Should retirement age be coupled to life expectancy ? [PDF]

open access: yesarXiv, 2003
Increasing every year the retirement age by the same amount as the increase of the life expectancy gives roughly stable ratios of the number of retired to working-age people in industrialized countries. Continuous influx of immigrants, below one percent per year of the total population, is needed for this stabilization.

Life Expectancy at Current Rates vs. Current Conditions

open access: yesDemographic Research, 2002
Life expectancy is overestimated if mortality is declining and underestimated if mortality is increasing. This is the fundamental claim made by Bongaarts and Feeney (2002) in their article "How Long Do We Live?", where they base their claim on arguments ...

Does Physical Activity Increase Life Expectancy? A Review of the Literature

open access: yesJournal of Aging Research, 2012

On Representing the Mean Residual Life in Terms of the Failure Rate [PDF]

open access: yesMathematical and Computer Modelling, Vol. 37 (2003), no. 12--13, pp. 1271--1280. MR1996036 (2004e:62181), 2004
In survival or reliability studies, the mean residual life or life expectancy is an important characteristic of the model. Whereas the failure rate can be expressed quite simply in terms of the mean residual life and its derivative, the inverse problem--namely that of expressing the mean residual life in terms of the failure rate--typically involves an

Efficiency in Lung Transplant Allocation Strategies [PDF]

open access: yesarXiv, 2018
Currently in the United States, lung transplantations are allocated to candidates according to the candidates' Lung Allocation Score (LAS). The LAS is an ad-hoc ranking system for patients' priorities of transplantation. The goal of this study is to develop a framework for improving patients' life expectancy over the LAS based on a comprehensive ...

Gamma-Gompertz life expectancy at birth

open access: yesDemographic Research, 2013
BACKGROUND The gamma-Gompertz multiplicative frailty model is the most common parametric modelapplied to human mortality data at adult and old ages. The resulting life expectancy hasbeen calculated so far only numerically.

Lifesaving, lifetimes and lifetables

open access: yesDemographic Research, 2005
Mortality change roils period rates. In the short term, conventional calculations of age-specific probabilities of death and life expectancy in the period immediately after the change depend on how many lives have been saved.
