The competitive environment and market structure

A competitive environment describes how many rival businesses there are and how aggressively they compete. AQA expects you to understand the four broad market structures, the dimensions of competition, and how risk varies with each.

Four market structures

1. Perfect competition

• Many small firms.
• Identical products.
• No single firm can influence price.
• Easy entry/exit.
• Examples: agricultural commodities (wheat, milk).

2. Monopolistic competition

• Many firms.
• Differentiated products (branding, quality, design).
• Each firm has a small price-setting power.
• Easy entry.
• Examples: restaurants, hairdressers, takeaways, clothing brands.

3. Oligopoly

• Few large firms dominate.
• Decisions are interdependent — one firm's price cut triggers rivals' response.
• Brand building, marketing, customer service crucial.
• Difficult entry (high capital, brand-building cost).
• Examples: UK supermarkets (Tesco, Sainsbury's, Asda, Morrisons, Aldi, Lidl); UK banks; mobile networks.

4. Monopoly

• One dominant firm (legally, >25 % share).
• Price-maker.
• Often regulated.
• Hard or impossible for new entrants.
• Examples: Royal Mail (letters, until liberalisation); Network Rail; Microsoft Windows in OS market.

Dimensions of competition

Businesses compete on four main fronts:

Price

• Price competition — supermarkets cutting prices, airline fare wars.
• Penetration pricing — low launch price to grab market share.
• Price wars — bad for everyone but rivals can't afford not to match.

Quality

Often the deciding factor for premium customers.

• Materials — Burberry, Apple use higher-quality components.
• Build / craftsmanship — German cars famously well-built.
• Reliability — Toyota's reputation for never breaking down.

Customer service

• Personal touch (small businesses, John Lewis).
• After-sales support (Amazon's free returns).
• Speed of response (Domino's pizza tracker).
• Helpful, knowledgeable staff (Apple Genius Bar).

USP (unique selling point)

The one thing a business does differently or better:

• Innogen — UK's only certified vegan baby food brand.
• Pret A Manger — fresh, never-frozen ingredients.
• Tesla — zero-emissions luxury electric cars.

A clear USP helps a business avoid head-on price competition.

How competition affects business decisions

When competition is high

• Prices kept low — thin margins.
• Heavy investment in marketing, branding, USP.
• Constant innovation — new products, store concepts.
• Customer service stronger.
• Lower profits per unit, but volume can compensate.

When competition is low (monopoly / oligopoly)

• Prices higher.
• Less innovation pressure.
• Less customer service investment (until regulation forces it).
• Higher profits.
• But: regulator scrutiny CMA, reputational risk, customer dissatisfaction.

Risk in different markets

Low risk

• Stable, established markets (utilities, supermarkets).
• Predictable demand.
• Mature regulation.

High risk

• Fast-changing tech markets.
• Fashion / fads.
• Cyclical / discretionary spending (luxury cars, holidays).
• New regulation (vape laws 2025).
• Globally exposed (commodities).

Real-world examples

• UK supermarket war 2024 — Aldi and Lidl took market share from "Big Four"; all retailers cut prices on essentials and launched value lines.
• Streaming wars — Netflix vs Disney+ vs Amazon Prime vs Apple TV+; each spending billions on original content.
• Premier League — top tier of football; oligopoly of Big Six (Man City, Liverpool, Arsenal, Chelsea, Man Utd, Tottenham) chase Champions League revenue.
• High-street decline — coffee shop oligopoly (Starbucks, Costa, Caffè Nero) survived; Wilko, BHS, Debenhams collapsed.

Examiner tips

For 6+ mark questions about competition, identify the market structure, name two or three competitors, then explain how the business competes (price/quality/service/USP) and the risks. End with a judgement on whether the business is well-positioned.
