Just a quick question, what is the difference between the default “relative _irf” command of Dynare and the IRF used to replicate Schmitt-Grohe Uribe (2003) by Johannes Pfeifer? They are both normalizing to a unit shock size, but they are not exactly the same.
They are not the same, because in github.com/JohannesPfeifer/DSGE … U_2003.mod the law of motion for the exogenous process is
Thus, the standard deviation of the shock in the AR-process is not set in the
block, but rather corresponds to
Dynare does not know this and thus cannot use the
to construct a “true” unit shock.
