I have a strong confusion (after checked the manual for dynare 4.6.4) with respect to the results given by Dynare with respect to the commands for the optimal policy function and I need yout help.
When I use only the planner_objective and ramsey_model command what results do I get and how are they displayed? it gives me somewhere the optimal values for variables or parameters?
When I insert evaluate_planner_objective I get numeric values by setting 1) the lagrange multipliers = 0, 2) the lagrange multipliers in steady state. What do those numerical results of the planner objective indicate? are they welfare losses? (with some welfare measure i can obtain in fact negative values) or are the values of the objective function maximized (with other objective function I obtain positive ones)
is it possible that they are equal in both the lagrange=0 and lagrange=SS cases (would it mean that my lagrange multiplier are 0 in steady state and so basically it is like I have an unconstrained maximization?)
Thank you all for any help
