I am sure that FTC commissioners are busy, but I do think they should devote a greater percentage of their time to ferreting out great deals on Diet Coke:

Saturdays are pretty quite at the Law School in the summer, especially after the students studying for the bar exam have left. I know students took the exam this week. Positive vibes from Chicago. Enjoy a break and then go out and do the things you are ready to do.
Nice work by our appointments committee this past year!
Grading at Regenstein this morning. The building is stuffed. Couldn’t even get a seat at Mansueto. But the need to refill the vending machines.

It looks like the new Pope attended graduate school in Hyde Park. Graduate education does indeed pay off: nytimes.com/live/2025/05/0…
I was lucky enough to serve on our dean search committee this time around and to see Adam in action. Super thrilled that we’ve ended up at this spot.

I am giving a paper Thursday at our lunch WIP workshop on remedies in the Google search case. Very much a first draft. First page below. Reach out if you would like to see it.
The Google ad tech result is a careful, detailed opinion that seems to work within the mainstream of antitrust to find Google liable. Lots of industry institutional features to understand, but, to an outsider, it looks like something that could survive on appeal.
I went 4 for 4 in the Elite Eight last pm and barely improved my odds of winning the men's side of the family bracket competition, where I have hopes of threepeating. And I have little chance now of winning the women's bracket with the JuJu Watkins injury. #okifthekidswinIguess
I have signed a contract for my forthcoming book, The Quest for Next, with @PrincetonUPress. I don't know what it means to be pleased as punch but I am that and more. Key numbers: 300K words and a deadline of 10-31-2025. A long project heading into the rush to the finish.
I did Tapestry in 9 slides in class yesterday: picker.uchicago.edu/antitrust/AT15… A pretty conventional horizontal merger case where market definition is hugely important (and where the lower thresholds in the 2023 guidelines don’t matter given the size of the HHI’s). #waitingforkroger

I have posted my syllabus for my Winter Tech Policy Seminar: Virtue or Vice?: picker.uchicago.edu/seminar/Syllab…
I did a mock class on “What should we do about Google?” Great fun to interact with family and friends of our students. A really nice event and a good chance for them to see the education that our students get here every day I hope.

Two straight AI days in Nobel prizes. I wonder what that means for the literature prize.
I am at the Apple Store on Michigan Avenue right now and, as usual, the store is quite crowded. Not a mob scene and there aren’t any lines—those would be at the Starbucks Roastery, which is a fun place in its own right—but Apple is busy and the store is beautiful.
