5. Fiscal policy, the money market, and aggregate demand
Suppose there is some hypothetical economy in which households spend $0.50 of each additional
dollar they earn and save the $0.50 they have left over. The following graph plots the economy's
initial aggregate demand curve (AD1 ).
Suppose now that the government increases its purchases by $3.5 billion.
Use the green line (triangle symbol) on the following graph to show the aggregate demand curve (
AD2) after the multiplier effect takes place.
Hint: Be sure the new aggregate demand curve (AD2 ) is parallel to AD₁. You can see the slope of
AD1 by selecting it on the following graph.
