Maternal mortality in Mexico: measurement based on vital statistics

"Vital statistics are the most comprehensive source of information on maternal mortality in Mexico.... It is clear that maternal mortality has decreased throughout the twentieth century and will continue to do so. There are signs of a higher underestimation of mortality [due to] abortion. And there are regional differentials of maternal mortality.... Professional and/or institutional attention during childbirth has a great impact on maternal mortality decline. There are also socio-economic differentials by marital status, milieu, and schooling...." (EXCERPT)     

Features of nuptiality in the border zone

"This article is limited to an analysis of some characteristics of nuptiality in the municipalities in the northern border zone of Mexico, based on the classification of the population by age and sex [and] by marital status...contained in the 1980 Census.... Nuptiality in the border zone is not only distinguished from that of the country as a whole, but also in relation to the states in which the municipalities comprising it are located."

Private Schools and the Parents that Choose Them: Empirical Evidence from the Danish School Voucher System

Research on the effect of school choice on student performance has generally been based on small-scale experiments or comparisons of Catholic and public schools in the United States. Recent studies indicate, however, that the market competition stemming from school vouchers does not affect all private schools equally. This study makes use of individual-level register data on the performance of more than 30,000 students in Denmark, where private schools have been voucher-financed for more than 100 years, while public schools are governed and financed by the politico-administrative system. Using an instrumental variable model to exclude selection effects, the results show no significant average effect of private schooling on final examination scores. However, a multilevel model shows that private schools of high socio-economic status perform better than similar public schools, while private schools of low socio-economic status under-perform – even for individual students with high socio-economic status. This indicates that the institutional setting of a voucher system is not enough to raise educational performance in general, arguably because some parents choose schools on the basis of non-academic criteria.     

Trends in mortality differentials and life expectancy for male social security-covered workers, by socioeconomic status

This article presents an analysis of trends in mortality differentials and life expectancy by average relative earnings for male Social Security-covered workers aged 60 or older. Because average relative earnings are measured at the peak of the earnings distribution (ages 45-55), it is assumed that they act as a rough proxy for socioeconomic status. The historical literature reviewed in this analysis generally indicates that mortality differentials by socioeconomic status have not been constant over time. For this study, time trends are examined by observing how mortality differentials by average relative earnings have been changing over 29 years of successive birth cohorts that encompass roughly the first third of the 20th century. Deaths for these birth cohorts are observed at ages 60-89 from 1972 through 2001, encompassing roughly the last third of the 20th century. The large size and long span of death observations allow for disaggregation by age and year-of-birth groups in the estimation of mortality differentials by socioeconomic status. This study finds a difference in both the level and the rate of change in mortality improvement over time by socioeconomic status for male Social Security-covered workers. Average relative earnings (measured as the relative average positive earnings of an individual between ages 45 and 55) are used as a proxy for adult socioeconomic status. In general, for birth cohorts spanning the years 1912-1941 (or deaths spanning the years 1972-2001 at ages 60-89), the top half of the average relative earnings distribution has experienced faster mortality improvement than has the bottom half. Specifically, male Social Security-covered workers born in 1941 who had average relative earnings in the top half of the earnings distribution and who lived to age 60 would be expected to live 5.8 more years than their counterparts in the bottom half. In contrast, among male Social Security-covered workers born in 1912 who survived to age 60, those in the top half of the earnings distribution would be expected to live only 1.2 years more than those in the bottom half. The life expectancy estimates in this article represent one possible outcome under one set of assumptions. These projections should not be regarded as an accurate depiction of the future. Specifically, this study adopts a simple projection method in which differentials are assumed to follow the pattern observed over the last 30 years of the 20th century for the first 30 years of the 21st century. This assumption lacks theoretical underpinnings because the causes of the widening differentials observed over the past 30 years have not been determined. On the one hand, if the trend of widening mortality differentials by year of birth observed over the past 30 years does not continue, the projection method used in this analysis could lead to an overestimation of future differences in life expectancy between socioeconomic groups. On the other hand, if mortality differentials do not narrow by age as observed in the past, the projection method used could lead to an underestimation of the differences in life expectancy between socioeconomic groups aged 60 or older.     

