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

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

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

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

We use data from the Fragile Families and Child Wellbeing Study to investigate the association between coparenting quality and nonresident fathers' involvement with children over the first five years after a nonmarital birth. We find that about one year after a nonmarital birth, 48% of fathers are living away from their child, rising to 56% and then to 63% at three and five years, respectively Using structural equation models to estimate cross-lagged effects, we find that positive coparenting is a strong predictor of nonresident fathers' future involvement, whereas fathers' involvement is only a weak (but significant) predictor of future coparenting quality. The positive effect of coparenting quality on fathers' involvement is robust across several techniques designed to address unobserved heterogeneity and across different strategies for handling missing data. We conclude that parents' ability to work together in rearing their common child across households helps keep nonresident fathers connected to their children and that programs aimed at improving parents' ability to communicate may have benefits for children irrespective of whether the parents' romantic relationship remains intact. 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

The effect of education on health has been increasing over the past several decades. We hypothesize that this increasing disparity
is related to health-related technical progress: more-educated people are the first to take advantage of technological advances
that improve health. We test this hypothesis using data on disease-specific mortality rates for 1980 and 1990, and cancer
registry data for 1973–1993. We estimate education gradients in mortality using compulsory schooling as a measure of education.
We then relate these gradients to two measures of health-related innovation: the number of active drug ingredients available
to treat a disease, and the rate of change in mortality from that disease. We find that more-educated individuals have a greater
survival advantage in those diseases for which there has been more health-related technological progress. 相似文献

The objectives of the study are threefold: (1) to provide estimates of the total populations and spatial distributions of
different language groups in Turkey, (2) to test whether the commonly held belief that Turkish-speaking and Kurdish-speaking
populations are “actors” of different demographic regimes is true, and (3) to assess whether a process of integration, in
the form of intermarriage of Turks and Kurds is under way in Turkey. Data come mainly from the 2003 Turkish Demographic and
Health Survey (TDHS-2003). Based on the assumption that the mother tongue composition of women is also representative of that
of the whole population, the results of the TDHS-2003 imply that of the population of Turkey, 83% are Turkish-speaking, 14%
are Kurdish-speaking, 2% are Arabic-speaking and the remaining 1% belong to other language groups. Results show that despite
intensive internal migration movements in the last 50 years, strong demographic differentials exist between Turkish and Kurdish-speaking
populations, and that the convergence of the two groups does not appear to be a process under way. Turks and Kurds do indeed
appear to be actors of different demographic regimes, at different stages of demographic and health transition processes. 相似文献
