The Robustness of Identified VAR Conclusions about Money

Abstract: This paper presents a n e w w a y to assess robustness of claims from identied VAR work. All possible identications are checked for the one that is worst for the claim, subject to t he restriction that the VAR produce reasonable impulse responses to shocks. The statistic on which t he claim is based need not b e i d e ntied; thus, one can a ssess claims in large m odels using minimal restrictions. The technique reveals only weak support for the claim that monetary policy shocks contribute a small portion of t … Show more

“…As regards the identification of macroeconomic shocks in step 4, we apply sign restrictions on short‐run impulse response functions (Faust , Canova and De Nicoló , Peersman , Uhlig ) and contemporaneous zero restrictions. The identification scheme is implemented in two steps.…”

“…We aim at estimating an aggregate supply shock, an aggregate real demand shock and a monetary policy shock. This is achieved by applying an identification scheme proposed recently by Faust (1998) and Uhlig (2005) for monetary policy shocks and extended to other macroeconomic shocks by Canova and De Nicoló (2003), Peersman (2005) and Peersman and Straub (2006). This identification scheme consists of imposing short‐run sign restrictions on impulse responses.…”

“…() (CFGZ henceforth) employ a VAR that contains endogenous variables similar to those in VAR‐CEE, but most importantly, it focuses on distinguishing financial uncertainty and financial condition shocks. Shocks are identified by the penalty function approach (PFA) initially proposed by Faust () and Uhlig (). Briefly stated, the PFA selects a structural VAR model by maximizing a criterion function subject to inequality constraints.…”
