A fractional multi-states model for insurance

A common approach for pricing insurance contracts consists to represent the insured's health status by a Markov chain. This article extends this framework by observing this chain on a random scale of time, defined as the inverse of an α-stable process. This stochastic clock induces sub-exponential waiting times spent in each state. We first review and extend the properties of this time-change to a conditional filtration at time t > 0. Next we evaluate a general type of insurance contract from inception to expiry.
