Inflation: Causes and Types

Students often see inflation as a distant economic concept, but active simulations and real-world data make it immediate and relevant. By stepping into roles as consumers, producers, and policymakers, students move beyond abstract definitions to grasp how inflation shapes decisions in Australian markets every day.

Activity 01

• Simulation Game
• 45 min · Small Groups

Simulation Game: Demand-Pull vs Cost-Push Scenarios

Divide class into markets with limited goods. In round 1, inject extra buyer money to simulate demand-pull; track price bids. In round 2, raise supplier costs; observe price changes. Groups debrief on causes and effects using charts.

Differentiate between demand-pull and cost-push inflation.

Facilitation Tip

During the Simulation, assign each student a role card with a budget and set clear time limits so bidding reflects real-time price pressure without dragging on too long.

What to look for

Present students with two brief scenarios: Scenario A describes a surge in consumer spending after lockdowns, and Scenario B describes a sharp increase in global oil prices. Ask students to identify which scenario best illustrates demand-pull inflation and which illustrates cost-push inflation, and to provide one sentence justifying each choice.

Activity 02

• Case Study Analysis
• 30 min · Pairs

Data Hunt: Australian Inflation Trends

Provide RBA datasets on CPI, wages, and GDP. Pairs graph demand-pull indicators like retail sales against cost-push like oil prices. Discuss correlations and policy responses in a class share-out.

Analyze the incentives driving consumer and business behavior during periods of high inflation.

Facilitation Tip

For the Data Hunt, provide pre-selected RBA or ABS datasets with guided questions to prevent students from becoming overwhelmed by raw data.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you are advising the Treasurer of Australia. What are the two biggest risks posed by high inflation to the average Australian household, and what is one policy action the government could consider to mitigate these risks?'

Activity 03

• Formal Debate
• 40 min · Whole Class

Formal Debate: Inflation Consequences

Assign teams to argue 'mild inflation benefits growth' versus 'inflation always harms stability.' Use evidence from Aussie history like 1970s stagflation. Vote and reflect on incentives.

Explain how inflationary expectations influence economic decisions.

Facilitation Tip

In the Debate, assign roles in advance so students prepare balanced arguments and stay focused on economic consequences rather than personal opinions.

What to look for

On an index card, have students write down one economic decision they or their family might make differently if they expected inflation to reach 7% next year. Then, ask them to explain how this decision is influenced by their inflationary expectations.

Case Study Analysis: Recent Aussie Inflation

Examine 2022 inflation spike. Individuals annotate articles on causes, then small groups propose RBA actions. Present and peer critique.

Differentiate between demand-pull and cost-push inflation.

A few notes on teaching this unit

Teach this topic through layered inquiry: start with simulations to build intuitive understanding, then use data to test hypotheses, and finally apply knowledge in debates and case studies. Avoid rushing to policy solutions before students have wrestled with the mechanics of price changes. Research shows that students retain inflation concepts better when they experience the pressures that drive price shifts firsthand.

By the end of these activities, students should confidently distinguish demand-pull from cost-push inflation, explain their causes in concrete terms, and evaluate consequences using real Australian data. Successful learning appears as clear comparisons, accurate data interpretation, and thoughtful policy reasoning.

Watch Out for These Misconceptions

• During the Simulation: Demand-Pull vs Cost-Push Scenarios, watch for students assuming inflation only happens when money supply increases.

  During the Simulation, circulate while students bid in their assigned markets and redirect conversations by asking, 'Where is the extra demand coming from?' and 'Are any input costs rising here?' to highlight real demand and supply pressures.

• During the Debate: Inflation Consequences, watch for students claiming that demand-pull inflation only harms consumers.

  During the Debate, pause the discussion when this claim arises and ask business role-players to share how rising prices squeeze their profit margins, prompting students to revise their understanding of shared impacts.

• During the Data Hunt: Australian Inflation Trends, watch for students grouping demand-pull and cost-push inflation together as equally harmful.

  During the Data Hunt, have groups present their findings on a shared whiteboard, labeling which periods show demand-led growth versus cost shocks, then facilitate a comparison to reveal why consequences differ.
