We consider a general equilibrium model with a production sector. The consumption sets, the preferences of the consumers and the production possibilities are represented by set-valued mappings to take into account the possibility of external effects. There are no convexity assumptions on the...

We present a simple and direct proof for a nonlinear Leray-Schauder type alternative for a large class of condensing or compact set-valued maps, containing convex as well as nonconvex valued maps.

Notre reflexion dans ce papier concerne la relation entre les IDE, le capital humain et la croissance dans les pays en cours d'industrialisation. Ces pays hotes multiplient les politiques incitatives d'investissements, afin de beneficier le plus possibles des retombees positives des...

The purpose of this paper is to show that the lattice Sn of permutations on a n-element set is bounded. This result strengthens the semi-distributive nature of the lattice Sn. To prove this property, we use a characterization of the class of bounded lattices in terms of arrows relations defined...

This paper studies the determinants of location choice by foreign investors in France. A new sample of almost 4000 location choices over 10 years and 92 administrative locations is used to measure two important issues : To what extent do foreign investors cluster spatially and are the decision...
