Steffen ALTMANN (University of Copenhagen) – “Defaults and Donations: Evidence from a Field Experiment ”
Abstract: We study how defaults affect charitable donations. In a ﬁeld experiment that was conducted on a large online charitable donations platform, we exogenously vary the default options in two distinct choice dimensions. The ﬁrst pertains to the primary donation decision, namely, how much to contribute to the charitable cause. The second relates to a “codonation” decision of how much to contribute to supporting the online platform itself. We ﬁnd a strong impact of defaults on individual behavior: in each of our treatments, the modal positive contributions in both choice dimensions invariably correspond to the speciﬁed default amounts. Defaults, nevertheless, have no signiﬁcant effects on average donation levels. This is because defaults in the donation domain induce some people to donate more and others to donate less. In contrast, higher defaults in the secondary choice dimension unambigously induce higher average contributions to the online Platform.
