Question

Quizplus · Accepted Answer

A double coincidence of wants is necessary for barter exchanges. This means that in order for two parties to exchange goods or services directly without using money, they must each have a want for what the other is offering, creating a double coincidence of wants. This is not necessary for the use of money or for the use of credit or debit cards. It does not necessarily increase the number of exchanges taking place, as it can limit the potential for trade.
