In this paper we start from a continuous time framework derived from the classical predator-prey model in order to analyze the recent dynamics of regional evolution in the EU. The model describes a system of interrelated units obeying a complex functional dynamics that at any moment may...

The standard approaches used in the empirical literature to test economic convergence-divergence between countries and regions are all grounded on the Mankiw-Romer-Weil and Barro-Sala-i-Martin contributions that led to the celebrated b-convergence model. Such a model, however, presents strong...

Why do industrial clusters occur in space? Is it because industries need to stay close together to interact or, conversely, because they concentrate in certain portions of space to exploit favourable conditions like public incentives, proximity to communication networks, to big population...

[fre] Modèles urbains dynamiques: étude critique. . L'article passe en revue les principales contributions récentes à la dynamique économique urbaine. Les trois méthodes d'approche — modèles théoriques, simulations sur ordinateur, économétrie urbaine — sont soigneusement évaluées...

The paper describes a spatial economic equilibrium in which each market shows an equilibrium and the location of all producers is determined in an optimal way. Being a very general model, in order to solve it a number of hypotheses had to be introduced. We used the hypothesis of Tinbergen and...
