We conduct a long-run evaluation of one of the oldest professional mentoring programs for underrepresented groups in economics, the American Economic Association Mentoring Program (AEAMP). The AEAMP was established to address the underrepresentation of racial/ethnic minority groups by mentoring doctoral students and new Ph.D.s in economics. We compare professional outcomes of mentees with similar individuals from the same Ph.D. cohort who did not participate in the program. While there are no differences for many outcomes, mentees are more likely to hold a tenure-track or tenured position. Our results point to the potential for mentoring programs to address persistent racial/ethnic disparities.
