- Non-excludability
- Non-excludability means it is costly or impossible to exclude someone from using the good, whether or not they have paid for it.
Example
Can you think of an example of non-excludability?
Police patrols cannot easily protect some houses in a street from burglary while leaving their neighbours unprotected. Protecting some necessarily means protecting the others too.
Test yourself
Can you name the two tests of a public good, and the two ideas built on them?
