Dynare forums

Hi,
I'm trying to run a deterministic simulation of an OLG model.
Blanchard-Khan conditions are verified but I get the following message from Dynare :

"variable Dif period 1
1- err = 0.35502
err_f = 0.51026
Time of this iteration : 0.266
variable gr period 2
2- err = 0.033397
err_f = 0.079035
Time of this iteration : 0.235
variable gr period 2
3- err = 0.00076967
err_f = 0.0046939
Time of this iteration : 0.235
variable gr period 2
4- err = 2.5182e-006
err_f = 1.4305e-005
Time of this iteration : 0.235

Total time of simulation : 1.062

Convergence achieved."

What does it means?
In particular:
why does Dynare report the name of some variables?
what is err_f and why do I get "convergence achieved" and not "convergency obtained"?
is there something wrong with the convergence of the model?

Thank you very much,
Best,

Alessandro

This is some debugging output that has now disappeared from the current versions. If I remember correctly, the variable name and period was indicating which variable in which period was most changed by the current Newton iteration.

Dear Michel,
Thank you very much for your reply.
I'm glad to know that the messages I get are not related to a convergency problem of the code I wrote.

However I'm using Dynare version 3.064, that should be the last one of the "Dynare3 series".

Has this kind of output (which only appears when I use a variable with lead 2) been changed in version 4 ?

You are right. This form of output is still used in both versions when there are lags on more than one period.

I will remove it one of these days as it is more confusing than anything else.

Thanks for reporting it

Best

Michel
