My wonderful spouse has a new book together with Bennett Capers (Fordham) and Jasmine Harris (UPenn) coming out that is sure to meteorically rise to the top of bestseller list. Pre-order here: www.cambridge.org/core/books/c... Or here: www.amazon.com/Critical-Evi...

Thx @law360.bsky.social for this write-up of the extraordinary efforts of a few judges—and now the DOJ—to block a one-word addition aimed at making Fed. R. Evid. 609 a shade less heinous. As always, your Coalition for Prior Conviction Impeachment Reform (www.reforming-pci.org) stands ready to fight.

Patent data before and after acquisitions by 8 big tech giants show that, on average, the ‘Big Eight’ firms appear to invest in the acquired technology rather than kill it. Acquired inventions become more influential, more widely cited, and more embedded in follow-on innovation.

Across 1,200 startup acquisitions by eight tech firms, innovation rises before the deal, acquired patents gain citations after it, but 31 percent of target employees leave within a year, from @florianederer.bsky.social, Regina Seibel, and Timothy Simcoe www.nber.org/papers/w35762

I believe that this is the very first time we've heard from Larry Summers since his Epstein files retirement. Is he coming back?

I did wonder which platform would cater to the demand for mean-spirited attacks on economists now that the market leader has been put out of business, but I didn't expect it to be The Economist.

Deeply saddened by the news of the passing of Randy Picker, a giant of antitrust law. leiterreports.com/2026/08/16/i...

Rival firms linked by common ownership are more likely to form cartels and to sustain them longer. After a cartel dissolves, those ownership ties are reduced, from Vincent Abraham, @florianederer.bsky.social, and Catarina Marvao www.nber.org/papers/w35565

@florianederer.bsky.social Your paper made it into the upcoming hbomberguy video on why "Adobe must die" :D

An Austrian and an Indian walk into the World Cup… a quick post-final look at what the last weeks have shown us, with @florianederer.bsky.social and Dhruv Kapoor www.buzzsprout.com/2052670/epis...

Delighted to see Lisa Kahn and Isaac Sorkin taking over as co-directors of the NBER Labor Studies Program. Two outstanding economists and thoughtful leaders. Congratulations to both, and especially to Lisa, who has been a wonderful friend and colleague for many years.

I apologize to my co-authors, but it's a little difficult for me right now to focus on doing my part of the paper revisions.

Austrian soccer highlights: It used to be: “I wer narrisch,” as of yesterday: “bist. Du. deppart.”

that Messi premium in Miami 🔥

Respectfully here to note there is a 2014 paper from my soccer-obsessed friends showing that, even for the South Africa WC in 2010, the US, Brazil, and Mexico were 3 of the top 4 non-African travelers. No surprise that this may be even more so w/US & Mexico hosting. academic.oup.com/jae/article-...

Außerdem: @florianederer.bsky.social hat sich die Ticketpreise der #FIFA bei der #WM einmal angesehen. Hat der Weltfußballverband ein Eigentor geschossen? Und: #Schweinezyklus für Juristen. @hhu.de #Kartellrecht #Monopol #Wirtschaftspolitik open.spotify.com/episode/7M4J...

For @foreignpolicy.com, @filipecampante.bsky.social, @florianederer.bsky.social, and I look at what World Cup ticket prices can tell us about what fans care about: foreignpolicy.com/2026/06/22/w...

Zumindest für einige Spielen der WM gibt es wenig Nachfrage und immer noch viele Tickets. Die FIFA könnte sich bei diesen Spielen verzockt haben, glaubt ein Ökonom. Erste Freikartenaktionen sind zu beobachten - und einige Verkaufstricks. www.sportschau.de/fussball/fif...

I talked to NBC about FIFA clandestinely dumping World Cup tickets for low-demand games onto resale platforms. This World Cup will be the ultimate K-shaped tournament for ticket prices. Some low-demand games will be almost free, but most games will be very expensive. youtu.be/pYR5Tb3D6SM?...

Absolutely stunning climbing performances and incredible consistency over 3 weeks🚴‍♀️🚴‍♀️🚴‍♀️. Kudos Felix #Gall. First 🇦🇹 to finish a grand tour GC at #2! #GirodItalia www.domestiquecycling.com/en/news/gall...

Great arguments explaining why the court got the wrong answer in the antitrust case against Meta.

The range of conflicts of interests (journal editorships, self-owned consulting LLC, children working at the ASSA meeting) disclosed in the latest AEA executive committee meeting is super interesting. www.aeaweb.org/articles?id=...

Today we hosted @florianederer.bsky.social (Boston University) for a #seminar on "Disclosure and the Pace of Drug Development", joint with Cunningham, Hodgson & Wang. More transparency, faster innovation? Think again: policy design can have surprising results! #econtwitter #Pharmaceuticals

It never gets old to see a paper come out in print. academic.oup.com/restud/artic...

The case for (high) minimum wages and collective agreements. Great op-ed introducing Arin Dube‘s fantastic new book „The Wage Standard“.

Nobody is better at restoring the public's trust in universities than a NY Times columnist lecturing students on "how to fall in love with someone" ... ... or "how to divorce your wife of 27 years for your much younger research assistant"? We are not serious institutions.

“We’ve established that this self-preferencing is real and it gives an advantage to the platforms themselves. Whether that’s good or bad for consumers is much less well-established.” www.politico.com/newsletters/...

I like conferences in general, but I can't remember one that I enjoyed and where I learned as much as the Arnold Ventures BRIDGE event on online harassment and stalking. So inspiring to meet researchers and practitioners in this field! @jenniferdoleac.bsky.social

A new antitrust case against Vail and Alterra takes aim at Epic and Ikon pass pricing. Core issue: bundling + ecosystem power Cheap season passes, but very high day tickets → steering demand, locking in consumers, and squeezing independents dicellolevitt.com/dicello-levi...

Excited to announce that our paper "Bayesian Persuasion with Lie Detection" is forthcoming in the Journal of Law & Economics ... ... with special thanks to the man who provided countless perfect examples for our analysis florianederer.github.io/lies.pdf

This joke has so many fantastic layers.

The WSJ finally officially reports what we've known since early December. NBER cuts ties with Larry Summers.

To give you a sense of how big a deal this is: Summers’ PhD advisor made NBER what it is today

LOL at "courtesy of Niall Ferguson"
