Good health and hospital access in the years immediately after birth = black gains in education and test scores

A previous study by the authors of this study  found demonstrated a close tracking between variation in the test score convergence across states and racial convergence in measures of health and hospital access in the years immediately after birth.  

This study analyzes whether the across-cohort patterns in the black-white education and earnings gaps match those in early life health and test scores already established.  

With Census data, the authors find:  

i) a significant narrowing across the same cohorts in education gaps driven primarily by a relative increase in the probability of blacks going to college; and 
ii) a similar convergence in relative earnings that is insensitive to adjustments for employment selection, as well as time and age effects that vary by race and state-of-residence.  

The variation in racial convergence across birth states matches the patterns in the earlier study.     

The magnitude of the earnings gains is greater than can be explained by only the black gains in education and test scores for reasonable estimates of the returns to human capital.  This suggests that other pre-market, productivity factors also improved across successive cohorts of blacks born in the South between the early 1960's and early 1970's.  Finally, our cohort-based hypothesis provides a cohesive explanation for the aggregate patterns in several, previously disconnected literatures.
