Vintage capital growth models have been at the heart of growth theory in the 60s. This research line collapsed in the late 60s with the so-called embodiment controversy and the technical sophisitication of the vintage models. This paper analyzes the astonishing revival of this literature in the...

Le but de cet article est d' étudier comment la naissance et la croissance d'une économie est susceptible d'aff ecter le fonctionnement de son environnement mod elis e sous la forme d'un cycle naturel. A n de mettre en évidence les facteurs qui stabilisent le syst eme form e par le cycle...

Une communauté e d'individus h ét érog ene en terme de revenus occupe un territoire divis e en zones caract eris ées par des niveaux d'am enit es di fferents. Partant du concept de rente a la Ricardo, nous proposons un mod èle determinant les rentes o ffertes dans les diff erentes zones et...

Nous introduisons le concept d'empreinte carbone dans un mod èle o ffre globale et demande globale avec formation imparfaitement concurrentielle des prix et salaires et en examinons les propriétés de l' équilibre en présence d'une politique climatique. Nous étudions deux instruments...

The aim of this paper is to understand whether international trade may enhance innovation and growth through an increase in competition.We develop a two-country endogenous growth model, both countries producing the same set of goods, with firm specific R&D and a continuum of oligopolistic...

We develop a simple open-economy AK model with collateral constraints that accounts for growth-reversal episodes, during which countries face abrupt changes in their growth rate that lead to either growth miracles or growth disasters. Absent commitment to investment by the borrowing country,...

Consider a country with two regions that have developed differently so that their current levels of energy efficiency differ. Each region's production involves the emission of pollutants, on which a regulator might impose restrictions. The restrictions can be related to pollution standards that...

Les changements organisationnels reposant sur la polyvalence et les TIC qui se sont diffusés dans la plupart des pays de l'OCDE depuis les années 1990 ont de fortes conséquences sur les conditions de travail. Les données disponibles montrent, parallèlement à l'émergence de nouvelles...

We reconsider the optimal population size problem in a continuous time economy populated by homogenous cohorts with a fixed life span. This assumption is combined with a linear production function in the labor input and standard rearing costs. A general social welfare function is specified,...

Several contributions have already pointed out that initial wealth in- equalities do persist in the long run in the Ramsey model with heteroge- nous agents. We show that this result is not robust to the introduction of endogenous fertility. Our argument builds on the Barro-Becker (1989) seminal...
