Black-White Disparities in Test Scores: Distributional Characteristics

This paper investigates the distributional characteristics of racial differences in mathematics achievement, with particular attention to the potential influence of unexplained, and possibly unwarranted, racial differentials in rates of school suspension. It is well known that black students consistently score lower than whites on achievement tests, on average, even after controlling for family and schooling factors. Using data from the National Longitudinal Survey of Youth 1997 cohort, we decompose the racial gap in mathematics test scores from the Peabody Individual Achievement Test-Revised (PIAT-R) into a component due to racial differences in underlying characteristics and another component that is unexplained by differences in measured characteristics. We account for the possible endogeneity of suspensions in our analysis and show that the portion of the racial gap that is unexplained differs between the top and the bottom of the test score distribution. Our results suggest that researchers should pay more attention to the problem of concentration of black students among those at the bottom of the distribution and their scarcity among those at the top of the test score distribution to better understand the factors that account for the observed disparities.     

Inequality and infant and childhood mortality in the United States in the twentieth century

This paper deals with the issue of using infant and childhood mortality as an indicator of inequality. The case is that of the United States in the 20th century. Using microdata from the 1900 and 1910 Integrated Public Use Microsamples (IPUMS), published data from the Birth Registration Area in the 1920s, results from a number of surveys, and the Linked Birth & Infant Death Files from the National Center for Health Statistics for 1991, infant and child mortality can be related to such other variables as occupation of father or mother, education of father or mother, family income, race, ethnicity, and residence. The evidence shows that, although there have been large absolute reductions in the level of infant and child mortality rates and also a reduction in the absolute levels of differences across socioeconomic groups, relative inequality has not diminished over the 20th century.     

Infant mortality decline in rural and urban Bavaria: fertility,economic transformation,infant care,and inequality in Bavaria and Munich, 1825–1910†

During most of the nineteenth century, Bavaria was notorious for infant mortality rates that were among the highest in Europe. After 1870, infant mortality in Bavaria began a sustained decline. This decline, which was impressive in urban areas, was even more dramatic in Bavaria's capital, Munich. From a peak of 40 deaths per 100 births in the 1860s, infant mortality had fallen two‐thirds by 1914. This article examines the causes of infant mortality in rural and urban districts of Bavaria from 1880 to 1910 and in Munich from 1825 up to shortly before the First World War. In rural Bavaria, structural change in agriculture lowered infant mortality, even as stark differences in infant survival driven by income gaps and deficient infant care remained. In urban areas, high fertility was strongly associated with high infant mortality. Individual‐level data from Munich reveal that infant care, fertility, and incomes mattered. Even prior to industrialization, occupational status influenced infant survival. Munich's growth into a leading industrial centre after 1875 apparently widened the gap between rich and poor. Families at the top of the occupational distribution and couples able to acquire real property saw the steepest declines in infant mortality. The poorest one‐third without property saw little improvement.     

Racial Earnings Disparities and Family Structure

One explanation for the widening of racial earnings gaps among family heads during the 1980s is that black families were increasingly headed by females during that period. This explanation is tested using data on black and white family heads in 1976 and 1985 from the Institute for Research on Poverty's Current Population Survey. Log-earnings equations, corrected for selection bias and for the endogeneity of labor force participation, are estimated for blacks and whites in 1976 and 1985. If the impact of rising female-family headship on labor force participation is ignored, one finds support for the family structure explanation. But support for alternative explanations is also found. There are substantial impacts of within-race gender discrimination and of market racial discrimination. When the endogeneity of family structure is taken into account, further support is found for the view that endowment differences only explain a modest portion of the rising gap in earnings between black and white family heads.     

The village midwife program and infant mortality in Indonesia

Indonesia introduced over 50,000 midwives into villages in the 1990s to provide primary care to women lacking easy access to health facilities. It seems plausible to argue that the significant reduction in infant mortality that occurred from about 1993–94 was a consequence of this. The paper estimates the village midwife program's impact on infant mortality, using data from the Indonesia Family Life Survey. Regressing mortality outcomes against choice of services would lead to biased estimates because of the correlation between service choice and unobserved individual characteristics. Furthermore, non-random placement of midwives could bias estimates of their impact on infant mortality. This study overcomes such endogeneity problems by aggregating mortality outcomes and program prevalence at district level and taking account of district fixed effects in estimating the program's impact. Surprisingly, the results do not support the hypothesis that the midwife program was responsible for the observed decline in infant mortality.     

