摘要：La théorie de l'allocation du temps de Becker (1965) permet, par l'intégration de fonctions de production domestique à une fonction d'utilité directe, de proposer une nouvelle méthode d'estimation des élasticités-prix qui est appliquée à un appariement d'une enquête INSEE de Budgets des Familles avec une enquête de Budgets-temps. Le modèle fournit également la possibilité d'estimer le coût d'opportunité du temps des ménages et l'élasticité de leur offre de travail marchand par rapport au taux de salaire.
其他摘要：This article adopts Becker's allocation of time framework to describe households' choices concerning both their monetary and time use expenditures in order to propose a new method to derive price elasticity at a micro level. Price and full income elasticities are estimated on a matching of a French Family Budget and a Time Use survey. The utility and home production functions are specified in order to allow the computation of the household's opportunity cost for time, which is shown to be smaller in average than the household's wage net of taxes. This estimate serves to value time dedicated to domestic activities and are used in the definition of full prices. The estimated price elasticities compare well with the estimates by other methods, such as Frisch's model based on independence of preferences assumptions or Hicks-Lewbel's method based on the aggregation of commodities. Finally, the model is applied to the computation of a welfare index, to the estimation of the household's labour supply and to a tentative explanation of the classic difference between cross-section and time-series estimates of income elasticities.
