In economics, a good is said to be rivalrous or a rival if its consumption by one consumer prevents simultaneous consumption by other consumers, [1] or if consumption by one party reduces the ability of another party to consume it. A good is considered non-rivalrous or non-rival if, for any level of production, the cost of providing it to a marginal (additional) individual is zero. [2] A good is "anti-rivalrous" and "inclusive" if each person benefits more when other people consume it.

A good can be placed along a continuum from rivalrous through non-rivalrous to anti-rivalrous. The distinction between rivalrous and non-rivalrous is sometimes referred to as jointness of supply or subtractable or non-subtractable. [3] Economist Paul Samuelson made the distinction between private and public goods in 1954 by introducing the concept of nonrival consumption. Economist Richard Musgrave followed on and added rivalry and excludability as criteria for defining consumption goods in 1959 and 1969. [4]  

Rivalry

Most tangible goods, both durable and nondurable, are rival goods. A hammer is a durable rival good. One person's use of the hammer prevents others from using the hammer at the same time. However, the first user does not "use up" the hammer, meaning that some rival goods can still be shared through time. An apple is a nondurable rival good: once an apple is eaten, it is "used up" and can no longer be eaten by others. Non-tangible goods can also be rivalrous. Examples include the ownership of radio spectra and domain names. In more general terms, almost all private goods are rivalrous.

Non-rivalry

In contrast, non-rival goods may be consumed by one consumer without preventing simultaneous consumption by others. Most examples of non-rival goods are intangible. Broadcast television is an example of a non-rival good; when a consumer turns on a TV set, this does not prevent the TV in another consumer's house from working. The television itself is a rival good, but television broadcasts are non-rival goods. Other examples of non-rival goods include a beautiful scenic view, national defense, clean air, street lights, and public safety. More generally, most intellectual property is non-rival. In fact, certain types of intellectual property become more valuable as more people consume them (anti-rival). For example, the more people use a particular language, the more valuable that language becomes.

Non-rivalry does not imply that the total production costs are low, but that the marginal production costs are zero. In reality, few goods are completely non-rival as rivalry can emerge at certain levels. For instance, use of public roads, the Internet, or police/law courts is non-rival up to a certain capacity, after which congestion means that each additional user decreases speed for others. For that, recent economic theory views rivalry as a continuum, not as a binary category, [5] where many goods are somewhere between the two extremes of completely rival and completely non-rival. A perfectly non-rival good can be consumed simultaneously by an unlimited number of consumers.

Anti-rivalry

Goods are anti-rivalrous and inclusive if the consumer’s enjoyment increases with how many others consume the good. The concept was introduced by Steven Weber (2004), saying that when more people use free and open-source software, it becomes easier and more powerful for all users. [6] Lessig noted that any natural language is anti-rivalrous, because its utility increases with how much it's used by others. [7] Cooper noted that efforts to combat climate change are perversely anti-rivalrous, because the US will benefit from the efforts of others to combat this problem, even if it refuses to do so. [8]

In the social sciences, the free-rider problem is a type of market failure that occurs when those who benefit from resources, public goods and common pool resources do not pay for them or under-pay. Examples of such goods are public roads or public libraries or services or other goods of a communal nature. Free riders are a problem for common pool resources because they may overuse it by not paying for the good. Consequently, the common pool resource may be under-produced overused or degraded. Additionally, it has been shown that despite evidence that people tend to be cooperative by nature, the presence of free-riders causes cooperation to deteriorate, perpetuating the free-rider problem.

<span class="mw-page-title-main">Public good (economics)</span> Good that is non-excludable and non-rival

In economics, a public good is a good that is both non-excludable and non-rivalrous. For such goods, users cannot be barred from accessing or using them for failing to pay for them. Also, use by one person neither prevents access of other people nor does it reduce availability to others. Therefore, the good can be used simultaneously by more than one person. This is in contrast to a common good, such as wild fish stocks in the ocean, which is non-excludable but rivalrous to a certain degree. If too many fish were harvested, the stocks would deplete, limiting the access of fish for others. A public good must be valuable to more than one user, otherwise, the fact that it can be used simultaneously by more than one person would be economically irrelevant.

Information goods are commodities that provide value to consumers as a result of the information it contains and refers to any good or service that can be digitalized. Examples of information goods includes books, journals, computer software, music and videos. Information goods can be copied, shared, resold or rented. Information goods are durable and thus, will not be destroyed through consumption. As information goods have distinct characteristics as they are experience goods, have returns to scale and are non-rivalrous, the laws of supply and demand that depend on the scarcity of products do not frequently apply to information goods. As a result, the buying and selling of information goods differs from ordinary goods. Information goods are goods whose unit production costs are negligible compared to their amortized development costs. Well-informed companies have development costs that increase with product quality, but their unit cost is zero. Once an information commodity has been developed, other units can be produced and distributed at almost zero cost. For example, allow downloads over the Internet. Conversely, for industrial goods, the unit cost of production and distribution usually dominates. Firms with an industrial advantage do not incur any development costs, but unit costs increase as product quality improves.

