“…One explanation is that siblings may lack the necessary funds to offer larger gifts, as they are younger and had less time to accumulate savings (Demery & Duck, ). A second possibility is that the sibling relationship encompasses both cooperation and rivalry (Pollet & Hoben, ), since siblings compete with one another for their parents’ attention and resources, even in adult life (Taylor & Norris, ).…”

This study examines gift giving at Israeli weddings. In accordance with kin selection theory, we hypothesized that wedding guests possessing greater genetic relatedness to the newlyweds would offer greater sums of money as wedding gifts. We also hypothesized that family members stemming from the maternal side (where the genetic lineage has higher kinship certainty) would offer the newlyweds more money than those stemming from the paternal side. Data on the monetary gift sums of the wedding guests from 30 weddings were collapsed according to two criteria: (a) genetic relatedness (0%, 6.25%, 12.5%, 25%, and 50%) and (b) kinship certainty (maternal or paternal lineage). Both hypotheses were supported. We discuss the implications of these data in understanding family dynamics, as well as practical applications associated with the marketing of gifts.

“…Siblings share a common family heritage and, in the case of birth siblings, a common genetic background. Perhaps for this reason, the sibling relationship is normatively characterized as egalitarian, reciprocal, and mutual (Pollet and Hoben 2011). Siblings influence one another’s development, not only in childhood but throughout the life course (Kramer and Kowal 2005).…”

A Sibling Death in the Family: Common and Consequential

et al. 2012

Although a large literature analyzes the determinants of child mortality and suggests policy and medical interventions aimed at its reduction, there is little existing analysis illuminating the consequences of child mortality for other family members. In particular, there is little evidence exploring the consequences of experiencing the death of a sibling on one’s own development and transition to adulthood. This article examines the prevalence and consequences of experiencing a sibling death during one’s childhood using two U.S. data sets. We show that even in a rich developed country, these experiences are quite common, affecting between 5 % and 8 % of the children with one or more siblings in our two data sets. We then show that these experiences are associated with important reductions in years of schooling as well as a broad range of adult socioeconomic outcomes. Our findings also suggest that sisters are far more affected than brothers and that the cause of death is an important factor in sibling effects. Overall, our findings point to important previously unexamined consequences of child mortality, adding to the societal costs associated with childhood mortality as well as suggesting additional benefits from policy and medical innovations aimed at curbing both such deaths and subsequent effects on family members.

“…As people with significant disabilities are living longer into old age, the likely impact on the lives of nondisabled siblings will persist indefinitely. The sibling relationship is the longest-lasting family tie (Pollet & Hoben, 2011) and in this context our findings take on added significance even though our follow-up period ended in sibling’s midlife. Whether the difficulties in the lives of both siblings eventually disrupt the sibling relationship cannot be determined from the available data, but estrangement among siblings should be studied in future research, especially given the vulnerability and potential isolation of adults with disabilities as their parents age and after parental death.…”

Ripple effects of developmental disabilities and mental illness on nondisabled adult siblings

Developmental disabilities and severe mental illness are costly to the affected individual and frequently to their family as well. Little studied are their nondisabled siblings. Here we examine major life course outcomes (education, employment, and marriage) of these siblings in adulthood using data from the Wisconsin Longitudinal Study. Our sample comprises 113 individuals with developmental disabilities and 337 of their nondisabled siblings; 97 individuals with mental illness and 235 of their nondisabled siblings; and 17,126 unaffected comparison group members. We find that siblings of individuals with mental illness have less education and less employment than the unaffected comparison group, whereas those who have a sibling with developmental disabilities had normative patterns of education and employment, but less marriage and more divorce. Robustness tests incorporating genetic data do not change the conclusions based on the nongenetic analyses.
