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."[16] 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. 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.
Economists since the times of Adam Smith (1723-1790), looking at non-specific pre-modern societies as examples, have used the inefficiency of barter to explain the emergence of money, of "the" economy, and hence of the discipline of economics itself.[3] However, ethnographic studies have shown that no present or past society has used barter without any other medium of exchange or measurement, nor have anthropologists found evidence that money emerged from barter, instead finding that gift-giving (credit extended on a personal basis with an inter-personal balance maintained over the long term) was the most usual means of exchange of goods and services.[4]
As Orlove noted, barter may occur in commercial economies, usually during periods of monetary crisis. 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).[15]

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 whole point of barter is to satisfy a need. A valuable barter is whatever a barterer needs at that moment. Raj Dhiman, a 30-year-old chemist, joined Swapsity at the beginning of 2012. For his first barter, he traded a batch of home-baked gluten-free muffins in return for a full weekend first aid course. Unlike the course’s instructor, Dhiman relished the challenge of perfecting the recipe. Since then, he’s exchanged a lesson on how to create a website for an Indian cooking class. He’s also turned away barter offers that he didn’t find personal value in. “It’s perfectly fine to decline,” he says, “It wasn’t like, ‘Whoa, whoa, whoa. What is this person thinking?’ I’d say, ‘I appreciate the offer, but that’s not what I need right now.’ All you have to do is ask for what you need.”

When barter has appeared, it wasn’t as part of a purely barter economy, and money didn’t emerge from it—rather, it emerged from money. After Rome fell, for instance, Europeans used barter as a substitute for the Roman currency people had gotten used to. “In most of the cases we know about, [barter] takes place between people who are familiar with the use of money, but for one reason or another, don’t have a lot of it around,” explains David Graeber, an anthropology professor at the London School of Economics.
