1. Needs, wants and scarcity

A need is something a person must have to live, such as food or shelter. A want is something a person would like but can live without. People's wants have no limit.

Resources are limited. This is scarcity: there are never enough resources to satisfy every want.

For a business, scarcity means limited money, materials and time. The business cannot do everything, so it must choose how to use what it has.

Worked example 14 marks

Tolu runs a small bakery called Tolu's Loaves. She sells bread and cakes. After a poor harvest she can buy only half her usual amount of flour. Outline two ways scarcity affects Tolu's Loaves.

  1. 1

    Knowledge: the business cannot produce everything its customers want. [1]

  2. 2

    Application: with half her usual flour, Tolu bakes fewer loaves than customers ask for. [1]

  3. 3

    Knowledge: the business must choose how to use its limited resources. [1]

  4. 4

    Application: Tolu has to decide how much flour goes into bread and how much into cakes. [1]

2. Opportunity cost

Scarcity forces a choice, and every choice gives something up. The opportunity cost of a choice is the next best alternative given up.

Opportunity cost is not the money spent. It is the benefit lost by choosing one option instead of another. Name the one alternative that was given up, not every alternative.

An owner who puts savings into the business faces it too. The opportunity cost is whatever else the savings would have paid for.

Examiner insight

“The best answers made good use of the information provided and explained how a new business may find it difficult to obtain bank loans or considered the opportunity cost for an owner of using their own savings.”

Worked example 12 marks

Nadia owns Bright Spark, an electrical repair shop. She has £8,000 to spend. She can buy a new van or new tools, but not both. She chooses the van. Explain what is meant by opportunity cost, using Nadia's choice.

  1. 1

    Knowledge: opportunity cost is the next best alternative given up when a choice is made. [1]

  2. 2

    Application: Nadia's opportunity cost is the new tools she did not buy. [1]

3. Specialisation

Specialisation is when workers focus on one task. They build a higher level of skill at that task. A definition needs both parts: the focus and the higher skill.

The benefits are higher output, fewer mistakes, better quality and time saved. Develop each one: skilled workers finish each item faster, so the labour cost of each unit falls. An effect on sales or reputation is not an advantage of specialisation.

The main drawback is boredom from repeating the same task. Division of labour is a different term: it is the splitting of a job into separate tasks.

Examiner insight

“Weaker responses lost marks by confusing specialisation with division of labour.” “A common mistake was to repeat the same point for both benefits using different words. References to the effect on sales or reputation could not be credited as these are not advantages of specialisation.”

Worked example 16 marks

Mei Foods makes ready meals. Each worker on the line does one task only, such as making the sauce or filling the trays. Explain two advantages to Mei Foods of using specialisation.

  1. 1

    Knowledge: workers build a higher level of skill, so they work faster. [1]

  2. 2

    Application: a worker who only makes the sauce becomes quick at making it. [1]

  3. 3

    Analysis: more meals are made in each hour, so the labour cost of each meal falls. [1]

  4. 4

    Knowledge: workers make fewer mistakes. [1]

  5. 5

    Application: a worker who only fills trays puts the right portion in each one. [1]

  6. 6

    Analysis: less food is wasted, so the cost of ingredients for each meal falls. [1]

4. Purpose of business activity

A business exists to produce goods or services that satisfy customers' needs and wants. In doing this a business adds value: it sells its product for more than the bought-in materials cost.

Link the purpose to the business in the question. A salon exists to satisfy customers who want a haircut. Two purposes must be two different ideas, not one idea in different words.

Worked example 14 marks

Kwame has opened Fresh Cuts, a salon in his home town. He buys shampoo and hair dye from a wholesaler. Outline two purposes of Kwame's business activity.

  1. 1

    Knowledge: to provide a service that satisfies customers' wants. [1]

  2. 2

    Application: people in Kwame's town want haircuts, and Fresh Cuts provides them. [1]

  3. 3

    Knowledge: to add value. [1]

  4. 4

    Application: Kwame charges more for a hair colour than the shampoo and dye cost him. [1]

5. Added value

Added value is the difference between the selling price and the cost of bought-in materials. A business buys inputs, changes them and sells the result for more.

It is not the same as profit. Wages, rent and machinery are costs of production, not bought-in materials, so they are not subtracted. The business pays those costs out of its added value, and what is left is profit.

A definition must explain the term. Repeating that the business "adds value", or listing ways to increase it, earns nothing.

Examiner insight

“Common errors were to repeat the words ‘add or increases value’ rather than explain the term.” “Most candidates understood that added value is linked to selling price but were unable to explain how this related to the cost of raw materials.”

Worked example 12 marks

Oakline Furniture buys wood costing £60 for each table. It pays £40 in wages for each table. It sells the table for £150. Define added value.

  1. 1

    Knowledge: the difference between the selling price of a product [1]

  2. 2

    Knowledge: and the cost of its bought-in materials. [1]

  3. 3

    For Oakline this is £150 − £60 = £90 on each table. The £40 of wages is paid out of the £90.

6. Increasing added value

There are two routes. A business can increase the selling price or reduce the cost of bought-in materials. Cutting wages or machinery costs is not a route: those are not bought-in materials.

A higher price needs a reason, such as better quality, packaging or service. Customers who see higher perceived quality will accept it. Cheaper materials come from a cheaper supplier.

Explain each route as a chain that ends at the price or the material cost. New packaging that only "attracts more customers" earns nothing. In a question that asks for a recommendation, weigh the risk too: a higher price can lose sales.

Examiner insight

“The best responses explained that changing packaging would improve perceived quality allowing a higher price to be charged therefore increasing the profit margin on each drink.” “Even the strongest candidates struggled to develop their answers fully to gain both analysis marks as they could not explain how their chosen way would increase value added.”

Worked example 16 marks

Delta Juice makes fruit drinks and sells them in plastic bottles to cafés. Explain two ways Delta Juice could increase its added value.

  1. 1

    Knowledge: increase the selling price. [1]

  2. 2

    Application: Delta Juice could move from plastic to glass bottles. [1]

  3. 3

    Analysis: cafés see higher quality and pay more for each bottle, so the gap between price and material cost widens. [1]

  4. 4

    Knowledge: reduce the cost of bought-in materials. [1]

  5. 5

    Application: Delta Juice could buy its fruit from a cheaper supplier. [1]

  6. 6

    Analysis: the materials in each drink cost less while the price stays the same, so added value on each drink rises. [1]

Recap

  • Needs must be met; wants are unlimited; resources are limited. This is scarcity.
  • Opportunity cost = the next best alternative given up.
  • Specialisation = workers focus on one task and build a higher level of skill.
  • A business exists to produce goods or services that satisfy needs and wants, and it adds value in doing so.
  • Added value = selling price minus cost of bought-in materials. It is not profit, and wages are not subtracted.
  • Raise added value by raising the price or cutting the cost of bought-in materials, and explain the chain.

  10. Harbour Kayaks has 5 workers who build 20 kayaks a month by hand. Each kayak sells for £900 and uses £400 of bought-in materials. Rival builders charge £850. The owner wants to increase added value. Option 1: specialisation. Each worker does one stage only. The owner expects fewer mistakes, so less material is wasted and bought-in materials fall to £360 a kayak. Option 2: a hand-painted finish. Bought-in materials rise to £440 a kayak and the price rises to £1,000. Consider both options and recommend which one the owner should choose. Justify your answer.12 marks
