Between 1999 and the onset of the economic crisis in 2008 real exchange rates in Greece, Ireland, Italy, Portugal and Spain appreciated relative to the rest of the euro area. This divergence in competitiveness was reflected in the emergence of current account imbalances. Given that exchange rate...

This paper analyzes the monetary-fiscal interaction if the central bank conducts quantitative easing. Although asset purchases have similar effects on the real economy under monetary and fiscal dominance, wealth effects yield a qualitatively different response on the rate of inflation. Our...

The recent crisis in the United States has often been associated with substantial amounts of policy uncertainty. In this paper we ask how uncertainty about fiscal policy affects the impact of fiscal policy changes on the economy when the government tries to counteract a deep recession. The...

In this article, we present a model that can account for the changes in the Germancurrent account balance since the 2000s. Our results suggest that an array of struc-tural tax and labor market reforms (Agenda 2010), population aging and pensionreforms led to an increase in the household savings...

We simulate the fiscal stimulus packages set up by the German government to allevi-ate the costs of the COVID-19 pandemic in a dynamic New Keynesian multi-sectorgeneral equilibrium model. We find that, cumulated over 2020-2022, output lossesrelative to steady state can be reduced by more than 4...

We analyze the long-run growth effects of automation in the canonical overlapping generations framework. While automation implies constant returns to capital within this model class (even in the absence of technological progress), we show that it does not have the potential to lead to positive...

Between 1999 and the onset of the economic crisis in 2008 real exchange rates in Greece, Ireland, Italy, Portugal and Spain appreciated relative to the rest of the euro area. This divergence in competitiveness was reflected in the emergence of current account imbalances. Given that exchange rate...

I calculate unemployment multipliers of fiscal consolidation policies in a standard, closed-economy New Keynesian framework with search and matching frictions, and, as an innovation, in the presence of sectoral heterogeneity. Family and non-family firms behave differently in the labor market and...

What happens when fiscal and/or monetary policy changes systematically? We construct a DSGE model in which agents have to estimate fiscal and monetary policy rules and assess how uncertainty surrounding the conduct of policymakers influences transition paths after policy changes. We find that...
