5- The Market Mechanism, Market Failure And Government Intervention Flashcards
What is a free market?
Market with no government intervention
How does the economy allocate resources effectively?
The price mechanism is used to allocate resources effectively. The price mechanism consists of
- rationing function
- incentive function
- signalling function
Define what market failure is?
Market failure
- occurs when the free market, left alone, fails to deliver an efficient allocation (productive and allocative efficiency) of resources and so results in the loss of economic welfare and leads to economic inefficiency.
When price is too high or too low
Complete market failure results in a missing market.
Define what a missing market is?
Missing market
- is a situation in which there is no market for a good because prices have broken down
Partial market failure is mire common. Define what partial market failure is?
Partial market failure
- is where a market exists but contributes to misallocation of resources and so does not maximise economic welfare
What are the main causes of market failure?
1) positive and negative externalities
2) merit and demerit good
3) public goods
4) monopoly and other market imperfections
5) inequalities in the distribution of income and wealth
6) factor immobility causing unemployment
7) imperfect information
Define what public goods are?
Public goods - a good that possesses the characteristics of: > non- excludability > non- rivalry > non- rejectablilty .. inconsumption
Define what non-excludable means?
Non- excludable-
Once provided, no person can be excluded from benefitting
Define what non-rivalry means?
Non-rivalry
- consumption of the good by one person does not reduce the amount available for consumption by another person
Define what non-rejectable means?
Non- rejectable
- when a public good is provided, you cannot reject it
Examples of public goods?
- traffic lights
- defence
- clean air
- environmental goods
- public service broadcasting
Define what a quasi-public good is?
Quasi-public good
- a good that has some of the qualities of a public good but does not fully possess one or two required characteristics of non-rivalry, non-excludability, non-rejectability
Examples of quasi-public goods?
Beaches
Park
Open wifi networks
Define what a private good is?
Private good
- a good that is both excludable and rival in consumption
Define what a free rider is?
Free rider
- a person or organisation which receives benefits that others have paid for without making any contribution themselves
How do public goods lead to market failure?
If the market mechanism is used to provide public goods, there will be market failure (and so a missing market) because of the free rider problem
> consumers have no incentive to pay for it nor it is possible to force them
> producers don’t have the incentive to supply as they won’t get much profits in supplying it
And so therefore there will be a missing market- where there is a need for a product or service- and so market failure
This is why the government/state provides public goods
What type of government intervention can solve the free rider problem and prevent market failure?
State Provision
> used for public goods otherwise problem of free riders. And/or deals with inequality eg education>private
schools only rich would be able to afford it
Analysis:
One way to prevent free rider problem is to have government intervention. State provision
Evaluation of using state provision as a form of government intervention?
Evaluation of state provision
- Expensive, there are opportunity costs
- government is not driven by the profit motive and so goods/services may not be best quality, innovated etc
- overconsumption
- how much to produce- imperfect information
- political bias
Define what externalities are?
Externalities
- costs or benefits that spill over to third parties external to a market transaction
Define what positive externalities are?
Positive externality
- a positive spill over effect to third parties of a market transaction
Social benefits exceed private benefits
Define what negative externalities are?
Negative externality
- a negative spillover effect to third parties of a market transaction
Socials costs exceed private costs
Define
- marginal private cost
- marginal external cost
- marginal social cost
Marginal private cost
- the cost to an individual or firm of an economic transaction
Marginal external cost
- the spillover cost to third parties of an economic transaction
Marginal social cost
- the full cost to society of an economic transaction, including private and external cost
MSC= MPC+ MEC
Define
- marginal private benefit
- marginal external benefit
- marginal social benefit
Marginal private benefit
- the benefit to an individual or firm of an economic transaction
Marginal external benefit
- the spillover benefit to third parties of an economic transaction
Marginal social benefit
- the full benefit of an economic transaction, including private and external benefits
MSB=MPB+MEB
Define merit goods?
A good that would be under consumed/ underprovided in a free market, as individuals do not fully perceive the benefits obtained from consumption
- ought to be subsidised or provided free at the point of use or funded by government
- society values and judges that everyone should have them regardless of whether an individual wants them
Define a demerit goods?
A good that would be overconsumed/overprovided in a free market, as it brings less overall benefit to consumers than they realise
- consumption leads to negative externalities
- consumers unaware of negative externalities because they have information failure- imperfect info
- consumers underestimate long run costs to themselves of consuming demerit goods
Define subsidy?
Subsidy is money given to firms or individuals from government to lower costs of production and increase supply
Define taxation?
A means by which governments finance their expenditure by imposing charges on citizens and corporate entities. Governments use taxation to encourage or discourage certain economic decisions.
Define direct taxation?
A direct tax is paid directly by an individual or organization to an imposing entity
- tax on income
- used more to redistribute income and wealth.
Define indirect taxes?
the levying of tax on goods and services rather than income or profits.
- tax on spending
- taxes on suppliers which affects costs of production
- taxes on specific kind of consumer spending eg excise duties on cigarettes, alcohol, petrol and VAT
- PRODUCERS pay the indirect tax eg VAT not consumers. Producers have the ability to pass on the tax to consumers. Its good or service is elastic its easy to pass on
Analysis of using taxation to prevent market failure?
