Supply and costs


Learning Outcomes

By the end of this section students will be able to:

understand and utilize the concept of elasticity of supplyidentify the factors of productiondistinguish between fixed and variable factors of productionanalyse the relationship between costs and output in the

short run and long runestablish the relationship between costs and the supply

curveunderstand the reasons for economies of scaleidentify methods and rationale for growthdistinguish between social and private costs



Price elasticity of supply

Elasticity of supply measures the responsiveness of supply to a change in price.

This relationship may be expressed as a formula:Percentage change in quantity supplied ÷ Percentage

change in priceWhere supply is inelastic it means

that supply cannot easily be changed, whereas elastic supply is more flexible.



Factors affecting price elasticity of supply

capacity / resource mobility


Supply elasticity

How readily can a destination cope with sudden increases in demand?E.g. the Cole Classic Marathon

Swim, Bondi BeachHotels?Rubbish clearance?Cafes?Parking?Water?Snacks?Ice creams?Roads?


Supply and costs

Leisure and tourism inputsLand

This includes natural resources such as minerals, and land itself.

LabourThis includes skilled and unskilled human effort.

CapitalThis includes buildings, machines and tools.

EnterpriseThis is the factor which brings together the other

factors of production to produce goods and services.

Short and long run costs

What happens to average short run costs of a hotel as occupancy falls?

How will the hotel respond to a long run fall in occupancy?

How do hotels benefit from economies of scale?

Are there any potential dis-economies of scale?


Social and private costs

Private costs of production are those costs which an organization has to pay for its inputs. They are also known as accounting costs since they appear in an organization’s accounts.

Social costs do not appear in an organization’s accounts and do not affect its profitability, although they may well affect the well-being of society at large.


Private and social costs

What are the social costs?
