Many studies specify human mortality patterns parametrically, with a parameter change affecting mortality rates at different ages simultaneously. Motivated by the stylized fact that a mortality decline affects primarily younger people in the early phase of mortality transition but mainly older...

Cet article montre qu'un modèle néo-classique, aux hypothèses habituelles mais pourvu d'une structure par âge de la population explicite, converge vers son sentier de croissance équilibré avec des oscillations amorties. Il reproduit ainsi un processus de retour à la moyenne avec...

This paper develops an overlapping-generations (OLG) model to analyze the consequences of demographic structure changes induced by an exogenous shift in the birth rate.We first show that a finite growth rate of the population that maximizes long-run capital per capita exists. Then, we examine...

In this article, overlapping generations are extracting a natural resource over an infinite future. We examine the fair allocation of resource and compensations among generations. Fairness is defined by core lower bounds and aspiration upper bounds. The core lower bounds require that every...

This paper studies the intertemporal equilibrium of a barter economy populated with a continuum of …finitely-lived overlapping generations. Assuming isoelastic preferences and zero endowments at the beginning and the end of the individual's life-span, it proves the existence of an Hopf...

In this paper, we develop a continuous time overlapping generations model to analyze the relationship between demographic growth rate and the interest rate. We show there exists a finite demographic growth rate that minimizes the interest rate. This implies that the relation between the two...

Age structured populations are studied in economics through overlapping generations models. These models allow for a realistic characterization of life-cycle behaviors and display intertemporal equilibrium that are not necessarily efficient. This article uses the latest developments in...

Human knowledge has always been an object of research. Social systems have generated huge Knowledge Capital, depending on their project and their environment. These sets of knowledge are structured as systems, and are new research objects. Analysis of such systems are of great importance in our...

Pendant de nombreuses années, la recherche en gestion des connaissances s'est intéressée à l'élaboration, pour le niveau opérationnel de l'entreprise (les métiers), de méthodes, outils et démarches de repérage, de préservation, de formalisation, d'enrichissement et de valorisation des...

: MOISE est une méthodologie de gestion de la connaissance qui comporte une étape de spécification de la connaissance, laquelle distingue la connaissance statique de la connaissance dynamique. Cette étape met en œuvre un langage de représentation de la connaissance graphique (LRC) qui...
