Shang and Croson (2009) found that providing information about the donation decisions of others can have a positive impact on individual donations to public radio. In this study, we attempted to replicate their results, however, we found no evidence of that social comparisons affected donation decisions. Most of our donors were renewing members, a group which Shang and Croson also found were not influenced by social information.
