Specialisation, the division of labour and money

Specialisation and the division of labour

Specialisation is when individuals, firms, regions or countries concentrate on producing a limited range of goods or services. The division of labour is specialisation by workers: production is split into separate tasks, each done by a different worker.

In *The Wealth of Nations* (1776), Adam Smith described a pin factory: a worker untrained in the trade 'certainly could not make twenty' pins a day, yet in a small factory where the work was divided into 'about eighteen distinct operations', ten men made 'upwards of forty-eight thousand pins in a day'. He argued that division of labour raises output because workers become more skilled at one task, no time is lost switching between tasks, and dividing work into simple tasks encourages the use of machinery.

Advantages and disadvantages

Advantages:

• higher productivity (output per worker), so lower average costs and possibly lower prices
• workers build skill and speed through repetition
• less time lost moving between tasks; training is quicker
• easier to use specialised machinery

Disadvantages:

• repetitive work causes boredom and low motivation, so quality may fall and absenteeism rise
• interdependence: if one stage stops (a strike, a supply delay), the whole process stops
• workers' skills are narrow, so structural unemployment is more likely if the job disappears
• loss of variety and craft skill; products may become standardised
• for countries, specialising in a few products makes them vulnerable to falls in world demand

Why specialisation needs money

Specialists must trade to get everything else they need. Without money, trade is by barter, which needs a double coincidence of wants (each side must want what the other has). Money removes this problem.

The four functions of money:

• Medium of exchange: accepted in payment for goods and services, so barter is not needed.
• Measure of value (unit of account): prices are expressed in one unit, so goods can be compared.
• Store of value: money keeps purchasing power over time (unless inflation is high), so income can be saved.
• Method of deferred payment: debts and contracts can be settled in future, allowing credit.

The medium of exchange function is the most important for specialisation, because it lets a specialist sell their output and buy anything else.

Worked example

A car factory moves from teams that each build a whole car to an assembly line where each worker fits one part. Explain one advantage for the firm.

1. Knowledge: the division of labour splits production into separate tasks.
2. Analysis: each worker repeats one task, becomes faster and more skilled, and no time is lost switching tools.
3. So output per worker rises and the average cost of each car falls.
4. Application: a car has thousands of parts, so time savings on each repeated task add up.

Answer: Higher labour productivity, lowering average costs per car.

Check yourself

1. In Adam Smith's pin factory example, output rose mainly because
   • production was divided into separate tasks done by different workers
   • workers were paid more
   • the factory used more land
   • pins were sold abroad
   Show answer

   production was divided into separate tasks done by different workers. Smith used the pin factory to show the gains from the division of labour.

2. Which is a disadvantage of the division of labour?
   • Workers become faster at their tasks
   • It is easier to use specialised machinery
   • A strike at one stage can halt the whole production line
   • Training each worker takes less time
   Show answer

   A strike at one stage can halt the whole production line. Specialised stages depend on each other: interdependence.

3. The main problem with barter that money solves is the need for
   • a double coincidence of wants
   • a store of value
   • government regulation
   • specialised machinery
   Show answer

   a double coincidence of wants. With barter, each trader must want exactly what the other offers.

4. Prices in a shop are all shown in dollars so that customers can compare items. Which function of money is this?
   • Store of value
   • Method of deferred payment
   • Medium of exchange
   • Unit of account (measure of value)
   Show answer

   Unit of account (measure of value). A common unit lets values be compared.

5. High inflation most directly damages which function of money?
   • Unit of account
   • Store of value
   • Medium of exchange
   • Double coincidence of wants
   Show answer

   Store of value. If prices rise quickly, money saved buys less in future.

6. A firm signs a contract to pay a supplier $50,000 in six months' time. Which function of money makes this possible?
   • Medium of exchange
   • Unit of account
   • Store of value
   • Method of deferred payment
   Show answer

   Method of deferred payment. Debts can be settled at a future date in money.

7. Explain one advantage of the division of labour for a clothing manufacturer.
   Show answer

   Each worker repeats one task such as cutting or stitching, so they become more skilled and faster and no time is lost switching tasks. Labour productivity rises, so the average cost of each garment falls.. Advantage, then a linked chain of reasoning, then the effect on costs or output.

8. In Smith's pin factory, ten men made about 48,000 pins a day. How many pins is that per worker per day?
   Show answer

   4800 pins. 48,000 / 10 = 4,800 pins per worker, compared with fewer than twenty for an untrained worker alone.
