Investment fell sharply in the euro area after the financial crisis and has not yet returned to pre-crisis levels in many core economies. Focusing on the four largest euro-area countries, this paper investigates the role of uncertainty for investment dynamics. By doing so, we compare five...

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,...

We discuss how cross-country unemployment insurance can be used to improve international risk sharing. We use a two-country business cycle model with incomplete financial markets and frictional labor markets where the unemployment insurance scheme operates across both countries. Cross-country...

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'...

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...

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 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...

From an economic perspective, imposing a credible one-off net wealth levy in crisis times as a tool to ward off a national emergency appears to be advantageous as, in an ideal world, this would not distort market players' allocation decisions. However, in practice, charging such a levy may give...

By simulating various (labour market) integration scenarios with the aid of a New Keynesian DSGE model, this paper explores the potential economic consequences and transmission mechanisms resulting from the recent refugee migration to Germany. We find that the long-run costs and benefits for...
