A classic example of the inefficiency caused by non-excludability is the tragedy of the commons (which Hardin, the author, later corrected to the 'tragedy of the unmanaged commons' because it is based on the notion of an entirely rule-less resource) where a shared, non-excludable, resource becomes subject to over-use and over-consumption, which ...
However, some theorists, such as Inge Kaul, use the term "global public good" for a public good that is non-rivalrous and non-excludable throughout the whole world, as opposed to a public good that exists in just one national area. Knowledge has been argued as an example of a global public good, [4] but also as a commons, the knowledge commons ...
Wild fish are an example of common goods. They are non-excludable, as it is impossible to prevent people from catching fish. They are, however, rivalrous, as the same fish cannot be caught more than once. Common goods (also called common-pool resources [1]) are defined in economics as goods that are rivalrous and non-excludable. Thus, they ...
Club goods (also artificially scarce goods, toll goods, collective goods or quasi-public goods) are a type of good in economics, [1] sometimes classified as a subtype of public goods that are excludable but non-rivalrous, at least until reaching a point where congestion occurs. Often these goods exhibit high excludability, but at the same time ...
The additional definition matrix shows the four common categories alongside providing some examples of fully excludable goods, Semi-excludable goods and fully non-excludeable goods. Semi-excludable goods can be considered goods or services that a mostly successful in excluding non-paying customer, but are still able to be consumed by non-paying ...
The free-rider problem is common with public goods which are non-excludable and non-rivalrous. Non-excludable means that non-payers cannot be stopped from getting use of or benefits from the good. Non-rival consumption stipulates that the use of a good or service by one consumer does not reduce its availability for another consumer.
This 2019 Wikimania submission discusses how the concept of a public good has evolved into that of a digital public good: . A public good is a good that is both non-excludable (no one can be prevented from consuming this good) and non-rivalrous (the consumption of this good by anyone does not reduce the quantity available to others).
In economics, open access resources are, for the most part, rivalrous, non-excludable goods. This makes them similar to common goods during times of prosperity. Unlike many common goods, open access goods require little oversight or may be difficult to restrict access. [5]
