This Technical Document describes the steps to disaggregate an industry sector in an I-O table using Python. A disaggregation method that based on weight factors is used in this document. The calculation has three parts. The first part is to calculate the disaggregated input matrix DIM, which...

The conventional input-output model has been widely criticized, both justly and unjustly, for its limiting assumptions. One of these assumptions is homogeneity of degree one. This paper explores some approaches to minimize this limitation of traditional input-output analysis by removing the...

This brief note draws further attention to cross-hauling in regional input-output table estimation, and specifically identifies conceptual issues associated with Kronenberg?s CHARM method for adjusting input-output regionalization methods. Despite the shortcomings of the CHARM approach as it now...

Although the literature has provided steps in the right direction, conceptual shortcomings still exist in the cross-hauling adjustment methods that are currently being applied in the literature. This paper represents an attempt to 1) characterize the cross-hauling adjustment methods that exist...

This Technical Document describes the foundations for an aggregation matrix function implemented in MATLAB, including the format and structure of the required aggregation vector used as an argument to the function. The function is passed with the N-dimensional aggregation vector as an argument....

This TechDoc describes the steps necessary to apply the Structural Decomposition Analysis (SDA) using Matlab. The code has two stages. The first stage, which comprises PrepSDA.m and RAS_SDA.m, prepares the data and the input required for SDA based on the accounting identities defined in Miller...

Although Input-Output (IO) models are widely accepted tools for regional scientists and economists alike, there are still many issues to confront during their application, including estimating impacts relative to future years, dynamic impacts, and the introduction of new technologies within...
