Q

How can undercut taxes be used to alter the level of demand

A

Indirect taxes can be used to raise the price of de-merit goods and products with negative externalities designed
to increase the opportunity cost of consumption and thereby reduce demand towards a socially optimal level.

Q

How can subsidies be used to alter the level of demand

A

Subsidies to consumers will lower price of merit goods. They are designed to boost consumption and output
of products with positive externalities
– remember that a subsidy causes an increase in market supply and leads
to a lower equilibrium price.

Q

Arguments in favour of a sugar tax

A
  1. External costs of consuming sugary drinks – are a cause of market failure
  2. Information failures – people under-estimate the long-term costs of their consumption
  3. Sugar tax raises revenue – ring-fenced for other projects e.g. to help fund school sports / breakfast clubs
  4. Tax encourages manufacturers to re-formulate and offer healthier
    alternatives e.g. in vending machines

Q

Arguments against a sugar tax

A
  1. Might be regressive on lower income families – i.e. the tax might be inequitable
  2. Other policies might be more effective in cutting consumption in the long-term (e.g. better information)
  3. People might simply switch to other sugary products = ineffective
  4. Risk of lost jobs in pubs and shops that rely heavily on drink sales

Q

How much does a subsidy cost and who benefits?

A

o Is a subsidy part self-financing? Will it create more tax revenue?

Q

What is a maximum price?

Main aim, how to set price effectively

A

• legally imposed maximum price in a market that suppliers cannot exceed.
- A maximum price is introduced in an attempt to prevent price from rising above a certain level.
• aim of max is equity so that goods are more widely available to the general population.
• To be effective as a form of intervention, a maximum price has to be set below the existing free market equilibrium price

Q

Question: Assess the case for introducing rent controls in the UK

A
  • rent controls are form of max price
  • to be effective in changing resource allocation, needs to be set below normal equilibrium price
  • effects of rent control shown in diagram
  • as a result of capped R2, demand expands, so is more affordable
  • see from diagram that supply decreases
  • = disequilibrium as shortage due to excess demand

Q

What is carbon emissions trading?

A
  • uses the market mechanism to change relative prices and the incentives
  • Businesses need to buy enough emissions allowances – the higher the price, the greater the incentive to cut pollution
  • Carbon trading provides a quantity adjustment to CO2 emissions

26
Q

Pure public goods are usually provided – perhaps to a basic standard – by the state on the grounds of:

A

Fairness
Efficiency
Social welfare

27
Q

Provision of Information

A
  • health warnings
  • nutritional labelling
  • gamble aware
  • industry standards
28
Q

Regulation to correct externalities

A
  • smoking bans
  • minimum age
  • max co2 emissions
  • speed limits
29
Q

What is Government Failure?

A

• When government intervention in market leads to less efficient allocation of resources and makes situation worse
• government intervention to correct market failure leads to a net social welfare loss.
costs> benefits

30
Q

3 words that government intervention can be

A
  • ineffective
  • inequitable
  • misplaced
31
Q

Examples of unintended consequences:

A
  • Bank bail-outs – raises the problem of moral hazard

- Import tariffs on steel – hits domestic car and construction firms

32
Q

What is regulatory capture?

A
  • Regulatory capture is a form of government failure
  • It happens when a government agency operates in favour of producers rather than consumers
  • This often happens when suppliers have significant lobbying power e.g. with government agencies
33
Q

main causes of regulatory capture?

A

• Asymmetric information – regulators may rely on critical information supplied by regulated firms themselves
about costs, investment requirements
• Under-resourced – regulatory agencies may not have enough funding to scrutinize an industry properly
• Information gaps – people working for a regulator may not understand the complexities of an industry e.g.
financial services – they may not understand risk

34
Q

Why does regulatory capture matter?

A
  1. Consumers interests may be harmed if regulators fail to hold suppliers to account and enforce minimum standards of service
  2. Prices will be higher leading to lower real incomes and regressive effects on lower income households
  3. There can be damaging externalities if the regulator fails to act leading to a social welfare loss
35
Q

Key revision points about government failure:

A
  1. Free market economists are distrustful of intervention. They believe price mechanism should operate.
  2. Often, we accuse the government of policy failure only with hindsight.
  3. Limited information - no government has the resources and information available to it to make fully informed, objective judgements.
  4. Government failure is most likely to occur when decisions are made in the vested interest of special interest groups, at the expense of other groups.
36
Q

How could taxes affect consumption of goods with negative externalities

A

Indirect taxes could reduce the quantity of demerit goods consumers, by increasing the price of the good.
If the tax is equal to the external cost of each unit, then the supply curve becomes MSC rather than MPC, so free market equilibrium becomes the socially optimum equilibrium
This internalises the externality, so the polluter pays for the damage

37
Q

In theory how could could taxation affect consumption of demerit goods

A

Discourage consumption and reduce negative externalities as it is more expensive

38
Q

How do subsidies affect consumption of merit goods

A

Encourage consumption of merit goods, includes full social benefit in the market price of the good, so external benefit is internalised

39
Q

Disadvantage of subsidies

A

Opportunity cost to the government + risk of firms becoming inefficient if they rely on the subsidy + government failure if they subsidies less efficient industries

