Editing Medium of exchange (section)

====Want of a measure of value====
A barter market theoretically requires a value being known of every commodity, which is both impractical to arrange and impractical to maintain. If all exchanges go 'through' an intermediate medium, such as money, then goods can be priced in terms of that one medium. The medium of exchange allows the relative values of items in the marketplace to be set and adjusted with ease. This is a dimension of the modern [[fiat money]] system referred to as a "[[unit of account]]."<ref>{{Cite journal|last1=KIM|first1=YOUNG SIK|last2=LEE|first2=MANJONG|date=2013-11-22|title=Separation of Unit of Account from Medium of Exchange |url=http://dx.doi.org/10.1111/jmcb.12066|journal=Journal of Money, Credit and Banking|volume=45|issue=8|pages=1685–1703|doi=10.1111/jmcb.12066|issn=0022-2879|url-access=subscription}}</ref>
