Classify factors of production and their rewards
Identify land, labour, capital and enterprise, then explain how their quantity and quality can change.
Cambridge IGCSE Economics 0455 / IGCSE (9–1) Economics 0987, 2027–2029 Version 1. Apply each model to the stated evidence and qualify conclusions where effects depend on context. Practice is original and self-checked; it is not a Cambridge paper, mark scheme or official grade.
Before you begin
- No prior economics study is assumed. Read the scenario for the decision-maker, the market or economy involved, the time period and the evidence supplied.
Work on paper. Try each question before revealing help, and explain why your method works.

What is the usual reward to labour?
What you will learn
- Define the four factors of production
- Match each factor with its reward
- Explain changes in factor quantity and quality
Four inputs, four common rewards
Land means natural resources; labour is human physical or mental effort; capital is man-made equipment used to produce other output; enterprise organises the other factors and accepts business risk. Their common rewards are rent, wages, interest and profit respectively.
Capital in economics means productive equipment, not simply money. A loan may finance a machine, but cash itself is not the machine used in production.
Quantity and quality both matter
The quantity of labour can change with population or participation; its quality can change with education, training and health. Investment can add capital, while maintenance or new technology can change its quality.
Resources can become more productive without increasing in number. Explain the mechanism and avoid treating a possible change as guaranteed output growth.
Pause and explain
A firm trains existing staff and buys updated equipment. What might change?
Worked example
A farm hires trained workers, rents land, buys a tractor and is organised by an owner who risks savings. Classify the four factors and rewards.
Show the worked solution
- Land is the natural resource; labour is workers' effort.
- The tractor is capital; organising and bearing risk is enterprise.
- Match rent, wages, interest and profit to the factors.
Answer Land earns rent, labour earns wages, capital earns interest and enterprise earns profit. The tractor is capital; the owner's organising role is enterprise.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A clinic uses a building, nurses, diagnostic machines and a director who organises services. Classify each factor.
Give me a hint
Classify each input by its economic role.
Compare my reasoning
- Building is a man-made productive asset.
- Nurses provide human effort.
- Machines are capital; the director's organising role is enterprise.
Building and diagnostic machines are capital; nurses are labour; the director supplies enterprise. Any natural resources used would be land.
Look for these in your work
- Capital identified
- Labour identified
- Enterprise identified
A training programme raises the number of qualified workers but some new jobs remain unfilled. Explain why labour quantity and quality do not guarantee more output.
Give me a hint
Consider job matching, other factors and effective demand.
Compare my reasoning
- Training may raise skills.
- Workers must match vacancies and have complementary equipment.
- Firms also need demand and other inputs to use the added capacity.
Training can improve labour quality, but output may not rise if skills do not match vacancies, equipment is lacking or firms lack demand. The effect depends on complementary resources.
Look for these in your work
- Quality improvement named
- Complementarity considered
- Demand or matching qualified
A manufacturer installs a faster machine but has no trained operator. Explain the production constraint.
Give me a hint
Connect capital quality to labour skills and use.
Compare my reasoning
- The machine may increase potential capacity.
- An untrained operator may be unable to use it safely or effectively.
- Training or support is needed before the productivity gain is realised.
The upgraded capital may have greater potential output, but without relevant labour skills the firm may not use it effectively. Complementary training is needed.
Look for these in your work
- Potential distinguished from realised output
- Labour complement explained
- Action supported
Common mistakes
- Calling money capital in the same sense as a productive machine
- Confusing enterprise with all paid work
- Assuming training increases productivity without considering relevance or access

Land earns rent
Rent is the common reward to the factor land.
