Monopoly and Market Power

Active learning works for this topic because monopoly pricing requires students to visualize abstract curves and trade-offs before grasping their real-world impacts. Role-playing and graphing transform abstract economic models into concrete decisions, helping students connect marginal revenue, price setting, and welfare losses through direct experience rather than passive listening.

Activity 01

• Simulation Game
• 45 min · Small Groups

Simulation Game: Monopoly Pricing Challenge

Divide class into firms; one acts as monopolist setting candy prices while others bid as consumers. Track sales, profits, and surplus over rounds. Debrief with graphs comparing to competitive pricing.

Analyze how a monopoly's market power affects consumer welfare.

Facilitation Tip

During the Monopoly Pricing Challenge, circulate and ask groups probing questions like, 'How does your price change if demand drops by 20%?' to push beyond surface-level strategy.

What to look for

Present students with a graph showing a monopoly's demand, marginal revenue, marginal cost, and average total cost curves. Ask them to identify the profit-maximizing price and quantity, and shade the area representing deadweight loss. Students submit their labeled graphs.

Activity 02

• Case Study Analysis
• 30 min · Pairs

Graphing Lab: Monopoly vs Competition

Provide demand and cost data; pairs plot curves for monopoly and perfect competition outcomes. Calculate deadweight loss. Share findings in a class gallery walk.

Explain the sources of monopoly power.

Facilitation Tip

In the Graphing Lab, provide colored pencils and large graph paper to help students distinguish curves and avoid color confusion when analyzing deadweight loss.

What to look for

Pose the question: 'Should governments break up large, profitable companies that dominate their markets, or regulate them instead?' Facilitate a class debate where students must use economic reasoning to support their arguments, referencing concepts like efficiency, consumer welfare, and barriers to entry.

Activity 03

• Case Study Analysis
• 50 min · Small Groups

Policy Debate: Regulate or Not?

Assign roles for/against regulating a Canadian telecom monopoly. Groups prepare arguments on welfare effects using graphs. Vote and reflect on policy strengths.

Critique government policies designed to regulate monopolies.

Facilitation Tip

For the Policy Debate, assign roles in advance (e.g., consumer advocate, CEO, regulator) and provide a two-minute prep time to ensure all students contribute meaningfully.

What to look for

Ask students to write down two distinct sources of monopoly power and provide a brief example for each. Then, have them explain in one sentence why a monopoly's price is typically higher than in a competitive market.

Activity 04

• Jigsaw
• 40 min · Small Groups

Jigsaw: Real Monopolies

Assign Canadian cases like Enbridge pipelines to expert groups. Experts teach peers about power sources and regulations. Class synthesizes common welfare themes.

Analyze how a monopoly's market power affects consumer welfare.

Facilitation Tip

During the Case Study Jigsaw, assign each group a specific real-world monopoly (e.g., Hydro One, Google Search) and require them to present a 60-second elevator pitch on its market power source.

What to look for

Present students with a graph showing a monopoly's demand, marginal revenue, marginal cost, and average total cost curves. Ask them to identify the profit-maximizing price and quantity, and shade the area representing deadweight loss. Students submit their labeled graphs.

A few notes on teaching this unit

Experienced teachers approach this topic by starting with simulations to build intuition about pricing power, then layering in graphing to formalize the model. Avoid presenting the monopoly outcome as purely negative; instead, use natural monopoly examples to highlight efficiency trade-offs. Research suggests students grasp deadweight loss better when they calculate it themselves rather than watch a lecture, so always pair abstract explanations with hands-on activities.

Successful learning looks like students accurately identifying profit-maximizing prices on graphs, debating regulation trade-offs using economic reasoning, and connecting monopoly outcomes to consumer welfare and policy responses. They should articulate why monopolies produce less output at higher prices than competitive markets, and critique solutions like price caps or antitrust laws with evidence from simulations and case studies.

Watch Out for These Misconceptions

• During the Monopoly Pricing Challenge, watch for students who assume the highest price always yields the highest profit.

  Use the simulation’s profit calculator to show students how revenue changes at different price points, then have them graph profit against price to identify the true maximum.

• During the Case Study Jigsaw, watch for students who claim all monopolies harm consumers with no benefits.

  In their group discussions, prompt them to consider natural monopolies like utilities, and use their presentations to compare efficiency gains with consumer trade-offs.

• During the Policy Debate, watch for students who assume government regulation always solves monopoly problems effectively.

  Have groups test their arguments using the simulation’s outcome data, showing how price caps can create shortages or inefficiencies in practice.
