EXIOMOD is a Computable General Equilibrium Model (CGEM). It therefore takes into account the interaction and feedbacks between supply and demand. Demand for products is created by sectors, households, exports and other final consumers. On the other hand, supply includes domestic production and imports. Prices and quantities are flexible and adjust within each time period to clear every market.

EXIOMOD model is particularly well suited to evaluate the impact of policies related to climate change and resource efficiency at the macroeconomic, sector and household levels:

  • Environmental extensions allows for measuring the impact of various economic activities on emissions and water, land and resource use.
  • The global coverage including trade flows allows for analyzing the impact of various economic activities on the environmental indicators in other countries. This feature is particularly convenient to estimate footprints per country.
  • The modular approach allows for separating direct and indirect effects, and in particular rebound effects.

EXIOMOD’s name stands for EXtended Input-Output MODel. “Extended” is this case refers to the fact that EXIOMOD can extend the standard Input-Output (IO) analysis in two main directions: (1) to general equilibrium analysis, and (2) to specific topics such as climate, energy, agriculture or transport. The latest specification of the model, EXIOMOD 2.0, is based on a modular approach specifically designed to conduct both input-output analysis and general equilibrium (CGEM) simulation. Depending on the subject under investigation, the modeler can easily change the regional and sectorial segmentation as well as the level of complexity regarding the specification of the model by switching on or off specific blocks. In addition, new blocks of the model can be developed, for example covering a specific market, and integrated with the existing structure of the model.

EXIOBASE is the current underlying database for EXIOMOD. With the full potential of the database the model covers 43 countries, five rest of the world regions, 163 sectors and 200 products. The product classification has great detail in particular on energy, resources and agricultural products. The graph shows the coverage of individual countries in EXIOMOD, as well as the schematic representation of global markets.
