Welcome to the Spectrum of Competition
Welcome to your study notes for AS 2: Growing the Business! When a business wants to expand, it cannot operate in a bubble. It must constantly look at its rivals, understand the environment it operates in, and measure how well it is performing compared to others.
In this chapter, we will explore what competition means, how to calculate and analyse key market metrics (like market size, market share, and market growth), and how different market structures shape the way businesses make decisions. Don't worry if some of these economic concepts seem tricky at first — we will break everything down step by step with clear formulas, real-world examples, and helpful tips!
1. Measuring the Market: Size, Share, and Growth
Before a business can plan for growth, it needs to measure the market. There are three essential metrics you must master for your exam: market size, market share, and market growth.
A. Market Size
Market size represents the total value or volume of sales in a specific market over a given period (usually one year).
• Value: The total amount of money spent by customers in the market (e.g., the UK coffee shop market is worth \(£4\text{ billion}\)).
• Volume: The physical quantity of units sold across the whole market (e.g., \(2.5\text{ billion}\) cups of coffee sold in a year).
Why does market size matter? Knowing the market size helps a business decide whether a market is big enough to enter or if it is too small to generate worthwhile profits.
B. Market Share
Market share measures the proportion of total market sales that is held by a single business or brand. It is almost always expressed as a percentage.
The Formula:
\(\text{Market Share (\%)} = \left( \frac{\text{Sales of the Business}}{\text{Total Market Sales}} \right) \times 100\)
Note: You can calculate market share using either sales revenue (\(£\)) or sales volume (units), but make sure you use the same measure for both the business and the total market!
Step-by-Step Worked Example:
Imagine the total UK crisp market is worth \(£1,200\text{ million}\) in a year. A crisp company, Crunchy Bites, achieves sales revenue of \(£180\text{ million}\) during that same year.
Step 1: Identify the business sales = \(£180\text{ million}\).
Step 2: Identify the total market sales = \(£1,200\text{ million}\).
Step 3: Apply the formula:
\(\text{Market Share} = \left( \frac{180}{1200} \right) \times 100 = 0.15 \times 100 = 15\%\)
Crunchy Bites holds a \(15\%\) market share.
Why is Market Share Important?
• Market Leader Status: The business with the highest market share is the market leader, often enjoying brand dominance and retailer power.
• Economies of Scale: A larger share means higher output, which helps lower average costs.
• Pricing Power: Firms with a strong market share often have more freedom to set prices.
C. Market Growth
Market growth measures the percentage increase in the size of the overall market over a specific period.
The Formula:
\(\text{Market Growth (\%)} = \left( \frac{\text{Market Size in Current Year} - \text{Market Size in Previous Year}}{\text{Market Size in Previous Year}} \right) \times 100\)
Step-by-Step Worked Example:
In 2023, the market for electric scooters was worth \(£50\text{ million}\). In 2024, it expanded to \(£65\text{ million}\).
Step 1: Calculate the change in size: \(£65\text{m} - £50\text{m} = £15\text{m}\).
Step 2: Divide the change by the original (previous) year: \(\frac{15}{50} = 0.3\).
Step 3: Multiply by \(100\):
\(\text{Market Growth} = 0.3 \times 100 = 30\%\)
The market grew by \(30\%\).
Quick Review:
• Growing Market: New customers are entering the market; businesses can increase sales without necessarily taking customers from rivals.
• Static or Declining Market: Total sales are flat or falling; a business can only grow by actively stealing market share from competitors.
2. Competition in the Business Environment
Competition occurs when two or more businesses attempt to win the custom of the same target audience. Competition directly influences how a business behaves, sets prices, and operates.
How Competition Influences a Business Organisation
When competition increases, a business must adapt across several areas:
• Pricing Strategies: Intense competition often forces firms to lower prices, offer discounts, or use penetration pricing to stay attractive to consumers.
• Product Differentiation and Innovation: Businesses must invest in Research & Development (R&D) to create unique selling propositions (USPs) and make their products stand out.
• Promotion and Advertising: Firms need to spend more on creative marketing campaigns to build strong brand loyalty.
• Customer Service: Offering superior after-sales support, free returns, or loyalty schemes helps retain existing customers.
• Cost Efficiency: To maintain profit margins when prices are pushed down, firms must reduce waste, streamline production, and improve productivity.
Did You Know? Competition isn't always bad for businesses! Healthy competition forces companies to innovate, improve quality, and operate more efficiently, which can make them much stronger in the long run.
3. Degree of Competition: The Spectrum of Market Structures
In business studies, markets are classified along a spectrum of competition based on how many firms operate in the industry and how much control they have over prices. At one end, there is fierce competition with thousands of tiny sellers; at the other end, a single firm controls everything.
