Commodity transactions in the
input-output
(I-O) accounts are valued in producers' prices in order to show
the relationship between the production of commodities and their
purchase by intermediate and
final
uses. These prices exclude wholesale and retail trade
margins and transportation costs, but they include sales and excise taxes
collected and remitted by producers. Transportation costs and
wholesale and retail trade margins are treated separately as
commodities that are produced by industries and purchased by
intermediate and final users. Related terms:
intermediate
purchases.