Bold Policies for Economic Justice

The U.S. is characterized by a longstanding pattern of large structural racial inequality that deepens further as a result of economic downturn. Although there have been some improvements in the income gap up until around the mid 1970s, the employment gap, and the racial wealth gap - two dramatic indicators of economic security - remains exorbitant and stubbornly persistent. We offer two race-neutral programs that could go a long way towards eliminating racial inequality, while at the same time providing economic security, mobility and sustainability for all Americans. The first program, a federal job guarantee, would provide the economic security of a job and the removal of the threat of unemployment for all Americans. The second program, a substantial child development account that rises progressively based on the familial asset positioning of the child??s parents, would provide a pathways towards asset security for all Americans regardless of their economic position at birth.     

Determinants of fertility in developing countries

The contribution of agricultural modernization to changes in fertility in developing countries was examined. A model for the determinants of both fertility and infant mortality--hypothesized to be positively related--was specified and applied to cross-sectional data for 75 developing countries for the year 1971. The infant mortality rate, productivity per unit of labor and land, and density of population for agricultural land were highly correlated with the crude birth rate. The only other exogenous variables highly correlated with each other were productivity per unit of labor and infant mortality, and productivity per unit of land and population density for agricultural areas. The coefficient of population density of agricultural areas suggested a negative impact of density on fertility. The infant mortality rate, productivity per unit of land and labor, and density of population of agricultural areas explained 85% of the intercountry variation in fertility. The infant mortality rate, productivity of land, and productivity of labor were of descending order of importance in determining the crude birth rates in the countries analyzed. 68% of the intercountry variation in infant mortality was explained by fertility, adult literacy, per capita energy consumption, gini-coefficient of income distribution, population per hospital bed, and protein supply. Adult literacy, crude birth rates, population per hospital bed, per capita energy consumption, per capita protein supply, and gini-coefficient of income distribution were of descending order of importance in determining infant mortality rates. All of the variables that affected infant mortality directly affected fertility indirectly; conversely, all the variables that affected fertility directly affected infant mortality indirectly. Overall, these results confirm that agricultural modernization does exert an effect on fertility. The task in developing countries is to break the vicious cycle of infant mortality and fertility. This can be achieved both through family planning programs and the diffusion of health programs to lower infant mortality.     

Ethnic-specific infant care practices and infant mortality in late Imperial Russia

The Russian Empire had the highest infant mortality rate in Europe at the beginning of the twentieth century. Using a variety of official statistical sources and qualitative evidence, this paper documents uniquely high infant mortality among ethnic Russians. In contrast, among other ethnic groups of the empire, infant mortality rates did not exceed those of the European countries by much. The evidence suggests that the explanation for the Russian infant mortality pattern was ethnic-specific infant care practices, such as the early introduction of solid food, which increased the incidence of lethal gastrointestinal diseases. Our findings highlight the importance of traditional infant feeding practices in mortality in pre-industrial societies.     

Can ‘Baby Bonds’ Eliminate the Racial Wealth Gap in Putative Post-Racial America?

Despite an enormous and persistent black-white wealth gap, the ascendant American narrative is one that proclaims that our society has transcended the racial divide. The proclamation often is coupled with the claim that remaining disparities are due primarily to dysfunctional behavior on the part of blacks. In such a climate it appears the only acceptable remedial social policies are those that are facially race neutral. However, even without the capacity to redistribute assets directly on the basis of race, our nation still can do so indirectly by judiciously using wealth as the standard for redistributive measures. We offer a bold progressive child development account type program that could go a long way towards eliminating the racial wealth gap.     

