IRF of models solved by extended path method

Postby jill1009 » Thu Oct 04, 2012 6:22 pm

Hi,
I am using dynare 4.3.0 to solve a DSGE model with zero lower bound. I use the extended_path command, but there is no option on impulse responses for that command. How could I get the impulse response of the model solved using the extended path method?
Thanks a lot!
Jill

By construction, an IRF using the extended path method is equal to a deterministic simulation where there is a shock in period 1 and no shock after.

So the fact that we did not provide IRFs for extended_path is deliberate. You can already compute them using the "simul" command.

Sebastien: It might be useful to support computing average IRFs from multiple simulations of the extended path algorithm. My suggestion would be to remove the extended_path command and perform the same functions if order is set to 0.
