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
Internal: Technical
Specialisation large organisations can
employ specialised labour Indivisibility of plantmachines cant be
broken down to do smaller jobs!
Principle of multiples firms using more
than one machine of different capacitiesmore efficient
Increased dimensions bigger containerscan reduce average cost

Economies of Scale
Indivisibility of Plant:
Not viable to produce products like
oil, chemicals on small scale need large amounts of capital
Agriculture machinery
appropriate for large scale work combines, etc.

Economies of Scale
Principle of Multiples:
Some production processes need
more than one machine
Different capacities
May need more than one machineto be fully efficient

Economies of Scale Principle of Multiples: e.g.
Machine A Machine B Machine C Machine D
Capacity =
10 per hour
Capacity =
20 per hour
Capacity =
15 per hour
Capacity =
30 per hourCost = 100per machine
Cost = 50per machine
Cost = 150per machine
Cost = 200
per machine
Company A = 1 of each machine, output per hour = 10
Total Cost = 500AC = 50 per unitCompany B = 6 x A, 3 x B, 4 x C, 2 x D output per hour = 60Total Cost = 1750AC = 29.16 per unit
