Subjective utility and plans for childbearing and employment

Nonrecursive models of plans for childbearing and employment were estimated for a sample of white married women, age 26 to 36, with one or two young children. Women's concerns about care of children already born did inhibit their employment plans. Further, plans to have another child in the near future had a direct negative effect on full-time employment plans among women with one child, but not among women with two children. No direct effects of childbearing plans on part-time employment plans were found. In contrast to earlier research on longterm childbearing and employment plans, no direct effects of employment plans on plans for childbearing were found. It is suggested that attainment of the two-child family marks a turning point in the relation between childbearing and wives' employment.This research was partially supported by grants from the Center for Population Research, NICHD to Battelle Human Affairs Research Centers, Seattle, Washington (1-R01-HD10683), and to the Center for Demography and Ecology, University of Wisconsin, Madison (1-R01-HD05876).

Unemployment and marital dissolution

This paper analyses the effects of unemployment on the probability of marital dissolution. Based on panel data for a sample of Danish married couples, we estimate a dynamic model for the probability of marital dissolution where we take into account the possible effects of unemployment for both spouses. We also control for other factors such as education, age, presence of children, place of residence, health and economic factors. The empirical results show that unemployment seems to be an important factor behind marital instability. However, only unemployment of the husband has an effect, and this effect is immediate.We thank two anonymous referees for their helpful comments on an earlier draft.

Long- and short-term affective states in happiness: Model,paradigm and experimental evidence

The present paper evaluates relevant findings on long- and short-term affective states in subjective well-being and argues for a componential model that combines the two into the more general concept of happiness. Two age parameters, one for long-term and one for short-term affect are added to the simple model to account for age changes in happiness. Measures of long- and short-term affect are presented, as is a paradigm for separating the components. Support for the simple model is provided by an experimental investigation with 64 college students who were exposed to positive and/or negative mood induction. As expected, the induction had substantially greater effect on short- than on long-term affect measures, particularly the negative induction procedure. These findings are consistent with predictions. However, multiple age cohorts will have to be assessed within a longitudinal framework to obtain values for the age parameters.     

The ecology of race and socioeconomic distress: infant and working-age mortality in Chicago

We examine the effects of education, unemployment, and racial segregation on age-, sex-, and race-specific mortality rates in racially defined Chicago community areas from 1989 to 1991. Community socioeconomic factors account for large observed areal variations in infant and working-age mortality, but especially working-age mortality for the black population. For black men, the mortality consequences of living in economically distressed communities are quite severe. Segregation effects on mortality are more modest and largely operate through neighborhood socioeconomic conditions, although some direct effects of segregation on mortality for blacks are apparent.     

Gender and the Stability of Same-Sex and Different-Sex Relationships Among Young Adults

Most research on the stability of adult relationships has focused on coresidential (cohabiting or married) unions and estimates rates of dissolution for the period of coresidence. Studies examining how the stability of coresidential unions differs by sex composition have typically found that same-sex female couples have higher rates of dissolution than same-sex male couples and different-sex couples. We argue that the more elevated rates of dissolution for same-sex female couples are a by-product of the focus on coresidential unions. We use data from the National Longitudinal Study of Adolescent to Adult Health to compare rates of dissolution based on the total duration of romantic and sexual relationships for same-sex male couples, same-sex female couples, and different-sex couples. Results from hazard models that track the stability of young adult relationships from the time they are formed demonstrate that male couples have substantially higher dissolution rates than female couples and different-sex couples. Results based on models restricted to the period of coresidence corroborate the counterintuitive finding from earlier studies that female couples have the highest rates of dissolving coresidential unions. This study underlines the importance of comparisons between these couple types for a better understanding of the role that institutions and gender play in the stability of contemporary relationships.     

Time use in child care and housework and the total cost of children

The use of time for child care and housework among Swedish families is investigated. We allow the effect of children on child care and housework to vary by age of the child and also by whether the child is cared for outside the home or not. Our estimates allow us to compute the total cost of children in the form of the cost of time, and the cost of goods, services and housing.The result shows that time used for child care decreases sharply with the age of the child but this is not the case for time used for other housework. Considerable economies of scale is found to prevail for time used for child care. Child care outside the home reduces time use for other housework but the effect on time used for child care is quite small. For the average family time use cost make up more than half of total child cost. Our estimates indicate that decreased time use cost for children caused by care outside the home are not very different from a typical parental fee for public day care.This research was supported by a grant from the Swedish Council of Social Research (SFR).

