Barter usually takes place on a [[bilateral trade|bilateral]] basis, but may be [[multilateral exchange|multilateral]] (if it is mediated through a [[trade exchange]]). 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 (such as [[hyperinflation]] or a [[Deflation#Deflationary spiral|deflationary spiral]]) or simply unavailable for conducting [[commerce]]. No [[ethnographic]] studies have shown that any present or past society has used barter without any other medium of exchange or measurement, and anthropologists have found no evidence that money emerged from barter. Nevertheless, economists since the times of [[Adam Smith]] (1723–1790) often imagined [[pre-modern societies]] as examples to use the [[inefficiency]] of barter to explain the emergence of money, of "the" [[economy]], and hence of the discipline of [[economics]] itself.<ref name="Graeber-p21-41">{{cite book|author= [[David Graeber]]|title= Debt: the first 5,000 years|url= https://archive.org/details/debtfirst5000yea00grae|url-access= registration|year= 2011|publisher= Melville House|location= New York|pages= [https://archive.org/details/debtfirst5000yea00grae/page/21 21–41]|isbn= 9781933633862}}</ref><ref>Modern barter is practised by barter exchanges that have hundreds or thousands of businesses as members who agree to barter their products and services on a third-party basis.

He argued that money was not the creation of governments. Markets emerged, in his view, out of the division of labour, by which individuals began to specialize in specific crafts and hence had to depend on others for subsistence goods. These goods were first exchanged by barter. Specialization depended on trade but was hindered by the "[[double coincidence of wants]]" which barter requires, i.e., for the exchange to occur, each participant must want what the other has. To complete this hypothetical history, craftsmen would stockpile one particular good, be it salt or metal, that they thought no one would refuse. This is the origin of money according to Smith. Money, as a universally desired medium of exchange, allows each half of the transaction to be separated.<ref name="Graeber-p21-41"/> Barter is characterized in Adam Smith's "''[[The Wealth of Nations]]''" by a disparaging vocabulary: "haggling, swapping, dickering". It has also been characterized as negative reciprocity, or "selfish profiteering".<ref>{{cite book|title=Barter, Exchange and Value: An Anthropological Approach|year=1992|url=https://archive.org/details/barterexchangeva00hump|url-access=limited|publisher=Cambridge University Press|location=Cambridge|page=[https://archive.org/details/barterexchangeva00hump/page/n6 3]|editor=Humphrey, Carolyn and Stephen Hugh-Jones}}</ref> ===David Graeber's theory=== Anthropologists such as David Graeber have argued, in contrast, "that when something resembling barter ''does'' occur in stateless societies it is almost always between strangers."<ref>{{cite book|last=Graeber|first=David|title=Toward an Anthropological Theory of Value: The False Coin of our Dreams|url=https://libcom.org/article/toward-anthropological-theory-value-false-coin-our-own-dreams-david-graeber|url-access=limited|year=2001|publisher=Palgrave|location=New York|page=[https://archive.org/details/towardanthropolo00grae_424/page/n168 154]}}</ref> Barter occurred between strangers, not fellow villagers, and hence cannot be used to naturalistically explain the origin of money without the state.

