More stats on Radiohead's "Dictator Game"

In a previous post, I tried to analyze the sales of Radiohead's last album (fans decide how much they want to pay for downloading the album). I suggested that it was analogous (but not exactly) to a dictator game. More stats are now available at comscore.com about the downloads and payments: 38% paid for download [62% downloaded for free] Those who paid spent an average of $6.00 (given that buying an album through Itunes costs $9.99, that's like giving 60% of the "pie"). 44% of those who paid (17% of all downloaders) paid between $0,01 and $4,00. So 3 out of 5 users are "freeloaders", and almost half of the payers sent $4 or less. Since it is (almost) an anonymous dictator game (DG), that is not really surprising: less publicity, less generosity:

[in Hoffman et al (1996)] we conjectured that the social connection –we called it “distance” –may not have gone far enough in the DG (...) We were surprised, not just that the “double blind” made a large economic difference –giving nothing rose from 20% to 64% –but that, by relaxing the double blind conditions incrementally, the results stepped down incrementally to the baseline.

[Cherry et al. (2002)| compare endowments given by the experimenter with money earned by the subjects: the percent of dictators giving nothing jumps from 19% to 79%. And the latter rises to 97% when double blinded. Strengthening the sense that the stakes belong to the dictator, combined with “no one can know” his or her decision, all but eliminates dictator giving.
