Summary of Working paper 2005:3

We investigate the relative signiÞcance of differences in cognitive skills and discrimina-
tion in explaining racial/ethnic wage gaps. We show that cognitive test scores taken
prior to entering the labor market are inßuenced by schooling. Adjusting the scores for
racial/ethnic differences in education at the time the test is taken reduces their role in
accounting for the wage gaps. We also consider evidence on parental and child expec-
tations about education and on stereotype-threat effects. We Þnd both factors to be
implausible alternative explanations for the gaps we observe. We argue that policies
need to address the sources of early skill gaps and to seek to inßuence the more mal-
leable behavioral abilities in addition to their cognitive counterparts. Such policies are
far more likely to be effective in promoting racial and ethnic equality for most groups
than are additional civil rights and affirmative action policies targeted at the workplace.