The Four Key Market Structures
A. Perfect Competition
This is a theoretical ideal where competition is at its absolute maximum.
• Number of Firms: Very large number of small buyers and sellers.
• Type of Product: Identical (homogeneous) products with no branding or differentiation (e.g., raw agricultural commodities like wheat or apples).
• Barriers to Entry/Exit: None; firms can freely join or leave the industry.
• Pricing Power: Businesses are price takers — they must accept the prevailing market price set by supply and demand.
• Knowledge: Perfect knowledge exists; consumers and producers have full information about prices and quality.
B. Monopolistic Competition
This is a very common, real-world market structure where many businesses compete by selling products that are slightly different from one another.
• Number of Firms: Many buyers and sellers.
• Type of Product: Differentiated products through branding, design, quality, or packaging (e.g., hairdressers, local restaurants, clothing boutiques).
• Barriers to Entry/Exit: Low barriers to entry.
• Pricing Power: Some pricing power because brand loyalty allows firms to charge a slight premium without losing all their customers.
C. Oligopoly
An oligopoly occurs when a market is dominated by a small number of large, powerful firms.
• Number of Firms: A few dominant firms holding a high market concentration ratio (e.g., UK supermarkets like Tesco, Sainsbury's, and Asda; mobile phone networks; petrol retailers).
• Type of Product: Can be differentiated (e.g., cars, smartphones) or similar (e.g., petrol).
• Barriers to Entry/Exit: Very high barriers (e.g., high capital start-up costs, heavy advertising budgets, established brand loyalty).
• Interdependence: The actions of one firm directly trigger reactions from rivals. If one supermarket cuts prices, others quickly match it.
• Non-Price Competition: To avoid destructive price wars that erode profits, oligopolies heavily rely on non-price competition (loyalty cards, special promotions, premium packaging, celebrity endorsements).
D. Monopoly
In pure theory, a monopoly is a market structure with only a single supplier. Under UK law and competition regulation, a firm is considered to have a monopoly position if it controls \(25\%\) or more of the total market share.
• Number of Firms: One single dominant seller (or one firm dominating over a quarter of the market).
• Type of Product: Unique product with no close substitutes (e.g., national rail track infrastructure, water utility networks).
• Barriers to Entry/Exit: Extremely high or insurmountable barriers (e.g., legal patents, natural monopolies, huge infrastructure costs).
• Pricing Power: The firm is a price maker — it has substantial power to influence price or supply, though it must still respect consumer demand.
Memory Aid for the Spectrum:
Think of the spectrum as a sliding scale from left (highest competition) to right (least competition):
Perfect Competition \(\rightarrow\) Monopolistic Competition \(\rightarrow\) Oligopoly \(\rightarrow\) Monopoly

4. Factors Determining the Degree of Competition in a Market
Why do some industries have thousands of rivals while others only have two or three? The degree of competition in any market is shaped by several key factors:
• 1. Barriers to Entry and Exit:
If it is cheap and simple to set up a new business (e.g., an online drop-shipping store), many firms will enter, increasing competition. If setting up requires millions in machinery or regulatory licensing (e.g., commercial airlines or pharmaceutical manufacturing), competition remains low.
• 2. Number and Size of Competitors:
A market with many small firms will experience high price competition. A market dominated by two or three giant conglomerates often shifts towards brand-focused, non-price competition.
• 3. Degree of Product Differentiation:
When products are standardized, customers base their buying decisions entirely on price, intensifying rivalry. When products have strong branding and unique features, businesses can protect their market share from direct price competition.
• 4. Customer Switching Costs:
If it is effortless for a customer to switch from Brand A to Brand B (e.g., buying chocolate bars), competition is fierce. If switching costs are high (e.g., changing accounting software or long-term broadband contracts), existing firms face less immediate competitive threat.
• 5. Availability of Substitutes:
The presence of readily available alternative products limits a firm's ability to raise prices. If train tickets become too expensive, passengers can switch to coaches, driving, or domestic flights.
• 6. Legal Protections and Government Regulations:
Patents, copyrights, and exclusive operating licences prevent rivals from copying products, creating legal barriers that restrict competition for a set period.
Key Takeaways for Exam Success
• Always show your workings: In calculation questions for market share or market growth, write down the formula, show every step, and state the correct unit (\(\%\) or \(£\)).
• Understand the difference: Market size is the whole pie; market share is a single business's slice of that pie; market growth is how fast the whole pie is getting bigger.
• Link market structure to strategy: In an oligopoly, explain why firms prefer non-price competition over price wars. In monopolistic competition, highlight the role of branding and product differentiation.
• Evaluate the context: High competition lowers profit margins but drives innovation and efficiency. Low competition (monopoly) allows high profits but can lead to complacency and poor customer choice.