The Who,When, and Where of Executive Nominations: Integrating Agency Independence and Appointee Ideology

In recent years, scholars have expended considerable efforts to understand the executive appointment process and the forces influencing the choices made by the president and the Senate. However, some factors integral to theoretical models have not been well integrated empirically, and other relevant factors have not been incorporated much at all. Here, we focus on one determinant corresponding to the former critique—nominee ideology—and another corresponding to the latter—the independence of decision makers in the targeted agencies. We examine a series of theoretically driven hypotheses regarding the effects of both ideology and independence on who gets nominated and if and when nominees are eventually confirmed. Results show nominee ideology and decision maker independence matter a great deal and factor into presidential strategic choices and senatorial responses in ways according to expectations. Our findings have important ramifications for understanding appointments empirically and for future theoretical development.     

Mortality by cause among children younger than age one in Mexico

"This article presents the levels and trends of deaths among children [in Mexico] under the age of one, by groups of causes, for some states, for the years 1979-1985. Identifying the causes of death according to the international classification of diseases, both for deaths among children under the age of one and for total deaths, the goal is to establish a comparison of the levels of general and infant mortality by groups of causes. The data are taken from the statistical yearbooks of the Head Office for Statistics, for the years 1979 to 1985." (SUMMARY IN ENG)     

Asset holdings of the newly disabled: findings from the New Beneficiary Survey

About 3 out of 4 new disabled-worker beneficiaries or their spouses owned some type of financial asset in 1982, but the median value of these assets was quite small, according to data obtained by the Social Security Administration in its New Beneficiary Survey. A smaller majority reported owning their own homes, and home equity accounted for most of the reported wealth. Barely a tenth reported that they owned farms, businesses, or commercial property. Differences in age and marital status within the newly disabled population were associated with large differences in asset holdings. Married couples and older disabled workers generally were more likely to own each kind of asset, and generally reported higher values for these assets. Older married men--the largest subgroup among the disabled--are also relatively well-off, though their median asset portfolios were worth only +3,600 when home equity was excluded. Younger single men, the third largest subgroup, reported median total assets worth less than +50, however home equity was treated. The asset ownership rates and median values reported by the new disabled-worker beneficiaries are much lower for every type of asset considered than the rates and values reported by a comparable sample of new retired-worker beneficiaries.     

Contraceptive practice and social class in Mexico: recent experience

Data from the 1982 National Demographic Survey are analyzed to study recent changes in contraceptive use and sterilization in Mexico. Variables studied in relation to contraceptive use include method used, place where information was obtained, social class, rural or urban area, age, education, marital status, and place of residence. In relation to sterilization, variables studied include age, social class, institution where sterilization was performed, number of children, and date of birth of last child. (SUMMARY IN ENG)     

The population of a Mexican parish in the eighteenth century: Santa Maria de la Presentation de Chilapa

The author analyzes parish registers and census data for Santa Maria de la Presentacion de Chilapa, Mexico, to determine the characteristics of the parish population during the final quarter of the eighteenth century. He provides estimates of age and sex distribution and marital status, and considers the demographic impact of epidemics and famines brought about by colonization.     

Suicidal intentions and suicides in Mexico, 1977-1984

The author examines and compares levels and trends in suicide in Mexico, using official data for 1977 and 1984. Consideration is given to characteristics of those who attempt or commit suicide, including geographic differences, method preferred, age, marital status, and reasons for wanting to die.     

Volunteer labor sorting across industries

Volunteer labor is generally analyzed as a homogeneous activity, implying that the marginal effects of tax changes and demographic shifts are equal across industries and forms of volunteering. Here the homogeneity assumption is tested by estimating and comparing volunteer labor supply functions in three sectors that rely on volunteer labor—health, education, and religious organizations. Differences in the marginal volunteer labor supply effects are associated with personal demographics, household composition, and tax status. These differences are significant statistically as well as for their policy implications. The effects on volunteering to each sector are predicted for changes in the age, education, and marital status distributions of the population, as well as for changes in income tax rates, itemization status, and income. © 2002 by the Association for Public Policy Analysis and Management.     

