IMACLIM-Country platform : a country-scale computable general equilibrium model

The computation of long term economic pathways and the assessment of sustainable development policies require models able to embark information and expectations from economists, engineers, earth scientists and stakeholders.

CIRED has drawn the architecture of modelling IMACLIM in order to cope with this scientific challenge at the interface of environment and development issues, in particular to assess climatic and energy policies. It relies on a hybrid model which combines a macroeconomic approach with sectional-engineers views. There are a regional scale version, IMACLIM-Country, and a world version IMACLIM-R

This code is related to the IMACLIM-Country version. It provides a common architecture to all the country versions under development.
Country versions mainly differ by the economic and physical accounts data that are fed to the platform, but can also consider alternative behavioural specifications and macroeconomic closure options. The modularity of the platform allows operating (i.e. hybridising data, calibrating and solving) at various levels of disaggregation of economic sectors and household groups, up to limits defined by each country’s original dataset.

New release of the IMACLIM-Country platform

Sum-up of the improvements

New technical features

• Selection of the country: flexibility to run IMACLIM on different countries by informing the set of calibration data. So far, the model can run on Argentina, Brazil and France:
  • France is calibrated at year 2010 as in previous version: recalibration for a more recent year under progress and data publication process
  • Brazil is calibrated at year 2015. Publication of data under progress.
  • Argentina is calibrated at year 2012. Publication of data under progress
• Selection of the number of step for resolution: possibility of a year-by-year resolution for prospective analysis
• Optimization of the resolution: time of runs and run robustness improved by alleviating the "fsolve" system

• Outputs: indicators /BY or year before, outputs with Python

  New Economic features

  • Border tax adjustment: possibility of added a carbon tax on country imports
  • Investment matrix: possibility of disaggregating the Investment column to distinguish which sectors are pushing the investment
  • Articulation with bottom-up model: intermediate consumption, capital consumption, labour or their respective intensities, as well as investment, coming from BU model can be "forced" into the resolution
  • Setting different uses of carbon tax revenues under public budget constraints: still under progress for new uses
  • Boundaries conditions for prospective exercises: exogenous information on import prices and on exports possibilities
