Economies of Scale

The advantages of large scaleproduction that result in lower unit(average) costs (cost per unit)

AC = TC / Q

Economies of scale spreads total

costs over a greater range ofoutput

Economies of Scale

External economies of scale theadvantages firms can gain as a result

of the growth of the industry normallyassociated with a particular area

Supply of skilled labour

Reputation

Local knowledge and skills Infrastructure

Training facilities

Economies of ScaleCapital Land Labour Output TC AC

Scale A 5 3 4 100

Scale B 10 6 8 300

Assume each unit of capital = 5, Land = 8and Labour = 2

Calculate TC and then AC for the two differentscales (sizes) of production facilityWhat happens and why?

Economies of ScaleCapital Land Labour Output TC AC

Scale A 5 3 4 100 57 0.57

Scale B 10 6 8 300 164 0.54

Doubling the scale of production (a rise of 100%) has ledto an increase in output of 200% - therefore cost of

productionPER UNIT has fallenDont get confused between Total Cost and Average CostOverall costs will rise but unit costs can fallWhy?

Economies of Scale

Internal: Technical

Specialisation large organisations

can employ specialised labour Indivisibility of plant machines cant be

broken down to do smaller jobs!

Principle of multiples firms using more

than one machine of different capacities -more efficient

Increased dimensions bigger containerscan reduce average cost


8/15



Economies of Scale

Indivisibility of Plant:

Not viable to produce productslike oil, chemicals on small scale need large amounts of capital

Agriculture machinery

appropriate for large scale work combines, etc.


9/15



Economies of Scale

Principle of Multiples:

Some production processesneed more than one machine

Different capacities

May need more than one machineto be fully efficient


10/15



Economies of Scale

Commercial

Large firms can negotiatefavourable prices as a resultof buying in bulk

Large firms may have advantages

in keeping prices higher becauseof their market power


11/15



Economies of Scale

Financial

Large firms able to negotiatecheaper finance deals

Large firms able to be moreflexible about finance shareoptions, rights issues, etc.

Large firms able to utilise skills ofmerchant banks to arrange finance


12/15



Economies of Scale

Managerial

Use of specialists accountants, marketing,lawyers, production, human

resources, etc.


13/15



Economies of Scale

Risk Bearing

DiversificationMarkets across regions/countries

Product ranges

R&D


14/15



Economies of Scale

Minimum Efficient Scale the pointat which the increase in the scale of productionyields no significant unit cost benefits

Minimum Efficient Plant Size the

point where increasing the scale of production ofan individual plant within the industry yieldsno significant unit cost benefits
