In this paper we analyze the dynamics of zero-coupon bond options in a situation in which two open economies plan to enter a currency union in the future. More precisely, we make use of recent theoretical work on the continuous-time dynamics of interest-rate differentials between the economies...

We analyze the dynamics of zero-coupon bond options in a situation in which the currently floating exchange rate between two countries' currencies is announced to be fixed on a given future date. To this end, we combine two strands of research that have been treated as separate issues up to...

In this paper we develop a unifying Markov-switching GARCH model which enables us (1) to specify complex GARCH equations in two distinct Markov-regimes, and (2) to model GARCH equations of different functional forms across the two Markov-regimes. To give a simple example, our flexible...

Veränderungen der Rahmenbedingungen auf Finanzmärkten müssen von ökonomischen und ökonometrischen Modellen sinnvoll erfasst werden. Diese Dissertation beschäftigt sich mit der Zinsdynamik im Vorfeld einer Währungsunion. Auf diese Dynamik aufbauend werden Optionen auf Nullkuponanleihen...
