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 ...

Turnstile Jumping In Moscow Metro (1)
A turnstile (also called a gateline, baffle gate, automated gate, turn gate in some regions) is a form of gate which allows one person to pass at a time. A turnstile can be configured to enforce One-way traffic#One-way traffic of people, one-way human traffic. In addition, a turnstile can restrict passage only to people who insert a coin, ticket, transit pass, security credential, or other method of payment or verification. Modern turnstiles can incorporate biometrics, including retina scanning, fingerprints, and other individual human characteristics which can be scanned. Thus a turnstile can be used in the case of Fare control, paid access (sometimes called a faregate or ticket barrier when used for this purpose), for example to access public transport, a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building. History Turnstiles were originally used, like other forms of stile, to allow human beings to pass while excluding live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opportunity Cost
In microeconomic theory, the opportunity cost of a choice is the value of the best alternative forgone where, given limited resources, a choice needs to be made between several mutually exclusive alternatives. Assuming the best choice is made, it is the "cost" incurred by not enjoying the ''benefit'' that would have been had if the second best available choice had been taken instead. The '' New Oxford American Dictionary'' defines it as "the loss of potential gain from other alternatives when one alternative is chosen". As a representation of the relationship between scarcity and choice, the objective of opportunity cost is to ensure efficient use of scarce resources. It incorporates all associated costs of a decision, both explicit and implicit. Thus, opportunity costs are not restricted to monetary or financial costs: the real cost of output forgone, lost time, pleasure, or any other benefit that provides utility should also be considered an opportunity cost.

Altruism
Altruism is the concern for the well-being of others, independently of personal benefit or reciprocity. The word ''altruism'' was popularised (and possibly coined) by the French philosopher Auguste Comte in French, as , for an antonym of egoism. He derived it from the Italian , which in turn was derived from Latin , meaning "alterity, other people" or "somebody else". Altruism may be considered a synonym of selflessness, the opposite of self-centeredness. Altruism is an important moral value in many cultures and religions. It can Moral circle expansion, expand beyond care for humans to include other Sentience, sentient beings and future generations. Altruism, as observed in populations of organisms, is when an individual performs an action at a cost to itself (in terms of e.g. pleasure and quality of life, time, probability of survival or reproduction) that benefits, directly or indirectly, another individual, without the expectation of reciprocity or compensation for that ac ...

Collective Action
Collective action refers to action taken together Advocacy group, by a group of people whose goal is to enhance their condition and achieve a common objective. It is a term that has formulations and theories in many areas of the social sciences including psychology, sociology, anthropology, political science and economics. The social identity model Researchers Martijn van Zomeren, Tom Postmes, and Russell Spears conducted a meta-analysis of over 180 studies of collective action, in an attempt to integrate three dominant socio-psychological perspectives explaining antecedent conditions to this phenomenon – injustice, efficacy, and identity. In their resultant 2008 review article, an integrative Social Identity Model of Collective Action (SIMCA) was proposed which accounts for interrelationships among the three predictors as well as their predictive capacities for collective action. An important assumption of this approach is that people tend to respond to subjective states of di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Capital
Human capital or human assets is a concept used by economists to designate personal attributes considered useful in the production process. It encompasses employee knowledge, skills, know-how, good health, and education. Human capital has a substantial impact on individual earnings. Research indicates that human capital investments have high economic returns throughout childhood and young adulthood. Companies can invest in human capital; for example, through education and training, improving levels of quality and production. History Adam Smith included in his definition of Capital (economics), capital "the acquired and useful abilities of all the inhabitants or members of the society". The first use of the term "human capital" may be by Irving Fisher. An early discussion with the phrase "human capital" was from Arthur Cecil Pigou: But the term only found widespread use in economics after its popularization by economists of the Chicago School of economics, Chicago School, in ...

Shifting Interest
In property law and real estate, a future interest is a legal right to property ownership that does not include the right to present possession or enjoyment of the property. Future interests are created on the formation of a defeasible estate; that is, an estate with a condition or event triggering transfer of possessory ownership. A common example is the landlord-tenant relationship. The landlord may own a house, but has no general right to enter it while it is being rented. The conditions triggering the transfer of possession, first to the tenant then back to the landlord, are usually detailed in a lease. As a slightly more complicated example, suppose O is the owner of Blackacre. Consider what happens when O transfers the property, "to A for life, then to B". Person A acquires possession of Blackacre. Person B does not receive any right to possess Blackacre immediately; however, once person A dies, possession will fall to person B (or his estate, if he died before person A ...

Capitalist Economics
In economics, a free market is an economic system in which the prices of goods and services are determined by supply and demand expressed by sellers and buyers. Such markets, as modeled, operate without the intervention of government or any other external authority. Proponents of the free market as a normative ideal contrast it with a regulated market, in which a government intervenes in supply and demand by means of various methods such as taxes or regulations. In an idealized free market economy, prices for goods and services are set solely by the bids and offers of the participants. Scholars contrast the concept of a free market with the concept of a coordinated market in fields of study such as political economy, new institutional economics, economic sociology, and political science. All of these fields emphasize the importance in currently existing market systems of rule-making institutions external to the simple forces of supply and demand which create space for those f ...

Pareto Optimal
In welfare economics, a Pareto improvement formalizes the idea of an outcome being "better in every possible way". A change is called a Pareto improvement if it leaves at least one person in society better off without leaving anyone else worse off than they were before. A situation is called Pareto efficient or Pareto optimal if all possible Pareto improvements have already been made; in other words, there are no longer any ways left to make one person better off without making some other person worse-off. In social choice theory, the same concept is sometimes called the unanimity principle, which says that if ''everyone'' in a society ( non-strictly) prefers A to B, society as a whole also non-strictly prefers A to B. The Pareto front consists of all Pareto-efficient situations. In addition to the context of efficiency in ''allocation'', the concept of Pareto efficiency also arises in the context of ''efficiency in production'' vs. ''x-inefficiency'': a set of outputs of goo ...

Effects Of Climate Change
Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an Instrumental temperature record, overall warming trend, Effects of climate change on the water cycle, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires, thawing permafrost, and desertification. These changes impact ecosystems and societies, and can become irreversible once Tipping points in the climate system, tipping points are crossed. Climate activists are engaged in a range of activities around the world that seek to ameliorate these issues or prevent them from happening. The effects of climate change vary in timing and location. Up until now the polar amplification, Arctic has warmed faster than most other regions due to climate change feedbacks. Surface air temperatures over land have also increased at ab ...
