Parikh and Krasucki [1990] showed that if rational agents communicate the value of a function f according to a protocol upon which they have agreed beforehand, they will eventually reach a consensus about the value of f, provided a fairness condition on the protocol and a convexity condition on...

In cooperative game theory, the Shapley value is a central notion defining a rational way to share the total worth of a game among players. In this paper, we address a general framework, namely regular set systems, where the set of feasible coalitions forms a poset where all maximal chains have...

This research takes an interest to the gap between employment and education of young people in the survey Generation 98 of Cereq. This research compares the positions of young people who are recruited on jobs with classic status and subsidised jobs. A lot of people are downgrading because their...

The positive effect of a common currency on trade is empirically well-documented, but the reason of this effect remains unclear. In this paper, we argue that part of the currency union effect on trade is indirect. Currency unions foster foreign direct investment (FDI), which promotes trade due...

We consider a class of pure exchange economies with externalities. The consumption set and the preferences of each household depend on his initial endowment and on the actions of the other households. We give a definition of competitive equilibrium with externalities which includes as particular...

This document starts from the statement that all human resources themes can generate risks of inequalities and discrimination between men and women. Of course, these discriminations are indirect but the results is the same about recrutment, careers, wages, balance between family life and work,...

This article aims at testing the convergence hypothesis in MENA region using new tests of a unit root in panel data. Quah (1994, 1998), Evans & Karras (1996) and Bertrand & Jones (1996) recommend this technique to evaluate the income convergence hypothesis. According to them it avoids...

This paper presents an axiomatic model of decision making which incorporates objective but imprecise information. We axiomatize a decision criterion of the multiple priors (or maxmin expected utility) type. The model achieves two primary objectives. First, it explains how subjective belief...

The identification question raised by Lewbel in the estimation of equivalence scales is empirically discussed using Polish panel data for two sets of four consecutive years (1987-90 and 1997-2000). The value of the equivalence scale estimates varies considerably when dynamics of family formation...

This paper deals with the existence of marginal pricing equilibria or equilibria with general pricing rules in an economy with increasing returns to scale or more general types of non convexities in production. Its main contribution is to posit the bounded loss and survival assumptions on a...
