Past empirical research on monetary policy in open economies has found evidence of the ‘delayed overshooting puzzle’ and the ‘forward discount puzzle’. We revisit the effects of monetary policy on exchange rates by applying Uhlig's [Uhlig, H., 2005a. What are the effects of monetary policy...

This paper analyzes optimal foreign aid policy in a neoclassical growth framework with a conflict of interest between the donor and the recipient government. Aid conditionality is modeled as a limited enforceable dynamic contract. We define the contract to be self-enforcing if, at any point in...

We show that the empirical distribution of the roots of the vector auto-regression of order n fitted to T observations of a general stationary or non-stationary process, converges to the uniform distribution over the unit circle on the complex plane, when both T and n tend to infinity so that...

This paper compares monetary policy in the US and EMU during the last decade, employing an estimated hybrid New Keynesian cash-in-advance model, driven by five shocks. It appears that the difference between the two monetary policies between 1998 and 2006 is due to both surprises in productivity...

When a central bank introduces a central bank digital currency, it may lead to an erosion of deposits as the stable funding base of banks and result in challenges regarding the asset side of the central bank. We study the resulting economy and tradeoffs in a stylized nominal version of the...

The aim of this paper is to construct theoretical models which help to shed light on the recent criticisms of volatile investment flows. We do not make any empirical attempt to establish the exisitence or gauge the importance of the adverse affects of flows in recent exchange rate crises....

Diese Dissertation besteht aus drei Aufsätzen, welche die Effekte von Geld- und Fiskalpolitiken für die Makroökonomie untersuchen. Der erste Aufsatz analysiert, wie das Verhalten der Inflation nach z.B. geldpolitischen Veränderungen erklärt werden kann. Mankiw und Reis (2002) propagieren...

Die Dissertation entwickelt und untersucht Methoden für die Analyse dynamischer Mehrgleichungsmodelle (VAR Modelle). Zuerst wird ein allgemeines Konzept für die Einbindung statistischer Prozeduren in eine menügesteuerte Software entwickelt. Die resultierende Java--Bibliothek besteht aus...
