The coincidence of wants (often known as double coincidence of wants) [1] [2] [ verification needed ] is an economic phenomenon where two parties each hold an item that the other wants, so they exchange these items directly. Within economics, this has often been presented as the foundation of a bartering economy. [3]
In principle, double coincidence of wants would mean that both parties must agree to sell and buy each commodity. Under this system, problems arise through the improbability of the wants, needs, or events that cause or motivate a transaction occurring at the same time and the same place. One example is the bar musician who is "paid" with liquor or food, items which his landlord will not accept as rent payment, when the musician would rather have a month's shelter. If, instead, the musician's landlord were to throw a party and desire music for it, hiring the musician to play it by offering the month's rent in exchange, a coincidence of wants would exist.
In-kind transactions have several limitations as it only effectively works if one party actually has the item, or is willing to make said item, that the other party is seeking. Having a monetary medium can resolve this issue as it provides freedom for the former to work on or give away other items of interest, instead of being burdened to provide a particular item to the latter, impeding innovation in the long term, especially if barter was implemented on a larger scale. They can also only focus on satisfying parties that have monetary medium. Meanwhile, the latter party can use their medium of wage to wait and see which party would provide them the item they want.
Besides barter, other kinds of in-kind transactions also suffer from the coincidence of wants problem in the absence of a medium of exchange. Romance, for example often relies on a double coincidence of wants. If Max likes Mallory but Mallory does not like Max, then the two cannot meaningfully exchange the benefits of romance. Only if there exists a coincidence of wants can a mutually beneficial relationship be established without a medium of exchange.
John Hickman argues that barter may characterize future interplanetary trade because the much lower costs of communication compared with transportation will make a shared currency between the economies of the two worlds impossible. [4]
As another example, when wealth is transferred during marriage, divorce, inheritance, and other crucial life events, or during the collection of taxes or tribute, it is improbable that this event will coincide with the recipient's desire for the commodities the payer can readily obtain. All of these transactions entail an improbable coincidence of wants and events which can be resolved by the existence of a monetary medium.
In trade, barter (derived from bareter is a system of exchange in which participants in a transaction directly exchange goods or services for other goods or services without using a medium of exchange, such as money. Economists usually distinguish barter from gift economies in many ways; barter, for example, features immediate reciprocal exchange, not one delayed in time. Barter usually takes place on a bilateral basis, but may be multilateral. In most developed countries, barter usually exists parallel to monetary systems only to a very limited extent. Market actors use barter as a replacement for money as the method of exchange in times of monetary crisis, such as when currency becomes unstable or simply unavailable for conducting commerce.
A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.
Commodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects having value or use in themselves as well as their value in buying goods. This is in contrast to representative money, which has no intrinsic value but represents something of value such as gold or silver, for which it can be exchanged, and fiat money, which derives its value from having been established as money by government regulation.
A gift economy or gift culture is a system of exchange where valuables are not sold, but rather given without an explicit agreement for immediate or future rewards. Social norms and customs govern giving a gift in a gift culture; although there is some expectation of reciprocity, gifts are not given in an explicit exchange of goods or services for money, or some other good or service. This contrasts with a barter economy or a market economy, where goods and services are primarily explicitly exchanged for value received.
A store of value is any commodity or asset that would normally retain purchasing power into the future and is the function of the asset that can be saved, retrieved and exchanged at a later time, and be predictably useful when retrieved.
In economics, unit of account is one of the functions of money. A unit of account is a standard numerical monetary unit of measurement of the market value of goods, services, and other transactions. Also known as a "measure" or "standard" of relative worth and deferred payment, a unit of account is a necessary prerequisite for the formulation of commercial agreements that involve debt.
In economics, a medium of exchange is any item that is widely acceptable in exchange for goods and services. In modern economies, the most commonly used medium of exchange is currency. Most forms of money are categorised as mediums of exchange, including commodity money, representative money, cryptocurrency, and most commonly fiat money. Representative and fiat money most widely exist in digital form as well as physical tokens, for example coins and notes.
