Business Activity
Why businesses exist, what they produce, the resources they use, and the choices they must make — the foundation of everything in IGCSE Business Studies.
Needs, Wants & Scarcity
Why resources run out — and why that means every business and person must make choices.
Things essential for survival — food, water, shelter, clothing, basic healthcare.
Things we desire but can live without — a sports car, holidays, the latest phone. Wants are unlimited.
Unlimited wants + limited resources = the fundamental economic problem. Choices must be made.
A need is something you genuinely cannot survive without. A want is something you would like to have but can live without. The line between them is not always obvious — food is a need, but a five-course restaurant meal is a want. Basic clothing is a need; branded designer trainers are a want.
The critical business insight: wants are unlimited. No matter how wealthy a person becomes, they always want more or something different. This is why scarcity never disappears — not even in the richest economies.
📋 Real-life example
Think about how advertising works. Companies like Apple do not advertise that you need the latest iPhone — they create a want by showing you status, design and new features. This is the business response to unlimited wants: constantly creating new desires to drive demand.
Scarcity means that the resources available — land, workers, machinery, money — are all limited in supply. Yet the list of things people want has no end. This mismatch between unlimited wants and limited resources is called the economic problem.
It forces every individual, business, and government to make choices. Every choice has a cost — not always in money, but in what you had to give up. This is why economics matters to business: every decision about what to produce, how to produce it, and who to sell it to is shaped by scarcity.
The same item can be a need in one context and a want in another. In a rural area with no transport, a car might be a need to get to work. In a city with excellent public transport, a car is usually a want. In the IGCSE exam, always justify your classification — don’t just state it.
- Drinking water → Need (essential for survival)
- A bottled sparkling water at a café → Want (tap water would do)
- Basic medication → Need (health essential)
- Cosmetic surgery → Want (not essential for survival)

📌 Exam tip
In the exam, always justify your need/want classification with a reason. “A car is a want because public transport is available as an alternative” scores more than just “a car is a want.”
The Factors of Production
Every business needs resources to produce — here are the four types, what they are, and what their owners earn.
The resources businesses combine to produce goods and services. Without them, nothing can be made.
They are all scarce. This forces businesses to combine them efficiently and make trade-off decisions.
L–L–C–E — Land, Labour, Capital, Enterprise. Each earns a different financial reward.
🧠 Memory hook — L·L·C·E
Land means all natural resources — not just physical ground, but everything found in, on or from the earth. It includes the climate and physical environment too.
- Agricultural land and soil for farming
- Oil, gas, coal and mineral deposits
- Rivers, lakes, seas and fishing waters
- Forests and timber
- Wind, sunlight and water for renewable energy
💰 Reward paid to Land = Rent
Owners of land (farmers, landlords, mining companies) earn rent for allowing their natural resource to be used in production.
Labour is all human effort — both physical and mental — used in production. The quality of labour (called human capital) depends on education, training, skills and experience.
- Factory workers assembling products on a line
- Teachers delivering lessons to students
- Software engineers building apps and systems
- Managers making strategic decisions
- Doctors, nurses, surgeons providing healthcare
💰 Reward paid to Labour = Wages / Salary
Workers earn wages (paid hourly or weekly) or salaries (annual fixed pay) for their contribution to production.
Capital means man-made resources used to produce other goods and services. This is NOT money — capital refers to the physical assets that money has been used to buy.
- Machinery and factory equipment
- Computers, servers and technology systems
- Warehouses, factories and office buildings
- Delivery vehicles and transport fleets
- Roads, railways, airports and ports (infrastructure)
⚠️ Common exam mistake
Capital does NOT mean money. Money is used to buy capital, but money itself is not a factor of production. If asked “give an example of capital used by a bakery,” the correct answer is ovens and mixing machines — not “the baker’s savings.”
💰 Reward paid to Capital = Interest
Those who lend money to buy capital equipment earn interest. The business pays interest on loans used to fund capital investment.
Enterprise is the human skill of organising the other three factors of production — land, labour and capital — and taking the financial risk of starting and running a business. Without enterprise, the other factors sit unused.
- Starting a new business using personal savings
- Identifying a gap in the market others have missed
- Developing a new product or service idea
- Taking the risk that the business might fail and money could be lost
- Making key decisions about what to produce and how
📋 Example — the entrepreneur
When Amara left her job to open a café, she used her savings (risk), rented premises (land), hired staff (labour) and bought coffee machines (capital). Her willingness to organise and risk all this is enterprise. If the café succeeds, she earns profit. If it fails, she loses her savings — this is the entrepreneurial risk.
💰 Reward paid to Enterprise = Profit
Entrepreneurs earn profit as reward for taking the risk. If the business fails, they may earn nothing — or lose their investment entirely.
| Factor | What it includes | Example | Reward |
|---|---|---|---|
| Land | All natural resources | Oil field, farmland, river | Rent |
| Labour | Human physical & mental effort | Factory worker, teacher, manager | Wages / Salary |
| Capital | Man-made production assets (NOT money) | Machinery, buildings, vehicles | Interest |
| Enterprise | Risk-taking & organising the other factors | Starting a business, innovating | Profit |
Opportunity Cost
Every choice has a cost — not just in money, but in what you had to give up to make that choice.
The next best alternative forgone when a decision is made. Not just any alternative — the best one you gave up.
Because resources are scarce, choosing one use for them automatically means you cannot use them for something else.
Individuals, businesses and governments all face opportunity costs with every decision they make.
The phrase “next best alternative forgone” sounds technical, but the idea is simple: whenever you choose to do or buy something, you automatically cannot do or buy something else with the same resources. Opportunity cost is the value of that second choice you had to sacrifice.
Crucially, it is not just any alternative you gave up — it is the specific best one. If you had five options and chose option 1, the opportunity cost is option 2 (the second-best), not options 3, 4 or 5.
Imagine you have $5,000 saved. You are choosing between:
- Option A: Buy a used car
- Option B: Go on a holiday (your next favourite option)
- Option C: Put it in a savings account
You choose Option A — buy the car. The opportunity cost is Option B — the holiday you gave up. Option C is not the opportunity cost because it was not your next best choice.
Key exam technique
Always name the specific alternative in your exam answer. Writing “the opportunity cost is the holiday” scores marks. Writing “something was given up” does not.
Businesses face opportunity costs constantly. Every dollar spent on one thing cannot be spent on another.
| Decision | Opportunity Cost |
|---|---|
| Buy new machinery ($200k) | The staff training programme that money could have funded |
| Open a new branch in City A | The branch in City B that was the next-best location choice |
| Use land to build a factory | The offices or car park that land could have been used for |
| Spend 6 months developing Product X | The time that could have been spent improving Product Y |
Governments face the biggest opportunity costs of all because they control enormous budgets. Every policy decision means other priorities go unfunded.
📋 Example
A government has $500 million in its budget. It decides to build a new hospital. The opportunity cost is the 200 km of new motorway that the same money could have built — because that was the next-best spending option. Not the school, not the park — specifically the motorway.

