Question 79

The economy's AS curve is often assumed to be relatively flat at low levels of real GDP.The underlying reasoning is that

C)at low levels of output,firms are faced with unused capacity and thus can increase output without significantly increasing their costs.
D)the price level is constant.
E)profits are normally high in this section of the AS curve,so firms are willing to expand output.

Question 80

B)at any given price level,a higher level of output will be supplied.
C)there is a decrease in aggregate supply.
D)there is a demand shock.
