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:

• There is cost-reducing learning-by-doing factor for technologies that are explicitly represented, i.e. power generation technologies. 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.

• Moreover, the model includes inertias and path-dependencies, via capacity stocks (capital generations), as well as constraints on the maximal speed of technology deployment.

• The current version of the model uses exogenous trends in labor productivity to model exogenous technical change of labor. See Section on economic growth.
