Common good (economics)

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:

  • whether the consumption of a good by one person precludes its consumption by another person (rivalrousness)
  • whether it is possible to prevent people (consumers) who have not paid for it from having access to it (excludability)

One modern example is climate stability.[1] Classic examples of common goods are water and air. Water and air can be polluted: water flows can be tapped beyond sustainability, and air is often used in combustion, whether by motor vehicles, smokers, factories, wood fires. In the production process these resources and others are changed into finished products such as food, shoes, toys, furniture, cars, houses and televisions. Another example of a private exploitation treated as a renewable resource and commonly cited have been trees or timber at critical stages, oil, mined metals, and crops. Fish stocks in international waters are also cited often. In this latter example, when fish are withdrawn from the water without any limits being imposed, living stocks of fish are likely to be depleted for any later fishermen. To describe situations in which economic users withdraw resources to secure short-term gains without regard for the long-term consequences, the term tragedy of the commons was coined. For example, forest exploitation leads to barren lands, and overfishing leads to a reduction of overall fish stocks, both of which eventually result in diminishing yields to be withdrawn periodically.

Debates about sustainability can be both philosophical and scientific.[2][3][4] However, wise-use advocates consider common goods that are an exploitable form of a renewable resource, such as fish stocks, grazing land, etc., to be sustainable in the following two cases:

  • As long as demand for the goods withdrawn from the common good does not exceed a certain level, future yields are not diminished and the common good as such is being preserved as a 'sustainable' level.
  • If access to the common good is regulated at the community level by restricting exploitation to community members and by imposing limits to the quantity of goods being withdrawn from the common good, the tragedy of the commons may be avoided. Common goods that are sustained through an institutional arrangement of this kind are referred to as common-pool resources.

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.

Air rights

Air rights are the property interest in the "space" above the earth's surface. Generally speaking, owning, or renting, land or a building includes the right to use and develop the space above the land without interference by others.

This legal concept is encoded in the Latin phrase Cuius est solum, eius est usque ad coelum et ad inferos ("Whoever owns the soil, it is theirs up to Heaven and down to Hell."), which appears in medieval Roman law and is credited to 13th-century glossator Accursius; it was notably popularized in common law in Commentaries on the Laws of England (1766) by William Blackstone; see origins of phrase for details.

CC–PP game

The Commonize Costs–Privatize Profits Game (or CC–PP Game) is a concept developed by the ecologist Garrett Hardin to describe a "game" (in the game theory sense) widely played in matters of resource allocation. The concept is Hardin’s interpretation of the closely related phenomenon known as the tragedy of the commons, and is referred to in political discourse as "privatizing profits and socializing losses."

The CC–PP Game originally appeared in Hardin’s book titled Filters against Folly: How To Survive Despite Economists, Ecologists, and the Merely Eloquent which was published in 1986.Players of the CC–PP Game aim to commonize the costs (or externalities) generated by their activities across the wider community, while privatizing all profits (financial or otherwise) to themselves. The individual does not broadcast that they are playing the game in order to continue profiting.Hardin related the CC–PP Game to ecological problems such mining, groundwater overdraft, cattle ranching and other actions that cause the depletion of natural resources or an increase in pollution.

Customary land

Customary land is land which is owned by indigenous communities and administered in accordance with their customs, as opposed to statutory tenure usually introduced during the colonial periods. Common ownership is one form of customary land ownership.

Since the late 20th century, statutory recognition and protection of indigenous and community land rights continues to be a major challenge. The gap between formally recognized and customarily held and managed land is a significant source of underdevelopment, conflict, and environmental degradation.In the Malawi Land Act of 1965, "Customary Land" is defined as "all land which is held, occupied or used under customary law, but does not include any public land". In most countries of the Pacific islands, customary land remains the dominant land tenure form. Distinct customary systems of tenure have evolved on different islands and areas within the Pacific region. In any country there may be many different types of customary tenure.The amount of customary land ownership out of the total land area of Pacific island nations is the following: 97% in Papua New Guinea, 90% in Vanuatu, 88% in Fiji, 87% in the Solomon Islands, and 81% in Samoa.

Free-rider problem

In the social sciences, the free-rider problem occurs when those who benefit from resources, public goods, or services do not pay for them, which results in an underprovision of those goods or services. For example, a free-rider may frequently ask for available parking lots (public goods) from those who have already paid for them, in order to benefit from free parking. That is, the free-rider may use the parking even more than the others without paying a penny. The free-rider problem is the question of how to limit free riding and its negative effects in these situations. The free-rider problem may occur when property rights are not clearly defined and imposed.The free-rider problem is common with goods which are non-excludable, including public goods and situations of the Tragedy of the Commons.

Although the term "free rider" was first used in economic theory of public goods, similar concepts have been applied to other contexts, including collective bargaining, antitrust law, psychology and political science. For example, some individuals in a team or community may reduce their contributions or performance if they believe that one or more other members of the group may free ride.

