1.3.3 Public goods Flashcards
Public goods
goods which are both non-rivalrous and non-excludable
Non-excludability
The benefits derived from the consumption of a good cannot be solely to those who have paid for it.
E.G. fireworks
Non-rivalrous
The consumption of a good by one person doesn’t reduce the amount of availability for others.
E.G. Netflix
Free rider problem
•because public goods are non-excludable it’s difficult to charge people for benefiting once a product is available.
•The free rider problem leads to under provision of a good and thus causes market failure.
•free riders have no incentive to reveal how much they are willing and able to pay for a public good because they can enjoy the benefits without paying
Global public goods
these are goods which benefit every country, irrespective of which ones provide them.
E.G. security from war, violence, and crime, eradication of diseases
Quasi-public goods
A good which has some of the characteristics of a public good
Semi non-rivalrous: more consumers using a park beach or road reduce the space available for others as eventually they become crowded
semi non-excludable it’s possible but difficult or costly to exclude non-paying consumers
E.G. fencing a park or beach and charging an entrance fee
Tragedy of the commons
when no one owns a resource, it may get overused – people use and benefit from a common resource without regard to the effects on others. Overuse of a renewable resource can lead to a long-term decline in maximum sustainable yield.
E.G. fish stocks and deforestation
