In collaboration with the French employment agency Pôle Emploi, researchers evaluated whether making resumes anonymous can actually reduce discrimination. Recruiting firms working with Pôle Emploi to find employees were asked to participate in the experiment, and those who agreed were randomly allocated into a treatment and a comparison group. In the treatment group, resumes coming from the employment agency were made anonymous by removing both the candidates name and address. In the comparison group, resumes coming from the employment agency included this information. It is important to note that in both treatment and comparison groups, employers were receiving resumes from other sources than Pôle Emploi.
There were 385 control and 366 treatment firms that participated in the experimental program and went through the randomization. In addition, 254 firms accepted the program but were not randomly assigned to treatment or control; they canceled or filled the job opening before a first pool of résumés was collected and randomization could take place.
