Economies of scale are defined using a general form of Barten scales. We identify resource sharing among household members and, originally, the contribution of each parent to the expenditure on children. We provide a tractable estimation approach based on a simple demand system for male and female clothing, that is, two exclusive goods commonly available in standard surveys. We illustrate the method on thirty years of expenditure data for the UK. We relax the independence of the sharing rule on total expenditure and actually find that women’s shares increase with living standards. This, and progress in education levels, explains most of the reduction in intra-household inequality over the period.

We thank François Bourguignon for useful comments and suggestions. We bear the sole responsibility for any remaining errors. In Chiappori’s (1988) collective model of labor supply hours of work are supposed flexible. In many countries, however, male labor supply does not vary much. In that case, the husband’s labor supply is no longer informative about the household decision process and individual preferences. To identify structural components of the model, additional information is needed. We thus consider an approach in which the wife’s labor supply is expressed as a function of the household demand for one specific good. We demonstrate that the main properties of Chiappori’s initial model are preserved and apply our results on French data.

The first section discusses the unitary approach, in which the individual behavior model is simply transposed to the household. However, this approach is hindered by a lack of reliable theoretical justifications for the necessary aggregation of individual preferences and by the rejection of the predictions it generates. Therefore, economists have developed a more general, collective approach. Based on the assumption of optimal resource allocation, this approach accounts for multiple decision makers within one household. The most recent research examines new generalizations in which the efficient situation is merely a particular case.

Firstly, we show that the main structural components of the decision process, in particular, the price of leisure, can be retrieved. Secondly, we estimate a system of market and domestic labor supply using the PSID and apply the theoretical results.

It is shown that the structural components of the model can be identified without a distribution factor, thereby generalizing the initial results of Apps and Rees (1997) and Chiappori (1997). The theoretical model is then estimated using the ATUS data. The empirical results are compared to those obtained from a similar model without domestic production.

Each household member is characterized by specific prefer- ences and the (unspecified) allocation process is assumed to be efficient. Following the principle of the Rothbarth approach, the identification of the children's share requires the observation of adult-speci?c goods. The share of household income accruing to children in this context o¤ers a new measure of the cost of children, i.e., it differs from the traditional approach in that it is compatible with economies of scale and parents'bargaining. We illustrate the method with an application on the French Household Budget Survey.

The main results are based on a conditional demand ("m-demand")

First, we develop a model of labour supply which generalizes most specifications that can be found in the literature. Then, we study the properties of testability and identifiability of this model and its variations. Finally, we present empirical tests using PSID data.

Je montre, ensuite, que le processus de décision peut être décrit par un équilibre de Lindahl. Les dotations, les préférences et les prix du bien public de chacun des membres du ménage peuvent être retrouvés à partir de l'estimation des fonctions

We identify and estimate scale economies in households and the sharing rule between husband, wife and children. While adult shares and economies of scale are identi ed thanks to the estimation of individual Engel curves on single individuals, the identi cation of the resource share accruing to children (the cost of children) requires the observation of adult-speci c goods as in the traditional Rothbarth method. The useful aspect of the present approach is that it requires only the estimation of Engel curves on cross-sectional data, i.e. price variation is not required. This is an advan- tage for many countries where price variations is indeed limited, as in our application on Irish data.

Nous tenons explicitement compte de l'impôt sur le revenu et des prin- cipales prestations familiales. Nous constatons que les données ne valident que partiellement les restrictions engendrées par la rationalité collective. Néanmoins les estimations eectuées nous informent sur les arrangements internes au sein du couple. En particulier, nous observons que, lorsque la menace de divorce de l'épouse est plus crédible, celle-ci reçoit une part plus importante des ressources.

In this paper, we estimate the allocation process and adult economies of scale in households from Côte d'Ivoire using a collective model of household consumption. Identi…cation relies on the observation of adult-speci…c goods, as in the Rothbarth method, and a joint estimation on couples and singles. Results show that children's shares are small and decline quickly with household size. It results that child poverty, measured on the basis of individual allocations within families, is much larger than in traditional measures ignoring intrahousehold inequality. Adult poverty is smaller because parents are highly compensated by the scale economies due to joint consumption.

The household behavior is represented according to the collective approach. That is, each household member is characterized by specific preferences. Following the principle of the Rothbarth approach, the identification of the children's share requires the observation of adult-specific goods. Our method differs from this traditional approach in that it is compatible with economies of scale as well as with parents' bargaining. We illustrate the method with an application to the French Household Budget Survey.

The main results are based on a conditional demand (‘m-demand’) framework in which household demands are directly derived from the marginal rates of substitution. We show that (i) household demands have to satisfy testable constraints and (ii) some elements of the decision process can be retrieved from observed behavior. These theoretical considerations are followed by an empirical application using the U.S. Consumer Expenditure Survey. Overall, it turns out that the data are consistent with the theoretical model.

Cependant, de- vant les limites de cette maniere de proceder, telles que l'absence de justifications theoriques convaincantes de la necessaire agregation des preferences individuelles, ils ont developpe une approche plus generale basee sur la seule hypothese d'efficacite de l'allocation des ressources. Depuis, les recherches les plus recentes ont considere de nouvelles generalisations des modeles existants ou la situation efficace est seulement un cas particulier.

Following the principle of the Rothbarth approach, the identification of the children's share requires the observation of at least one adult-specific good. However, our method differs from this traditional approach in that it allows measuring economies of scale in the household and indifference scales in Lewbel (2003)'s sense. We illustrate the method with an application on the French Household Budget Survey.

Il repose sur l'hypothese que le parcours scolaire des eleves peut etre decrit par un processus de Markov. Sur la base d'un echantillon transversal d'un millier d'enfants, en fonction de variables socio-economiques et pour chacune des annees de scolarite obligatoire, les probabilites individuelles de poursuivre un parcours scolaire « normal », c.-a-d. Sans redoublement ni relegation dans une filiere de second choix, sont estimees. Nos resultats montrent que derriere les substantiels taux agreges de redoublement qui caracterisent le systeme scolaire belge se cachent en fait de profondes inegalites sociales.

In the case where one spouse does not participate in the labour market, her market wage does no longer coincide with the price of leisure. The price of leisure must be computed by the marginal rate of substitution between leisure and consumption. It is then shown that the structural components of the model can be identified. These theoretical considerations are followed by an empirical application using the ATUS data.
