This take on my article "Legitimizing Agencies," from an AI content farm, is truly ... something.
Link in next tweet.

Whither the securities event study? The method assumes efficient mrks: investors react quickly to news (even on the back pages) affecting a single co's share price.
That doesn't square with a sell-off in AI stocks on Thursday ... in response to an election on Tuesday.

@AliceFromQueens Bothsides-ing an attack on a Michigan synagogue & pre-school is "about" Israel/Palestine only if one sees American Jews as foreign.

@dwarkesh_sp nice... but every second he's sitting for an interview is a second he's not finishing the final LBJ book!

Pleased to contribute to this @WIRED @mollyraskin story. It’s refreshingly anti-clickbait: careful reporting on unsexy legal questions--appointee vacancies, subdelegations--where the conclusions IMO are rightfully nuanced and hedged. https://t.co/nysrv8L8OY

@ZaringDavid Also nice to see this Cass Sunstein guy finally getting some attention

[Elias Neibart @EliasNeibart]

Blown away by @lsolum's very kind words about (and engagement with) Lawyer's Meaning is Lawful Meaning: "Highly Recommended! This is a marvelous paper .... On this and much else, Neibart’s article—developed with rigor and care—deserves the attention of everyone who works on statutory interpretation."

If Washington wants to subsidize $45 million companies, it should say so, rather than dressing them in Main Street’s clothes, writes @BrianDFeinstein

Penn, let's do this.

[David Zaring @ZaringDavid]

Wharton is hosting its annual financial regulation conference and unsurprisingly there’s a lot of stuff at the edge of banking. Private credit, systemic risk transfers, fintechs, ‘40 Act companies. It’s a nonbank world out there these days.

Please help me get the word out about the new websites for Legal Theory Blog and the Legal Theory Lexicon. Reposting here and on other social media sites is great. It would be especially helpful if law school faculty members could send an email to their colleagues with the new addresses. Legal Theory Blog is at https://t.co/D2xkWnXYwX. The Legal Theory Lexicon is at https://t.co/v7ihNBHjIo. Thanks in advance for you help.

This article discusses how #federallaw systematically privileges #smallbusinesses & argues that this regime of favoritism creates significant costs, while its supposed benefits are debatable.

My Wharton colleague @BrianDFeinstein has posted a impt paper on federal legal and administrative bias favoring small firms -- a foundation of democracy? A costly subsidy? Or a certain killer of the view that large firms have unwarranted political power? https://t.co/jfzOu8tkjx

[Coase-Sandor Institute for Law and Economics @UChicagoLawEcon]

The 2025 Political Economy & Public Law conference covered #research on an array of topics- from disclosure rules to Congressional oversight committees to small business-favoring provisions to executive orders. Thank you to all who made this event such a success!

[Brian D. Feinstein @BrianDFeinstein]

@sydneymlevine congrats! very well deserved

[Brian D. Feinstein @BrianDFeinstein]

@ZaringDavid Yes, and that's the 2019 program. Just imagine how much better this year's conference is.
