Common good (economics)

Under a common pool, Quasikollektivgut or impure public good (English common -pool resource or common good ) is understood in economics goods whose use is not exclusively or only with disproportionate effort and reigns in their use rivalry between users.

Examples of common goods are overcrowded public roads or fish stocks in waters with free access.

The term is derived from the commons, a collaborative form of farming. Commons are not necessarily common goods. Is access to a commons open and will not be sustained usage, it can be a commons for the common pool and so lead to the tragedy of the commons.
