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]

In Spain (particularly the Catalonia region) there is a growing number of exchange markets.[20] These barter markets or swap meets work without money. Participants bring things they do not need and exchange them for the unwanted goods of another participant. Swapping among three parties often helps satisfy tastes when trying to get around the rule that money is not allowed.[21]

In England, about 30 to 40 cooperative societies sent their surplus goods to an "exchange bazaar" for direct barter in London, which later adopted a similar labour note. The British Association for Promoting Cooperative Knowledge established an "equitable labour exchange" in 1830. This was expanded as the National Equitable Labour Exchange in 1832 on Grays Inn Road in London.[21] These efforts became the basis of the British cooperative movement of the 1840s. In 1848, the socialist and first self-designated anarchist Pierre-Joseph Proudhon postulated a system of time chits. In 1875, Karl Marx wrote of "Labor Certificates" (Arbeitszertifikaten) in his Critique of the Gotha Program of a "certificate from society that [the labourer] has furnished such and such an amount of labour", which can be used to draw "from the social stock of means of consumption as much as costs the same amount of labour."[22]
You can use bartering to cut costs with your small business or to reduce personal expenses. For example, a handyman can trade services with a hairstylist. Each person is still getting paid for their work, in a sense, and it can lead to referrals to cash-carrying customers without costing a penny. However, the essence of bartering is simply to trade something you have for something you want or need – and you can do this whether you are struggling financially or have a steady income.

Inevitably some people may feel like they were taken advantage of. One way to diminish inequities is to engage in dollar-for-dollar trades. For example, if you would like to trade your housecleaning service for someone’s couch, try to break down the goods and services to the dollar amount. If the two of you decide that the value of the couch is worth $200, why don’t you supply a gift certificate for $200 worth of housecleaning services? It’s a wise course and ensures all parties know what they are getting and what they are offering.
It is estimated that over 450,000 businesses in the United States were involved in barter exchange activities in 2010. There are approximately 400 commercial and corporate barter companies serving all parts of the world. There are many opportunities for entrepreneurs to start a barter exchange. Several major cities in the U.S. and Canada do not currently have a local barter exchange. There are two industry groups in the United States, the National Association of Trade Exchanges (NATE) and the International Reciprocal Trade Association (IRTA). Both offer training and promote high ethical standards among their members. Moreover, each has created its own currency through which its member barter companies can trade. NATE's currency is the known as the BANC and IRTA's currency is called Universal Currency (UC).[28]

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.
On the positive side, there are great advantages to bartering. As mentioned earlier, you do not need money to barter. Another advantage is that there is flexibility in bartering. For instance, related products can be traded such as portable tablets in exchange for laptops. Or, items that are completely different can be traded such as lawn mowers for televisions. Homes can now be exchanged when people are traveling, which can save both parties money. For instance, if your parents have friends in another state and they need somewhere to stay while on a family vacation, their friends may trade their home for a week or so in exchange for your parents allowing them to use your home.
