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.
Michael Linton originated the term "local exchange trading system" (LETS) in 1983 and for a time ran the Comox Valley LETSystems in Courtenay, British Columbia. LETS networks use interest-free local credit so direct swaps do not need to be made. 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 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.
In 2012, the average Canadian had more than $27,000 in consumer debt. Wages are shrinking, costs are rising, and one-third of us are living paycheque to paycheque. “Most of us live beyond our means both financially and ecologically,” says Marta Nowinska, founder and president of one of Canada’s largest bartering communities, Swapsity, which launched in 2010. “Swapping is a viable approach to solving a lot of real problems,” she says. Like Simmons, Nowinska left a Bay Street job to join the world of barter. The idea for Swapsity came to her one day in 2006: she was on the subway and noticed how miserable everybody looked. She started to think about a business that could empower people. At first, she thought people could swap jobs, but dismissed it as unrealistic. Then: what if they could swap other things? She developed a business plan and launched a website.
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.
