David Graeber argues that the inefficiency of barter in archaic society has been used by economists since Adam Smith to explain the emergence of money, the economy, and hence the discipline of economics itself.[2] "Economists of the contemporary orthodoxy... propose an evolutionary development of economies which places barter, as a 'natural' human characteristic, at the most primitive stage, to be superseded by monetary exchange as soon as people become aware of the latter's greater efficiency."[3] However, extensive investigation by anthropologists like Graeber has since then established that "No example of a barter economy, pure and simple, has ever been described, let alone the emergence from it of money; all available ethnography suggests that there never has been such a thing. But there are economies today which are nevertheless dominated by barter."[4]

Her answer came, finally, in an unlikely place: at a bar on Robson Street in Vancouver during the Winter Olympics. It was close to midnight, and she was waiting in line for a drink. All around her, people were partying—except for the two women in front of her, who were dissecting the differences between tax-free savings accounts and RRSPs. Simmons barged in to their conversation. “What do you want to know about TFSAs?” she asked. “What’s your goal?” She pulled the two aside and, for 20 minutes, gave an impromptu finance session. As a gesture of thanks, the two women bought Simmons and her group a round of beer. “I can’t afford financial advice,” one of them told Simmons, “but at least I can give everybody here a beer.” Then, Simmons felt like a cartoon megawatt bulb appeared over her head. It is all you can do, she thought. It is all you can do. There, in the middle of the crowded bar, she blurted, “Oh my god! I’m bringing barter back!”
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 complete strangers.[14]

Trade in Skyrim is oversimplified and uninteresting. A particular type of merchant always has the same amount of gold and offers you the exact same prices as the same type of merchant in another part of the country. Merchants in small towns differ very little from those in the larger cities, and the only factors that affect price are your speech skill and any barter enchantments you might have.
It helped that she had something other people wanted. “If I had gone in and offered to bake a pie for a free night at their hotel,’ they’d probably have said ‘no.’ ” One Barter Babe, Carly Boyce, knitted Simmons an exact replica of a favourite hat Simmons had lost but luckily had a picture of herself wearing. When it came time for the trade, Boyce remembers feeling guilty because the hat was so easy for her to make, and she told Simmons so. Simmons laughed: it was incredibly easy, she told Boyce, for her to give financial advice. It was a funny conversation, Boyce says, but also one that gets at the essence of bartering: when money is taken out of the equation, value is a moving, customizable concept—and that’s just the way most barterers like it.
Yet after three years with the firm, she was dissatisfied. She was spending all her time advising millionaires when she wanted to work with average Torontonians, especially women. She couldn’t help noticing that most of her female friends were broke, confused and floundering. Online, her social media feeds were filled with panicky talk of recession budgets and empty wallets. There was one problem: those women couldn’t afford to pay her, and she certainly couldn’t afford to work for free. “I really wanted to do it,” she says, “but I couldn’t figure out a business model.”
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."[19] 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 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.
In recent years, barter has enjoyed a resurgence as a means of countering economic insecurity, unemployment and worker exploitation. The nature of modern-day work, the pervasiveness of the Internet and the rise of social networking have all contributed to its spread. Other examples of alternative economic systems include gift economies, sharing economies and time banks.
Economic historian Karl Polanyi has argued that where barter is widespread, and cash supplies limited, barter is aided by the use of credit, brokerage, and money as a unit of account (i.e. used to price items). All of these strategies are found in ancient economies including Ptolemaic Egypt. They are also the basis for more recent barter exchange systems.[17]
No academics I talked to were aware of any evidence that barter was actually the precursor to money, despite the story’s prevalence in economics textbooks and the public’s consciousness. Some argue that no one ever believed barter was real to begin with—the idea was a crude model used to simplify the context of modern economic systems, not a real theory about past ones.
Anthropologists have argued, in contrast, "that when something resembling barter does occur in stateless societies it is almost always between strangers."[6] Barter occurred between strangers, not fellow villagers, and hence cannot be used to naturalistically explain the origin of money without the state. Since most people engaged in trade knew each other, exchange was fostered through the extension of credit.[7][8] Marcel Mauss, author of 'The Gift', argued that the first economic contracts were to not act in one's economic self-interest, and that before money, exchange was fostered through the processes of reciprocity and redistribution, not barter.[9] Everyday exchange relations in such societies are characterized by generalized reciprocity, or a non-calculative familial "communism" where each takes according to their needs, and gives as they have.[10]
He would have heard of channels and sandbanks, of natural features of the land useful for sea-marks, of villages and tribes and modes of barter and precautions to take: with the instructive tales about native chiefs dyed more or less blue, whose character for greediness, ferocity, or amiability must have been expounded to him with that capacity for vivid language which seems joined naturally to the shadiness of moral character and recklessness of disposition. 

You can use bartering to cut costs with your small business or to reduce personal expenses. For example, a handyman can trade services with a hairstylist. Each person is still getting paid for their work, in a sense, and it can lead to referrals to cash-carrying customers without costing a penny. However, the essence of bartering is simply to trade something you have for something you want or need – and you can do this whether you are struggling financially or have a steady income.
Still, Adam Smith really did seem to believe barter was real. He writes, “When the division of labour first began to take place, this power of exchanging must frequently have been very much clogged and embarrassed in its operations,” and then goes on to describe the inefficiencies of barter. And Beggs says that many textbooks sloppily seem to endorse this viewpoint. “They sort of use that fairy tale,” he explains.
It was the fifth lasagna that did it. Three months into the project, Simmons had signed up over 80 Barter Babes, and every time she bartered her financial services, she seemed to get a lasagna in return. She was trying to shove yet another five-pound pasta dish into her freezer when the tears started to flow. “I don’t need another lasagna!” she yelled at her boyfriend. “I need a haircut! I need a bicycle!” She was overwhelmed with doubts about her bartering experiment: I’m so ridiculous. What the hell was I thinking? This whole thing is never going to work. Trades weren’t happening at the frequency she had anticipated, and Simmons was feeling depressed. She couldn’t afford a dye job at a salon, and she had started gaining weight. She’d gone from ballin’ to having $200 in her joint account.
Debts in the wir currency, assigned the same value as the Swiss franc, could be paid with sales to any member of the bartering circle: if a baker needed to “purchase” eggs and flour from a farmer, the baker could pay off the debt by “selling” baked goods to another wir member. The farmer, in turn, could use his newly acquired credit to “buy” his own needed items or services. Despite a bank-led campaign to discredit the system, wir stuck. Today, it has more than 60,000 business participants and does the equivalent of about $4.4 billion in annual trade.
