Travail de recherche/Working paper
Résumé : Household decisions are one of the key elements impacting many dimensions of any economy. In this paper, we review the economic literature onfamily types, focusing on nuclear, stem, and complex families. We show that family types are heterogeneous across and within countries, both inthe past and in present times. We argue that economists have focused too much their analysis on nuclear families, which may limit our capacity toanalyze the impact of institutional phenomena or public policies. We establish how each family type could relate to the basic ingredients of standardstructural models of household decisions. We believe this overview sets the stage for an interesting research avenue to improve the structural models of household decision making.
