A l'aide d'un modele a generations imbriquees avec production nous etudions une economie dans laquelle coexistent des agents altruistes et egoistes dont les offres de travail sont endogenes. Nous montrons comment les caracteristiques d'un type d'agent influencent le comportement de l'autre...

This paper looks at the issue of existence and stability of steady state equilibria in an overlapping generations model with productive capital (a-la Diamond) augmented to include endogenous labour supply. The paper derives necessary and sufficient conditions under which a steady state...

Nous considerons un modele dans lequel l'accumulation de capital huamin depend de deux inputs: l'effort prive d'education des individus et le poids du systeme educatif public represente par son taux d'encadrement. Ce dernier depend notamment du pourcentage d'enseignants qui est choisi par les...

This paper considers a model of oligopolistic competition and locational choice that incorporates the notion of regional industrial systems. Firms play a non cooperative game where the strategy set of firms is given by a set of existing industrial districts. Each firm is distinguished by its...

This paper establishes a B-core existence result for normal form TU games.

Unlike partial equilibrium analysis which study the equilibrium of a particular market under the clause "ceteris paribus" that revenues and prices on the other markets stay approximately unaffected, the ambition of a general equilibrium model is to analyze the simultaneous equilibrium in all...

In past years, imperfect competition has been introduced in several dynamic models to show how mark-up variability, increasing returns (decreasing marginal cost) and monopoly profits affect the occurence of endogenous fluctuations. In this paper, we focus on another possible feature of...

In this paper, we address the question of deterministic cycles in a Ramsey model with heterogeneous infinite-lived agents and borrowing constraints, augmented to take into account the case of elastic labor supply. Under usual restrictions, not only we show that the steady state is unique, but...
