问题如下:
When there is a decrease of price level on the aggregate demand curve,
选项:
A.the interest rate will the decline.
B.the interest rate will increase.
C.the interest rate will not change.
解释:
A is correct.
When the price level is decreasing, LM curve will shift to right and intersect with IS curve at a lower interest rate.
考点:AD曲线
解析:当价格水平下降时,表明真实货币供给减少,LM曲线发生向右平移。与IS曲线交于更低的位置,这个位置对应的利率水平就更小,所以A选项正确。
老师, P上升,MS/P 下降 , R就会上升,从而投资下降,Y下降。
AD曲线的推导过程 好像跟它矛盾了。
