问题如下:
If aggregate supply and aggregate demand increase at the same time, which of the following is most likely to happen?
选项:
A.lower real GDP.
B.lower unemployment.
C.lower aggregate price level.
解释:
B is correct.
If aggregate supply and aggregate demand both increase, it will result in higher real GDP and lower unemployment, the aggregate price level will be indeterminate.
考点:总供给和总需求
解析:总供给和总需求同时增加,将会产生更高的真实GDP,这会带动就业的上升,所以A选项错误,B选项正确。
总供给和总需求同时增加,物价水平难以确定,所以C选项不入选。
为啥real GDP增加会增加就业率呢?C为什么不对?是因为没说长期还是短期所以不能确定么?因为长期来看依旧均衡但是物价上涨
