Determinacy/indeterminacy/non-existence regions

Hi,

I was wondering whether it is possible to plot a 2D graph showing determinacy/indeterminacy/non-existence regions (as a function of, say, two policy parameters) with Dynare. Is there any code I can refer to?

Thanks a lot for your help!

Hi dome, there is no functions in Dynare to do what you want. You have
to code it yourself, writing a loop in the mod file where you change the values of some deep parameters. I never used this toolbox, but you may find what you want in Marco Ratto’s sensitivity analysis toolbox for dynare.

Best, Stéphane.

thanks stephane, I’ll have a look at that!

Hi Stéphane, I have a question on a related topic.
I want to create a loop on 2 parameters in the .mod file in order to plot the 2d determinacy region of my model. My question is: where does dynare save the eigenvalues? I need to recall them in order to check for the B-K conditions and then plot my results. Am I right? Is there maybe a shorter way to do the same thing?

I thank you in advance for your reply

Best regards

Gman
