Do you remember Francesca Gino's claim on her website that HBS analyzed the "wrong data file" in their investigation, and that a "real file" proved her innocence?
HBS is now claiming that the "real file" was fabricated by Gino... and thus that Gino's claim was defamatory.

Feedback is much appreciated!
Institutional rules promote cooperation by strengthening personal and social norms, which in turn sustains contributions over time. In contrast, in the absence of a rule, norms are weaker and contributions decline steadily over time. (5/n)
Surprisingly, we find no evidence that biased audits erode norms, reduce cooperation, or diminish compliance. (4/n)
We find that:
Rules work: Simply having a rule reduces free-riding and increases cooperation.
Adding enforcement leads to exact rule-following and less free-riding — but also crowds out full, voluntary cooperation. (3/n)
We test this in an experiment varying the existence of a rule governing public good contributions & whether enforcement of the rule is biased against some players. (2/n)
