IGCSE Business Studies: Marketing (Cambridge 0450)

This guide covers Topic 3 Marketing, for Cambridge IGCSE Business Studies 0450, 2026 series (Version 2 — no significant changes affecting teaching from the prior version). Business Studies at 0450 is not tiered: all candidates study the same content, assessed across Paper 1 (Short Answer and Data Response) and Paper 2 (Case Study), each worth 50% of the final grade.

Where this fits in 0450

Marketing is the third of six topics in 0450, following Understanding business activity and People in business, and preceding Operations management, Financial information and decisions, and External influences on business activity. It is built around four sub-topics: marketing, competition and the customer; market research; the marketing mix; and marketing strategy.

3.1 Marketing, competition and the customer

This sub-topic sets out why marketing exists before looking at how it is done. The role of marketing is to identify customer needs, satisfy those needs, maintain customer loyalty and build customer relationships. Candidates need to understand why customer spending patterns change, why some markets become more competitive over time, and how businesses respond to both.

Two core distinctions are examined here:

• Niche marketing vs mass marketing — the benefits and limitations of targeting a small, specific segment of the market (niche) versus targeting the whole market with a single offer (mass). Niche marketing typically allows a business to charge premium prices and face less direct competition, but limits the size of the potential customer base; mass marketing can achieve economies of scale but faces more direct competitors.
• Market segmentation — dividing the market into groups of customers with similar characteristics, for example by age, socio-economic grouping, location or gender, and the benefits this brings to a business (more targeted promotion, product development that better matches customer needs). Exam questions frequently ask you to recommend and justify an appropriate method of segmentation for a given business scenario.

3.2 Market research

Market research is the process by which businesses gather information about their customers and markets before making decisions. The syllabus requires you to know:

• Primary research (original research carried out directly by or for the business): postal questionnaires, online surveys, interviews and focus groups, along with the benefits and limitations of each method.
• Secondary research (using information already collected by someone else): online sources, government statistics and paid commercial market research reports.
• The need for sampling — since it is rarely practical to survey an entire target market, and the factors that influence how accurate market research data actually is.
• Presenting and using market research results — analysing data shown as graphs, charts and diagrams, and drawing simple conclusions from it.

A common exam skill tested here is evaluation: weighing the cost and reliability of primary research against the speed and lower cost of secondary research for a specific business situation, rather than treating one as universally “better.”

3.3 Marketing mix

The marketing mix – the four Ps – is the centrepiece of this topic and the most heavily examined sub-topic in Marketing.

• Product: the benefits and limitations of developing new products, the role of brand image and packaging, and the product life cycle – its main stages (introduction, growth, maturity, decline) and extension strategies. You are expected to be able to draw and interpret a product life cycle diagram, and to explain how its stages influence other marketing decisions such as promotion and pricing.
• Price: pricing methods – cost-plus, competitive, penetration, skimming and promotional pricing – with their respective benefits and limitations, and the significance of price elasticity of demand (understanding the difference between elastic and inelastic demand and why it matters for pricing decisions; the syllabus explicitly states the PED formula and calculations are not assessed).
• Place: distribution channels, including the advantages and disadvantages of selling through wholesalers, retailers or directly to consumers.
• Promotion: the aims of promotion, different forms it can take (advertising, sales promotion), and the need for cost-effectiveness when spending a marketing budget.
• Technology and the marketing mix: the concept of e-commerce, its opportunities and threats for businesses and consumers, and the use of the internet and social media for promotion.

Because each of the four Ps interacts with the others (for example, a premium pricing strategy usually requires a matching product and promotion strategy), exam questions often ask you to evaluate how elements of the mix work together for a given business, not just define each P in isolation.

3.4 Marketing strategy

The final sub-topic asks you to bring the marketing mix together into a coherent strategy, and covers two further areas:

• Legal controls related to marketing — the impact of legal restrictions on marketing strategy, such as rules against misleading promotion and against selling faulty or dangerous goods.
• Entering new foreign markets — the growth potential of overseas markets, the problems of entering them (cultural differences, lack of local knowledge), and methods used to overcome these problems, such as joint ventures and licensing.

Questions on marketing strategy typically present a business scenario and ask you to recommend and justify which elements of the marketing mix should be prioritised, drawing on everything covered across 3.1 to 3.4 rather than 3.4 alone.

How to approach it

Marketing is one of the more scenario-driven topics in 0450: both papers are built around applying knowledge to a specific business context (Paper 1’s stimulus material, Paper 2’s case study), so practise linking marketing mix decisions back to the type of business and market segment described in each question, rather than writing generic definitions. The product life cycle and pricing methods are the two areas most consistently tested across past papers, so make sure you can both draw and interpret a life cycle diagram and justify a pricing method against the specific circumstances given, since “recommend and justify” questions carry Analysis and Evaluation marks (AO3 and AO4) that are not available from definitions alone.
