The Market Mechanism, Market Failure and Government Intervention in Markets Flashcards

1
Q

Rationing function

A

When there are scarce resources, price increases due to the excess of
demand. The increase in price discourages demand and consequently rations
resources. e.g. plane tickets

Q

Signalling function

A

The market price sends signals to buyers and sellers that help to determine their economic behaviour. An increase in demand (a shift to the right) leading to a higher equilibrium price sends a signal to producers to increase the quantity supplied and vice versa for a fall in demand. A rise in supply (a shift to the right) leading to lower equilibrium price sends a signal to buyers to increase the quantity demanded and again vice versa for a fall in supply.

Q

Partial market failure

A

occurs when the market produces a good, but it is the wrong quantity or the wrong price. Resources are misallocated where there is partial market failure.

Q

Types of market failure

A
  • Externalities (consumption of demerit goods)
  • Public goods (Public goods are non-excludable and non-rival, and they are underprovided in a free market because of the free-rider problem)
  • Inequalities in the distribution of income and wealth (This can lead to negative externalities, such as social unrest)
  • Monopoly (Since the consumer has very little choice where to buy the goods and services offered by a monopoly, they are often overcharged. This leads to the underconsumption of the good or service, and therefore there is a misallocation of
    resources, since consumer needs and wants are not fully met)
  • Imperfect information (misallocation of resources)

Q

Quasi public good

A

They are partially provided by the free market. For example, roads are
semi-excludable, through tolls and they are semi-non-rival.

Q

The free-rider problem

A

Since public goods are non-excludable (lack of property rights), consumers have an incentive not to contribute to the costs of their provision. This is because they receive the benefit of the good whether they contribute or not.

Q

The Tragedy of the Commons

A

A situation in which individuals with access to a public resource (also called a common) act in their own interest and, in doing so, ultimately deplete the resource.

Q

Why does the absence of property rights lead to externalities

A

Markets become inefficient, the moral hazard assumes someone else will pay the consequences for a poor
choice.

Q

Demerit goods

A

These are associated with
information failure, since consumers are not aware of the long run implications of
consuming the good, and they are usually overprovided. For example, cigarettes and
alcohol are demerit goods. The negative externality to third parties of consuming
cigarettes is second-hand smoke or passive smoking.

17
Q

Merit goods

A

These are associated with
information failure too, because consumers do not realise the long run benefits to
consuming the good. They are underprovided in a free market. For example,
education and healthcare are merit goods. The positive externality to third parties of
education is a higher skilled workforce.

18
Q

Why imperfect and asymmetric information can lead to market failure

A

It means that there cannot be an informed decision leading to a misallocation of resources, Consumers might pay too much or too little, and firms might produce the incorrect amount. For example, monopolies might exploit the consumer by charging them more than they need to.

19
Q

How a monopoly can lead to market failure

A

Monopolies could exploit the consumer by charging them higher prices.
This means the good is under-consumed, so consumer needs and wants are not fully
met.
This loss of allocative efficiency is a form of market failure.
Monopolies have no incentive to become more efficient, because they have few or
no competitors, so production costs are high.
There is a loss of consumer surplus and a gain of producer surplus.

20
Q

Immobility of factors of production can lead to market failure

A

Unemployment is evidence that labour markets do not work efficiently

21
Q

Principles of UK competition policy

A
  1. Enhancing competition between firms through promotion of small business
  2. Deregulation and privatisation- firms can compete in a competitive market, which should also help improve economic efficiency.
  3. Competitive tendering for government contracts- private firms operate things such as roads or hospital.
22
Q

Arguments for and against the public ownership of firms

A

Some nationalised industries yield strong positive externalities. For example, by
using public transport, congestion and pollution are reduced.
Nationalised industries have different objectives to privatised industries, which are
mainly profit driven. Social welfare might be a priority of a nationalised industry.
By nationalising an industry, natural monopolies are created. This is because it is
inefficient to have multiple sets of water pipes, for example. Therefore, only one
firm provides water.
Some nationalised ind

23
Q

Arguments for and against privatisation

A

Free market economists will argue that the private sector gives firms incentives to
operate efficiently, which increases economic welfare. This is because firms
operating on the free market have a profit incentive, which firms which are
nationalised do not.
Since they are operating on the free market, firms also have to produces the goods
and services consumers want. This increases allocative efficiency and might mean
goods and services are of a higher quality.
Competition might also result in lower prices.
By selling the asset, revenue is raised for the government. However, this is only a
one-off payment.

24
Q

The problem of regulatory capture

A

Where the regulator become overly sympahtetic to the firm it is regulating
e.g. OFGEM – UK regulator for gas and electricity markets. In early 2016, with falling gas wholesale prices, the big energy companies were able to increase their profit margins, equalt to £120 per customer.

25
Q

Government failure

A

When government intervention in the economy leads to a misallocation of resources

26
Q

Causes of government failure

A

Distortion of price signals
Unintended consequences
Excessive administrative costs
Information gaps
