Estimation of Commodity Price by Industry using Modified Rectangular Input-Output Table

An application of input-output frame together with commodity price table is one of the most powerful methods for estimating inter-industry freight flow. How to get/estimate a commodity price set is the major concern of the method. This paper estimates commodity price using the freight census data and modified rectangular inputoutput table including wholesale activities. Although each estimated commodity price by this study is impossible to be verified because of lack of real data, however it is confirmed that the aggregated prices by commodity sector were proved to be quite adequate comparing with price data sets from different two sources.
