Looping over parameters - steady state

Hi everyone,
I know the topic has already been treated on this forum several times. I’m trying to loop over parameter over steady state and I used the following code, but it does not work ;

I woul be thankful for any help.

Dear hko,
the mod file loads loop3, but you didn’t provide us with such a file. Please, give us all the files that we need to run the code.

Dear Valerio,
Here you find the correct mod file and m. file:
paper2_loop.m (621 Bytes)
paper2.mod (5.5 KB)
Thank you so much for your help. :slight_smile:

Dear Selma, in line 85 of the mod file you load a mat file called paper2_loop: I do not have this mat file, I only have an .m file and a .mod file from you. So please, provide us all the files that we need in order to run your codes.

Sorry Valerio, as I am a beginner , I do not understand what you mean. Should I create a mat file?

No problem Selma. My question is the following: why do you need the command in line 85 of the mod file

load paper2_loop;

?

I want to loop parameters (taut and tauf) over steady state in order to study the tax policy effect , and reading some papers about dynare I understood that I have to create a m. file in parallel to mod file, for this reason I created the m file. https://www3.nd.edu/~esims1/using_dynare_sp15.pdf. But I think I misunderstood.

So the goal is to study how the steady state changes when taut and tauf change? I’ll try to help you.

yes, that’s it! Thank you so much for your help!!!

I did the loop directly in the mod file. Given that you know the exact steady state, you can specify:

steady_state_model;

instead of

initval;

In matrix SS you have all the steady-state vectors associated with a specific tax rate combination. But notice that you do not necessarily need Dynare: you know the steady state of the model, you want to do only a steady-state analysis, so you can simply use an m. file, without the need of listing all the equations of the model.

Thank you so much Valerio :slight_smile: .
