Consumer sovereignty exists- consumers direct/allocate resources
large number of buyers and sellers, of which, none have market power (price takers)
homogenous products (identical+ easily substitutable)
ease of exit and entry (low startup costs, regulations etc)

Q

supply

A

Willingness and ability of suppliers/ producers to supply/produce

22
Q

law of supply

A

as price increases so to do supply, as it decreases so to does supply

23
Q

microeconomic supply non-price factors

A

change in cost of production
number of suppliers
technological changes
productivity
climatic conditions

24
Q

market equilibrium

A

buyers and sellers interact in the market to determine selling price and quantity
equilibrium–> where qty demanded for g/s= quantity supplied of that g/s

25
Q

7 steps for shift in demand/supply

A
  1. explain situation in own words-> NP factor
  2. supply or demand
  3. increase/decrease
  4. shift curve right or left
    5.if at constant P1, temporary shortage/ surplus
  5. market forces put upward/downward pressure on price to adjust to a new equilibrium, E2, with a cont/exp in curve, and a cont/exp in other curve
  6. Overall impact on P+Q
26
Q

Price Elasticity of demand formula

A

%quantity demand/%Δprice

27
Q

Price elasticity of demand definition

A

the responsiveness of total quantity demanded of a product to changes in the price of that product

28
Q

factors effecting price elasticity

A

The degree of necessity- more needed-> purchase at any price

Availability of substitutes- more substitutes means can swap if prices go up

Portion of income, greater % of income-> up effect of % price change

time, short term-> cons= habitually consume, long term-> start to realise price changes-> price shock -> change consumption

29
Q

significance of price elasticity of demand

A

Bus- pref low PED-> low effect of Δprice

bus take PED into account when Δprice, ie if high elasticity, sales= profit

govt consider PED when Δindirect tax

30
Q

Price Elasticity of Supply

A

the resposiveness of quantity supply to changes in price

31
Q

price elasticity of supply formula

A

PES=Δ%Supply/Δ%price

32
Q

factors effecting Price Elasticity of Supply

A

Spare capacity- resources
production period
durability of goods

33
Q

Significance of PES

A

The PES can affect the economic viability of a business sell as they’re ability to respond to changing price signals.

34
Q

market/price mechanism

A

describes how the forces of supply and demand inlfluence (relative) prices of goods and services, which then coordinates the way productive resources are allocated in the economy

35
Q

relative prices

A

the price of a good or service relative, or compared with another

36
Q

key points for relative prices and reallocation of resources

A

Price Mechanism describes how the forces of demand and supply influence prices of goods and services and in turn relative prices of goods and services which then coordinates the way productive resources (such as labour and capital) are allocated in the economy.
Changes in relative prices send clear price signals to producers and consumers who investigate the reasons for the changes and hence determine whether to reallocate resources (if demand driven)

37
Q

how does market system/ resource reallocation–> living standards

A

materially-> uphold consumer demand by produing what is demanded by producers, hence decreasing price of g/s–> increase Mat LS
non materially-> increased production to meet consumer demand may –> more pollution in order to rappidly meet consumer demand.

38
Q

effect of pure competition on allocative efficiency.

A

No barriers to entry and exit means that producers can quickly move they’re resources in order to fulfil an emerging social need for a particular good or service–> allocative efficiency

39
Q

effect of pure competition on productive efficiency

A

Low barriers to entry and exit combined with mobility of resources +Many sellers = high levels of competition. to be competitive, producers mustminimise costs and maximise output to be able to compete and winmarket share through low possible selling prices.

40
Q

effect of pure competition on dynamic efficiency

A

low barriers to entry and exit means businesses can rapidly shift between markets or products in order to adapt to emerging economic condition.

41
Q

effect of pure competition on inter temporal efficiency

A

due to immense need for productive efficiency to be competitive, businesses may not consider inter temporal efficiency in decision making, prioritising short term gain without considering the long term negative externalities for future generations ( such as pollution and degradation of resource pool). Hence limiting inter temporal efficiency

42
Q

market failure

A

What an unregulated market is unable to allocate resources efficiently or where resources are allocated in such a way that national living standards or welfare is not maximised. It will result in an over allocation of resources to the production or consumption of some goods or services and an under allocation to others

43
Q

public goods

A

Goods/services available for all people to use, gain benefit from all enjoy socially desirable and important to all even if poor.

Nonexcludable – you cannot exclude nonpayers from enjoying the benefits that they good or service is provided which gives rise to the free ride a problem.

Non-depletable/non-rivalrous in consumption – one persons consumption does not diminish the ability of another person to enjoy the same consumption so all benefit equally

44
Q

forms of govt intervention for public goods

A

Government subsidies – a payment or concession of a producer or consumer that is designed to increase consumption/production of a good or service by covering some of the costs involved. = cash payment, low or no interest loan, subsidised costs.

Direct government provisions – governments directly produced the good or service such as Lighthouse, public lighting, defence, education.

45
Q

Common access resources

A

resources which are benificial to society, and are depletable ( consumption prevents further consumption ), but is non excludable (cannot restrict individuals from accessing them in a free market), hence, have no market price.

46
Q

CAR Market failure

A

in an unregulated market, given businesses are profit driven, they will over consume the common access resources–> depletion of common access resources which limits inter temporal efficiency

46
Q

CAR govt intervention

A

Legislation used to reduce consumption of common access resources through permits, quotas or setting and monitoring areas.

Indirect taxes–> carbon tax/ ETS
–> places a price on they’re consumption

subsidies–> used to encourage clean technologies
under Renewable energy target scheme, Govt subsidies+ dev–> implementation of techs

47
Q

externalities+ why market failure

A

externalities refer to the effect of production or consumption on an uninvolved third party.

Market failure because businesses in an unregulated market seek only profit, overlooking the effect that they’re production has on an independent third party. Hence not maximising the living standards of the nation as production/consumption with negative externlities (such as cigarettes or alcohol) is overproduced, while prod/cons with positive externalities( such as healthy foods or vaccinations) = underproduced

48
Q

how does govt correct market failure of externalities

A

subsidies
direct govt provision–>. health+edu+ research+dev= csiro

govt regulations, –> legislation to inhibit or limit production/ consumption
indirect taxes

49
Q

asymmetric information

A

a type of market failure whereby one economic agent has less than the other, hence perfect information about the value of the good or service is unknown, hence causing inefficient allocation of resources.

50
Q

govt intervention for asymetric information.

A

govt regulation–> x allow any misleading info. ACCC-> Competion and consumer act 2010

govt awareness advertising–> benefits of eating fresh veg+ smoking drinking gambling

subsidies–> provide subsidies to firms who provide meaningful info to cons.

51
Q

government failure+ example

A

whereby the government aims to address one economic problem but in doing so minimises the living standards of the nation. For example, the introduction of minimum wage–> inefficient market system
