In the study "Are Emily and Brendan More Employable than Lakisha and Jamal?" Marianne Bertrand, an associate professor at the University of Chicago Graduate School of Business, and Sendhil Mullainathan of Massachusetts Institute of Technology use a field experiment to measure the extent of race-based job discrimination in the current labor market.
From July 2001 to May 2002, Bertrand and Mullainathan sent fictitious resumes in response to 1,300 help-wanted ads listed in the Boston Globe and the Chicago Tribune. They used the callback rate for interviews to measure the success of each resume. Approximately 5,000 resumes were sent for positions in sales, administrative support, clerical services, and customer service. Jobs ranged from a cashier at a store to the manager of sales at a large firm.
The catch was that the authors manipulated the perception of race via the name of each applicant, with comparable credentials for each racial group. Each resume was randomly assigned either a very white-sounding name (Emily Walsh, Brendan Baker) or a very African-American-sounding name (Lakisha Washington, Jamal Jones).
The authors find that applicants with white-sounding names are 50 percent more likely to get called for an initial interview than applicants with African-American-sounding names. Applicants with white names need to send about 10 resumes to get one callback, whereas applicants with African-American names need to send about 15 resumes to achieve the same result
