Q

The three economic questions & how to explain

A

What & how much to produce? How to produce? Who to produce for?

How to answer
What & how much to produce?
- The market indicates through relative prices the needs and wants of society which ultimately signals to producers where resources should be allocated

How to produce?
- Producers are profit-motivated thus they will choose the lowest-cost method of producing

Who to produce for?
Wages determine who gets what in a market economy
e.g. surgeons make more bc there’s less supply of surgeons and they are inelastic to society

Q

What is the difference between a shift in the demand curve and a movement along the demand curve? (DISC PP)

A

A shift is caused by changes in non-price factors: [DISC PP] = a movement along supply curve
- disposable income
- substitute & complementary product prices
- preferences & tastes
- interest rates [tax, etc]
- population demographics
- consumer confidence

Movement along the curve is caused by price factors:
- meaning a change in the price of the g+s itself

Q

Disposable income + Discretionary income

A
  • The money available for spending or saving after personal tax has been paid
    = wages - taxes + transfers
  • Disposable income available for spending and saving after an individual has paid for non-avoidable expenditures

Demand factor
- Increase $ = increase in demand of g+s as consumers have more purchasing power.
–> demand curve shifts to the right
- vice versa = Decrease mean shift to the left

Q

What is the difference between a shift in the supply curve and a movement along the supply curve?

A

Non-price factors cause the supply graph to shift [CP COST] = a movement along demand curve
- cost of production
- # of suppliers
- tech
- productivity
- climactic changes

Price of the g+s causes an expansion or contraction of the supply curve

Q

Non-material living standards

A

The aspect of a persons quality of life that cannot be measured by monetary factors

29
Q

what is the impact of a change in relative prices

A

Act as signal to producers to investigate market, leading to reallocation of resources better to adhere to society’s needs & wants if profit making opportunities exist

30
Q

elasticity

A

The responsiveness of quantity demanded or supplied to a change in price [in terms of %]

31
Q

Change in PED/PES is measured by:

A

% change in Qd/Qs [quantity demand/supply] / % change in $

32
Q

Inelastic vs elastic curves for PES & PED

A

formula: PED/PES = % Change in QTY Demanded or [supplied] / % Change in Price

Inelastic curves = steep
- Qs/Qd is unresponsive to changes in price
- PED/PES < 1

Elastic curves = flat
- Qd/Qs is responsive to changes in price
- PED/PES > 1

33
Q

High price elasticity of demand/supply means that:

A

A change in price will lead to a relatively large change in Qd/Qs

34
Q

Low price elasticity of demand/supply means that:

A

A change in price will lead to a relatively small change in Qd/Qs

35
Q

Factors that impact PED include:
TPAN

A
  • degree of necessity
  • availability of substitutes
  • Proportion of income
  • Time
36
Q

factors that impact price elasticity of supply (inelasticity) [PSST D]

A

Production Lag – If there’s a long time needed to produce more of a good (e.g., growing crops), supply tends to be inelastic.

Spare Capacity – If there is little or no spare capacity (e.g., factories running at full capacity), supply is inelastic because it’s hard to increase production quickly.

Stock Levels – Low levels of stock make supply inelastic because producers can’t quickly respond to changes in demand by selling more.

Durable goods - elastic supply
non-durable = inelastic supply

Time – In the short term, supply is generally inelastic because it takes time to increase production. Over the long term, supply can be more elastic as firms can expand capacity.

37
Q

Allocative efficiency

A

Point on PPF where the collective needs and wants of society are being maximised
- No one can be made better off without making someone else worse off

38
Q

Technical/productive efficiency

A

point on ppf where resources are allocated such that maximum output is achieved with minimal inputs
- At productive efficiency we cannot produce anymore

39
Q

Dynamic efficiency

A

Is how quickly resources can be reallocated to meet the changing wants and needs of consumers
- On PPF it determines how quickly we can move from one point of production to another point

40
Q

Inter-temporal efficiency

A

Where resources are allocated to focus on balancing out the current needs + wants of society w the future needs + wants

point on ppf with the optimal balance of resources between now and the future

41
Q

Efficient allocation of resources

A
  • Where resources are allocated such that society’s well-being is maximised, and opportunity cost is minimised.
  • No other possible combination of goods and services could provide a better standard of living
42
Q

Many buyers and sellers

A

Means that no party can influence price, everyone is a price taker; increased comp

43
Q

Products are homogenous

A

Means that suppliers must compete on price

44
Q

Ease of entry and exit to and from markets

A

Means that resources can be reallocated quickly between markets

45
Q

Public goods

A

Market failure
- Goods and services that are non-excludable (producer cannot stop the consumer from consuming product)
- non-rivalrous (one party’s consumption does not impact another)
- Market has failed to achieve efficiency as it will be underproduced by the market [not socially optimal]
- reduces allocative efficiency

