The NAIRU is a key component of potential output and as such critically affects output gap estimates. In May 2014, the European Commission changed its specification of the NAIRU for several countries and lowered its NAIRU estimates - in the case of Spain from 26.6% to 20.7% for 2015. To test the...

The euro area crisis drags on. Austerity measures in the crisis countries are deepening an already severe recession and this is having knock-on effects on the entire currency area. Policymakers have largely ignored the central cause of the crisis - the persistent failure by member states to keep...

We apply meta regression analysis to a unique data set of 104 studies on multiplier effects with 1069 reported multipliers in order to derive stylized facts and to quantify the differing effectiveness of the composition of fiscal impulses, adjusted for the interference of study-design...

To address the on-going crisis in the euro area it is proposed to introduce a scheme of conditional, overt monetary financing of public investment (COMFOPI). The inadequate response of monetary and fiscal policy is shown to explain the weak performance of the euro area compared with other...

Using the bottom-up approach of Romer and Romer (2010), we construct a rich narrative dataset of net-revenue fiscal shocks for Germany by reconstructing and extending the tax shock series of Hayo and Uhl (2014) and coding a shock series for social security contributions, benefits and transfers....

We analyze whether there are negative (positive) long-term effects of austerity measures (stimulus measures) on potential output growth. Based on the approach of Blanchard and Leigh (2013) and Fatás and Summers (2016) and using a novel dataset of narratively identified fiscal policy shocks, we...

We analyze whether estimated multiplier effects are systematically higher if the economy suffers a downturn. For that purpose, we conduct a meta-regression analysis on a unique data set of 98 empirical studies with more than 1800 observations on multiplier effects and control for regime...

We show that fiscal multiplier estimations may be biased by movements in asset and credit markets, as they facilitate spurious correlations of changes in cyclically adjusted revenues and spending with GDP growth via wrong identifications and an omitted variable bias, thus overstating episodes of...

Since the fiscal expansion during the Great Recession 2008-2009 and the current European consolidation and austerity measures, the analysis of fiscal multiplier effects is back on the scientific agenda. The number of empirical studies is growing fast, tackling the issue with manifold model...
