Cette note considere un eeconomie d'echange a deux periodes dans laquelle les dotations sont incertaines. En plus de cette incertitude economique, existe une incertitude pesant sur les paiements des actifs financiers. Les agents ont des croyances non-additives en ce qui concerne l'incertitude...

Cet article propose une evaluation critique de ce que le courant néoclassique appelle la "nouvelle theorie" de la croissance. Il analyse ce qu'est la "croissance endogene", en presentant, dans une premiere partie, les origines, mecanismes et catégories de modèles à progres technique...

We give a simple example to the non-existence of duopoly equilibrium in pure strategies in an economy with two goods and two types of consumers.

In this paper, it is proved that in the case of pure exchange economy, the oligopoly equilibrium leads to the competitive equilibrium when the economy is replicated an infinite number of times.

We present a version of the APT based on an asset index set of an arbitrary infinite cardinality. Under assumptions due to Ross and Chamberlain-Rothschild, we shhow that in the absence of gains from asymptotic arbitrage, the square of the deviations of the individual rates of return from a...

In this paper, we first give a direct proof of the existence of Edgeworth equilibria for exchange economies with consumption sets which are (possibly) unbounded below. The key assumption is that the individually rational utility set is compact. It is worth noticing that the statement of this...

Inspite of wide and lond-standing support among economists for indexation of loan contracts there has been relatively little use of indexation, except in situations of extremely high inflation. The object of this paper is to provide a (theoretical) explanation for this puzzling phenomenon based...

This paper investigates and provides a comparison of the short- and long-run effects of technological progress on employment. It presents a simple standard model of matching unemployment that captures the negative creative destruction effects of technological change on employment. In the...

Ce texte constitue un complement a la presentation generale, non formelle, du modele CLFPSR faite dans [6]. Il contient une presentation systematique de la structure du modele, en termes d'economie mathematique, quoique elementaires: types de donnees et de variables, systeme de contraintes,...
