Les regions sont devenues en France, avec les lois de decentralisation, des acteurs de la politique publique. Ce sont toutefois des acteurs dont l'identite economique reste incertaine. Les regions sont aujourd'hui au coeur d'un double reamenagement des relation verticales entre niveaux...

Cet article etudie la question des permis de pollution dans le cadre d'un modele a generations imbriquees: la pollution resulte de l'utilisation de l'environnement dans le processus de production et constitue un externalite negative qui vient diminuer l'utilite des agents.

We adress the issue of optimal growth when standard-of-living aspirations are transmitted from one generation to the next. We derive the condition for the optimal solution to be stable in the saddle-point sense and show that this optimal solution may display damped oscillations even when the...

This is a study in the field of unemployment and unemployability. I build an unclosed matching model of unemployment, where matching rates are exogenous. The value of an unfilled job depends on the average skill of the unemployed, who are supposed to lose (absolutely, or relatively) some of...

This paper studies relationships between the determinacy of a stationary equilibrium in the perfect foresight dynamics, and its local stability in dynamics arising from econometric learning procedures. There is no clear links in linear scalar economies where agents forecast only one perods...

In this ppaer we extend the Uzawa-Lucas endogenous growth model by including housing along three directions: as a households' provider of services and application for savings, as a productive sector (construction), and as an input in education and training activities. The consequences of this...

The preemptive role of capital is analysed in a class of two-player symmetric capital accumulation differential games with reversible investment. It is proved that, in the medium run, the firm with better initial condition exploits its advantage when the game features feedback substituability....
