We examine the sources of macroeconomic economic fluctuations by estimating a variety of medium-scale DSGE models within a unified framework that incorporates regime switching both in shock variances and in the inflation target. Our general framework includes a number of different model features...

Strengthening potential output is high on the agenda for economic policy in the European Union. While there is widespread agreement that structural policies have a positive impact on long-term growth, there is a controversial discussion whether coordination of macroeconomic policies can...

We propose a method for indentifying discretionary fiscal policy with real time data. The starting point is the observation that automatic stabilizers should depend on true GDP, while discretionary fiscal policy depends on the information that policy makers have in real time. We approximate the...

Weltweit werden etwa 3 Billionen US-Dollar staatlicher Hilfen ausgegeben, um den Absturz der Weltwirtschaft abzubremsen. Dieser Nachfrageschub von 4,7 Prozent des Welteinkommens hat zuallererst die Aufgabe, die Spirale gestrichener Investitionspläne, reduzierter Produktion, gesunkener...

We quantify the fiscal multipliers in response to the American Recovery and Reinvestment Act (ARRA) of 2009. We extend the benchmark Smets-Wouters (Smets and Wouters, 2007) New Keynesian model, allowing for credit-constrained households, the zero lower bound, government capital and distortionary...

This paper is concerned with the apparent change in the U.S. oil price-macroeconomy relationship. It is investigated to what extent this change can be accounted for by the large oil price surges witnessed in the 1970s. The innovative approach of rolling impulse responses is applied and both the...

This paper analyzes the effectiveness of the tax and transfer systems in the European Union and the US to act as an automatic stabilizer in the current economic crisis. We find that automatic stabilizers absorb 38 per cent of a proportional income shock in the EU, compared to 32 per cent in the...

There is a wide consensus that the existence of structural rigidities in the Eurozone reduces the effectiveness of the ECB's monetary policies. In order to test this ?ECB-handicap? hypothesis, we perform a meta-analysis of the effects of monetary policies in the US and the Eurozone countries....

The existing empirical literature on Taylor-type interest rate rules has failed to achieve a robust consensus. Indeed, the relatively common finding that the Taylor principle does not hold has fueled a degree of controversy in the field. We attribute these mixed estimation results to a raft of...
