We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence can give rise to persistent liquidity trap episodes. Unlike in the case of fundamental-driven liquidity traps, there is no straightforward recipe for mitigating the welfare costs...

We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model, in which capacity constraints at the plant level generate convex supply curves at the industry level. The industry's capacity utilization rate is a sufficient statistic for the...

Quantifying the effects of trade policy in the age of "global value chains" (GVCs) requires an enhanced analytical framework that takes the observed international input-output relations in due account. However, existing quantitative general equilibrium models generally assume that industry-level...

This paper analyzes the impact of monetary policy on public debt sustainability through the lens of a general equilibrium model with fiscal limits. We find that the mere possibility of a binding ZLB may have detrimental effects on debt sustainability, as a kink in the Laffer curve induces a...

Quantitative analysis of a New Keynesian model with the Bernanke-Gertler accelerator and risk shocks shows that violations of Tinbergen's Rule and strategic interaction between policymaking authorities undermine significantly the effectiveness of monetary and financial policies. Separate...

This paper uses two established DSGE models (QUEST III and Smets-Wouters) to assess the impact of fiscal spending cuts on output and, in particular, also on inflation in the euro area under alternative settings for monetary policy. We compare four different settings of constrained monetary...

How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...
