We investigate identifiability issues in DSGE models and their consequences for parameter estimation and model evaluation when the objective function measures the distance between estimated and model impulse responses. Observational equivalence, partial and weak identification problems are...

We employ a novel identification scheme to quantify the macroeconomic effects of monetary policy shocks in the United States. The identification of the shocks is achieved by exploiting the instabilities in the contemporaneous coefficients of the structural VAR (SVAR) and in the covariance matrix...
