Coincidence of wants - Wikipedia, the free encyclopedia

Coincidence of wants - Wikipedia, the free encyclopedia: "The coincidence of wants problem (often 'double coincidence of wants') is an important category of transaction costs that impose severe limitations on economies lacking money and thus dominated by barter or other in-kind transactions. The problem is caused by the improbability of the wants, needs or events that cause or motivate a transaction occurring at the same time and the same place."
