Empirical demand systems that do not impose unreasonable restrictions on preferences are typically non-linear. We show, however, that all popular systems possess the property of conditional linearity. A computationally attractive iterated linear least squares estimator (ILLE) is proposed for...

L'article étudie l'impact de la structure économique locale sur la croissance locale de l'emploi. Cette croissance de l'emploi est décomposée en croissance interne (la croissance de la taille des établissements) et croissance externe (la création de nouveaux établissements). Les auteurs...

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...

Les auteurs formalisent un modèle d'équilibre à deux composants : les négociations salariales et la recherche d'emploi afin d'apporter un éclairage nouveau sur la détermination des salaires en France. Trois déterminants essentiels sont pris en compte : productivité, compétition entre...

The purpose of this paper is to study the trade-off between purchases and home production of food. We develop a simple household production model which predicts a zero elasticity of home production with respect to total expenditure. Focusing on vegetables, we use data from the 1991 French...

In this paper we study household purchase behaviour of storable food products. An inventory model is developed in which the household chooses an optimal stock level of the product. Storage of the product is costly, there is a fixed cost per purchase occasion, and the market price is sometimes...

In this article we develop an equilibrium search model with a continuous distribution of firm productivity types within a given labor market. We characterize equilibrium, derive expressions for the endogenous equilibrium wage distributions, and characterize the set of wage distributions that can...

In this paper we consider a joint model for frequency of purchase and consumer demand. We discuss sufficient identifying assumptions for the estimation of consumer demands from survey data for the general case of nonlinear (or linear) Engel curves. Moreover we show that in many cases the actual...
