The configurational studies of this special issue trace complex patterns of interdependencies existing among family members and beyond households. They focus on the functional connections among spouses, children, siblings, and other relatives living in a variety of households. The main goal of this special issue is to reveal how some key decisions and exchanges occurring in family dyads, such as the marital and parent–child dyads, are embedded within a larger set of family and interpersonal exchanges that constitute configurations of their own in a variety of contexts.
