Researchers from a number of disciplines have offered competing theories about the effects oJ childbearing on parents 'postreproductive longevity. The "disposable soma theory" argues that investments in somatic maintenance increase longevity but reduce childbearing. "Maternal depletion" models suggest that the rigors of childrearing increase mortality in later years. Other researchers consider continued childbearing a sign of healthy aging and a predictor of future longevity. Empirical studies have produced inconsistent and contradictory results. Our focus is on the experience of widowhood, which has been ignored in previous studies. We hypothesize that the death of a spouse is a stressful event with long-term consequences for health, especially for women with small children. Data are drawn from historical sources in Sweden, Belgium, and the Netherlands from 1766 to 1980. Postreproductive mortality was highest among young widows with larger families in all three samples. Age at last birth had little or no effect. We conclude that raising children under adverse circumstances can have long-lasting, harmful effects on a mother's health. 相似文献

Using the first (1995) and third (2001-2002) waves of the Add Health survey, we examine women 's family transitions up to age 24. Only a third of all women marry, and a fifth of those marriages dissolve before age 24. Three out of eight women have afirst birth, with a substantial majority of those births outside of marriage: 66% for whites, 96% for blacks, and 72% for Mexican Americans. Cohabitation is the predominant union form; 59% of women cohabit at least once by age 24. Most cohabitations are short lived, with approximately one in five resulting in a marriage. We summarize the family and relationship experience of women up to age 24 in terms offour categories, each accounting for roughly a quarter of all women. Category 1 has the women who remain single nonparents. Category 2 has the early marriers, women whose marriage is not preceded by a first birth. Category 3 has those who become single parents. Category 4 has the women who cohabit at least once, but who do not marry or have a birth by age 24. The strictly ordered transitions of the 1950s are long gone and have been replaced by a variety of paths to adulthood. 相似文献

Whereas period life expectancy constitutes an intuitive indicator of the survival conditions prevailing at a particular period,
this paper argues that, given the existence of welfare interdependencies, that widespread indicator is nonetheless an incomplete
measure of the longevity achievements relevant for human well-being. The central importance of coexistence for human-beings
implies that usual life expectancy measures should be complemented by joint life expectancy indicators, which measure the
average coexistence time under particular survival conditions. After a study of the theoretical foundations of ‘single’ and
‘joint’ life expectancy indicators, it is shown that joint life expectancy measures tend to enrich significantly the comparison
of longevity achievements across countries and periods. Moreover, the introduction of joint life expectancy indicators—as
a complement to conventional life expectancy measures—into multi-variable indexes such as the United Nations’ HDI is also
shown to affect international rankings of standards of living to a non negligible extent.

Are there gender and country of origin differences in immigrant labor market outcomes across European destinations? 总被引:2,自引:0,他引:2
The 1994–2000 waves of the European Community Household Panel are used to study the earnings of immigrants as compared to
native workers in 15 European countries. At the time of arrival, there is a significant negative partial effect of foreign
birth on individual earnings compared to the native born in the destination of around 40%. These differences vary across origins
and destinations and by gender. Immigrant earnings catch-up to those of the native born after around 18 years in the destination.
Schooling matters more for earnings for women, whereas, language skills are relatively more important for men.

Black is not always black. Subtle distinctions in skin tone translate into significant differences in outcomes. Data on more
than 15,000 households interviewed during the 1860 US federal census exhibit sharp differences in wealth holdings between
white, mulatto, and black households in the urban South. We document these differences, investigate relationships between
wealth and recorded household characteristics, and decompose the wealth gaps to examine the returns to racial characteristics.
The analysis reveals a distinct racial hierarchy. Black wealth was only 20% of white wealth, but mulattoes held nearly 50%
of whites’ wealth. This advantage is consistent with colourism, the favouritism shown to those of lighter complexion.

This paper investigates changing attitudes towards the euro over time in Germany using longitudinal micro-data from the German
Socio Economic Panel Study. We observe that a large part of the German population was worried about the new currency both
before and after its introduction. Social psychological theories provide insight into these attitudes. Concerns regarding
the euro are apparently connected with problems in handling the new currency and with the press coverage of price rises. For
these reasons, future EMU member states should prepare their populations better for these challenges. 相似文献
