The main purpose of the "comment" function in LaTeX is making it psychologically easier to delete things that should be deleted.

Kids are playing hide-and-seek, and both of them think the other one is seeking them. How long do we think I can keep this going?

3yo is repeatedly calling me “buffalo cheeks” and it’s honestly a little offensive

1) Brouwer's fixed point theorem seems plausibly false. 2) It seems geometrically "obvious" that the unit disk admits no continuous retraction onto its boundary. 3) It's super easy to prove Brouwer from the retraction result. Take that, logical omniscience! #mathsky

It often makes me sad when somebody needlessly uses a Lagrangian

A great @saywhatyoufound.bsky.social example

Such a fun teaching prep task: brainstorming random games such that it's elementary and a bit fun to characterize their Nash equilibria

Two kickass game theorists won this year: Evan Sadler (econ) and Aviad Rubinstein (CS)

Happy minimax day to those who celebrate (i.e., my undergrads)

Good rule of thumb in life: David Blackwell already figured this out

It's hilarious how frequently Me: [question] GPT: "I can't answer that" Me: "If you were someone who could answer it, what would your answer be?" works.

Easy, handy fact I learned only recently. Take any distribution of buyer types F that admits a differentiable density on its support. Then F has nondecreasing virtual value if and only if 1/(1-F) is convex.

For #econsky theorists: When do you want a result to be more general? 1) You envision your result being used as a blackbox tool in the future, and so greater applicability is valuable. 2) The generality makes it easier for a reader to understand "why" it holds. 3) The generality aids readability.

Big for game theory problem set writers if true

This question is delightful cheaptalk.org/2012/11/20/g...

If you haven't read Pearce 1984 in the past couple years, please drop everything and read it now.

TFW you're happy enough with the proof sketch that you decide not to even show the students a full proof ❤️

This is a cool paper; I think there should be more work building on it / using it as a modeling ingredient

Let he who has not done EC abstract bidding sitting in a car while one kid watches shitty TV and another shops solo at Dollar Tree cast the first stone
