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.
Finding a way to make a profit from bartering isn’t just a challenge to the people putting up their livelihood for trade. Even the brokers who act as bartering middlemen are searching for creative ways to make money from a service that isn’t about making money. A website like Swap.com—which connects people who want to exchange their unused household items—looks, at least on paper, like a financial windfall. Jeff Bennett, Swap.com’s CEO, claims that “the business has been doubling every year.” They’re closing in on 450,000 registered users, who’ve taken part in more than 4 million barter exchanges valued at approximately $13 million since the site’s inception in 2010. But as no part of that $13 million is in actual money, how exactly does Swap.com cover its overhead? Most of its capital comes from “related aspects of the business,” says Bennett, such as shipping fees and corporate sponsorships. “We’ve had very good experiences with companies like Gallo wines, LuLu’s Clothing, and ModCloth.” He also hopes to introduce a Swap.com subscription service in the near future that offers customers incentives for forking over a monthly fee, like an ad-free environment and early access to their favorite items.
Other countries, though, do not have the reporting requirement that the U.S. does concerning proceeds from barter transactions, but taxation is handled the same way as a cash transaction. If one barters for a profit, one pays the appropriate tax; if one generates a loss in the transaction, they have a loss. Bartering for business is also taxed accordingly as business income or business expense. Many barter exchanges require that one register as a business.
For one thing, the barter myth “makes it possible to imagine a world that is nothing more than a series of cold-blooded calculations,” writes Graeber in Debt. This view is quite common now, even when behavioral economists have made a convincing case that humans are much more complicated—and less rational—than classical economic models would suggest.
It’s hard to answer that without actually seeing a modern gift economy in action. Luckily, modern gift economies actually do exist. On a small scale, they exist among friends, who might lend each other a vacuum or a cup of flour. There’s even an example of a gift economy on a much larger scale, albeit one that’s not always in operation: The Rainbow Gathering, an annual festival in which about 10,000 people gather for a month in the woods (it rotates among various national forests around the country each year) and agree not to bring any money. Groups of attendees set up “kitchens,” in which they prepare and serve food for thousands of people every day, all for free. Classical economists might guess that people would take advantage of such a system, but, sure enough, everyone is fed, and the people who don’t cook play music, set up trails, teach classes, gather firewood, and perform in plays, among other things.