Time use and leisure: Subjective and objective aspects

This paper utilizes data from the 1981 Canadian Time Use Pilot Study and from a small Halifax time-budget study to look at subjective and contextual dimensions of leisure for women and men. The Canadian study (n=2685) had information on the time spent in daily activities as well as on the settings and social contexts of those activities. The Halifax study included similar time-budget information on 60 married couples, but also incorporated subjective ratings of all diary events in terms of perceived work or leisure. Using subjective weightings from the Halifax study, estimates of subjective leisure were made for different categories of daily activity and for different Canadian population subgroups. Hypercodes were used to look at the effect of social roles on leisure time, and the AID procedure was used to analyze the contextual dimensions of leisure for men and women. The results show that objective activity and well as subjective leisure vary by population subgroup. Constraints to leisure include being female, being employed, having children, and, to some degree, being married. Of the contextual dimensions, subjective leisure was shown to be influenced primarily by type of objective activity. Location, time of day and day of the week also influenced leisure designations, but to a lesser extent. This study suggests the potential usefulness of subjective weightings of activities in order to gain a greater understanding of leisure patterns and participation.     

Aging mothers and aging daughters: life-long caring and intellectual disability

While aging and caring are well-discussed in academic literature, the association among aging, caring and intellectual disability is less well documented. This paper draws on a recently completed Australian study which focuses on such mother/daughter relationships and whose narratives form the framework for an argument for a re-imagining of the concept of care for aged people with intellectual disability. Specifically, using a genealogical approach, the paper describes how powerful discourses at the time of the daughter's birth (1940s and 1950s)--associated with eugenics, institutional care and motherhood--are framing the way in which aging mothers are now contemplating the future care for their adult (and also aging) daughters.     

Political History and Disparities in Safe Motherhood Between Guatemala and Honduras

Each year, worldwide, more than 500,000 women die of complications from childbirth, making this a leading cause of death globally for adult women of reproductive age. Nearly all studies that have sought to explain the persistence of high maternal mortality levels have focused on the supply of and demand for particular health services. We argue that inquiry on health services is useful but insufficient. Robust explanations for safe motherhood outcomes require examination of factors lying deeper in the causal chain. We compare the cases of Guatemala and Honduras to examine historical and structural influences on maternal mortality. Despite being a poorer country than Guatemala, Honduras has a superior safe motherhood record. We argue that four historical and structural factors stand behind this difference: Honduras's relatively stable and Guatemala's turbulent modern political history; the presence of a marginalized indigenous population in Guatemala, but not in Honduras, that the state has had difficulty reaching; a conservative Catholic Church that has played a larger role in Guatemala than Honduras in blocking priority for reproductive health; and more effective advocacy for maternal mortality reduction in Honduras than Guatemala in the face of this opposition.     

Demography and the environment

Demographers' interest in the environment has generally been enmeshed in broader issues of population growth and economic development. Empirical research by demographers on environmental issues other than natural-resource constraints is limited. In this paper, I briefly review past demographic thinking about population and the environment and suggest reasons for the limited scope of demographic research in this area. Next, I describe more recent demographic research on the environment and suggest several newer areas for demographic research. Finally, I consider the future of research on the environment in the field of demography.     

Welfare states and social inequality: Key issues in contemporary cross-national research on social stratification and mobility

Research on welfare states and research on social stratification and mobility share a common concern for social inequality. Research on welfare states is usually comparatively designed, looking for similarities and variation across countries in a number of aspects related to social structure and social institutions. On the other hand, the basic model of social stratification, utilized in most cross-national research on social stratification and mobility, is an abstract model which does not specify why and how we are to understand cross-national differences. Yet for about 20 years or so, researchers within the social stratification community have undertaken several cross-national studies. This paper reviews a few selected studies within each area and summarizes their conclusions with regard to similarities versus differences between countries. In the final section of the paper, I discuss key issues for future work within cross-national research on social stratification.     

Marital Sorting and Parental Wealth

The extent of marital sorting by socioeconomic background has implications for the intergenerational transmission of inequality, the role of marriage as a mechanism for social mobility, and the extent of cross-group interactions within a society. However, studies of assortative mating have disproportionately focused on spouses’ education, rather than their social origins. Using data from the Panel Study of Income Dynamics (PSID), and exploiting the unique genealogical design of the data set, we study the degree to which spouses sort on the basis of parental wealth. We find that the estimated correlation in parental wealth among married spouses, after controlling for race and age, is about .4. Importantly, we show that controlling for spousal education explains only one-quarter of sorting based on parental wealth. We show that our results are robust to accounting for measurement error in spousal reports of parental wealth and for selection into and out of marriage.     

