Maternal height and child health and schooling in sub-Saharan Africa: Decomposition and heterogeneity

Maternal height is associated with mortality and anthropometry in low-and-middle-income countries. This paper explored residual associations and potential underlying mechanisms linking maternal height to several child outcomes using regression models with neighborhood and half-sibling fixed effects and Gelbach decomposition on 108 Demographic and Health Surveys from 37 sub-Saharan African countries. When adjusting for time of birth, twinning, sex, and survey, a single z-score (6.5 cm) increase in mother's height was associated with a 22% reduction in the average deficit in height-for-age among children under five (according to the WHO 2006 growth standard), 16% lower neonatal mortality (age <1 month) , 10% lower postneonatal mortality (age 1-11 months), 11% lower child mortality (age 12-59 months) , and 2% increase in school attendance among 7-16-year-olds. Adjusting further for maternal education, household living standards, maternal fertility and birth related factors, and neighborhood reduced the coefficients for maternal height by 22% for child height-for-age, 26% for neonatal mortality, 46% for postneonatal mortality, 56% for child mortality, and 90% for school attendance. The decomposition showed that adjusting for neighborhood had a substantial impact on the association of maternal height with all outcomes, especially child mortality. Adjusting for unobserved father and household factors also had a particularly large impact on the association with child mortality. The robustness of the relationship with neonatal mortality suggests that pregnancy and perinatal factors are an important link between maternal height and child outcomes. Adult living standards and socioeconomic and related behavioral factors likely play a small role. Genetics may also play a large role in linking maternal height and child height-for-age, especially for educated mothers, whose height was presumably impacted less by early life adversity.

Employment Discrimination against Indigenous Peoples in the United States: Evidence from a Field Experiment

We conducted an audit study - a resume correspondence experiment - to measure discrimination in hiring faced by Indigenous Peoples in the United States (Native Americans, Alaska Natives, and Native Hawaiians). We sent employers 13,516 realistic resumes of Indigenous or white applications for common jobs in 11 cities. We signalled Indigenous status in one of four different ways. Interview offer rates do not differ by race, which holds after an extensive battery of robustness checks. We discuss multiple concerns such as the saliency of signals, selection of cities and occupations, and labour market tightness that could affect the results of our audit study and those of others. We also conduct decompositions of wages, unemployment rates, unemployment durations, and employment durations to explore if discrimination might exist in contexts outside our experiment. We conclude by highlighting the essential tests and considerations that are important for future audit studies, regardless of if they find discrimination or not.
