Market Structures and Competition

Active learning helps students grasp abstract market structures by letting them experience barriers, competition, and interdependence firsthand. Simulations and debates make pricing power, output decisions, and consumer impacts tangible rather than theoretical.

Activity 01

• Case Study Analysis
• 45 min · Small Groups

Market Simulation: Perfect Competition vs Monopoly

Divide class into two markets: one with many small firms bidding identical goods, the other with one dominant seller setting prices. Run 3-4 trading rounds, track prices and sales. Groups debrief on output and consumer surplus differences.

Differentiate between various market structures based on characteristics like number of firms, product differentiation, and barriers to entry.

Facilitation Tip

During Market Simulation, circulate to clarify that identical products in perfect competition prevent firms from setting prices above market rate.

What to look for

Present students with brief descriptions of different industries (e.g., a local bakery, the national airline, a smartphone manufacturer). Ask them to identify the most likely market structure for each and justify their choice based on the number of firms and product type.

Activity 02

• Case Study Analysis
• 35 min · Pairs

Oligopoly Price Game: Kinked Demand

Pairs represent rival firms like supermarkets. Each round, secretly choose prices; reveal simultaneously and calculate profits based on reactions. After 5 rounds, discuss price rigidity and collusion risks.

Analyze how different market structures influence pricing decisions and output levels for firms.

Facilitation Tip

In the Oligopoly Price Game, enforce the kinked demand rule strictly so students see why firms avoid price cuts but copy price hikes.

What to look for

Pose the question: 'If a government wants to increase consumer welfare, should it aim to move all markets towards perfect competition?' Facilitate a class discussion where students debate the pros and cons of different market structures for consumers and producers.

Activity 03

• Case Study Analysis
• 50 min · Small Groups

Case Study Stations: Australian Markets

Set up stations for agriculture (perfect competition), Qantas (oligopoly), and Ausgrid (monopoly). Small groups rotate, analyze data on prices, entry barriers, and welfare impacts, then present findings.

Evaluate the impact of competition and market power on consumer choice and economic efficiency.

Facilitation Tip

At Case Study Stations, assign groups to focus on one Australian market to deepen analysis rather than rushing through all three.

What to look for

On an exit ticket, ask students to define one market structure in their own words and provide one Australian example. Then, ask them to explain one way this market structure affects the price consumers pay for a good or service.

Activity 04

• Formal Debate
• 40 min · Whole Class

Formal Debate: Antitrust Policies

Assign teams to argue for or against regulating oligopolies like Coles and Woolworths. Provide evidence packs; teams prepare 5-minute speeches followed by rebuttals and class vote.

Differentiate between various market structures based on characteristics like number of firms, product differentiation, and barriers to entry.

Facilitation Tip

For the Debate, assign roles in advance so students prepare arguments for or against antitrust policies using evidence from prior activities.

What to look for

Present students with brief descriptions of different industries (e.g., a local bakery, the national airline, a smartphone manufacturer). Ask them to identify the most likely market structure for each and justify their choice based on the number of firms and product type.

A few notes on teaching this unit

Teachers should avoid overwhelming students with too many market types at once; isolate perfect competition and monopoly first, then introduce oligopoly as an advanced comparison. Research shows students learn best when they confront misconceptions directly in simulations rather than through lecture. Always connect abstract models to real industries to prevent detachment from practical relevance.

By the end of these activities, students will compare market structures with evidence from simulations and role-plays. They will explain how barriers, firm numbers, and product types shape prices, output, and consumer choice in real-world contexts.

Watch Out for These Misconceptions

• During Market Simulation: Perfect Competition vs Monopoly, watch for students assuming all markets function like the perfect competition scenario.

  After the simulation, have students compare their experience entering the monopoly market with the perfect competition market, highlighting barriers and pricing limits they encountered in each.

• During Market Simulation: Perfect Competition vs Monopoly, watch for students believing monopolies always set prices as high as possible regardless of regulations.

  During the debrief, present data from regulated monopolies like utilities to show how governments cap prices or require universal service, prompting students to revise their assumptions.

• During Oligopoly Price Game: Kinked Demand, watch for students assuming oligopolies behave like monopolies with full control over prices.

  Use the game’s outcome where firms match price hikes but avoid cuts to show interdependence, then ask students to explain why collusion fails in repeated rounds of the prisoner’s dilemma.
