I would like to ask how, in Dynare, one can generate a similar figure that examines the regions where the coefficients of monetary policy lead to a unique solution or indeterminacy in the model, and if there are any examples of code for this purpose?
See
It seems that I need to be able to obtain a feasible result before I can proceed with the plotting of the determinacy region. Is that correct?
If your model still has a fundamental issue with the Blanchard-Kahn conditions, then plotting the determinacy region will not help.
