Deflation and Stagflation

Active learning helps students grasp deflation and stagflation by making abstract economic forces concrete. Simulations let them feel the real-world trade-offs, while case studies connect historical events to theoretical models. These experiences build durable understanding beyond textbook definitions.

Activity 01

• Simulation Game
• 45 min · Small Groups

Simulation Game: Deflation Decision Stations

Set up stations for consumer, business, bank, and government roles. Present deflation scenarios; groups decide actions like spending or lending, then rotate to see chain reactions. Debrief with class chart of outcomes.

Explain the economic dangers of persistent deflation.

Facilitation Tip

In Deflation Decision Stations, circulate with a checklist to ensure each group documents both their chosen policy and its immediate and delayed consequences.

What to look for

Pose the question: 'Imagine you are advising the Canadian government during a period of high inflation and rising unemployment (stagflation). What are the two main policy challenges you face, and why is it difficult to address both simultaneously?' Facilitate a class discussion where students explain the conflicting goals of anti-inflationary and anti-recessionary policies.

Activity 02

• Case Study Analysis
• 35 min · Pairs

Case Study Analysis: 1970s Stagflation Graphs

Provide Canadian and global data sets on inflation, GDP, unemployment. Pairs plot AD-AS shifts, identify shocks, propose policies. Share findings in a whole-class gallery walk.

Analyze the policy challenges posed by stagflation.

Facilitation Tip

For the 1970s Stagflation Graphs, provide colored pencils so students can annotate supply shocks and policy interventions directly on printed charts.

What to look for

Provide students with a short case study describing an economy with falling prices and decreasing demand. Ask them to write two sentences explaining why consumers might delay purchases and one sentence explaining how this impacts businesses. Collect and review responses for understanding of deflation's impact on spending and investment.

Activity 03

• Case Study Analysis
• 50 min · Whole Class

Policy Debate: Stagflation Solutions

Divide class into teams for fiscal expansion, monetary tightening, or supply-side reforms. Each presents evidence from models, rebuts opponents. Vote on best approach with rationale.

Predict the impact of falling prices on consumer and business investment.

Facilitation Tip

During the Policy Debate, enforce a two-minute speaking limit per turn to keep the discussion focused and give every student a chance to contribute.

What to look for

On an index card, ask students to define 'stagflation' in their own words and provide one example of a potential cause. Then, ask them to identify one specific consequence for Canadian households during such an economic period.

Activity 04

• Case Study Analysis
• 30 min · Individual

Prediction Mapping: Price Fall Impacts

Individuals map falling prices' effects on spending, debt, investment using flowcharts. Pairs merge maps, discuss revisions. Class compiles into shared economic cycle diagram.

Explain the economic dangers of persistent deflation.

Facilitation Tip

In Prediction Mapping, require students to pair their price-fall scenarios with real business examples from Ontario’s economy to ground abstract concepts.

What are the two main policy challenges you face, and why is it difficult to address both simultaneously?'

A few notes on teaching this unit

Teach deflation by starting with familiar scenarios, like waiting for sales to end before buying a phone. Avoid rushing to solutions—instead, let students experience the uncertainty of interdependent choices. For stagflation, emphasize the breakdown of the Phillips curve by comparing historical data with current events. Research shows that students retain complex systems best when they first encounter them through role-based simulations before moving to analytical tasks.

Students will explain the causes and effects of deflation and stagflation, trace feedback loops in economic systems, and evaluate policy trade-offs. They will use evidence from simulations, graphs, and debates to support their reasoning.

Watch Out for These Misconceptions

• During Deflation Decision Stations, watch for students assuming that lower prices always benefit consumers.

  Ask each group to track how sustained price drops affect household budgets, debt burdens, and purchase timing in their simulation notes, then discuss these outcomes in a whole-class debrief.

• During Policy Debate: Stagflation Solutions, watch for students proposing higher interest rates as a universal fix.

  Have debaters use the Phillips curve graphs from the 1970s case study to explain why rate hikes worsen unemployment, requiring them to cite specific data points from their charts.

• During Prediction Mapping: Price Fall Impacts, watch for students linking falling prices directly to higher profits.

  Direct students to add a 'fixed costs' layer to their maps, then calculate how rising relative costs erode margins in their sample businesses.
