A Technique to Obtain Accurate Impact Multipliers for Individual Firms by Means of Existing Input—Output Models

A low-cost technique is developed that allows individual firms and establishments to estimate accurately their output, income, and employment multipliers by integrating their regional coefficients (the proportion of the purchases of a firm from each sector of the regional economy) with an existing regional input-output model. The empirical tests of this method on three actual survey-based input-output models produced excellent results.
