I have two separate questions:
I want dynare to plot the IRF from two shocks hitting at the same time. How do I implement this? Let’s say the two shock processes are a=rhoaa(-1) + ea and b=rhobb(-1)+eb and I want a 10% shock to a and a 20% shock to b. (I don’t want plots of orthogonalized shocks, which seems to be what is usually plotted).
I have two models: a baseline one and an extended one (which naturally has more equations and some different parameter values). How do I make dynare plot both IRFs on the same set of axes? Should I put each model in a different .mod file? Then what?
