The four factors of production are land, labour, capital, and entrepreneurship. They are the scarce resources used to produce goods and services, and they are studied in IB Economics subtopic 1.1, What is economics?, at both SL and HL.
How Each Factor Contributes to Production
Production normally requires a combination of all four factors. For example, a bakery needs a site and raw materials, workers, ovens, and an entrepreneur who organizes the business and accepts its risks.
| Factor of production | Precise meaning and examples | Associated income |
|---|---|---|
| Land | All natural resources used in production, including physical land, water, forests, minerals, sunlight, and agricultural resources. | Rent |
| Labour | Human physical and mental effort used in production, such as the work of builders, teachers, engineers, and managers. Its productivity can be improved through education, training, and healthcare. | Wages or salaries |
| Capital | Produced resources used to produce other goods and services, such as machinery, tools, factories, computers, and infrastructure. | Interest |
| Entrepreneurship | The organization of the other factors of production. Entrepreneurs make decisions, identify opportunities, innovate, and accept the risk that a business may fail. | Profit |
These factors are limited, so their use involves scarcity, choice, and opportunity cost. If land, workers, or machinery are allocated to producing one good, they cannot simultaneously be used to produce the next best alternative.
A common misconception is that capital means money. In economics, money is primarily a financial means of purchasing resources; physical capital refers to produced assets that increase productive capacity. Similarly, an entrepreneur is not simply a manager: entrepreneurship specifically involves organizing resources, making strategic decisions, and bearing risk.
Exam Technique
For a define question, give the precise economic meaning rather than only an example. If asked to explain, connect each factor to production and use a specific business example; do not confuse capital with money or land with only the physical site.
