The term price system is used to describe any economic system whatsoever that effects its distribution of goods and services by means of goods and services having prices and employing any form of debt tokens, or money. Except for possible remote and primitive communities, all modern societies use price systems to allocate resources. However, price systems are not used for all resource allocation decisions today. A variety of Non-market economics type proposals have been presented as alternatives to a price system such as Energy Accounting.
