Journal ArticleDOI
On a dual model with a dividend threshold
TL;DR: In this paper, the dual of the compound Poisson model under a threshold dividend strategy is considered and a set of two integro-differential equations satisfied by the expected total discounted dividends until ruin is derived.
Journal ArticleDOI
On the joint distribution of surplus before and after ruin under a Markovian regime switching model
TL;DR: In this article, the authors considered a Markovian regime switching insurance risk model and derived closed form solutions for the joint distribution of surplus before and after ruin when the initial surplus is zero or when the claim size distributions are phase-type distributed.
Journal ArticleDOI
Valuing variable annuity guarantees with the multivariate Esscher transform
TL;DR: In this article, a multivariate regime-switching model for modeling returns on various assets at the same time is proposed, and a risk-neutral probability measure for use with the model under consideration is identified.
Journal ArticleDOI
Canonical Valuation of Mortality-Linked Securities
TL;DR: The authors developed a framework for pricing mortality-linked securities on the basis of canonical valuation, which is largely nonparametric, helping us avoid parameter and model risk, which may be significant in other pricing methods.
Journal ArticleDOI
Pricing and Hedging Variable Annuity Guarantees with Multiasset Stochastic Investment Models
TL;DR: In this paper, a multivariate framework for pricing and hedging variable annuity guarantees is proposed, which can then be used for pricing purposes, and the potential hedging error can be quantified by stochastic simulations.