Intangible property

Intangible property, also known as incorporeal property, describes something which a person or corporation can have ownership of and can transfer ownership to another person or corporation, but has no physical substance, for example brand identity or knowledge/intellectual property. It generally refers to statutory creations such as copyright, trademarks, or patents. It excludes tangible property like real property (land, buildings, and fixtures) and personal property (ships, automobiles, tools, etc.). In some jurisdictions intangible property are referred to as choses in action. Intangible property is used in distinction to tangible property. It is useful to note that there are two forms of intangible property: legal intangible property (which is discussed here) and competitive intangible property (which is the source from which legal intangible property is created but cannot be owned, extinguished, or transferred). Competitive intangible property disobeys the intellectual property test of voluntary extinguishment and therefore results in the sources that create intellectual property (knowledge in its source form, collaboration, process-engagement, etc.) escaping quantification.

Generally, ownership of intangible property gives the owner a set of legally enforceable rights over reproduction of personal property containing certain content. For example, a copyright owner can control the reproduction of the work forming the copyright. However, the intangible property forms a set of rights separate from the tangible property that carries the rights. For example, the owner of a copyright can control the printing of books containing the content, but the book itself is personal property which can be bought and sold without concern over the rights of the copyright holder.

In English law and other Commonwealth legal systems, intangible property is traditionally divided in pure intangibles (such as debts, intellectual property rights and goodwill) and documentary intangibles, which obtain their character through the medium of a document (such as a bill of lading, promissory note or bill of exchange). The recent rise of electronic documents has blurred the distinction between pure intangibles and documentary intangibles.

International Association for the Study of the Commons

The International Association for the Study of the Commons (IASC) was founded in 1989 as The International Association for the Study of Common Property (IASCP). It is a non-for-profit organization that sees as its mission to further the understanding of institutions for the management of resources that are or could be held or used collectively as a commons by communities in developing and industrialized countries.

According to its vision statement, the goals of the association are:

to encourage exchange of knowledge on the commons among diverse disciplines, areas, and resource types

to foster mutual exchange of scholarship and practical experience

to promote appropriate institutional design

Pierre-Joseph Proudhon

Pierre-Joseph Proudhon (; French: [pjɛʁʒozɛf pʁudɔ̃]; 15 January 1809 – 19 January 1865) was a French politician and the founder of mutualist philosophy. He was the first person to declare himself an anarchist, using that term and is widely regarded as one of the ideology's most influential theorists. Proudhon is even considered by many to be the "father of anarchism". He became a member of the French Parliament after the Revolution of 1848, whereafter he referred to himself as a federalist.Proudhon, who was born in Besançon, was a printer who taught himself Latin in order to better print books in the language. His best-known assertion is that "property is theft!", contained in his first major work, What is Property? Or, an Inquiry into the Principle of Right and Government (Qu'est-ce que la propriété? Recherche sur le principe du droit et du gouvernement), published in 1840. The book's publication attracted the attention of the French authorities. It also attracted the scrutiny of Karl Marx, who started a correspondence with its author. The two influenced each other and they met in Paris while Marx was exiled there. Their friendship finally ended when Marx responded to Proudhon's The System of Economic Contradictions, or The Philosophy of Poverty with the provocatively titled The Poverty of Philosophy. The dispute became one of the sources of the split between the anarchist and Marxist wings of the International Working Men's Association. Some such as Edmund Wilson have contended that Marx's attack on Proudhon had its origin in the latter's defense of Karl Grün, whom Marx bitterly disliked, but who had been preparing translations of Proudhon's work.

Proudhon favored workers' associations or co-operatives as well as individual worker/peasant possession over private ownership or the nationalization of land and workplaces. He considered social revolution to be achievable in a peaceful manner. In The Confessions of a Revolutionary, Proudhon asserted that "Anarchy is Order Without Power", the phrase which much later inspired in the view of some the anarchist circled-A symbol, today "one of the most common graffiti on the urban landscape". He unsuccessfully tried to create a national bank, to be funded by what became an abortive attempt at an income tax on capitalists and shareholders. Similar in some respects to a credit union, it would have given interest-free loans.


Property, in the abstract, is what belongs to or with something, whether as an attribute or as a component of said thing. In the context of this article, it is one or more components (rather than attributes), whether physical or incorporeal, of a person's estate; or so belonging to, as in being owned by, a person or jointly a group of people or a legal entity like a corporation or even a society. Depending on the nature of the property, an owner of property has the right to consume, alter, share, redefine, rent, mortgage, pawn, sell, exchange, transfer, give away or destroy it, or to exclude others from doing these things, as well as to perhaps abandon it; whereas regardless of the nature of the property, the owner thereof has the right to properly use it (as a durable, mean or factor, or whatever), or at the very least exclusively keep it.

