Degrees of Competition

Within a private enterprise system, not all industries are equally competitive. Economists identify four degrees of competition that describe how much market power any single firm holds and how prices are determined.

The Spectrum

Degree	Number of Firms	Products	Price Power	Canadian Example
Perfect Competition	Very many, all small	Identical	None — price set by market	Wheat farming
Monopolistic Competition	Many, small or large	Similar but differentiated	Some — via branding	Coffee shops, clothing
Oligopoly	Few, very large	Similar or differentiated	Significant — interdependent	Auto, steel, banking
Monopoly	One	Unique	Full control	Canada Post (letter mail)

Perfect Competition

Two key conditions:

1. All firms must be small
2. The number of firms in the industry must be large

Because no firm can influence price, prices are determined entirely by supply and demand. Additional properties: products are viewed as identical, buyers and sellers know market prices, easy market entry/exit.

Canadian agriculture (wheat, canola) is the textbook example — one farm’s wheat is indistinguishable from another’s.

Monopolistic Competition

Many sellers who differentiate their products through branding, atmosphere, features, or marketing. The differentiation gives each firm some pricing power — a Ralph Lauren Polo shirt can command $20 more than a similar shirt from an unknown brand at The Bay. Businesses can still enter and leave the market easily.

Oligopoly

A handful of very large firms dominate. Entry is difficult because it requires massive capital investment. Because firms are interdependent, price cuts by one firm force all others to match — so oligopolies typically compete on features and service rather than price. Prices end up remarkably similar across the industry.

Industries: automobile, rubber, steel, Canadian banking.

Monopoly

A single producer with full pricing power. In Canada, monopolies are regulated to prevent abuse — this is the primary motivation for the Competition Act. Natural monopolies (utilities, postal service) are often Crown corporations.

How It Appears Per Course

ADMN 201

Degrees of competition are essential background for understanding pricing strategy, market entry decisions, and why government regulation exists. Most Canadian industries covered throughout the course (banking, retail, manufacturing) fall into oligopoly or monopolistic competition.

Cross-Course Connections

PrivateEnterprise — competition is one of the four pillars of private enterprise
BusinessGovernmentRelations — the Competition Act is the government’s primary tool for keeping competition healthy
SupplyAndDemand — degree of competition determines how much a firm can deviate from the equilibrium price

Key Points for Exam/Study

• Perfect competition: many small firms, identical products, zero pricing power (e.g., wheat)
• Monopolistic competition: many firms, similar but differentiated products, some pricing power (e.g., coffee shops)
• Oligopoly: few large firms, high barriers to entry, interdependent pricing (e.g., auto, banking)
• Monopoly: one firm, complete pricing control — regulated by government via Competition Act
• Spectrum runs left (most competitive) → right (least competitive)
• Profits motivate starting a business; competition motivates operating it efficiently

Open Questions

• Is the Canadian telecom industry an oligopoly or approaching monopoly in some regional markets?
