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,...

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...

We employ a neoclassical growth model to assess the impact of financial liberalization in a developing country on capital owners` and workers` consumption and welfare. We find in a baseline calibration for an average non-OECD country that capitalists suffer a 42 percent reduction in permanent...

We show in a dynamic stochastic general equilibrium framework that the introduction of a common currency by a group of countries with only partially integrated goods markets, incomplete financial markets and no labor migration across member states, significantly increases volatility of...

This paper studies Ramsey-optimal monetary and fiscal policy in a New Keynesian 2-country open economy framework, which is used to assess how far fiscal policy can substitute for the role of nominal exchange rates within a monetary union. Giving up exchange rate flexibility leads to welfare...

Within the economic profession, it is a widely held view that the fiscal criteria of the Maastricht treaty are arbitrary numbers without economic foundation. Much of this criticism seems to overlook an important aspect - the strategic dimension of the criteria. This paper focuses on one...

Are the characteristics of the exchange rate regime relevant for the degree of fiscal discipline? What are the conclusions for fiscal behavior in Europe after the transition to EMU? These are the central questions that are analyzed in this paper from a theoretical point of view. After a general...

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...
