2. Factors of Production
2.1 The Four Primary Factors
- Land – all natural resources (soil, minerals, forests, climate, water).
- Labour – human effort, both physical and mental, used in production.
- Capital – man‑made inputs that assist production. It is divided into:
- Physical capital – machinery, equipment, buildings, infrastructure.
- Human capital – education, skills, health, training of the workforce.
- Enterprise (Entrepreneurship) – the ability to combine the other three factors, take risks and innovate.
2.2 Factor‑Payments (Rewards)
| Factor |
Typical Reward |
| Land |
Rent |
| Labour |
Wages (including salaries, commissions, overtime) |
| Physical Capital |
Interest (or profit on capital equipment) |
| Human Capital |
Higher wages, bonuses, training allowances |
| Enterprise |
Profit (normal & super‑normal), entrepreneur’s income |
2.3 The Role of the Entrepreneur
- Identifies market opportunities and unmet consumer needs.
- Organises and coordinates land, labour and capital to create a production process.
- Assumes risk – financial (investment loss) and operational (technology failure).
- Drives innovation – introduces new products, processes or organisational methods.
- Responds to price signals and profit incentives, ensuring efficient resource allocation.
3. Division of Labour
3.1 Definition
Division of labour is the splitting of a production process into a series of distinct, repetitive tasks, each performed by a different worker or group of workers.
3.2 How It Increases the Marginal Product of Labour (MPL)
- Specialised workers acquire skill faster → higher MPL (MPL = ΔQ / ΔL).
- Reduced set‑up and transition time between tasks lowers the marginal cost of each unit.
- At the margin, firms compare the extra output from further specialisation with the extra coordination cost.
3.3 Short‑Run vs Long‑Run Gains
- Short‑run: Immediate productivity boost from skill acquisition and time‑saving.
- Long‑run: Enables investment in specialised machinery, larger scale production and economies of scale.
3.4 Benefits
- Higher productivity – workers become experts in a narrow task.
- Lower transition (setup) time between tasks.
- Facilitates the use of specialised machinery for each task.
- Supports economies of scale as output expands.
- Improves productive efficiency – more output is produced with the same resources.
3.5 Costs / Limitations
- Monotony can reduce worker motivation and increase turnover.
- Over‑specialisation makes the system vulnerable to disruptions (e.g., absenteeism, machine breakdown).
- Requires a sufficiently large market to absorb the higher output; otherwise excess supply may arise.
- May lead to allocative inefficiency if the tasks chosen do not reflect consumer preferences.
- Government regulation (health & safety, labour standards) can increase costs.
3.6 Illustrative Example – Adam Smith’s Pin Factory
Smith observed a pin factory where ten workers each performed a single step (drawing wire, straightening, cutting, etc.). Output rose from 20 pins per day (when each worker did all tasks) to 48 000 pins per day – a clear demonstration of the marginal productivity gain from division of labour.
3.7 Diagrammatic Guidance
Suggested diagram: Two‑stage production line.
- X‑axis: Labour (number of workers).
- Y‑axis: Output.
- Curve A: “No division” – shallow slope.
- Curve B: “Division of labour” – steeper slope, showing higher MPL.
Label the marginal product at a few points to illustrate the short‑run increase.
4. Specialisation
4.1 Definition
Specialisation occurs when individuals, firms or countries concentrate on producing a narrow range of goods or services in which they have a comparative advantage.
4.2 Relationship to Division of Labour
- Division of labour is the micro‑level mechanism that makes specialisation possible within a firm or industry.
- Specialisation decides what is produced; division of labour decides how it is produced.
4.3 Comparative Advantage & Gains from Trade
When each country (or firm) produces the good with the lower opportunity cost, total world output rises and both parties can consume beyond their own production‑possibility frontiers (PPFs).
Key Formulae
- Opportunity Cost of X in terms of Y = ΔY / ΔX
- Comparative Advantage → lower opportunity cost.
Illustrative Calculation
| Country |
Wheat (units) |
Cloth (units) |
| A |
100 |
50 |
| B |
80 |
80 |
Opportunity cost of 1 unit of cloth:
- Country A: 2 units of wheat** (100 / 50)
- Country B: 1 unit of wheat** (80 / 80)
→ Country B has the comparative advantage in cloth; Country A in wheat. By specialising and trading, both can achieve consumption bundles outside their individual PPFs, illustrating gains from specialisation.
4.4 Economic Gains from Specialisation
- Productive efficiency – resources are used where they have the lowest marginal cost.
- Allocative efficiency – output composition moves closer to consumer preferences.
- Higher total output and lower average costs (economies of scale).
- Facilitates innovation as firms focus on core competencies.
4.5 Limitations of Specialisation
- Exposure to external shocks (global demand swings, supply‑chain disruptions).
- Loss of flexibility – switching production to a different good can be costly.
- Risk of structural unemployment if workers’ skills become obsolete.
- Potential increase in income inequality if gains are not evenly distributed.
- Government may intervene through tariffs, subsidies, retraining programmes or industrial policy to mitigate adverse effects.
4.6 Diagrammatic Guidance
Suggested diagram: Two‑country PPFs with autarky points (A₁, B₁), specialised production points (A₂, B₂), and post‑trade consumption points (C₁, C₂) lying outside each country’s PPF.
- Show slopes (opportunity costs).
- Draw a straight line representing the terms of trade (TOT) that lies between the two slopes.
- Highlight the gain in consumption for each country.
5. Integration with Core Economic Concepts
- Scarcity & Choice: Limited resources force producers to decide which tasks to specialise in and which goods to produce.
- The Margin: Firms compare the marginal gain from further division of labour or specialisation with the marginal cost (e.g., coordination, training).
- Time: Short‑run gains arise from skill acquisition; long‑run gains from capital investment and economies of scale.
- Efficiency: Division of labour improves productive efficiency; specialisation improves both productive and allocative efficiency.
- Role of Government: May regulate working conditions, provide education (human capital), subsidise R&D, or intervene in trade to correct market failures arising from over‑specialisation.
6. Summary Points
- Factors of production – land, labour, capital (physical + human) and enterprise – each earn a distinct factor‑payment.
- Division of labour breaks a process into repetitive tasks, raising marginal product, reducing transition time and enabling specialised equipment.
- Specialisation is the strategic decision to focus on the good or service with the lowest opportunity cost (comparative advantage).
- Both concepts generate productivity gains, economies of scale and higher efficiency, but they also create monotony, vulnerability to shocks and possible distributional issues.
- Government can influence outcomes through education, health, labour standards and trade policy.
7. Sample Examination Questions (AS/A‑Level)
- Explain how division of labour can increase the marginal product of labour. Use a short diagram to illustrate the short‑run and long‑run effects.
- Using the data in the table below, calculate the opportunity cost of cloth for each country and recommend which good each should specialise in. Explain how trade would allow both countries to achieve a higher level of consumption.
| Country |
Wheat (units) |
Cloth (units) |

- Discuss two limitations of division of labour and two limitations of specialisation. In your answer, refer to monotony, vulnerability to disruption, structural unemployment and the possible role of government.
- Explain the difference between physical capital and human capital. How does each contribute to the productivity of labour?
