Q

Relative Prices

A
  • Price of any good or service, compared to the price of another
  • Send signals to market about what to produce
  • Increase in relative prices due to increase in demand tells supplier to use the resources to provide for this good

Q

Price of Substitutes - Demand (Movement)

A

Price of one item in a market falls relative to another that it can be easily substituted for.

Lower priced items demand will increase relative to the higher priced item

17
Q

Interest rates - Demand (Shift)

A

the additional costs associated with repaying a loan
interest rates low - increase in demand
interest rates high - decrease in demand

18
Q

Consumer Confidence - Demand (Shift)

A

degree of optimism consumers have regarding their future income, employment and overall economic situation

Increase consumer confidence - increase in demand
Decrease consumer confidence - decrease in demand

19
Q

Cost of Production - Supply

A

Costs associated with accessing the goods required to produce goods

Increase in cost - Decrease in Supply
Decrease in cost - Increase in Supply

20
Q

Climatic Conditions - Supply

A

way in which incidences such as floods and fires may create a more or less favourable condition to produce

21
Q

Types of efficiency

A

Allocative
Productive
Dynamic
Inter-temporal

22
Q

Allocative Efficiency

A

resources are allocated that the goods and services produced achieve maximum satisfaction

23
Q

Productive Efficiency

A

producing maximum amount of goods and services from the minimum amount of resources

24
Q

Dynamic Efficiency

A

move to a allocatively efficient point following changes to supply and/or demand

25
Q

Intertemporal Efficiency

A

balance between resources used for current and future needs

26
Q

Market Failure

A

Market hasn’t achieved allocative efficiency as their has been an under allocation or over allocation of resources

27
Q

Reasons for Market Failure

A

Public Goods
Asymmetric Information
Externalities
Common access goods

28
Q

Public Goods

A

Public goods are provided by the government for the benefit of everyone

It creates the free rider problem – payment is difficult to extract from those who benefit from it.

If operating in a free market – an under allocation of resources

The government typically intervenes in these markets to ensure that adequate resources are allocated

The government will pay for these public goods using revenue raised from a range of sources including taxes.

29
Q

Externalities

A

the costs or benefits for third parties that arise when goods and services are produced or consumed.

Can be positive externalities or negative externalities.

Buyers and sellers ignore impact of externalities when making decisions - resource allocation becomes inefficient.

30
Q

How can government intervene in Externalities

A

regulations and laws (CleanEnergyAct)
•Indirect taxes (excise tax on tobacco, CarbonTax)
• Providing subsidies (incentives for solar panels)
• Education and advertising to inform the public (anti-smoking ads)

31
Q

Asymmetric Information

A

where buyers or sellers lack the information required to make decisions about how to use their resources.

one party knows more than the other about the product and this can lead to inefficient outcomes.

The Government can again use legislation such as labeling of ingredients on foods.

32
Q

Common Access Resources

A

Natural resources that are usually not owned by anyone.

Generally can be accessed by all members of the community and used without payment.

Non-excludability - means that it is difficult or impossible to exclude individuals from using the resource.
Rivalrous - means that one person’s use of a resource reduces or prevents another person’s use of it.

33
Q

Government Failure

A

government intervened in a market resulting in a more inefficient allocation of resources (market failure) and worse living standards.

34
Q

Price Ceilings

A
  • Goods/services can’t be sold above a certain prices.
  • The intention may be to make items affordable for low income earners (perhaps affordable rent for example)
  • However, they often create a shortage and black markets operate.
35
Q

Price Floors

A
  • are prices cannot go below a certain level
  • The intention would be to protect the income of those selling the products (for example, minimum wages in the labour market)
  • However, they often result in ongoing surpluses
36
Q

Price Elasticity of Demand

A

change in demand relative to the change in price.

  • High PED (elastic) – demand greater than change in price
  • Low PED (inelastic) – demand will be lower than the change in price
  • Medium PED (unit-elasticity) – demand is equal to the change in price
37
Q

Factors Affecting PED

A

Degree of necessity
Availability of substitutes
Proportion of income
Time

38
Q

Price Elasticity of Supply

A

change in supply relative to the change in price.

  • High PES (elastic) – Percentage change in qty will be greater than the percentage change in price
  • Low PES (inelastic) – Percentage change in qty will be lower than the percentage change in price

•- Medium PES (unit elasticity) – Percentage change in qty will be equal to the percentage change in price

39
Q

Factors affecting PES

A

Production period
Spare capacity
Durability of goods

40
Q

Effects of changes in supply and demand on equilibrium prices and quantity traded

A

Increase demand

  • shift demand curve right
  • expansion along the supply curve
  • new equilibrium at higher prices and quantity

Decrease demand

  • shift demand curve left
  • contraction along the supply curve
  • equilibrium at lower prices and quantity

Increased supply

  • shift supply curve right
  • expansion along demand curve
  • equilibrium at lower prices and higher quantity

Decrease supply

  • shift supply curve left
  • contraction along the demand curve
  • equilibrium at higher prices and lower quantity
