We propose an observation-driven time-varying SVAR model where, in agreement with the Lucas Critique, structural shocks drive both the evolution of the macro variables and the dynamics of the VAR parameters. Contrary to existing approaches where parameters follow a stochastic process with random and exogenous shocks, our observation-driven specification allows the evolution of the parameters to be driven by realized past structural shocks, thus opening the possibility to gauge the impact of…

Hodges–Lehmann Detection of Structural Shocks – An Analysis of Macroeconomic Dynamics in the Euro Area
Structural shocks in multivariate dynamic systems are hidden and often identified with reference to a priori economic reasoning. Based on a non‐Gaussian framework of independent shocks, this work

Identification of Singular and Noisy Structural VAR Models: The Collapsing-ICA Approach
When the number of variables is larger than the number of structural shocks driving the economy,<br>the associated structural VAR system is said to be singular. We propose an identification method
Macroeconomic responses to an independent monetary policy shock: a (more) agnostic identification procedure
This study investigates the effects of a monetary policy shock on real output and prices, by means of a novel distribution-free nonrecursive identification scheme for structural vector
Predicting Time-Varying Parameters with Parameter-Driven and Observation-Driven Models
In an extended Monte Carlo study, evidence is presented that observation-driven models based on the score of the predictive likelihood function have similar predictive accuracy compared to their correctly specified parameter-driven counterparts.
Information-theoretic optimality of observation-driven time series models for continuous responses
We investigate information-theoretic optimality properties of the score function of the predictive likelihood as a device for updating a real-valued time-varying parameter in a univariate
Common faith or parting ways? A time varying parameters factor analysis of Euro-area inflation
We analyze the interaction among the common and country specific components for the inflation rates in twelve euro area countries through a factor model with time varying parameters. The variation of
Structural Vector Autoregressions With Nonnormal Residuals
In structural vector autoregressive (SVAR) modeling, sometimes the identifying restrictions are insufficient for a unique specification of all shocks. In this paper it is pointed out that specific
