Non-linear mod file with log-linear external file

Dear all,

Is it possible to write a model file (.mod file) in non-linear form and edit an external Steady State file in log-linear form?
If so, ther is any example of that?

Thanks a lot,

Dear Marco,

I do not understand what you mean here… The steady state is defined as a fixed point of the nonlinear dynamic model, and is, generally, a non linear function of the parameters. Why would you want to (log)linearize the steady state? Around which point in the parameter space?

That said, when a nonlinear solver (Newton like algorithm) is used to compute numerically the steady state, we solve a sequence of linear approximations of the static model. But this is done automatically by Dynare, and you do not need to provide an external steady state file in this case.
