The existing literature on marriage and fertility decisions pays little attention to the roles played by risk preferences and uncertainty. However given uncertainty regarding the availability of suitable marriage partners, the ability to contracept, and the ability to conceive, women's risk preferences might be expected to play an important role in marriage and fertility timing decisions. By using data from the Panel Study of Income Dynamics (PSID), I find that measured risk preferences have a significant effect on the timing of both marriage and fertility. Highly risk-tolerant women are more likely to delay marriage, consistent with either a search model of marriage or a risk-pooling explanation. In addition, risk preferences affect fertility timing in a way that differs by marital status and education, and that varies over the life cycle. Greater tolerance for risk leads to earlier births at young ages, consistent with these women being less likely to contracept effectively. In addition, as the subgroup of college-educated, unmarried women nears the end of their fertile periods, highly risk-tolerant women are likely to delay childbearing relative to their more risk-averse counterparts and are therefore less likely to become mothers. These findings may have broader implications for both individual and societal well-being. 相似文献

Healthy life expectancies are almost always calculated by using health data from cross-sectional surveys. This type of calculation is done partly because data from longitudinal surveys are not always available, and when they are available, they are collected at intervals that are longer than one year. In such cases, collecting health information retrospectively for the years skipped by the survey is useful. The main purpose of this paper is to show how retrospective health information can be used to estimate life expectancies in different health states. Healthy life expectancies are estimated with and without using data on retrospective health information, and the corresponding estimates are compared. The two sets of estimates are similar. We conclude that retrospectively assessed health information based on a one-year recall period can be used to estimate years of life in various health states and that estimates based on such information will closely approximate estimates based on concurrent health information. 相似文献

Indian society suffers from substantial inequalities in education, employment, and income based on caste and ethnicity. Compensatory or positive discrimination policies reserve 15% of the seats in institutions of higher education and state and central government jobs for people of the lowest caste, the Scheduled Caste; 7.5% of the seats are reserved for the Scheduled Tribe. These programs have been strengthened by improved enforcement and increased funding in the 1990s. This positive discrimination has also generated popular backlash and on-the-ground sabotage of the programs. This paper examines the changes in educational attainment between various social groups for a period of nearly 20 years to see whether educational inequalities have declined over time. We use data from a large national sample survey of over 100,000 households for each of the four survey years--1983, 1987-1988, 1993-1994, and 1999-2000--and focus on the educational attainment of children and young adults aged 6-29. Our results show a declining gap between dalits, adivasis, and others in the odds of completing primary school. Such improvement is not seen for Muslims, a minority group that does not benefit from affirmative action. We find little improvement in inequality at the college level. Further, we do not find evidence that upper-income groups, the so-called creamy layer of dalits and adivasis, disproportionately benefit from the affirmative action programs at the expense of their lower-income counterparts. 相似文献

Moving and union dissolution 总被引:1,自引:0,他引:1
This paper examines the effect of migration and residential mobility on union dissolution among married and cohabiting couples. Moving is a stressful life event, and a large, multidisciplinary literature has shown that family migration often benefits one partner (usually the man) more than the other Even so, no study to date has examined the possible impact of within-nation geographical mobility on union dissolution. We base our longitudinal analysis on retrospective event-history data from Austria. Our results show that couples who move frequently have a significantly higher risk of union dissolution, and we suggest a variety of mechanisms that may explain this. 相似文献

In this article we evaluate to what extent between-country differences in the probability of being ‘multidimensional’ poor
can be explained by a range of ‘domain-specific’ indicators of welfare regime arrangements. To this end, a so-called micro-macro
model is estimated, testing the ‘independent’ effect of institutions, as opposed to alternative explanations such as between-country
differences in population composition and economic affluence. Although we conclude that institutional arrangements do influence
the risk of multidimensional poverty in the expected direction, we also find that bringing the ‘economy’ back into the analyses
has a non-trivial impact. Our results point at several avenues for further discussion and research. First, although the more
elaborate welfare regimes generally do a better job in preventing poverty, the level of transfers is not always ‘proportional’
to the general standard of living in these countries. Second, we only find partial confirmation for the often cited ‘negative’
impact of labour market flexibility and the related equality-jobs trade-off. While stricter employment regulations do reduce the poverty risk (be it only after controlling for economic affluence),
flexibility in terms of the availability of fixed-term labour seems to be preferable to unemployment, even if at the individual
level, labour market flexibility increases the likelihood of being poor quite severely.