'''The parties of the barter transaction are both equal and free.''' :Neither party has advantages over the other, and both are free to leave the trade at any point in time. '''The transaction happens simultaneously.''' :The goods are normally traded at the same point in time. Nonetheless delayed barter in goods may rarely occur as well.<ref>{{Cite journal |last=Humphrey |first=Caroline |title=Barter and Economic Disintegration |journal = Man |year=1995 |volume=20 |issue=1 |pages=48–72 |language=English| doi=10.2307/2802221|jstor=2802221 }}</ref> In the case of services being traded however, the two parts of the trade may be separated. '''The transaction is transformative.''' :A barter transaction "moves objects between the regimes of value", meaning that a good or service that is being traded may take up a new meaning or value under its recipient than that of its original owner.<ref name=":0">{{Cite book |last=Humphrey |first=Caroline |title=Barter, Exchange and Value: An Anthropological Approach |publisher=Cambridge University Press |year=1992 |isbn=9781316582459 |pages=1–10 |language=English}}</ref> '''There is no criterion of value.''' :There is no real way to value each side of the trade. There is bargaining taking place, not to do with the value of each party's good or service, but because each player in the transaction wants what is offered by the other.<ref name=":0" /> ===Advantages=== Since direct barter does not require payment in money, it can be utilized when money is in short supply, when there is little information about the credit worthiness of trade partners, or when there is a lack of trust between those trading. Barter is an option to those who cannot afford to store their small supply of wealth in money, especially in [[hyperinflation]] situations where money devalues quickly.<ref>{{cite journal|last=Humphrey|first=Caroline|title=Barter and Economic Disintegration|journal=Man|year=1985|volume=20|issue=1|pages=66–7|doi=10.2307/2802221|jstor=2802221}}</ref> ===Limitations=== The limitations of barter are often explained in terms of its inefficiencies in facilitating exchange in comparison to money. It is said that barter is 'inefficient' because: ;There needs to be a 'double coincidence of wants' : For barter to occur between two parties, both parties need to have what the other wants. ;There is no common measure of value/ No Standard Unit of Account : In a monetary economy, money plays the role of a measure of the value of all goods, so their values can be assessed against each other; this role may be absent in a barter economy. ;Indivisibility of certain goods : If a person wants to buy a certain amount of another's goods, but only has for payment one indivisible unit of another good which is worth more than what the person wants to obtain, a barter transaction cannot occur. ;Lack of standards for deferred payments : This is related to the absence of a common measure of value, although if the debt is denominated in units of the good that will eventually be used in payment, it is not a problem. ;Difficulty in storing wealth : If a society relies exclusively on perishable goods, storing wealth for the future may be impractical. However, some barter economies rely on durable goods like sheep or cattle for this purpose.<ref>Robert E. Wright and Vincenzo Quadrini.

[[Olaus Magnus]], 1555]] Other anthropologists have questioned whether barter is typically between "total" strangers, a form of barter known as "silent trade". Silent trade, also called silent barter, dumb barter ("dumb" here used in its old meaning of "mute"), or depot trade, is a method by which [[Merchant|traders]] who cannot speak each other's [[language]] can trade without talking. However, Benjamin Orlove has shown that while barter occurs through "silent trade" (between strangers), it occurs in commercial markets as well. "Because barter is a difficult way of conducting trade, it will occur only where there are strong institutional constraints on the use of money or where the barter symbolically denotes a special social relationship and is used in well-defined conditions. To sum up, multipurpose money in markets is like lubrication for machines - necessary for the most efficient function, but not necessary for the existence of the market itself."<ref>{{cite book|title=Economic Anthropology|year=1989|publisher=Stanford University Press|location=Stanford, CA|pages=179|author=Plattner, Stuart|author-link=Markets and Marketplaces|editor=Plattner, Stuart}}</ref> In his analysis of barter between coastal and inland villages in the [[Trobriand Islands]], Keith Hart highlighted the difference between highly ceremonial gift exchange between community leaders, and the barter that occurs between individual households. The haggling that takes place between strangers is possible because of the larger temporary political order established by the gift exchanges of leaders. From this, he concludes that barter is "an atomized interaction predicated upon the presence of society" (i.e. that social order established by gift exchange), and not typical between strangers.<ref>{{cite book|last=M.

During such a crisis, currency may be in short supply, or highly devalued through hyperinflation. In such cases, money ceases to be the universal medium of exchange or standard of value. Money may be in such short supply that it becomes an item of barter itself rather than the means of exchange. Barter may also occur when people cannot afford to keep money (as when hyperinflation quickly devalues it).<ref>{{cite journal|last=Humphrey|first=Caroline|title=Barter and Economic Disintegration|journal=Man|year=1985|volume=20|issue=1|page=52|doi=10.2307/2802221|jstor=2802221}}</ref> An example of this would be during the [[Crisis in Bolivarian Venezuela]], when Venezuelans resorted to bartering as a result of hyperinflation.

