问题如下:
A current account deficit is least likely caused by which of the following items ?
选项:
A.High private investment.
B.High private savings.
C.Low taxes.
解释:
B is correct
The reasons lead to a current account deficit include low private saving, high private investment, a government deficit, or a combination of the three. Above all the choices, only high private savings is least likely to contribute toward a current account deficit.
考点:Trade Balance.
解析:X-M=(S-I)-(G-T)
通过上述公式可以得知,较高的 private investment,较低的 private savings 以及较低的 taxes都会引起X-M的降低( Crrent account deficit )。
这题 为什么要用这个公式,而不是BOP中的current account?
