Chapter 4 Market Failures: Public Goods and externalities
case theorem
private sector bargaining can solve externality problem government's role in correcting externalities
an example of a nonexludability is
street lighting, the police
private goods
- Produced in the market by firms - goods that are both excludable and rival in consumption - goods offered for sale Rivalry and Excludability
cost
- resources diverted from private good production - private goods that will not be produced
Quasi - Public Goods
-Could be provided through the market system -Because of positive externalities the government provides them -Examples are education, streets, museums
optimal reduction of an externality
-Officials must correctly identify the existence and cause - government failure may occur
demand-side market failures
-When it is not possible to charge consumers for the product -Some can enjoy benefits without paying -Firms not willing to produce since they cannot cover the costs
Non-rival
the consumption of the good by one person does not keep other people from also consuming that good.
consumer surplus
the difference between the highest price a consumer is willing to pay for a good or service and the actual price the consumer pays - extra benefit from paying less than the maximum price
government intervention
Correct negative externalities Direct controls pigovian tax Correct positive externalities Subsidies Government provision
free rider problem
For a group, the problem of people not joining because they can benefit from the group's activities without joining.
Market Failures
Markets fail to produce the right amount of the product
Resources may be
Over-allocated Under-allocated
Under allocated
The condition of resources when they are assigned to do less work than their normal work capacity.
over allocated
The condition of resources when they are assigned to do more work than is their normal work capacity
nonexcludability
The inability to keep nonpayers (free riders) from obtaining benefits from a certain good; a characteristic of a public good.
Supply-side market failures occur when:
a firm does not pay the full cost of producing its output
cost-benefit analysis
a study that compares the costs and benefits to society of providing a public good
public goods
are goods provided by government offered for free
Efficiently Functioning Markets
demand curve must reflect the consumers full willingness to pay and supply curve must reflect all the costs of production - benefit surpluses are maximized for consumers and producers
producer surplus
difference between the actual price a producer receives and the minimum price they would accept - extra benefit from receiving a higher price
in a supply-side market external costs of producing the
good are not reflected in supply
The Reallocation process
government - taxes individuals and businesses - takes the money and spends on production of public goods
Externalities
is the cost or benefit accruing to a third party external to the market transaction
Characteristics of public goods
nonrivalry nonexcludability free rider problem
benefit
the extra satisfaction from the output of more public goods
Excludability
the property of a good whereby a person can be prevented from using it ( you don't buy it, you can't get it)
positive externalities
too little is produced demand-side market failures
negative externalities
too much is produced supply side market failures
rivalry
when one person buys and consumes a product, it is not available for another person to buy and consume