All of these strategies are found in ancient economies including Ptolemaic Egypt. They are also the basis for more recent barter exchange systems.<ref>{{cite book|title=Trade and Market in the Early Empires |year=1957 |publisher=The Free Press |location=Glencoe, Illinois |page=14 |author=Polanyi, Karl |author-link=Karl Polanyi |editor=Polanyi, Karl|display-editors=etal}}</ref> While one-to-one bartering is practised between individuals and businesses on an informal basis, organized barter exchanges have developed to conduct third party bartering which helps overcome some of the limitations of barter. A barter exchange operates as a [[broker]] and bank in which each participating member has an account that is debited when purchases are made, and credited when sales are made. Modern barter and trade has evolved considerably to become an effective method of increasing sales, conserving cash, moving inventory, and making use of excess [[Productive capacity|production capacity]] for businesses around the world. Businesses in a barter earn trade credits (instead of cash) that are deposited into their account. They then have the ability to purchase goods and services from other members utilizing their trade credits – they are not obligated to purchase from those whom they sold to, and vice versa. The exchange plays an important role because they provide the record-keeping, brokering expertise and monthly statements to each member. Commercial exchanges make money by charging a commission on each transaction either all on the buy side, all on the sell side, or a combination of both. Transaction fees typically run between 8 and 15%. A successful example is [[International Monetary Systems (IMS Barter)|International Monetary Systems]], which was founded in 1985 and is one of the first exchanges in North America opened after the TEFRA Act of 1982. === Organized barter (retail barter) === Since the 1930s, organized barter has been a common type of barter where company's join a barter organization (barter company) which serves as a hub to exchange goods and services without money as a medium of exchange. Similarly to brokerage houses, barter company facilitates the exchange of goods and services between member companies, allowing members to acquire goods and services by providing their own as payment. Member companies are required to sign a barter agreement with the barter company as a condition of their membership. In turn, the barter company provides each member with the current levels of supply and demand for each good and service which can be purchased or sold in the system. These transactions are mediated by barter authorities of the member companies. The barter member companies can then acquire their desired goods or services from another member company within a predetermined time. Failure to deliver the good or service within the fixed time period results in the debt being settled in cash. Each member company pays an annual membership fee and purchase and sales commission outlined in the contract. Organized barter increases liquidity for member companies as it mitigates the requirement of cash to settle transactions, enabling sales and purchases to be made with excess capacity or surplus inventory. Additionally, organized barter facilitates competitive advantage within industries and sectors. Considering the quantity of transactions depending on the supply-demand balance of the goods and services within the barter organization, member companies tend to face minimal competition within their own operating sector.{{citation needed|date=May 2023}} === Corporate barter === Producers, wholesalers and distributors tend to engage in corporate barter as a method of exchanging goods and services with companies they are in business with.<ref name=":1">{{Cite journal |last=Uyan |first=Ozgul |date=2017 |title=Barter as an alternative trading and financing tool and its importance for businesses in times of economic crisis |url=https://www.pressacademia.org/archives/jefa/v4/i3/8.pdf |journal=Journal of Economics, Finance and Accounting |volume=4 |issue=3 |pages=289}}</ref> These bilateral barter transactions are targeted towards companies aiming to convert stagnant inventories into receivable goods or services, to increase market share without cash investments, and to protect liquidity. However, issues arise as to the imbalance of supply and demand of desired goods and services and the inability to efficiently match the value of goods and services exchanged in these transactions.