In economics and political economy, there are three broad forms of property: private property, public property, and collective property (also called cooperative property).Property that jointly belongs to more than one party may be possessed or controlled thereby in very similar or very distinct ways, whether simply or complexly, whether equally or unequally. However, there is an expectation that each party's will (rather discretion) with regard to the property be clearly defined and unconditional, so as to distinguish ownership and easement from rent. The parties might expect their wills to be unanimous, or alternately every given one of them, when no opportunity for or possibility of dispute with any other of them exists, may expect his, her, its or their own will to be sufficient and absolute.

The Restatement (First) of Property defines property as anything, tangible or intangible whereby a legal relationship between persons and the state enforces a possessory interest or legal title in that thing. This mediating relationship between individual, property and state is called a property regime.In sociology and anthropology, property is often defined as a relationship between two or more individuals and an object, in which at least one of these individuals holds a bundle of rights over the object. The distinction between "collective property" and "private property" is regarded as a confusion since different individuals often hold differing rights over a single object.Important widely recognized types of property include real property (the combination of land and any improvements to or on the land), personal property (physical possessions belonging to a person), private property (property owned by legal persons, business entities or individual natural persons), public property (state owned or publicly owned and available possessions) and intellectual property (exclusive rights over artistic creations, inventions, etc.), although the last is not always as widely recognized or enforced. An article of property may have physical and incorporeal parts. A title, or a right of ownership, establishes the relation between the property and other persons, assuring the owner the right to dispose of the property as the owner sees fit.

Property rights (economics)

Property rights are theoretical socially-enforced constructs in economics for determining how a resource or economic good is used and owned. Resources can be owned by (and hence be the property of) individuals, associations or governments. Property rights can be viewed as an attribute of an economic good. This attribute has four broad components and is often referred to as a bundle of rights:

the right to use the good

the right to earn income from the good

the right to transfer the good to others

the right to enforce property rightsIn economics, property is usually considered to be ownership (rights to the proceeds generated by the property) and control over a resource or good. Many economists effectively argue that property rights need to be fixed and need to portray the relationships among other parties in order to be more effective.

Road space rationing

Road space rationing, also known as alternate-day travel, driving restriction, no-drive days, (Spanish: restricción vehicular; Portuguese: rodízio veicular; French: circulation alternée) is a travel demand management strategy aimed to reduce the negative externalities generated by urban air pollution or peak urban travel demand in excess of available supply or road capacity, through artificially restricting demand (vehicle travel) by rationing the scarce common good road capacity, especially during the peak periods or during peak pollution events. This objective is achieved by restricting traffic access into an urban cordon area, city center (CBD), or district based upon the last digits of the license number on pre-established days and during certain periods, usually, the peak hours.

The practical implementation of this traffic restraint policy is common in Latin America, and in many cases, the road rationing has as a main goal the reduction of air pollution, such as the cases of México City, and Santiago, Chile. São Paulo, with a fleet of 6 million vehicles in 2007, is the largest metropolis in the world with such a travel restriction, implemented first in 1996 as measured to mitigate air pollution, and thereafter made permanent in 1997 to relieve traffic congestion. More recent implementations in Costa Rica and Honduras have had the objective of reducing oil consumption, due to the high impact this import has on the economy of small countries, and considering the steep increases in oil prices that began in 2003. Bogotá, Quito, and La Paz, Bolivia also have similar driving restriction schemes in place.

After a temporary implementation of road space rationing to reduce air pollution in Beijing during the 2008 Summer Olympics, local officials put in place several permanent rationing schemes to improve the city's air quality. As of June 2016, another 11 Chinese cities have similar restriction schemes in place. Also, temporary driving restrictions to reduce cars on the streets by half during severe pollution events have been implemented in Paris and surrounding suburbs in March 2014, March 2015, and December 2016; in Beijing twice in December 2015, and one more time in December 2016; and also in Rome and Milan for several days in December 2015. A similar alternate-day travel temporary scheme was implemented in New Delhi as a two-week trial in January 2016. A temporary ban on diesel cars was implemented in Oslo on municipal roads in January 2017.

Tangible property

Tangible property in law is, literally, anything which can be touched, and includes both real property and personal property (or moveable property), and stands in distinction to intangible property.In English law and some Commonwealth legal systems, items of tangible property are referred to as choses in possession (or a chose in possession in the singular). However, some property, despite being physical in nature, is classified in many legal systems as intangible property rather than tangible property because the rights associated with the physical item are of far greater significance than the physical properties. Principally, these are documentary intangibles. For example, a promissory note is a piece of paper that can be touched, but the real significance is not the physical paper, but the legal rights which the paper confers, and hence the promissory note is defined by the legal debt rather than the physical attributes.A unique category of property is money, which in some legal systems is treated as tangible property and in others as intangible property. Whilst most countries legal tender is expressed in the form of intangible property ("The Treasury of Country X hereby promises to pay to the bearer on demand...."), in practice banknotes are now rarely ever redeemed in any country, which has led to banknotes and coins being classified as tangible property in most modern legal systems.
