Dynare Steady State Toolbox

This toolbox provides a set of matlab routines that translate a matlab routine computing the steady state of a DSGE model into something readable by dynare (i.e. conforming to what is expected in a *_steadystate2.m file generated by Dynare from the equations in the steady_state_model model block). Examples are provided in the tests subfolder. Assuming that the dynare/matlab folder is in the Matab/Octave's path, you just need to add the src subfolder in the path:

>> addpath TOOLBOXES_PATH/dynare-steadystate-toolbox/src

where TOOLBOXES_PATH is the path to the folder where you unziped the steadystate toolbox.

Compared to what Dynare does with the steady_state_model, this toolbox is far less efficient than Dynare in producing the *_steadystate2.m routine. The advantage is the additional flexibility. The user can use any matlab statement in the source file (loops, conditional constructs, fixed point routines, ...), add traps and/or return custom error flags. Note that the routine produced by this toolbox is as efficient as the one produced by Dynare from the steady_state_model block (only the generation of the *_steadystate2.m is slower, because this is done in Matlab/Octave rather than by the C++ preprocessor). The relative cost associated to the generation of the *_steadystate2.m is generally very marginal, when the model has to be estimated, or when one performs Monte Carlo analysis to elicite the prior distributions.
