Dear all,

I solve my model for the optimal discretionary policy and I am trying to store the value of the planner objective function. I get the following error message:

Reference to non-existent field 'planner_objective_value'.

I use the dynare version 4.4.3. I have run the model diagnostics and they give back nothing (probably there is no mistake in the model).

Best,

Nikos

Please try the unstable version.

Dear Johannes,

I installed the unstable version, then opened matlab and typed addpath /usr/local/opt/dynare/lib/dynare/matlab. I still get the same error message "Reference to non-existent field 'planner_objective_value'."

I don't know if it is relevant, but when I type the addpath /usr/... I get the following warning message:

Warning: Function bsxfun has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name
conflict.
> In path at 109

Thank you a lot,

Please let me say, that I figured out that this problem holds only under discretionary policy. I solved the Ramsey problem with the stable version and the command for the value of the objective function works.

Please provide the file to replicate the issue. This sounds like a bug.

Please find attached the mod file.

The reason is that we do not save the objective function value for discretionary policy. We are going to change that in the future, see https://github.com/DynareTeam/dynare/issues/1041

Thank you very much for raising this issue .

Just to let you know, I tried to include the

oo_.planner_objective_value = evaluate_planner_objective(M_,options_,oo_);

to the discretionary_policy.m file and then I run the model again. I got the following error

Undefined function or variable "yhat2".
Error in evaluate_planner_objective (line 95)
yhat2 = yhat2(dr.order_var(nstatic+(1:nspred)),1)-dr.ys(dr.order_var(nstatic+(1:nspred)));
Error in discretionary_policy (line 39)
oo_.planner_objective_value = evaluate_planner_objective(M_,options_,oo_);

Thank you again.

You need to change that file according to https://github.com/JohannesPfeifer/dynare/commit/cc3aeafd00f5135425dcc869e54a9c99c1e20790

Yes, I made the changes. It works perfectly. Thank you a lot for this.
