Ques
A student was asked to draw an aggregate demand and aggregate supply graph to illustrate the effect of an
increase in aggregate supply. The student drew the following graph:
SRAS,
The student explained the graph as follows:
"An increase in aggregate supply causes a shift from SRAS, to SRAS, Because this shift in the aggregate
supply curve results in a lower price level, consumption, investment, and net exports will increase. This change
causes the aggregate demand curve to shift to the right from AD, to AD, We know that real GDP will increase,
but we can't be sure whether the price level will rise or fall because that depends on whether the aggregate
supply curve or the aggregate demand curve has shifted farther to the right. I assume that aggregate supply
shifts out farther than aggregate demand, so I show the final price level, P3, as being lower than the initial price
level,
P.
P,
SRAS,
P3
Which of the following is a correct statement about the student's analysis?
P2
AD2
O A. The student's analysis is correct.
AD,
O B. The student is incorrect because the price level should rise when SRAS increases.
O C. The student is incorrect because the aggregate demand curve does not shift because of the price level
change.
Real GDP, Y
O D. The student is incorrect because the aggregate demand curve should decrease, not increase.
