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...

L'auteur définit dans un premier temps les systèmes complets de demande. Dans un deuxième temps, il décrit le modèle AIDS de Deaton et Muellbauer puis propose une méthode d'estimation des systèmes de demande à partir du modèle. Il termine sur les limites de cette méthode.

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...

We study the macrodynamics of sorting between workers and firms.

In this paper we design a search-matching models similar to that can both explain the formation of couples and select the equilibrium on the curve of optimal contracts. We study identification from cross sections. The model is non parametrically estimated using the SIPP data.

This paper analyzes the career progression of skilled and unskilled workers, with a focus on how careers are aected by economic downturns and whether formal skills, acquired early on, can shield workers from the eect of recessions. Using detailed administrative data for Germany for numerous...
