Competition in a Nutshell
Competition is the rivalry between businesses selling similar products to the same customers, each trying to win a larger share of sales, revenue or profit. It brings lower prices, efficiency, innovation and choice, but also price wars, higher marketing costs, business failure and pressure on staff and suppliers.
Competition Definition
Competition is the rivalry between businesses selling similar products to the same customers. Each firm tries to win a larger share of sales, revenue or profit. Customers choose, and businesses respond. Why does a meal deal cost £3.85 in one supermarket and £3.50 in the one across the road? Why did Netflix add a cheaper plan with adverts once Disney+ and Amazon Prime Video began to grow? Every business you buy from is fighting for your money.
Markets differ in how fierce the fight is. In a highly competitive market, such as hairdressers in a town centre, there are lots of sellers and low barriers to entry. In an oligopoly, a few large firms dominate, as UK supermarkets do: Tesco, Sainsbury’s, Asda, Aldi and Lidl. In a monopoly, one firm controls the market. The more rivals there are, the less power each one has over price.
Firms fight in two ways. Price strategies include discounts, price matching and loss leaders, and Aldi built its UK growth on low prices. Non-price strategies avoid a price war and include branding, quality, customer service, location and product innovation. Apple rarely cuts prices. It wins through design, brand loyalty and its ecosystem.

Competition Characteristics/Features
- Rival firms: two or more businesses targeting the same customers.
- Customer choice: buyers can switch to an alternative.
- Substitutes: products that meet the same need, such as Coca-Cola and Pepsi.
- Barriers to entry: obstacles that stop new firms joining, such as high start-up costs.
- Market power: the ability of a firm to set prices without losing many customers.
- Price and non-price strategies: firms compete on cost and on quality, branding and service.
Examples of Competition
Lidl and Aldi forced the larger supermarkets to launch price-matching schemes, so shoppers pay less and the big four have to cut costs to protect margins.
Dyson invested heavily in research to beat older vacuum brands. A new product created a unique selling point, allowing a higher price and stronger profit.
Wilko collapsed in 2023 after struggling against discount rivals such as B&M and Home Bargains, showing how weaker firms can be forced out.
Advantages & Disadvantages of Competition
Advantages
Lower prices for consumers
Rival firms cut prices to win customers. Lidl and Aldi forced the larger supermarkets to launch price-matching schemes. Shoppers pay less, which raises their real income and spending power.
Pressure to improve efficiency
If costs are too high, a firm cannot match rivals’ prices. This pushes managers to cut waste and improve capacity utilisation. Lower unit costs protect profit margins, so the business survives longer.
Innovation and new products
Firms must stand out. Dyson invested heavily in research to beat older vacuum brands. New products create a unique selling point, which allows a higher price and stronger profit.
Better quality and service
When customers can leave easily, firms must keep them happy. Online retailers offer next-day delivery and free returns. Higher satisfaction leads to repeat purchases, which increases revenue over time.
Wider customer choice
More firms means more variety. The coffee market offers Costa, Starbucks, Greggs and independent cafés. Choice lets new businesses find a niche market, so entrepreneurs can enter with a specialist product.
Motivation for entrepreneurs to grow
Strong rivals push owners to expand and plan carefully. A small business that survives a tough market builds stronger systems, which makes it more attractive to investors and helps it raise finance for growth.
Disadvantages
Price wars reduce profit
When firms keep cutting prices, margins shrink. Low-cost airlines such as Ryanair and easyJet often compete on fares. Lower profit means less retained profit to reinvest, which slows growth.
Higher marketing costs
Firms spend more on advertising to protect market share. This raises fixed costs, and if sales do not rise to match, the break-even point increases and profit falls.
Business failure
Weaker firms may be forced out. Wilko collapsed in 2023 after struggling against discount rivals such as B&M and Home Bargains. Closure means job losses and lost investment for owners.
Short-term thinking
Managers may focus on beating rivals this quarter rather than planning for five years. They might cut training or research to save money, which weakens the business in the long run.
Pressure on staff and suppliers
To cut costs, firms may squeeze supplier prices or overwork employees. Low morale raises staff turnover, and recruitment and training costs then rise, which hurts efficiency.
Barriers for small entrepreneurs
Large rivals benefit from economies of scale. A new independent bookshop cannot match Amazon’s prices. Without a clear niche, the start-up struggles to generate enough revenue to cover costs.
Market Share and Concentration Ratios: Technique and Worked Examples
Market share (%) = firm’s sales ÷ total market sales × 100. A café sells £120,000 in a town where total café sales are £600,000: 120,000 ÷ 600,000 = 0.2, then × 100 = 20%. A bakery with sales of £90,000 in a £450,000 market also has 20%.
