Non-excludable good

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Non-excludable goods are defined in economics as goods or service whereby it is impossible to prevent an individual who does not pay for that thing from enjoying the benefits of it.

[edit] Examples

A well-architected building, such as the Eiffel Tower, creates an aesthetic good, which can be enjoyed by anyone who happens to look at it. It is difficult to prevent people from gaining this benefit (although people have tried, by forbidding amateurs from taking photographs of certain sites [1])

An idea, such as turning a garbage bag into a raincoat, can be used by anyone who knows about it.
