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...

Contrary to Tests of Hypotheses intended to verify a priori hypotheses regarding relations between variables, Exploratory Data Analysis (EDA) is used to search and discover systematic relationships between variables by taking into count a large number of variables. In these exploratory...

In this paper, we first give an elementary proof of existence of equilibrium with dividends in an economy with possibly satiated consumers. We then introduce a non-arbitrage condition and show that it is equivalent to the existence of equilibrium with dividends.

We study the two-staged fixed orientation constrained two-dimensional two-staged cutting stock problem. We solve the problem using several approximate algorithms, that are mainly based upon a strip generation procedure (HESGA) already developed in ([13)]. We evaluate the performance of these...

We characterize asymmetric equilibria in two-stage process innovation games and show that they are prevalent in the different models of R&D technology considered in the literature. This leads to a reassessment of the potential benefits of research cooperative agreements. Indeed, cooperation in...

This paper considers a two-period model of endogenous human capital formation under the credits-market imperfection and uncertainty assumptions. We compare in the first part of the paper ex-ante and ex-post general-equilibrium effects of the education subsidy policy to those of the negative...

We adapt the model of comparisons of experts initiated by Lehrer (“Comparison of experts JME 98”) to a context of uncertainty which cannot be modelised by expected utility. We examine the robustness of Lehrer in this new context. Unlike expected utility, there exist several ways to define...
