Natural economy refers to a type of economy in which money is not used in the transfer of resources among people. It is a system of allocating resources through direct bartering, entitlement by law, or sharing out according to traditional custom. In the more complex forms of natural economy, some goods may act as a referent for fair bartering, but generally currency plays only a small role in allocating resources. As a corollary, the majority of goods produced in a system of natural economy are not produced for the purpose of exchanging them, but for direct consumption by the producers (subsistence).
