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...

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 study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence give rise to persistent liquidity trap episodes. There is no straightforward recipe for enhancing welfare in this economy. Raising the inflation target or appointing an...

We study the incidence and severity of lower-bound episodes and the efficacy of three types of state-dependent policies - forward guidance about the future path of interest rates, large-scale asset purchases and spending-based fiscal stimulus - in ameliorating the adverse consequences stemming...

We use scenario analysis to assess the macroeconomic effects of carbon transition policies aimed at mitigating climate change. To this end, we employ a version of the ECB's New Area-Wide Model (NAWM) augmented with a framework of disaggregated energy production and use, which distinguishes...

What are the macroeconomic consequences of a government that is limited in its willingness or ability to raise primary surpluses, and a central bank that accommodates its interest-rate policy to the fiscal conditions? I address this question in a dynamic stochastic sticky-price model with...

This paper studies optimal government spending and monetary policy when the nominal interest rate is subject to the zero lower bound constraint in a stochastic New Keynesian economy. I find that the government chooses to increase its spending when at the zero lower bound by a substantially...

We quantify the size of fiscal multipliers under financial fragmentation risk and demonstrate how non-standard monetary policy can support the macroeconomic transmission of fiscal interventions. We employ a DSGE model with financial frictions whereby the interplay of corporate, banks and...

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...

In most euro area countries, the monetary/fiscal policy mix is responsible for the changing history of debt and inflation facts. Using a Dynamic Stochastic General Equilibrium model with Markov-switching policy rules, we identify three distinct monetary/fiscal regimes in France and Italy: a...
