CurrencyIn economics, currency refers to a generally accepted medium of exchange. These are usually the coins and banknotes of a particular government, which comprise the physical aspects of a nation's money supply. The other part of a nation's money supply consists of bank deposits (sometimes called deposit money), ownership of which can be transferred by means of cheques, debit cards, or other forms of money transfer. Deposit money and currency are money in the sense that both are acceptable as a means of payment. Direct exchange of commodities such as precious metals, furs, grain, etc. in early human societies lead to the first money proper in early civilizations. Until modern times, precious metals such as gold or silver typically were used to retain the commodity nature of the store of value function of money. However, nearly all contemporary monetary systems are based on fiat money. Usually, a government declares its currency (including notes and coins issued by the central bank) to be legal tender, making it unlawful to not accept it as a means of repayment for all debts, public and private. In major modern economies such as those of the United States or the Euro Zone, most money is electronic, but the "currency" of these polities may, depending on context, include all money or just specie. IV Organization of IndustriesMonopolyA monopoly exists when a specific person or enterprise is the only supplier of a particular commodity (this contrasts with a monopsony which relates to a single entity's control of a market to purchase a good or service, and with oligopoly which consists of a few entities dominating an industry) Monopolies are thus characterized by a lack of economic competition to produce the good or service and a lack of viable substitute goods. The verb "monopolize" refers to the process by which a company gains the ability to raise prices or exclude competitors. In economics, a monopoly is a single seller. In law, a monopoly is business entity that has significant market power, that is, the power, to charge high prices. Although monopolies may be big businesses, size is not a characteristic of a monopoly. A small business may still have the power to raise prices in a small industry (or market). A monopoly is distinguished from a monopsony, in which there is only one buyer of a product or service; a monopoly may also have monopsony control of a sector of a market. Likewise, a monopoly should be distinguished from a cartel (a form of oligopoly), in which several providers act together to coordinate services, prices or sale of goods. Monopolies, monopsonies and oligopolies are all situations such that one or a few of the entities have market power and therefore interact with their customers (monopoly), suppliers (monopsony) and the other companies (oligopoly) in a game theoretic manner – meaning that expectations about their behaviour affects other players' choice of strategy and vice versa. This is to be contrasted with the model of perfect competition in which companies are "price takers" and do not have market power. When not coerced legally to do otherwise, monopolies typically maximize their profit by producing fewer goods and selling them at higher prices than would be the case for perfect competition. (See also Bertrand, Cournot or Stackelberg equilibria, market power, market share, market concentration, Monopoly profit, industrial economics). Sometimes governments decide legally that a given company is a monopoly that doesn't serve the best interests of the market and/or consumers. Governments may force such companies to divide into smaller independent corporations as was the case of United States v. AT&T, or alter its behaviour as was the case of United States v. Microsoft, to protect consumers. Monopolies can be established by a government, form naturally, or form by mergers. A monopoly is said to be coercive when the monopoly actively prohibits competitors by using practices (such as underselling) which derive from its market or political influence (see Chainstore paradox). There is often debate of whether market restrictions are in the best long-term interest of present and future consumers. In many jurisdictions, competition laws restrict monopolies. Holding a dominant position or a monopoly of a market is not illegal in it, however certain categories of behaviour can, when a business is dominant, be considered abusive and therefore incur legal sanctions. A government-granted monopoly or legal monopoly, by contrast, is sanctioned by the state, often to provide an incentive to invest in a risky venture or enrich a domestic interest group. Patents, copyright, and trademarks are sometimes used as examples of government granted monopolies, but they rarely provide market power. The government may also reserve the venture for itself, thus forming a government monopoly.
In general, the main results from this theory compare price-fixing methods across market structures, analyze the effect of a certain structure on welfare, and vary technological/demand assumptions in order to assess the consequences for an abstract model of society. Most economic textbooks follow the practice of carefully explaining the perfect competition model, only because of its usefulness to understand "departures" from it (the so-called imperfect competition models). The boundaries of what constitutes a market and what doesn't are relevant distinctions to make in economic analysis. In a general equilibrium context, a good is a specific concept entangling geographical and time-related characteristics. Most studies of market structure relax a little their definition of a good, allowing for more flexibility at the identification of substitute-goods. Therefore, one can find an economic analysis of the market of grapes in Russia, for example, which is not a market in the strict sense of general equilibrium theory monopoly.
