Unit costs formula - reminder

Average cost per unit is calculated using this formula:

Total production costs in period (£)

Total output in period (units)

Q1 Q2

Unit costs are falling as output increases from Q1 to Q2

= economies of scale

Unit costs are falling as output increases from Q1 to Q2

= economies of scale

Unit costs start to rise as output rises above Q3

= diseconomies of scale

Unit costs start to rise as output rises above Q3

Minimum efficient scale

The level of output at which average

cost stops falling as output increases

Minimum efficient scale

The output at which average unit costs of

production are at their minimum

The output at which average unit costs of

production are at their minimum

Examples of Internal economies of scale

Buying economies

Buying in greater quantities usually results in a lower price (bulk-buying)

Technical Use of specialist equipment or processes to boost productivity

Marketing Spreading a fixed marketing spend over a larger range of products, markets and customers

Network Adding extra customers or users to a network that is already established (e.g. mobile phones)

Financial Larger firms benefit from access to more and cheaper finance

External economies of scale

Arise from the industry as a whole – i.e. all competitors benefit

Often associated with particular geographic areas E.g. Creative & media in London

Examples Having many specialist suppliers close by Access to research and development facilities Pool of skilled labour to choose from

It is still worth knowing about others to build out your answers and display your wider knowledge!

Examples of diseconomies of scale

Poor communication More difficult to control a larger, more

complex business More frequent machinery & employee

breakdown if output & capacity utilisation is too high

Loss of management focus

What about this for scale!
