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.

The Imaclim-R model (Sassi et al., 2010 1; Waisman et al., 20122), is a multi-region and multi-sector model of the world economy. It combines a Computable General Equilibrium (CGE) framework with bottom-up sectoral modules in a hybrid and recursive dynamic architecture. Furthermore, it describes growth patterns in second best worlds with market imperfections, partial uses of production factors and imperfect expectations.

Table 1 shows a list of references involving IMACLIM-R categorized as follows:

  1. References describing the structure and results obtained with the Imaclim-R Global model
  2. References to models comparison exercises in which Imaclim-R Global model has participated

The references in Table 1 are further divided by technology, behaviour etc. focus.
