Can a summer make a difference? The impact of the American Economic Association Summer Program on minority student outcomes

•We estimate the effect of participation in the American Economic Association Summer Program (AEASP) on a range of outcomes.•Program participants were over 40 percentage points more likely to apply to and attend a Ph.D. program in economics.•They were also 26 (15) points more likely to complete a PhD (ever work in an economics-related academic job).•The AEASP may directly account for 17–21 percent of the Ph.D.s awarded to minorities in economics by US universities over the past 20 years.

In the 1970s, the American Economic Association (AEA) was one of several professional associations to launch a summer program with the goal of increasing racial and ethnic diversity in its profession. In this paper we estimate the effectiveness of the AEA's program which, to the best of our knowledge, is the first to rigorously study such a summer program. Using a comparison group consisting of those who applied to, but did not attend, the program and controlling for an array of background characteristics, we find that program participants were over 40 percentage points more likely to apply to and attend a Ph.D. program in economics, 26 percentage points more likely to complete a Ph.D., and about 15 percentage points more likely to ever work in an economics-related academic job. Using our estimates, we calculate that the program may directly account for 17–21 percent of the Ph.D.s awarded to minorities in economics over the past 20 years.
