Keynes’ original intention in introducing the concept of a liquidity trap was to explain the reason why persistent large amounts of unutilized resources were generated during the Great Depression. This paper shows that this type of phenomenon cannot be explained in the framework of a...

We construct an endogenous growth model with new Keynesian-type sticky prices and wages. In this model, monetary policy affects long-run output growth. We characterize the optimal operational monetary policy rule in this economy. We find that even though stabilization of output growth increases...

Die Niedrigzinspolitik der EZB hat in vielen Ländern des Euroraums zu einem starken Anstieg der Wohnimmobilienpreise beigetragen. In einigen Mitgliedstaaten mündeten diese Übertreibungen am Wohnimmobilienmarkt bereits in Finanz- und Schuldenkrisen. Der Harmonisierte Verbraucherpreisindex...

Models dealing with monetary policy are generally based on microfoundations that characterize the behaviour of representative agents (households and firms). To explain the representative consumer behaviour, it is generally assumed a utility function in which the intertemporal elasticity of...

The standard new Keynesian monetary policy problem is, in its original presentation, a linear model. As a result, only three possibilities are admissible in terms of long term dynamics: the equilibrium may be a stable node, an unstable node or a saddle point. Fixed point stability (a stable...

We use disaggregated data on the components of private fixed investment (PFI) to estimate industry-level responses of real investment and capital prices to unanticipated monetary policy. The response functions derive from a restricted large-scale VAR estimated over 1959-2007. Our results point...

In the paper we propose an assessment of the role of financial innovation in shaping US macroeconomic dynamics. We extend an existing model by Christiano, Eichenbaum and Evans which studied the transmission of monetary policy impulses to business and corporate sector financing variables just...

Das Urteil des Bundesverfassungsgerichts zur EZB-Politik vom 5. Mai 2020 wird der strategischen Problematik der Geldpolitik nicht gerecht. Insbesondere die künstliche Unterscheidung zwischen erlaubter "Geldpolitik" und nicht erlaubter "Wirtschaftspolitik" ist unangemessen. Die daraus...

This paper explores three areas in which the experience of the Great Depression might be relevant today: monetary policy, fiscal policy and the systemic stability of the banking system. We confirm the consensus on monetary policy: deflation must be avoided. With regard to fiscal policy, the...

The slight slowdown of consumer price infl ation in Germany in November does not yet constitute the beginning of lower infl ation rates. Even though energy prices are dragging infl ation, producer prices have drastically increased in the past year. Our estimates indicate that infl ation rates...
