A USER'S GUIDE TO CONSTRAINED BIPROPORTIONAL MATRIX ESTIMATION

This report is one of a series being written for the University Research Program, U.S. Department of Transportation, to present analyses of the results obtained using the multiregional input-output (MRIO) model for the United States. The present report contains a guide to a number of computer programs that are used to adjust the set of multiregional input-output trade flows to be consistent with control totals from the regional input-output tables. It is based upon research completed by Malte Mohr and reported in his Ph.D. thesis, which is entitled "A Consistency Problem of Multiregional Input-Output (MRIO), and Existence Conditions of Constrained Biproportional Matrices."
