Abstract

This paper develops further the Montias-Levine model for the material-balances process, and presents a stepwise aggregation process with full-cost price formation. It shows that stepwise aggregation speeds up the iterative process, and shows further that the Manove-Weitzman process is an important, but very special, version of the model presented here. Numerical experiments, using the Soviet 15- and 76-sector I-O tables, offer comparative degrees of convergence speed for various processes and verify that any process using stepwise aggregation is more efficient.