Welfare states and inequality: Institutional designs and distributive outcome

Comparative studies on inequality have suffered from severe methodological problems, which mean that issues related to the causes of cross-national variation in inequality remain unresolved. In comparative welfare state research, the preoccupation with expenditure data has also meant that the welfare state itself has remained a black box. By examining new comparative data on social policy institutions and income inequality among different population groups, this study provides a more precise empirical basis for evaluating different, and divergent, theories on the welfare state and equality. Three cases will be used as illustrations: family policy and child poverty, unemployment benefits and poverty among working aged, and old-age pensions and poverty among the elderly. The results suggest that the key for understanding the effect of the welfare state lies in the institutional design—in the level and distribution of social rights. The importance of the welfare state for social stratification deserves to be given more attention by sociological research in the future.     

Determinants of short- and long-term mobility expectations for home owners and renters

Confusion about the role of residential satisfaction vis-à-vis structural factors in the mobility process stems from the failure to examine the determinants of mobility over varying time frames and housing tenures. Using survey data for a random sample of 580 Phoenix-area households, we test models of short-term (1 year) and long-term (5 years) mobility expectations for home owners and renters. The results show that residential satisfaction mediates the effects of structural variables on mobility expectations in the short term for home owners. In the long-term model for home owners and the short-term model for renters, the role of satisfaction as an intervening force declines in relative importance. Among renters, structural variables operate directly on long-term mobility expectations.     

Beliefs and values and the sterilization decision

A decision-making framework based on the models of personal decision making developed by psychologists and economists and a methodology based on axiomatic conjoint measurement are used to explore individuals' beliefs and values regarding contraceptive sterilization. Particular emphasis is given to demonstrating a. that there exist individual differences in beliefs and values, b. that there exist differences in beliefs and values between persons who choose sterilization—either tubal ligation or vasectomy—and persons who choose non-sterilization contraceptive methods when no more children are wanted, and c. that the effect of beliefs and values on the sterilization decision is an interactive one. The methodology used is compared to that typically used in studying fertility- and health-related behaviors.This research was supported by grants HD-10802 and HD-14403 from the National Institute of Child Health and Human Development.

Models and Proposals for Malaria: A Review

Mathematical models to study the dynamics of malaria continue to be developed and upgraded on the parasite component, which is the causative agent for malaria; on the human component that serves as a reservoir of infection for the blood feeding female mosquitoes; on the disease transmitting vector, the component mostly responsible for the movement of the parasite agent from one human to another; or on the life cycle of the malaria parasite as a pathogen both within the human and vector populations. The consideration of so-far neglected features can be beneficial for the control of malaria.     

Skeletal biology and the history of Native Americans and African Americans

The authors incorporate data from skeletal remains in an attempt to construct health profiles for the Amerindian population before Columbus's arrival and for the antebellum black slave populations of North America and the Caribbean. They examine the impact of poor nutrition among slaves, as evidenced in bone and tooth samples, on infant and childhood mortality, fertility, and adult mortality. They go on to suggest that the change from a hunter-gatherer life-style to a more sedentary agricultural one resulted in poorer health for the Amerindian population. However, agriculture made soft foods more available, allowing women to wean their children earlier, thus increasing overall fertility.     

Home Ownership and Job Satisfaction

This paper investigates the link between job satisfaction and home ownership. We explicitly focus on the effect of a transition from non-ownership to ownership on the self-reported job satisfaction scores. In other words, we concentrate on the change in job satisfaction response for individuals observed right before and after the transition. Utilizing the panel feature of the British Household Panel Survey, we find that transition to ownership reduces job satisfaction within a year following the purchase—controlling for observed variation and unobserved heterogeneity. The reduction in job satisfaction is sharper when the purchase is financed through a mortgage. We also test if this pattern persists over years. We show that the initial reduction in job satisfaction is more than doubled within 3 years after the transition for both categories of ownership. We conclude that home ownership may be a constraint for the career prospects of the employed workers, since it reduces mobility and forces them to become more dependent on the local labor market conditions. These concerns are deeper in case of a debt-financed ownership.
