 | | First described by Jevons (1875), double coincidence of wants relates to the fact that both traders, involved in an exchange transaction without a recognizable currency, should find the other agents offerings useful and desirable, which significantly reduces the probability that these mutually acceptable trades will occur. |
 | | However, it is not double coincidence of wants alone that justifies the emergence of money--or fiat currency--as a recognizable equivalent of value leading to more efficient economies. |
 | | Information and knowledge exchange on the Internet when no currency is involved are susceptible to the double coincidence of wants, a situation where transactions should be mutually agreeable for both agents participating in exchange and therefore, the frequency of such transactions will decrease. |
