In economics, a price system is a component of any economic system that uses prices expressed in any form of money for the valuation and distribution of goods and services and the factors of production. Except for possible remote and primitive communities, all modern societies use price systems to allocate resources, although price systems are not used exclusively for all resource allocation decisions.[1]
A price system may be either a fixed price system where prices are administered by a government body, or it may be a free price system where prices are left to float "freely" as determined by supply and demand uninhibited by regulations. A mixed price system involves a combination of both administered and unregulated prices.