46
Q

Common access resources

A

Market failure
- Goods and services that are non-excludable (producers cannot stop consumers from consuming the product)
- rivalrous (one party’s consumption does impact another)
- Overconsumed & depletable thus not available long-term; reducing _ & inter-temporal efficiency

47
Q

4 forms of market failure PEA C

A
  • Public goods
  • Common access resources
  • Externalities
  • Asymmetric information
48
Q

Externalities

A

Cost or benefit imposed on a third party not directly involved with the production or consumption of the good and service

49
Q

Negative externality

A

cost imposed on 3rd parties; this will cause an over-allocation of resources because the producer or consumer will not consider the social cost

50
Q

Positive externality

A

Will cause an under-allocation of resources because the producer or consumer will not consider the social benefit

e.g Positive externalities in consumption refer to the positive effects on a third party (not the producer or the purchaser/consumer of a product) that arises out of the consumption of a particular product. One such good is the Covid-19 vaccines, which helps to protect the promote the initial user but also promotes herd immunity when more people consume it, which protects the health of third parties or those who refuse to, or are unable to, take the vaccine (due to health reasons).

51
Q

Asymmetric information

A

Where one party to a transaction knows more about the product than the other party

  • Efficiency is not achieved as a market may over-allocate for things society does not need/want and under-allocate resources for things society wants but did not know they wanted bc they didn’t have enough information
52
Q

Direct government provision

A

Where the government provides the good or service to society

  • By providing G+S the government is effectively shifting the supply curve to the right [higher quantity and lower price at equilibrium]
53
Q

Government regulation

A

Where legislation imposes restrictions on the use of specific resources

  • Gov will make and enforce laws that intervene in the market to achieve a more efficient outcome
54
Q

Indirect taxation

A

A source of government revenue, cost is applied to the production of goods and services causing the final price of good/ service to increase

  • Indirect tax is levied on producers & passed onto consumers e.g. prods must pay an amount per unit produced & then consumers must pay extra
  • Shift the supply curve to the left [increase the cost of production thus decreasing Qs]
55
Q

Government subsidy

A

Financial assistance provided by the government to a producer - is offered to ensure the production of certain goods and services

  • Payment to suppliers to encourage production & therefore, consumption of a G+S
  • Subsidies reduce the cost of production therefore shifting the supply curve to the right
  • Decreasing prices for consumers
56
Q

market failure

A

where the forces of demand+supply and the price signal causes an allocation of resources which fails to maximise society’s utility

-> where the market does not achieve efficiency

57
Q

private goods

A

market success
- excludable
- rivalrous
-> more profit for producers

58
Q

regulatory capture

A

regulatory agency is influenced or dominated by the industries it regulates, leading to decisions that favor those industries over the public interest; a higher-up being bribed to be more flexible with the briber

59
Q

An unintended consequence of government intervention in the labour market on market failure

A

Minimum wage is intended to help ensure a fair income for workers and to reduce poverty. However, an unintended consequence that leads to market failure is that if its set too high unemployment rates will rise at it increases the labour costs for businesses and leads to an overall reduction in g+s produced; decrease productivity and efficiency

60
Q

government failure

A

When government intervention leads to an inefficient allocation of resources and a net welfare loss.

61
Q

equilibrium point

A

the point where demand equals supply, where there is no shortage, no surplus & the market clears.

62
Q

types of resources

A

Land - things that exist naturally on earth e.g. water & minerals
Labour - human effort e.g. teachers or real estate agents
Capital - anything that is human-made & used to produce goods & services e.g. machinery, equipment & tech

63
Q

what does a graph need

A
  • title
  • downward sloping demand curve
  • upward sloping supply curve
  • p$
  • Q100
  • Equilibrium point
  • label shifts/movements with numbers and arrows
64
Q

how markets clear shortages

A

consumers will bid up prices to buy scarce G + S
- contraction along demand curve

suppliers will respond to the increased prices by reallocating resources towards that market
- expansion along the supply curve

65
Q

How markets clear surpluses

A

suppliers discount prices clear excess stock [profit motive]
- Contraction along the supply curve

consumers will respond to the decreased prices by consuming more [income/substitution effect]
- Expansion along the demand curve

66
Q

How to correct under-allocation of resources [public goods & negative externalities]

A
  1. The supply curve will shift to the [left/right]
  2. The price will [increase/decrease]
  3. [More/less] resources allocated to this market
67
Q

“impact on the market for blah” means you must
- Explain shifts in equilibrium

A
  1. Determine the demand or supply factor that caused the shift
  2. Determine the impact of the shift on price, [contraction/expansion] in demand, [higher/lower] Qd on what is affecting the target market
  3. [increase/decrease] demand for _ market, the demand curve shifts [left/right], D0-D1
  4. p0 leads to [surplus/shortage] Q0-Q1, signals $ at P0 are too [high/low]
  5. [reduce/increase] $ to clear market
68
