Simulation results after DSGE model estimation

Hi.

I estimate a DSGE model with estimation(…) command and after this command I use stoch_simul(…) command for simulation of the model and to get impulse response functions and conditional variance decomposition.

My question is that in this situation Dynare for simulation of the model employs posterior means of the parameters in simulation process??

I ask this question because I set posterior means in simulation of the model without estimation but the results of simulated moments such as standard deviations are not the same.

That depends on what you do in estimation. The behavior is documented in the manual.
