Economies of Scale
• The advantages of large scale
production that result in lower unit
(average) costs (cost per unit)
• AC = TC / Q
• Economies of scale – spreads total
costs over a greater range of
output

• Reputation
• Local knowledge and skills
• Infrastructure
• Training facilities

Economies of Scale
• Internal: Technical
– Specialisation – large organisations
can employ specialised labour
– Indivisibility of plant – machines can’t be
broken down to do smaller jobs!
– Principle of multiples – firms using more
than one machine of different capacities -
more efficient
– Increased dimensions – bigger containers
can reduce average cost

Economies of Scale
• Commercial
• Large firms can negotiate
favourable prices as a result
of buying in bulk
• Large firms may have advantages
in keeping prices higher because
of their market power
http://www.bized.co.uk
Copyright 2006 – Biz/ed
Economies of Scale
• Financial
• Large firms able to negotiate
cheaper finance deals
• Large firms able to be more

merchant banks to arrange finance
http://www.bized.co.uk
Copyright 2006 – Biz/ed

–R&D
http://www.bized.co.uk
Copyright 2006 – Biz/ed
Economies of Scale
Minimum Efficient Scale – the point
at which the increase in the scale of production
yields no significant unit cost benefits
Minimum Efficient Plant Size – the
point where increasing the scale of production of an
individual plant within the industry yields
no significant unit cost benefits
http://www.bized.co.uk
Copyright 2006 – Biz/ed
Diseconomies of Scale
• The disadvantages of large scale
production that can lead to
increasing average costs
– Problems of management