Demographic consequences of maternal-leave programs in industrial countries: evidence from fixed-effects models

The authors measure the effects of paid maternity leave upon infant mortality, the labor force participation of women during their prime childbearing years, and fertility rates. To reach their conclusions, they constructed a simultaneous-equations model using the individual fixed-effects method and a data set comprising 17 OECD countries and four time periods. The extension of maternal leave programs, measured in terms of duration of paid leave, is shown to reduce infant mortality, to raise rates of labor force participation for women in the prime childbearing ages, and to increase birth rates. The direct plus indirect impacts of extending maternity leave programs, as revealed by the reduced-form parameters of the authors' models, however, produce a different picture. The total impacts upon both infant mortality and female labor force participation conform closely to the structural estimates, but the impact upon birth rates almost disappears. It seems that the indirect effects of the maternal leave variable, via infant mortality and women's labor force participation, offset the directly pronatal influence. From a policy perspective, the benefits of paid maternal leave programs would seem to be unconditionally positive with respect to lowering infant mortality, and also positive with respect to raising female labor force participation. One should not, however, expect higher birth rates from such programs. The findings also suggest that maternal leave programs can facilitate some increases in women's labor force participation without incurring the reductions in fertility which would otherwise be experienced.     

INVESTIGATING THE GENDER GAP IN SOUTH AFRICAN TRADE UNION MEMBERSHIP: A DECOMPOSITION ANALYSIS

This paper investigates the gender difference in trade union membership among African men and women in South Africa. Using labour force survey data for 2001 and 2007, we show that at least two thirds of the gender gap is explained by differences in union‐related characteristics. When compared with gender differences in personal, household‐ and job‐related characteristics, disparities in job characteristics account for a larger proportion of the gender gap. These findings imply that women would have had higher unionisation rates than men if they possessed male endowments of union‐related characteristics, especially access to unionised jobs.     

Infant Mortality Decline and Its Socioeconomic Correlates in New Zealand, 1873–1940

The popular view of New Zealand during the first half of the twentieth century is one of a healthy country with exceptionally low infant mortality rates. This article reviews the non-Māori ‘health transition’ and its determinants from a socioeconomic perspective and draws comparisons with Australia. Regional health inequalities are analysed through the lens of infant mortality. Socioeconomic correlates with infant mortality are investigated empirically. Panel regression estimates suggest that during the 1874–1919 period, improvements in real wages corresponded with falling infant deaths and thus better health outcomes, while increased housing density created unfavourable conditions for infant survival chances.     

The Impact of Medical Education Reform on the Racial Health Status Gap, 1920–1930: A Difference-in-Differences Analysis

The racial impact of a quantity–quality tradeoff in physician supply (implemented through medical education reform) made during an era of racial segregation is assessed. The reform produced differential impacts across race and region. The health status of northern blacks improved the most; that of southern blacks the least. Accordingly, the health status gap between northern whites and blacks diminished, but the gap between southern blacks and every other demographic group increased. The path of northern blacks suggests that access to and high quality of health care are both necessary to close the racial gap in health status that persists today.     

Basic needs policies and population growth

Multiple regression analysis is applied to a newly-published body of cross-country data: (a) to re-examine the effects on fertility of infant mortality, education, and the degree of equality of the income distribution; (b) to test for the existence of a lag between the decline in fertility; (c) to investigate whether interaction effects occur. It is found that basic needs oriented policies may indeed bring about an eventual decline in fertility rates as well as mortality rates — but that the full long-run effect of such policies on population growth is likely to depend crucially on the length and time-shape of the lag between the fertility and mortality reductions.     

Four themes in fertility research

This study is concerned with four main themes that have been combined to describe U.S. fertility trends since 1920. These themes are identified as a time adjustment mechanism, income, the wife's labor force activities, and some intergenerational factor. "In order to obtain an unambiguous picture each theme will be represented by only one variable. After selecting the variables and estimating a model, an examination of the changing role these variables have had in explaining changes in fertility (the total fertility rate) throughout much of this century will be made. Finally, the implications these themes have for future fertility will be examined." The authors conclude that "in interpreting historical U.S. fertility rates, the results seem to indicate that much of the early decline in U.S. fertility was due to falling infant mortality. After the Second World War, fertility rose sharply as the age-structure variable declined and income rose. Eventually both women's labor force participation rates and the age-structure variable rose and, consequently, fertility fell." They also suggest that the age structure variable may cause a temporary upward swing in fertility in the near future.     

