The purpose of this paper is to study how the equilibrium, in a linear exchange equilibrium varies, with respect to the initial endowments and the utility vectors.

We study a class of exchange economies where the characteristics of the agent are fixed but the initial endowments. We define a notion of regular economies which encompasses the different approach of the literature. We then prove that a regular exchange economy has a finite odd number of...

We present a new result on the asymptotic behavior of non-autonomous subgradient evolution equations.

We first study the competitivity ratio for the on-line version of the problem of finding a maximum-order induced subgraph satisfying some hereditary property, under the hypothesis that the input graph is revealed by clusters. Next, we focus ourselves on two of the most known instantiations of...

This paper aims at measuring the robustness of Real Business Cycle international stylized facts across exchange rate regimes. I thus investigate th e impact of the Bretton Woods System and the ERM on the business cycle regularities. Thanks to bootstrap techniques, I measure the accuracy of the...

This paper presents and tests a model of cigarette consumption which mixes two types of intertemporal dependencies : habit-formation and learning about the health conseqences of smoking. This latter is argued to result from the observation of health developments, both one's own and those of...

Nous situons notre analyse dans le contexte de l'ouverture a la concurrence d'un bien reseau dans lequel l'operateur historique, integre verticalement, gere en monopole l'infrastructure et est concurrence sur les sectuers des services. La qualite du bien reseau est le minimum des qualite de...
