In this paper we first prove an equilibrium existe theorem for finite dimensional economies with unbounded below consumption sets. We only assume that the individually rational utility set is compact and use the demand approach instead of the standard Negishi's approach. We next compare the...

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...

This paper proposes to explain why there are so many guests in African households and to determine the consequences on individual behaviors. The starting point is the assumption that there exists, in traditional societies, a norm, together with a system of sanctions, which states that within the...

This paper investigates the stability of households' consumption behaviour in France through a prcedure of discriminating between feedback and feedforward models connected to the notions of encompassing in invariance initially proposed by Hendry (1988).

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...

This article is aimed at the reconsideration of Ramsey long-run distribution concerns, i.e., the so-called impatience problem, when consumption paths display homothetic growth. Is it possible for heterogeneous agents to survive in the course of an equilibrium characterised by a common growth...

In this paper, we study the intertemporal equilibria of an infinite-lived representative agent model with public debt. We show that for a given path of government expenditures, there generally exist a continuum of equilibria depending on various debt policies.

The general purpose of this paper is to prove quasiequilibrium existence theorems for production economies with general consumption sets in an infinite dimensional commodity space, without assuming any monotonicity of preferences or free-disposal in production.
