This paper considers investment problems in real options with non-homogeneous two-factor uncertainty. We derive some analytical properties of the resulting optimal stopping problem and present a finite difference algorithm to approximate the firm’s value function and optimal exercise boundary....

The core of risk aggregation in the Solvency II Standard Formula is the so-called square root formula. We argue that it … should be seen as a means for the aggregation of different risks to an overall risk rather than being associated with … variance-covariance based risk analysis. Considering the Solvency II Standard Formula from the viewpoint of linear geometry, we …
