Risks, 2017 In this study we develop a multi-factor extension of the family of Lee-Carter stochastic mortality models. We build upon the time, period and cohort stochastic model structure to extend it to include exogenous observable demographic features that can be ...

Stability of positive equilibrium of a Nicholson blowflies model with stochastic perturbations
Electronic Journal of Qualitative Theory of Differential Equations, 2020 This paper is concerned with the stability problem of the positive equilibrium of a Nicholson's blowflies model with nonlinear density-dependent mortality rate subject to stochastic perturbations.

The Investigation of a Forward-Rate Mortality Framework
Risks, 2019 Stochastic mortality models have been developed for a range of applications from demographic projections to financial management. Financial risk based models built on methods used for interest rates and apply these to mortality rates.

Stochastic modeling of assets and liabilities with mortality risk [PDF]
Scandinavian Actuarial Journal, 2021 This paper describes a general approach for stochastic modeling of assets returns and liability cash-flows of a typical pensions insurer. On the asset side, we model the investment returns on equities and various classes of fixed-income instruments including short- and long-maturity fixed-rate bonds as well as index-linked and corporate bonds.

Ecology and Evolution, 2020 The consequences of bird mortality caused by collisions with wind turbines are increasingly receiving attention. So‐called acceptable mortality limits of populations, that is, those that assume that 1%–5% of additional mortality and the potential ...

A Bayesian Approach to Developing a Stochastic Mortality Model for China [PDF]
Journal of the Royal Statistical Society Series A: Statistics in Society, 2019 SummaryStochastic mortality models have a wide range of applications. They are particularly important for analysing Chinese mortality, which is subject to rapid and uncertain changes. However, owing to data-related problems, stochastic modelling of Chinese mortality has not been given adequate attention.