This paper examines the nonmarket interactions among migrants in the urban labor market of Bangkok, Thailand. We test whether
the population size and the labor-market performance of previous migrants have externalities to new migrants who have moved
from the same province of origin. Our empirical results, which control origin fixed effects, time fixed effects, and origin-
and year-specific correlated shocks, show that (1) the relative population size of previous migrants in the market decreases
the employment probability of new migrants (substitution effect), (2) the employment probability of previous migrants increases
that of new migrants (positive externalities), and (3) when the employment probability of previous migrants is high, however,
the scale effect becomes positive, which demonstrates a threshold in the informational scale economies. The results imply
that positive informational scale effect dominates negative substitution effect when the efficiency of previous migrants is
sufficiently high in the destination labor market.

Talk and ‘telling’ have assumed prominent roles in preventing HIV and promoting life with the disease at the start of the
twenty-first century. Our concern in this paper is to show how social structures and circumstances shape the narrative productions
of HIV positive patients whose lives are institutionally managed. We consider what ‘telling’ means when young women with few
economic resources are encouraged or mandated to talk about themselves by case managers, researchers, therapists, welfare
workers, and clinic staff. We organize our analysis around three such ‘autobiographical occasions’: disclosures to intimate
partners prompted by agents of the state; employment opportunities in which women are hired to tell others about living with
HIV as peer educators or outreach health workers; and research interviews. We argue that storylines about living with HIV
have been laid down by powerful social actors whose illness experiences do not reflect those of many poor patients. These
formulations constitute an ‘archive’ which organizes institutional practices and discourses. These matter not only because
they provide patients with a language through which to render their actions meaningful, but because they shape the everyday
experience of HIV outside the clinic, the welfare office, and the therapy session.

The present research examined whether the observation of emotional expressions rapidly induces congruent emotional experiences
and facial responses in observers under strong test conditions. Specifically, participants rated their emotional reactions
after (a) single, brief exposures of (b) a range of human emotional facial expressions that included (c) a neutral face comparison
using a procedure designed to (d) minimize potential experimental demand. Even with these strong test conditions in place,
participants reported discrete expression-congruent changes in emotional experience. Participants’ Corrugator supercilii facial muscle activity immediately following the presentation of an emotional expression appeared to reflect expressive congruence
with the observed expression and a response indicative of the amount of cognitive load necessary to interpret the observed
expression. The complexity of the C. supercilii response suggests caution in using facial muscle activity as a nonverbal measure of emotional contagion.

Age and Gender Differences in Decoding Basic and Non-basic Facial Expressions in Late Childhood and Early Adolescence 总被引:1,自引:1,他引:0
This study examined age and gender differences in decoding nonverbal cues in a school population of 606 (pre)adolescents (9–15 years).
The focus was on differences in the perceived intensity of several emotions in both basic and non-basic facial expressions.
Age differences were found in decoding low intensity and ambiguous faces, but not in basic expressions. Older adolescents
indicated more negative meaning in these more subtle and complex facial cues. Girls attributed more anger to both basic and
non-basic facial expressions and showed a general negative bias in decoding non-basic facial expressions compared to boys.
Findings are interpreted in the light of the development of emotion regulation and the importance for developing relationships.

This study investigates perceptions of workplace discrimination among racial minorities in Canada. Specifically, the study
examines how objective experiences of disadvantage and expectations for equity influence racial minorities’ perceptions of
discrimination. The results indicate that while both of these factors affect perceptions of discrimination, expectations for
equity may be especially important. Although new immigrants are among the most disadvantaged groups in the Canadian labor
market, they are less likely to perceive discrimination than longer term immigrants, who may have higher expectations for
equitable treatment. Education also increases the perception of discrimination among immigrants, perhaps due to the higher
expectations of educated immigrants. Lastly, objective income inequity is not found to be related to perceived discrimination.
