Résumé : We make use of rich micro data from the Belgian MEqIn survey, which contains detailed information on individual consumption, public consumption inside households and time use. We explain the observed household behavior by means of a collective model that integrates marriage market restrictions on intrahousehold allocation patterns. We adopt a revealed preference approach that abstains from any functional form assumptions on individual utility functions or intrahousehold decision processes. This allows us to (set) identify the sharing rule, which governs the intrahousehold sharing of time and money, and to quantify economies of scale within households. We use these results to conduct a robust and meaningful individual welfare and inequality analysis, hereby highlighting the important role of detailed consumption and time use data.
