关于aggregate demand or aggregate supply curves的题...O(∩_∩)O谢谢啦...
5. Describe each of the following outcomes in terms of shifts in aggregate demand or aggregate supply curves.
(a) A recession deepens while the rate of inflation increases
(b) The price level rises sharply while real output and employment increase
答案
A) 应该是aggregate supply curve 左移,经济衰退了,AD或者AS必然左移,但是通胀提高,所以只能是AS曲线左移.
B) 应该是aggregate demand curve 右移,经济增长的同时伴随物价水平的提高,只能是AD曲线右移.
举一反三
已知函数f（x）=x，g（x）=alnx，a∈R．若曲线y=f（x）与曲线y=g（x）相交，且在交点处有相同的切线，求a的值和该切线方程．
