Executive Summary

Introduction

Better health can boost economic opportunity. In particular, health investments early in life can pay dividends in the form of higher employment rates and earnings in adulthood. This study examines a historical case study: the introduction of the first antibiotics in 1937, which dramatically improved survival from childhood infections like pneumonia. It assesses whether access to these medications early in life translated into stronger economic outcomes later in life. It also examines whether these effects differed by race and gender.

Main Findings

  • Infants who benefited from early access to antibiotics generally experienced better economic outcomes as adults, including higher educational attainment, increased employment, and higher earnings.
  • These economic gains were larger for men than for women, reflecting differences in labor-market opportunities and social roles during much of the 20th century. Even when women experienced similar health improvements, those gains were less likely to translate into higher earnings or employment.
  • Racial inequalities further shaped these outcomes. Among Black Americans born in states with high levels of systemic discrimination – which constrained upward mobility in this population — the long-run economic benefits of improved childhood health were much smaller. Impacts for white individuals, in contrast, did not differ by the degree of systemic discrimination.

Conclusion

This study shows that early exposure medical innovation can have powerful, lifelong economic effects, but those benefits depend heavily on the social and economic opportunities available to different groups. Improved infant health led to better adult outcomes most clearly for men and for those not constrained by racial discrimination. These findings highlight that health interventions alone cannot eliminate economic inequality; institutions, labor markets, and social barriers play a central role in determining who benefits from medical progress.
