Merit goods

A

Goods and services that if left to the free market would be underconsumed
Have positive externalities in consumption
May be information failure as people may not fullly appreciate looong term benefit of conusmption
Social ooptimum is still msb=msc

Increase chance better hjobs
More productive firms increase profits
Decrease ifnormation fialure

44
Q

More flexible labour markets
Invcrease productivity of workforce
Competitive advantage

45
Q

Direct provusuin

A

Gov by-pass market
Take over responsibility of fair supply of socially efficient quantity of merit goods
Eg. Nhss
Gov could also cover some cost of private sector provision- eg. Free training healthcare- may work in provate hosputal and schools

46
Q

What can be done to increase consumption of merit goods

A

Direct provision
Subsidy
Regulation

47
Q

Direct provision- pros

A

Ensures fair provision for all free at point of consumption
Gov supplies socially efficient q of merit goods
More equitable

48
Q

Direct provision- cons

A

V expensive for gov so gov increase tax
Disrupt free market
Deincentiveise firms- lack profit incentive
Overconsumption- nhs- if free may lead to moral hazard- more risks as not paying eg. Skiing

49
Q

Subsidy- merit goods- pros

A

Decrease price so more affordable
May lead to further ‘dynamic efficiency’
Improvements of production process over time

50
Q

Subsidy- cons- merit gooda

A

Expensive to cgv
May lead to subsidy capture- firms exploit gov due to informstion failure due to asymetiric info
Gov dont know exact costs

51
Q

Regulation- pros- merit good-

A

May force people to consume merit goods
Eg. Car insurance legal requirement
Can police

52
Q

Regulation- cons- merit goods

A

May have regressive effect- car insurance
Increase cost policing- opp cost-0 cost of admin
Diff to regulate
May lead to illegal activity
Freedom of choice

53
Q

What are the characteristics of a pure public good

A

Non excludable
Non deminishable in consumption
Non rejectable

54
Q

Non excludabel

A

Benefits of public goods cannot be confined to those who have paid for it
Non-payers can enjoy the benefits of consumption at no financial cost to them- free rider problem

55
Q

Non-diminishable in consumption

A

Consumption of a public good by one person does not reduce the availiability of the good to others
If good is provided for one person, it must be provided for others

56
Q

Non rejectable

A

If a public good is provided we cannot avoid it

57
Q

Example of a pur public good

A

National defence systems
Sewage and waste disposal systems
Lighthouse
National rail safety systems

58
Q

Moral hazard

A

Occurs when individuals alter behavoir because of certain gaurentees
Insure a bike- may act reclessly, not lock up, insurance company loses out as pay out more than expected
Gov may offer a gaurentee of bank deposits- could cause baank to take more risks- bail out banks

59
Q

Refulators

A

Gov set up regulators to deal with natural monopolies eg. Gas and electricity
Regulator aims to get fair prices for industry and consumers
But rly on info from firm, because sympathetic to the firm and allow. Price rises
Regulatory capture- regulators act in a favourable wway to firms they are regulating

60
Q

Free rider problem

A

Consumers that are unwilling to pay for pubic goods as they know they cannot be excluded from the benefits of their provision
Consumers have incentive to question ral willingness and ability to pay for public goods
They believe that they will be required/expected to contribute to financing th public good
Eg. Tv licence doges
Markets work best when g&s are private- rival and excludable
Og often financed through some form of enforcement- compulsory nature of tv licence

61
Q

Why does the state provide public goods

A

Equity- all levels of incomee can access- provision on grounds of need rather than ability to pay
Efficiency- easuier to provide collectively, economies of scale from providing to all- large quantities are cheaper
Overcome free rider problem- correct for market failure- failure of markets to provide sufficient pg

62
Q

Semi public (quasi) public goods

A

Public in nature but dont exhibit fully the features of non-excludability and non-rivalry
May become non-rival- eg. Peak time- congestion
Equity- gov may provide these goods directly and finance with general taxation
Element of excludability/rivals in consumption
Motorrways and major roads- congestion
Police force protection- if called to another case

63
Q

Changing nature of public goods

A

Advaneces in technologyy mean the blurring of the distinction between public and private goods
Eg. Open source movement- information is a public good online
Smart electrionic toll roads- more excludable, have to pay if travel over, may be variabel prces depends on congestion- avoids free rider problem- but cause more congestion on minor roads

