摘要：We replicate and extend unit asking – a method to increase donations by first asking donors for their willingness to donate for one unit and then asking for donations for multiple units (Hsee, Zhang and Xu, 2013) We conducted a large scale replication and extension using a 2 (unit asking, control) x 3 (domains; children (original), animals, environment) between-subjects design. Across three domains, we find that unit asking increased donations, suggesting that this method can be used to increase giving to different charitable causes.
