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.

Congrats @svanbaal.bsky.social!

Don’t let your work break your soul. I remember well how it lifted our spirits when we—being young RAs at the University of Vienna—were looking for guidance!

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)

Matthias Kasper @mkasper.bsky.social · Apr 29

Surprisingly, we find no evidence that biased audits erode norms, reduce cooperation, or diminish compliance. (4/n)

Matthias Kasper @mkasper.bsky.social · Apr 29

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)

Matthias Kasper @mkasper.bsky.social · Apr 29

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)

Remember the "Highlights" that some Elsevier journals require? Dean Karlan and friends developed an amazing way to troll them: haikus!

That’s a wrap!

Thank you for a great workshop on economic and consumer psychology hosted by the Walter Eucken Institut at @uni-freiburg.de.

Looking forward to continuing the conversation at the University of Vienna in 2026!

🚨 Big SCOOP 🚨

Tax revenue could fall by as much as **10%** this year, per sources, as taxpayers and businesses see the Trump admin as less likely to challenge tax cheats.

That'd be **$500 BILLION** in lost revenue.

It'd nearly double the tax gap in a single year.

Tax revenue could drop by 10 percent amid turmoil at IRS

Staff cuts and disruptions related to the U.S. DOGE Service have officials bracing for a sharp loss of revenue.

Tax SCOOP: Trump administration plans to cut staff at the Taxpayer Advocate Service -- the taxpayer help center -- by more than 25%

These are jobs designed to help people struggling with their finances, identity theft or other tax issues.

Trump administration plans 25 percent staff cut at IRS taxpayer help office

The Taxpayer Advocate Service, which operates as an internal watchdog, would see deeper workforce reductions than the agency overall.
