Q

Advantages of indirect taxes to correct market failure
(LIE WIT)
Level of pollution

A
  • Level of pollution should fall as output of the good or service is reduced and price is increased
  • Therefore social optimum position of MSB=MSC can be achieved

Q

Define maximum price

A
  • A ceiling price set by the government on a good or service above which it cannot rise
  • It may be enforced through government legislation
54
Q

Examples of maximum price schemes

A
  • These schemes have been used in house rental markets
  • This was to protect residents fro being exploited by landlords
  • In WW2 the government imposed maximum prices on basic food items
  • E.g milk eggs and meat
  • This ensured a fairer distribution
55
Q

Examples of recent price caps

A
  • Price caps were applied on various utilities
  • E.g gas and electricity
  • Currently there are price caps on selected rail fares and postal services
  • There have been calls for the government to impose maximum wages on highly paid public sector workers
56
Q

Where is the maximum price usually set

A
  • Below the free market price

* This causes shortages or excess demand

57
Q

(real card 40)

58
Q

What does a maximum price of P1 cause

A
  • Demand extends from Qe to Q2
  • Supply contracts from Qe to Q1
  • Leads to an excess demand of Q1Q2
59
Q

What does the shortage of private rental housing lead to

A
  • Housing may be allocated on a first-come, first-served basis or by the sellers’ preference
  • Both forms of allocation have undesirable consequences
60
Q

How may the government intervene in the housing markets

A
  • The government may impose regulations on the type of consumers to who private landlords can rent
  • E.g vulnerable people or young mothers
  • However it is more likely that this type of legislation will be used for public sector housing
61
Q

Advantages of maximum prices

A
  • Reduce exploitation of consumers especially where a lack of competition exists
  • E.g the EU has capped the price of mobile phone calls across member states
  • Reduce inequality as in the case of a salary cap on highly paid public sector workers
  • Help people on low incomes to afford key products
  • E.g rental housing
62
Q

Disadvantages of maximum prices
(DURPP)
Difficult for the government to monitor and enforce maximum price controls in markets

A
  • Difficult for the government to monitor and enforce maximum price controls in markets
  • Danger of shadow markets being created
  • Some may be prepared to pay more for the good to ensure they obtain it
  • E.g tickets at popular football matches
63
Q

Disadvantages of maximum prices
(DURPP)
Unintended consequences may occur

A
  • Unintended consequences may occur
  • E.g government intervention distorts operation of price mechanism
  • This leads to an excess demand
  • This also leads to an inefficient allocation of resources
64
Q

Disadvantages of maximum prices
(DURPP)
Reduced supply of rental property in terms of the house rental market

A
  • Reduced supply of rental property in terms of the house rental market
  • This worsens the shortage in the long run
65
Q

Disadvantages of maximum prices
(DURPP)
Producer surplus falls

A
  • Producer surplus falls

* Landlords would have less income with which to invest in and maintain their property

66
Q

Disadvantages of maximum prices
(DURPP)
Problems arise over how to allocate supply

A
  • Problems arise over how to allocate supply
  • In order to meet the excess demand in the market as price cannot increase
  • This may involve a first-come, first-served basis or sellers’ preference
  • Both options are deemed to be unfair
67
Q

Evaluation of maximum prices

A
  • Depends on the difference between short-run and long-run effects of an event
  • E.g a maximum rent control may have few short term effects
  • In the long run it is likely to lead to a serious deterioration in the quality of properties
  • This is because landlords lack the funds to maintain them properly
68
Q

What is a minimum price

A
  • A floor price set by the government on a good or service below which it cannot fall
  • May be enforced through government legislation
69
Q

Where have minimum price schemes been used

A

•In commodity markets to protect incomes of farmers
•In labour markets to prevent market exploitation
(e.g national minimum wage)

70
Q

Where have there been calls for minimum prices

A
  • On goods which create high external costs

* E.g alcohol and sugar

71
Q

Minimum price effect on agriculture

A
  • EU farmers are guaranteed a minimum price for many commodities
  • E.g sugar and wheat
72
Q

Where is the minimum price usually set

A

Above the free market price, causing excess supply or surpluses

73
Q

How does a government agency respond to excess supply

A

They purchase the excess supply at the guaranteed minimum price

74
Q

What will happen if a minimum price is set below the free market equilibrium price

A

There will be no effect

75
Q

Define guaranteed minimum price

A
  • Where the surplus output created is purchased by a government agency at the minimum price
  • The main aim is to protect producer incomes
76

96
Q

What are tradable pollution permits

A
  • Pollution permits that can be bought and sold in a market

* They are an attempt to solve the problem of pollution by creating a market for it

