Market Mechanism, Market Failure and Government Intervention in Markets Flashcards
signalling function of price
prices provide information to buyers and sellers ( so they can plan and coordinate their economic activity)
incentive function of price
prices create incentive to alter economic behaviour/activity e.g. high price firm incentivised to supply more
rationing function of prices
rising prices ration demand for product
allocative function of price
changing relative prices allocate scare resources away from markets which exhibit excess supply and into markets which there is excess demand
market failure
when the market mechanism leads to a misallocation of resources in the economy either completely failing to provide a good or service or providing the wrong quantity
complete market failure
a market fails to function at all and a ‘missing market’ results
partial market failure
a market does function but it delivers the wrong quantity of a good/service which results in a misallocation of resources
missing market
a situation in which there is no market because the function of prices have broke down.
private good
a good which is excludable and rivalrous e.g. a orange
excludable good
people who are unprepared to pay can be excluded from benefiting from the good
rival good
if one consumes the quantity available for others diminishes.
public good
a good that is non-rivalrous and non-excludable e.g. lighthouse, lighting.
quasi public good
a good which has features of both a public and private good e.g. partial excludability, partial rivalry, e.g. toll roads
externalities
a public good that is dumped on third parties outside the market
positive externalities
an external benefit that occurs when consumption or production of a good causes benefit to a third party e.g. when social benefit is greater tan private benefit.
negative externalities
an external cost that occurs when a good is produced or consumed causes cost to a third party e.g. where social cost is greater than private cost
