A good, service or resource that is unable to prevent or exclude non-paying consumers from experiencing or using it can be considered non-excludable. An architecturally pleasing building, such as Tower Bridge , creates an aesthetic non-excludable good, which can be enjoyed by anyone who happens to look at it.
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 ...
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 ...
A private good is defined in economics as "an item that yields positive benefits to people" [1] that is excludable, i.e. its owners can exercise private property rights, preventing those who have not paid for it from using the good or consuming its benefits; [2] and rivalrous, i.e. consumption by one necessarily prevents that of another.
A consumer good or "final good" is any item that is ultimately consumed, rather than used in the production of another good. For example, a microwave oven or a bicycle that is sold to a consumer is a final good or consumer good, but the components that are sold to be used in those goods are intermediate goods.
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 ...
Indeed, if non-payers can be excluded by some mechanism, the good may be transformed into a club good (e.g. if an overused, congested public road is converted to a toll road, or if a free public museum turns into a private, admission fee-charging museum). Free riders become a problem when non-excludable goods are also rivalrous.
For example, a government pavement is non-excludable as anyone may use it but rivalrous as, the more people using it, the more likely it will be too crowded for another to join. Public property is sometimes used interchangeably with public good, [17] usually impure public goods. They may also be a club good, which is excludable and non ...