Policy analysis through microsimulation: the STATS model

This article gives a nontechnical introduction to a microsimulation model developed by the Social Security Administration to consider the effects of tax and benefit proposals on the economic status of population groups. This model, the Simulated Tax and Transfer System (STATS) model, uses information from a nationally representative survey of households to calculate taxes or benefits for thousands of persons or families, case by case. Then the model aggregates across individual cases to produce estimates for economic and demographic groups of interest to policymakers. Groups are defined by such characteristics as family income, age, sex, and marital status. The article explains the model's microsimulation approach and its emphasis on the economic status of population groups. It describes the procedures for simulating taxes and benefits and then illustrates the use of the model by considering a proposal to change the way Social Security benefits are taxed. The article also discusses the primary data source and the extent to which it limits the types of estimates that the model can produce.     

Women, marriage, and Social Security benefits

The majority of women Social Security beneficiaries receive at least part of their benefit based on their status as the wives or widows of entitled workers. This article discusses the impact of past and present marital status of women as a factor in establishing eligibility for monthly benefits and the amount of the benefit payment. The data are drawn from the 1980 and 1985 June Marital History Supplements to the Current Population Survey. Whether or not they are currently receiving auxiliary benefits, most older women are potentially eligible for them based on their current marital status or past marital duration.     

The evolution of mortality in Mexico, 1940-1980

The author analyzes mortality trends in Mexico in the twentieth century, particularly since 1940. Trends are examined according to age, sex, and cause of death. The decline in mortality is then considered in the context of the country's history and other mortality transitions. Regional variations and excess mortality are also described.

The Social and Productive Impacts of Zambia's Child Grant

Accumulated evidence from dozens of cash transfer (CT) programs across the world suggests that there are few interventions that can match the range of impacts and cost‐effectiveness of a small, predictable monetary transfer to poor families in developing countries. However, individual published impact assessments typically focus on only one program and one outcome. This article presents two‐year impacts of the Zambian Government's Child Grant, an unconditional CT to families with children under age 5, across a wide range of domains including consumption, productive activity, and women and children's outcomes, making this one of the first studies to assess both protective and productive impacts of a national unconditional CT program. We show strong impacts on consumption, food security, savings, and productive activity. However, impacts in areas such as child nutritional status and schooling depend on initial conditions of the household, suggesting that cash alone is not enough to solve all constraints faced by these poor, rural households. Nevertheless, the apparent transformative effects of this program suggest that unconditional transfers in very poor settings can contribute to both protection and development outcomes.     

LABOR FORCE PARTICIPATION AND POVERTY STATUS AMONG RURAL AND URBAN WOMEN WHO HEAD FAMILIES

This paper examines differentials in the propensity to be living in poverty among women who head families with minor children. Characteristics of mothers are examined for four subgroups: residents of central cities, suburbs, small towns, and rural areas. Using Public Use Microdata Sample data from the 1980 Census, results are presented using Multiple Classification Analysis. After controlling for the effects of mother's race, marital status, education, work status, and ages of her children, single mothers in central cities and smaIl towns have the highest rates of poverty (48% and 45% respectively), closely followed by those in rural areas (41%). Suburban single mothers are least likely to live in poverty (33%).
Results show that employment status is the strongest predictor of poverty, followed by education and marital status. A subanalysis of women who work full-time reveals major differences in earned income, with suburban women earning the highest incomes, followed by women living in central cities, then rural areas and, finally, small towns. A decomposition of this difference reveals that about two-thirds of the difference is due to pay scales, and only one-third due to the structure of occupational opportunity.     

Recent changes in the Mexican industrial labor force

"We study...some of the repercussions of the crisis and economic restructuring on the manufacturing labour force in the main urban areas of Mexico. Using the data of the National Survey of Urban Employment for the period 1986-1992, we set, first of all, the evolution of female and male presence in the manufacture of the country's main industrial cities. Further, some of the characteristics of the manufacturing labour force in different types of cities are examined. For this purpose, we are considering several issues: the condition of wage earner and non-wage earner workers, the size of the establishment, some sociodemographic aspects (gender, age, schooling level, and condition of the head of household), as well as different aspects related to labour conditions (length of workday, job benefits, and salary levels)."

