Week 7 - Public Goods Flashcards
(78 cards)
`What makes a good nonexcludable?
A good is nonexcludable if people who don’t pay cannot be easily prevented from using it.
What makes a good nonrival?
A good is nonrival if one person’s use of it does not reduce the ability of another person to use the same good.
What is an example of a public good?
Asteroid deflection—nonexcludable and nonrival; everyone benefits without reducing others’ benefits.
What is an example of a private good?
A pair of jeans—excludable and rival; only one person can wear them, and nonpayers can be excluded.
What are the four types of goods based on excludability and rivalry?
Private goods – excludable and rival
Public goods – nonexcludable and nonrival
Club goods – excludable but nonrival
Common resources – nonexcludable but rival
Why can private goods be efficiently provided by the market?
Because they are excludable, people have incentive to pay, enabling market provision without inefficiency.
Why are public goods underprovided by the market?
They are nonexcludable, making it hard to get people to pay voluntarily.
What is a free rider?
Someone who enjoys the benefits of a public good without paying a share of the costs.
What is a forced rider?
Someone who pays a share of the costs of a public good but does not enjoy the benefits.
What’s the problem with free riders in public goods?
It leads to underprovision of the good, since people avoid paying, expecting others to bear the cost.
How can government solve the free rider problem?
By taxing everyone and using those funds to provide the public good.
What are club goods? Provide examples.
Excludable but nonrival goods, like television, music, and software.
Why can markets be inefficient in providing club goods?
People willing to pay cost may be excluded due to higher market prices.
What is a common resource?
A good that is nonexcludable but rival—use by one reduces availability to others.
What is the “tragedy of the commons”?
The tendency of unowned, nonexcludable resources to be overused and undermaintained.
Why are tuna not public goods?
Tuna are nonexcludable until caught, but rival—once consumed, others cannot use them.
What is the result of nonexcludability and rivalry in resources?
Overexploitation and undermaintenance of the resource.
How can norms help prevent the tragedy of the commons?
Groups enforce social norms to manage shared resources effectively—though harder with unrelated users.
What is an example of command and control to manage commons?
British Columbia limited fishing boats in 1968, but “capital stuffing” led to continued decline.
What is the takeaway about public goods and markets?
Public goods are valuable but underprovided by markets—nonexcludability is the key issue.
What are some solutions to the tragedy of the commons?
Social norms (Elinor Ostrom)
Private property rights
Command and control regulations
Individual Transferable Quotas (ITQs)
Cultural/religious constraints
What is the takeaway about common resources?
Nonexcludable but rival resources tend to be overused; solutions include property rights and social norms.
Public choice
the study of political behaviour using economic tools
What is rational ignorance?
whent he costs of being informed is more than the benefits of being informed
