Unit 5 Flashcards
Positive Externality
Underproduction of output and therefore under-allocation of resources
Negative Externality
Overproduction of output and therefore overallocation of resources
Ways to correct negative externality
1) Private bargaining
2) Liability rules and lawsuits
3) Tax on producers
4) Direct controls
5) Market for externality rights
Ways to correct positive externality
1) Private bargaining
2) Subsidy to consumers
3) Subsidy to producers
4) Government provision
Moral Hazard Problem
the tendency of one party to a contract or agreement to alter his or her behavior
Adverse selection
One person knows something that the other does not
Assymetric information
Buyers and sellers do not have the same information
The study of market failures helps us
understand how regulating markets may help with the allocation of resources
study of government failure may help us to
understand how changes in the way the government functions may help to operate more efficiently
Demand-side market failures
demand curves do not reflect consumers full willingness to pay
Supply-side market failures
Supply curves do not reflect full cost of production
Allocation efficiency
mb=mc
Total surplus is at a maximum
Maximum willingness to pay=minimum acceptable price
Private goods
Cars, clothes, computers, etc.
- Rivalry-when one person buys and consumes a product it is no longer available for another person
- Excludability- sellers can keep people who do not pay for a service from obtaining the benefits
Public goods
Nonrivalry and nonexcludability
-leeds to a free rider problem- once a producer has provided a public good, everyone obtains the benefit
The more free riding the
less the demand
Cost benefit analysis
Comparison of mb and mc to figure out whether or not to provide or how much to provide of a service
Quasi-public good
exclusion is possible ie. education, streets, libraries etc.
(provided by the government through taxes)