<ref name=":1" /> ====Labour notes==== {{main article|Utopian socialism|Time banking}} [[File:LaborNote.JPG|thumb|right|350px|A 19th-century example of barter: A sample labour for labour note for the [[Cincinnati Time Store]]. Scanned from ''Equitable Commerce'' by [[Josiah Warren]] (1846)]] The Owenite socialists in Britain and the United States in the 1830s were the first to attempt to organize barter exchanges. Owenism developed a "theory of equitable exchange" as a critique of the exploitative wage relationship between capitalist and labourer, by which all profit accrued to the capitalist. To counteract the uneven playing field between employers and employed, they proposed "schemes of labour notes based on labour time, thus institutionalizing Owen's demand that human labour, not money, be made the standard of value."<ref>{{cite book|last=Harrison|first=John|title=Quest for the New Moral World: Robert Owen and the Owenites in Britain and America|url=https://archive.org/details/questfornewmoral00harr|url-access=registration|year=1969|publisher=Charles Scibners Sons|location=New York|page=[https://archive.org/details/questfornewmoral00harr/page/72 72]}}</ref> This alternate currency eliminated price variability between markets, as well as the role of merchants who bought low and sold high. The system arose in a period where paper currency was an innovation. Paper currency was an [[I.O.U.|IOU]] circulated by a bank (a promise to pay, not a payment in itself). Both merchants and an unstable paper currency created difficulties for direct producers. An alternate currency, denominated in labour time, would prevent profit taking by middlemen; all goods exchanged would be priced only in terms of the amount of labour that went into them as expressed in the maxim '[[Cost the limit of price]]'. It became the basis of exchanges in London, and in America, where the idea was implemented at the [[New Harmony, Indiana|New Harmony]] communal settlement by [[Josiah Warren]] in 1826, and in his Cincinnati 'Time store' in 1827. Warren ideas were adopted by other Owenites and currency reformers, even though the labour exchanges were relatively short lived.<ref>{{cite book|last=Harrison|first=John|title=Quest for the New Moral World: Robert Owen and the Owenites in Britain and America|url=https://archive.org/details/questfornewmoral00harr|url-access=registration|year=1969|publisher=Charles Scibners Sons|location=New York|page=[https://archive.org/details/questfornewmoral00harr/page/73 73]}}</ref> In England, about 30 to 40 cooperative societies sent their surplus goods to an "exchange bazaar" for direct barter in London, which later adopted a similar labour note. The British Association for Promoting Cooperative Knowledge established an "equitable labour exchange" in 1830. This was expanded as the National Equitable Labour Exchange in 1832 on Grays Inn Road in London.<ref>{{cite book|last=Harrison|first=John|title=Quest for the New Moral World: Robert Owen and the Owenites in Britain and America|url=https://archive.org/details/questfornewmoral00harr|url-access=registration|year=1969|publisher=Charles Scibners Sons|location=New York|pages=[https://archive.org/details/questfornewmoral00harr/page/202 202–4]}}</ref> These efforts became the basis of the British cooperative movement of the 1840s. In 1848, the [[socialist]] and first self-designated [[anarchist]] [[Pierre-Joseph Proudhon]] postulated a system of ''time chits''. Michael Linton this originated the term "local exchange trading system" ([[LETS]]) in 1983 and for a time ran the [[Comox Valley, British Columbia|Comox Valley]] LETSystems in [[Courtenay, British Columbia]].<ref>{{Cite web |url=http://wiki.ashevillelets.org/wiki/What_is_LETS%3F |title="What is LETS?".

For instance, a member may earn credit by doing childcare for one person and spend it later on carpentry with another person in the same network. In LETS, unlike other [[local currency|local currencies]], no [[scrip]] is issued, but rather transactions are recorded in a central location open to all members. As credit is issued by the network members, for the benefit of the members themselves, LETS are considered [[mutual credit]] systems. ====Local currencies==== The first exchange system was the Swiss [[WIR Bank]].

Several major cities in the U.S. and Canada do not currently have a local [[barter exchange]]. There are two industry groups in the United States, the National Association of Trade Exchanges (NATE) and the International Reciprocal Trade Association (IRTA).
