It has been demonstrated for many pre-industrial populations that the age at marriage, or marriage duration, influences age-specific marital fertility but the reason for this remains unclear. Among the several mechanisms that may be responsible, the following are often cited: secondary sterility or increased subfecundity associated with parity; declining coital frequency; the age difference between the spouses; and, importantly, parity-dependent fertility control. If the latter mechanism were partly responsible for the marriage-duration effect in pre-transition populations, it would contradict the concept of the modern fertility transition as the evolution (or revolution) from parity-independent to parity-dependent fertility. The study presented in this paper investigates the relative importance of these alternative explanations. The application of multivariate Poisson regression to the fertility data from two birth cohorts in the Belgian city of Leuven shows that a linearly declining or even concave age-specific fertility pattern, disaggregated by age at marriage, does not imply parity-dependent fertility limitation.  相似文献

Following a comprehensive evaluation of the health risks of radon, the U.S. National Research Council (US-NRC) concluded that the radon inside the homes of U.S. residents is an important cause of lung cancer. To assess lung cancer risks associated with radon exposure in Canadian homes, we apply the new (US-NRC) techniques, tailoring assumptions to the Canadian context. A two-dimensional uncertainty analysis is used to provide both population-based (population attributable risk, PAR; excess lifetime risk ratio, ELRR; and life-years lost, LYL) and individual-based (ELRR and LYL) estimates. Our primary results obtained for the Canadian population reveal mean estimates for ELRR, PAR, and LYL are 0.08, 8%, and 0.10 years, respectively. Results are also available and stratified by smoking status (ever versus never). Conveniently, the three indices (ELRR, PAR, and LYL) reveal similar output uncertainty (geometric standard deviation, GSD approximately 1.3), and in the case of ELRR and LYL, comparable variability and uncertainty combined (GSD approximately 4.2). Simplifying relationships are identified between ELRR, LYL, PAR, and the age-specific excess rate ratio (ERR), which suggest a way to scale results from one population to another. This insight is applied in scaling our baseline results to obtain gender-specific estimates, as well as in simplifying and illuminating sensitivity analysis.  相似文献

Using conjoint analysis the sensitivity for the four most important retail attributes: price, quality, assortment and locational convinience for food stores is measured for a sample of 400 consumers in Tilburg, The Netherlands. In a second wave the actual shopping behavior is measured using a self-administrated questionnaire. The sensitivity scores are used separately and in conjunction, as sensitivity patterns, to explain patterns of shopping behavior as well as separate shopping characteristics. The relationships found, suggest the usefulness of this kind of approach as it gives in-depth insight into shopping behavior and choice of grocery store.  相似文献

This article examines recent trends in nonmarital cohabitation in the Nordic countries. The data from the Nordic countries suggest that nonmarital cohabitation has moved from being a deviant phenomenon to an institutionalized pattern of entering family life.  相似文献

Money, power and inequality within marriage   总被引:4,自引:1,他引:3  
The growing body of research on the intra-household economy suggests that in couple households there are significant associations between control over household finances and more general power within the household. However, most earlier research has been based on relatively small samples. Here a major new British data set, produced by the Social Change and Economic Life Initiative, is used to examine the relations between money, power and inequality within marriage. Six different systems of financial allocation are identified. The results suggest that even when couples nominally pool their money, in practice either husband or wife is likely to control the pool. In only one fifth of couples was the pool jointly controlled, but these households were characterised by the highest levels of equality between husband and wife in terms of decision making, experience of deprivation and access to personal spending money. Findings from the study indicate a complex pattern of relationships between household income level, household allocative system and gender. Female control of finances, though it was associated with greater decision-making power for women, did not protect them against financial deprivation; however, male control of finances, especially when it took the form of the housekeeping allowance, did serve to protect the financial interests of men in comparison with women. Gender inequality was least in households with joint control of pooled money and greatest either in low income households or in higher income households with male control of finances.  相似文献

The economic consequences of business closings and worker layoffs are of great concern to today's work force. The study compares earnings of 755 workers previous to displacement to 422 displaced workers with new earnings. Variables are identified using the data supplement of the 1988Current Populations Survey: Displaced Workers. Displaced workers employed in professional and white-collar positions have more favorable predisplacement earnings and new earnings than workers from other job sectors, but displaced workers who are homeowners and those who have health care coverage before and following job displacement have a decline in earnings. Displaced workers with some high school education and workers with 30 to 39 years of job tenure also experience decreased wages. Overall, displacement of American workers stifles the economy and negatively influences the human capital of the nation's work force. Her major research interests include displaced worker issues, work and family policy, and the economics of aging. Her major research interests include labor force participation of midlife and older persons.  相似文献
