A spatial mixed Poisson framework for combination of excess-of-loss and proportional reinsurance contracts [PDF]
In this paper a purely theoretical reinsurance model is presented, where the reinsurance contract is assumed to be simultaneously of an excess-of-loss and of a proportional type. The stochastic structure of the set of pairs (claim’s arrival time, claim’s

Error estimates for De Vylder type approximations in ruin theory
Due to its practical use, De Vylder's approximation of the ruin probability has been one of the most popular approximations in ruin theory and its application to insurance. Surprisingly, only heuristic and numerical evidence has supported it, to some extent.

Bayesian deconvolution of scanning electron microscopy images using point-spread function estimation and non-local regularization [PDF]
Microscopy is one of the most essential imaging techniques in life sciences. High-quality images are required in order to solve (potentially life-saving) biomedical research problems.

Calculating multivariate ruin probabilities via Gaver–Stehfest inversion technique [PDF]
Multivariate characteristics of risk processes are of high interest to academic actuaries. In such models, the probability of ruin is obtained not only by considering initial reserves u but also the severity of ruin y and the surplus before ruin x. This

On the accuracy of phase-type approximations of heavy-tailed risk models [PDF]
Numerical evaluation of ruin probabilities in the classical risk model is an important problem. If claim sizes are heavy-tailed, then such evaluations are challenging.

Extinction in a branching process: Why some of the fittest strategies cannot guarantee survival [PDF]
The fitness of a biological strategy is typically measured by its expected reproductive rate, the first moment of its offspring distribution. However, strategies with high expected rates can also have high probabilities of extinction. A similar situation

Analytical and numerical approach to corporate operational risk modelling [PDF]
Although The New Basel Accord gives the methodology for managing operational risk in financial institutions, corporate risk seems not to be recognized enough. In this Ph.D.

The win-first probability under interest force [PDF]
In a classical risk model under constant interest force, we study the probability that the surplus of an insurance company reaches an upper barrier before a lower barrier. We define this probability as win-first probability.