Scenario: Layla has Saturday free. She can study for exams, earn $60 working a shift, or spend the day with friends. She chooses to study. What is her opportunity cost?
📌 Exam tip — how to structure an opportunity cost answer
“The opportunity cost of [decision] is [specific next best alternative] because [reason it was the next-best option].”
Example: “The opportunity cost of building the hospital is the motorway, because that was the government’s next-best spending priority with the same $500m budget.”
The Purpose of Business Activity
What businesses actually do — combining resources to produce goods and services that create value for people.
Combining factors of production to produce goods or services that satisfy human needs and wants.
The difference between selling price and input costs. Businesses compete to maximise this.
Added Value = Selling Price − Cost of Inputs
Businesses exist to solve a problem: people have needs and wants, but resources are scarce. By combining land, labour, capital and enterprise, businesses produce outputs — goods and services — that people are willing to pay for. In doing so, they also create jobs, generate income and add value to raw materials.
| Goods (tangible) | Services (intangible) | |
|---|---|---|
| What is it? | A physical product you can touch and own | A non-physical activity you experience |
| Can it be stored? | Yes — produced now, sold later | No — consumed as it is produced |
| Examples | Car, bread, phone, furniture | Haircut, banking, education, transport |
| Sector | Mainly primary & secondary | Tertiary sector |
Added value is not just about profit — it explains why a customer pays more for a branded product than a generic one. A cup of coffee costs about 30p in ingredients. Starbucks charges $6. The $5.70 difference is the added value created by location, atmosphere, branding, training and service.
Businesses add value through:
- Design: Making a product more attractive or functional
- Branding: Creating perceived quality and trust (Apple, Nike, Louis Vuitton)
- Convenience: Delivering to the door, opening 24 hours
- Quality: Using better materials or more skilled workers
- Customer service: Making the experience enjoyable and reliable
📋 Example — added value in action
A bakery buys flour, butter and eggs for $1.20 per loaf. It bakes, packages and delivers to a supermarket, which sells the loaf for $3.50. The bakery’s added value = $3.50 − $1.20 = $2.30 per loaf. That $2.30 covers the bakery’s labour, energy, packaging and profit.
While profit is the primary aim of most private-sector businesses, business activity also delivers broader economic benefits:
- Employment: Businesses hire workers, creating incomes that fund consumption
- Choice: Competition between businesses gives consumers options on price and quality
- Innovation: The profit motive drives businesses to create new products and improve processes
- Tax revenue: Businesses pay taxes that fund schools, hospitals and infrastructure
- Satisfying wants: The whole economy depends on businesses converting resources into things people actually want

📌 Exam tip
When asked to calculate added value, be careful: it is selling price minus cost of bought-in inputs — not profit. Added value still needs to cover wages, overheads and other costs before profit is calculated.
