As a medium of exchange, money permits the separation of exchange into the two distinct acts of buying and selling, without requiring the seller to purchase goods from the person who buys his products, or vice versa. Hence producers who know they will be paid in money, can concentrate on finding the most suitable outlet for their goods, while buyers who will pay in money, can concentrate on finding the cheapest market for the things they wish to purchase. specialization, which is vital to an advanced economy, is encouraged, because people whose output is not a complete product but only a part of one in which many others are involved can be paid an amount equivalent to their share of the product.
Another advantage of money is that it is a measure of value -- that is, it serves as a unit in terms of which the relative values of different products can be expressed. In a barter economy it would be necessary to determine how many plates were worth one hun
