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...

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...

When is it optimal for a government to default on its legal repayment obligations? We answer this question for a small open economy with domestic production risk in which contracting frictions make it optimal for the government to finance itself by issuing non-contingent debt. We show that...

Recent macro developments in the euro area have highlighted the interactions between fiscal policy, sovereign debt, and financial fragility. We take a structural macroeconomic model with frictions in the financial intermediation process, in line with recent research, but introduce asset choice...

Cogan et al. (2009, 2010) claim that the stimulus package passed by the United States Congress in February 2009 had a multiplier far below one. However, the stimulus ́multiplier strongly depends on the assumed monetary policy response. Based on official statements from the Fed chairman, the...

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,...

Yes, indeed; at least for macroeconomic policy interaction. We examine a Neo-Classical economy and provide the conditions for policy arrangements to successfully stabilize the economy when agents have either rational or adaptive expectations. For a contemporaneous-data monetary policy rule, the...

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...
