Hamilton (2018) argues that one should never use the Hodrick-Prescott (HP) filter to detrend economic time series and proposes an alternative approach. This comment reconsiders Hamilton's case against the HP filter, emphasizing two simple points. First, in the empirical example Hamilton...

Policy makers need to separate between temporary demand-driven shocks and permanent shocks in order to design optimal aggregate demand policies. In this paper we study the case of a central bank that ignores the presence of hysteresis when identifying shocks. By assuming that all low-frequency...

This study examines whether and how important it is to adjust output gap frameworks during the COVID-19 pandemic and similar unprecedentedly large-scale episodes. Our proposed modelling framework comprises a Bayesian Structural Vector Autoregresion with an identification setup based on a...

Der Aufsatz untersucht einige populäre Methoden zur Messung des Output Gaps auf der Basis von aggregierten Daten für die Euro-Zone. Obwohl die Methoden einige wichtige gemeinsame Eigenschaften aufweisen, zeigen sie auch erhebliche Unterschiede; insbesondere ist die Korrelation zwischen...

The output gap is a key variable of business cycle analysis and policy. Obtaining reliable estimates for it, is very difficult, though. Most real-time estimates are frequently revised over time. The idea of this paper is to use various indicators, for example from business surveys, that (i) were...

The literature on business cycle synchronization in Europe frequently presumes an alleged ‘core‒periphery’ pattern without providing empirical verification of the underlying cyclical (dis)similarities or the supposed but unobservable ‘European business cycle(s)’. To provide a...

All types of recessions, on average, not just those associated with financial and political crises (as in Cerra and Saxena, AER 2008), lead to permanent output losses. These findings have far-reaching conceptual and policy implications. A new paradigm of the business cycle needs to account for...

The path of output prior to the financial and economic crisis turned out to be not sustainable and lower than previously estimated in some European crisis countries. Specifically, the output gaps have been underestimated (and inversely potential output overestimated) before the recent crisis. It...
