Non-excludable
In economics, excludability is 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 (e.g. a government) can prevent consumption of a good. In economics, a good, service or resource is broadly assigned two fundamental characteristics; a degree of excludability and a degree of rivalry. Excludability was originally proposed in 1954 by American economist Paul Samuelson where he formalised the concept now known as public goods, i.e. goods that are both non-rivalrous and non-excludable. Samuelson additionally highlighted the market failure of the free-rider problem that can occur with non-excludable goods. Samuelson's theory of good classification was then further expanded upon by Richard Musgrave in 1959, Garrett Hardin in 1968 who expanded upon another key market inefficiency of non-excludeable goods; the tragedy of the commons. Excludability is not an inherent char ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Good (economics)
In economics, a public good (also referred to as a social good or collective good)Oakland, W. H. (1987). Theory of public goods. In Handbook of public economics (Vol. 2, pp. 485–535). Elsevier. is a commodity, product or service that is both non-excludable and non-rivalrous and which is typically provided by a government and paid for through taxation. Use by one person neither prevents access by other people, nor does it reduce availability to others, so 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, its simultaneous availability to more than one person would be economically irrelevant. Capital goods may be used to produce public goods or services that are "...ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Rider Problem
In economics, 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. Free riders may overuse common pool resources by not paying for them, neither directly through fees or tolls, nor indirectly through taxes. Consequently, the common pool resource may be under-produced, overused, or degraded. Additionally, despite evidence that people tend to be cooperative by nature (a prosocial behaviour), the presence of free-riders has been shown to cause cooperation to deteriorate, perpetuating the free-rider problem. In social science, the free-rider problem is the question of how to limit free riding and its negative effects in these situations, such as the free-rider problem of when property rights are not clearly defined and imposed. The free-rider problem is common with public goods which are non-excludable and non-rivalrous. The non-excludability and non-rivalry o ...

Market Failure
In neoclassical economics, market failure is a situation in which the allocation of goods and services by a free market is not Pareto efficient, often leading to a net loss of economic value.Paul Krugman and Robin Wells Krugman, Robin Wells (2006). ''Economics'', New York, Worth Publishers. The first known use of the term by economists was in 1958,Francis M. Bator (1958). "The Anatomy of Market Failure," ''Quarterly Journal of Economics'', 72(3) pp351–379(press +). but the concept has been traced back to the Victorian writers John Stuart Mill and Henry Sidgwick.Steven G. Medema (2007). "The Hesitant Hand: Mill, Sidgwick, and the Evolution of the Theory of Market Failure," ''History of Political Economy'', 39(3)pp. 331��358. 200Online Working Paper. Market failures are often associated with public goods, time-inconsistent preferences, Information asymmetry, information asymmetries, Market structure, failures of competition, principal–agent problems, externalities,Jean-Jacques L ...

Goods
In economics, goods are anything that is good, usually in the sense that it provides welfare or utility to someone. Alan V. Deardorff, 2006. ''Terms Of Trade: Glossary of International Economics'', World Scientific. Online version: Deardorffs' Glossary of International Economics"good" an Goods can be contrasted with bads, i.e. things that provide negative value for users, like chores or waste. A bad lowers a consumer's overall welfare. Economics focuses on the study of economic goods, i.e. goods that are scarce; in other words, producing the good requires expending effort or resources. Economic goods contrast with free goods such as air, for which there is an unlimited supply.Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. Goods are the result of the Secondary sector of the economy which involves the transformation of raw materials or intermediate goods into goods.

Copyright Infringement
Copyright infringement (at times referred to as piracy) is the use of Copyright#Scope, works protected by copyright without permission for a usage where such permission is required, thereby infringing certain exclusive rights granted to the copyright holder, such as the right to reproduce, distribute, display or perform the protected work, or to produce derivative works. The copyright holder is usually the work's creator, or a publisher or other business to whom copyright has been assigned. Copyright holders routinely invoke legal and technological measures to prevent and penalize copyright infringement. Copyright infringement disputes are usually resolved through direct negotiation, a notice and take down process, or litigation in Civil law (common law), civil court. Egregious or large-scale commercial infringement, especially when it involves counterfeiting, or the fraudulent imitation of a product or brand, is sometimes prosecuted via the criminal justice system.

World Bank
The World Bank is an international financial institution that provides loans and Grant (money), grants to the governments of Least developed countries, low- and Developing country, middle-income countries for the purposes of economic development. The World Bank is the collective name for the International Bank for Reconstruction and Development (IBRD) and International Development Association (IDA), two of five international organizations owned by the World Bank Group. It was established along with the International Monetary Fund at the 1944 Bretton Woods Conference. After a slow start, its first loan was to France in 1947. In its early years, it primarily focused on rebuilding Europe. Over time, it focused on providing loans to developing world countries. In the 1970s, the World Bank re-conceptualized its mission of facilitating development as being oriented around poverty reduction. For the last 30 years, it has included NGOs and environmental groups in its loan portfolio. Its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tragedy Of The Commons
The tragedy of the commons is the concept that, if many people enjoy unfettered access to a finite, valuable resource, such as a pasture, they will tend to overuse it and may end up destroying its value altogether. Even if some users exercised voluntary restraint, the other users would merely replace them, the predictable result being a "tragedy" for all. The concept has been widely discussed, and criticised, in economics, ecology and other sciences. The metaphorical term is the title of a 1968 essay by ecologist Garrett Hardin. The concept itself did not originate with Hardin but rather extends back to classical antiquity, being discussed by Aristotle. The principal concern of Hardin's essay was overpopulation of the planet. To prevent the inevitable tragedy (he argued) it was necessary to reject the principle (supposedly enshrined in the Universal Declaration of Human Rights) according to which every family has a right to choose the number of its offspring, and to replace it b ...

Incomplete Contracts
In contract law, an incomplete contract is one that is defective or uncertain in a material respect. In economic theory, an incomplete contract (as opposed to a complete contract) is one that provides for the rights, obligations and remedies of the parties in every possible state of the world. Since the human mind is a scarce resource and the mind cannot collect, process, and understand an infinite amount of information, economic actors are limited in their rationality (the limitations of the human mind in understanding and solving complex problems) and one cannot anticipate all possible contingencies. Or perhaps because it is too expensive to write a complete contract, the parties will opt for a "sufficiently complete" contract. In short, in practice, every contract is incomplete for a variety of reasons and limitations. The incompleteness of a contract also means that the protection it provides may be inadequate. Even if a contract is incomplete, the legal validity of the contra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Information
Privacy (, ) is the ability of an individual or group to seclude themselves or information about themselves, and thereby express themselves selectively. The domain of privacy partially overlaps with security, which can include the concepts of appropriate use and Information security, protection of information. Privacy may also take the form of bodily integrity. Throughout history, there have been various conceptions of privacy. Most cultures acknowledge the right of individuals to keep aspects of their personal lives out of the public domain. The right to be free from unauthorized invasions of privacy by governments, corporations, or individuals is enshrined in the privacy laws of many countries and, in some instances, their constitutions. With the rise of technology, the debate regarding privacy has expanded from a bodily sense to include a digital sense. In most countries, the right to digital privacy is considered an extension of the original right to privacy, and many count ...