Concentration ratio adds the market shares of the largest firms. A four-firm concentration ratio (CR4) adds the top four: CR4 = share of firm 1 + firm 2 + firm 3 + firm 4. If the top four have 30%, 25%, 15% and 10%, the CR4 is 80%. For a smartphone market with shares of 22%, 20%, 13% and 9%, CR4 = 64%. A high ratio, roughly above 60%, suggests an oligopoly, while a low ratio suggests many rivals.
In the UK, the Competition and Markets Authority uses a share-of-supply test of 25% when deciding whether a merger may raise competition concerns, so a firm with a share at or above that level attracts scrutiny.
Common Mistakes
Mixing up the firm’s sales and the market’s sales, forgetting the % sign, and describing a high CR4 without linking it to market structure.
Memory Trick
“Me over all, times a hundred.” Always state units and show workings: method marks are often available even if the final answer is wrong.
Evaluation link. The impact of rivalry always depends on the market, the objective, the situation and the firm’s response, such as whether it can compete on non-price factors.
Evaluating the Usefulness of Competition
For evaluation (AO4), the impact of rivalry always depends on several factors. A strong evaluation says what matters most and why. For example: “The most important factor is brand loyalty, because Apple’s loyal customers are less sensitive to price, so rival discounts have limited impact.”
Market
Is the market growing or shrinking? Growth softens the impact of new rivals, while a shrinking market intensifies the fight for each customer.
Objective
Does the firm aim for survival, profit or growth? A firm seeking survival may accept lower prices, while one seeking premium profit will avoid a price war.
Situation
Does it have a strong brand, cash reserves or a unique selling point? These give a firm the strength to withstand rivals.
Response
Can it compete on non-price factors instead of price? Differentiation through quality, service or innovation avoids a margin-destroying price war.

Practice GCSE Exam-Style Questions for Competition with a Case Study
Read the following case study, then answer the questions below.
Rye Lane Bakery is an independent bakery in a market town, owned by Imogen Hart. Last year it made sales of £90,000. Total bakery sales in the town were £450,000. A new Greggs opened 200 metres away in January. Greggs sells sausage rolls at a lower price than Rye Lane Bakery. Imogen is considering two options: cut her prices by 15%, or launch a range of handmade sourdough and celebration cakes.
- Calculate Rye Lane Bakery’s market share. Show your working.2 marks
- Explain one way Greggs’ arrival could affect Rye Lane Bakery.3 marks
- Analyse the benefits to Rye Lane Bakery of using non-price strategies.6 marks
- Evaluate whether Imogen should cut her prices or launch the specialist range. Justify your answer.12 marks
For question 1: (90,000 ÷ 450,000) × 100 = 20%.
For the 12-mark question, avoid sitting on the fence. A strong answer might argue that a price cut is risky because Greggs gains from economies of scale and can always undercut a small baker, while sourdough and celebration cakes are harder to copy. The final judgement could depend on whether local customers value quality enough to pay more. Students summarise both sides, then fail to decide.
Practice A-Level Exam-Style Questions for Competition with a Case Study
Read the following case study, then answer the questions below.
The global smartphone market is dominated by a few firms. Apple and Samsung lead, with Xiaomi, OPPO and vivo close behind. Apple competes through premium branding and its ecosystem of services. Xiaomi built its growth on lower prices and strong online sales in Asia. Development costs are very high, and patents protect key technologies. In this case study, assume the top four firms hold market shares of 22%, 20%, 13% and 9%. A new entrant, Novaphone, plans to launch a £250 handset with a two-day battery life.
- Calculate the four-firm concentration ratio and state what it suggests about market structure.3 marks
- Explain one barrier to entry Novaphone faces.4 marks
- Analyse how Apple’s non-price strategies protect its profit margins.9 marks
- To what extent is Novaphone likely to succeed in this market?16 marks
- Evaluate whether intense rivalry is always good for consumers.20 marks
For question 1: 22 + 20 + 13 + 9 = 64%. This suggests an oligopoly, as a few firms control most of the market.
For the 16-marker, weigh the barriers against Novaphone’s unique selling point. Battery life is a real customer need, but Apple users are locked into iCloud and the App Store, so switching costs are high. A strong judgement might say success depends on targeting price-sensitive buyers in growing markets, rather than fighting Apple head-on.
For the 20-marker there is no case study, so use your own examples. Build linked chains of cause and effect, then finish with a clear conclusion.