Patterns of infant mortality in rural England and Wales, 1850–1910†

The study of nineteenth‐century infant mortality in Britain has neglected the rural dimension to a surprising degree. This article maps the change in infant mortality rate (IMR) between the 1850s and the 1900s at registration district (RD) level. Latent trajectory analysis, a longitudinal model‐based clustering method, is used to identify the clusters into which rural RDs fell, based on their IMR trajectories. Relationships between IMR and population density, fertility, female tuberculosis mortality, female illiteracy, male agricultural wages, and distance from London are examined in a longitudinal study. The tuberculosis (maternal health), illiteracy (education), and distance variables had the most effect. IMR responded most strongly to improving health and education in the east, less in the central area, and least in the north and west. The eastern zone's higher‐than‐average mid‐century infant mortality therefore declined faster than the national average. A central and southern zone had slightly lower IMR in mid‐century but did not keep up with the rate of decline in the east. The peripheral north and west had the lowest mid‐century rates but their decline was overtaken by the other zones. The interpretation of these findings and their relevance to the wider study of infant mortality are discussed.     

What the Achievement Gap Conversation is Missing

There is a persistent achievement gap that persists between students of color and their white counterparts. This is a national crisis and is one of the biggest problems facing American society. However, this research should consider two phenomena regarding the gap: adolescent perceptions of racial discrimination and racial identity. Among African American youth, perceptions of discrimination have been negatively linked to diminished achievement motivation, grade point average and school engagement. Yet, racial identity has been shown to be an effective protective factor for perceived discrimination in relation to academic achievement. Thus, addressing the achievement gap requires consideration of these two complex constructs for African American youth.     

Health Expenditures and Health Outcomes in Africa*

Abstract: This paper provides econometric evidence linking African countries’ per capita total as well as government health expenditures and per capita income to two health outcomes: infant mortality and under‐five mortality. This relationship is examined using data from 47 African countries between 1999 and 2004. Health expenditures have a statistically significant negative effect on infant and under‐five mortality rates. The magnitude of our elasticity estimates are in consonance to those reported in the literature. For African countries, our results imply that total health expenditures (as well as the public component) are certainly important contributors to health outcomes. In addition, we find that both infant and under‐five mortality are positively and significantly associated with sub‐Saharan Africa. The reverse is true for North Africa. While ethnolinguistic fractionalization and HIV prevalence positively and significantly affect the health outcomes, higher numbers of physicians and female literacy significantly reduce these health outcomes. These results have important implications for attaining the targets envisioned by the Millennium Development Goals. The data implications are also discussed.     

Quantifying the impact of aid to dependent children: An epidemiological framework

This paper shows that conditional cash transfers under Aid to Dependent Children (ADC), a main program of the 1935 Social Security Act, reduced infant, children and adult mortality. I take advantage of the transition from mothers’ pensions to ADC and the large differences in ADC payments and eligibility across 104 cities, 2,260 counties, and 49 states to estimate the impacts of cash transfers on mortality rates, by age, sex, race, and cause between 1929 and 1944. I find that ADC's expansion reduced infant and adult mortality by between 10 and 20 percent. This finding, based on an event-study design, is robust to a range of specifications, difference-and-differences, an instrumental variable strategy, a range of fixed effects, placebo tests and a border-pair policy discontinuity design. The largest mortality reductions came from drops in communicable and infectious diseases, such as influenza, pneumonia and tuberculosis.     

Using the Blinder-Oaxaca Decomposition Method to Measure Racial Bias in Achievement Tests

The Blinder-Oaxaca decomposition technique is typically applied to gender or racial earnings gaps with the goal of determining the percent of the gap that can be attributed to differences in attributes between groups and to labor market discrimination. We apply this technique to the racial gap in achievement tests with the goal of measuring the relative racial bias of these tests. The Armed Services Vocational Aptitude Battery (ASVAB) and the Peabody Individual Achievement Test (PIAT) were administered to respondents from the 1997 National Longitudinal Survey of Youth. Decomposition results indicate that up to 49.5 % of the white-black gap in the PIAT is explained by racial differences in average attributes. The corresponding figure for the ASVAB is 44.7 %. Since the same sample and specification are used in estimating ASVAB and PIAT scores, the difference in the percent of the gaps due to attributes can be ascribed to test score bias and not omitted variable bias. Therefore, the results suggest that the “discrimination” or bias of the ASVAB is greater than the PIAT.
