Munz, Kurt P., Minah H. Jung, and Adam L. Alter (2017), "Charitable Giving to Teachers with the Same Name: A Field Experiment," Special session presented at the Association for Consumer Research Conference San Diego, CA.
In a randomized email field experiment with DonorsChoose.org (N = 30,302), donors who shared a surname with a teacher were more likely to open, click, donate, and donated more to the teacher’s classroom. Different-surname donors were also more generous when they shared a first-letter with the requesting teacher.
