Spotify account gives a budget of audiobook hours before needing to pay for more hours, but if you listen to a 10-hour book at double-speed (so 5 listening hours), it counts as 10 hours of your budget. So they price r-speed listening at exactly r times that of unit-speed listening.

Boat question.

Schumer, Jeffries propose strongly-worded letter to counter RFK Jr.'s purge at the CDC.

I was under the impression these were called "siblings"

I didn’t know this!

I should check!

A kind of mechanical approach modifies Hart and Schmeidler's program to check, for every product set B of action profiles, whether some strict CE has marginal supports B_i. Then A^S is the largest B that passes the test (or empty if nothing does).

But there must be something more interpretable!

1) The set CE^S is convex.
2) There's a product set A^S of action profiles such that (i) CE^S is contained in Δ(A^S), and (ii) if CE^S is nonempty, then something in CE^S has support A^S.
3) The closure of CE^S is just the intersection of CE and Δ(A^S).

So it all comes down to what A^S is.

Has anybody developed the theory of STRICT correlated equilibria of a finite game?

I was playing around with it a bit, and here are some things that are easy to show about the set CE^S of strict correlated equilibrium distributions.

Thank you! This is all super helpful.

The set of textbooks not being a lattice, it could be that so such textbook exists.
