Stagflation and Supply Shocks

Active learning works for stagflation and supply shocks because the topic demands students confront counterintuitive economic relationships. When students analyze real crises like the 1973 oil shock, they move beyond abstract graphs to see how supply constraints break traditional policy tools, making the content both memorable and meaningful.

Case Study Analysis: The 1973 Oil Crisis

Groups receive a packet of primary sources including newspaper headlines, economic data, and Congressional testimony from 1973-1975. They use aggregate supply and demand diagrams to illustrate what happened and present their analysis to the class, explaining the dilemma facing policymakers at each stage.

Explain the phenomenon of stagflation and its causes.

Facilitation Tip

During the Case Study Analysis, circulate and press students to connect each piece of evidence to either the leftward shift of the aggregate supply curve or the resulting stagflation outcomes.

What to look for

Pose the following question to small groups: 'Imagine you are advising the President during a stagflationary period. What are the two most difficult trade-offs you must present regarding policy choices, and why?' Have groups share their top trade-off with the class.

Structured Controversy: Fighting Stagflation

Half the class argues for tight monetary policy to combat inflation first, while the other half argues for stimulus to reduce unemployment. After presenting arguments, groups switch sides, then the class debriefs on why no policy perfectly resolves stagflation.

Analyze how supply shocks (e.g., oil crises) lead to stagflation.

Facilitation Tip

For the Structured Controversy, assign roles clearly and remind students to reference the supply chain diagrams when debating policy choices.

What to look for

Present students with a brief scenario describing an economy with rising prices and falling output. Ask them to identify whether this scenario represents demand-pull inflation or cost-push inflation and to explain their reasoning in one to two sentences.

Think-Pair-Share: Supply Shock Scenarios

Students read brief descriptions of modern supply shocks such as semiconductor shortages and pandemic-era shipping disruptions. They diagram the aggregate supply shift individually, compare with a partner, and discuss whether current conditions resemble the 1970s stagflation environment.

Critique the challenges policymakers face when dealing with stagflation.

Facilitation Tip

In the Think-Pair-Share, limit the pairing phase to two minutes so the whole-class discussion stays focused on comparing scenarios.

What to look for

On an index card, ask students to define stagflation in their own words and provide one specific historical example of a supply shock that contributed to it.

A few notes on teaching this unit

Teachers approach stagflation by first reinforcing students’ understanding of the Phillips Curve before disrupting it. Use the historical 1970s oil crises to show how supply-side constraints create a different kind of problem. Avoid rushing to solutions; emphasize the cognitive dissonance students feel when standard Keynesian tools fail. Research suggests that making students confront this failure directly builds stronger conceptual frameworks than lecturing about it.

Successful learning looks like students confidently distinguishing supply shocks from demand shocks, explaining why stagflation contradicts the Phillips Curve, and justifying policy trade-offs with evidence from historical cases. You’ll know they’ve got it when they can critique solutions and argue from both supply and demand perspectives.

Watch Out for These Misconceptions

• During Case Study Analysis: Students may treat the 1973 oil crisis as just another inflation story. Watch for students who skip connecting OPEC’s actions to the leftward shift in aggregate supply and resulting drops in output and employment.

  During Case Study Analysis, pause the activity after they review the oil embargo details and ask: 'How does the supply reduction show up on the aggregate supply curve? What happens to real GDP and the price level?' Require them to annotate the graph with the shift and label the stagflation outcomes.

• During Structured Controversy: Students may assume expansionary fiscal policy can solve stagflation as it solves a recession. Watch for teams that propose stimulus without addressing the supply constraint.

  During Structured Controversy, when teams argue for demand-side solutions, ask them to sketch the policy effect on their supply-constrained graph. Require them to explain why the shift may lower unemployment but worsen inflation further.
