会变小,请知悉。

老师 这么理解是对的吗 trade deficit means NX < 0 (export < import) a increase in trade deficit means (NX) 负得更多了 (G-T)=(S-I)-(NX) 右边扣掉一个负得更多的 等于加上 所以左边government deficit是增加的
