Using Dynare to calculate derivative


I am estimating a perfect foresight, OLG-type model, and is in need of calculating some partial derivatives. In particular, i want to obtain a partial derivative of an endogenous steady-state variable with respect to some parameter (i.e. derivative of steady-state production with respect to population growth/depreciation/…).

The model does not have an analytical solution for steady-state variables, or else i would (of course) have used that. Can dynare (or some matlab tool implementable in dynare) calculate this derivative?

Thanks, N.W

If you are able to solve the model with Dynare, you can do the comparative statics via finite differences, i.e. approximate the derivative/tangent by a secant. That you need to do manually, but it is straightforward.
