Dynamic Stochastic General Equilibrium (DSGE) models are typically singular. Thus, for likelihood-based structural parameters estimation, one needs to select the variables to use or add artificial disturbances to remove the singularity. Alternatively, one could use a composite likelihood of non -singular models. I compare various estimation approaches, provide conditions for the additional shocks to remove singularity, study shock identification and parameter estimates distortions; and reexamine the sources of macroeconomic fluctuations. Adding shocks may be counterproductive. A composite likelihood approach minimizes the distortions. The importance of monetary shocks for inflation is likely to be underestimated; TFP shocks are driving output fluctuations.
