Barter is the direct exchange of goods or services without using money as the medium of exchange.
Why economists discuss barter
Barter helps explain why money is useful. Direct exchange can work in small settings, but it becomes cumbersome when traders must find partners who both want what they offer and offer what they want in return.
The key problem
This difficulty is known as the double coincidence of wants. Money solves it by acting as a generally accepted medium, making exchange easier and specialization more extensive.
Why barter still matters
Barter has not disappeared completely. It can reappear in informal settings, periods of instability, or special business arrangements. Economists use it mainly as a contrast case to show the transaction-cost advantages of money.
