In a New Keynesian DSGE model with non-Ricardian consumers, we show that automatic stabilization according to a countercyclical spending rule following the idea of the debt brake is well suited both to steer the economy and in terms of welfare. In particular, the adjustment account set up to...

This paper analyzes Germany's fiscal policy position. Half of GDP passes through the hands of government, a high debt to GDP ratio limits the maneuvering, and the revenue sharing mechanism prevents a competitive federalism. Most importantly for the future, the federal finance minister has to...

In a dynamic model of fiscal policy, social polarization provokes a deficit bias. Policy advisors have recently proposed that governments running a deficit should be forced to generate additional tax revenue. We show that this deficit taxation reduces the deficit bias as it internalizes the...

In this paper, we assess the impact of major German structural reforms from 1999 to 2008 on key macroeconomic variables. By many, these reforms, especially the Hartz reforms on the labor market, are considered to be the root of observed imbalances in the Euro Area. Our simulations within a...

Using an estimated large-scale New-Keynesian model, we assess welfare and business cycle consequences of a fiscal union within EMU. We differentiate between three different scenarios: public revenue equalisation, tax harmonisation and a centralised fiscal authority. Relative to the status quo,...

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...

In this paper,we assess the impact ofmajor German structural reforms from1999 to 2008 on key macroeconomic variables within a two-country monetary union DSGE model. Bymany, these reforms, especially the Hartz reforms on the labormarket, are considered to be the root of thereafter observed...

We present the estimated large-scale three-region DSGE model GEAR picturing Germany, the Euro Area and the Rest of the world. Compared to existing models of this type, GEAR incorporates a comprehensive fiscal block, involuntary unemployment and a complex international structure. We use the model...
