Full Eora

This page provides the entire Eora MRIO for download. For each year there are ten sheets: one values matrix and one standard deviations matrix for each of the five price margins (Basic prices, trade markup, transport markup, taxes markup, and subsidies markup). A guide to the Eora MRIO structure is here: Eora26Structure.xlsx.

Metadata

Download indices.zip contains the country codes and sector names. The Satellite accounts Q use index_q for row labels and index_t then index_y for columns labels.

The MRIO is provided broken into the four constituent blocks:

• The transactions matrix T (note: in some IO literature this is called the flows matrix and denoted as Z)
• The primary inputs block V (note: in some IO literature this is called the Value Added block)
• The final demand block Y
• The satellite accounts Q which provde the environmental, social, and other nonmonetary inputs to production

In the satellite account block rows are satellite line items as documented in index_q.csv. The first 1:T-dim columns are inputs to industry, and the T-dim+1:end columns are direct emissions associated with housholds, government, etc, following the column layout of index_y.csv.

Data Versions

We periodically release updated datasets. It is recommended that you store these data in a folder named with the current version number: v199.82.

MATLAB Utility Object

We offer a utility class to help navigate the MRIO structure. It is called a tree structure, since the MRIO can be thought of as organized in a hierarchical tree structure (Year -> Margin -> Country -> Ind|Com|FD|PI|Q -> Sector). This object contains sector labels, indexing information, country names, and so on. To use it you need two files:

Usage:

load('c:\path\to\the\vv199.82\tree_structure.mat');tr=obj;
disp(tr.countries);
doc tree_structure

% How to locate a particular sector
co = tr.a3('ITA'); % find country number for Italy
inds = tr.indexT{co}; % find row and column indices for Italy. Also see tr.indexM and tr.indexYV.
sec = inds(2); % Location of sector 2 in italy
disp(tr.labsT(sec,:)); % Confirm you arrived at the right location.
