based mainly on the two data sources: regional I-O tables that provide intra-
regional industry coefficients for each state and interregional trade tables to provide
comparable trade coefficients. This implies the creation of three types of matrices:
an intraregional interindustry matrix, the interregional trade matrix, and the com-
bined interregional, interindustry matrix (in other words, the NIEMO matrix).
Before creating the matrices, however, the data reconciliation problem has to be
addressed.
The main steps involved in building and testing NIEMO are shown in Fig.

.
We developed the 47 USC sectors into which many of the other classification
systems can be converted. Figure

shows the industrial code conversion matrix
among the many data sources used in this study.
