In the context of the present-value stock-price model, we propose a new rational parametric bubble specification that is able to generate periodically recurring and stochastically deflating trajectories. Our bubble model is empirically more plausible than its predecessor variants and has neatly...

The volatility of interest rates is relevant for many financial applications. Under realistic assumptions the term structure of interest rate differentials provides an important predictor of the term structure of interest rates. This paper derives the term structure of differentials in a...

Several theoretical models suggest that the mere announcement of entering a currency union in the future triggers instantaneous changes in exchange-rate volatility. First, this paper develops a Markov-switching framework by which, in fact, volatility regime-switching in foreign exchange rates...

Based on Lorenz comparisons of two random variables from the four-parameter generalized beta distribution of the first kind, Lorenz-order relationships among order statistics from different power-function samples with varying sizes are obtained.

Based on a theoretical monetary exchange-rate model in continuous time, this article establishes a sequential estimation framework which is capable of indicating central bank intervention in the run-up to a currency union. Using daily pre-European Monetary Union (pre-EMU) exchange-rate data for...

Motivated by repeated spikes and crashes during previous decades we investigate whether the heavily financialized market for crude oil has been driven by speculative bubbles. In our theoretical modeling we draw on the convenience yield approach in order to approximate the fundamental value of...

Die vorliegende Arbeit analysiert die Wechselkursdynamik eines glaubwürdig angekündigten, zeitlich fest anvisierten Übergangs von flexiblen zu festen Wechselkursen auf der Grundlage eines monetären Wechselkursmodells mit flexiblen Preisen. Verschiedene währungspolitische Ereignisse werden...
