How life expectancy varies with perturbations in age-specific mortality
By Tomasz Wrycza, Annette Baudisch
This article is part of the ongoing Special Collection 8 „Formal Relationships“
Abstract
Background: A naturally arising question in demography is how a given change in mortality affects life expectancy. Scholars have targeted this question with different aims and from different perspectives.
Objective: We present and prove the central relationship between change in mortality and resulting change in e0, and we systematically apply it to investigate the effect of specific mortality perturbations.
Comments: Expressions for the change in e_0 resulting from a change in the parameters of the standard parametric mortality model in demography, the Gompertz-Makeham model, include well-known demographic quantities, which might prove useful for future studies.
