Modelling stochastic bivariate mortality [PDF]

SSRN Electronic Journal, 2006
Stochastic mortality, i.e. modelling death arrival via a jump process with stochastic intensity, is gaining increasing reputation as a way to represent mortality risk.

Extensions on the Hatzopoulos–Sagianou Multiple-Components Stochastic Mortality Model

Risks, 2022
In this paper, we present extensions of the Hatzopoulos–Sagianou (2020) (HS) multiple-component stochastic mortality model. Our aim is to thoroughly evaluate and stress test the HS model by deploying various link functions, using generalised linear ...

Nonlinear Modeling of Mortality Data and Its Implications for Longevity Bond Pricing

Risks, 2023
Human mortality has been improving faster than expected over the past few decades. This unprecedented improvement has caused significant financial stress to pension plan sponsors and annuity providers. The widely recognized Lee–Carter model often assumes

Subnational Mortality Modelling: A Bayesian Hierarchical Model with Common Factors

Risks, 2021
We propose a new model in a Bayesian hierarchical framework to project mortality at both national and subnational levels based on sparse or missing data.

A Bibliometric Analysis of Research on Stochastic Mortality Modelling and Forecasting

Risks, 2022
Mortality improvements and life expectancies have been increasing in recent decades, leading to growing interest in understanding mortality risk and longevity risk. Studies of mortality forecasting are of interest among actuaries and demographers because

Bayesian Mixture Modelling for Mortality Projection

Risks, 2021
Although a large number of mortality projection models have been proposed in the literature, relatively little attention has been paid to a formal assessment of the effect of model uncertainty.

Robust Non-Parametric Mortality and Fertility Modelling and Forecasting: Gaussian Process Regression Approaches

Forecasting, 2021
A rapid decline in mortality and fertility has become major issues in many developed countries over the past few decades. An accurate model for forecasting demographic movements is important for decision making in social welfare policies and resource ...

Modelling USA Age-Cohort Mortality: A Comparison of Multi-Factor Affine Mortality Models

Risks, 2022
Affine mortality models are well suited for theoretical and practical application in pricing and risk management of mortality risk. They produce consistent, closed-form stochastic survival curves allowing for the efficient valuation of mortality-linked ...
