Market Failure Flashcards
Allocative efficiency
Efficient allocation of resources
MSB=MPB = MSC=MPC
Maximisation of society surplus
Maximisation of net social benefit
Resources perfectly follow consumer demand
Assumptions of allocative efficiency
Many buyers
No barriers to enter the market
Firms maximise profits
Consumers maximise utility
Public goods
Non-excludable-benefit of the good is not constrained to the person who pays for it. There is no cost efficient way of allocating price
Non-rival-the consumption of the good does not diminish the benefit for the next consumer
Examples-road signs, street loghts
Free rider problem and what it leads to
Consumers will not pay for the provision of the good as they will wait for others to pay, if no one pays there will be no incentive for firms as there is no profit so there will be market failure
Quasi public goods
Semi excludable and semi rival
Merit goods
Goods deemed more beneficial by consumers than they realise
Imperfect information-info failure:not clear, not there, ignore. Asymmetric information- information not passed down to consumer
Usually positive externalities in consumption
E.g. healthcare, education, exercise
MSB>MPB
Demerit goods
Goods that are deemed more harmful to the consumer than they realise
Imperfect information-info failure: not clear, not there or ignored. Assymetric info: information is there but it is not passed down to the consumer
Examples:smoking, alcohol, gambling
MPB>MSB
What is government failure and what does it lead to
Government failure is when the costs of intervention outweigh the benefits, leads to the worsening of the misallocation of resources and a greater welfare loss
Types of government failure
Valuing intervention
There may be information failure so it is difficult to allocate correct level of intervention
Costs of administration
-subsidies
-regulation
Unintended consequences:
Black markets
Employment
Inequality
Positive externalities in consumption
When there is a positive spill over effect to third parties from the actions of consumers
Examples are exercise, healthy diet and education
MSB>MPB
there is self interest- don’t consider full social benefit
There is an underconsumption of resources
There is a misallocation of resources
Positive externalities in production
When there is a positive spill over effect to third parties following the actions of producers
This could be training programmes at work or being more innovative
MPC>MSC
self interest from firms
Underconsumption/production
Misallocation of resources
Negative externalities in consumption
When there is a negative spill over effect to third parties from the actions of consumers
MSB<MPB
examples are poor diet, alcohol, smoking, gambling
There is self interest
A misallocation and overconsumption
Negative externalities in production
When there is a negative spill over effect to third parties following the actions of producers
Examples are air pollution, deforestation and depletion of resources
MSC>MPC
Overproduction
Self interest and misallocation of resources
Merit goods
Goods that are deemed more beneficial to consumers than they realise
This is due to imperfect information: information failure or asymmetric information
They are usually positive consumption externalities
MSB>MPB
Demerit goods
Goods that are deemed more harmful to consumers than they may realise
Imperfect information, most likely due to assymetric information
They are usually negative externalities in consumption
MPB>MSB
