Active learning ideas
This topic contrasts the two extremes of market structures: Perfect Competition and Monopoly. Students learn the theoretical characteristics of a perfectly competitive market, many small firms, identical products, and no barriers to entry, and compare them to a monopoly, where a single firm dominates. This comparison is essential for understanding how market power affects prices, choice, and efficiency.
Activity 01
One group acts as a monopoly with 'patents' and 'high setup costs.' Another group tries to enter the market. The class discusses why it's nearly impossible to compete, illustrating barriers to entry.
What are the assumptions of perfect competition?
Activity 02
Post large Venn diagrams around the room. In groups, students move from station to station adding characteristics, pros, and cons of Perfect Competition vs. Monopoly, using different colored markers.
How does a monopoly maintain its market power?
Activity 03
Pairs discuss potential benefits of monopolies, such as natural monopolies in water or rail, or high R&D spending in pharma. They present their 'defense' or 'prosecution' of a monopoly to the class.
How do outcomes differ for consumers in these two structures?
A few notes on teaching this unit
Watch Out for These Misconceptions
Perfect competition exists in the real world.
It is a theoretical model used as a benchmark. Discussing why real markets (like a farmers' market) still have slight differences helps students see the model's purpose without confusing it with reality.
Monopolies can charge any price they want.
Even a monopoly is constrained by the demand curve; if the price is too high, nobody will buy. Using a demand schedule in a group exercise helps students find the 'optimal' (not infinite) monopoly price.