解读技术非中性论

在技术非中性论看来，现代技术在本质上是非中性的，具有先验性、普遍性、自主自律性、宗教性的基本特征，是构成支配社会历史发展和人的生存命运的惟一逻辑。技术非中性论对技术地位作用的绝对化强调，否定了人的创造性实践活动在社会历史发展中的根基性决定地位，忽视了人与技术之间的相互作用。     

Development and evaluation of a survey-based type of benefit classification for the Social Security program

This attempt to classify Social Security beneficiaries by type of benefit using the new Survey of Income and Program Participation (SIPP) has yielded promising results. Evaluations of the classification algorithm based on comparison of the estimated number of beneficiaries in each of the several categories to independent estimates of the number of beneficiaries indicate that in most instances a high percentage of each category has been identified. For the most part, age and monthly benefit amount size distributions seem reasonable. Furthermore, very few persons in the sample who were identified as Social Security beneficiaries could not be assigned to one or another of the benefit groups. The classification procedure also represents a marked improvement over earlier efforts to classify type of beneficiary that relied on data from the March Supplement to the Current Population Survey (CPS). Most importantly, the benefit classification scheme based on SIPP data appears to provide reasonably reliable distinctions between retired-worker and widow benefits for widowed women and permits the identification of retired-worker benefits for those women dually entitled to retired-worker and spouse benefits. In addition, the distinction between disabled- and retired-worker benefits for recipients aged 62-64 appears to be reasonably reliable, and for women under age 65, the classification procedure distinguishes between disabled-worker benefits on the one hand and widow and widowed mother benefits on the other. Finally, SIPP procedures for identifying minor child beneficiaries yield markedly better estimates than those available from the Current Population Survey. These improvements in the SIPP context are due entirely to the presence of information not collected in the CPS. The enhancement of the SIPP data set in turn resulted directly from an assessment of earlier work carried out by Projector and Bretz in the CPS context and on extensive research into the nature of Social Security reporting errors in the CPS. The superiority of the SIPP data set is linked principally to the presence of three pieces of information: the Medicare BIC, the direct question on reasons for benefit receipt asked of persons under age 65, and the direct measurement of recipiency and amount of benefits for minor children. Other items of some import include self-reported work disability, retirement status (ever retired from a job), previous marital status for currently married women, age first prevented from working due to a health condition, and Supplemental Security Income misreporting items.(ABSTRACT TRUNCATED AT 400 WORDS)     

Projecting retirement income of future retirees with panel data: results from the modeling income in the near-term (MINT) project

Cross-sectional data capture only a point in time and miss individual changes in earnings, labor force participation, marriage, fertility, and health. Because panel data follow individuals over time, they do not have this problem. The problems or concerns with cross-sectional data may be compounded when these data are used to make projections. Iams and Sandell (1997) found that using panel data on earnings explained much more variation in future earnings than using cross-sectional survey data. Panel data are also needed to estimate Social Security benefits, especially for women. Because of auxiliary benefits paid to spouses, ex-spouses, and widow(er)s of entitled workers, an individual's Social Security retirement benefit depends not only on his or her earnings history, but also on his or her marital history and the earnings histories of current and previous spouses. When we compare projected unreduced Social Security benefits with what they would be if we didn't have marital history or earnings history data for men, we find that: Benefits computed using only earnings histories are not very different from benefits computed using both earnings and marital histories. Benefits computed using only current earnings and marital histories underestimate benefits for those in earlier birth cohorts and overestimate benefits for those in the most recent birth cohort. Benefits computed without either marital or earnings histories underestimate benefits for all birth cohorts, but by much more for earlier cohorts than for more recent cohorts. For women we find that benefits computed without marital or earnings histories underestimate benefits in all birth cohorts. The largest differences are for women in earlier birth cohorts. Using both marital and earnings histories to estimate unreduced Social Security benefits, we find that men are projected to continue receiving higher benefits than women, although the gap is expected to narrow as the baby boomers near retirement age. We also look at the composition of projected total income available at retirement for those with incomes in the 45th-55th percentiles of the income distribution and find that: Total income at retirement is projected to be larger for men than for women in every birth cohort. Women are projected to receive the largest share of their total income from Social Security benefits. Men are projected to receive the largest share of their total income from other income sources, although this share declines as the baby boomers near retirement age.
