The (In)Visible Hand : Do Workers Discriminate Against Employers? ∗

Although a large literature has studied discrimination in the labor market, there is little evidence on sex- and race-based discrimination of employees against (potential) employers. We implement a randomized experiment in an online labor market to contribute to this gap in the literature. In our experiment, workers make labor-supply decisions after we randomly expose them to signals about the race and sex of the employer. We find evidence of discrimination on the quality of work, but not on the general willingness to work in our labor task. Our results also suggest that discriminating employees try to conceal their behavior ex-post. An additional survey with randomized components suggests that our results are not driven by statistical discrimination
