> To be more precise: it depends on how the variables in your model are measured. As @stepan-a says, Dynare conducts a linearization. If you for example have a nonlinear model and your model variable is simply the level of output, the IRF will measure the difference between the variable and its steady state (or its mean at higher order). This is the case with [https://github.com/DynareTeam/dynare/blob/master/examples/example1.mod](https://github.com/DynareTeam/dynare/blob/master/examples/example1.mod) In contrast, if your model variable already measures percentage…
