Q

Price mechanism - Rationing Device.

A
  • Resources are scarce, which means that goods and services produced from them are limited in supply
  • Price mechanism allocated these goods and services to those who are prepared to pay for them.
  • In effect, Price will rise or fall until equilibrium is reached between the quantity demanded and quantity supplied

Q

Price mechanism - Incentive Device.

A
  • Rising prices tend to act as an incentive to firms to produce more of a good or service since higher profits can be earned
  • Rising Prices also means firms are able to cover extra costs involved with increasing output

Q

What does a Specific Tax do to the supply curve?

A

Causes a parallel shift left of the supply curve.

36
Q

How does an Ad Valorem Tax Affect Supply?

A

Cause a pivotal rotation of the supply curve to the left.

37
Q

What is the Incidence tax?

A

The distribution of the tax paid between consumers and producers

38
Q

Incidence of tax falls partly on consumers and producers what causes this?

A

The elasticities of Demand and Supply for the good or service

39
Q

What Elasticities cause cause most of the incidence of a tax to be put on consumers?

A

•Combination of price inelastic demand and Price elastic supply
- Addictive Goods such as tobacco tend to make goods price inelastic in demand
• Firms Can then pass the burden on tax onto consumers via higher prices

40
Q

What causes producer get get most of the incident tax?

A
  • Combination of price elastic demand and price inelastic supply
  • Less to a significant reduction in output and employment
  • Therefore Government May be reluctant to do this.
41
Q

What is a Subsidy?

A

Is a grant, usually provided by the government, to encourage suppliers to increase production of a good or service, leading to a fall in its price.

42
Q

Who is a subsidy paid to?

A

Producers

43
Q

How do producers respond to a Subsidy? And what happens to the market price?

A
  • Firms Increase Output

- Market price falls and indirectly passes on some gain to the consumers

44
Q

When given a Subsidy what type of product causes the market price to fall by a relatively large amount?

A

If demand for the good is relatively price inelastic

45
Q

When given a Subsidy what causes the market price to fall by a relatively small amount?

A

If the demand for the good is price elastic

46
Q

What happens to the gain that consumers get from a Subsidy if the good being subsidised is Demand is price inelastic?

A

Benefits to the consumer is increased

47
Q

What happens to the gain that consumers get from a Subsidy if the good being subsidised is Demand is price elastic?

A

Less gain for consumers

48
Q

What do economists assume about the way consumers behave?

A
  • Consumers behave in a rational manner and so allocate their income to buy goods and services to maximise their utility (Note some income may be saved for the future of the utility gained is greater than current spending on extra items)
49
Q

What causes Consumers to be irrational?

A
  • Influence of other people’s behaviour
  • Importance of habitual behaviour
  • Consumers weakness at computation
50
Q

What are Economic models based on?

A

Consumers are expected to aim to maximise their utility

51
Q

Why might a consumer seem irrational?

A

Consumers may seek a satisfactory level of utility rather than maximising it.

52
Q

Why consumers are irrational - The influence of other people’s behaviour.

A
  • Consumers are influenced by the behaviour of others
  • ‘herd like’ mentality is often displayed in various markets.
  • Consumers that come late often receive little benefit
53
Q

Why consumers are irrational - The importance of habitual behaviour.

A
  • Consumers prefer what they know and have, rather than risking something new where there is more uncertainty.
  • Takes up time with paperwork, some consumers prefer doing nothing
  • Consumers are often unrealistic about their future behaviour
54
Q

Why Consumers are irrational - Consumer weakness at Computation.

A
  • Many consumers have difficulty calculating the Best Buy
  • Imperfect information is a consumer weakness, consumers do not always buy a good at the cheapest price or a good of the best quality since market do not always operate efficiently.
55

59
Q

Producer surplus is…

A

Is the extra earnings obtained by a producer above the minimum required for them to supply the good or service

60
Q

An excess demand for a good will price to […….] until equilibrium is reached.

Rise

61
Q

An excess supply of a good will cause price to […..] until equilibrium is reached.

A

Fall

62
Q

A

1- Inward
2- Fall
3- Rise

63
Q

A unit subsidy on a good will cause an 1-[…….] shift in the supply curve, leading to a 2-[……….] in output and a 3-[………] in price.

A

1- Outward
2- Rise
3- Fall

64
Q

Alternative views of consumer behaviour are based on […………………..] of how consumers actually behave.

A

Real-World investigations

65
Q

What can Private Benefits also be referred to as?

A

The revenue that a firm obtains from selling a good or service

66
Q

What are Social Benefits?

A

The sum of external benefits and private benefits from a market transaction.

67
Q

By adding [……..] to [………] we get Social Benefits.

A

By adding private benefits to external benefits we get social benefits

68
Q

External benefits are the difference between what?

A

Private benefits and social benefits

69
Q

The marginal private benefit and the marginal social benefit curves often…

A

Diverge

70
Q

Because marginal private benefit and marginal social benefit curves diverge what does this mean?

A

That external benefits increasing disproportionately with output consumed.

71
Q

In what instance will the marginal private benefit and the marginal social benefit be drawn parallel to each other??

A

In the case that external benefit per unit consumed will remain constant

72
Q

When looking at Market Failure, What is the Supply Curve also equal to?

A

The marginal private cost curve (MPC)

73
Q

What does the addition of the Marginal Private Cost (MPC) Curve do?

A

Forms the market supply curve

74
Q

When looking at Market Failure, the Demand curve for consumers is?

A

The marginal private benefit curve (MPB)

75
Q

When looking at the Marginal Private Benefit, what do economists assume?

A

That it is possible to measure the benefit obtained from consuming a good by the price people pay for it.

76
Q

As an individual consumes more of a good, the marginal utility (marginal benefit) [………..]

A

Falls

77
Q

Why does the Demand curve slope down?

A

Because of diminishing marginal utility

78
Q

What is Market Equilibrium?

A

Where Marginal Private Benefit equals Marginal Private Cost

79
Q

What is the Social Optimum?

A

Where marginal social benefit equal marginal social cost

80
Q

What is achieved when social optimum equilibrium is reached?

A

Welfare maximisation

81
Q

What does the free market ignore?

A

Negative and Positive externalities

82
Q

In Market Failure, when adding the external costs on the production of a good or service, what happens to the supply curve?

A

Supply curve PIVOTS left and becomes the marginal social cost curve

83
Q

In Market Failure, what happens to the demand curve when external benefits are added on to the consumption of the good?

A

Demand curve PIVOTS to the right, making the marginal social benefit curve.

84
Q

How do External Costs cause Market Failure?

A

External costs are ignored by consumers and and producers when they make their economic decisions

85
Q

What are some of the impacts of external costs on consumers and producers?

A
  • Overproduction (deee Market Level of output exceeds the social optimum level of output)
  • Underpricing (since the free market price is below the social optimum price)
  • Welfare Loss (since marginal social costs exceed marginal social benefits)
86
Q

What are some of the impacts of external benefits of consumer and producers?

A
  • Underproduction ( Free Market Level of output is less than the social optimum level)
  • Underpricing ( Free Market Price is below the social optimum price)
  • Potential Welfare vain (since marginal social benefits exceed marginal social costs)
87
Q

What are Public goods?

A

Those goods that have non-rivalry and non-excludability in their consumption.
