It is an action in which two individuals decide to exchange two objects, of similar value, to simulate a sale and purchase, but obtaining a benefit other than monetary. Today, the term exchange is related to exchanging a certain certificate for an object; An example of this is buying certain products with coupons, which is an extreme case, it could lead to the total impersonation of money, receiving everything for free. A similar situation, too, is that of stamp books, which must be filled out completely to receive a prize for it. In both, what happens is an exchange, but adapted to current needs and social development.
In past times, the exchange, also known as barter, was used as a simple economic system throughout a territory, since the peoples that had not yet experienced the arrival of the currency tried to create a commercial model that would conform to the items they had available at the time. Humans who resided during the Neolithic were the ones who developed this model of exchange, which was later used by Egyptian, Greek and Roman civilizations in their early days.
The natives, for their part, dispensed with this before the arrival of the Spanish. They used it as a means of obtaining the necessary resources to live comfortably; for example, they exchanged some food items for handmade decoration elements. From the economic point of view, barter is an activity that requires the express approval of the two individuals who will participate, in addition to each one valuing the object to be delivered much more than the one they will receive. In the Marxist model, however, it is believed that the two elements are equal in value.
