3.1.5 - Market Mechanism, Market Failure, Gov. Intervention Flashcards

1
Q

Define price mechanism

A

a system where forces of demand and supply determines the prices or commodities and their changes
(Way that basic economic problem is resolved in a market economy)

Coined the ‘invisible hand of the market’ by Adam Smith

Q

What 3 functions does the price mechanism use

A
  1. Rationing;
    When there are scarce resources, price increases which discourages demand
  2. Incentive;
    Encourages change in behaviour of a consumer or a producer
    High prices encourage firms to supply more to a market
  3. Signalling;
    Price acts as a signal to consumers and new firms entering the market
    HIGH PRICE signifies PROFITABILITY which encourages reduced demand — consumers leave markwr

A

Occurs whenever market leads to a misallocation of resources in the economy

2 types:

  1. Complete
    Market doesn’t exist, missing
  2. Partial
    Market exists but contributes to resource misallocation

Q

What is a public good?

A

Commodity / service made available to all members of society

Characteristics include:

  • non-excludability:
    Free riders
  • non-rival consumption:
    Each parties consumption of the food doesn’t compromise others enjoyment
  • non-rejectable:
    Collective supply of a pure public good where it can’t be rejected by people

Examples include flood defence, public service broadcasting, sanitation infrastructure

Q

What is a quasi-public good?

A

Near public good

Characteristics include:

  • semi non-rival
    Up to an extent, more consumers using a park, beach, road etc do not not reduce space available for others (eventually things get crowded)
  • semi non-excludable
    It is possible but not easy or cheap to exclude non-paying customers

Type of external benefit (public good) or external cost (public bad) which is dumped on third parties outside the market

Positive:
- early years education
- free school
- museums / galleries

Negative:
- noise pollution

Q

Define a merit good, provide 2 of its characteristics and give an example

A

Goods for which the social benefits of consumption exceed the private benefits

Characteristics:
- excludable
- rivalrous

Governments believe these will be under-consumed and so should be subsidised or provide free at the point of use

i.e educations, vaccinations

Under provision may result from imperfect info

Q

What is a demerit good?

A

Goods for which the social costs of consumption exceed the private costs (goods are subject to negative externalities in consumption)

Over provision of demerit goods may result from imperfect information

i.e tobacco, alcohol

Q

Why would geographical and occupational immobility lead to market failure?

A

Geographical immobility:

When workers find it impossible or difficult to move to other parts of the country / countries

Occupational immobility:
When workers find it impossible or difficult to move between jobs because they lack skills required for new jobs

Both could lead to unemployment and a waste of scarce resources
Contributes to market failure

Q

In what ways can methods of gov intervention be assessed?

A
  • impact of alternative policies on different groups
    I.e producers and consumers
  • financial and opportunity cost of alternative policies
  • effects of intervention on equity and efficiency
  • significance of elasticity on the method
30
Q

2 types of taxation?

A
  1. Indirect:
    Tax levied on goods and service I.e VAT
  2. Direct:
    Tax levied on incomes of firms and people I.e income tax
31
Q

(Gov intervention) Advantages and disadvantages of taxation?

A

Advantages:

  • reduces production and consumption of demerit goods and those with negative externalities
  • raises revenue to fund merit and public goods
  • market orientated solution

Disadvantages:

  • ineffective if PED for product / service is inelastic
  • inefficiencies may occur — costs to collect tax
  • tax evasion
32
Q

Simply define subsidy, and who can they be for?

A

Payment from government
to:

  1. Producers:
    For each unit of good they produce
    I.e bus payments
  2. Consumers
    I.e over 60s winter fuel
33
Q

(Gov intervention) Advantages and disadvantages of subsidies

A

Advantages:

  • encourages consumption and production of merit goods with positive externalities
  • purpose is to increase real income of consumers by keeping prices below market equilibrium

Disadvantages:

  • inefficiency
  • cost and opportunity cost
34
Q

(Gov intervention) Advantages and disadvantages of regulation, standards and legal control

A

Advantages:

  • forces consumers to consume more merit goods
  • can be cheap and easy to impose
  • backed by fines

Disadvantages:

  • cost of enforcement
  • opportunity cost
  • black markets can develop
35
Q

(Gov intervention) advantages and disadvantages of information provision

A

Advantages:

  • move towards free market approach
  • provides info needed to maximise welfare

Disadvantages:

  • cost and opportunity cost
  • may be ineffective, often ignored
  • may not reach target audience
36
Q

Define price ceiling

A

Maximum price laws set, illegal to sell below the price i.e rent prices

37
Q

Define price floor

A

Minimum legal prices where it’s illegal to sell below it when trading i.e EU agricultural prices

38
Q

What does Polluter Pays Principle mean?

A

Producer is responsible for paying for damage done to the environment

Underpins environmental policy

Traceable pollution permits allow owners to emit certain amounts of pollution

39
Q

What is the state provision of goods?

A

Governments provide public goods which are under provided in the free market i.e education, healthcare

These make merit goods more accessible, might increase their consumption and yield positive externalities

Could be expensive

40
Q

What is a private good?

A

A private good is a product that must be purchased to be consumed, and consumption by one individual prevents another individual from consuming it.

I.e dinner at a restaurant

41
Q

How can public goods lead to market failure?

A

If some consumers decide not to pay but use the good anyway — leads to underfunding

42
Q

How can externalities lead to market failure?

