问题如下:
Which of the following best describes a fundamental assumption when monetary policy is used to influence the economy?
选项:
A.
Financial markets are efficient.
B.
Money is not neutral in the short run.
C.
Official rates do not affect exchange rates.
解释:
B is correct.
If money were neutral in the short run, monetary policy would not be effective in influencing the economy.
考点: Money neutrality
解析:如果货币中性在短期发生,那么在短期货币供给不能影响经济中的真实变量,那么货币政策就是无效的,所以B选项说法正确。
A选项没有B选项好,如果金融市场不有效,货币政策多多少少也会有点作用,但是一旦货币中性在短期发生,那么货币政策就一点效果也没有。
C选项是一个打酱油的选项,错误。
请问市场中性不是对短期有影响,长期没有影响吗?为什么选B
