Abstract: The aggregation of industry sectors in input-output modeling is a common step in a regional analysis process. The author develops an optimization-based approach for identifying aggregation schemes which minimize the resulting error or information loss. Example problems previously reported in the literature are utilized for demonstrating the effectiveness of this approach and point out the shortcomings of previously reported results.
