We investigate whether a policy that bases college admission on relative performance can modify the degree of racial or ethnic segregation in high schools by inducing students to relocate to schools with weaker competition.

Several prominent applications of the Veil of Darkness (VOD) test, where solar variation is used to identify racial profiling in traffic stops, have found reverse discrimination in cities widely purported to disproportionately target minorities.