The theory of consumer choice is the branch of microeconomics that relates preferences to consumption expenditures and to consumer demand curves. It analyzes how consumers maximize the desirability of their consumption, by maximizing utility subject to a consumer budget constraint. Factors influencing consumers' evaluation of the utility of goods include: income level, cultural factors, product information and physio-psychological factors.

<span class="mw-page-title-main">Normal good</span> Good that increases in demand when incomes rise

In economics, a normal good is a type of a good which experiences an increase in demand due to an increase in income, unlike inferior goods, for which the opposite is observed. When there is an increase in a person's income, for example due to a wage rise, a good for which the demand rises due to the wage increase, is referred as a normal good. Conversely, the demand for normal goods declines when the income decreases, for example due to a wage decrease or layoffs.

<span class="mw-page-title-main">Goods</span> Tangible or intangible things that satisfy human wants and can be transferred

In economics, goods are items that satisfy human wants and provide utility, for example, to a consumer making a purchase of a satisfying product. A common distinction is made between goods which are transferable, and services, which are not transferable.

<span class="mw-page-title-main">Private good</span>

A private good is defined in economics as "an item that yields positive benefits to people" 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; and rivalrous, i.e. consumption by one necessarily prevents that of another. A private good, as an economic resource is scarce, which can cause competition for it. The market demand curve for a private good is a horizontal summation of individual demand curves.

<span class="mw-page-title-main">Club good</span>

Club goods are a type of good in economics, 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 low rivalry in consumption. Thus, club goods have essentially zero marginal costs and are generally provided by what is commonly known as natural monopolies. Furthermore, club goods have artificial scarcity. Club theory is the area of economics that studies these goods. One of the most famous provisions was published by Buchanan in 1965 "An Economic Theory of Clubs," in which he addresses the question of how the size of the group influences the voluntary provision of a public good and more fundamentally provides a theoretical structure of communal or collective ownership-consumption arrangements.

<span class="mw-page-title-main">Goods and services</span> Products and actions made and done to meet the wants and needs of people

Goods are items that are usually tangible, such as pens, physical books, salt, apples, and hats. Services are activities provided by other people, who include architects, suppliers, contractors, technologists, teachers, doctors, lawn care workers, dentists, barbers, waiters, online servers, a digital book, a digital video game or a digital movie. Taken together, it is the production, distribution, and consumption of goods and services which underpins all economic activity and trade. According to economic theory, consumption of goods and services is assumed to provide utility (satisfaction) to the consumer or end-user, although businesses also consume goods and services in the course of producing other goods and services.

A use tax is a type of tax levied in the United States by numerous state governments. It is essentially the same as a sales tax but is applied not where a product or service was sold but where a merchant bought a product or service and then converted it for its own use, without having paid tax when it was initially purchased. Use taxes are functionally equivalent to sales taxes. They are typically levied upon the use, storage, enjoyment, or other consumption in the state of tangible personal property that has not been subjected to a sales tax.

In traditional usage, a global public good is a public good available on a more-or-less worldwide basis. There are many challenges to the traditional definition, which have far-reaching implications in the age of globalization.

<span class="mw-page-title-main">Final good</span> Commodity which is produced and subsequently consumed by the consumer

A final good or consumer good is a final product ready for sale that is used by the consumer to satisfy current wants or needs, unlike an intermediate good, which is used to produce other goods. A microwave oven or a bicycle is a final good, but the parts purchased to manufacture them are intermediate goods.

In economics, a common-pool resource (CPR) is a type of good consisting of a natural or human-made resource system, whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use. Unlike pure public goods, common pool resources face problems of congestion or overuse, because they are subtractable. A common-pool resource typically consists of a core resource, which defines the stock variable, while providing a limited quantity of extractable fringe units, which defines the flow variable. While the core resource is to be protected or nurtured in order to allow for its continuous exploitation, the fringe units can be harvested or consumed.

<span class="mw-page-title-main">Excludability</span>

In economics, a good, service or resource are broadly assigned two fundamental characteristics; a degree of excludability and a degree of rivalry. Excludability is defined as the degree to which a good, service or resource can be limited to only paying customers, or conversely, the degree to which a supplier, producer or other managing body can prevent "free" consumption of a good.

Anti-consumerism is a sociopolitical ideology that is opposed to consumerism, the continual buying and consuming of material possessions. Anti-consumerism is concerned with the private actions of business corporations in pursuit of financial and economic goals at the expense of the public welfare, especially in matters of environmental protection, social stratification, and ethics in the governing of a society. In politics, anti-consumerism overlaps with environmental activism, anti-globalization, and animal-rights activism; moreover, a conceptual variation of anti-consumerism is post-consumerism, living in a material way that transcends consumerism.

<span class="mw-page-title-main">Common good (economics)</span>

Common goods are defined in economics as goods that are rivalrous and non-excludable. Thus, they constitute one of the four main types based on the criteria:

Anti-rival good” is a neologism suggested by Steven Weber. According to his definition, it is the opposite of a rival good. The more people share an anti-rival good, the more utility each person receives. Examples include software and other information goods created through the process of commons-based peer production.

Property rights are constructs in economics for determining how a resource or economic good is used and owned, which have developed over ancient and modern history, from Abrahamic law to Article 17 of the Universal Declaration of Human Rights. Resources can be owned by individuals, associations, collectives, or governments.
