This study sets out a framework to evaluate the goodness of fit of stochastic mortality models and applies it to six different models estimated using English & Welsh male mortality data. The methodology exploits the structure of each model to obtain various residual series that are predicted to...

This study sets out a backtesting framework applicable to the multi-period-ahead forecasts from stochastic mortality models and uses it to evaluate the forecasting performance of six different stochastic mortality models applied to English & Welsh male mortality data. The models considered are:...

One of the key motivations in the construction of ever more sophisticated mortality models was the realisation of the importance of “cohort effects” in the historical data. However, these are often difficult to estimate robustly, due to the identifiability issues present in age/period/cohort...

A particularly important issue in retirement income provision is longevity risk. There are two components to longevity risk. The first is the uncertainty over how long any particular pension scheme member is going to live after retirement. This is known as idiosyncratic longevity risk. Both...

In the first part of the paper, we consider the wide range of extrapolative stochastic mortality models that have been proposed over the last 15-20 years. A number of models that we consider are framed in discrete time and place emphasis on the statistical aspects of modelling and forecasting....
