We first discuss some mathematical tools used to compute the intensity of a single jump process, in its canonical filtration. In the second part, we try to clarify the meaning of default and the links between the default time, the asset?s filtration, and the intensity of the default time. We...

Previous work on multifactor term structure models has proposed that the short rate process is a function of some unobserved diffusion process. We consider a model in which the short rate process is a function of a Markov chain which represents the 'state of the world'. This enables us to obtain...

Filtering and parameter estimation techniques from Hidden Markov Models are applied to a discrete time asset allocation problem. For the commonly used mean-variance utility explicit optimal strategies are obtained

This paper is intended to elaborate regime switching and optimal investment timing in a real option framework. The paper differs from the existing literature in a significant way. In this paper we first consider an irreversible investment timing decision by adding a hidden Markov process to...

A data set of the holiday destination choices of German tourists is segmented using phase in the life cycle; second, holiday motivation and holiday activities and third, the region of residency. For each segment demand is estimated using data on environmental and economic characteristics of...
