How does money solve the problem of double coincidence of wants? Explain with an example of your own.
In a barter system where goods are directly exchanged without the use of money, double coincidence of wants is an essential feature. By serving as a medium of exchanges, money removes the need for double coincidence of wants and the difficulties associated with the barter system. For example, it is no longer necessary for the farmer to look for a book publisher who will buy his cereals at the same time sell him books. All he has to do is find a buyer for his cereals. If he has exchanged his cereals for money, he can purchase any goods or service which he needs. This is because money acts as a medium of exchange.