64
Q

Public goods/market failure and free riders

A

With public goods private sector markets may fail to supply in part of in whole with optimim q of pg
Not norms providing by private sector- no profit- free rider
So not provided at all in free market- missing market
Up to gov to decide what level pg appropriate- not social benefits for making accessible
Public body- incients where no one is excluded from damage- global warming- worldwide damage

65
Q

Information failure

A

Type of market failure where individuals/firms may lack info about econ decisions

66
Q

Types of information failure

A

Information assymetries
Failure to disclose info
Difficulty in estimating costs and benefits
Lack of education.awareness
Framing issues

67
Q

Information asymmatries

A

One party has access to info that another party doesnt
Eg. Selller of a car may knwo that it has some problem but buyer not aware

68
Q

Failure to disclose info

A

Ageents may not make full fisclosure
Eg when apply for ehalth insurance fail to inform about genetic traits/current ill health
Leads to asymmetric infor

69
Q

Difficulty in estimating costs and benefits

A

Often diff to be aware of social costs of goods
Accounting costs easy to know
More intangble external cost- eg. Producing energy from coal powerest station- mpc to firm- labour cost and cost of coal
But external cost- releasing co2 v diff, estimate monetary cost of pollution in both now and in the future

70
Q

Lack of education/awareness

A

Merit and demerit goods decrees info failure
Consumerrs unaware true personal cost/benefit
Eg tobacco dont knwo ifll effects on health
Sugar0- unaware amount sugar in processed food, harmful effect of sugar on health

71
Q

Framing issues

A

Consumers inffluenced how good is portrayed
Eg. Orange juice- healthy as vit c, but high level sugar, may hide sugar as ‘dextrose, glucose’

72
Q

Price cieling

A

A price above which it is illegal to trade
Max legal prices- distort markets by creating excess demand
Households rationed by quantuty

73
Q

Impact of price cielings

A

Queues and waiting lists occur
Interfere with incentive function- prevents attractiveness of new firms to market
Emergence of informal/shadow/black market
Emerge when primary//free market prevents from working properly

74
Q

Price floors

A

A price below which it is illegal to trade
Creates excessive supply
Eg min wage- assume set close to ffree market level- otherwise significant increase in unemployment

75
Q

Impact of price floors

A

Interfere with incentive function of prices- falling prices cause inefficient or high cost firms to leave market- prevent
May lead to increase unemployment
Cause rogue employer to break th law- paying ‘poverty wages’ to vulnerable workers such as illegal immigrants

76
Q

Private gods

A

Most goods are
Excludable- private property rights prevent other people from using the good or consumers from benefitting
Rivalry/diminishability- if consumed by one, cannot be consumed by another

77
Q

Govern,ent failure

A

When gov intervention in market leads to a net welfare loss and a misallocation of resources
Total social cost arises from intervention are greater than the social benefi

78
Q

Causes of gov failure

A

Inadequate info
Conflicting objectives
Administration cost
Unintended consequencees
Self interest
Expertise- lack of

79
Q

Inadequate infor

A

Not sufficient for politicians to make decision

80
Q

conflicting objectives

A

Value judgement
Which to speend more on
Any deciison holds opportunity cost, the gov may choose which option

81
Q

Administration ocst

A

Cost of gov intervention outweights the benefits
Eg gov spent 17.3bn to private sector for ppe and track and trace services which faileed to deliver

82
Q

Unintended consequences

A

Law of unintended consequences- ations of consumers , producers and gov always have effects that are unanticipated or unintended

83
Q

Self interest

A

Election may increase nhs spending so more popular

84
Q

Expertise (lack of)

A

Subsidie capture/regulatory capture
Diff for gov to know fair prices in services where little experience
Eg. Dentistryy- patients pay too much, insufficient prices may force dentists to switch to private practise only

85
Q

Regulatory failures

A

Regulators may limit innovation in fast growth markets
Change and expand, lack of competituve advantage
Capping prices may prevent new firms entering a market
Lack iincentive
Eg. From rent controls, energy price caps
Regulation becomes bureucratic and costly- menu costs
Regulator may be ‘behind the curve’ with new tecnology
May lack powers to be turley efective in protecting consumers
Frequent rule changes can shift business investment- eu laws

86
Q

Law of unintended consequences

A

Well intentioned legislation often acts against intentions of those its intended to serve
People and businesses find new ways to circumvent new laws
Hidden markets may develop to undermine an official policy0- black market- drugs

