Early results of a natural experiment evaluating the effects of a local minimum wage policy on the diet-related health of low-wage workers, 2018-2020.

OBJECTIVE: The current study presents results of a midpoint analysis of an ongoing natural experiment evaluating the diet-related effects of the Minneapolis Minimum Wage Ordinance, which incrementally increases the minimum wage to $15/h. DESIGN: A difference-in-difference (DiD) analysis of measures collected among low-wage workers in two U.S. cities (one city with a wage increase policy and one comparison city). Measures included employment-related variables (hourly wage, hours worked and non-employment assessed by survey questions with wages verified by paystubs), BMI measured by study scales and stadiometers and diet-related mediators (food insecurity, Supplemental Nutrition Assistance Program (SNAP) participation and daily servings of fruits and vegetables, whole-grain rich foods and foods high in added sugars measured by survey questions). SETTING: Minneapolis, Minnesota and Raleigh, North Carolina. PARTICIPANTS: A cohort of 580 low-wage workers (268 in Minneapolis and 312 in Raleigh) who completed three annual study visits between 2018 and 2020. RESULTS: In DiD models adjusted for time-varying and non-time-varying confounders, there were no statistically significant differences in variables of interest in Minneapolis compared with Raleigh. Trends across both cities were evident, showing a steady increase in hourly wage, stable BMI, an overall decrease in food insecurity and non-linear trends in employment, hours worked, SNAP participation and dietary outcomes. CONCLUSION: There was no evidence of a beneficial or adverse effect of the Minimum Wage Ordinance on health-related variables during a period of economic and social change. The COVID-19 pandemic and other contextual factors likely contributed to the observed trends in both cities.

Occupational Segregation And Hypertension Inequity: The Implication Of The Inverse Hazard Law Among Healthcare Workers.

In the United States (US), Black-particularly Black female-healthcare workers are more likely to hold occupations with high job demand, low job control with limited support from supervisors or coworkers and are more vulnerable to job loss than their white counterparts. These work-related factors increase the risk of hypertension. This study examines the extent to which occupational segregation explains the persistent racial inequity in hypertension in the healthcare workforce and the potential health impact of workforce desegregation policies. We simulated a US healthcare workforce with four occupational classes: health diagnosing professionals (i.e., highest status), health treating professionals, healthcare technicians, and healthcare aides (i.e., lowest status). We simulated occupational segregation by allocating 25-year-old workers to occupational classes with the race- and gender-specific probabilities estimated from the American Community Survey data. Our model used occupational class attributes and workers' health behaviors to predict hypertension over a 40-year career. We tracked the hypertension prevalence and the Black-white prevalence gap among the simulated workers under the staus quo condition (occupational segregation) and the experimental conditions in which occupational segregation was eliminated. We found that the Black-white hypertension prevalence gap became approximately one percentage point smaller in the experimental than in the status quo conditions. These findings suggest that policies designed to desegregate the healthcare workforce may reduce racial health inequities in this population. Our microsimulation may be used in future research to compare various desegregation policies as they may affect workers' health differently.

The Economic Benefits of Reducing Racial Disparities in Health: The Case of Minnesota.

This paper estimates the benefits of eliminating racial disparities in mortality rates and work weeks lost due to illness. Using data from the American Community Survey (2005⁻2007) and Minnesota vital statistics (2011⁻2015), we explore economic methodologies for estimating the costs of health disparities. The data reveal large racial disparities in both mortality and labor market non-participation arising from preventable diseases and illnesses. Estimates show that if racial disparities in preventable deaths were eliminated, the annualized number of lives saved ranges from 475 to 812, which translates into $1.2 billion to $2.9 billion per year in economic savings (in 2017 medical care inflation-adjusted dollars). After eliminating the unexplained racial disparities in labor market participation, an additional 4,217 to 9185 Minnesota residents would have worked each year, which equals $247.43 million to $538.85 million in yearly net benefits to Minnesota.

Vanishing racial disparities in drowning in Florida.

OBJECTIVES: To examine the change in the racial disparity in drowning in Florida from 1970 to 2015 and to analyse the contextual factors associated with white, black and Hispanic drowning rates in Florida from 2007 to 2015. METHODS: Our outcome variable is county-level annual drowning rates by race, ethnicity, sex and age group. We computed county-level contextual data, including emergency weather events, temperature, extreme weather, number of pools, quality of pools, coastline, swimming participation rates and prominent black competitive swim teams. RESULTS: Between 1970 and 1990, the disparity in drowning rates between white and black males in Florida decreased dramatically. By 2005, the overall age-adjusted drowning rates converged. This convergence was most striking for those aged 10-34 and 35-64. While the gap has declined dramatically, there remains a racial disparity in drownings among those aged 10-34. CONCLUSIONS: Overall, racial disparities in drowning have disappeared in Florida. However, some disparities remain. There is a persistent disparity in drownings among those aged 10-34.

Racial Differences in the Effect of Marriageable Males on Female Family Headship.

