AP Macroeconomics Unit 3 practice questions
Try 10 multiple-choice questions from Unit 3 here. Pick an answer to see why it's right or wrong, then take the timed test above for a full AP-style set.
Question 1
A major hurricane destroys significant oil refinery capacity along the Gulf Coast, causing gasoline prices to spike nationwide while unemployment rises and real GDP declines. This economic situation best illustrates which of the following concepts?
Cost-push inflation resulting from a negative short-run aggregate supply shock
Demand-pull inflation resulting from a positive aggregate demand shock
Deflation resulting from a negative short-run aggregate supply shock
Cost-push inflation resulting from a positive aggregate demand shock
Demand-pull inflation resulting from a negative aggregate demand shock
Show answer
Answer: (A)
Recognizing that supply disruptions raise production costs and reduce output identifies the core mechanism. The hurricane reduces productive capacity, shifting SRAS leftward, which simultaneously raises the price level and decreases real GDP—the defining characteristics of cost-push inflation from a negative supply shock.
Question 2
Nominal wages in an economy are fixed by contract at $25 per hour. If the price level increases from 100 to 125, what is the new real wage rate and the resulting effect on the unemployment rate as the economy moves along the short-run aggregate supply curve?
$20.00, which causes the unemployment rate to decrease
$20.00, which causes the unemployment rate to increase
$31.25, which causes the unemployment rate to decrease
$31.25, which causes the unemployment rate to increase
$25.00, which causes the unemployment rate to decrease
Show answer
Answer: (A)
Calculating the real wage ($25 / 1.25 = $20.00) reveals that labor has become relatively cheaper for firms. This decrease in real wages incentivizes firms to hire more workers to increase production, leading to a decrease in the unemployment rate.
Question 3
An economy is currently producing at a point inside its production possibilities curve. To simultaneously achieve full employment and increase future productive capacity, which combination of changes must occur?
Aggregate demand must increase to move production to the curve, and investment in capital must increase to shift the curve outward
Aggregate demand must decrease to move production to the curve, and investment in capital must increase to shift the curve outward
Aggregate demand must increase to move production to the curve, and investment in capital must decrease to shift the curve outward
Aggregate demand must decrease to move production to the curve, and investment in capital must decrease to shift the curve outward
Show answer
Answer: (A)
Synthesizing the requirements for efficiency and growth reveals the need for two distinct actions. Moving to the curve requires using idle resources (demand), while shifting the curve requires expanding capacity (investment).
Question 4
Keynesian models often assume "sticky prices" in the short run. How does this assumption limit the market's ability to resolve a surplus compared to the classical model?
Sticky prices prevent the price drops needed to clear a market surplus.
Sticky prices prevent the quantity supplied from adjusting downward to clear a market surplus.
Sticky prices prevent the quantity demanded from increasing to clear a market surplus.
Sticky prices prevent wage adjustments needed to clear a market surplus of labor.
Sticky prices prevent the quantity demanded from falling to clear a market surplus.
Show answer
Answer: (A)
Describing the limitation of a model assumption is central to the skill. If prices cannot fall (are sticky downward), the market cannot eliminate the excess supply () through the normal price adjustment mechanism.
Question 5
A sharp rise in stock market values increases household wealth. Which chain of events best describes the resulting impact on the economy?
Consumption spending rises, increasing aggregate demand and output
Consumption spending rises, but aggregate demand falls due to crowding out in the loanable funds market
Consumption spending rises, but output falls due to higher inflation reducing real purchasing power
Consumption spending rises, increasing aggregate demand but leaving output unchanged due to full employment
Consumption spending rises, but output falls because the wealth effect is offset by lower investment
Show answer
Answer: (A)
A rise in stock values makes households feel wealthier, so they increase spending even without a change in income. This wealth effect raises consumption, shifting aggregate demand and output upward.
Question 6
A technological breakthrough makes new machinery highly profitable. How will the resulting change in investment spending affect the labor market?
Labor demand will increase to produce the new capital goods
Labor demand will decrease to produce the new capital goods
Labor supply will increase to operate the new capital goods
Labor supply will decrease to operate the new capital goods
Show answer
Answer: (A)
Connecting investment to factor markets reveals that higher demand for machinery requires more workers to build it. This increases labor demand in the capital goods sector.
Question 7
Which of the following correctly compares the policy approaches typically used to address cyclical versus structural unemployment?
Cyclical requires demand-side stimulus; structural requires job retraining programs
Cyclical requires job retraining programs; structural requires demand-side stimulus
Cyclical requires expansionary monetary policy; structural requires expansionary fiscal policy
Cyclical requires reducing labor force participation; structural requires wage subsidies for displaced workers
Show answer
Answer: (A)
Matching the cause to the cure reveals that cyclical unemployment (caused by low demand) needs demand-side stimulus, while structural unemployment (caused by skills mismatches) needs supply-side interventions like training to improve worker employability.
Question 8
During an economic expansion, the actual unemployment rate falls to 4%, while the natural rate is estimated at 5%. The difference of -1% indicates which economic condition?
An inflationary gap with negative cyclical unemployment
A recessionary gap with positive cyclical unemployment
A structural shift with zero frictional unemployment
A full employment equilibrium with zero output gap
A deflationary gap with negative structural unemployment
Show answer
Answer: (A)
Calculating the difference shows the actual rate is lower than the natural rate (4% < 5%). This negative cyclical unemployment indicates the economy is overheating, producing beyond its long-run potential, which characterizes an inflationary gap.
Question 9
The current unemployment rate is 4%, which economists estimate is the natural rate. If the government tries to reduce unemployment to 0%, the likely outcome is:
Accelerating inflation as aggregate demand exceeds potential output
Sustainable long-term growth as all labor resources are utilized
A decrease in the labor force participation rate due to burnout
An increase in structural unemployment due to skills mismatches
Show answer
Answer: (A)
Interpreting the natural rate concept: 0% unemployment is impossible/undesirable because frictional and structural unemployment always exist. Pushing beyond the natural rate overheats the economy.
Question 10
If the actual unemployment rate is 8% and the natural rate of unemployment is 5%, which of the following best describes the state of the economy?
The economy is in a recessionary gap with 3% cyclical unemployment
The economy is in an inflationary gap with 3% cyclical unemployment
The economy is in a recessionary gap with 3% structural unemployment
The economy is in an inflationary gap with 3% structural unemployment
The economy is in an inflationary gap with 3% frictional unemployment
Show answer
Answer: (A)
Comparing the actual rate (8%) to the natural rate (5%) reveals positive cyclical unemployment (3%). Positive cyclical unemployment indicates the economy is producing below potential GDP (recessionary gap).
