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 study the optimal dynamics of an AK economy where population is uniformly distributed along the unit circle. Locations only differ in initial capital endowments. Spatio-temporal capital dynamics are described by a parabolic partial differential equation. The application of the maximum...

We review an emerging application field to parabolic partial differential equations (PDEs), that's economic growth theory. After a short presentation of concrete applications, we highlight the peculiarities of optimal control problems of parabolic PDEs with infinite time horizons. In particular,...

We develop a tractable general theory for the study of the economic and demographic impact of epidemics. In particular, we analytically characterise the short and medium term consequences of epidemics for population size, age pyramid, economic performance and income distribution. To this end, we...

This paper solves a second-best problem where a government has in particular to choose whether to tax financial inflows (capital controls) or not, and when. A multi-stage optimal control technique is used to this end. First, it is shown that it is optimal to switch in finite time from capital...
