Résumé : We first propose a new methodology to estimate the share of household income accruing to children (i.e., the cost of children). 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 the traditional Rothbarth approach in that it allows measuring economies of scale in the household and indifference scales in Lewbel (2003)’s sense. Our method can be applied within the unitary as well as within the collective framework. We then present an empirical illustration using the French Consumer Survey.
