An early age at first marriage is known to be associated with a high risk of divorce. Yet, it has been suggested that beyond
a certain point, the relationship between age at marriage and marital instability may become positive because as unmarried
women begin to hear their biological clock tick, they may settle for matches far from the optimal. Analyses based on cycles
5 and 6 of the National Surveys of Family Growth show that the relationship between age at marriage and marital instability
is strongly negative up to the late 20s, with a flattening of the curve thereafter.

Given that savings behaviour and worker productivity have strong life-cycle components and given that demographic profiles
vary across countries, population age structure should be linked to differences in levels of economic development. In this
paper, we measure the economic importance of age structure variation for the global economy. We find that demographic maturation
has been associated with nearly half of the evolution of global per capita GDP since 1960. We also find that age structure
differences can account for just over half of the variation in worldwide per capita GDP (i.e. the lack of sigma convergence)
observed since 1960.

Previous studies have found that educational differences in mortality are weaker among the elderly. In this study I examine whether either cohort or period effects may have influenced the interpretation of age effects. Six 10-year birth cohorts are followed over 30 years through decennial censuses. Differential survival is inferred from changes in the relative proportions of a cohort in each education category as the cohort ages. In cross-section, younger persons generally show stronger education effects on survival, although this pattern is clearer for women than for men. There is evidence of period effects. Within cohorts, relative survival tends to increase with age. 相似文献

The claim that multiple partner fertility may pose a risk of adverse outcomes for children has not been tested. We test this argument using a sample of 4,027 resident fathers and children from the Fragile Families and Child Well‐being Survey by examining the pathways through which fathers' multipartnered fertility is associated with children's externalizing behaviors and physical health status at 36 months. Path analyses indicate that multiple partner fertility exerted both a significant direct and indirect effect through paternal depression to influence children's externalizing behaviors. Fathers' multiple partner fertility also exerted a significant indirect effect through one mediator—father involvement—to influence children's physical health. This evidence suggests that the disruptions brought about by multipartnered fertility are important for understanding child well‐being. 相似文献

This paper explores roles that children play in ethnographic research. Based on the limited literature on children in the
field, and drawing on examples from ethnographies across disciplines, I identify four roles for children: 1) as “wedges,”
or as instrumentally important in helping adult ethnographers gain access in various ways; 2) as collaborators; 3) as objects
of study; and 4) as subjects of study. I also discuss the ways in which these roles illuminate key methodological issues in
ethnography, like reflexivity, ethics, and agency. The paper synthesizes and integrates previously disconnected research on
the presence of children in the field with ethnographies in which children and childhood are the topics of research. I draw
on my own fieldwork experiences for further illustration.

This paper studies a class of social welfare relations (SWRs) on the set of infinite utility streams. In particular, we examine
the SWRs satisfying -Anonymity, an impartiality axiom stronger than Finite Anonymity, as well as Strong Pareto and a certain equity axiom. First,
we characterize the extension of the generalized Lorenz SWR by combining -Anonymity with Strong Pareto and Pigou–Dalton Equity. Second, we replace Pigou–Dalton Equity with Hammond Equity for characterizing
the extended leximin SWR. Third, we give an alternative characterization of the extended utilitarian SWR by substituting Incremental
Equity for Pigou–Dalton Equity. 相似文献

We consider the fraction of pairs of m distinct alternatives on which a social welfare function f may be nondictatorially independent and Pareto when the domain of f satisfies the free k-tuple property. When k = 4 we improve the existing upper bound to . When there are at least 26 alternatives and we obtain an original upper bound, . To obtain these results we define and analyze the graph formed from the nondictatorial independent and Pareto pairs and
combine the results of this analysis with known results from extremal graph theory.

We study necessary and sufficient conditions for a multi-valued solution S to be rationalized in the following sense: there exists a complete asymmetric relation T (a tournament) such that, for each feasible (finite) set, the solution set of S coincides with the minimal covering set of T restricted to that feasible set. Our characterization result relies only on properties relating S across feasible choice sets. 相似文献

Most political and economic theorists point to moral hazard in teams as the main obstacle to lobbies’ collective action. In
this paper, we address this important issue with a coalition-formation game. In the process of doing so, we characterize equilibrium
lobby structures both in the absence and in the presence of moral hazard. Three notable results emerge from such an exercise:
(1) an equilibrium lobby structure exists under both specifications of the model, (2) moral hazard in teams may raise large
groups’ equilibrium lobby size, and (3) it may also raise the level of collective action of large groups with low organizational
costs.

Transnational social networks powerfully shape Mexican migration and enable families to stretch internationally. In an atmosphere
of such high dependence on social networks, it would be rare for families not to be affected by the opinions of others. This
article analyzes this often-overlooked aspect of social networks, gossip. I analyze gossip stories prevalent for one type
of migrant family, those in which parents and children live apart. Drawing on over 150 ethnographic interviews and observation
with members of Mexican transnational families and their neighbors in multiple sites, I describe both parents’ and children’s
experiences with transnational gossip. I show that in a transnational context, gossip is a highly gendered activity with different
consequences for men and women. Although targeting both women and men, transnational gossip reinforces the expectations that
mothers be family caregivers and fathers be family providers even when physical separation makes these activities difficult
to accomplish.
Joanna Dreby is Assistant Professor of Sociology at Kent State University. Her research focuses on the consequences contemporary migration patterns have for family relationships and particularly for children. Current projects include a study of the impact different family migration patterns have on Mexican school children’s educational and migratory aspirations, and research into how U.S. migration affects the way young Mexican children imagine their families and the United States. 相似文献
