Payoff from different kinds of fundraising approaches

Prospective donors contacted during a Texas A&M campaign tended to give the university more when they either automatically got luggage tags as part of the solicitation or when they received those trinkets once they had donated. The cost of giving donors the tags outweighed the gains.

Differences in the amounts raised per solicitation were not meaningful for the conditional treatments with the plastic and leather tags and were primarily driven by outliers, so the data is pooled.