A

When the good / services price equilibrium doesn’t accurately reflect the true costs and benefits of that product / service

The market will fail by not supplying the socially optimal amount of the good. The imbalance causes allocative inefficiency, which is the over- or under-consumption of the good.

43
Q

How can merit goods lead to market failure?

A

In the free market they are provided at a quantity below the socially optimum level thus creating market failure as there is a misallocation of resources

44
Q

How can demerit goods lead to market failure?

A

In the free market these goods are over consumed — prices rise to in theory to deter buyers

45
Q

How can a monopoly cause market failure?

A

Because not enough of a good / service is available or the price gets too high

46
Q

How can income inequality lead to market failure?

A

Only products and activities that create profits are manufactured or pursued. This causes a large portion of consumers to be excluded from the market because they lack the income to purchase these products

47
Q

How can governments influence the allocation of resources?

A
  • public expenditure
  • taxation
  • regulation
48
Q

When does government failure occur?

A

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

Potential sources include:
- inadequate information
- conflicting objectives
- administrative costs

Gov intervention can lead to unintended consequences

49
Q

What are the types of market failure?

A
  1. externalities
    Negative externalities are caused by consumption of demerit goods, i.e cigarettes
  2. under provision of public goods
    Public goods are non-excludable and non-rival. They are under-provided in a free market because of the free-rider problem
  3. information gaps
    Imperfect / asymmetric info leads to a misallocation of resources
  4. monopolies
    Consumers are often overcharged leading to underconsumption of the good / service (therefore needs and wants aren’t fully met)
  5. inequalities in the distribution of income and wealth
    Can lead to negative externalities I.e social unrest
50
Q

Define symmetric information

A

Consumers and producers have perfect market information to make their decision leading to an efficient allocation of resources

51
Q

Define asymmetric information

A

Unequal knowledge between consumers and producers leading to a misallocation of resources, hence market failure

52
Q

What is the principal-agent problem?

A

When the agent makes decisions for the principal, but the agent is inclined to act in their own interest rather than those of the principal I.e shareholders and managers having different objectives

53
Q

Define mobility of Labour

A

The ability of workers to change between jobs
> unemployment is evidence that labour markets don’t work efficiently

54
Q

What is frictional unemployment?

A

When people are in-between jobs and are in search of a new one

55
Q

What is structural unemployment?

A

Occurs when there is a decline in an industry, meaning worker skills don’t match the location and skills required for the job

56
Q

What does geographical immobility of FOP refer to?

A

Obstacles which prevent FOP moving between areas I.e Labour finding it hard to find work due to family ties etc

57
Q

What does occupational immobility of FOP refer to?

A

Obstacles which prevent FOP changing their use i.e Labour finding it hard to change their occupation m

58
Q

Why would the government impose taxes i.e ad valorem tax on demerit goods like cigarettes?

A

To discourage consumption of the demerit good and reduce negative externalities.

For price inelastic goods like cigarettes most of the burden of tax is placed on the consumer

59
Q

What are specific taxes?

A

Set taxes per unit

60
Q

What does it mean for a firm to internalise an externality?

A

The polluter pays for the damage.

Increased prices of goods, whereby tax is equal to the external cost of each unit, then the supply curve becomes MSC rather than MPC, therefore the free market equilibrium becomes the socially optimum equilibrium

61
Q

Do consumers gain more or less from price elastic or inelastic subsidies?

A

Consumers gain more when demand is price inelastic, whilst producers supply more when demand is price elastic

62
Q

What is a maximum price?

A

Where the consumption or production of a good is to be encouraged — so the good doesn’t become too expensive to produce or consumer
>have to be set below free market price

SAME AS PRICE CEILING

63
Q

What are price ceilings good for consumers?

A

It prevents monopolies exploiting consumers i.e price caps on roaming charges in the EU

Could lead to welfare gains for consumers by keeping prices low

Could increase efficiency in firms

64
Q

What is a minimum price?

A

Where consumption or production of a good is discouraged. It ensures the good never falls below a certain price I.e alcohol

> makes goods less affordable hence reducing negative externalities from consumption

Have to be set above the free market price otherwise they would be ineffective

65
Q

What does a tradeable pollution permit do?

A
  • limits the amount of negative externalities, in the form of pollution, created in industries

> firms can buy and sell surplus allowances among themselves

66
Q

Advantages of a tradeable pollution permit?

A
  • should be a benefit in the long run by encouraging firms to use green production methods
  • Gov can raise revenue from permits
  • greener firms can raise revenue
67
Q

Disadvantages of a tradeable pollution permit?

A
  • could lead to some firms relocating to where they can pollute without limits, which will reduce their production costs
  • firms might pass higher costs onto consumers
  • competition could be restricted in the market (barrier to entry)
  • could be expensive for governments to monitor emissions
68
Q

Why would governments want to implement information provision?

A

To ensure there is no information failure and so consumers and firms can make informed economic decisions

69
Q

What are 4 causes of government failure?

A
  1. Distortion of price signals
    - Gov subsidies could distort price signals by distorting the free market mechanism.
  2. Unintended consequences
    - When actions of producers and consumers have unexpected or unintended consequences
  3. Excessive administrative costs
    - The social benefits of a policy might not be worth the financial cost of administering the policy.
  4. Information gaps
    - Some policies might be decided without perfect information I.e gov housing policies which failed
70
Q

What is a public bad?

A

Opposite of a public good
> provides dis utility or dissatisfaction to people when consumed
> reduces welfare
