a. Use the data above 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 aggregate demand curve as AD1. What is the new equilibrium
price level and level of real output?
4. Suppose that the following table shows an economy's relationship between real output and the inputs needed to produce that output: LO7.3
Input Quantity
Real GDP
150.0
$400
112.5
300
75.0

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
level and the level of real output?
