Austerity measures are frequently enacted when the sustainability of public finances is in doubt. Such doubts are reflected in high sovereign yield spreads and put further strain on government finances. Is austerity successful in restoring market confidence, bringing about a reduction in yield...

This paper analyzes the effects of short-time work (i.e., government subsidized working time reductions) on unemployment and output fluctuations. The central question is whether short-time work saves jobs in recessions. In our baseline scenario the rule based component of short-time work (i.e.,...

In this paper, we use the estimated three-region DSGE model GEAR, which pictures Germany, the Euro Area and the Rest of the world and which is used by the Deutsche Bundesbank for policy analysis, to analyze how discretionary fiscal policy in Germany and the rest of EMU affected GDP growth and...

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...

The interaction between monetary and fiscal policy and the associated uncertainty about this interaction have been put on center stage by the recent financial crisis and the associated recession. In our model agents learn about both fiscal and monetary policy rules via the Kalman Filter. In...

Using VAR analysis on US data, we show that unanticipated fiscal expansions boost private consumption and business formation. Models with an extensive investment margin, i.e. endogenous firm and product entry, have difficulties explaining these two phenomena simultaneously. Considering different...

Which are the new frontiers in central banking? Which things have changed in the aftermath of the financial, economic and sovereign debt crisis? These are questions raised frequently by central bankers, academics and interested observers alike. There are quite a few areas to cover in answering...

In this study, we examine how the interaction between monetary policy and macroeconomic conditions affects inflation uncertainty in the long-term. The unobservable inflation uncertainty is quantified by means of the slowly evolving unconditional variance component of inflation in the framework...

In recent years, the number of theoretical models on sovereign default exploded. I take a step back and investigate how good our current theoretical understanding of real world sovereign debt crisis really is. This is done by deriving implications that are hard wired into our models and...
