Specialization is encouraged, because people whose output is not a complete product but only a part of one can be paid an amount equivalent to their share of the product.

Another advantage of money is that it is a measure of value. In a barter economy it would be necessary to determine how many plates were worth one hundred weight of cotton, or how many pens should be exchanged for a ton of coal.

The process of establishing relative values would have to be undertaken for every act of exchange, according to what products were being offered against one another, and according to the two parties’ desires and preferences.

Thirdly, money acts as store of wealth. It is difficult to imagine saving under a barter system. No one engaged on only one stage in the manufacture of a product could save part of his output, since he would be producing nothing complete. Most products deteriorate fairly rapidly, either physically or in value, as a result of long storage; even if storage were possible, the practice of storing products for years on end would involve obvious disadvantages. If wealth could not be saved, or only with great difficulty, future needs could not be provided.
