The impact of SES on mortality is an established fact. I examine if this impact decreases with increasing age. Most research finds that it does so but it is unknown whether this decrease is due to mortality selection. The data I use come from the US-Health and Retirement Study, which surveyed...

In our study we investigate interdependencies between entry into a marital union, childbirth, and migration. We apply event-history techniques to retrospective data on women aged 18-29 from a survey conducted in northern Kyrgyzstan in 2005 to examine how these events can influence one another,...

This goal of this study is to add to our understanding of the impact of women’s human capital accumulation on the timing of first births. Applying intensity regression to national retrospective data, we examined the transition to motherhood in Italy and Poland. These countries share several...

Hamilton quantified the force of selection on an age-specific mutation. Hamilton’s indicators of the age-specific force of selection always decline with age. This result is of profound importance to the theory of the evolution of senescence. Here I derive alternative indicators within...

The aim of this paper is to compare family policies and fertility patterns in the former German Democratic Republic (GDR) and the German Federal Republic (FRG). Among other aspects, both societies particularly differed in the integration of women into the labor market. By contrasting the...

Simple series systems of identical components with spare parts are considered. It is shown that the cumulative distribution function of a system failure time tends to a step function as the number of components increases and resources can be shared. An example of ‘continuous resources’ is...

Using retrospective union, birth, and education histories that span 1980-2003, this study investigates nonmarital childbearing in post-Soviet Russia. We employ a combination of methods to decompose fertility rates by union status and analyze the processes that lead to a nonmarital birth. We find...

The relationship between increasing women’s earnings and rising divorce rates frequently has been explained by the so-called independence effect: If a wife enjoys a higher earning than her husband does, she gains less from marriage. It has also been argued that in a society with egalitarian...
