We estimate the effect of family size on various measures of labor market outcomes over the whole career until retirement, using instrumental variables estimation in data from Norwegian administrative registers. Parents’ number of children is instrumented with the sex mix of their first two children. We find that having additional children causes sizable reductions in labor supply for women, which fade as children mature and even turn positive for women without a college degree. Among women with a college degree, there is evidence of persistent and even increasing career penalties of family size. Having additional children reduces these women’s probability of being employed by higher-paying firms, their earnings rank within the employing firm, and their probability of being the top earner at the workplace. Some of the career effects persist long after labor supply is restored. We find no effect of family size on any of men’s labor market outcomes in either the short or long run.  相似文献

Fisher information contained in record values, inter-record times and their concomitants from a sample of fixed size is derived in general and explicit expressions are deduced for some specific known bivariate classes of distributions. A comparison between fixed sampling and inverse sampling schemes with equal number of records and concomitants is also carried out. We also consider parameter estimation based on bivariate records and a small simulation study is done.  相似文献

Conditional parametric bootstrapping is defined as the samples obtained by performing the simulations in such a way that the estimator is kept constant and equal to the estimate obtained from the data. Order statistics of the bootstrap replicates of the parameter chosen in each simulation provide exact confidence intervals, in a probabilistic sense, in models with one parameter under quite general conditions. The method is still exact in the case of nuisance parameters when these are location and scale parameters, and the bootstrapping is based on keeping the maximum-likelihood estimates constant. The method is also exact if there exists a sufficient statistic for the nuisance parameters and if the simulations are performed conditioning on this statistic. The technique may also be used to construct prediction intervals. These are generally not exact, but are likely to be good approximations.  相似文献

“Fortigenesis” (L. fortis=strong) refers to a process of developing strengths at a variety of endpoints. Assumptions are: (i) there exist 2 continua, of mental illness and mental health, along which waxing and waning in the process of fortigenesis moves individuals in the directions of more or less strength; (ii) challenge, struggling and suffering, due to inordinate demands, are inherent to the human condition; (iii) there are strengths to negotiate and resile these demands, and even to harness them towards subsequent flourishing; and (iv) there are also purely positive experiences. The background to a “science of strength” is presented briefly. Subjective well-being, questing for meaning, thriving/flourishing, and interpersonal flourishing, are reviewed as illustrative themes. The review is limited to English language and Occidental literature, and to matters mainly apparent in individual adult lives. This article is dedicated to the memory of Josua P.P. Fullard (d. June 30, 2001) who passed the highest test in living magna summa cum laude. Jan Esser, Griffiths Lubisi, Malan Heyns, Aharon Segal, Nic van der Walt (d.

The growing demand for long-term care (LTC) causes the relationship between children and their parents to gain increased importance for society. Parents may create incentives for children to provide LTC through bequests, or they may purchase LTC insurance. While these instruments have been analyzed separately in the literature, this article shows that optimal LTC insurance must be small in the presence of bequests. Thus, the failure of private LTC insurance to diffuse into middle-class households may be explained by the fact that the bequest instrument is fully available to the current generation of parents, who for the first time since 1914 are in a position to bequeath an intact stock of capital in major industrialized countries.  相似文献

Despite the high adoption level of Facebook and other social network sites (SNSs) in Norway, local level voluntary associations have not embraced SNSs to the same degree. Regular websites are the main web representation, and information provision is the main function of the associations’ web representations. Using quantitative data on website content and organizational characteristics we have analyzed which factors hinder SNS adoption. The results point to size and complexity of associations and to age-based digital divides among members as important factors for having a profile on a SNS. It seems that a certain numerical point must be reached in terms of organizational and community size, for SNSs to be useful. Also, older members, smaller economy and a low degree of formalization in associations might hamper the implementation of SNSs in associations. Using Norway as a critical case, this article contributes new knowledge about web communication in voluntary organizations, an increasingly important field of research internationally.  相似文献

This is a longitudinal study assessing language and literacy skills in internationally adopted children and controls at four years and in second grade at school. The results show small differences between the groups on language skills except for language comprehension at the age of four and reading comprehension in second grade where the adoptees scored significantly lower than their peers did. Significant predictors of the reading comprehension in the second grade were impressive vocabulary for the non-adoptees and letter recognition for the adoptees at the age of four, and decoding skills and expressive vocabulary for both groups in second grade.  相似文献

This article, taking as its point of departure that voluntary organizations are of crucial importance in a democracy, views the transformation of the Norwegian voluntary sector through the lenses of what happens within the environmental field. Seeing changes within this field as prototypical for the transformation of the voluntary sector more generally, we start with the organizational level and contrast old versus new environmental organizations. The aim is to ascertain to what extent the newly built organizations are leaving the historically important democratic organizational model. Second, we compare attitudes toward democracy of members of the democratically and nondemocratically built organizations: attitudes both toward democracy within a voluntary organization (internal) and democracy in society (external). Furthermore, we compare these findings with what we find for the population at large. The last section analyzes demographic characteristics of organized environmentalists to see whether a new type of elite, more distanced from the population at large, is emerging in the new and nondemocratically built organizations. The study finds that new organizations are definitely breaking with the democratic organizational model. The support for democracy (internal and external) is comprehensive but not always overwhelming, and there is a tendency in the direction of congruence between organizational structure and individual attitudes. That is, members of democratically built organizations especially value internal but also to some extent external democracy more than members of nondemocratically built organizations. However, even if formal democratic structure and democracy as an absolute and generalized value seems to be under pressure, it does not follow that a new type of elitism is emerging.  相似文献