97
Q

Why did the European Commission(EC) set up the ETS (emissions trading system)

A

To limit greenhouse gas emissions from heavy industry

98
Q

What is the ETS

A
  • A cap and trade scheme
  • An amount of carbon dioxide permits to national governments is set each year
  • Governments divide up allowances among firms covered by the scheme
99
Q

Why are pollution permits tradable

A
  • So firms can buy and sell the allowances between themselves
  • Any surplus on their permit can be traded
100
Q

How were tradable pollution permits given before the scheme

A
  • The permits were given free to the industry

* They were allocated on the basis of the amount of pollution created

101
Q

How much of carbon permits are retained by national governments

A

•They are able to retain up to 10% of carbon permits

They can offer them for sale depending on the level of scarcity

102
Q

How does the ETS reduce carbon emissions

A
  • They give incentives to firms to invest in clean technology
  • This reduces carbon emissions in the long run
103
Q

Why are carbon permits reserved

A
  • To enable new firms to enter the industries within the trading scheme
  • Firms can invest in schemes that reduce carbon emissions outside the EU
104
Q

Disdvantages of tradable pollution permits(FUC DIE)

FUC

A
  • Firms may pass costs of purchasing pollution permits to consumers
  • This leads to higher prices of commodities
  • E.g electricity
  • This is likely if demand is price inelastic
105
Q

Disadvantages of tradable pollution permits(FUC DIE)

FUC

A
  • Unintended consequences may occur
  • E.g less pressure on major polluting firms to clean up their act if they can buy extra permits elsewhere
  • Firms may relocate outside of the EU to reduce production costs
106
Q

Disadvantages of tradable pollution permits(FUC DIE)

FUC

A

Cost to government of monitoring pollution emissions from many companies within the scheme

107
Q

Disadvantages of tradable pollution permits(FUC DIE)

DIE

A
  • Disputes have arisen over allocation of carbon permits to firms
  • Some companies believe they should receive larger allowances
  • Some companies have taken legal action against the EC
108
Q

Disadvantages of tradable pollution permits(FUC DIE)

DIE

A
  • Information gaps may cause the EC to issue too many carbon permits
  • This means there is little incentive for firms to reduce pollution
  • Information gaps may also cause the EC to issue to little carbon permits
  • This means production costs for EU firms rise rapidly
  • This reduces their international competitiveness
109
Q

Disadvantages of tradable pollution permits(FUC DIE)

DIE

A
  • EU is just one part of the world

* Unless all countries engage in a similar scheme global emissions will continue to increase

110
Q

Advantages of tradable pollution permits(PEN FAP)

PEN

A
  • Pollution permits can be reduced over time as a part of a coordinated plan
  • E.g in 2008 EC cut carbon allocations by 5%
111
Q

Advantages of tradable pollution permits(PEN FAP)

PEN

A
  • ETS may act as a foundation for a global-wide scheme

* It has attracted interest from developed countries outside of the EU

112
Q

Advantages of tradable pollution permits(PEN FAP)

PEN

A
  • National governments can raise funds by selling their reserve permits to the industry
  • The revenue could be used to clean up the environment or compensate victims
113
Q

Advantages of tradable pollution permits(PEN FAP)

FAP

A
  • Firms have an incentive to invest in clean technology

* Firms are able to bank their excess pollution permits for use in future years

114
Q

Advantages of tradable pollution permits(PEN FAP)

FAP

A
  • A market is created for buying and selling carbon permits

* In effect the price mechanism can internalise the external costs associated with carbon emissions

115
Q

Advantages of tradable pollution permits(PEN FAP)

FAP

A
  • Production costs will increase for firms that exceed their pollution allowances
  • This is because they have to purchase additional permits
  • This provides a source of revenue for cleaner firms that can sell their excess pollution permits
116
Q

What is the purpose of state provision of information

RED

A
  • Reminds and notifies people of laws for their own protection
  • E.g seatbelts in motor vehicles
  • E.g not consuming alcohol while driving
117
Q

What is the purpose of state provision of information

RED

A
  • Encourages production/consumption of underprovided goods and services that have benefits
  • E.g pensions that yield long-term benefits
  • E.g healthy goods such as fruit
118
Q

What is the purpose of state provision of information

RED

A
  • Discourages production/consumption of overprovided goods and services that have costs
  • E.g unhealthy goods such as alcohol
119
Q

Define regulation

A
  • Government rules in markets to influence behaviour of consumers and producers
  • E.g Environmental Protection Act
120
Q

What is the Environmental Protection Act

A
  • Minimum environmental standards for emissions were set
