Looping a model

[E.Ahmed]

Dear Professors and researchers,
You will observe that several times I ask looping questions.
In fact, despite your recommendations, I still have errors and I thought of sharing with you my code if it is possible to help me.
The code has defined the parameters, the equilibrium model, and this linearized.
I just detect the results when one of the tax rates (defined as variable tauc, taul, and tauk) varies from 0 to 1.

Sorry, but what is your question? There is no loop in the mod-file and it does not produce an error.

The problem is that I don’t know the technique to calculate the stationary state vector for T =1, 2, … 100

[jpfeifer]

You never clearly outlined what you are trying to do. What is T in this context? What do you mean with

stationary state vector
?

[E.Ahmed]

Stationary state vector represents the values of the variables at equilibrium. This vector can change when one or more parameters are changed. T represents the government revenues. My goal is to calculate the equilibrium vectors by changing a tax (declared as variable tauc) from 0 up to 100%. But I don’t know how to do it on Dynare.

Use

Loop over parameters

You are not actually setting the parameter. What you should do is use the the set_param_value command. Moreover, if you have an analytic steady state, use a steady_state_model block instead of initval. You can find an example for such a loop here: [Need help to check Matlab compatibility). Basically, you need to write a Matlab m-file with the following parts: rhos = 0.8:0.05:1.05; first_time = 1; for i=1:length(rhos) if first_time set_param_value('rho',rhos(i)); dynare your_…

I thank you Professor @jpfeifer for your time, and for a Help.
