We consider a capital accumulation game between two different jurisdictions. When the jurisdictions adopt open loop strategies, we study the inefficiency of the steady state Nash equilibrium with respect to the steady state utilitarian solution.

We study cycles and chaos in economic models. Autonomous dynamical systems are considered through infinite time horizon optimization models. We first show how endogenous fluctuations arise in a multisector growth model. Secondly, we consider an extension of this model by allowing direct...

Dans le cadre d'un modele de croissance a generations imbriquees avec agents heterogenes, on analyse dans cet article les consequences en termes de croissance et de chomage de politiques publiques de subvention a l'education.

We consider an overlapping generations model of small open economy with Harrod neutral technical progress. If the interest rate is less that the growth rate, intergenerational public transfers increase welfare of some generations and reduce welfare of others.

We consider infinite horizon variational problems on different spaces of curves in presence of constraints on the state. We establish several necessary conditions of optimality, and give relations between these different problems.

Nous montrons dans cet article que les contraintes de salaire minimum legal peuvent exercer des influences favorables sans qu'il soit necessaire de faire reference a des externalites. Plus precisement, si l'economie concurrentielle admet plusieurs equilibres stationnaires, il existe toujours un...

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...

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...
