How Eora is Built

There are two main academic papers presenting how Eora was constructed. The Supplementary Information for the "Mapping the Structure" paper contains a considerable amount of detail, including which data source(s) were used for building which IO tables.

Lenzen, M., Moran, D., Kanemoto, K., Geschke, A. (2013) Building Eora: A Global Multi-regional Input-Output Database at High Country and Sector Resolution. Economic Systems Research, 25:1, 20-49, DOI:10.1080/09535314.2013.769938

We also provide a document explaining the constrained optimization approach used to merge and reconcile multiple, often conflicting, data sources into a single balanced MRIO: EoraConfidence.pdf

On the horizon for development of future MRIO database is the Virtual Industrial Ecology Laboratory concept. This is a web-based platform where IO researchers from around the world can contribute and link IO data toward the construction of the next generation of global MRIO databases.

MRIO model intercomparison

Several MRIO models exist. There is variation in the CBA results across models, but this variation is generally considered acceptable. For more on intercomparison see:

D. Moran, Wood, R. (2014) Convergence between the Eora, WIOD, EXIOBASE, and OpenEU's consumption-based carbon accounts. Economic Systems Research. DOI:10.1080/09535314.2014.935298

Another intercomparison website is the Environmental Footprints Explorer .

Learning MRIO

Below is a list of resources (papers, reports, and video) that can help in learning basic IO analysis.

The Eora for Dummies guide has fallen a bit out of date (it refers to an earlier version of this website) but may still be useful for helping to get oriented with Eora.

Additional papers

Most of the main papers presenting Eora and Eora-based results are provided above and in the individual applications sections (e.g. for carbon, water, and biodiversity footprints). We have also contributed to a number of additional papers related to the construction or use of MRIOs:
