Does fiscal policy have large and qualitatively different effects on the economy when the nominal interest rate is zero? An emerging consensus in the New Keynesian literature is that the answer is yes. New evidence provided here suggests that the answer is often no. For a broad range of...

This paper investigates the relevance of the No-Ponzi game condition for public debt (i.e. the public debt growth rate has to be lower than the real interest rate, a necessary assumption for Ricardian equivalence) and of the transversality condition for the GDP growth rate (i.e. the GDP growth...

We estimate indicators of aggregate demand and supply conditions based on a structural factor model using a large number of inflation and real activity measures for the United States. We identify demand and supply factors by imposing theoretically motivated sign restrictions on factor loadings....

This paper aims an empirical investigation of uncertainty in the Euro Zone as well as the US. For this purpose I conduct a factor analysis of uncertainty measures starting in 2001 until the end of 2011. I use survey-based data provided by the ECB and the Federal Reserve Bank of Philadelphia as...

Recent research has found that the dynamic properties of the New Keynesian model can be very different when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity, and the size of the government purchase output multiplier can be...

In this paper, we study maximizing long-run economic growth trade-off in monetary and fiscal policies in an endogenous growth model with transaction costs. We show that both monetary and fiscal policies are subject to threshold effects, a result that gives account of a number of recent empirical...

Distributional consequences typically receive limited attention in economic models that analyze the effects of monetary and financial sector policies. These consequences deserve more attention since financial markets are incomplete, imperfect, and economic agents' access to them is often...

Die Inflationsrate im Euroraum liegt seit knapp einem Jahr unterhalb der von der Europäischen Zentralbank angestrebten Zielmarke und wird voraussichtlich auch in der kommenden Zeit auf einem sehr niedrigen Niveau verharren. Zum einen steht eine solch geringe Inflation nicht im Einklang mit der...

Inflation in the euro area has been below the European Central Bank's target for almost a year now and it is also expected to remain at a very low level in the near future. On the one hand, such a low level of inflation is not in line with the ECB's objective. On the other hand, there is the...

The European sovereign debt crisis represents an interesting opportunity to investigate the reaction of the European Central Bank as a crisis fighting institution and the importance of central bank personalities in policy execution. Accordingly, this paper aims at investigating to what extent...
