On Longevity

Education Externalities on Longevity∗

We argue that education exerts positive external effects on health, beyond the standard internal effects documented in the literature. We implement an innovative approach to control for endogeneity and omitted variables problems and present evidence for the significant role played by higher education in explaining longevity across countries. Our findings provide empirical evidence in support of...

Complementarity principle on human longevity

In recent we introduced, developed and established a new concept, model, methodology and principle for studying human longevity in terms of demographic basis. We call the new model the " Weon model " , which is a general model modified from the Weibull model with an age-dependent shape parameter to describe human survival and mortality curves. We demonstrate the application of the Weon model to...

Evidence on Individual Preferences for Longevity Risk

Evidence on Individual Preferences for Longevity Risk The standard model of intertemporal choice assumes risk neutrality toward the length of life: due to additivity, agents are not sensitive to a mean preserving spread in the length of life. Using a survey fielded in the RAND American Life Panel (ALP), this paper provides empirical evidence on possible deviation from risk neutrality with respe...

Igf-I signaling and effects on longevity.

Insulin and insulin-like signaling regulate survival and lifespan in a variety of animal species, from nematodes and flies to higher vertebrates and mammals. Recently, it was shown that brain IGF-I receptor and brain IRS2 control mammalian lifespan, and that this occurs through neuroendocrine mechanisms, control of energy metabolism and modified stress resistance. Furthermore, it was demonstrat...
