问题如下:
A client has asked you to explain the differences between potential GDP and real GDP:
选项:
A.
Growth in potential GDP measures how rapidly the total economy is expanding.
B.
If real GDP is below potential GDP, the aggregate price level has downward pressure.
C.
If real GDP is below potential GDP, the aggregate price level tends to rise.
解释:
B is correct.
Growth in real GDP measures how rapidly the total economy is expanding. If real GDP is below potential GDP, the aggregate price level has downward pressure. If real GDP is above potential GDP, the aggregate price level has upward pressure.
考点:potential GDP
解析:是真实GDP而非potential GDP 能够准确衡量一国GDP的增长情况,所以A选项不入选。
如果当前真实GDP小于potential GDP ,表明该国当前经济不景气,物价就可能面临下行压力,所以B选项正确,而C选项错误。
之前做题时遇到说AD,AS曲线的横轴代表real GDP,根据AS曲线的超短期,短期,长期三段,长期那里对应的才是potential GDP,那么real GDP小于potential GDP就意味着是AS曲线的前两段,即先不变再上升。麻烦老师看看这个逻辑到底哪里有问题呢?
