Value Chains: Production Upstreamness And Downstreamness Revisited, Patricio Aroca, Randall Jackson
Value Chains: Production Upstreamness And Downstreamness Revisited, Patricio Aroca, Randall Jackson
Regional Research Institute Working Papers
Measures devised to quantify value chain position have been used increasingly in recent years. While the constructs underlying these measures are meaningful, this paper identifies an overlooked implementation problem. Proposed algorithms have been applied as though the underlying data represent flows. Implementation data are drawn from modern input-output accounting frameworks that recognize secondary production explicitly. Unadjusted Use matrices are not conventional flows matrices because they do not identify the industries from which commodities originate. We demonstrate logical inconsistencies that arise, provide correct flow matrix formulations for upstreamness and downstreamness measures, and present empirical comparisons of correct and incorrect formulations.
Object-Oriented Interindustry Systems: Proof Of Concept, Péter Járosi, Randall Jackson
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
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 …

Technical Document For Price Adjustment, Zheng Tian, Mulugeta Kahsai, Randall Jackson
Technical Document For Price Adjustment, Zheng Tian, Mulugeta Kahsai, Randall Jackson
Regional Research Institute Technical Documents
This document presents the basis for the price adjustment mechanisms in a time series IO model. The essentials of the price adjustment and price change propagation algorithms are presented, along with a matrix permutation algorithm that facilitates the implementation of the price adjustment mechanism. The Matlab function is provided.
