What this dot point is asking
The syllabus wants you to identify the four factors of production, describe what each one contributes to making goods and services, and link each factor to the reward it earns. The big idea is that all production uses up scarce resources, and economists sort those resources into four groups so that we can analyse them clearly.
The answer
Why we group resources into four factors
Producing any good or service uses resources. To make analysis manageable, economists group all the world's resources into four types, called the factors of production. Every input to production is one of these four, and all four are scarce, which is why producing more of one good means using resources that could have made something else.
Land
Land is the gift of nature. Examples are the soil a farmer plants in, the iron ore a miner digs up, and the sea a fishing firm fishes. The reward earned by land is rent.
Labour
The quality of labour can be raised by education, training and better health, which is called investment in human capital. The reward earned by labour is wages (or salaries).
Capital
Examples are machines, tools, factories, computers and delivery vans. Note that to an economist money is not capital; money only buys capital. The reward earned by capital is interest.
Enterprise
The entrepreneur decides what to produce, combines land, labour and capital, and takes the risk that the business may fail. The reward earned by enterprise is profit, which is what is left after all other costs are paid.
Examples in context
Example 1. A Singapore hawker stall. The stall uses land (the site and the ingredients grown elsewhere), labour (the hawker cooking and serving), capital (the wok, stove and counter), and enterprise (the hawker who set up and runs the stall and takes the risk). Every small business combines all four factors.
Example 2. Investing in human capital. Singapore spends heavily on education and skills programmes such as SkillsFuture. This raises the quality of labour, so the same number of workers can produce more. Improving a factor of production, not just adding more of it, is a key way an economy grows.
Try this
Cue. State the reward earned by each of the four factors of production. Land earns rent, labour earns wages, capital earns interest, and enterprise earns profit.
Cue. Explain why money is not classed as capital. Capital is the manufactured goods used to produce other goods, such as machines and tools. Money is only a means of buying capital, so it is not itself a factor of production.
Cue. Give one example each of land, labour and capital used by a hospital. Land: the site and the natural resources behind its supplies. Labour: the doctors and nurses. Capital: the scanners, beds and the building.

Original4 marksIdentify the four factors of production and state the reward earned by each.Show worked answer →
A 4 mark question rewards the four factors named correctly, each paired with its reward.
The four factors of production and their rewards are:
- Land, which earns rent.
- Labour, which earns wages.
- Capital, which earns interest.
- Enterprise, which earns profit.
Markers reward all four factors named and each matched to the correct reward. A common slip is to pair capital with profit; capital earns interest, while profit is the reward for enterprise.
Original6 marksUsing examples from a bakery, explain how three different factors of production are combined to produce bread.Show worked answer →
A 6 mark explain question rewards three factors, each defined briefly and applied to the bakery.
- Land
- Land is the natural resources used in production. For the bakery, this includes the wheat grown on farmland and the site the shop stands on.
- Labour
- Labour is the human effort, both physical and mental, used in production. For the bakery, this is the bakers who mix and bake and the staff who serve customers.
- Capital
- Capital is the manufactured aids to production. For the bakery, this is the ovens, mixers and the building itself.
A full answer would add enterprise, the owner who organises the land, labour and capital and takes the risk of running the bakery.
Markers reward each factor correctly defined and clearly applied to a specific resource in the bakery, not just named.
