Study Notes
The non-provision of public goods is a market failure where goods that are non-excludable and non-rivalrous are under-provided by the market due to the free-rider problem. This leads to missing markets and requires government intervention to ensure these goods are available at socially desirable levels.
- Public Goods — goods that are non-excludable and non-rivalrous. Example: National defense, flood defense systems.
- Private Goods — goods that are rival and excludable. Example: Private education, healthcare.
- Free-Rider Problem — occurs when individuals benefit from resources they do not pay for, leading to under-provision by the private sector. Example: Mosquito abatement programs.
- Positive Externalities — benefits that are enjoyed by third-parties as a result of an economic transaction. Example: Fruit consumption leading to higher productivity.
- Government Intervention — actions taken by the government to provide public goods and correct market failures. Example: Direct provision or contracting out to private firms.
