Solution concept General equilibrium (closed economy)
Solution method SimulationImaclim-R is implemented in Scilab, and uses the fonction fsolve from a shared C++ library to solve the static equilibrium system of non-linear equations.
Anticipation Recursive dynamics: each year the equilibrium is solved (system of non-linear equations), in between two years parameters to the equilibrium evolve according to specified functions.

Technological change is represented in a variety of ways in Imaclim-R:

  • For technologies that are explicitly represented, i.e. power generation technologies there are cost-reducing learning-by-doing factors. See Section on electricity and private vehicles (see Section on transport.
  • For sectors where explicit portfolios of technologies are not represented, the model nonetheless covers (price induced) endogenous energy efficiency improvements and substitutions with other sectors. See Section on productive sectors.