40
Q

Maximum price

A

Government might set a maximum price where the consumption or production of a good is to be encouraged. This is so good doesn’t become too expensive to produce or consume

  • max prices have to be below free market price
  • prevent monopolies exploiting consumers
41
Q

Benefits of maximum price

A

could lead to welfare gain for consumer by keeping prices low
could increase efficiency in firms as they have incentive to keep their costs low to maintain profit level

42
Q

Cons of maximum proce

A

Could reduce firms profits, could lead to less investment in long run
Firms could raise prices of other goods, so consumers have no net gain

43
Q

Minimum price

A

Minimum price when consumption or production of a good is to be discouraged
Reduced negative externalities from consuming a demerit food
Above free market price

44
Q

Advantages of tradeable pollution permits

A
  • should benefit environment in the long run, by encouraging firms to use green production methods
  • the government could raise revenue from the permits, because they can sell them to firms, this revenu could then be reinvested in green technology
  • if firms exceed permit, they will have to buy permit from firms that did not use whole permit, this raises revenue for greener firms
45
Q

Disadvantages of tradeable pollution permits

A
  • but it could lead to firms relocating to where they can pollute without limits to reduce production costs
  • firms might pass higher costs of production onto consumer
  • competition could be restricted in the market if permits create a barrier to entry for potential firms
  • it could be expensive for governments to monitor emissions
46
Q

State provision of public goods

A
  • government could provide public goods which are under provided in the free market, such as education and healthcare
  • this makes merit goods more accessible, which might increase their consumption and yield positive externalities
  • it could be expensive for governments to provide education, and government will incur an opportunity costs of spending revenue
47
Q

Provision of information

A
  • by providing info, government can ensure there is no info failure, so informed economic decisions can be made
  • eg, governments might make it illegal for second hand car dealers not to reveal entire history of a car, so consumers know what they are buying
  • can be expensive to police
48
Q

Regulation

A
  • government could use laws to ban consumers from consuming a good
  • eg, minimum school leaving age is 26
  • positive externalities from laws (eg skilled workforce)
  • firms which fail to follow are fined, which disincentives them
  • potentially raises costs of firms, who might pass higher costs to consumers
49
Q

Causes of government failure

A
  • distortion of price signals
  • unintended consequences
  • excessive administrative costs
  • information gaps
50
Q

Distortion of price signals

A
  • government subsidies could distort price signals by distorting free market mechanism, could be inefficient allocation of resources because market mechanism not able to act free;t
51
Q

Unintended consequences

A
  • this is when actions of producers and consumers have unexpected, or unintended consequences
52
Q

Excessive administrative costs

A

Social benefits of a policy might not be worth the financial cost of administering the policy. It might cost more than the government anticipated, the government has to consider whether the policy is a good value for money

53
Q

Information gaps

A
  • some policies might be decided without perfect info, might require a full cost-benefit analysis, which is time consuming and expensive
  • eg, government policies are long term and have failed several times in the past
  • however it is impractical for government to gain every bit of info they need, so assumptions are made
54
Q

Example of emissions trading system

A

EU ETS 05, led to 21% reduction in GhG emissions

55
Q

Advantages of state provided public goods

A

● This ​corrects market failure by providing important goods which would otherwise not be provided. It will lead to improved social welfare.
● It can help to bring about ​equality,​ by ensuring everyone has access to basic goods.
● There will be ​benefits of the goods themselves​, for example by providing healthcare, the government ensures that the workforce is healthy and so this canimprove economic growth.
● By using competitive tenders (looked at in Theme 3), the government can ensure efficiency

56
Q

Disadvantages of state provided public goods

A

● This is ​expensive and represents a ​high opportunity cost ​for the government. Administration costs are a problem
● Since the market is not involved, the government may produce the ​wrong combination of goods as consumers can not indicate their preferences.
● The government may be ​inefficient at production since they have no incentive to cut costs.
● Government officials may suffer from ​corruption and conflicting objectives

57
Q

Advantages of provision of information

A

● This helps consumers to act​ rationally,​ which allows the market to work properly.
● It is best if the government uses this ​alongside other policies​. For example, it can make demand more elastic in the long run and so help indirect taxes to become more effective at reducing output

58
Q

Disadvantages of provision of information

A

● This can be ​expensive​ for the government to do, incurring an opportunity cost.
● The government themselves may not always have all the information, so it may bedifficult to inform consumers.
● Consumers may ​not listen ​to the information provided due to irrational behaviour

59
Q

Advantages to regulation

A

● This can ensure consideration of externalities, prevent exploitation of consumers and keep consumers fully informed. This will help to overcome market failure and maximise social welfare

60
Q

Disadvantages to regulation

A

● Laws may be ​expensive​ for the government to monitor, incurring an opportunity cost.
● Compared with tradable pollution permits, regulation is a ​less efficient method of reducing pollution.
● The government can suffer from ​regulatory capture​ (looked at in Theme 3).
● Firms may ​pass on costs​ to the consumer in the form of higher prices.
● Excessive regulation may reduce competition in a market and efficiency, byincreasing bureaucracy and reducing innovation
