“…Similar to previous studies that have looked at static gaps in black-white earnings and college-going rates using NLSY data (for example, Neal and Johnson, 1996;Cameron and Heckman, 2001), it is apparent that the cumulative effects of a variety of influences that affect cognitive ability by adolescence play a critical role in accounting for racial differences in upward and downward mobility. A growing literature has shown that black-white differences in test scores, and military test scores in particular, have been narrowed through large-scale policy interventions throughout American history (for example, Chay, Guryan, and Mazumder, 2009;Aaronson and Mazumder, 2011). Other studies (for example, Dobbie and Fryer, 2011) have also shown the potential for modern educational interventions to improve the black-white gap in educational achievement.…”
