Barter requires a double coincidence of wants. This means that individual A and individual B both want the same commodity. individual \( \mathrm{A} \) and individual \( \mathrm{B} \) both want money. if individuals \( \mathrm{A} \) and \( \mathrm{B} \) are to exchange a commodity, \( \mathrm{A} \) must want what \( \mathrm{B} \) has and \( \mathrm{B} \) must want what \( \mathrm{B} \) has. if individuals \( A \) and \( B \) are to exchange a commodity, B must want what \( B \) has and \( A \) must want what \( A \) has. if individuals \( \mathrm{A} \) and \( \mathrm{B} \) are to exchange a commodity, \( \mathrm{A} \) must want what \( \mathrm{B} \) has and \( \mathrm{B} \) must want what \( \mathrm{A} \) has
