MODEL SIMULATION for several values of a parameter

Dynare help (legacy posts)
1

Hi,
I would like to simulate a model with DYNARE by limiting the value of one parameter to a defined range (from 0.1 to 1.5, with 0.01 as size of increment) and extract the outcome for each value of this parameter within the range.
Please, Can you help me ? How to do that with dynare?
Any idea will be welcomed and appreciated.
Best,

Thank Jpfeifer, I will try to see it.

Dear Johannes,

I am trying to find moments and IRF of some variables when 2 and 3 policy parametrs change. I made the following loops in separate matlab-files, which run, but I need help in order to save and extract moments and IRF when the loop is over 2 or 3 parameters.

betha1s= 1.5:0.1:1.9;

for i=1:length(betha1s)

    betha2s=0.5:0.1:0.6;
    for j=1:length(betha2s)
        set_param_value('betha1',betha1s(i));
        set_param_value('betha2',betha2s(j));
        dynare pays_111_sP noclearall;
        moments(:,i)=diag(oo_.var);
      
    end

save(‘results_’,num2str(j)])

end

Questions: 1) This code runs, but not able to give me the moment change over parameter values (here, 10 variances). I get only 2 or 5 variances instead of 10. How to do that?
2) How can I save and call IRFs for some variables using the 2 loops?

This is not the correct way to do it. Please provide your files.

Please Johannes,
Herewith the files.

The attached file should do what you want.

Dear Johannes,
Thank you very much, this has been very helpful for me.

Dear Johannes,
Please if I will just extract the IRF for these 2-loops, I need to add which code line?
Best,

Maybe I’m missing something here, but you could just add a line that is of the form:

xirf(i)=oo_.irfs.C_eps_x(i)

where x is the shock of interest

Thank you,
But there are some things you missed, because i am looking for the 2 loops IRFs, like xirf(i,j).
Do you have any hints?

Something like:

Thank you Johaness, It seems to work.