Female family headship has strong implications for endemic poverty in the United States. Consequently, it is imperative to explore the chief factors that contribute to this problem. Departing from prior literature that places significant weight on welfare-incentive effects, our study highlights the role of male marriageability in explaining the prevalence of never-married female family headship for blacks and whites. Specifically, we examine racial differences in the effect of male marriageability on never-married female headship from 1980 to 2010. By exploiting data from IPUMS-USA (N = 4,958,722) and exogenous variation from state-level sentencing reforms, the study finds that the decline in the relative supply of marriageable males significantly increases the incidence of never-married female family headship for blacks but not for whites.

Competitive Swimming and Racial Disparities in Drowning.

This paper provides compelling evidence of an inverse relationship between competitive swimming rates and drowning rates using Centers for Disease Control and Prevention (CDC) data on fatal drowning rates and membership rates from USA Swimming, the governing organization of competitive swimming in the United States. Tobit and Poisson regression models are estimated using panel data by state from 1999-2007 separately for males, females, African Americans and whites. The strong inverse relationship between competitive swimming rates and unintentional deaths through fatal drowning is most pronounced among African Americans males.

The Production of Black Ph.D.'s in Economics at Harvard University, 1905-1955.

Harvard University's Economics Department produced some of the leading African American economists between World War I and the Korean War. This essay explores the factors that contributed to this accomplishment and documents the career trajectories of the six blacks who obtained the Doctorate in Economics from Harvard University during the period 1905-1955. The analysis reveals the pivotal roles of the Rosenwald Fund, Classical High Schools, Black Fraternal Organizations and former University of Minnesota Applied Economics Professor, John D. Black. A common outcome of the careers of these six pioneers was a commitment to black economic empowerment.

Does affirmative action in Chinese college admissions lead to mismatch? Educational quality and the relative returns to a baccalaureate degree for minorities in China.

This paper provides a unique illustration of the benefits of affirmative action in higher educaiton. It focuses on China in the early 21st Century to gauge the impacts of advantges afforded to ethnic minority group members in admissions to colleges and univerities. It specifically addresses a variant of the mismatch hypothesis that alleges that minority students sorted into higher ranked universities are worse off than equallty qualified minorities attending lower-ranked universities. In particular, we examine the expected earnings of minorities vs non-minorities attending elite vs less selective colleges and universities in China. The paper utilizes data from the 2002 Chinese Household Income Project to estimate the labor market return to graduating from college relative to high school to assess the impact of post-reform affirmative action in college/univerity admissions in China. Parameter estimates of heterogeneous treatment effects reveal that for minorities, the average treatment effect of earning a baccalaureate degree from colleges/universities ranked good and very good is high relative to the Han majority, and for those actually receiving the treatment from colleges/universities ranked good, and would be positive for those who could have earned a baccalaureate degree from colleges/universities ranked good and very good, but did not. Our results suggest that post-reform affirmative action education policies in China have been effective at improving the education and labor market outcomes of minorities, and that existing minority-Han disparities can be eliminated, and Chinese economic growth can be enhanced, by further expanding the pipeline of minorities that complete high school and enter into colleges/universities that grant baccalaureate degrees. Our findings suggest that the mismatch hypothesis cannot be viewed as a universal phenomenon that renders affirmative action in college/university admissions an ineffective policy tool to redress/remedy historic discrimination against minority groups.

Changes in the representation of women and minorities in biomedical careers.

PURPOSE: To examine how efforts and policies to increase diversity affect the relative representation of women and of minority groups within medicine and related science fields. METHOD: The authors of this report used data from the Current Population Survey March Supplement (a product of the U.S. Census Bureau and the Bureau of Labor Statistics that tracks race, ethnicity, and employment) to compute the representation ratios of persons employed in biology, chemistry, and medicine from 1968 to 2009 (inclusive). They derived the representation ratios by computing the ratio of the conditional probability that a member of a given group is employed in a specific skilled science field to the overall probability of employment in that field. Their analysis tested for differences in representation ratios among racial, gender, and ethnic groups and across time among those employed as biologists, chemists, and medical doctors. RESULTS: Representation ratios rose for white females, whose percentage increase in medicine was larger than for any other racial/ethnic group. The representation ratios fell for Hispanics in biology, chemistry, and medicine. The representation ratio rose for African Americans, whose highest percentage increase occurred in biology. Asian Americans, who had the highest representation ratios in all three disciplines, saw a decline in their relative representation in medicine. CONCLUSIONS: The authors have demonstrated that all groups do not benefit equally from diversity initiatives and that competition across related fields can confound efforts to increase diversity in medicine.

Decomposing Black-White differences in child maltreatment.

This article examines conflicting visions of the racial composition of the maltreated populations. The National Child Abuse and Neglect Data System (NCANDS) data shows Blacks are overrepresented among reported and substantiated abuse and neglect cases, while the National Incidence Study of Child Abuse and Neglect (NIS) shows no apparent overrepresentation of children of color. To understand the conflicting evidence, the authors produce from NIS approximate measures of maltreatment rates in NCANDS. Maltreatment rates is broken down into allegation, report and substantiation components. Without disaggregating the data by welfare status, all or most of the racial gap in official maltreatment is found to arise from racial differences in allegations. Disaggregation changes the results. Among welfare cases, on average, half of the Black-White gap in maltreatment is due to racial differences in substantiation. Among nonwelfare cases, about half of the racial gap in official maltreatment is due to racial differences in allegations.