- taxes (on producer) of negative externalities
- if government levied a tax on producer of P1- P2, this would increase the costs of production of firms
- (firms would internalise the external costs of the good)
- this would result in a shift to the left in supply from S-S1
- Price would rise from P- P1
- consumption will fall to the socially optimal level of Q1
Evaluation if tax on producers to prevent market failure?
- blck market
- success/ effectiveness depends on the size of tax
- taxes costly to implement, monitor
- look at elasticities
- taxes will cause inequality
- difficult to measure the level of negative externalities
- government may increase tax revenue, reducing budget deficit, but consumption may not fall as much as desired
How does a demerit good lead to market failure?
A demerit good may be over consumed/overprovided because consumers only consider the private costs so the negative externalities are not taken into account. MPC is less than MSC and the level of consumption ends up below the socially optimal level
How does a merit good lead to market failure?
A merit good is a good that is underconsumed/ underprovided in a free market because consumers only consider the private benefits, MPB, so the positive externalities are not taken into account. MPB is less than the MSB and the level of consumption ends up below the socially optimal level
> there is also greater consumer surplus
Analysis of subsidising producers?
- when you subsidise producers you give a sum of money for each unit produced, thus lowering costs of supply
- supply shifts right, lowers price p-p1
- consumption increases social optimal level
- if supply increases, there is an extension in demand
- consumption increases
Evaluation of subsidy?
- size of subsidy- greater subsidy, the more shift, cheaper, the more increase in consumption
- PES
- costly, expensive, opportunity costs
- does not encourage innovation, increases in productivity, efficiency
Define regulations and legislations?
Analysis?
Evaluation?
Legislation- law
Regulation- organisations which make sure the industry complies with legislation
One way gov inter. is L&R. Give specific example. Show shift
Evaluation
- black market
- expensive to implement/ police, opportunity costs
- elasticities
- only effective if there are effective consequences- must be substantial(worth) but that itself is also costly
- requires strict supervision
Define
- symmetric information?
- asymmetric information?
- imperfect information?
Symmetric information
- is when both the seller and the buyer are well informed about the goods and services and prices in the market
- if information is imperfect, then it will not be possible to make rational decisions and so market failure will occur
Asymmetric information
- is when either the seller or buyer has more information than the other party in a transaction
- the extra information means that they have additional bargaining power that can lead to non-rational decisions by the other party
Also can lead to incorrect policies and incorrect judgements
Imperfect information
- incomplete on incorrect information
Eg of gov intervention - advertisment
How does immobility of factors of production lead to market failure?
- The market assumes that resources (factors of production) move automatically to where they are needed most
»» eg if pears are more popular apples, then the higher prices of pears will attract resources away from apples supply, which now offers a lower reward - this theory relies on perfect mobility of labour- meaning factors of production can easily shift from one use to another
- if immobility of factors of production exists, then factors of production do not easily transfer to different uses. This means that the market does not produce the desired market equilibrium and so market failure occurs
Immobility takes place in two forms. What are they?
Geographical immobility
- where the resources cannot easily move from one geographical area to another
Occupational immobility
- where the resources cannot easily move from a particular use or job to another
Immobility of factors of production- Labour?
Occupational immobility of labour-
- as patterns of demand and unemployment change, many workers may find it difficult to easily secure new jobs, since they may lack necessary skills
Geographical
- where workers find it difficult to move where employment opportunities maybe due to family ties and differences in housing costs
Monopoly and market failure?
- restrict supply
- increases prices
- (as demand is price inelastic, total rev will increase)
- TC will be lower as fewer products are produced so the monopolies make higher profits
- the monopolist has benefitted but at the expense of the consumers- fewer consumers now have the product and they are paying a higher price
- miss allocation of resources
Possible intervention when monopolies cause market failure?
- regulation
- max price
- tax
Define
- income
- wealth
Income
- is a flow of money received over a period of time, such as annual wages
Wealth
- is a stock of assets accumulated over time, such as ownership of property and cash balances held in the banking system
Why does inequalities in the distribution of income and wealth lead to market failure?
- The market mechanism operates on the basis of people offering their skills in return for financial rewards. As skills differ, incomes vary and so inequality. Wealth is also influenced by inheritance
- market failure because people on low incomes satisfy fewer wants, cannot benefit from merit goods whereas higher income people can satisfy less vital wants therefore misallocation of resources
- however, the extent to which an economy should create a more even distribution of income and wealth is a value judgement. A lot of measures would need to put in place to know how much… is needed - costly
Argument for the free market?
- the free market is one where there is minimal government intervention
- we believe that the free market generally works to allocate resources effectively
- it results in more competition, greater choice, lower price and better quality goods
- goods are allocated via the market mechanism
- supply and demand determines the prices of good and this in turn dictates the quantity that is sold
- when prices rise, consumers ration their consumption and less is consumed
- a new equilibrium arises
- 1 line to state how the market in context would be good with no intervention
- HOWEVER, market failures
