Dear Professors and Colleagues, Once again, I come here to ask for your help. I wanted to estimate the Laffer curve in my DSGE analysis. Some of you suggested me to review “F-de-Córdoba and Torres (2012)”, but the latter did not show the useful technique well. Finally, I thought of asking you agai…

It should be something along the lines of tau_parameters = 0.1:0.3:0.8; temp_mat=NaN(size(oo_.steady_state,1),length(tau_parameters)); for i=1:length(tau_parameters) set_param_value('varpi',tau_parameters(i)); [oo_.steady_state,M_.params,info] = steady_(M_,options_,oo_); if ~info …

What exactly are you trying to do? What do you mean with “estimate the Laffer curve”?

In fact, the exact question is asked about looping a dynare.mod around a parameter. Is this possible? If yes, and if you allow it, can you give a simple example. I mentioned the Laffer curve as an example, how to show stationary states when tax rates vary from 0 to 1.

Have a look at [image] Loop over parameters Stochastic simulations 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 …

Very important, Thank You very much Professor.

Dear Professor @jpfeifer , Knowing that I have seen all the similar publications that have already been posted here on the forum, I still have two problems: 1- I don’t know how to export the steady state results in Excel format. 2- The second problem is the most important one. Indeed, I now need …

Use xlswrite. See (Not recommended) Write spreadsheet file - MATLAB xlswrite - MathWorks Deutschland What do you mean with [image] E.Ahmed: evolution of the variables around the parameter ?

Dear @jpfeifer After calculating the different values of Y at equilibrium, giving varpi=0.001, 0.002, 0.003, …, 1 using just dynare, I want to plot the (Y, varpi) but I don’t know how to do it. Thank you very much

You save both into a vector and then plot them using Matlab functions.

It is not clear. how I record the equilibrium matrix, then select the vectors to plot them. If you allow me to give a simple example, I really need it. I just looked at similar publications, but no case is appropriate for me. In case of need, you will find attached my code solt.mod (2.1 KB)

Dear @jpfeifer , Your answer is appropriate. I tested this code and the result was very good. Thank you very much for your help. Best Regards Ahmed
