a concentration ratio
measures the combines market share of the largest firms in a particular market
four firm concentration ratio
measures the combined market share of the four largest firms in a particular market
what are three benfits from monopoly
internal economies of scale leading to lower prices
greater innovation
more choice
the rationing function of price
arises because its not possible to satisfy unlimited wants of consumers with the scarce resources available
price acts as a rationing act as only consumers are prepared to pay the market price are able to purchase it, if a good becomes scarce then the price will rise discouraging buyers so preserving stocks
the signalling function of price
referees to the importance of price in helping buyers and sellers make discussions about wether its worthwhile to buy or sell a product.
the incentive function of price
refures to the way in which low prices act as an incentive for consumers to buy more of a product in order increase their satisfaction
while high prices act as an incentive for suppliers to supply more in order to maximise profit.
market failure
occurs when a market economy does not achieve an efficient allocation of resources
what are the three main ways an economy can be organised in?
market economy - all goods and services are provide through the interaction of demand and supply
- a planned or commanded economy - decisions are made by the government
-a mixed economy - some goods and services are provided through a market economy and some are provided through government planning.
productive efficiency
firms producing at the lowest possible average costs
allocative efficiency
goods produced by an economy finding their way to the consumers who get the greatest welfare from those goods.
misallocation of resources
occurs when an economy fails to produce goods at the lowest average total costs and fails to achieve the goal of providing those goods to the consumers whom they provide the greatest welfare.
complete market failure
occurs when a good or service is not supplied at all
partial market failure
occurs when a market exists but where the level of production is too high or too low
externalities
are the effect of economic activity on third parties who have no had any say in this activity taking place
positive externality
benefits to a third party, can be passed on due to either the consumption or the production of a commodity by other members of society
negative externality
problems experienced by a third party
merit goods
a good that is underproduced in a pure market economy
demerit good
decibes a good that is over produced in a pure market economy
three main market imperfections that can cause market failure
-monopoly power
-imperfect information
-immobility of factors of production
rivalry (diminishability)
feature of a good or service that if a person consumed a quantity of that then it would not be avaliable to others
