News A Mathematica package (2023) has been developed that aims to analyze the production cascades of a prioritized sector in a country using OECD input-output database. This package automates the computation of three key graph-theoretic measures used in the assessment of a given production system (or supply chain): the extraction of the upstream cascade of production linkages of a targeted sector, the identification of production layers surrounding the targeted sector, and the measurement of the upstream network resilience of the targeted sector. This package also facilitates the cross-country comparison of the upstream networks of a given targeted sector. In other words, given a set of countries, such as A, B, C, etc., one can compare the upstream networks of sector i in these countries. Policy analysis can then be carried out from a network perspective as opposed to traditional sector-based analysis of policies. Dr. Temel's new book entitled "Information and Innovation Systems Analysis: Actor-Based Approach" reflects upon the research and policy advice activities he has conducted over the last 12 years. It is forthcoming in very near future... More information available in forthcoming book page. MathCode has been tested to improve the performance of Mathematica eSNA software using very large matrices. The test has shown that in some cases, Mathematica Standard and Compiled versions of codes are performing better than the MathCode code. This is due to the data transfer time between MathCode and Mathematica. New trials are still conducted to improve the performance... eSNA: ECOREC successfully completed a project Estimation of System of National Accounts (SNA). More information available in eSNA page.
