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...

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...

Input-output analysts are often confronted with requests for impacts assessments for economic shocks that stretch uncomfortably the assumptions of standard input-output modeling. This paper presents an approach to confronting a subset of these challenges straightforwardly in a way that...

Several procedures for generating interregional commodity flow matrices have been developed in the U.S. in recent years (see, e.g., Canning and Wang in J. Reg. Sci. 45, 539–563, 2005, Jackson et al. in Ann. Reg. Sci. 40, 909–920, 2006, Lindall et al. in J. Reg. Anal. Policy 36, 76–83,...

We use a regional input output (IO) framework and data derived on waste generation by industry to examine regional accountability. In addition to estimating a series of industry waste-output coefficients, the paper considers a series of methods for waste attribution, and practical use for...

A number of procedures for generating interregional commodity by industry accounts have been developed recently (Canning and Zhi, 2005; Robinson and Liu, 2006; Jackson et al, 2006; Lindall, Olsen and Alward 2006). While each approach shares a common organizational framework, very little attention has been...

To explore choices of improving energy efficiency in energy-rich countries of the Middle East, this study lays out an integrated modeling framework for analyzing the technology-energy-environment-economy chain for the case of an energy exporting country. This framework consists of an input...

This paper reports our efforts to develop a baseline input-output model with environmental accounts for use in developing geographically specific e-waste recycling systems. We addressed the conceptual and practical issues that occurred when the recyclable end-of-life commodities and related...

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...
