The influence of relative wealth on fairness considerations is analyzed in an ultimatum game experiment in which participants receive large and widely unequal initial endowments. Subjects initially demonstrate a concern for fairness. With time however, behavior becomes at odds with both subgame...

We apply several recently proposed tests for structural breaks in conditional variance and covariance dynamics. The tests apply to both the class of ARCH and SV type processes and allow for long memory features. We also apply them to data-driven volatility estimators using high-frequency data...

Les relations entre les variables sociodémographiques et la pauvreté ont été étudiées à partir des données issues du recensement général de la population et de l'habitation de 2002 avec un modèle de régression fondé sur les caractéristiques d'habitation et les conditions de vie des...

This paper proposes an indirect inference (Gourieroux, Monfort and Renault, 1993; Smith, 1993) estimation method for a large class of dynamic equilibrium models. Our approach is based on the observation that the econometric structure of these systems naturally generates auxiliary equilibria that can...

The excess liquidity of commercial banks is very often mentioned in the CEMAC as one of the limits of monetary policy implementation by BEAC. In this paper, we tried to address excess reserves in the CEMAC banking system looking from the point of view of commercial banks. Indeed, commercial...

The objective of this work is to evaluate and explain technical efficiencies of Banks in CEMAC zone. We use dynamic non parametric approach to estimate efficiencies scores and non parametric regression to explain inefficiencies. Our estimates shows that credits react positively to deposits but...

We discuss statistical inference problems associated with identification and testability in econometrics, and we emphasize the common nature of the two issues. After reviewing the relevant statistical notions, we consider in turn inference in nonparametric models and recent developments on...

This paper proposes a new nonparametric test for conditional independence, which is based on the comparison of Bernstein copula densities using the Hellinger distance. The test is easy to implement because it does not involve a weighting function in the test statistic, and it can be applied in...

We use a multivariate hazard model to analyse the ratification behaviour of ILO conventions by developing countries. The model accounts for two random effects: one at the country level, the other at the convention level. After investigating identification, we use a semi-parametric Bayesian...

Compte tenu de l'importance de l'étude de la dépendance extrême, nous avons essayé de déterminer l'approche qui semble être la meilleure pour l'étude des risques extrêmes. Pour atteindre ce but, nous avons mené une étude du coefficient de dépendance de queue pour les trois approche :...
