This paper is aimed at discussing the description of an efficiency index as a metric distance, and its relationship to the profit function.

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...

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...

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...

This paper discusses the influence of technological externalities on the dynamic properties of accumulation paths in a two-sector growth model in discrete time.
