Inequality at Birth: Some Causes and Consequences
研究发现，母亲教育程度和种族影响胎儿污染暴露，进而导致新生儿健康不平等，污染暴露差异可解释不同群体间低出生体重差距的6%。
Recent research shows that health at birth is affected by many factors, including maternal education, behaviors, and participation in social programs. In turn, endowments at birth are predictive of adult outcomes, and of the outcomes of future generations. Exposure to environmental pollution is one potential determinant of health at birth that has received increasing attention. A large literature outside of economics advocates for Environmental Justice, and argues that poor and minority families are disproportionately exposed to environmental hazards. I provide new evidence on this question, showing that children born to less educated and minority mothers are more likely to be exposed to pollution in utero and that white, college educated mothers are particularly responsive to changes in environmental amenities. I estimate that differences in exposure to toxic releases may explain 6% of the gap in incidence of low birth weight between infants of white college educated mothers and infants of black high school dropout mothers.
