Social welfare and Market Failure Flashcards
Maximisation of social welfare or a society’s welfare
welfare refers to the feeling of contentment or well-being from the production and consumption of goods and services.
maximisation occurs when the quantity of goods and services produced from scarce resources results in the achievement of production effiecncy and alloctive efficiency.
production efficieny
implies that resources are efficiently used in the production of goods and services. where ac is minimised/lowest where mc intersects ac.
if production (in)efficiency is not achieved welfare loss occurs
allocative efficiency
implies that goods and services which consumers desire are neither underproduced nor overproduced.
overproduction (surpluses) or underproduction (shortage) results in a reudction in welfare or loss of welfare
third party
defined as those who are neither consumers nor producers of a good or service in a particular market.
merit goods and services
those where the social benefit exceeds the private benefit
usually underproduced by producers, so the government takes responsibilty for the provision of these goods.
healthcare(coach), eduaction (vet)
demerit goods
where the social cost exceeds the private cost.
cigarettes- second hand smoking addiction, alcohol indirect taxes implented by the goveernent to discourage the use of these overproduced goods
What is market failure?
is the inability of the market to allocate resources efficiently to maximise the welfare of society. This occurs when the quantity of a good or service produced in a market is not productively or allocatively efficient
causes of market failure
- monopoly
- postive or negative externalities
- non-provision of public goods and services
as long as externalities EXSIST
allocative efficiency will not be achieved and market failure will occur.
monopoly
monopolies have control over prices and output, therefore they can restrict output (underproduce) causing the market price to rise (overprice)
non-rivalrous and non-excludable
it can be consumed by more than one person without affecting its availability to other consumers
that consumers use the good or service without paying for it, can use the good without income as a factor
public goods and merit goods cause market failure because
these goods or services cannot be provided accurately by the market mechanism (interactions of demand and supply) as they result in free riders. FREE RIDERS ARE INDIVIDUALS WHO CONSUME GOODS AND SERVICES FREE CHARGE. Therefore, private firms are unwilling to produce these goods as such resources are not allocated to their production.
positive externalities
the benefits incurred by a third party from the consumption or production of a good or service by an individual
healthcare public good and merit goods
negative externalities
disadvantages or costs incurred by a third party from the consumption or production of a good or service by an individual
alcohol- demerit good private good
negative and postive externalities cause market failure because
the market mechanism ignores externalities. As such goods which generate positive externalities are overpriced and underproduced. While goods that generate negative externalities are underpriced and overproduced.