In classical economics, Say's law, or the law of markets, is the claim that the production of a product creates demand for another product by providing something of value which can be exchanged for that other product. So, production is the source of demand. In his principal work, A Treatise on Political Economy, Jean-Baptiste Say wrote: "A product is no sooner created, than it, from that instant, affords a market for other products to the full extent of its own value." And also, "As each of us can only purchase the productions of others with his/her own productions – as the value we can buy is equal to the value we can produce, the more men can produce, the more they will purchase."
Economic anthropology is a field that attempts to explain human economic behavior in its widest historic, geographic and cultural scope. It is an amalgamation of economics and anthropology. It is practiced by anthropologists and has a complex relationship with the discipline of economics, of which it is highly critical. Its origins as a sub-field of anthropology began with work by the Polish founder of anthropology Bronislaw Malinowski and the French Marcel Mauss on the nature of reciprocity as an alternative to market exchange. For the most part, studies in economic anthropology focus on exchange.
Quasi money can be defined as highly liquid assets which are not cash but can easily be converted into cash.
A complementary currency is a currency or medium of exchange that is not necessarily a national currency, but that is thought of as supplementing or complementing national currencies. Complementary currencies are usually not legal tender and their use is based on agreement between the parties exchanging the currency. According to Jérôme Blanc of Laboratoire d'Économie de la Firme et des Institutions, complementary currencies aim to protect, stimulate or orientate the economy. They may also be used to advance particular social, environmental, or political goals.
Countertrade means exchanging goods or services which are paid for, in whole or in part, with other goods or services, rather than with money. A monetary valuation can however be used in countertrade for accounting purposes. In dealings between sovereign states, the term bilateral trade is used.
The history of money is the development over time of systems for the exchange, storage, and measurement of wealth. Money is a means of fulfilling these functions indirectly and in general rather than directly, as with barter.
In economics, a market is a composition of systems, institutions, procedures, social relations or infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services to buyers in exchange for money. It can be said that a market is the process by which the value of goods and services are established. Markets facilitate trade and enable the distribution and allocation of resources in a society. Markets allow any tradeable item to be evaluated and priced. A market emerges more or less spontaneously or may be constructed deliberately by human interaction in order to enable the exchange of rights of services and goods. Markets generally supplant gift economies and are often held in place through rules and customs, such as a booth fee, competitive pricing, and source of goods for sale.
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.
Metallism is the economic principle that the value of money derives from the purchasing power of the commodity upon which it is based. The currency in a metallist monetary system may be made from the commodity itself or it may use tokens redeemable in that commodity. Georg Friedrich Knapp (1842–1926) coined the term "metallism" to describe monetary systems using coin minted in silver, gold or other metals.
Credit theories of money, also called debt theories of money, are monetary economic theories concerning the relationship between credit and money. Proponents of these theories, such as Alfred Mitchell-Innes, sometimes emphasize that money and credit/debt are the same thing, seen from different points of view. Proponents assert that the essential nature of money is credit (debt), at least in eras where money is not backed by a commodity such as gold. Two common strands of thought within these theories are the idea that money originated as a unit of account for debt, and the position that money creation involves the simultaneous creation of debt. Some proponents of credit theories of money argue that money is best understood as debt even in systems often understood as using commodity money. Others hold that money equates to credit only in a system based on fiat money, where they argue that all forms of money including cash can be considered as forms of credit money.
Randall D. Wright is a Canadian academic macroeconomist who advanced the fields of monetary economics and labor economics through his role in the development of matching theory.
The Philosophy of Money is a book on economic sociology by German sociologist and social philosopher Georg Simmel. Considered to be the theorist's greatest work, Simmel's book views money as a structuring agent that helps people understand the totality of life.
A moneyless economy or nonmonetary economy is a system for allocation of goods and services without payment of money. The simplest example is the family household. Other examples include barter economies, gift economies and primitive communism.
