Public good
Meaning in economics, with examples
In economics, public good means: A good that people cannot easily be stopped from using and whose use by one person does not reduce what is left for others, such as street lighting.
In Turkish: kamu malı
How it is used
Economists call these two features non-excludable and non-rival. Because people can enjoy public goods without paying (the free-rider problem), markets provide too little of them, so they are usually paid for through taxes. Examples: national defence, lighthouses, public health research.
Example sentences
National defence is a classic public good: protecting one citizen protects everyone.
Because of free riders, private firms rarely supply public goods such as flood defences.
Common collocations
- provide public goods
- a pure public good

- the free-rider problem
