In this paper we discuss general identification results for Structural Vector Autoregressions (SVARs) with external instruments, considering the case in which r valid instruments are used to identify g ≥ 1 structural shocks, where r ≥ g. We endow the SVAR with an auxiliary statistical model...

High-frequency (HF) surprises of relevant asset prices around central bank meetings are extensively employed in the literature to identify the effects of conventional/unconventional monetary policy. This identification strategy assumes that these surprises reflect either a single unconventional...

To unveil the strategic interaction between the government and the labour union in a unionised economy, a policy-game model is estimated by cointegrated Vector Autoregressive system using Italian quarterly data (1960-2009) on government budget surplus (fiscal efforts), hours not worked...

High-frequency (HF) monetary surprises around central bank meetings are extensively employed to jointly identify unconventional monetary policy shocks along with an `information shock'. In this paper we show that HF surprises in the Euro Area after 2008 best reflect the impact of three shocks,...

High-frequency (HF) surprises of relevant asset prices around central bank meetings are extensively employed in the literature to identify the effects of conventional/unconventional monetary policy. This identification strategy assumes that these surprises reflect either a single unconventional...

When in proxy-SVARs the covariance matrix of VAR disturbances is subject to exogenous, permanent, nonrecurring breaks that generate target impulse response functions (IRFs) that change across volatility regimes, even strong, exogenous external instruments can result in inconsistent estimates of...
