The man who arguably founded modern economic theory, the 18th-century Scottish philosopher Adam Smith, popularized the idea that barter was a precursor to money. In The Wealth of Nations, he describes an imaginary scenario in which a baker living before the invention of money wanted a butcher’s meat but had nothing the butcher wanted.“No exchange can, in this case, be made between them,” Smith wrote.
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.
While Swapsity trades are facilitated online, its participants can be seen in real life at themed in-person swap meets as well as the annual Live Green Toronto Festival. Over the past three years, more than 25,000 items—primarily clothes, books, CDs and DVDs—have been swapped at its events, collectively saving people roughly $200,000. About 5,000 items have been donated to charity. On average, each participant saves $80 at every swap (the value of items they go home with and would have otherwise bought). This year’s Live Green event was packed despite the grey July weather: until it started to rain heavily in the late afternoon, lineups to get into the six swapping tents spanned the full length of the waiting area, then folded in on themselves like accordions. Even in the rain, the leaking tents bustled.

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.

Whether or not one agrees with such broad claims, it’s worth noting that monetary debt, a byproduct of currency, has regularly been used to by some groups to manipulate others. Thomas Jefferson, for instance, suggested that the government encourage Native Americans to purchase goods on credit so they’d fall into debt and be forced to sell their lands. Today, black neighborhoods are disproportionately plagued by debt-collection lawsuits. Even after taking income into account, debt collection suits are twice as common in black neighborhoods as in white ones. $34 million was seized from residents of St. Louis’ mostly black neighborhoods in suits filed between 2008 and 2012, much of which was seized from debtors’ paychecks. In Jennings, a St. Louis suburb, there was one suit for every four residents during those years. 

The Trade Brokers are what we call the windows to the system.  Their role is to assist an existing portfolio of clients in both the buying and selling of products and services.  The Trade Brokers are responsible to make sure that the clients they consult with are aware of barter opportunities that may be of interest to them which helps our clients grow thier business!
In Canada, barter continues to thrive. The largest b2b barter exchange is Tradebank, founded in 1987. P2P bartering has seen a renaissance in major Canadian cities through Bunz - built as a network of Facebook groups that went on to become a stand-alone bartering based app in January 2016. Within the first year, Bunz accumulated over 75,000 users[29] in over 200 cities worldwide.
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]
Nowinska says one of the biggest challenges Swapsity faces is that new barterers think they have nothing to offer. So they offer bad trades. Yet most people have hundreds of skills—from cooking to networking to scrapbooking. The trick is learning to recognize the value of your skills, your knowledge and your talent. Bartering attaches value to things that are not always recognized, or highly valued, in a cash economy—often hobbies that people can’t make a living on but love to do. One Barter Babe trades her homemade canned goods for gifts—mostly other crafted items—she can give away at Christmas. A Swapsity member has traded pounds of fiddleheads she picks at her mom’s house in the country for feng shui sessions. 

Modern barter and trade has evolved considerably to become an effective method of increasing sales, conserving cash, moving inventory, and making use of excess production capacity for businesses around the world. Businesses in a barter earn trade credits (instead of cash) that are deposited into their account. They then have the ability to purchase goods and services from other members utilizing their trade credits – they are not obligated to purchase from those whom they sold to, and vice versa. The exchange plays an important role because they provide the record-keeping, brokering expertise and monthly statements to each member. Commercial exchanges make money by charging a commission on each transaction either all on the buy side, all on the sell side, or a combination of both. Transaction fees typically run between 8 and 15%.
