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…
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
суcle
economists call this change in real
terminology,
what
would
GDP?
2. Suppose that the table below shows an economy's relationship
between real output and the inputs needed to produce that output:

a. What is productivity in this economy?
b. What is the per-unit cost of production if the price of each input
unit is $2?
c. Assume that the input price increases from $2 to $3 with no
accompanying change in productivity. What is the new per-unit cost
of production? In what direction would the $1 increase in input price
push the economy's aggregate supply curve? What effect would this
shift of aggregate supply have on the price level and the level of real
output?
d. Suppose that the increase in input price does not occur but,
instead, that productivity increases by 100 percent. What would be
the new per-unit cost of production? What effect would this change
in per-unit production cost have on the economy's aggregate supply
curve? What effect would this shift of aggregate supply have on the
price…
