We consider an economy in which a central government has to decide on the provision and location of an emergency public service the quality of which diminishes with distance. The emergency service has to attend a group of municipalities geographically located in a star-tree-graph. We derive the...

We introduce an AK spatial growth model with a general geographical structure. The dynamics of the economy is described by a partial differential equation on a Riemannian manifold. The morphology interacts with the spatial dynamics of the capital and is one determinant of the qualitative...

Cet article propose d’analyser le lien entre la stabilité d’un cartel et les problèmes qui ont prévalus à sa formation. Pour cela nous reconsidérons, dans un contexte dissymétrique, les concepts de stabilité proposés à l’origine par d’Aspremont, Jacquemin, Gabszewicz et Weymark...

In this paper, we solve a Solow model in continuous time and space. We prove the existence of a solution to the problem and its convergence to a stationary solution. The simulation of various scenarios in the last section of the paper illustrates the convergence issue

Cet article démontre sous son jeu d'hypothèses (notamment la présence de gouvernements prédateurs) que le découpage spatial de l'activité publique -recettes et dépenses- peut avoir une efficacité en terme de taux de croissance. Dans un premier temps, on traitera de l'organisation...

We develop a tractable general theory for the study of the economic and demographic impact of epidemics, and notably its distributional consequences. To this end, we develop a three-period overlapping generations model where altruistic parents choose optimal health expenditures for their...

This paper analyses the impact of foreign health aid on the emigration rates of physicians. We use a panel database to investigate the emigration of physicians from 192 source countries to 17 destination countries between 1995 and 2004. First, we investigate the direct impact of health...

We develop a tractable general theory for the study of the economic and demographic impact of epidemics. In particular, we analytically characterise the short and medium term consequences of epidemics for population size, age pyramid, economic performance and income distribution. To this end, we...
