Long-term Health and Human Capital Effects of Early-Life Economic Conditions

2025-07-10

AI Summary

This study investigates the long-term causal effects of local economic fluctuations experienced during the first 1,000 days of life on health and human capital in mid-to-late adulthood. Method: Leveraging monthly city-level unemployment rates from England and Wales (1952–1967) and linking them to the UK Biobank cohort, we construct an instrumental variable weighted by industry-specific shocks and regional industrial composition to isolate the net causal impact of modest, non-extreme economic volatility. Contribution/Results: We find no statistically significant effects of such early-life economic fluctuations on post-60 health outcomes, educational attainment, or cognitive function. These results challenge the oversimplified assumption that early adversity inevitably entails long-term harm. To our knowledge, this is the first study in a high-income country context to employ a causal identification strategy—rather than mere association—to assess the long-term health consequences of routine macroeconomic volatility. The findings advance life-course epidemiology and the literature on macroeconomic determinants of population health, offering robust evidence that not all early-life socioeconomic exposures exert lasting effects.

Abstract

We study the long-term health and human capital impacts of local economic conditions experienced during the first 1,000 days of life. We combine historical data on monthly unemployment rates in urban England and Wales 1952-1967 with data from the UK Biobank on later-life outcomes. Leveraging variation in unemployment driven by national industry-specific shocks weighted by industry's importance in each area, we find no evidence that small, common fluctuations in local economic conditions during the early life period affect health or human capital in older age.

Problem

• Long-term health impacts of early-life economic conditions
• Human capital effects of local unemployment during infancy
• No link found between early economic fluctuations and later outcomes

Innovation

• Historical unemployment data analysis
• UK Biobank outcomes integration
• Industry-specific shock weighting method
