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…

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…

Assume there is a GDP gap of 1 trillion yen and the marginal propensity to consume (MPC) is 0.60. What advice should the head of the economic council give the Prime Minister?
