We investigate whether a government should lead an activist policy in a rigorous utility maximizing framework under rational expectations. The economy is a monetary one with preset wages, and is subject to both demand and supply shocks. It is assumed that the government can never act on the...

In structural vector autoregressive analysis identifying the shocks of interest via heteroskedasticity has become a standard tool. Unfortunately, the approaches currently used for modelling heteroskedasticity all have drawbacks. For instance, assuming known dates for variance changes is often...

Negative interest rates remain a controversial policy for central banks. We study a novel signalling channel and ask under what conditions negative rates should exist in an optimal policymaker’s toolkit. We prove two necessary conditions for the optimality of negative rates: a time-consistent...

We develop a structural vector autoregressive framework that combines external instruments and heteroskedasticity for identification of monetary policy shocks. We show that exploiting both types of information sharpens structural inference, allows testing the relevance and exogeneity condition...

Conditional on a contractionary monetary policy shock, the labor share of value added is expected to decrease in the basic New Keynesian model. By providing firm-level evidence, we are first to validate this proposition. Using local projections and high dimensional fixed effects, we show that a...

We propose a behavioral heterogeneous agent New Keynesian model in which monetary policy is amplified through indirect general equilibrium effects, fiscal multipliers can be larger than one and which delivers empirically-realistic intertemporal marginal propensities to consume. Simultaneously,...

We reexamine whether pre-Volcker U.S. fiscal policy was active or passive. To do so, we estimate a DSGE model with monetary and fiscal policy interactions employing a sequential Monte Carlo algorithm (SMC) for posterior evaluation. Unlike existing studies, we do not have to treat each policy...

We disentangle the effects of monetary policy announcements on real economic variables into an interest rate shock component and a central bank information shock component. We identify both components using changes in interest rate futures and in exchange rates around monetary policy...

We analyze the positive and normative effects of a progressive tax on wages in a nonlinear New Keynesian DSGE model in the presence of demand and technology shocks. The non-linearity allows us to disentangle the effects of the progressive tax on the volatility and the level of macroeconomic...

We examine whether monetary transmission during the financial and sovereign debt crisis was dominated by the cost channel or by the demand-side channel effect. We use two approaches to track down the potential passthrough of changes in the monetary policy rate to those in consumer prices. First,...
