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 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 paper constructs an overlapping generations model of pollution externality wherein individuals are altruistically linked to their offspring as in Barro (1974). It is shown that steady state consumption may be a decreasing function of the intergenerational degree of altruism. Despite...

This paper presents an overlapping generations model of environmental externalities with a depollution technology. each agent concerned by the environmental degradation can volutary contribute in order to reduce it. Contributing to the environmental quality means financing depollution activities...

We consider an overlapping generations model to study the effect of the educational system on growth and on the optimal educational policies when individuals are altruistic. The teaching efficiency depends on the teacher to pupil ratio; given a number of teachers, the number of students has a...

This article focuses on the scope for indeterminacies that originate from global capital stock externalities in the technological set of the reference model of the multisector optimal growth literature. These phenomena are shown to introduce a new class of intersectoral dependency in competitive...

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...

We consider the labour market implications of skill decay. State dependence in individual hazards emerges from the joint result of (optimal) hiring and search behaviours. We shed light on an original externality according to which firms' profits increase with the valuation of vacancies....

We consider a two-period overlapping generations economy in which individuals work in both periods and acquire skills when young through both learning-by-doing and formal education. We characterise the unique saddle-path stable steady state of this economy and show that individuals spend too...

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