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." 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.
While one-to-one bartering is practiced 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.
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.
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!”
Since the 1830s, direct barter in western market economies has been aided by exchanges which frequently utilize alternative currencies based on the labor theory of value, and designed to prevent profit taking by intermediators. Examples include the Owenite socialists, the Cincinnati Time store, and more recently Ithaca HOURS (Time banking) and the LETS system.
