[[A model of parent/child coresidence, taking into account postnuptial competition]]

An analysis of coresidence patterns among parents and their children is presented. The author develops a two-sex model to show that what he defines as coresidability "is affected not only by the competition among children's siblings concerning the coresidence with their parents, but also by the competition between the siblings of the children and the siblings of children's spouses concerning the coresidence with parents and by the competition between the parents and the parents of children's spouses concerning the coresidence with their children."
