La théorie micro-économique entend réduire au maximum le nombre d'hy pothèses sur les goûts nécessaire à la construction des modèles de demande. Néanmoins aucun modèle n'atteint jamais la généralité absolue et certaines hypothèses sont même devenues tellement usuelles qu'on ne...

[eng] Two traditional assumption of dynamic demand models intertemporal separability and the recursivity of the utility function are here analyzed in detail .The kind of preferences underlying each utility function is first derived. We show that if separability easily accepts recursivity it is...

A constructive proof of identification of multilinear decompositions of multiway arrays is presented. It can be applied to show identification in a variety of multivariate latent structures. Examples are finite-mixture models and hidden Markov models. The key step to show identification is the...

In this paper, we document whether and how much the equalizing force of earnings mobility has changed in France in the 1990’s. For this purpose, we use a representative three-year panel, the French Labour Force Survey. We develop a model of earnings dynamics that combines a flexible...

In this paper,we construct a nonparametric estimator of the distributions of latent factors in linear independent multi-factor models under the assumption that factor loadings are known. Our approach allows to estimate the distributions of up to L(L+1)/2 factors given L measurements. The...

This paper develops a new concept of separability with overlapping groups—latent separability. This is shown to provide a useful empirical and theoretical framework for investigating the grouping of goods and prices. It is a generalization of weak separability in which goods are allowed to...

Most applications of Nash bargaining over wages ignore between-employer competition for labor services and attribute all of the workers' rent to their bargaining power. In this paper, we write and estimate an equilibrium model with strategic wage bargaining and on-the-job search and use it to...

We construct and estimate an equilibrium search model with on–the–job–search. Firms make take–it–or–leave–it wage offers to workers conditional on their characteristics and they can respond to the outside job offers received by their employees. Unobserved worker productive...

Dans cette étude, nous proposons un modèle de la dynamique salariale adapté à une estimation à partir de panels courts comme l’enquête Emploi. Nous utilisons le modèle pour simuler des trajectoires individuelles de salaires au-delà de la période d’enquête et calculer des revenus...
