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.

Learning Objectives

1. Analyze the causes of stagflation by differentiating between demand-pull and cost-push inflation.
2. Evaluate the effectiveness of traditional monetary and fiscal policies in addressing stagflation.
3. Critique the policy dilemmas faced by governments during periods of stagflation, using historical examples.
4. Explain the mechanism by which supply shocks, such as oil price increases, can trigger stagflation.

Case Study Analysis

⏱ 55 min·Small Groups

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.

Prepare & details

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.

Setup: Groups at tables with case materials

Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template

Document Mystery

⏱ 40 min·Whole 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.

Prepare & details

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.

Setup: Groups at tables with document sets

Materials: Document packet (5-8 sources), Analysis worksheet, Theory-building template

• Analyze
• Evaluate
• Self-Management
• Decision-Making

Think-Pair-Share

⏱ 20 min·Pairs

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.

Prepare & details

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.

Setup: Standard classroom seating; students turn to a neighbor

Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs

Teaching This Topic

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.

What to Expect

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

Common Misconception

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.

What to Teach Instead

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.

Common Misconception

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.

What to Teach Instead

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.

Assessment Ideas

Discussion Prompt

After Structured Controversy, ask students in 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.

Quick Check

During Think-Pair-Share, 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.

Exit Ticket

After Case Study Analysis, 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.

Extensions & Scaffolding

• Challenge early finishers to research a modern supply shock (e.g., semiconductor shortages) and present its macroeconomic effects using the same supply-shock framework.
• Scaffolding for struggling students: Provide partially completed aggregate supply and demand graphs with key labels missing, and ask them to add the shock and predict outcomes.
• Deeper exploration: Have students compare the 1973 oil crisis to the 2022 energy shock to identify what’s similar and what’s different in policy responses.

Key Vocabulary

Stagflation	A period of high inflation, high unemployment, and stagnant economic growth occurring simultaneously.
Supply Shock	An unexpected event that suddenly increases or decreases the supply of a commodity or product, leading to price volatility.
Cost-Push Inflation	Inflation that occurs when the cost of producing goods and services increases, forcing businesses to raise prices.
Phillips Curve	An economic concept illustrating an inverse relationship between inflation and unemployment; stagflation challenges this traditional model.
Aggregate Supply	The total supply of goods and services that firms in a national economy plan on selling during a specific time period.
