This empirical paper proposes to explain why African households often provide long-term hospitality to relatives. We use a budget and consumption survey carried out in Gabon in 1994, examine two types of hypotheses and propose a two-step procedure to discriminate between them. We address the...

Apres un rappel synthetique des differents concepts d'exogeneite dans les cadres stationnaire et non stationnaire (predetermination, exogeneite stricte, exogeneite faible, exogeneite forte, super exogeneite, exogeneite de cointegration), nous examinons les conditions d'exogeneite faible...

This paper presents a discrete time version of the Romer 1986 model of endogenous growth. The purpose of this work is to propose detailed and simple proofs of existence of optimal solutions and of a competitive equilibrium. The framework implemented here reduces the complexity of the proofs...

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.
