Structural VAR models are frequently identified using sign restrictions on contemporaneous impulse responses. We develop a methodology that can handle a set of prior distributions that is much larger than the one currently allowed for by traditional methods. We then develop an importance sampler...

We propose a new instrument to identify uncertainty shocks in a SVAR model with external instruments. The instrument is constructed by exploiting variations in the price of gold around events that capture periods of changes in uncertainty. The variations in the price of gold around the events...

Before the 2007 crisis, the trade-off between output and inflation played a leading role in the discussion of monetary policy. Instead, issues relating to financial stability played a less pronounced role in shaping the stance of monetary policy and were limited to asset price dynamics. This...

The European Central Bank has engaged in a wide range of nonstandard monetary policy measures since 2007. Each new tool was accompanied by an intense public debate on its effectiveness. This study evaluates the average effect of these measures on the macro-economy. The estimates show that...

Die Europäische Zentralbank hat seit 2007 zahlreiche unkonventionelle geldpolitische Maßnahmen umgesetzt. Jedes neue Instrument wurde von einer heftigen öffentlichen Debatte über seine Wirksamkeit begleitet. Diese Studie evaluiert die makroökonomischen Effekte dieser Maßnahmen. Die...

We propose a new instrument to identify the impact of uncertainty shocks in a SVAR model with external instruments. We construct the instrument for uncertainty shocks by exploiting variations in the price of gold around selected events. The events capture periods of changes in uncertainty...

This paper uses a structural VAR model to study the effect of monetary policy on the delinquency rate of business loans and consumer credit. The VAR is identified using at the same time several external instruments, which cover different approaches from the literature. Delinquency rates, defined...

This paper proposes a Bayesian approach to assess if the data support candidate set-identifying restrictions for Vector Autoregressive models. The researcher is uncertain about the validity of some sign restrictions that she is contemplating to use. She therefore expresses her uncertainty with a...

This Roundup discusses the literature on the effects of uncertainty on economic activity. Uncertainty will be generally referred to as the agents' inability to form clear expectations about the future path of relevant economic variables. After motivating the analysis from a policy perspective,...

We study the macroeconomic effects of unconventional monetary policy in the euro area using structural vector autoregressions, identified with external instruments. The instruments are based on the common unexpected variation in euro area sovereign yields for different maturities on policy...
