I estimated my DSGE model with measurement errors calibrated. In “shocks block” I only included measurement errors, variance of another shocks (structural) are estimated by especificating priors distributions in estimated_params block.
My question are:

Will results of estimation (posteriors of parameters and shocks decomposition) change when I include structural shocks in “shocks block”?

I want to compute variance of variables evaluated after estimation, so my question is what happens when I don’t specify variance of structural shocks in “shock block”? Does dynare assume some especifical value for these, like 1, for example?
