a. Use these sets of data to graph the aggregate demand and
aggregate supply curves. What is the equilibrium price level and the
equilibrium level of real output in this hypothetical economy? Is the
equilibrium real output also necessarily the full-employment real
output?
b. If the price level in this economy is 150, will quantity demanded
equal, exceed, or fall short of quantity supplied? By what amount? If
the price level is 250, will quantity demanded equal, exceed, or fall
short of quantity supplied? By what amount?
c. Suppose that buyers desire to purchase $200 billion of extra real
output at each price level. Sketch in the new…
: Which of the following statements is true if there is an increase in aggregate demand while the economy is
in equilibrium on a positively sloping short-run aggregate supply curve?

O a) Prices rise, national income does not change
B) Prices decrease, national income does not change
O C) Prices go up and national income goes down.
O D) Prices decrease and national income decreases.
O TO) Prices rise, national income rises
5. Refer to the data in the table that
accompanies problem 2. Suppose that
the present equilibrium price level and
level of real GDP are 100 and $225, and
that data set B represents the relevant
aggregate supply schedule for the
economy. LO12.6
a. What must be the current amount of
real output demanded at the 100 price
level?
b. If the amount of output demanded
declined by $25 at the 100 price level
shown in B, what would be the new
equilibrium real GDP? In business

economists call this change in real
terminology,
