Inflation: Causes and Measurement

Active learning helps students grasp inflation’s causes and measurement by moving beyond abstract definitions into concrete experiences. Students retain concepts better when they see supply disruptions, price pressures, and index calculations play out in real time rather than through lecture alone.

• 45 min · Small Groups

Simulation Game: Inflation Marketplace

Divide class into buyers and sellers with play money. Introduce cost shocks by raising supply costs, prompting price hikes. Groups track purchasing power changes over three rounds and report shifts in wealth between roles.

Analyze how inflation redistributes wealth between lenders and borrowers.

Facilitation Tip

For the Inflation Marketplace simulation, circulate and listen for students who recognize price signals tied to shortages or wage hikes as causal factors.

What to look for

Present students with two scenarios: one describing a period of high aggregate demand and another detailing a sudden oil price shock. Ask them to identify the likely type of inflation in each case and write one sentence explaining why.

Activity 02

• Simulation Game
• 30 min · Pairs

Pairs: Build Your CPI Basket

Pairs select 10 household items and assign base prices from ABS data. Simulate quarterly price changes based on scenarios like wage rises. Calculate index changes and discuss basket limitations.

Explain the trade-offs created by inflation for fixed-income earners.

Facilitation Tip

When students Build Your CPI Basket, provide sample receipts to ground their choices in actual household spending data.

What to look for

Pose the question: 'Imagine you have $1000 saved. If inflation is 5% this year, how much is your money effectively worth in terms of purchasing power at the end of the year?' Facilitate a discussion on how this impacts saving and spending decisions.

Activity 03

Whole Class: Inflation Debate

Assign positions on 'Inflation is always bad' versus 'Low inflation is healthy.' Provide data prompts on RBA targets. Students prepare arguments in buzz groups before full debate with voting.

Justify why a small amount of inflation is considered healthy for an economy.

Facilitation Tip

During the Inflation Debate, assign roles in advance to ensure balanced participation and prevent dominant voices from steering the discussion.

What to look for

On a slip of paper, ask students to define 'real interest rate' in their own words and provide one reason why the Reserve Bank of Australia aims for low, stable inflation.

Activity 04

Individual: Track Local Inflation

Students collect prices for five items over two weeks from shops or apps. Plot personal CPI line graph and compare to national data. Share findings in a class gallery walk.

Analyze how inflation redistributes wealth between lenders and borrowers.

Facilitation Tip

For Track Local Inflation, remind students to use ABS CPI tables for consistent measurement and comparison over time.

A few notes on teaching this unit

Start with cause-and-effect activities before introducing CPI to prevent students from seeing inflation as only a statistical phenomenon. Use role-play and marketplace simulations to build intuition about price pressures, then introduce measurement concepts as a tool for tracking those pressures. Avoid jumping straight into formulas; build the need for the tool first through student experiences.

Students will explain demand-pull and cost-push inflation using real-world triggers, justify the CPI’s structure by adjusting a sample basket, and evaluate its limitations through debate and data analysis. Success is visible when they connect theory to evidence during simulations and discussions.

Watch Out for These Misconceptions

• During Inflation Debate, watch for students who claim inflation is always harmful to the economy.

  Redirect the debate by asking groups to find one benefit of moderate inflation (around 2 percent) and explain how it stabilizes debtors’ real obligations or signals healthy demand, using real examples from the simulation.

• During Inflation Marketplace, watch for students who attribute all price rises to excessive money printing.

  Ask students to identify whether their assigned scenario (e.g., oil shock or rising wages) is a supply or demand issue, then link the outcome to price changes in the marketplace, emphasizing multiple causal pathways.

• During Build Your CPI Basket, watch for students who assume the CPI accurately reflects changes in living standards.

  Have students adjust their basket to account for substitutions (e.g., switching to cheaper rice when beef prices rise) and explain how their revised weights reduce bias, revealing the index’s limitations.
