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...

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,...

Budget-neutral tax wedge reductions rank high in the policy agenda of several EMU member states. Using a New Keynesian DSGE model of a monetary union with a complex labour market structure and a comprehensive public sector, we evaluate the macroeconomic and welfare effects of reducing the firms'...

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 a real business cycle model with labor market frictions, we find that a more progressive tax schedule reduces structural unemployment as it fosters long-run incentives for job creation. Because there exists an optimal level of unemployment in a matching environment ("Hosios condition), tax...

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...

This paper studies the market microstructure of pre-industrial Europe. In particular we investigate the institution of the broker in markets and fairs, and develop a unique data set of approximately 1100 sets of brokerage rules in 42 merchant towns in Central and Western Europe from the late...

Repo markets offering central counterparty (CCP) clearing and anonymized trading were remarkably resilient during the recent crises. We use the full transaction level dataset on all repo trades on Eurex Repo, including identifiers for market participants, to provide a detailed description of the...

We study a game in which two firms compete in quality to serve a market consisting of consumers with different initial consideration sets. If both firms invest below a certain threshold, they only compete for those consumers already aware of their existence. Above this threshold, a firm is...
