Desiccation tolerance is defined as the ability to survive the removal of all, or almost all the cellular water without irreversible damage. It confers to dried...

So-called orthodox seeds can resist complete desiccation and survive the dry state for extended periods of time. During drying, the cellular viscosity increases...

Much research has been carried out and published on dairy replacement management, in order to rear heifers as efficiently as possible, from both a technical and...

An experiment was performed on 113 heifers born during three successive autumns (1987, 1988, and 1989) and aimed to study the effect of rearing strategy on...

This paper aims at investigating whether or not a utilitarian social planner should subsidize longevity-enhancing expenditures in an economy with a pay-as-you-go...

This paper studies the normative problem of redistribution between agents who can influence their survival probability through private health spending, but who differ...

Whereas existing OLG models with endogenous longevity neglect the impact of environmental quality on mortality, this paper studies the design of the optimal public...

Health spending obviously increase with capital per worker. This paper derives the optimal accumulation policy in such a context. The optimal accumulation rule depends...

Whereas longevity-adjusted consumption measures have become increasingly used as indicators of lifetime standards of living, it remained unnoticed that those measures,...

Growth models with endogenous mortality assume generally that life expectancy is increasing with output per capita and, thus, with individual consumption, whatever its...

This paper re-examines the spaceship problem, i.e. the design of the optimal population under a fixed living space, by focusing on the dilemma between adding new...

While there is a large empirical literature on the intergenerational transmission of health and survival outcomes in relation to lifestyles, little theoretical work...

This paper studies the optimal linear tax-transfer policy in an economy where agents differ in productivity and in genetic background and where longevity depends on...

Common sense supports prevention policies aimed at improving survival prospects among the population. It is also widely acknowledged that an early death is a serious...

Our research started with the following question: have longstanding family businesses been conducting sustainable development policies long before the word became a...
