Discrimination in a World of Racial Fluidity

Interesting tidbit from a study of race and income in Brazil:

In Brazil, different employers often report different racial classifications for the same worker. We use this variation in employer-reported race to identify wage discrimination. Workers whose reported race changes from non-white to white receive a wage increase; those who change from white to non-white realize a symmetric wage decrease. As much as 40 percent of the raw racial wage gap is explained by the employer’s report of race, after controlling for all individual characteristics that do not change across jobs. The results are consistent with workers manipulating perceived race in an environment where racial classification is subjective, but discrimination persists.
