Intergenerational transmission of longevity is not affected by other familial factors: evidence from 16,905 Dutch families from Zeeland, 1812-1962

ABSTRACT

Studies have shown that long-lived individuals seem to pass their survival advantage on to their offspring. Offspring of long-lived parents had a lifelong survival advantage over individuals without long-lived parents, making them more likely to become long-lived themselves. We test whether the survival advantage enjoyed by offspring of long-lived individuals is explained by environmental factors. 101,577 individuals from 16,905 families in the 1812–1886 Zeeland cohort were followed over time. To prevent that certain families were overrepresented in our data, disjoint family trees were selected. Offspring was included if the age at death of both parents was known. Our analyses show that multiple familial resources are associated with survival within the first 5 years of life, with stronger maternal than paternal effects. However, between ages 5 and 100 both parents contribute equally to offspring’s survival chances. After age 5, offspring of long-lived fathers and long-lived mothers had a 16-19% lower chance of dying at any given point in time than individuals without long-lived parents. This survival advantage is most likely genetic in nature, as it could not be explained by other, tested familial resources and is transmitted equally by fathers and mothers.

Longevity Ancient and Modern

The article examines illustrations from ancient and modern societies to consider the connections between power, social elites and knowledge of techniques to promote longevity. In pre-modern societies, knowledge of practices and substances to promote longevity were cultivated by elites such as the Chinese imperial court. In modern societies, new technologies—cryonics, cloning, stem-cell applications and nanotechnology—will offer exclusive and expensive methods for prolonging life for the rich. However one important difference between the ancient and modern world is that with secularization longevity is no longer connected with a moral life; longevity is not a reward for sanctity. We have democratized the ambition for long life but not necessarily its realization. The modern quest for longevity appears to be connected with the desire of Baby Boomer generations to hold on to their assets, but while modern medicine may help us to survive forever, it cannot tell us how to live forever.

Can underemployment persist in an expanding economy? Clues from a non-Walrasian OLG model with endogenous longevity

This paper aims at casting a new light on the persistence of underemployment in emerging economies, by examining the relationship between labour market imperfections and longevity changes. For that purpose, we develop a two-period OLG model where longevity depends positively on the real wage, but negatively on the underemployment level, which both result from wage negotiations between a trade-union, representing workers (i.e. young generation), and the management, representing capital-holders (i.e. old generation). The existence, uniqueness and stability of a non-trivial steady-state equilibrium are studied. The distribution of bargaining power is shown to be a major determinant of the short run and long run dynamics of employment, production and longevity. The dynamics is also shown to be significantly sensitive to the precise form under which job quality affects longevity.
