Though many types of early life resources have been linked to adult economic inequality, this research has given little attention to a fundamental resource for healthy development: sleep. This is surprising, because lab experiments and quasi-experimental approaches find a causal effect of inadequate sleep on cognitive performance, emotional processing, and physical health. In addition, youth sleep patterns contribute to lifelong patterns of (un)healthy sleep. To identify how early life sleep predicts adult economic outcomes, I use the National Study of Adolescent to Adult Health, a nationally representative cohort study of adolescents in the United States. I find that adolescents who sleep 7 to 8 hours per night have better educational and occupational outcomes than adolescents with other sleep durations, though there is no statistically significant association with earnings or perceived socioeconomic position. These preliminary results suggest that sleep may be an underappreciated contributor to processes of social stratification.
