Ecio Input-Output Relationships Generating Expected Output Series, Randall Jackson, Péter Járosi Jan 2020

Ecio Input-Output Relationships Generating Expected Output Series, Randall Jackson, Péter Járosi

Regional Research Institute Technical Documents

Generating expected output series is a critically important step in building Conway-type hybrid econometric input-output models. Because the RRI most often uses a modeling method that takes advantage of Jackson's Rest-of-World industry mechanism for representing imports in the Supply (Make) table rather than in final demand, we must insure that this method for generating historical expected output series will be consistent with the way in which future expected output is estimated (Jackson, 1998). This brief TechDoc lays out the relevant mathematical foundations. In so doing, we also identify the appropriate corresponding impacts assessment formulation.

Technical Document For Computing Coal Dependent Employment Estimates, Randall Jackson Apr 2017

Technical Document For Computing Coal Dependent Employment Estimates, Randall Jackson

Regional Research Institute Technical Documents

Object-Oriented Interindustry Systems: Proof Of Concept, Péter Járosi, Randall Jackson Aug 2015

Object-Oriented Interindustry Systems: Proof Of Concept, Péter Járosi, Randall Jackson

Regional Research Institute Technical Documents

This document provides a proof-of-concept demonstration of an object-oriented approach to modeling an inter-industry system. The example framework uses a small CGE model based on a three-sector social accounting matrix (SAM). The economy is shocked by changing total factor of productivity in the production function, the new equilibrium is determined in classical CGE fashion, and the original SAM is updated to conform to the new equilibrium solution. In this way, the efficiency of the Object-oriented modeling (OOM) approach can be emphasized in the context of the computational simulations of interindustry systems by a simplified CGE example written in Python. Since …

Disaggregating Input-Output Models, Xueting Zhao Oct 2014

Disaggregating Input-Output Models, Xueting Zhao

Regional Research Institute Technical Documents

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 represents all the input from common sectors into the new sectors. The second part is to calculate the disaggregated output matrix DOM, which represents all possible output weights of new sectors into common sectors. The last part is to calculate the intra matrix DINM, which represents the allocation of intra-industry sales in the …

Matlab Code For Structural Decomposition Analysis, Juan Tomas Sayago Gomez May 2014

Matlab Code For Structural Decomposition Analysis, Juan Tomas Sayago Gomez

Regional Research Institute Technical Documents

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 and Blair (2009) and Jackson and Schwarm (2011). The second stage (SDA.m) carries out the analysis and estimates the results based on the mathematical procedure in Yang and Lahr (2010) and Zhang and Lahr (2014). The end results can be exported into a csv file.

Generating Matlab Matrices From Implan Cge Files, Mason Pierce Mar 2014

Generating Matlab Matrices From Implan Cge Files, Mason Pierce

Regional Research Institute Technical Documents

This document describes the process used to create usable tables from the 27 individual GAMS files in .DAT format generated by IMPLAN software. 26 of these are social accounting matrix (SAM) data files and 1 is an employment-by-industry data file. By performing the appropriate command in MATLAB, the user can create the desired table, for example the use or make tables, which can then be used for various purposes. IMPLAN 2 and IMPLAN 3 produce .DAT files of different formats. This document details the process of handling each of these file formats.

An Aggregation Matrix Matlab Function, Caleb Stair Dec 2013

An Aggregation Matrix Matlab Function, Caleb Stair

Regional Research Institute Technical Documents

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 Ndimensional aggregation vector as an argument. The aggregation vector contains N values ranging from 1 to M, each of which is the aggregate index corresponding to the N preaggregation indices. The function returns an aggregation matrix with M rows and N columns. Pre-multiplying an existing matrix with N rows by the aggregation matrix reduces the row dimensionality from N to M by adding …

Resource Inventory And Assessment: Vision Shared Focus Team On Technology-Based Economic Development, Randall Jackson, Walter R. Schwarm, Russ Lorince, The Focus Team Jan 2006

Resource Inventory And Assessment: Vision Shared Focus Team On Technology-Based Economic Development, Randall Jackson, Walter R. Schwarm, Russ Lorince, The Focus Team

Regional Research Institute Technical Documents

West Virginia's overall competitive position in the area of technology-based economic development is characterized as mixed. While the state does have significant technology assets including federal research laboratories, universities and selected firms, these assets fail to produce substantial spillover benefits to the local population and state as a whole. While West Virginia has a relatively strong technological base, a number of factors serve to inhibit economic growth and technology transference.