87
Q

Examples of law of uninetended consequences

A

Bio-fuel subsidy- may divert production awway from poorest in society-regressive effect
Import tarrifs on steel- hits domestic car and construction firms
Demerit goods- high taxes on goods such as alchol may increase demand for booze cruises abroad in france where alcohol cheaper- reduces uk tax revenue, transport increases carbon pollution, waste of resources
Landfill tax causes increase fly topping- cost to clean up and diff to prosecute

88
Q

Negative externalities of pollution

A

Poor air quality
Who air pollution global public health emergency
7 million premature deaths related to bad air quality exposure occur every year

89
Q

Costs of air pollution

A

Direct- healthcare costs resulting form respiratory diseases
Indirect- lost productivity from absenteeism or lower performance at work

90
Q

Cap and trade system success

A

Acid rain program usa 19990s
By 2015 managed to reduce sulfur dioxide emissons by 81%

91
Q

Other measures to reduce air pollution

A

London low emission zone- restrict most polluting vehicles from enternig the city centre

92
Q

Positive economic benefits of clean air zons

A

Increased compettiveness, since reducing air pollutoin can make affected areas more attractive to investors
Imporeved public health and reduction in healthcare costs leading to increased econ prdoctivity and healthier workforce
Efforst to reduce air pollution can drive innovation in clen technoogies and energy rpodcution creating new eonc opp and markets
Promote sustainable development and reduce risk future enviorn and health crises and ensure lt econ stability

93
Q

Gov failure asscoiated with price ceilings

A

Monopolists may over report its costs in order to amke gov impose a higher price ceiling
As well as creating excess suppply if above market equilibrium, or excess demand if below

94
Q

Word for cant govern overseas

A

Territoriality of jursidiction
Esp problem climate change- uk may raise environmental taxes some of highest emitters may move to countries with laxer regulation and may even increase production,- called carbon leakage
But also if less demand fossil fuels uk due to legisltaion may result in lower cost for fossil fuels, chepaer overseas and so may icrease emissions

95
Q

Merit good examples

A

Education
Healthy foods
Car insurance

96
Q

Reasons for uderconsumption of merit godos

A

Information failure- unaware potential private benefit- healthy eating hwo certain foods can lead to better health or education diff see relevance of parts of curriculum to daily livs
Afford product in free market- lowering ncome not afford healthy food, most not private education
Wider benefits to society of their use of merit goods= greater overall standard of living for society as a result of higher output and increased innovatioin ans well as ghigher tax rev for gov

97
Q

Nationalisation- shoudl it ocur

A

Socio econ arguments
Efficiency- against
Alternative snat

Loa- no

98
Q

Nationalisation should- soio econ

A

Unemployment could increase in failing industries tata steel 2016 with 15,00 jobs risked
Lead to structural unemployment- hysterisis, higher unemployment benefits, lower tax reciepts
Thus nat could lead to inverse- positive multiplier effect- positive extenrlaities on third parties- eg multiplier ect

99
Q

Alternatives nationalisation

A

Gov subsidise to reach social optimin outcome, need to be equal in size to positive externality
Yet if externality is large, better solution nat
Externalities v diff to value
Opp cost- esp if loss making firm]]

Or enable failing markets to fail such as stell, with supply side policies to pick up oiecies- occupational mobility with transferable skills, improvements geographically mobility, reducing lt and sturctural unemp
Attract fdi and other businesses to areas
Eg levelling up and northern powerhouse-e improvements infrasturcture, better access to finance, enterpsie xzones and new research centres

100
Q

Efficinecy argument against nationalisation

A

Public sector statically and dynamicallly inefficient
Public sector firms may be more allocatively efficient- ie charge prices clooser mc
Public sector managers may not have experience nor incenives, lead to x inefficinecies and overstafing
No profitg motive to be dunamically efficientless comp between firms
Environmental concerns ans safety prioritise dover prodit- conflicting objectives

101
Q

Nationalise trains essay

A

Probs not

Benefits consumer
-services reliable, prices, efficiency, safety prioritised as not trying to cut costs, accountable gov

Macro econ
-mobility of labour, cost of living - merited good want to increase provision better envrionmemt

Cost operations and efficiency
-privatisation would mean comp with each other- monopolyu price comp diagram comp comp price
Choice
-econ of scale less likely to be obtained- mes- as may prioirtise other things such as safety rather than cost
-may be ostly for gov too if lossmaking- coal 1946-1994
